Poverty, depression, and anxiety: Causal evidence and mechanisms

Economic uncertainty and mental health: Global evidence, 1991 to 2019

Mental health has deteriorated globally due to COVID-19, climate crisis, economic policies, and regional conflicts, requiring immediate attention. This study aims to comprehend the relationship between economic uncertainty and the prevalence of anxiety disorders, major depressive disorder, and eating disorders across various demographics and countries. Using robust fixed-effect models, we analyzed the relationship between economic uncertainty and mental disorders in 110 countries from 1991 to 2019. Our analysis also explored whether this association varies across genders and age groups. Our analysis indicates that economic uncertainty is associated with higher prevalence rates of anxiety and major depressive disorders, though no similar association is observed for eating disorders. In the subgroup analyses, while females have a significant association exclusively with anxiety disorders, males have associations with anxiety and major depressive disorders. The age-specific analyses show that economic uncertainty is associated with anxiety disorders for almost all age groups above 15 years, except for ages between 40 and 54. For major depressive disorders, this association becomes significant after the 40-44 age group. However, we see no significant association among age groups for eating disorders.

A meta-analytic examination of sensitive responsiveness as a mediator between depression in mothers and psychopathology in children

The current meta-analysis examined the mediating role of sensitive-responsive parenting in the relationship between depression in mothers and internalizing and externalizing behavior in children. A systematic review of the path of maternal sensitive responsiveness to child psychopathology identified eligible studies. Meta-analytic structural equation modelling (MASEM) allowed for the systematic examination of the magnitude of the indirect effect across 68 studies (N = 15,579) for internalizing and 92 studies (N = 26,218) for externalizing psychopathology. The synthesized sample included predominantly White, English-speaking children (age range = 1 to 205 months; Mage = 66 months; 47% female) from Western, industrialized countries. The indirect pathway was small in magnitude and similar for externalizing (b = .02) and internalizing psychopathology (b = .01). Moderator analyses found that the indirect pathway for externalizing problems was stronger when mother-child interactions were observed during naturalistic and free-play tasks rather than structured tasks. Other tested moderators were not significant.

Financial Literacy and Mental Health: Empirical Evidence from China

BACKGROUND AND OBJECTIVE

While financial literacy is a plausible determinant of mental health, there are relatively few studies exploring the relationship between financial literacy and mental health, and the existing literature focuses on a single construct of financial literacy in high-income settings. Our study addresses this by investigating whether there is an association between financial knowledge, attitudes, and behaviours and mental health in Chinese adults.

METHODS

We use data from the China Family Panel Studies, a nationally representative longitudinal survey. Mental health is measured using the Kessler Psychological Distress Scale (K6) and financial literacy is assessed using a unique module on financial literacy covering financial knowledge, financial attitudes and financial behaviours.

RESULTS

We found that overall financial literacy and two of its dimensions (financial attitudes and financial behaviours) are always positively associated with mental health. A positive association between basic financial knowledge and mental health is also apparent but is mediated by households' finances. Our results are robust to using different outcome variables and estimation methods. Finally, we found that compared with their counterparts without debt, indebted respondents show a stronger sensitivity of mental health to basic financial knowledge, as well as a significant association between advanced financial knowledge and mental health, which persist when we control for households' finances.

CONCLUSIONS

Our findings suggest that investments in financial education might significantly benefit mental health in Chinese adults. This is especially the case among indebted adults.

Low household income increases risks for chronic obstructive pulmonary disease in young population: a nationwide retrospective cohort study in South Korea

BACKGROUND

Low socioeconomic status is a risk factor for chronic obstructive pulmonary disease (COPD); however, the association between low household income and COPD in young populations remains unclear.

METHODS

We screened individuals aged 20-39 years who underwent the national health examination between 2009 and 2012 using the Korean National Health Information Database, which was searched until December 2019. We identified 5 965 366 eligible individuals, and 13 296 had newly developed COPD based on health insurance claims. We evaluated household income levels based on the health insurance premiums, categorised them into quartiles and 'Medical aid' (the lowest 3% income group), and assessed the annual income status from the preceding 4 years. Multivariate Cox proportional hazard models were used to estimate the adjusted HR (aHR) of risk factors for COPD.

RESULTS

In the Medical aid group, the incidence rate for developing COPD was 0.56/1000 person-years, with an aHR of 2.45 (95% CI 1.91 to 3.13) compared with that of the highest income quartile group. This association was prominent in consecutive recipients of Medical aid (aHR 2.37, 95% CI 1.80 to 3.11) compared with those who had never been Medical aid beneficiaries. Those who experienced a decline in household income between the previous (preceding 4 years) and baseline time points had an increased risk of developing COPD, regardless of previous income status.

CONCLUSION

Low household income was associated with an increased risk of developing COPD in the young population. This risk was augmented by sustained low income and declining income status.

Effect of Cash Benefits on Health Care Utilization and Health: A Randomized Study

Importance

Poverty is associated with greater barriers to health care and worse health outcomes, but it remains unclear whether income support can improve health.

Objective

To examine the effect of cash benefits on health care utilization and health.

Design, Setting, and Participants

The City of Chelsea, Massachusetts, a low-income community near Boston, randomly assigned individuals by lottery to receive cash benefits. Participants' medical records were linked across multiple health systems. Outcomes were assessed during the intervention period from November 24, 2020, to August 31, 2021.

Intervention

Cash benefits via debit card of up to $400 per month for 9 months.

Main Outcomes and Measures

The primary outcome was emergency department visits. Secondary outcomes included specific types of emergency department visits, outpatient use overall and by specialty, COVID-19 vaccination, and biomarkers such as cholesterol levels.

Results

Among 2880 individuals who applied for the lottery, mean age was 45.1 years and 77% were female. The 1746 participants randomized to receive the cash benefits had significantly fewer emergency department visits compared with the control group (217.1 vs 317.5 emergency department visits per 1000 persons; adjusted difference, -87.0 per 1000 persons [95% CI, -160.2 to -13.8]). This included reductions in emergency department visits related to behavioral health (-21.6 visits per 1000 persons [95% CI, -40.2 to -3.1]) and substance use (-12.8 visits per 1000 persons [95% CI, -25.0 to -0.6]) as well as those that resulted in a hospitalization (-27.3 visits per 1000 persons [95% CI, -53.6 to -1.1]). The cash benefit had no statistically significant effect on total outpatient visits (424.3 visits per 1000 persons [95% CI, -118.6 to 967.2]), visits to primary care (-90.4 visits per 1000 persons [95% CI, -308.1 to 127.2]), or outpatient behavioral health (83.5 visits per 1000 persons [95% CI, -182.9 to 349.9]). Outpatient visits to other subspecialties were higher in the cash benefit group compared with the control group (303.1 visits per 1000 persons [95% CI, 32.9 to 573.2]), particularly for individuals without a car. The cash benefit had no statistically significant effect on COVID-19 vaccination, blood pressure, body weight, glycated hemoglobin, or cholesterol level.

Conclusions and Relevance

In this randomized study, individuals who received a cash benefit had significantly fewer emergency department visits, including those related to behavioral health and substance use, fewer admissions to the hospital from the emergency department, and increased use of outpatient subspecialty care. Study results suggest that policies that seek to alleviate poverty by providing income support may have important benefits for health and access to care.

Stability and change in maternal wellbeing and illbeing from pregnancy to three years postpartum

PURPOSE

Motherhood affects women's mental health, encompassing aspects of both wellbeing and illbeing. This study investigated stability and change in wellbeing (i.e., relationship satisfaction and positive affect) and illbeing (i.e., depressive and anxiety symptoms) from pregnancy to three years postpartum. We further investigated the mutual and dynamic relations between these constructs over time and the role of genetic propensities in their time-invariant stability.

DATA AND METHODS

This four-wave longitudinal study included 83,124 women from the Norwegian Mother, Father, and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. Data were collected during pregnancy (30 weeks) and at 6, 18 and 36 months postpartum. Wellbeing and illbeing were based on the Relationship Satisfaction Scale, the Differential Emotions Scale and Hopkins Symptoms Checklist-8. Genetics were measured by the wellbeing spectrum polygenic index. Analyses were based on random intercept cross-lagged panel models using R.

RESULTS

All four outcomes showed high stability and were mutually interconnected over time, with abundant cross-lagged predictions. The period of greatest instability was from pregnancy to 6 months postpartum, followed by increasing stability. Prenatal relationship satisfaction played a crucial role in maternal mental health postpartum. Women's genetic propensity to wellbeing contributed to time-invariant stability of all four constructs.

