Read case study examples of good practice to deliver quality service and meet the needs of under-served groups
Back to Health inequalities index page
These case studies showcase good practice in meeting the needs of under-served groups and delivering quality care to service users who may be particularly vulnerable to health inequalities.
The case studies illustrate successful examples of speech and language therapy practice, but it should be noted that each service user is an individual and it should not be considered that the care exemplified in a case study is suitable for all people who meet the descriptions given.

This case study examines how support is provided to a non-English speaking family, with consideration of their cultural beliefs around mental health.
What was the clinical challenge?
In an adult mental health context, we worked with a young South Asian male patient diagnosed with schizophrenia and, subsequently, autism. His parents spoke Hindi and lacked awareness about mental health illnesses, as well as how to navigate through the NHS system.
How did you gather the information that you required?
In order to help meet the needs of the local population, the service has employed a Band 4 speech and language therapy assistant, who can speak several South Asian languages. Both the assistant and the therapist working with the family are Indian and were able to use their own experiences, alongside knowledge of appropriate vocabulary and possible perceptions of mental health in this community.
How was the information you collated used to improve the care for the individual/community/group?
What was the outcome?
The family were given the information in the language and context that they could understand and were also given the time and opportunity to discuss their specific concerns around stigma and their community. Staff worked together to ensure individuals with relevant experience and cultural sensitivity were able to use and share their knowledge. This way of working continues to be embedded in the care of all individuals in this setting.

People with a learning disability are more likely to experience health inequalities (NIHR 2020), so supporting this group of people to be able to access and implement public health information is particularly important. Up to 90% of adults with a learning disability experience some form of communication difficulty (RCSLT 2013) and literacy levels among this group are known to be low (All party parliamentary group for education 2011).
The learning disability speech and language therapy team worked with a group of experts by experience (the Southampton community learning disability team service user group) to identify public health issues that matter to them. These issues included: physical activity, healthy eating, oral hygiene and mental wellbeing. The experts by experience worked jointly with the speech and language therapist (SLT) and SLT assistant on this piece of work. They spent three sessions on physical activity, and three sessions on healthy eating. These sessions involved:
After reviewing each app, arranging a road show event, visiting a local college/day service, sharing the key public health messages and demonstrating the apps, they rated favourably to other people with a learning disability. The roadshows were popular with attendees and a lot of people were interested in the apps. There were between four and fifteen people attending each roadshow event.
The group reviewed digital apps relating to areas that might be useful in supporting people with a learning disability keep physically active and eat healthily. They focused on each topic for three sessions (one session per month). The group reviewed the usefulness and accessibility of six different apps while learning more about the public health messages associated with them. The group then shared their learning with their peers at day services/colleges.
At the start of this study, none of the members of the Southampton Service User Group had ever used an app to help to support their health, although some members of the group were familiar with the term ‘apps’. Members reported that they would not use the internet as a source of health information. Awareness of public health related messages was generally low. For example, one member of the group thought we should aim to complete thirty minutes of exercise a week. This knowledge was raised, by the end of the work, he said twenty minutes a day.
The group rated 33% of the apps reviewed as useful and accessible. The apps they could relate to and incorporate into their daily routine were rated favourably. Barriers to accessibility included: issues with images, text size and overall ease of use.
Following this piece of work all members of the Service User Group reported that they were more likely to use the apps to support their health in the future. There was also an increase in the groups understanding of public health messages relating to physical activity and healthy eating. The group reported really enjoying the roadshow events particularly sharing their learning with other people with a learning disability and demonstrating the different apps.
Were there any challenges you had to overcome?
Not all apps available to support with public health are viewed as accessible by people with learning disabilities. However, there are apps which are rated as being accessible and clinicians working with adults with learning disabilities should signpost people to them and support them to access these to enable them to have the opportunity to manage their own health.

I received a referral for Mr A who was dysphagic and, following inpatient videofluoroscopy, had opted for an International Dysphagia Diet Standardisation Initiative (IDDSI) Level 4 pureed diet, which reduced the degree of aspiration. The referral requested I support setting Mr A up with these recommendations when home.
The referral stated that Mr A spoke Tamil and that he had possible mild memory and cognitive impairments. It also stated that he lived alone and had one daughter who spoke English, but phone calls with an interpreter revealed he was now living with his other daughter “P” who spoke Tamil, not English. P prepared Mr A’s meals.
Since coming home, Mr A had been having a subset of his meals which would blend into puree but it made him “feel sick” and reduced his diet intake, leading to weight loss. He said the doctors in hospital told him to start having pureed food so he had carried on. He wasn’t sure, or couldn’t remember, why he was having pureed food.
Mr A and his daughters then asked me about a range of foods that he wanted to eat and which IDDSI level they would be. I knew almost no Sri Lankan foods, aside from one or two items I happened to have had from a local Sri Lankan takeaway.
I wrote down the food names and we used Google image screen sharing, with family members holding items to the camera and describing items with the interpreter, to help me to understand exactly what presentation of the foods he was asking about. We agreed I would research options and come back to them with ideas of which foods fell into which IDDSI level.
