The relationship between sexual and gender stigma and suicide attempt and ideation among LGBTQI + populations in Thailand: findings from a national survey

Purpose

Thailand has one of the highest suicide rates in Southeast Asia; yet, little is known about suicidality among lesbian, gay, bisexual, trans, queer, intersex, and other gender and sexually diverse (LGBTQI +) people living in the region, who may experience elevated risk for suicide. We sought to identify the prevalence of lifetime suicidal attempts and ideation among a nationally recruited sample of LGBTQI + people in Thailand. We further examined the relationship between levels of sexual/gender stigma and suicidal attempt and ideation.

Methods

Data were derived from a national online survey of Thai LGBTQI + individuals between January and March 2018. Multivariable logistic regression was used to examine the relationship between sexual/gender stigma scales, adapting a previously validated instrument, and suicide attempt and ideation.

Results

Among 1,290 LGBTQI + participants, the median age was 27 years. The prevalence of suicide attempt and ideation was 16.8% and 50.7%, respectively. In multivariable analyses, after adjusting for potential confounders, experiences of perceived and enacted sexual/gender stigma were independently and positively associated with suicide attempt (adjusted odds ratio [AOR] = 1.25; 95% confidence interval CI:1.10–1.41 and AOR = 1.31; 95% CI:1.11–1.55, respectively) and ideation (AOR = 1.30; 95% CI:1.17–1.43 and AOR = 1.34; 95% CI:1.14–1.58, respectively).

Conclusion

One-sixth of the sample reported a suicide attempt, while a half reported ever contemplating suicide. Both experiences of perceived and enacted sexual/gender stigma were associated with lifetime suicide attempt and ideation. Multi-level interventions are needed to decrease stigma and in turn suicide among LGBTQ + people in Thailand, including anti-discrimination policies and support for mental health and well-being.

     

Self-reported auditory problems are associated with adverse mental health outcomes and alcohol misuse in the UK Armed Forces

Purpose

Auditory problems, such as hearing loss and tinnitus, have been associated with mental health problems and alcohol misuse in the UK general population and in the US Armed Forces; however, few studies have examined these associations within the UK Armed Forces. The present study examined the association between auditory problems and probable common mental disorders, post-traumatic stress disorder and alcohol misuse.

Methods

5474 serving and ex-service personnel from the UK Armed Forces were examined, selected from those who responded to phase two (data collection 2007–09) and phase three (2014–16) of a military cohort study. Multivariable logistic regression was used to examine the association between auditory problems at phase two and mental health problems at phase three.

Results

9.7% of participants reported ever experiencing hearing problems alone, 7.9% reported tinnitus within the last month alone, and 7.8% reported hearing problems with tinnitus. After adjustment, hearing problems with tinnitus at phase two was associated with increased odds of probable common mental disorders (AOR = 1.50, 95% CI 1.09–2.08), post-traumatic stress disorder (AOR = 2.30, 95% CI 1.41–3.76), and alcohol misuse (AOR = 1.94, 95% CI 1.28–2.96) at phase three. Tinnitus alone was associated with probable post-traumatic stress disorder (AOR = 1.80, 95% CI 1.03–3.15); however, hearing problems alone were not associated with any outcomes of interest.

Conclusions

The association between auditory problems and mental health problems emphasises the importance of the prevention of auditory problems in the Armed Forces: through enhanced audiometric screening, improved hearing protection equipment, and greater levels of utilisation of such equipment.

     

The effect of gender on the long-term course and outcome of schizophrenia in rural Ethiopia: a population-based cohort

Background

Although some studies have suggested that women with schizophrenia are more likely to achieve positive outcomes, the evidence-base is fraught with inconsistencies. In this study we compare the long-term course and outcomes for men and women living with schizophrenia in rural Ethiopia.

Methods

The Butajira course and outcome study for severe mental disorders is a population-based cohort study. Community ascertainment of cases was undertaken between 1998 and 2001, with diagnostic confirmation by clinicians using the Schedules for Clinical Assessment in Neuropsychiatry. Findings from annual outcome assessments were combined with clinical records, patient and caregiver report, and psychiatric assessments at 10–13 years using the Longitudinal Interval Follow-up Evaluation- LIFE chart. For the sub-group of people with schizophrenia (n = 358), we compared course of illness and treatment, co-morbidity, recovery, social outcomes and mortality between men and women. Multivariable analyses were conducted for modelling associations identified in bivariate analyses according to blocks shaped by our a priori conceptual framework of the biological and social pathways through which gender might influence the course and outcome of schizophrenia.

Results

Looking into over 10–13 years of follow-up data, there was no difference in the functioning or recovery in women compared to men (AOR = 1.79, 95% CI = 0.91, 3.57). Women were less likely to report overall life satisfaction (AOR = 0.22, 95% CI = 0.09, 0.53) or good quality of spousal relationships (AOR = 0.09, 95% CI = 0.01–1.04). Men were more likely to have co-morbid substance use and there was a trend towards women being more likely to be prescribed an antidepressant (AOR = 2.38, 95% CI = 0.94, 5.88). There were no gender differences in the course of illness, number of psychotic episodes or adherence to medications.