CONCLUSION

Understanding the mutual relationship between different aspects of wellbeing and illbeing allows for identifying potential targets for health promotion interventions. Time-invariant stability was partially explained by genetics. Maternal wellbeing and illbeing develop in an interdependent way from pregnancy to 36 months postpartum.

Investigating the impact of poverty on mental illness in the UK Biobank using Mendelian randomization

It is unclear whether poverty and mental illness are causally related. Using UK Biobank and Psychiatric Genomic Consortium data, we examined evidence of causal links between poverty and nine mental illnesses (attention deficit and hyperactivity disorder (ADHD), anorexia nervosa, anxiety disorder, autism spectrum disorder, bipolar disorder, major depressive disorder, obsessive-compulsive disorder, post-traumatic stress disorder and schizophrenia). We applied genomic structural equation modelling to derive a poverty common factor from household income, occupational income and social deprivation. Then, using Mendelian randomization, we found evidence that schizophrenia and ADHD causally contribute to poverty, while poverty contributes to major depressive disorder and schizophrenia but decreases the risk of anorexia nervosa. Poverty may also contribute to ADHD, albeit with uncertainty due to unbalanced pleiotropy. The effects of poverty were reduced by approximately 30% when we adjusted for cognitive ability. Further investigations of the bidirectional relationships between poverty and mental illness are warranted, as they may inform efforts to improve mental health for all.

The causal effect of mental health on labor market outcomes: The case of stress-related mental disorders following a human-made disaster

As disasters increase due to climate change, population density, epidemics, and technology, information is needed about postdisaster consequences for people's mental health and how stress-related mental disorders affect multiple spheres of life, including labor-market attachment. We tested the causal hypothesis that individuals who developed stress-related mental disorders as a consequence of their disaster exposure experienced subsequent weak labor-market attachment and poor work-related outcomes. We leveraged a natural experiment in an instrumental variables model, studying a 2004 fireworks factory explosion disaster that precipitated the onset of stress-related disorders (posttraumatic stress disorder, anxiety, and depression) among individuals in the local community (N = 86,726). We measured labor-market outcomes using longitudinal population-level administrative data: sick leave, unemployment benefits, early retirement pension, and income from wages from 2007 to 2010. We found that individuals who developed a stress-related disorder after the disaster were likely to go on sickness benefit, both in the short- and long-term, were likely to use unemployment benefits and to lose wage income in the long term. Stress-related disorders did not increase the likelihood of early retirement. The natural experiment design minimized the possibility that omitted confounders biased these effects of mental health on work outcomes. Addressing the mental health and employment needs of survivors after a traumatic experience may improve their labor-market outcomes and their nations' economic outputs.

The mediating role of community identity in the relationship between social class and life satisfaction: Evidence from Chinese community residents

Research has shown that social class is an important predictor of life satisfaction. However, the underlying mechanism for this relationship is yet to be fully elucidated. The study examined the underlying mechanism based on the social identity approach to health. Study 1 recruited 577 community residents to complete self-report questionnaires. Correlation analysis showed that social class, community identity, and life satisfaction were positively correlated with each other. Regression analysis showed that community identity mediated the relationship. To increase the replicability and derive causal inference of the results, Study 2 was a randomized control trial (N = 76) that used the resource-availability task to manipulate subjective social class, and found that life satisfaction in the lower-class group was significantly lower than that in the control group. Further analysis showed that social class predicted life satisfaction through the mediating role of community identity. The findings provide potential strategies to enhance community residents' life satisfaction.

Impacts of Poverty and Lifestyles on Mortality: A Cohort Study in Predominantly Low-Income Americans

INTRODUCTION

Low socioeconomic status has been linked to increased mortality. However, the impacts of poverty, alone or combined with health behaviors, on mortality and life expectancy have not been adequately investigated.

METHODS

Data from the Southern Community Cohort Study was used, including nearly 86,000 participants recruited during 2002-2009 across 12 US southeastern states. Analysis was conducted from February 2022 to January 2023.

RESULTS

During a median follow-up of 12.1 years, 19,749 deaths were identified. A strong dose-response relationship was found between household incomes and mortality, with a 3.3-fold (95%CI=3.1-3.6) increased all-cause mortality observed for individuals in the lowest income group (<$15,000/year) compared with those in the highest group (≥$50,000/year). Within each income group, mortality monotonically increased with declining healthy lifestyle score. Risk was significantly lower among those in the lowest income but healthiest lifestyle group, compared to those with the highest income but unhealthiest lifestyle (HR=0.82, 95%CI=0.69-0.97). Poor White participants appeared to experience higher all-cause mortality than poor Black participants. Life expectancy was more than 10.0 years shorter for those in the lowest income group compared with those in the highest income group.

CONCLUSIONS

Poverty is strongly associated with increased risk of death, but the risks could be modestly abated by a healthier lifestyle. These findings call for a comprehensive strategy for enhancing a healthy lifestyle and improving income equality to reduce death risks, particularly among those experiencing health disparities due to poverty.

Does environmental pollution reduce residents' income? Evidence from CFPS in China

Understanding the relationship between environmental pollution and residents' income is extremely important for promoting sustained progress and high-quality economic growth. This research examines the impact, mechanism, and heterogeneity of environmental contamination on residents' earnings by fusing the micro data from China Family Panel Survey with the macro data of government statistics. The results reveal that environmental degradation has a significantly negative impact on residents' individual income. Further research on the intermediary mechanism finds that environmental pollution plays a harmful role in residents' income by reducing residents' subjective well-being and labor employment. Besides, the income effect of environmental pollution is significantly heterogeneous among different regions and differentiated groups. The deteriorating environmental quality widens urban-rural income gap and increases wage inequality of inhabitants in eastern, central, and western regions of China. The gender income gap and the income disparity between different income brackets also expand with environmental deterioration. These findings not only prove that long-term development at the cost of the ecological environment is undesirable, but also demonstrate the important role of the improvement of ecological environmental quality in promoting human well-being.

Mental COP: Mental Health Cohort Of Police officers in Korea

PURPOSE

This cohort study addresses the need for comprehensive and longitudinal research on police officers' mental health, focusing on the relationship between occupational factors, individual characteristics and mental health status or suicidality. The Mental COP (Mental health Cohort Of Police officers in Korea) research provides important insights by tracking new police officers over time, contributing to evidence-based interventions and policies to improve their overall mental health and working conditions.

PARTICIPANTS

Mental Cop is a prospective open cohort study designed for new police officers for police recruitment, expected to graduate after 8 months of education at the Central Police Academy. To date, 6752 individuals have completed the baseline survey and are enrolled in the cohort.

FINDING TO DATE

The study data in Mental COP covered a wide range of issues for first responders, including personal factors, various mental health problems, occupational factors and measured biomarkers of allostatic load, including Heart Rate Variability. The main findings indicate a lower prevalence of mental health problems among those selected as new police officers compared with the general population with notable gender differences. Therefore, closer monitoring of women is required. Furthermore, the study revealed cohort-based differences in mental health, highlighting increased risk related to occupational factors (field training) and the management of vulnerable groups.

FUTURE PLANS

Another wave of Mental COP is scheduled for December 2023, with plans for future cohort expansion. Additionally, it will establish a more comprehensive and systematic scientific framework for future investigations by integrating broader medical examinations and National Health Insurance Service Data.

Breast cancer symptom profile longitudinal changes: data mining study

OBJECTIVES

Identifying stable co-occurring symptoms in breast cancer (BC) patients during chemotherapy can improve symptom management and the treatment process. This study examines symptom cluster stability in Iranian BC patients receiving chemotherapy and evaluates stability across three-time points within each cluster.

METHODS

This study collected data from three-time points: initial chemotherapy commencement, 2½ months postdiagnosis, and 5 months postdiagnosis. The research used exploratory factor analysis (EFA) in combination with hierarchical cluster analysis (HCA) and K means clustering to address research questions.

RESULTS

In the initial clustering step, EFA identified five clusters with high consistency across three-time points. The first cluster showed depression, anxiety and irritability, while the second cluster was characterised by sexual interest and pain. The third cluster was associated with diarrhoea and vomiting. In the second step, we obtained the HCA item output and two clusters of K means clustering that recorded depression and anxiety symptoms over time. Vomiting, dry mouth, sexual interest, worrying and numbness were observed during the first and second points, but the frequency has decreased since then.

CONCLUSIONS

Cancer's psychological and physiological symptoms, including depression, anxiety, digestive and hormonal issues, remain stable throughout the disease. Palliative care centres can improve patients' quality of life and treatment process by addressing persistent symptoms.