I couldn’t find any IDDSI Level information sheets with examples of Sri Lankan foods online. To get this information myself, I tried some of the foods from my local Sri Lankan takeaway, spoke to the takeaway owners about the other foods, and continued to research different ways of preparing the foods online.
I presented the options again with the foods categorised into IDDSI levels with pictures and explanations of which features made them this texture. I made it clear which features made the foods correspond to each level, in order to help to try and generalise the concepts for other foods Mr A and his family eat.
Mr A expressed that he felt he would eat enough and enjoy meals made to the IDDSI Level 6 soft and bite-sized texture. Across the next few weeks, I phoned Mr A and P with an interpreter. We discussed how to: aid P in preparing meals, answer questions about further foods, monitor Mr A’s diet intake and chest status, and check he found the texture remained within his wishes across time.
This clinical case made me aware of the gap in resources for non-White British/American patients and led me to create a website for Swallow’s Kitchen for SLTs to make these info sheets with service users/multidisciplinary team (MDT) staff/interpreters etc. and share with other SLTs. I am making my first leaflet with a nursing home that has a large cohort of patients who eat traditionally Indian foods, and have an offer from the Sri Lankan takeaway to continue to make the leaflet for Sri Lankan foods.
Do you have any anonymised clinical data that you could share, to illustrate your case (eg language samples, observations, swallow test results and so on)?
You can see some examples of Sri Lankan foods I classified (PDF) .
Not being familiar with the foods the patient was asking me about and lack of resources for me to find this information was a real challenge. It felt embarrassing and almost discriminatory not to be able to answer these questions, given I knew if a patient/family member of a similar cultural background to myself had asked I could answer then and there myself and easily email them various IDDSI leaflets with multiple examples from within their usual diet. I also knew to be mindful of how one Sri Lankan family prepares food may differ from another.
There is a big gap in SLT resources for non- White British/American patients and it’s possible individual SLTs may be doing this work in isolation from each other, which is why I have started the website.
Do you have any tips for other members in similar situations?
Do the research! We owe it to our patients of other cultures to treat them equally to our patients who eat the traditionally British foods we know well. If you can, please get involved with Swallow’s Kitchen so we can try and narrow the resource gap. There has been lots of interest for Swallow’s Kitchen on Twitter and in CENs, however few other SLTs/student SLT have volunteered to make a leaflet at this point. It would be great if others were aware of this and in a position to make more leaflets!
I think this is important to facilitate more equal access to information, prevent delay to care for patients of other backgrounds and to reduce the chance of misunderstanding, which would otherwise lead to patients of other cultures being given foods that have not been agreed as in their best interests. I hope leaflet-making can be used as student placement projects and can also be used as opportunities to help patients, families, carers and others who collaborate on leaflet-making understand (their) dysphagia better.

We had lengthy waiting lists in the speech and language therapy service, and we had a vacant full-time SLT post. At the same time, many parents of children, particularly the mothers, and older adult patients did not speak English and I felt it was impossible for us to deliver services without interpreters, alongside the necessary information regarding cultural differences. We had worked with the interpreter unit but we needed more interpreter time than they could offer, and we needed to train the co-workers specifically to work with our client groups.
I found out more about the local populations (Oldham) – it had (and still has) one of the highest South Asian populations of any town – 18.1 % (England total 14.3%). For our caseload, I needed both Urdu and Bangla speakers in particular, who could also translate our information leaflets. I sought advice from an existing NHS interpreter / translator unit, whose services I had used before too.
I converted a vacant full-time SLT post to two bi-lingual co-worker posts.
This transformed our services. Bilingual co-workers are needed if we are to provide an effective service to ethnic minorities. Following the success of this, I later obtained funding for another co-worker and brought in some minority ethnic interpreters for other groups such as the Pashto-speaking Afghan population.
In a community adult SLT setting, I received a referral from the acute hospital team for “Mr A” who was deemed to be “feeding with acknowledged risk of aspiration” across consistencies. The referral told me in hospital that Mr A had opted for the diet texture which reduced the degree of aspiration on inpatient videofluoroscopy – the International Dysphagia Diet Standardisation Initiative (IDDSI) Level 4 pureed diet. The referral requested I support setting Mr A up with these recommendations when home.
Since coming home, Mr A had been having a subset of his meals which would blend into puree but it made him “feel sick” and reduced his diet intake leading to weight loss. He said the doctors in hospital told him to start having pureed food so he had carried on. He wasn’t sure, or couldn’t remember, why he was having pureed food.
The initial aim was to ensure Mr A and his family understood his needs and could make informed decisions about his diet. During discussions, different cultural opinions on the roles of professionals also emerged.
Based on the referral, I knew that I needed to contact Mr A with a Tamil interpreter and that he would likely benefit from short and repeated information. It was also important to personalise the information to Mr A to aid him to relate the options to concrete options in his life. In previous telehealth appointments I gathered examples of which Sri Lankan foods Mr A enjoyed eating and ensured I understood how these would usually be prepared for him, such that I could categorise them in IDDSI levels and present the options visually to Mr A in a powerpoint to support decision making ( see case study example 3).