Conclusion

In this rural African setting, we found little evidence to support the global evidence indicating better course and outcome of schizophrenia in women. Our findings are suggestive of a gendered experience of schizophrenia which varies across contexts. Further investigation is needed due to the important implications for the development of new mental health services in low and middle-income country settings.

     

Association between body weight status and suicidal ideation among Chinese adolescents: the moderating role of the child’s sex

Purpose

Suicidality (ranging from suicidal ideation to suicidal attempts and completed suicide) is a major and preventable public health concern, and body weight is considered a modifiable factor which might be helpful to the early risk assessment of suicidal ideation. This study aimed to comprehensively evaluate the association of body weight status with suicidal ideation across sex among Chinese adolescents.

Methods

Data were drawn from the 2015 National School-based Chinese Adolescents Health Survey, and 54,640 students’ questionnaires were completed and qualified for the survey. Body mass index z scores were calculated and categorized into four levels: underweight (less than the 5th percentile for sex and age), normal weight (between the 5th and 85th percentile), overweight (between the 85th and 95th percentile), and obese (above the 95th percentile).

Results

Of the total sample, 47.3% (25,852) were boys. The weighted prevalence of suicidal ideation among Chinese adolescents is 15.7% (14.6% in boys and 17.3% in girls). After adjusting for demographics, smoking, drinking, and depressive symptoms, our final multivariate logistic regression models demonstrated that only boys identified as underweight (Adjusted odds ratio [AOR] = 1.23, 95% CI = 1.06–1.44) or obese (AOR = 1.19, 95% CI = 1.02–1.38) were at a higher risk of suicidal ideation. Additionally, the association between weight status and suicidal ideation among boys might be moderated by academic pressure, smoking, and depressive symptoms.

Conclusions

There was a significant J-shaped association between relative body weight and suicidal ideation in boys. The child’s sex should be taken into consideration when developing interventions against unhealthy weight and suicidal ideation.

     

Food insecurity and its associations with bulimic-spectrum eating disorders,mood disorders,and anxiety disorders in a nationally representative sample of U.S. adults

Purpose

To examine cross-sectional associations between food insecurity and 12-month eating disorders, mood disorders, and anxiety disorders among U.S. adults.

Methods

This study used data collected between 2001 and 2003 from 2914 participants in the National Comorbidity Survey-Replication, a nationally representative sample of U.S. adults (mean age = 44.9 years; 53.4% female). Twelve-month food insecurity was assessed with a modified version of the Short Form U.S. Household Food Security Scale. Twelve-month DSM-IV diagnoses of mental disorders were based on the World Health Organization Composite International Diagnostic Interview. Modified Poisson regression models were conducted, adjusting for age, sex, race/ethnicity, education, and income-to-poverty ratio.

Results

Food insecurity was experienced by 11.1% of participants. Food insecurity was associated with greater prevalence of bulimic-spectrum eating disorders (prevalence ratio [PR] = 3.81; 95% confidence interval [CI] 2.26–6.42), mood disorders (PR = 2.53; 95% CI 1.96–3.29), and anxiety disorders (PR = 1.69; 95% CI 1.39–2.07).

Conclusion

Results indicate that food insecurity is associated with a range of internalizing mental disorders, though these findings should be confirmed with contemporary data to reflect DSM-5 diagnostic updates and the economic effects of the COVID-19 pandemic. Findings from this study emphasize the need to expand food insecurity interventions and improve access to mental health services for food-insecure populations.

     

Neighbourhood characteristics and social isolation of people with psychosis: a multi-site cross-sectional study

Purpose

People with psychosis are vulnerable to social isolation, which is associated with worse clinical outcomes. In general populations, people living in areas with higher population density have more social contacts, while those living in more socially deprived and fragmented areas are less satisfied with their relationships. We assessed whether and how neighbourhood factors are associated with social contacts and satisfaction with friendships for people with psychosis.

Methods

We carried out a cross-sectional study including people with psychosis aged 18–65 years in urban and rural sites in England. Population density and social deprivation and fragmentation indexes were described within Lower Level Super Output Areas (LSOA). Their associations with participants’ social contacts and satisfaction with friendships were tested with negative binomial and ordinal regression models, respectively.

Results

We surveyed 511 participants with psychotic disorders. They had a median of two social contacts in the previous week (interquartile range [IQR] = 1–4), and rated satisfaction with friendships as 5 out of 7 (Manchester Short Assessment of Quality of Life; IQR = 4–6). Higher population density was associated with fewer social contacts (Z-standardised relative risk [RR] = 0.88; 95% CI = 0.79–0.99, p = 0.03), but not with satisfaction with friendships (RR = 1.08; 95% CI = 0.93–1.26, p = 0.31). No associations were found for social contacts or satisfaction with friendships with social deprivation or fragmentation indexes.

