The impact of urbanization on mental health in India

Burden of depression in adolescents in the Western Pacific Region from 1990 to 2019: An age-period-cohort analysis of the Global Burden of Disease study

BACKGROUND

Depression is a highly prevalent and disabling mental health condition among adolescents. The epidemiology of depression in adolescents has been changing over time, reflecting changes in risk factors as well as disease concepts and diagnosis. However, few studies have characterized the longitudinal epidemiology of depression in adolescents. Understanding trends of disease burden provides key insights to improve resource allocation and design targeted interventions for this vulnerable population. The Western Pacific Region (WPR) is home to over 1.3 billion people with tremendous diversity in culture and socioeconomic development. The epidemiology of adolescent depression in WPR remains largely unknown. In this study, we aimed to estimate trends of disease burden attributable to depressive disorders among adolescents aged 10-24 years in WPR countries between 1990 and 2019, and to investigate period and cohort effects using the Global Burden of Disease (GBD) study database.

METHODS

The study utilized data from the Global Burden of Disease, Injuries, and Risk Factors Study 2019, concentrating on adolescents aged 10 to 24 years with depression. We conducted an in-depth analysis of depression, including its age-standardized prevalence, incidence, and Disability-Adjusted Life Years (DALYs), across diverse demographics such as regions, ages, genders, and socio-demographic indexes, spanning from 1990 to 2019.

RESULTS

The analysis found decreasing trends in the prevalence, incidence, and DALYs of adolescent depression in the WPR between 1990-2019, although some countries like Australia and Malaysia showed increases. Specifically, the prevalence of adolescent depression in the region decreased from 9,347,861.6 cases in 1990 to 5,551,341.1 cases in 2019. The incidence rate declined from 2,508.6 per 100,000 adolescents in 1990 to 1,947.9 per 100,000 in 2019. DALYs decreased from 371.9 per 100,000 in 1990 to ASR 299.7 per 100,000 in 2019.

CONCLUSION

This study found an overall decreasing trend in adolescent depression burden in the Western Pacific Region between 1990 and 2019, with heterogeneity across countries. For 30 years, the 20-24 age group accounted for the majority of depression among adolescents Widening inequality in depression burden requires policy attention. Further analysis of risk factors contributing to epidemiological trends is warranted to inform prevention strategies targeting adolescent mental health in the region.

Addressing Socioeconomic Determinants of Youth Suicidal Ideation: Lessons from a Youth Development Approach in India

Socioeconomic situations in young people's families and communities make them more vulnerable to suicidal ideations. The Youth Helpline has made a significant difference in youth's lives and livelihoods by addressing their social and economic needs with positive mental health support. The quantitative and qualitative data validate the micro- and macro-level impact of the Youth Helpline in Puducherry. However, the multi-stakeholder model faces challenges in ensuring accountability, particularly from government partners. This paper highlights how direct intervention on the socio-economic determinants of youth suicidal ideation has positively affected youth mental health and reduced suicidal ideation in Puducherry. Social identity-based inequalities and access and affordability to mental health services are the major contributors to youth mental health problems. This paper critically discusses the Youth Helpline's multi-stakeholder process and youth-led approach to addressing socio-economic determinants, as well as the Helpline's impact on youth mental health.

Urban precarity and youth mental health: An interpretive scoping review of emerging approaches

Circumstances of living are key to shaping emotional and affective experiences, long term health, wellbeing and opportunities. In an era characterised by rapid urbanisation across the majority of the world, there is increasing interest in the interaction between mental health and urban environments, but insufficient attention is paid to how mental health is situated in space and time. Socio-economic inequalities are prevalent in many urban environments globally, making conditions of living highly precarious for some social groups including young people. There remains a large volume of unmet mental health service needs, and young people are impacted by uncertain economic futures. The purpose of this scoping review is to develop an interdisciplinary and globally-informed understanding of the urban conditions which affect youth mental health across a range of scales, and to identify protective factors which can promote better youth mental health. We seek to broaden the scope of urban mental health research beyond the physical features of urban environments to develop an interpretive framework based on perspectives shared by young people. We illustrate how concepts from social theory can be used as an integrative framework to emphasise both young people's lived experiences and the wider cultural and political dynamics of urban mental health.