We arranged a video call with Mr A, his daughters, and a Tamil interpreter. I shared videofluoroscopy findings through a presentation including short written sentences the interpreter could translate, and pictures supporting what I was saying, eg of a videofluoroscopy, of hospital, of usual IDDSI meal examples.
After the information was given, questions asked if he had understood and retained the information and had capacity to make the decision, alongside the options offered; Mr A asked me what he should do. I explained it was his choice, but this led to the family and interpreter laughing and saying, “you’re the doctor here, you tell him what to do”. I explained the roles within mental capacity assessment and said we could make the decision “together” balancing the costs and benefits of the options.
I was clear about what the roles were and took a “meet in the middle” approach saying we’d decide “together” what to do. I continued asking questions for Mr A to express his opinion such that we were able to have a constructive discussion about appropriate diet and meal preparation (for further information, read case study three ).
Use an interpreter and don’t rely on family members. Check the language and dialect before requesting an interpreter. It can be helpful to have written sentences for the interpreter to interpret for some contacts, for example, here, key information I’d prepared in a simplified form.
Consider how to balance different cultural norms of your roles. I did this by trying to be transparent of what role we each had in the legal framework of mental capacity assessments.
Is there anything you would do differently in future?
It would be useful to have more guidance on how to best manage cultural differences in mental capacity assessments. I don’t know if there was a better course of action for managing this. I could have done as asked and expressed what I would do in his position. However, I didn’t feel comfortable doing this given this is not part of the role I learnt that an SLT has in these mental capacity assessments.

Our youth offending service (YOS) deliver services to children aged 10 – 18. The children receive routine screenings from specialists based within the YOS, which contribute to the essential AssetPlus assessment overseen by the Case Manager (CM). Many of the individuals within the YOS population are at increased risk of experiencing health inequalities, eg due to poverty; poor social support; poor health literacy; being from some under-served ethnic/cultural groups that are over-represented in the youth justice system.
During the COVID-19 pandemic, the speech and language therapist (SLT) and restorative justice officer (RJO) identified a gap in team communication that had been created by the pandemic. Furthermore, face-to-face appointments with children were no longer possible.
There was no standard process in the team for coordinating the specialist screenings that take place at the onset of the child’s involvement with YOS and as such, their experience varied depending on which CM they were allocated to. Subsequently, differences in each CM’s operational approach and the impact on engagement became more apparent.
Children and their families were reporting being overwhelmed from poorly coordinated separate phone contacts from specialists, eg several hours of screenings attempted on the same day; or when families had not yet spoken to the CM and/or had not been informed of the screenings, specialists had attempted screenings without providing reasonable adaptations due to a lack of information, eg interpreters, avoiding potentially triggering/retraumatising topics or arranging COVID-19 compliant face-to-face meetings for those experiencing digital poverty. This led to inequitable health outcomes for the clients.
Incidents involving children becoming distressed at repeating traumatising history were common.
The SLT and RJO raised the issue with other health specialists in team. The team agreed that in order to be trauma-informed, it was necessary to clarify the intake pathway, specify that information must be shared prior to specialists contacting the family and outline the coordinating role of the CM.
The SLT approached the head of YOS who agreed and the change was introduced to CMs. The SLT checked with the NHS line manager and information governance team that information sharing from health system for the purposes of safeguarding was appropriate at this early stage of client input.
The head of YOS formalised and distributed new intake pathway process requiring virtual ‘Case Coordination’ meetings as mode of information sharing.
Head of YOS introduced performance management aspects to enforcing Initial Case Coordination Meetings in September 2020 after inconsistent implementation across CMs
There were 60 initial case coordination meetings carried out between August 2020 and end of March 2021.
Information regarding SLCN; physical and mental health; family factors including contact with social care; education and SEN; substance misuse; current and prior offences as well as contact with local child criminal exploitation agencies able to be shared across team at beginning of contact with service.
Feedback from families and specialist team has been positive, who feel screenings are better prepared for and engagement with children and families is improved.
There are numerous examples where screenings have been individualised to suit the needs of the client and address health inequalities:
Initially the specialist team attempted to initiate the service change by introducing the idea for discussion at a whole team meeting. The emphasis was initially to allow for better time management in regards to scheduling and meeting screening deadlines for the specialists within the YOS team. This did not create buy-in from the case managers who would ultimately be responsible for coordinating the meetings and the feedback from some was that it would be another task to manage on top of having to adjust to the pandemic.
However once this was fed back to management, they were responsive and were able to provide direction; clear protocols; wider strategic rationale in line with the Hounslow YOS objective to become a trauma-informed service; and structures for performance managing CMs to ensure they were implementing the change.
Is there anything you would do differently in future or ongoing learning that you want to share?
Future plans involve developing more structured outcome measures to capture the positive impact of the meetings. This might involve approaching parents and children for their feedback about the screening process as well as comparing DNA/unsuccessful screening contact information before/after the meetings commenced during the pandemic
Next time a change in protocol is suggested, baseline information about how the change will create more resources for the children and young people (eg SLT intervention time) for the children should be presented/emphasised to promote initial buy-in from the CMs.