Mendelian randomization evidence for the causal effect of mental well-being on healthy aging

Mental well-being relates to multitudinous lifestyle behaviours and morbidities and underpins healthy aging. Thus far, causal evidence on whether and in what pattern mental well-being impacts healthy aging and the underlying mediating pathways is unknown. Applying genetic instruments of the well-being spectrum and its four dimensions including life satisfaction, positive affect, neuroticism and depressive symptoms (n = 80,852 to 2,370,390), we performed two-sample Mendelian randomization analyses to estimate the causal effect of mental well-being on the genetically independent phenotype of aging (aging-GIP), a robust and representative aging phenotype, and its components including resilience, self-rated health, healthspan, parental lifespan and longevity (n = 36,745 to 1,012,240). Analyses were adjusted for income, education and occupation. All the data were from the largest available genome-wide association studies in populations of European descent. Better mental well-being spectrum (each one Z-score higher) was causally associated with a higher aging-GIP (β [95% confidence interval (CI)] in different models ranging from 1.00 [0.82-1.18] to 1.07 [0.91-1.24] standard deviations (s.d.)) independent of socioeconomic indicators. Similar association patterns were seen for resilience (β [95% CI] ranging from 0.97 [0.82-1.12] to 1.04 [0.91-1.17] s.d.), self-rated health (0.61 [0.43-0.79] to 0.76 [0.59-0.93] points), healthspan (odds ratio [95% CI] ranging from 1.23 [1.02-1.48] to 1.35 [1.11-1.65]) and parental lifespan (1.77 [0.010-3.54] to 2.95 [1.13-4.76] years). Two-step Mendelian randomization mediation analyses identified 33 out of 106 candidates as mediators between the well-being spectrum and the aging-GIP: mainly lifestyles (for example, TV watching and smoking), behaviours (for example, medication use) and diseases (for example, heart failure, attention-deficit hyperactivity disorder, stroke, coronary atherosclerosis and ischaemic heart disease), each exhibiting a mediation proportion of >5%. These findings underscore the importance of mental well-being in promoting healthy aging and inform preventive targets for bridging aging disparities attributable to suboptimal mental health.

Sociodemographic predictors of the association between self-reported sleep duration and depression

A growing interest has been recently reported in exploring sleep duration within psychology context in particular to its relation to some mental chronic diseases such as depression. The aim of this study is to investigate the association between self-reported sleep hours as an outcome and self-perceived depression among Emirati adults, after adjusting for sociodemographic factors such as age, gender, marital status, and employment status. We performed a cross-sectional analysis using 11,455 participants baseline data of the UAE Healthy Future Study (UAEHFS). Univariate and multivariate logistic regression models were performed with self-reported sleep hours as an outcome. The predictors were the self-reported depression by measuring the PHQ-8 score, sociodemographic factors (age, gender, marital status, and employment status) Odds ratios with 95% confidence intervals (CI) were reported. In a sensitivity analysis, a multivariate imputation by chained equations (MICE) procedure was applied with classification and Regression Trees (CART) to impute missing values. Overall, 11,455 participants were included in the final analysis of this study. Participants' median age was 32.0 years (Interquartile-Range: 24.0, 39.0). There were 6,217 (54.3%) males included in this study. In total, 4,488 (63.6%) of the participants reported sleep duration of more than 7 hours. Statistically significant negative association was observed between the total PHQ-8 score as a measure for depression and binarized self-reported sleep, OR = 0.961 (95% CI: 0.948, 0.974). For one unit increase in age and BMI, the odds ratio of reporting shorter sleep was 0.979 (95% CI: 0.969, 0.990) and 0.987 (95% CI: 0.977, 0.998), respectively. The study findings indicate a correlation between self-reported depression and an increased probability of individuals reporting shorter self-perceived sleep durations especially when considering the sociodemographic factors as predictors. There was a variation in the effect of depression on sleep duration among different study groups. In particular, the association between reported sleep duration and reported depression, students and unemployed individuals have reported longer sleep hours as compared to employed participants. Also, married individuals reported a higher percentage of longer sleep duration as compared to single and unmarried ones when examined reported depression as a predictor to sleep duration. However, there was no gender differences in self-perceived sleep duration when associated with reported depression.

University Students' Financial Situation During COVID-19 and Anxiety and Depressive Symptoms: Results of the COVID-19 German Student Well-Being Study (C19 GSWS)

Background

The COVID-19 pandemic has had a major impact on students' financial situation as well as on their mental health.

Aim

To examine the reported change in the financial situation of German university students before and across two time points of the COVID-19 pandemic and to evaluate its associations with anxiety and depressive symptoms.

Methods

We used data from the cross-sectional COVID-19 German Student Well-being Study conducted at five German universities (N = 7203). Linear regression models were used to analyze associations between a reported change in financial situation and anxiety and depressive symptoms.

Results

Twenty-eight percent of the participants reported to have a worsened financial situation at the time of the survey compared to the time prior to the pandemic. A worsened financial situation at the time of the survey as compared to prior to the pandemic was associated with higher levels of anxiety and depressive symptoms reported in all three depression and anxiety scales [a 1.46 point increase on the CES-D 8 scale (95% confidence interval (CI): 1.19; 1.73), a 0.37-point increase in PHQ-2 (95% CI: 0.28; 0.46), and a 0.45-point increase in GAD-2 (95% CI: 0.35; 0.55)]. An improved financial situation, on the other hand, was associated with lower levels of anxiety and depressive symptoms. As for the second change, comparing the current financial situation with the situation during the first wave of the pandemic, the associations with anxiety and depressive symptoms were broadly similar.

Conclusion

Our findings suggest that students are a vulnerable population in need of mental and financial support during times of crisis. Future research is needed to obtain insights into potential long-term effects of the pandemic on students' mental health.

Prevalence of common mental disorders in southern Brazilian women: a comparison of two population-based studies (2003 vs. 2015)

PURPOSE

To investigate the prevalence and associated factors of common mental disorders (CMD) in women, and comparing them in two periods, 2003 and 2015.

METHODS

A comparative study was conducted between two surveys with representative samples of women aged 20-60 years residing in southern Brazil. The final sample included 988 and 987 women from the 2003 and 2015 surveys, respectively. The presence of CMD was assessed using the Self-Reporting Questionnaire (SRQ-20 ≥ 8) in both surveys. Poisson regression analysis was used to evaluate the associations between the outcome (CMD) and variables of interest.

RESULTS

The mean age of the participants was 38.5 ± 11.1 years (2003) and 40.3 ± 11.4 years (2015). In 2003, the prevalence of CMD was 33.4% (95%CI: 30.5-36.3) and in 2015, it was 33.7% (95%CI: 30.8-36.7). Over 12 years, no significant differences were observed in the prevalence of CMD, except for a reduction in the prevalence in women of color and physically active. After adjusting, the prevalence ratios of CMD in 2003 and 2015 remained associated with low family income, a higher number of pregnancies, and tobacco use.

CONCLUSIONS

This study showed a trend toward stability in the high prevalence of CMD among women.

Interventions targeting social determinants of mental disorders and the Sustainable Development Goals: a systematic review of reviews

Globally, mental disorders account for almost 20% of disease burden and there is growing evidence that mental disorders are socially determined. Tackling the United Nations Sustainable Development Goals (UN SDGs), which address social determinants of mental disorders, may be an effective way to reduce the global burden of mental disorders. We conducted a systematic review of reviews to examine the evidence base for interventions that map onto the UN SDGs and seek to improve mental health through targeting known social determinants of mental disorders. We included 101 reviews in the final review, covering demographic, economic, environmental events, neighborhood, and sociocultural domains. This review presents interventions with the strongest evidence base for the prevention of mental disorders and highlights synergies where addressing the UN SDGs can be beneficial for mental health.

Complex Intersections Between Adverse Childhood Experiences and Negative Life Events Impact the Phenome of Major Depression

Background

There is evidence that adverse childhood experiences (ACEs) and negative life events (NLEs) are associated with major depression (MDD).

Purpose

To determine whether ACEs affect all features of mild MDD, including suicidal tendencies, brooding, neuroticism, insomnia, cognitive deficits, severity of depression and anxiety, and cognitive deficits, and whether NLEs mediate these effects.

Sample of the Study and Methods

This study examines a cohort of 118 academic students, namely 74 students who satisfied the DSM-5-TR criteria for MDD and 44 normal control students. We assessed brooding, neuroticism, suicidal ideation and attempts, and the severity of depression, anxiety, insomnia, and the Stroop tests.