Risk of eating disorders and the relationship with interest in modern culture among young female students in a university in Bangladesh: a cross-sectional study

BACKGROUND

Eating disorders (EDs) emerge most often in adolescent girls. While the basic neural and psychiatric mechanisms of ED development remain unknown, their incidence has increased with sociocultural modernization. To determine what aspects of modern culture are related to EDs, we examined the relationship between predisposition to EDs and interest in several modern cultural factors among young female university students in Bangladesh.

METHODS

A cross-sectional study was conducted in a population of 196 female students aged 18-29 years in a university in Bangladesh. Their predisposition to EDs was examined using the Eating Attitudes Test-26 (EAT-26), and their interest in modern culture was evaluated by grading interest in fashionable clothes, Indian TV shows/serials, luxury food and social network activities, and by examining involvement in cultural activities such as playing, dancing, parties and singing. The relationship between predisposition to EDs and interest in modern culture was then examined. The relation between EAT-26 score and body mass index (BMI) was also examined.

RESULTS

The EAT-26 revealed that 37% of the participants were at risk of developing an ED. Correlation analyses showed that a high EAT-26 score was correlated with a high interest in fashionable clothes and Indian TV shows/serials, but not with a high interest in luxury food or social network activities, or involvement in cultural activities, such as playing, dancing, parties and singing. Further, EAT-26 questions in the dieting category and oral control category, but not the bulimia and food preoccupation category, were correlated with interest in cultural factors. EAT-26 score showed no significant correlation with BMI.

CONCLUSIONS

The results of this study indicate that the risk of EDs is related to an interest in several facets of modern culture. Monitoring the cultural interests of adolescent females, who are continually exposed to modern culture and highly susceptible to EDs, will contribute to the prevention of EDs.

COVID-19, adversities and depression among older adolescents in urban slums of India

PURPOSE

We report findings from a survey on the mental health impact of COVID-19 factoring environmental adversities among older adolescents (15-19 years) living in urban slums in India.

METHODS

We report survey results of 3490 older adolescents. Patient Health Questionnaire-9 was used to assess depression, slum adversity questionnaire for slum conditions, and for COVID-19 infection we recorded self-reported positivity status. Sociodemographic details were also collected. Additional sub-group analyses of sample who had depression and tested positive for COVID-19 infection was conducted. We used univariate and multivariate logistic regression models to identify factors and COVID-19 infection that were associated with depression.

RESULTS

Adolescents with adversities were three times more likely to report depression. Adolescents who reported COVID-19 infection were about two times more likely to have depression. Sub-group analyses showed that adolescents having experienced adversities and girls were more likely to report depression following COVID-19 infection.

CONCLUSIONS

There is a need for an intersectional research framework that incorporates stress arising out of a pandemic, social disadvantage, and systemic inequities. Such a framework will help to assess mental health issues of developmentally vulnerable groups residing in disadvantageous conditions.

Two Different Mismatches: Integrating the Developmental and the Evolutionary-Mismatch Hypothesis

Evolutionary psychology aims to understand the origins of the human mind, including disease. Several theories about the origins of disease have been proposed. One concerns a developmental mismatch—a mismatch might occur at the individual level between the environment experienced during childhood and the environment the adult finds herself in, possibly resulting in disease. A second theory concerns the idea of an evolutionary mismatch—humans are adapted to ancestral conditions so they might now experience a mismatch with their modern environment, possibly resulting in disease. A third theory—differential susceptibility—outlines how genetic and epigenetic differences influence the extent to which humans are susceptible to rearing, including positive and negative experiences. Because of these differences, some individuals are more prone to develop disease than others. We review empirical studies that substantiate these theories and argue that an overarching theory that integrates these three lines into one provides a more accurate understanding of disease from an evolutionary perspective.

Smoking, Health Risks, Coping Mechanisms and Depression in the age of COVID-19: a cross-sectional study of the Lebanese Population

Introduction

We compared depression of people who smoke and those who do not, depending on whether they have an underlying disease making them at risk for COVID-19. Moreover, we analyzed the factors associated with their depression.