Up to this point, implementation oversight has focused on whether the meetings are carried out consistently across the team. Future oversight may seek to capture the quality of the meetings, ie whether the CM has had an initial discussion with the family prior to holding the meeting so that current circumstances may be shared with specialists; whether information about co-defendants has been readied for sharing with the RJO.
Management are also considering how to incorporate a similar model for exit planning at the end of a child’s journey with the YOS.

Women are nearly twice as likely as men to suffer from mental illness. This gender disparity in depressive disorders may relate to social inequalities and living standards across nations. Currently, these disparities were not reflected at the level of health policies. This study utilized global data for depressive disorders and socioeconomic data from the United Nations’ World Bank databases and Global Burden of Disease database to demonstrate the correlation between social inequality and gender disparities in mental health. This study investigated the association among the ratio of female to male depressive disorder rates, gross domestic product, the GINI Index, and the gender inequality index for 122 countries. The research yielded some major findings. First, there exists a significant correlation between gender inequality and gender disparities in mental health. Second, the GINI index is significantly associated with male—but not female—depressive disorder rates. Third, gender disparities in depressive disorders are associated with a country’s wealth. These findings can help to inform society, policy-makers, and clinicians to improve the overall health level globally.
According to the World Health Organization (WHO), depressive disorders are major contributors to the world’s health burden; they affect approximately 350 million people worldwide 1 – 3 . Women are nearly twice as likely as men to suffer from mental illness 4 – 6 . Although this gender disparity in mental health is reported across diverse geographical regions, societies, populations, and social contexts, there is a dearth of research that explores a link between the impacts of social inequalities and gender disparities on mental health. In this study, the social inequalities include both gender inequality and wealth inequality. Understanding gender disparities in health is very important, according to the National Institutes of Health 7 – 10 . A growing body of research indicates that psychiatric disorders are largely caused by a combination of stress, environmental, neurobiological, and genetic factors. These poorly understood factors significantly limit the development of effective treatments for these disorders. The major causes for depressive disorders cannot be completely explained by genetic factors 11 – 13 . The contributions of genetic architectures are difficult to address at the level of health policy. Therefore, attention to social factors, especially with regard to inequality, is critical in approaches to mental health; these factors can be improved dramatically through the implementation of appropriate governmental policies and heightened community awareness.
The brain structure and response to stress are different between females and males 14 , 15 . For example, community pressure regarding stereotypical social roles based on gender may impact mental health responses differently in women and men 16 . In a male dominated culture, women and men may deal with competition in their workplaces differently. Previous studies also investigate the potential relationship between hegemonic masculinity and mental health in men 17 – 19 . Human genetic variation exists both within and among populations. These relevant genetic characteristics as well as stress could contribute to gender disparities in mental health 20 . The gender expectations and masculinities may also play an important role in gender disparities in mental health 17 , 21 , 22 . In a more general context, gender inequality includes but not limited to domestic violence, sexual abuse, unpaid caring work, higher hours of work, low social status, lack of access to reproductive rights and education 23 – 27 . Furthermore, the areas related to gender inequality include public health, social work, sociology, and social psychology.
Both gender inequality and wealth inequality have an impact on women’s health at the country level 26 , 28 , 29 . For gender inequality research, a series of WHO reports provided in-depth reviews of available literature on the topic of gender equality and mental health in 2000 30 . Since then, there are some studies that have attempted to examine the association between gender inequality and gender disparity in mental health at the country level 31 , 32 . However, until now the evidence remains inconsistent for the possible impact of gender inequality on gender disparity in mental health 31 – 34 . In 2007, one study utilized the data from both high income and low and middle income countries and proved that gender equality has no or little impact on the gender disparities in depressive disorders 32 . In 2013, one study, based only on European countries, claimed the potential impact of gender equality on reducing the gender disparity in depressive disorders. Unfortunately, they were unable to provide statistical evidence to prove this association 31 . Therefore, at the global level, the direct statistical evidence to show the association between gender equality and the gender disparity in depressive disorders remains absent.
Wealth inequality has become a frequently and widely discussed topic 31 , 35 – 38 . Wealth inequality has impacted general health, including mental health 39 – 42 . Furthermore, the impact of wealth inequality on mental health has also been investigated 43 – 45 . Wealth inequality and income inequality are different (Note 1): income represents the money received on a regular basis, while wealth represents the money or properties owed over a lifetime. However, research that attends to gender disparity in depressive disorders and the wealth inequality is limited.