Results

One validated factor could be extracted from brooding, neuroticism, current suicidal behaviors, and the severity of depression, anxiety, and insomnia, labeled the phenome of depression. A large part of the variance in the phenome of depression (55.0%) was explained by the combined effects of self-, relationships, and academic-related NLEs in conjunction with ACEs, including family dysfunction and abuse and neglect (both physical and emotional). The latter ACEs significantly interacted (moderating effect) with NLEs to impact the depression phenome. Although sexual abuse did not have direct effects on the phenome, its effects were mediated by NLEs. We discovered that increased sexual abuse, physical and emotional abuse and neglect, and ACEs related to family dysfunction predicted 22.5% of the variance in NLEs. Up to 18.5% of the variance in the Stroop test scores was explained by sexual abuse and the phenome of depression. The latter mediated the effects of NLEs and abuse, neglect, and family dysfunction on the Stroop test scores.

Conclusion

Complex intersections between ACEs and NLEs impact the phenome of depression, which comprises neuroticism, brooding, suicidal tendencies, and the severity of insomnia, anxiety, and depression, while sexual abuse together with other ACEs and NLEs may impact cognitive interference inhibition.

Psychological and social interventions for the promotion of mental health in people living in low- and middle-income countries affected by humanitarian crises

BACKGROUND

Because of wars, conflicts, persecutions, human rights violations, and humanitarian crises, about 84 million people are forcibly displaced around the world; the great majority of them live in low- and middle-income countries (LMICs). People living in humanitarian settings are affected by a constellation of stressors that threaten their mental health. Psychosocial interventions for people affected by humanitarian crises may be helpful to promote positive aspects of mental health, such as mental well-being, psychosocial functioning, coping, and quality of life. Previous reviews have focused on treatment and mixed promotion and prevention interventions. In this review, we focused on promotion of positive aspects of mental health.

OBJECTIVES

To assess the effects of psychosocial interventions aimed at promoting mental health versus control conditions (no intervention, intervention as usual, or waiting list) in people living in LMICs affected by humanitarian crises.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, and seven other databases to January 2023. We also searched the World Health Organization's (WHO) International Clinical Trials Registry Platform and ClinicalTrials.gov to identify unpublished or ongoing studies, and checked the reference lists of relevant studies and reviews.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing psychosocial interventions versus control conditions (no intervention, intervention as usual, or waiting list) to promote positive aspects of mental health in adults and children living in LMICs affected by humanitarian crises. We excluded studies that enrolled participants based on a positive diagnosis of mental disorder (or based on a proxy of scoring above a cut-off score on a screening measure).

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were mental well-being, functioning, quality of life, resilience, coping, hope, and prosocial behaviour. The secondary outcome was acceptability, defined as the number of participants who dropped out of the trial for any reason. We used GRADE to assess the certainty of evidence for the outcomes of mental well-being, functioning, and prosocial behaviour.

MAIN RESULTS

We included 13 RCTs with 7917 participants. Nine RCTs were conducted on children/adolescents, and four on adults. All included interventions were delivered to groups of participants, mainly by paraprofessionals. Paraprofessional is defined as an individual who is not a mental or behavioural health service professional, but works at the first stage of contact with people who are seeking mental health care. Four RCTs were carried out in Lebanon; two in India; and single RCTs in the Democratic Republic of the Congo, Jordan, Haiti, Bosnia and Herzegovina, the occupied Palestinian Territories (oPT), Nepal, and Tanzania. The mean study duration was 18 weeks (minimum 10, maximum 32 weeks). Trials were generally funded by grants from academic institutions or non-governmental organisations. For children and adolescents, there was no clear difference between psychosocial interventions and control conditions in improving mental well-being and prosocial behaviour at study endpoint (mental well-being: standardised mean difference (SMD) 0.06, 95% confidence interval (CI) -0.17 to 0.29; 3 RCTs, 3378 participants; very low-certainty evidence; prosocial behaviour: SMD -0.25, 95% CI -0.60 to 0.10; 5 RCTs, 1633 participants; low-certainty evidence), or at medium-term follow-up (mental well-being: mean difference (MD) -0.70, 95% CI -2.39 to 0.99; 1 RCT, 258 participants; prosocial behaviour: SMD -0.48, 95% CI -1.80 to 0.83; 2 RCT, 483 participants; both very low-certainty evidence). Interventions may improve functioning (MD -2.18, 95% CI -3.86 to -0.50; 1 RCT, 183 participants), with sustained effects at follow-up (MD -3.33, 95% CI -5.03 to -1.63; 1 RCT, 183 participants), but evidence is very uncertain as the data came from one RCT (both very low-certainty evidence). Psychosocial interventions may improve mental well-being slightly in adults at study endpoint (SMD -0.29, 95% CI -0.44 to -0.14; 3 RCTs, 674 participants; low-certainty evidence), but they may have little to no effect at follow-up, as the evidence is uncertain and future RCTs might either confirm or disprove this finding. No RCTs measured the outcomes of functioning and prosocial behaviour in adults.

AUTHORS' CONCLUSIONS

To date, there is scant and inconclusive randomised evidence on the potential benefits of psychological and social interventions to promote mental health in people living in LMICs affected by humanitarian crises. Confidence in the findings is hampered by the scarcity of studies included in the review, the small number of participants analysed, the risk of bias in the studies, and the substantial level of heterogeneity. Evidence on the efficacy of interventions on positive mental health outcomes is too scant to determine firm practice and policy implications. This review has identified a large gap between what is known and what still needs to be addressed in the research area of mental health promotion in humanitarian settings.

Depression and associated factors among older people in Vietnam: Findings from a National Aging Survey

BACKGROUND

Depression is one of the most common mental health disorders among older people. Depressive symptoms are often overlooked and untreated in primary care settings. This study aims to assess the prevalence of depressive symptoms and associated factors among older people in Vietnam.

METHOD

The study analyzed data from the Vietnam National Aging Survey (VNAS) conducted in 2022 with a nationally representative sample of 3,006 older people aged 60 and over in 12 provinces. The 15-item Geriatric Depression Scale (GDS-15) was used to assess depressive symptoms. Bivariate and multiple logistic regression analyses were used to explore the association between depressive symptoms and other related factors such as sociodemographic and economic characteristics, social support, health status, Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) limitations, chronic diseases, cigarette smoking status, alcoholic drinking, and domestic violence.

RESULTS

The prevalence of depressive symptoms among older people was 20.2%. The associated factors that increase the odds of having depression among older people were female gender (OR = 2.21, 95% CI 1.34-3.62), living in rural areas (OR = 1.83, 95% CI 1.15-2.89), the poorest quintile (OR = 2.26, 95% CI 1.39-3.66), self-rated poor health (OR = 11.68, 95% CI 4.96-27.49), ADL limitations (OR = 2.12, 95% CI 1.51-2.99), IADL limitation (OR = 1.61 95% CI 1.16-2.25), and experiencing domestic violence in the last 12 months (OR = 6.66, 95% CI 4.00-11.05).

CONCLUSION

Depression symptoms were prevalent among older people in Vietnam. Depression screening for older people should be included in primary care settings for early identification and treatment of depression.

Cash transfers and mental health in Egypt

The relationship between poverty and mental health is complex. Conditional cash transfers are seen as an important policy tool in reducing poverty and fostering social protection. Evidence on the impact of cash transfers on mental health is mixed. In this study, we assess the causal impact of Egypt's conditional cash transfer (CCT) programme Takaful on the main recipients' mental health. Using a regression discontinuity design, we find that receiving the Takaful CCT does not have a significant impact on the anxiety levels of mothers in our sample. In addition, we do not find supporting evidence that the programme has heterogeneous impacts on anxiety levels. We discuss possible explanations behind these null results.

Comparing the World Psychiatric Association and European Psychiatric Association Codes of Ethics: Discrepancies and shared grounds

BACKGROUND

Codes of ethics provide guidance to address ethical challenges encountered in clinical practice. The harmonization of global, regional, and national codes of ethics is important to avoid gaps and discrepancies.

METHODS

We compare the European Psychiatric Association (EPA) and the World Psychiatric Association (WPA) Codes of Ethics, addressing main key points, similarities, and divergences.

RESULTS

The WPA and EPA codes are inspired by similar fundamental values but do show a few differences. The two codes have a different structure. The WPA code includes 4 sections and lists 5 overarching principles as the basis of psychiatrists' clinical practice; the EPA code is articulated in 8 sections, lists 4 ethical principles, and several fundamental values. The EPA code does not include a section on psychiatrists' education and does not contain specific references to domestic violence and death penalty. Differences can be found in how the two codes address the principle of equity: the EPA code explicitly refers to the principle of universal health care, while the WPA code mentions the principle of equity as reflected in the promotion of distributive justice.

CONCLUSIONS

We recommend that both WPA and EPA periodically update their ethical codes to minimize differences, eliminate gaps, and help member societies to develop or revise national codes in line with the principles of the associations they belong to.Minimizing differences between national and international codes and fostering a continuous dialogue on ethical issues will provide guidance for psychiatrists and will raise awareness of the importance of ethics in our profession.