Methods

We recruited 948 Lebanese residents, ages 18 and above. Our survey included the Patient Health Questionnaire-9 (PHQ-9) to assess depression. We divided participants, based on smoking and having a disease making one at risk for a COVID19 infection into four groups: non-smokers not at risk (NSNR), non-smokers at risk (NSR), smokers not at risk (SNR), and smokers at risk (SR).

Results

SR had PHQ-9 scores higher than other groups. The diet was not changed during the pandemic, whereas weight increased in all groups but SR. Those not at risk slept longer, while sports were decreased in NSR and SNR. Hobbies were decreased in all groups except SNR. Depending on the group, factors such as age, sex, residency, diet, exercise, sleep duration, and hobbies were associated with PHQ-9 scores.

Limitations

we cannot draw causal relationships. Participation required internet access, and participants might not represent the actual population due to the snowball effect. Also, recall bias might skew results. We did not inquire about sexual activity, which could be an essential coping mechanism.

Conclusion

Factors associated with depression for one group did not necessarily do so for another. Controlling the underlying risk or smoking cessation could move a patient to a group with more options associated with depression, thereby additional methods to decrease depression.

Sociodemographic and cultural determinants of mood disorders

PURPOSE OF REVIEW

The present review aims to examine, summarize and update information on the sociodemographic and cultural determinants of mood disorders.

RECENT FINDINGS

Known sociodemographic and cultural determinants continue to be good predictors of the risk of developing a mood disorder over the lifetime. Polygenic risk scores do not appear to offer any advantages over these determinants at present. There is also new and emerging understanding of the role of lifestyle and environmental factors in mediating vulnerability to mood disorder. The influence of ethnicity and migration, on the other hand, is far more complex than initially envisaged.

SUMMARY

Recent evidence on sociodemographic determinants of mood disorders confirms associations derived from existing literature. There is also new and emerging evidence on how quality of sleep, diet and the environment influence risk of mood disorders. Culture and ethnicity, depending on context, may contribute to both vulnerability and resilience. Socioeconomic deprivation may be the final common pathway through which several sociodemographic and cultural determinants of mood disorders act.

Phenotyping mental health: Age, community size, and depression differently modulate COVID-19-related fear and generalized anxiety

INTRODUCTION

When the first COVID-19 infections were reported in Germany, fear and anxiety spread faster than the pandemic itself. While moderate amounts of fear of a COVID-19 infection may be functional, generalized anxiety and the potentially resulting distress and psychopathology may possibly be detrimental to people's health. Authorities need to avoid a countrywide panic, on the one hand, but foster a realistic awareness of the actual threat, on the other hand.

OBJECTIVES

The current cross-sectional study aimed to investigate psychological reactions in response to the real or perceived infection threats. In particular, the analysis should reveal whether COVID-19-related fear and generalized anxiety in times of COVID-19 have distinct correlates.

METHODS

A nationwide study was conducted from March 10th to May 4th 2020 in Germany (n = 15,308; 10,824 women, 4433 men, 51 other). Generalized anxiety was assessed using the GAD-7, while COVID-19-related fear was measured using a self-generated item. Both outcome variables were entered into linear regression models. Demographic information, depressive symptoms, trust in governmental interventions, subjective level of information regarding COVID-19 and media use were used to predict generalized anxiety and COVID-19-related fear.

RESULTS

The data revealed distinct correlates of COVID-19-related fear and generalized anxiety. Although COVID-19-related fear and generalized anxiety had overlapping predictors, such as neuroticism, they most prominently differed in age distribution and direction of an urban-rural disparity: generalized anxiety decreases with age, but COVID-19-related fear is most pronounced in elderly participants. Generalized anxiety is also more prevalent in rural communities, but COVID-19-related fear is elevated in metropoles. Furthermore, the presence of a risk disease increases COVID-19-related fear, but not generalized anxiety.

CONCLUSION

These results suggest that COVID-19-related fear is often justified considering the individual risk of infection or complication due to infection. Some of the characteristics that predict COVID-19-related fear leave generalized anxiety unaffected or show divergent predictive directions. The present findings hint toward two related, but discriminant constructs.

Factors associated with psychological distress during the coronavirus disease 2019 (COVID-19) pandemic on the predominantly general population: A systematic review and meta-analysis

BACKGROUND

The Coronavirus Disease 2019 (COVID-19) outbreak has escalated the burden of psychological distress. We aimed to evaluate factors associated with psychological distress among the predominantly general population during the COVID-19 pandemic.