This paper presented the statistical evidence to address this gap in the literature. The WHO has published a series of comprehensive reports about mental health 34 , 46 , 47 and has made a significant effort to collect the data that has permitted an exploration of the gender disparities in mental health 29 , 30 . The study in this paper captured the impact of social inequality on gender disparities in mental health. Previous studies that have not adequately addressed this problem typically analyzed the data using gender (Notes 2) as a dichotomous variable. Moreover, the scope of many studies has been limited to specific countries 24 , 48 – 51 . For example, one study that indicated the potential correlation between the wage gap and gender disparities in mood disorders was limited to the United States and only used the wage gap to measure gender inequality 24 . Another study conducted only in South Korea also indicated that gender inequality might have an impact on mental health. In 2004, one study 27 , conducted in the United Kingdom, indicated domestic violence and abuse toward women related to the greater prevalence of mental illness among women. There is a need to utilize global datasets to identify the impact of inequality on mental health. Unlike existing studies, this study utilized mental health datasets at a global level to conduct the analysis; and the analyses in this study directly focused on the gender disparities on mental health. The novelty of the study in the paper lied in both data integration and the analysis. In order to illustrate the way that the present analysis can be used to better capture the relationships between mental health and inequality, this research also focused specifically on depressive disorders. All of the data were extracted from publicly available datasets and these data represent the largest sample size so far, due to the recent availability of global data on depressive disorders from the Global Burden of Disease database. The novelty analysis was straightforward: the ratio of depressive disorder rates for female to male is used directly as a dependent variable. In this way, gender disparity in depressive disorders can be modeled directly.
A series of statistical models were applied to examine the relationship between gender disparities in mental health and socioeconomic factors. Particular attention was paid to both gender and wealth inequalities. The study aimed to identify whether or not gender disparities in mental health are related to social inequalities, as well as to identify whether or not females respond differently to stress provoked by social inequality as evidenced in mental health outcomes. In this study, social inequality included both wealth inequality and gender inequality. The research was designed to inform public policy as well as to help health professionals reduce gender disparities in mental health and broadly improve mental health outcomes.
Mental health data were obtained from the Global Burden of Disease datasets (GBD) website ( http://www.healthdata.org/gbd/data , 1 May 2016) 2 . The socioeconomic factors analyzed in this study were the Gender Inequality Index (GII), the GINI Index, and Gross Domestic Product (GDP).The socioeconomic data (GII, GINI Index, and GDP) were obtained from the United Nations’ databases (World Bank and World Economic Forum, 1 May 2016) 52 – 54 . All datasets were combined by country codes.
For mental health data, depressive disorders data, including major depressive disorders and dysthymia, were extracted from the GBD database. In order to obtain the most comprehensive dataset, this study include all clinical case definitions that are consistent with the description of diagnostic criteria for the International Classification of Diseases (ICD) 55 or Diagnostic and Statistical Manual of Mental Disorders (DSM) 56 . The difference between the diagnostic criteria has been tested and no significant difference has been identified 57 .
In the GBD, the Disability-Adjusted Life Years (DALYs) were calculated by arriving at a sum of the total years of life lost due to premature mortality and the years of life lived with disability to measure health loss based on both mortality and non-fatal health burdens 2 , 15 , 46 . The DALY burdens of depressive disorders were obtained from the GBD by country, region, age, and gender for the years 1990, 1995, 2000, 2005, 2010, and 2015. The gender data included the rates of depressive disorders for females, males and both combined. The rates of depressive disorders are referring to the rate per 100,000 of depressive disorders measured by the DALYs. The DALYs combines premature mortality as years of life lost (YLLs) and disability as years lived with disability (YLD) 58 , 59 . According to WHO 2 , estimates of mood disorders, anxiety disorders, and schizophrenia were calculated and improved with epidemiological evidence and, modified health states and disability weights for GBD databases in 2000s 60 , 61 .
The first dependent variable in this study is the log-transformed ratio of depressive disorder Rates for Female to Male (log-transformed RRFM) per 100,000. The second dependent variable in this study is DALYs for Depressive Disorder Rates Per 100,000 persons (DDRP) for either of gender.
The study utilized GII data to determine gender inequality 53 . The GII is a composite measurement of gender inequalities. It measures the loss for women as a result of gender inequality in three areas: reproductive health, empowerment, and the labor market. This index ranges from 0 to 1; the higher value indicates a greater level of inequality. The United Nations Development Programme introduced the GII index in its 2009 and data are available from World Economic Forum Global Gender Gap Index 2014 53 , 54 .
For socioeconomic data, the GINI Index measures wealth inequality as a distribution of a country’s residents. The index ranges from 0 to 1, and the higher value indicates greater inequality. The GDP measures monetary value of all final goods and services produced in a specific time period. Per capita GDP, in purchasing power parity units may be obtained from World Data Bank. Both GDP and the GINI Index are World development indicators. For the purposes of this study, both the GINI and GDP were obtained in current international currency from the World Bank for the years 1990, 1995, 2000, 2005, 2010, and 2015. The average for those years was calculated for each country. The selection of countries was based on the availability of mental health and socioeconomic data, including GII, the GINI Index, and GDP. The countries with missing data in any of the following categories were removed: depressive disorders, GBD, GII, GINI Index, and GDP.
A log-transformed RRFM per 100,000 of depressive disorders was estimated as dependent variable. The independent variables include socioeconomic factors determined by using GII, GINI, and GDP with random intercepts determined for ages and regions. The data preparation included log-transformed RRFM and rescaled socioeconomic indexes by a traditional z-score transformation. The log-transformed RRFM allowed the data to more closely reflect a normal distribution. Similarly, the rescaling of socioeconomic indexes permitted the data to be handled more appropriately for statistical analysis than directly using socioeconomic factors as their original scale, because the original scale of GII and GINI ranges from 0 to 1; while the original scale of GDP ranges from 0 to a real number.