The effect of outdoor activities on the medical expenditure of older people: multiple chain mediating effects of health benefits

BACKGROUND

With the global aging population, attention to the health and medical issues of older adults is increasing. By analyzing the relationship between older people's participation in outdoor activities and medical expenditure, this study aims to provide a scientific basis for improving their quality of life and reducing the medical burden.

METHODS

Data on outdoor activity participation, medical expenditures, and relevant variables were collected through questionnaires and databases. A multi-chain mediation effect model was established to analyze the impact of outdoor activities on the medical expenditure of older people, considering mediation effects and heterogeneity.

RESULTS

Results revealed that increased participation in outdoor activities among older adults correlated with lower medical expenditures. Outdoor activities positively influenced their health by improving mental health, cognition, eating habits, and activities of daily living, resulting in reduced medical expenditures. Robustness tests confirmed the consistent effect of outdoor activities on older people's medical expenditure.

CONCLUSION

These findings contribute to understanding the relationship between outdoor activities, health, and medical expenditure in older people, guiding policy formulation and interventions. Encouraging and supporting older adults in outdoor activities can enhance their quality of life and alleviate medical resource strain. The study's conclusions can also inform health promotion measures for other populations and serve as a basis for future research in this area.

Social determinants of mental health in major depressive disorder: Umbrella review of 26 meta-analyses and systematic reviews

There is a growing recognition of the impact of social determinants of mental health (SDoMHs) on people with, or at risk of, developing serious mental illnesses. Yet it is not known how associations of individual SDoMHs with risk for major depressive disorder (MDD) vary and roughly compare with one another. Following PRISMA guidelines, this umbrella review included 26 meta-analyses and systematic reviews that reported odds ratios, effect sizes, and/or pooled prevalence rates of MDD in samples with versus without specified SDoMHs. Childhood emotional, physical, or sexual abuse and neglect; intimate partner violence in females; and food insecurity were significantly associated with increased risk of MDD, with medium effect sizes. Natural disasters, terrorist acts, and military combat during deployment had small-size adverse effects, and homelessness, incarceration, and migration were associated with significantly elevated prevalence of MDD. Conversely, higher levels of parental care were significantly associated with reduced risk of MDD with medium effect sizes. Evidence supports the use of certain interventions at the individual and community level that can reduce the impact of these factors and promote health, although much more research is warranted in this area along with meaningful healthcare and societal policies to accomplish this goal.

The beneficial effect of fluoxetine on behavioral and cognitive changes in chronic experimental Chagas disease unveils the role of serotonin fueling astrocyte infection by Trypanosoma cruzi

BACKGROUND

In Chagas disease (CD), a neglected tropical disease caused by the parasite Trypanosoma cruzi, the development of mental disorders such as anxiety, depression, and memory loss may be underpinned by social, psychological, and biological stressors. Here, we investigated biological factors underlying behavioral changes in a preclinical model of CD.

METHODOLOGY/PRINCIPAL FINDINGS

In T. cruzi-infected C57BL/6 mice, a kinetic study (5 to 150 days postinfection, dpi) using standardized methods revealed a sequential onset of behavioral changes: reduced innate compulsive behavior, followed by anxiety and depressive-like behavior, ending with progressive memory impairments. Hence, T. cruzi-infected mice were treated (120 to 150 dpi) with 10 mg/Kg/day of the selective serotonin reuptake inhibitor fluoxetine (Fx), an antidepressant that favors neuroplasticity. Fx therapy reversed the innate compulsive behavior loss, anxiety, and depressive-like behavior while preventing or reversing memory deficits. Biochemical, histological, and parasitological analyses of the brain tissue showed increased levels of the neurotransmitters GABA/glutamate and lipid peroxidation products and decreased expression of brain-derived neurotrophic factor in the absence of neuroinflammation at 150 dpi. Fx therapy ameliorated the neurochemical changes and reduced parasite load in the brain tissue. Next, using the human U-87 MG astroglioma cell line, we found no direct effect of Fx on parasite load. Crucially, serotonin/5-HT (Ser/5-HT) promoted parasite uptake, an effect increased by prior stimulation with IFNγ and TNF but abrogated by Fx. Also, Fx blocked the cytokine-driven Ser/5-HT-promoted increase of nitric oxide and glutamate levels in infected cells.

CONCLUSION/SIGNIFICANCE

We bring the first evidence of a sequential onset of behavioral changes in T. cruzi-infected mice. Fx therapy improves behavioral and biological changes and parasite control in the brain tissue. Moreover, in the central nervous system, cytokine-driven Ser/5-HT consumption may favor parasite persistence, disrupting neurotransmitter balance and promoting a neurotoxic environment likely contributing to behavioral and cognitive disorders.

Latent profile analysis of depression in US adults with obstructive sleep apnea hypopnea syndrome

Objective

This study used latent profile analysis to explore the level of depression among US adults with obstructive sleep apnea hypopnea syndrome (OSAHS) symptoms and to identify different latent categories of depression to gain insight into the characteristic differences between these categories.

Methods

The data of this study were obtained from the National Health and Nutrition Examination Survey (NHANES) database, and the subjects with OSAHS symptoms were aged 18 years and older. The latent profile analysis (LPA) method was used to fit the latent depression categories in subjects with OSAHS symptoms. The chi-square test, rank sum test, and binary logistic regression were used to analyze the influencing factors of depression subgroups in subjects with OSAHS symptoms.

Results

Three latent profiles were identified: low-level (83.7%), moderate-level (14.5%) and high-level (1.8%) depression. The scores of 9 items in the high-level depression group were higher than those in the other two groups. Among them, item 4 "feeling tired or lack of energy" had the highest score in all categories.

Conclusion

Depression in subjects with OSAHS symptoms can be divided into low-level, moderate-level and high-level depression. There are significant differences among different levels of depression in gender, marital status, PIR, BMI, smoking, general health condition, sleep duration and OSAHS symptom severity.

Association between precarious employment and the onset of depressive symptoms in men and women: a 13-year longitudinal analysis in Korea (2009-2022)

AIMS

Increasing social concern surrounds the potential adverse health effects of precarious employment (PE). In this study, we explored the association between PE and the onset of depressive symptoms.

METHODS

A total of 11,555 Korean waged workers (5700 females) contributed 62,217 observations from 2009 to 2022. PE was operationalized as a multidimensional construct, including employment insecurity, income inadequacy and lack of rights and protection. Depressive symptoms were evaluated using the Center for Epidemiological Studies-Depression Scale (11-item version). The association between PE and the onset of depressive symptoms in the subsequent year was estimated using generalized estimating equations. Effect sizes were reported as odds ratio (OR) and 95% confidence interval (CI).

RESULTS

The overall incidence of depressive symptoms was 8.3% during the study period. In cross-sectional analysis, daily employment, disguised employment, lower monthly wages and lack of social insurance coverage were associated with concurrent depressive symptoms in both men and women. Longitudinally, fixed-term employment (OR: 1.17, 95% CI: 1.07-1.29), daily employment (OR: 1.64, 95% CI: 1.45-1.85) and disguised employment (OR: 1.36, 95% CI: 1.17-1.57) were associated with the onset of depressive symptoms among the overall sample. Among men, the lowest quartiles of wage were associated with the onset of depressive symptoms (OR: 1.34, 95% CI: 1.13-1.60), while the absence of a trade union was associated among women (OR: 1.18, 95% CI: 1.01-1.39).

CONCLUSIONS

Employment insecurity, inadequate income and lack of rights and protection may contribute to depressive symptoms. Therefore, PE serves as a significant social determinant of mental health among workers in Korea. Active policy efforts are warranted to improve the overall quality of employment in the workforce.

Mental health impacts of COVID-19: A retrospective analysis of dynamic modelling projections for Australia

Background

In early 2020, we developed a dynamic model to support policy responses aimed at mitigating the adverse mental health effects of the COVID-19 pandemic in Australia. As the pandemic has progressed, it has become clear that our initial model forecasts overestimated the impacts of infection control measures (lockdowns, physical distancing, etc.) on suicide, intentional self-harm hospitalisation, and mental health-related emergency department (ED) presentation rates.

Methods

Potential explanations for the divergence of our model predictions from observed outcomes were assessed by comparing simulation results for a set of progressively more refined models with data on the prevalence of moderate to very high psychological distress and numbers of suicides, intentional self-harm hospitalisations, and mental health-related ED presentations published after our modelling was released in July 2020.

Results

Allowing per capita rates of spontaneous recovery and intentional self-harm to differ between people experiencing moderate to very high psychological distress prior to the pandemic and those developing comparable levels of psychological distress only as a consequence of infection control measures substantially improves the fit of our model to empirical estimates of the prevalence of psychological distress and leads to significantly lower predicted effects of COVID-19 on suicide, intentional self-harm hospitalisation, and mental health-related ED presentation rates.