METHODS

We searched PubMed, EMBASE, Scopus, Cochrane Library, PsycINFO, and World Health Organization COVID-19 databases (Dec 2019-15 July 2020). We included cross-sectional studies that reported factors associated with psychological distress during the COVID-19 pandemic. Primary outcomes were self-reported symptoms of anxiety and depression. Random-effects models were used to pool odds ratios (OR) and 95% confidence intervals (CI). The protocol was registered in PROSPERO (#CRD42020186735).

FINDINGS

We included 68 studies comprising 288,830 participants from 19 countries. The prevalence of anxiety and depression was 33% (95% CI: 28%-39%) and 30% (26%-36%). Women versus men (OR: 1.48 [95% CI: 1.29-1.71; I2 = 90.8%]), younger versus older (< versus ≥35 years) adults (1.20 [1.13-1.26]; I2 = 91.7%), living in rural versus urban areas (1.13 [1.00-1.29]; I2 = 82.9%), lower versus higher socioeconomic status (e.g. lower versus higher income: 1.45 [1.24-1.69; I2 = 82.3%]) were associated with higher anxiety odds. These factors (except for residential area) were also associated with higher depression odds. Furthermore, higher COVID-19 infection risk (suspected/confirmed cases, living in hard-hit areas, having pre-existing physical or mental conditions) and longer media exposure were associated with higher odds of anxiety and depression.

INTERPRETATION

One in three adults in the predominantly general population have COVID-19 related psychological distress. Concerted efforts are urgently needed for interventions in high-risk populations to reduce urban-rural, socioeconomic and gender disparities in COVID-19 related psychological distress.

Stigma associated with mental health problems among young people in India: a systematic review of magnitude, manifestations and recommendations

BACKGROUND

Globally, 20% of young people experience mental disorders. In India, only 7.3% of its 365 million youth report such problems. Although public stigma associated with mental health problems particularly affects help-seeking among young people, the extent of stigma among young people in India is unknown. Describing and characterizing public stigma among young people will inform targeted interventions to address such stigma in India, and globally. Thus, we examined the magnitude and manifestations of public stigma, and synthesised evidence of recommendations to reduce mental-health-related stigma among young people in India.

METHOD

A systematic review and meta-analysis of observational studies was conducted. Nine electronic databases were searched and 30 studies (n = 6767) met inclusion criteria.

RESULTS

Most studies (66%) focused on youth training to become health professionals. One-third of young people display poor knowledge of mental health problems and negative attitudes towards people with mental health problems and one in five had actual/intended stigmatizing behavior (I2>=95%). Young people are unable to recognize causes and symptoms of mental health problems and believe that recovery is unlikely. People with mental health problems are perceived as dangerous and irresponsible, likely due to misinformation and misunderstanding of mental health problems as being solely comprised of severe mental disorders (e.g. schizophrenia). However, psychiatric labels are not commonly used/understood.

CONCLUSION

Public education may use symptomatic vignettes (through relatable language and visuals) instead of psychiatric labels to improve young people's understanding of the range of mental health problems. Recommended strategies to reduce public stigma include awareness campaigns integrated with educational institutions and content relevant to culture and age-appropriate social roles.

The burden of mental disorders across the states of India: the Global Burden of Disease Study 1990-2017

BACKGROUND

Mental disorders are among the leading causes of non-fatal disease burden in India, but a systematic understanding of their prevalence, disease burden, and risk factors is not readily available for each state of India. In this report, we describe the prevalence and disease burden of each mental disorder for the states of India, from 1990 to 2017.

METHODS

We used all accessible data from multiple sources to estimate the prevalence of mental disorders, years lived with disability (YLDs), and disability-adjusted life-years (DALYs) caused by these disorders for all the states of India from 1990 to 2017, as part of the Global Burden of Diseases, Injuries, and Risk Factors Study. We assessed the heterogeneity and time trends of mental disorders across the states of India. We grouped states on the basis of their Socio-demographic Index (SDI), which is a composite measure of per-capita income, mean education, and fertility rate in women younger than 25 years. We also assessed the association of major mental disorders with suicide deaths. We calculated 95% uncertainty intervals (UIs) for the point estimates.