The control variables include ages, regions, and years. Age groups were divided into the following categories: under 5 years of age, 5–14 years of age, 15–49 years of age, 50–69 years of age, and 70 years of age or older. Mental health data from 122 countries (Fig. (Fig.1) 1 ) for seven super-regions were included. The super-regions were East Asia & the Pacific, Europe & Central Asia, Latin America & the Caribbean, the Middle East & North Africa, North America, South Asia, and Sub-Saharan Africa (Table (Table1). 1 ). The years were 1990, 1995, 2000, 2005, 2010, and 2015.

The mixed models 62 were fitted using STATA 14 63 . There were six models that were appropriate for the investigation of the relationship between GII and log-transformed RRFM. In the first model, the log-transformed RRFM was estimated as dependent variable. The independent variables include GII, GINI, GDP, and region, with age as a random effect. In the second model, the log-transformed RRFM was estimated as dependent variable. The independent variables include GII, GINI, and GDP, with age, year, and region as random effects. For model 2, the formula is:
where the component relative_rate ijk is the relative ratio of female to male mental disorder (Ratio of Rates for Female to Male) as a function of GII, GINI, GDP for region k , year j , and age i . The random effects are age b i , year c j , and region d k . The equation highlights the relationship between relative ratio and gender inequity.
In the third model, the log-transformed RRFM was estimated as dependent variable. The independent variables include GII, GINI, GDP, region, and age, with no random effect variables. The purpose of fitting the third model was to compare the difference of coefficients between the mixed models and a linear regression model. These models highlighted the relationship between the log-transformed RRFM and gender inequality and wealth inequality, with adjustments for GDP. The potential collinearity among predictors was examined using variance inflation factors (VIF). The direct relationship between log-transformed RRFM and GII also was calculated using a Pearson correlation.
Models 4, 5, and 6 were fitted to best identify whether or not the rate per 100,000 of depressive disorders (DDRP) evidenced a direct relationship with any of the socioeconomic factors for females or males. The female DDRP (Model 4), male DDRP (Model 5), and both genders’ DDRP (Model 6) were separately estimated as dependent variable. The independent variables include GII, GINI, GDP, with age and region as the random effects.
The depressive disorder rates per 100,000 population (DDRPs) remained relatively stable from 1990 to 2015 for females and males (Fig. (Fig.2). 2 ). For all seven of the super-regions, the mean number of depressive disorders for females was approximately twice that of males, with a range from 1.63 to 3.89. Based on the data from the GBD (Fig. (Fig.2), 2 ), the Sub-Sahara African region had the highest number of depressive disorders for both females (453,705) and males (225,474), whereas the East Asia & Pacific region had the lowest number of depressive disorders for both females (190,818) and males (60,777). The Sub-Sahara African region yielded the highest value, while the regions of Europe & Central Asia the lowest value for gender inequality.
The average depressive disorders for females, males and both genders combined for each region
Statistically significant correlations were found between the log-transformed RRFM and GII, as well as between the log-transformed RRFM and GINI index once the mixed effect model was fitted (Table (Table2). 2 ). The estimates from the three models were very similar. In Model 1, the VIF score for GII is greater than 2; for Model 2, in which the region effect was considered as a random effect, all of the VIF scores were less than 1.8.
Results of statistical analysis between Ratio of Rates for Female to Male (RRFM) and socioeconomic status (GII, GINI, and GDP) for Models 1–3
Model 1, RRFM was estimated as dependent variable. The independent variables include GII, GINI, GDP, and region, with age and year as random effects
Model 2, RRFM was estimated as dependent variable. The independent variables include GII, GINI, and GDP, with age, region, and year as random effects
Model 3, RRFM was estimated as dependent variable. The independent variables include GII, GINI, GDP, region, and age, with no random effect variables
There was a significant association (Table (Table2) 2 ) between the GII and RRFM. However, no direct associations were found between the GII index and female DDRP and no associations were found between the GII index and the male DDRP (Table (Table3, 3 , Models 4 and 5). Furthermore, there were no associations found between the GII and DDRP for both genders (Model 6 in Table Table3). 3 ). The results together demonstrate that GII index is a hidden factor that correlated with the log-transformed ratio of female to male rates of depressive disorders.
Results of statistical analysis between Depressive Disorder Rate Per 100,000 population (DDRP) and socioeconomic status (GII, GINI, and GDP) for Models 4–6
Model 4, female DDRP was estimated as dependent variable. The independent variables include GII, GINI, GDP, with age and region as random effects
Model 5, male DDRP was estimated as dependent variable. The independent variables include GII, GINI, GDP, with age and region as random effects
Model 6, both genders’ DDRP was estimated as dependent variable. The independent variables include GII, GINI, GDP, with age and region as random effects
Interestingly, there were associations between GDP and RRFM (Table (Table2). 2 ). Moreover, DDRP for both genders evidenced significant associations with GDP (Table (Table3; 3 ; Model 6: −0.048 [−0.074, −0.021], P -value < 0.001 for both genders). This shows that societies with higher GDP had lower rates of depressive disorders for both genders.