Conclusion

Accommodating the influence of prior mental health on the psychological effects of population-wide social and economic disruption is likely to be critical for accurately forecasting the mental health impacts of future public health crises as they inevitably arise.

Mental health among adolescents exposed to social inequality in Latin America and the Caribbean: a scoping review

Background and objective

Adolescents from Latin America and the Caribbean grow up in a context of social inequality, which diminishes their well-being and leads to impaired emotional-cognitive development. To understand the problem, it is important to synthesize the available research about it. This study aims to explore the knowledge about adolescents' mental health in Latin America and the Caribbean exposed to social inequality.

Methods

A systematic scoping review was conducted encompassing a search in five databases (Medline, CINAHL, PsycINFO, Scopus, and LILACS) in June 2022. Articles of various typologies were included without time limit. After two rounds of screening, relevant data were manually extracted and synthesized into self-constructed themes using thematic analysis.

Results

Out of 8,825 retrieved records, 42 papers were included in the final review, with a predominance of quantitative approaches. The synthesis revealed two main analytical themes: (a) defining social inequality, wherein intersecting inequalities produce discrimination and determine conditions for social vulnerability; (b) social inequality and mental health, which highlights the association between socio-structural difficulties and emotional problems, amplifying vulnerability to mental ill health and poor mental health care.

Conclusion

The scientific evidence reveals that social inequality is related to impaired well-being and mental ill health on the one hand and a lack of access to mental health care on the other hand.

Screening of Depression Among Medical Outpatients Visiting the University Teaching Hospital of Kigali, Rwanda

Background

Depression is a significant global public health concern, affecting individuals across different age groups and cultural backgrounds. However, screening for depression remains an essential but often neglected aspect of healthcare, particularly in outpatient settings. This study aimed to assess the prevalence of depression among outpatients visiting the internal medicine department of the University Teaching Hospital of Kigali in Rwanda and evaluate the feasibility of implementing a depression screening program in this setting.

Methods

An institution-based cross-sectional study design was employed, involving 300 adult medical outpatients through convenience sampling, aged 18 years and above, who visited the internal medicine department between October 7 to November 6, 2019. The Patient Health Questionnaire-9 (PHQ-9) was used as the screening tool to assess depressive symptoms. Additionally, socio-demographic and clinical data were collected to explore potential risk factors associated with depression using a binary logistic regression model.

Results

A high prevalence of depression was identified among internal medicine outpatients, with 45.7% of participants screened positive for depression, with moderate, moderately severe, and severe depression accounting for 21%, 17%, and 8%, respectively. The following factors were significantly associated with positive screening for depression: lack of formal education (OR=4.463, p=0.011, 95% CI= [1.410; 14.127]), secondary education (OR=3.402, p=0.003, 95% CI= [1.517; 7.630]), low-income (OR=2.392, p=0.049, 95% CI= [1.003; 5.706]) and headache as a chief complaint (OR=3.611, p=0.001, CI= [1.718; 7.591]).

Conclusion

This study highlights the high prevalence of depression among medical outpatients. Due to the stigma associated with mental health, patients frequently seek help for physical symptoms such as headaches and other bodily complaints rather than mental health concerns. Introducing routine depression screening in medical departments could potentially facilitate early identification, and intervention, and lead to improved patient care. Future research should focus on evaluating such screening programs' effectiveness and long-term outcomes in resource-limited settings like Rwanda.

The cost of inaction on health equity and its social determinants

Rising levels of inflation, debt and macrofiscal tightening are putting expenditures on the social sectors including health under immense scrutiny. Already, there are worrying signs of reductions in social sector investments. However, even before the pandemic, evidence showed the significant returns on investments in health equity and its social determinants. Emerging data and trends show that these potential returns have increased during the COVID-19 pandemic - investments in social determinants can mitigate widespread reductions in human capital and the increasing likelihood of costly syndemics, while promoting access to healthcare innovations that have thus far been inequitably distributed. Therefore, we argue that, despite immediate fiscal pressures, this is exactly the time to invest in health equity and its broader social determinants, as the returns on such investments have never been greater.

Relationship between social inequality perception patterns and depressive symptoms among Chinese adults: A national representative longitudinal study

BACKGROUND

The rising prevalence of depressive symptoms presents a pressing global public health concern, exacerbated by prevailing social inequality.

AIM

This study seeks to identify latent profiles of social inequality perception and explore their associations with depressive symptoms.

METHODS

Data were obtained from the China Family Panel Studies (CFPS) involving 10,529 residents aged 18 years and above. Latent profile analysis (LPA) was used to identify different patterns of social inequality perception. Multiple linear regression analysis examined the links between these patterns and depressive symptoms.

RESULTS

Three distinct patterns of social inequality perception were identified: the disappointed pattern (TDP), the neutral pattern (TNP), and the positive pattern (TPP). Perceived social inequality was significantly associated with short-term and long-term depressive symptoms (β = .51, 95% CI [0.29, 0.72] vs. β = .51, 95% CI [0.27, 0.74]). Increases in social inequality perception patterns were also related to more severe depressive symptoms (β = .55, 95% CI [0.36, 0.74]).

CONCLUSIONS

Increasing perceived social inequality is closely linked to elevated depressive symptoms in Chinese adults. This underscores the need for tailored strategies aimed at addressing heightened perceptions of social inequality to reduce the risk of depressive symptoms.

The changing psychiatry workforce in Australia: Still lacking in rural and remote regions

INTRODUCTION

There is a long standing and worsening shortage of psychiatrists in Australia particularly in rural areas. The majority of psychiatrists work in major cities.

OBJECTIVE

To identify recent trends in the Australian rural psychiatrist workforce compared with the metropolitan workforce.

DESIGN

We descriptively analysed population-level data from the National Health Workforce Data Set (NHWDS), the Australian Institute of Health and Welfare (AIHW) and the Australian Bureau of Statistics (ABS). A descriptive analysis of the numbers (count) and gender of psychiatrists from 1995 to 2022 working in Australia was conducted. For the period 2013 to 2022, we analysed for rurality, gender, years' experience, hours worked, Medicare-subsidised services provided and proportions of Specialist International Medical Graduates (SIMG) by sex, with a focus on the rural workforce. For international comparison, psychiatrist numbers were obtained for other OECD countries. The number of psychiatrists working in Australia, as per NHWDS and AIHW, was quantified. We analysed trends in demographics, hours worked and rurality of psychiatrists working in Australia in a serial cross-sectional design.

FINDINGS

Most psychiatrists are maldistributed to major cities, while outer regional and remote areas have few resident psychiatrists. Outer regional New South Wales (NSW) and South Australia (SA) have the lowest numbers of psychiatrists per capita. The full-time equivalent (FTE) of psychiatrists per 100 000 has increased from 12.6 in 2000 to 15.2 in 2022. However, the average hours worked by psychiatrists has declined. In total, available psychiatrist hours worked per 100 000 population has increased by 6.1% since the beginning of the millennium.

DISCUSSION

Rural areas in NSW and SA have the greatest shortage of psychiatrists. Specialist International Medical Graduates and females (43% of the overall workforce) are the predominant workforce in rural areas. Although Medicare-subsidised services per 1000 people have increased in rural areas, they remain lower than for those living in major cities.

CONCLUSION

There remains an acute shortage of psychiatrists in many regional and remote areas of Australia, with an increasing proportion of SIMGs and females working in these areas, in the context of future increased demand.

Anxiety and Depression in Pediatric-Onset Traumatic Spinal Cord Injury: A Systematic Review

BACKGROUND

Traumatic spinal cord injury (TSCI) is a debilitating neurological condition with significant long-term consequences on the mental health and well-being of affected individuals. We aimed to investigate anxiety and depression in individuals with pediatric-onset TSCI.

METHODS

PubMed, Scopus, and Web of Science databases were searched from inception to December 20th, 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, and studies were included according to the eligibility criteria.

RESULTS

A total of 1013 articles were screened, and 18 studies with 4234 individuals were included in the final review. Of these, 1613 individuals (38.1%) had paraplegia, whereas 1658 (39.2%) had tetraplegia. A total of 1831 participants (43.2%) had complete TSCI, whereas 1024 (24.2%) had incomplete TSCI. The most common etiology of TSCI with 1545 people (36.5%) was motor vehicle accidents. The youngest mean age at the time of injury was 5.92 ± 4.92 years, whereas the oldest was 14.6 ± 2.8 years. Patient Health Questionnaire-9 was the most common psychological assessment used in 9 studies (50.0%). Various risk factors, including pain in 4 studies (22.2%), reduced sleep quality, reduced functional independence, illicit drug use, incomplete injury, hospitalization, reduced quality of life, and duration of injury in 2 (11.1%) studies, each, were associated with elevated anxiety and depression.