FINDINGS

In 2017, 197·3 million (95% UI 178·4-216·4) people had mental disorders in India, including 45·7 million (42·4-49·8) with depressive disorders and 44·9 million (41·2-48·9) with anxiety disorders. We found a significant, but modest, correlation between the prevalence of depressive disorders and suicide death rate at the state level for females (r²=0·33, p=0·0009) and males (r²=0·19, p=0·015). The contribution of mental disorders to the total DALYs in India increased from 2·5% (2·0-3·1) in 1990 to 4·7% (3·7-5·6) in 2017. In 2017, depressive disorders contributed the most to the total mental disorders DALYs (33·8%, 29·5-38·5), followed by anxiety disorders (19·0%, 15·9-22·4), idiopathic developmental intellectual disability (IDID; 10·8%, 6·3-15·9), schizophrenia (9·8%, 7·7-12·4), bipolar disorder (6·9%, 4·9-9·6), conduct disorder (5·9%, 4·0-8·1), autism spectrum disorders (3·2%, 2·7-3·8), eating disorders (2·2%, 1·7-2·8), and attention-deficit hyperactivity disorder (ADHD; 0·3%, 0·2-0·5); other mental disorders comprised 8·0% (6·1-10·1) of DALYs. Almost all (>99·9%) of these DALYs were made up of YLDs. The DALY rate point estimates of mental disorders with onset predominantly in childhood and adolescence (IDID, conduct disorder, autism spectrum disorders, and ADHD) were higher in low SDI states than in middle SDI and high SDI states in 2017, whereas the trend was reversed for mental disorders that manifest predominantly during adulthood. Although the prevalence of mental disorders with onset in childhood and adolescence decreased in India from 1990 to 2017, with a stronger decrease in high SDI and middle SDI states than in low SDI states, the prevalence of mental disorders that manifest predominantly during adulthood increased during this period.

INTERPRETATION

One in seven Indians were affected by mental disorders of varying severity in 2017. The proportional contribution of mental disorders to the total disease burden in India has almost doubled since 1990. Substantial variations exist between states in the burden from different mental disorders and in their trends over time. These state-specific trends of each mental disorder reported here could guide appropriate policies and health system response to more effectively address the burden of mental disorders in India.

Is urban living good for mental health?

PURPOSE OF REVIEW

The questions of urban living, mental health and well-being are complex issues correlated to many interacting factors. The purpose of this review is to provide data on mental health challenges of urban life and perspectives to address these challenges.

RECENT FINDINGS

Urbanization may cause mental health problems, such as psychotic experiences, depression and stress-related disorders, particularly in vulnerable individuals. Challenges of urban living are even greater in developing countries, because of other urgent problems these countries are facing. New findings identified distinct neural mechanisms for an established environmental risk factor, linking the urban environment to social stress processing. Nature-based solutions may be helpful in preventing mental disorders and in alleviating psychological symptoms.

SUMMARY

The data of impact of urban living on mental health are still controversial and mechanism of association is unclear. Urban living may be related to biological or social/environmental factors or both. Most probably, urbanicity has a synergistic effect with genetic vulnerability. Interdisciplinary and intersectoral actions are needed to meet urban living challenges, such as providing access to green space and mental health services, decrease of poverty, homelessness and emerging problems of immigration to cities.

Pathways between urbanization and harmful substance use

PURPOSE OF REVIEW

Epidemiological literature suggests that urbanization is potentially linked to a number of stressors that could be associated with harmful substance use and mental disorders. This may vary by country. This review gives attention to emergent literature examining the pathways between urbanization and harmful substance use.

RECENT FINDINGS

Studies examining the links between urbanization, mental health and substance use suggest complex pathways between urbanization and substance use as well as a range of modifying variables that could contribute to these associations. Such variables include increased supply of illicit and licit substances brought about by economic development, globalization and technology as well as an increased demand for particular substances. Rural areas may also have unique factors associated with harmful substance use but these are beyond the scope of this review.

SUMMARY

We have presented evidence to suggest potential associations between urbanization and harmful substance use. We acknowledge that data are limited because of a paucity of longitudinal studies elucidating these relationships.