Greater GII was related to greater RRFM (Relative Ratio (RR) in Table Table2 2 Model 1: 1.043, [1.034, 1.053]; P -value < 0.001). However, for the GINI Index, the greater GINI Index at the country level was related to lower RRFM (RR in Table Table2 2 Model 1: 0.976, [0.971, 0.982]; P -value < 0.001). For the GDP, there was a significant association between RRFM and GDP. Additionally, the Pearson’s correlation coefficient for RRFM and the GII index were significant (−0.151; P -value < 0.001).
This study demonstrated that social inequalities demonstrated a differential impact on mental health for females and males. For GII, greater gender inequality was significant (Model 1: 1.043, [1.034, 1.053]; P -value < 0.001) and related to the decreased gender disparity in depressive disorders. This finding strongly suggested that women suffer mentally more than men in societies with greater levels of gender inequality. Combined with the significant correlation between RRFM and the GII index (1.043 [1.034, 1.053], P -value < 0.001), gender inequality had a significant impact on gender disparities in depressive disorders. This study provided evidence that social factors, especially gender inequalities may have significant impact on gender disparities in depressive disorders.
This study identified three major findings. First, gender inequality was significantly associated with increased gender disparities in depressive disorders. Previous studies that analyzed depressive disorders separately for females and males failed to detect the association between GII and mental disorder rates that was found here (Table (Table3 3 ) 11 . This study demonstrated that gender inequality may be associated with slightly higher DDRP for females (Model 4: 0.039 [0.001, 0.081], P -value = 0.061). Moreover, gender inequality was associated with slightly lower DDRP for males (Model 5: −0.027 [−0.067, 0.013], P -value = 0.180). This study identified a significant association (Model 1: 1.043 [1.034, 1.053], P -value < 0.001) at the level of ratios, rather than at the level of rates. This distinction permitted an identification of the role that gender inequality played in depressive disorders.
Table Table3 3 provides the information about the relationship between gender inequality and the mental health for female and male separately. For female, the estimate 0.039 [0.001, 0.081] is larger than 0, which indicates the greater gender inequality is related to the greater depression rate for women. While for male, the estimate −0.027 [−0.067, 0.013] is less than 0, which indicates the greater gender inequality is related to the lower depression rate for men. Both estimates do not reach the significance level for p values, while the P value for the ratio of female rates to male rates is significant (Table (Table2). 2 ). This is also one of the reasons why this association between gender inequality and mental health is hidden. Gender inequality includes but not limited to domestic violence, sexual abuse, unpaid caring work, higher hours of work, low social status, lack of access to reproductive rights and education 23 – 27 . The stress responses have been linked to depression 43 , 64 . In a male dominated culture, women and men may deal with competition in their workplaces differently. Previous studies also investigate the potential relationship between hegemonic masculinity and depressive disorders in men 17 – 19 .
Second, men suffered from more mental health problems than women when dealing with situations of high wealth inequality (Models 4 and 5). This finding challenged assumptions that females would prove more emotionally or mentally sensitive to many social inequalities 65 , 66 . However, a high GINI index was significantly associated with high DDRP for males (Model 5: 0.027 [0.001, 0.053], P -value < 0.05), whereas a high GINI index is not associated with high DDRP for females (Model 4: −0.013 [−0.039, 0.014], P -value = 0.353). This result is noteworthy and expands upon the contributions made by a recent study 24 that indicated that the wage gap may be related to higher rates of major depression for females in the United States. One possible explanation could be that males are more mentally sensitive to wealth inequality, due to either stress or their genetic makeup 20 , 33 , 67 , 68 . From a biological point of view, the presence of the Y chromosome and different hormones could also contribute to brain reactions to the wealth inequality. Yet, stereotypical social roles could put pressure on men to excel in the work place, producing greater levels of stress in men. This possibility would reaffirm the need to address inequality as an integral part of a plan to improve mental health among males. The higher GINI index was significantly associated with lower RRFM (Table (Table2, 2 , Models 1–3). However, the decreased gender disparity in depressive disorders was due to an increased DDRP for males, as opposed to a lower rate of depressive disorder rate among females.
Third, the GDP showed a direct association with RRFM, after adjusting for other socioeconomic factors and regional effects. Yet, the higher GDP correlate with slightly higher RRFM. Moreover, GDP did correlate with the prevalence of depressive disorders for both genders (Model 6). This finding would suggest that higher overall wealth level for a country is not related to reducing gender disparity in depressive disorders. However, improving the overall level of wealth may indeed reduce the prevalence of depression in a specific population 69 – 71 .
In addition to this work’s three major findings, there was one other finding that merits mention. Different geographical locations showed different regional impacts on gender disparities associated with depressive disorders (Fig. (Fig.1). 1 ). This finding was consistent with those from previous studies 57 , 72 , 73 . These results indicate that regional or geographical effects, as well as genetic factors (population differentiation, human genetic variation for different human populations), potentially played a role in gender disparities in depressive disorders. Regional and geographical variations could be due to the combination of effects of cultural, environmental, and socioeconomic factors.