CONCLUSIONS

Different biopsychosocial risk factors contribute to elevated rates of anxiety and depression among individuals with pediatric-onset TSCI. Individuals at risk of developing anxiety and depression should be identified, and targeted support should be provided. Future large-scale studies with long-term follow-up are required to validate and extend these findings.

The Intersectional Impact of Cost-Related Non-Adherence and Depression: A Cross-Sectional Analysis of the Canadian Community Health Survey by Sex, Race, and Indigeneity

We evaluated the relationship between cost-related non-adherence (CRNA) and depressive symptoms. Pooling data from the 2015, 2016, 2018, and 2019 annual Canadian Community Health Survey, we analyzed the relationship between CRNA and moderate to severe depressive symptoms, assessed by the Patient Health Questionnaire (PHQ-9). Among the sample, 4.9% experienced CRNA and 6.8% experienced moderate to severe depressive symptoms. Respondents who reported CRNA had 1.51 (95% confidence interval [CI], 1.51-1.52) greater odds of experiencing moderate to severe depressive symptoms. Stratified analysis by sex and race showed the association between CRNA and depressive symptoms was greatest among racialized males (aOR: 1.83, 95% CI: 1.81- 1.85). Stratified analysis by sex and Indigeneity showed this association was greatest for Indigenous males (aOR: 2.16, 95% CI: 2.10-2.22). Forgoing prescribed medications due to cost is associated with more severe depressive symptoms among Canadians, particularly racialized and Indigenous males.

The promise and pitfalls of a strength-based approach to child poverty and neurocognitive development: Implications for policy

There has been significant progress in understanding the effects of childhood poverty on neurocognitive development. This progress has captured the attention of policymakers and promoted progressive policy reform. However, the prevailing emphasis on the harms associated with childhood poverty may have inadvertently perpetuated a deficit-based narrative, focused on the presumed shortcomings of children and families in poverty. This focus can have unintended consequences for policy (e.g., overlooking strengths) as well as public discourse (e.g., focusing on individual rather than systemic factors). Here, we join scientists across disciplines in arguing for a more well-rounded, "strength-based" approach, which incorporates the positive and/or adaptive developmental responses to experiences of social disadvantage. Specifically, we first show the value of this approach in understanding normative brain development across diverse human environments. We then highlight its application to educational and social policy, explore pitfalls and ethical considerations, and offer practical solutions to conducting strength-based research responsibly. Our paper re-ignites old and recent calls for a strength-based paradigm shift, with a focus on its application to developmental cognitive neuroscience. We also offer a unique perspective from a new generation of early-career researchers engaged in this work, several of whom themselves have grown up in conditions of poverty. Ultimately, we argue that a balanced strength-based scientific approach will be essential to building more effective policies.

Polygenic risk for depression predicting temperament trajectories over 15 years - A general population study

BACKGROUND

A great number of case-control and population-based studies have shown that depression patients differ from healthy controls in their temperament traits. We investigated whether polygenic risk for depression predicts trajectories of temperament traits from early adulthood to middle age.

METHODS

Participants came from the population-based Young Finns Study (n = 2212). The calculation for Polygenic risk for depression (PRS) was based on the most recent genome-wide association study. Temperament traits of Harm Avoidance, Novelty Seeking, Reward Dependence, and Persistence were assessed with the Temperament and Character Inventory in 1997, 2001, 2007, and 2012 (participants being 24-50-year-olds). As covariates, we used depressive symptoms as assessed by a modified version of the Beck Depression Inventory, psychosocial family environment from parent-filled questionnaires, and socioeconomic factors from adulthood.

RESULTS

High PRS predicted higher Persistence from early adulthood to middle age (p = 0.003) when controlling for depressive symptoms, psychosocial family environment, and socioeconomic factors. PRS did not predict trajectories of Novelty Seeking (p = 0.063-0.416 in different models) or Reward Dependence (p = 0.531-0.736). The results remained unaffected when participants with diagnosed affective disorders were excluded. Additionally, we found an interaction between PRS and depressive symptoms when predicting the Harm Avoidance subscale Anticipatory Worry, indicating that the association of Anticipatory Worry with depressive symptoms is stronger in individuals with higher (vs. lower) PRS.

LIMITATIONS

There was some attrition due to the long follow-up.

CONCLUSIONS

High polygenic risk for major depression may predict differences in temperament trajectories among those who have not developed any severe affective disorders.

Assets and depression in U.S. adults during the COVID-19 pandemic: a systematic review

PURPOSE

Mental health is shaped by social and economic contexts, which were altered during the COVID-19 pandemic. No study has systematically reviewed the literature on the relation between different assets and depression during the COVID-19 pandemic.

METHODS

We conducted a systematic review of the literature on financial (e.g. income/savings), physical (e.g., home ownership), and social (e.g., marital status, educational attainment) assets and depression in U.S. adults. For each asset type, we created binary comparisons to report on the direction of the relationship and described if each study reported insignificant, positive, negative, or mixed associations.

RESULTS

Among the 41 articles identified, we found that income was the most studied asset (n=34), followed by education (n=25), marital status (n=18), home ownership (n=5), and savings (n=4). 88%, 100%, and 100% of articles reported a significant association of higher income, home ownership, and higher savings, respectively, with less depression. The association between marital status and education with depression was more nuanced: 72% (13 of 18) studies showed that unmarried persons had greater risk of depression than married or cohabitating persons and 52% (13 of 25) of studies reported no significant difference in depression across educational groups.

CONCLUSION

This work adds to the literature a deeper understanding of how different assets relate to depression. In the context of largescale traumatic events, policies that maintain and protect access to social, physical, and financial assets may help to protect mental health.

Poverty and birth cohort effects of experiencing the 2007-2009 Great Recession during adolescence on major depressive episodes and mental health treatment of young adults in the United States

PURPOSE

Household economic adversity during adolescence is hypothesized to be a risk factor for poor mental health later in life. To test this hypothesis, we conducted a quasi-experimental analysis of an economic shock, the Great Recession of 2007-2009. We tested if going through adolescence during the Great Recession was associated with increased risk of major depressive episodes (MDE) and mental health treatment in young adulthood with potential moderation by household poverty to explore differences by economic adversity.

METHODS

We analyzed data on young adults age 18-29 years from the 2005-2019 National Survey on Drug Use and Health (N = 145,394). We compared participants who were adolescents during the recession to those followed-up prior to the recession. Regression analysis tested effect modification by household poverty status.

RESULTS

Adolescent exposure to the Great Recession was associated with higher likelihood of MDE during young adulthood (aOR = 1.30, 95% CI = 1.23, 1.37); there was no relationship with mental health treatment. Effects on MDE were stronger among those in households with higher incomes compared to those living in poverty.

CONCLUSION

Findings support the hypothesis that exposure to the Great Recession during adolescence may have increased risk for MDE, but raise questions about whether the mechanism of this association is economic distress.

The missing hallmark of health: psychosocial adaptation

The eight biological hallmarks of health that we initially postulated (Cell. 2021 Jan 7;184(1):33-63) include features of spatial compartmentalization (integrity of barriers, containment of local perturbations), maintenance of homeostasis over time (recycling & turnover, integration of circuitries, rhythmic oscillations) and an array of adequate responses to stress (homeostatic resilience, hormetic regulation, repair & regeneration). These hallmarks affect all eight somatic strata of the human body (molecules, organelles, cells, supracellular units, organs, organ systems, systemic circuitries and meta-organism). Here we postulate that mental and socioeconomic factors must be added to this 8×8 matrix as an additional hallmark of health ("psychosocial adaptation") and as an additional stratum ("psychosocial interactions"), hence building a 9×9 matrix. Potentially, perturbation of each of the somatic hallmarks and strata affects psychosocial factors and vice versa. Finally, we discuss the (patho)physiological bases of these interactions and their implications for mental health improvement.

When money and mental health problems pile up: The reciprocal relationship between income and psychological distress

Background

Longitudinal studies suggest that socioeconomic status (SES) and mental health have a bidirectional relationship such that SES declines lead to a deterioration of mental health (social causation), while worsening mental health leads to SES declines (social drift). However, the dynamic relationship between income and psychological distress has not been sufficiently studied.

Methods

We use cross-lagged panel models with unit fixed effects (FE-CLPM) and data from a five-wave representative panel (n = 3103) of working-age (18-64) New York City adults. Yearly measures include individual earnings, family income (income-to-needs), and psychological distress. We also examine effects by age, gender, education, and racial/ethnic identification.