There is substantial variability existed in GII index between countries (Fig. (Fig.1). 1 ). Similarly, there are also substantial variability existed in GINI index (Supplementary Figure 1 ) and GDP (Supplementary Figure 2 ) between countries. The high wealth inequality countries tend to cluster at Latin America and Caribbean, and some countries in the south part of Sub-Saharan Africa. The countries with higher GDP tend to have lower GINI index, such as Canada, the USA, Australia, and countries in Europe. Furthermore, there are some developing countries, such as China and some countries in the north part of Sub-Saharan Africa, although the GDP is not very high, the wealth inequality index is relatively low, which demonstrate the indirect correlation between GDP and GINI index. Overall, there is a cluster tendency for all of the three independent variables. Compared to the other two independent variables, the cluster tendency for GDP index is stronger.
This is one of the first studies to successfully provide statistical evidence of an association between gender disparities in psychiatric disorders and social inequalities at a global level. These results contribute to the growing evidence that social inequality has an independent effect on population-specific depressive disorders 24 , 48 . This study was enhanced by a multi-faceted approach to the matter of inequality that utilized both the United Nations’ definition of inequality and measures of inequality such that gender inequality could be captured more precisely. The novelty in the paper lied in the analysis using existing databases. The overall results suggested that diverse aspects of social inequality, including both gender inequality and wealth inequality, evidenced differential impacts on mental health for both genders.
Caution should be exercised in interpreting and extrapolating the study results to posit broader generalizations regarding mental health. The study results only demonstrated correlations rather than causal links between inequality and depressive disorders. A focus on causal relationships between policies, such as economic, education and public health and mental health may not adequately capture the complexity of social interactions and the nature of mental disorders. The causal relationship could be further explored from the genomics and etiology aspects. Moreover, this study analyzed gender inequality and wealth inequality at the country level, and there is no apparent correlation between GII and GINI indexes. If future analysis is utilized for research on a local scale, such as at the level of community or county, the correlation between gender inequality and wealth inequality should be taken into account in the modeling process. Furthermore, attention should be drawn to the potential collinearity between the independent variables. Additionally, this study was based solely on the genders recorded in the GBD database (female, male, and both combined), with no information on lesbian, gay, bisexual, and transgender populations.
Improvement in a given population’s mental health would require a multidisciplinary policy approach that addresses socioeconomic determinants of health. Wealth inequality has become a pressing issue in a wide range of countries internationally 23 , 74 – 76 . Moreover, many researchers have shown that socioeconomic status has impacted general health 39 – 42 . Recently, many studies have focused on the gender differences regarding health 77 – 80 . Unlike most previous studies on inequality and health, this research specifically demonstrated the association between the effects of socioeconomic inequality gender disparities on mental health. Future research could further explore the causal relationships that might exist between social factors and mental health outcomes. Currently, the global burden of disease database lack country level data for mental health for majority countries 81 . The data at the country level for the global burden of disease study could further improve our understanding the association between socioeconomic determinants and mental health.
The findings presented here provided strong evidence of a relationship between high gender inequality and a higher ratio of depressive disorder rates for both females and males. This significant correlation might be partially explained by gender discrimination. Gender prejudice, either overt or covert, could subject females to the experience of greater barriers to accessing community resources, including mental health care, that contribute to better health. The regions that exhibited high rates of common mental disorders also exhibited high levels of inequality, as reported by the WHO 6 . The United Nations emphasized the need for increased attention to factors that link gender disparities to health, including education, inclusion in policy decisions, participation, income, and differential socioeconomic status in its 17 sustainable development goals. It would be important to focus on the impact of policies designed to further equality, including both gender equality and wealth equality, in order to address existing mental health disparities and achieve the highest possible level of health for all people.

Eliminating racial health inequities requires a movement away from disparities as the focus of research and toward a research agenda centered on achieving equity by dismantling structural racism.
In order to help accomplish this task successfully, the objective of this study is to perform a systematic review of the most common topics and indicators used for measuring and monitoring health inequalities in the reports, projects, and databases of international, national, and regional governmental organizations.
We will likely look back on 2020 as a turning point. The pandemic put a spotlight on existing societal issues, accelerated the pace of change in others, and created some new ones too. For example, concerns about inequalities in health by income and race are not new, but they became more apparent to a larger number of people during 2020. The speed and starkness of broadening societal ...

Motivation for studying health inequalities. Despite considerable attention to the problem of health inequalities since the 1980s (), striking differences in health still exist among and within countries today ().In 2010, for example, Haitian men had a healthy life expectancy of 27.8 years, while men in Japan could expect 70.6 years, over twice as long, in full health ().
Kamila Hawthorne, chair of the Royal College of General Practioners Council, and Bola Owolabi, director of the National Healthcare Inequalities Improvement Programme, offer a personal perspective on how their professional experiences have led them to see health inequality as urgent priority, and introduce initiatives that can help general practitioners make a difference individually and ...
Discussion. This study demonstrated that social inequalities demonstrated a differential impact on mental health for females and males. For GII, greater gender inequality was significant (Model 1: 1.043, [1.034, 1.053]; P -value < 0.001) and related to the decreased gender disparity in depressive disorders.