Results

We find significant bidirectional effects between earnings and distress. Increases in past-year individual earnings decrease past-month psychological distress (social causation effect [SCE], standardized β= -0.07) and increases in psychological distress reduce next-year individual earnings (social drift effect [SDE], β= -0.03). Family income and distress only have a unidirectional relationship from past-year family income to distress (SCE, β= -.03). Strongest evidence of bidirectional effects between earnings and distress is for prime working-age individuals (SCE, β= -0.1; SDE, β= -0.03), those with less than bachelor's degrees (SCE, β= -0.08; SDE, β= -0.05), and Hispanics (SCE, β= -0.06; SDE, β= -0.08). We also find evidence of reciprocal effects between family income and distress for women (SCE, β= -0.03; SDE, β= -0.05), and Hispanics (SDE, β= -0.04; SDE, β= -0.08).

Conclusions

Individual earnings, which are labor market indicators, may be stronger social determinants of mental health than family income. However, important differences in social causation and social drift effects exist across groups by age, education, gender, and racial/ethnic identities. Future research should examine the types of policies that may buffer the mental health impact of negative income shocks and the declines in income associated with worsening mental health, especially among the most vulnerable.

Conceptualising the social in mental health and work capability: implications of medicalised framing in the UK welfare system

PURPOSE

This paper asks whether the separation of mental health from its wider social context during the UK benefits assessment processes is a contributing factor to widely recognised systemic difficulties, including intrinsically damaging effects and relatively ineffective welfare-to-work outcomes.

METHODS

Drawing on multiple sources of evidence, we ask whether placing mental health-specifically a biomedical conceptualisation of mental illness or condition as a discrete agent-at the core of the benefits eligibility assessment process presents obstacles to (i) accurately understanding a claimant's lived experience of distress (ii) meaningfully establishing the specific ways it affects their capacity for work, and (iii) identifying the multifaceted range of barriers (and related support needs) that a person may have in relation to moving into employment.

RESULTS

We suggest that a more holistic assessment of work capacity, a different kind of conversation that considers not only the (fluctuating) effects of psychological distress but also the range of personal, social and economic circumstances that affect a person's capacity to gain and sustain employment, would offer a less distressing and ultimately more productive approach to understanding work capability.

CONCLUSION

Such a shift would reduce the need to focus on a state of medicalised incapacity and open up space in encounters for more a more empowering focus on capacity, capabilities, aspirations, and what types of work are (or might be) possible, given the right kinds of contextualised and personalised support.

Prescription for Cash? Cash Support to Low-Income Families in Maternal and Pediatric Health Care Settings

Policy Points Pregnancy and childhood are periods of heightened economic vulnerability, but current policies for addressing health-related social needs, including screening and referral programs, may be insufficient because of persistent gaps, incomplete follow-up, administrative burden, and limited take-up. To bridge gaps in the social safety net, direct provision of cash transfers to low-income families experiencing health challenges during pregnancy, infancy, and early childhood could provide families with the flexibility and support to enable caregiving, increase access to health care, and improve health outcomes.

The fallacy of global comparisons based on per capita measures

Media, social scientists and public health researchers often present comparisons across countries, and policy makers use such comparisons to take evidence-based action. For a meaningful comparison among countries, one often needs to normalize the measure for differences in population size. To address this issue, the first choice is usually to calculate per capita ratios. Such ratios, however, normalize the measure for differences in population size directly only under the highly restrictive assumption of a proportional increase of the measure with population size. Violation of this assumption frequently leads to misleading conclusions. We compare per capita ratios with an approach based on regression, a widely used statistical procedure that eliminates many of the problems with ratios and allows for straightforward data interpretation. It turns out that the per capita measures in three global datasets (gross domestic product, COVID-19-related mortality and CO2 production) systematically overestimate values in countries with small populations, while countries with large populations tend to have misleadingly low per capita ratios owing to the large denominators. Unfortunately, despite their biases, comparisons based on per capita ratios are still ubiquitous, and they are used for influential recommendations by various global institutions. Their continued use can cause significant damage when employed as evidence for policy actions and should therefore be replaced by a more scientifically substantiated and informative method, such as a regression-based approach.

Association between the perceived value of adopting new behaviors and depressive symptoms among older adults

Early preventive measures against depression have become important with unprecedented global aging. Increase in one's perceived value (PV) may correspond to better mental health outcomes. This cross-sectional observation study aimed to clarify whether the PV of adopting new behaviors is associated with depressive symptoms. The participants were 5266 community-dwelling older adults aged ≥ 65 years. We developed a questionnaire to measure the PV of adopting new behaviors, specifically activities beneficial for preventing depressive symptoms (physical, cognitive, and social activities) in older adults. The questionnaire asked whether adopting the ten selected behaviors was valuable. The scores were added, and the total score ranged from - 20 to 20. The odds ratios (OR) of depressive symptoms were calculated using binomial logistic regression according to the PV score quartiles. Depressive symptoms were reported by 595 (11.3%) participants. After adjusting for potential confounders, higher quartiles of PV scores were significantly associated with lower prevalence of depressive symptoms: vs Q1; Q2 OR 0.76 (95% confidence interval: 0.59-0.97); Q3 0.67 (0.51-0.87); Q4 0.54 (0.40-0.73) (P for trend < .001). Having a higher PV of adopting new behaviors may prevent depressive symptoms among older adults. Healthcare professionals need to pay attention to poor value orientation among older adults.

Characterizing Aging-Related Health in Older Women with a History of Incarceration: Multimorbidity, Polypharmacy, Mortality, Frailty, and Depression

OBJECTIVE

To characterize aging-related health in women with past CLSI and compare with women with no-CLSI.

METHOD

Health and Retirement Study Wave 11 and 12 data from women age >50 with CLSI were compared with data from women age >50 with no-CLSI. Generalized linear models were estimated for aging-related health outcomes.

RESULTS

The group with CLSI (n = 230) was significantly younger than the no-CLSI group (n = 8035) yet had more physical, functional, and mental health challenges and fewer resources. Incarceration significantly predicted aging-related outcomes of multimorbidity, polypharmacy, mortality, frailty, and depression.

DISCUSSION

Earlier onset of physical and functional health conditions in women with past CLSI has implications for health education and promotion, clinical practice, and intervention design.

Life Satisfaction Factors, Stress, and Depressive Symptoms among Young Women Living in Urban Kampala: Findings from the TOPOWA Project Pilot Studies

Young women living in Kampala, Uganda, often face adversities related to Social Determinants of Mental Health (SDoMH) including poverty, food scarcity, environmental stressors such as high levels of community violence, and lack of adequate healthcare access. Two consecutive pilot studies were conducted to assess the feasibility and acceptability of survey questions, wearable fitness trackers, and daily diaries before launching a larger prospective cohort study. Preliminary associations between SDoMH factors with depressive symptoms, stress levels, and life satisfaction were examined among the total sample of 60 women across two pilot studies. A total of 32.2% of respondents (out of n = 59) reported being depressed most or all of the time in the past 30 days. Frequent depressive symptoms correlated with food insecurity (χ2 = 5.38, df = 1, p = 0.02). Higher stress levels were significantly associated with lower overall life satisfaction scores (t = 2.74, df = 6.20, p = 0.03). Additionally, frequent depressive symptoms were associated with lower satisfaction scores in the living conditions and lifestyle domain (t = 2.22, df = 36.18, p = 0.03). However, overall life satisfaction scores and other domains (social relationships and personal independence) were not statistically associated with frequent depressive symptoms. Identifying the most impactful SDoMH factors among young women in Kampala can inform targeted approaches to improve mental health outcomes.

Expanding the notion of mechanism to further understanding of biopsychosocial disorders? Depression and medically-unexplained pain as cases in point

Evidence-Based Medicine has little consideration for mechanisms and philosophers of science and medicine have recently made pleas to increase the place of mechanisms in the medical evidence hierarchy. However, in this debate the notions of mechanisms seem to be limited to 'mechanistic processes' and 'complex-systems mechanisms,' understood as 'componential causal systems'. I believe that this will not do full justice to how mechanisms are used in biological, psychological and social sciences and, consequently, in a more biopsychosocial approach to medicine. Here, I propose, following (Kuorikoski, 2009), to pay more attention to 'abstract forms of interaction' mechanisms. The present work scrutinized review articles on depression and medically unexplained pain, which are considered to be of multifactorial pathogenesis, for their use of mechanisms. In review articles on these disorders there seemed to be a range of uses between more 'abstract forms of interaction' and 'componential causal system' mechanisms. I therefore propose to expand the notions of mechanisms considered in medicine to include that of more 'abstract forms of interaction' to better explain and manage biopsychosocial disorders.