Conclusions

Clinicians in urban areas should be aware that their patients with psychosis are more socially isolated when more people live around them, and this could impact their clinical outcomes. These findings may inform housing programmes.

     

The nexus between urban green space,housing type,and mental health

Introduction

Momentum for urban densification is increasing opportunities for apartment-living, but can result in reduced green space availability that negatively influences mental health. However, in contexts where apartment-living is atypical and commonly viewed as secondary to house-ownership, it may be a stressful antecedent condition (or marker of selective processes aligned with psychological distress) wherein occupants could benefit disproportionately from green space.

Method

Data were extracted from the Sax Institute’s 45 and Up Study baseline (2006–2009, n = 267,153). The focus was on subsets of 13,196 people living in apartments and 66,453 people living in households within the cities of Sydney, Newcastle and Wollongong. Multilevel models adjusted for confounders tested associations between psychological distress (Kessler 10 scale) with percentage total green space, tree canopy and open grass within 1.6 km road network buffers.

Results

Psychological distress was higher in occupants of apartments (11.3%) compared with houses (7.9%). More green space was associated with less psychological distress for house-dwellers (OR = 0.94, 95% CI = 0.91–0.98), but there was no association for apartment-dwellers. More tree canopy was associated with lower psychological distress for house-dwellers (OR = 0.88, 95% CI = 0.85–0.92) and apartment-dwellers (OR = 0.87, 95% CI = 0.79–0.96). Open grass was associated with more psychological distress among house-dwellers (OR = 1.06, 95% CI = 1.00–1.13) and also for apartment-dwellers (OR = 1.20, 95% CI = 1.07–1.35).

Conclusions

Overall, investments in tree canopy may benefit the mental health of house and apartment residents relatively equally. Urban tree canopy in densely populated areas where apartments are common needs to be protected. Further work is needed to understand factors constraining the prevention potential of open grass, to unlock its benefits for mental health.

     

Prevalence and clinical correlates of substance use disorders in South African Xhosa patients with schizophrenia

Purpose

To determine the prevalence of substance use disorders (SUDs) in patients with schizophrenia in a sample from South Africa and compare the clinical and demographic correlates in those with and without co-occurring SUDs.

Methods

Patients with schizophrenia were interviewed using the Xhosa version SCID-I for DSM-IV. We used logistic regression to determine the predictors of SUDs.

Results

In the total sample of 1420 participants, SUDs occurred in 47.8%, with the most prevalent SUD being cannabis use disorders (39.6%), followed by alcohol (20.5%), methaqualone (6.2%), methamphetamine (4.8%) and other SUDs (cocaine, ecstasy, opioids, 0.6%). Polydrug use occurred in 40%, abuse occurred in 13.5%, and 39.6% had at least one substance dependence diagnosis. Significant predictors of any SUD were younger age (41–55 vs. 21–30: OR = 0.7, 95% CI = 0.5–0.9), male sex (OR = 8.6, 95% CI = 5.1–14.6), inpatient status (OR = 1.7, 95% CI = 1.3–2.1), post-traumatic stress symptoms (OR = 4.6, 95% CI = 1.6–13.3), legal (OR = 3.4, 95% CI = 2.0–5.5) and economic problems (OR = 1.4, 95% CI = 1.0–2.0). Methamphetamine use disorders occurred significantly less often in the Eastern compared to the Western Cape provinces. Inpatient status and higher levels of prior admissions were significantly associated with cannabis and methamphetamine use disorders. Post-traumatic stress symptoms were significantly associated with alcohol use disorders. Anxiety disorders were associated with other SUDs.

Conclusion

SUDs occurred in almost half of the sample. It is important for clinicians to identify the presence of SUDs as their presence is associated with characteristics, such as male sex, younger age, inpatient status, more prior hospitalisations, legal and economic problems, PTSD symptoms and anxiety.

     

Health,social and criminal justice factors associated with dual diagnosis among incarcerated adults in Brazil and Australia: a cross-national comparison

Purpose

To estimate the prevalence of dual diagnosis and identify health, social and criminal justice factors associated with dual diagnosis among incarcerated adults in Australia and Brazil.

Methods

We compared data from cross-sectional surveys of incarcerated adults (aged ≥ 18 years) in Australia and Brazil. Using data from linked emergency department, hospital, and in-prison medical records in the Australian sample, and from the Composite International Diagnostic Interview (CIDI) in the Brazilian sample, participants were categorised as having: (1) no mental disorder; (2) substance use disorder only; (3) mental illness only; or (4) dual diagnosis. A multivariate multinomial logistic regression model was fitted to identify factors associated with dual diagnosis in each country.

Results

Approximately one quarter of participants in both Australia (22%) and Brazil (25%) met the diagnostic criteria for dual diagnosis. In both countries, dual diagnosis was associated with being female [relative risk (RR) = 2.25 (95% CI 1.47–3.43) Australia; RR = 2.59 (95% CI 1.79–3.74) Brazil], having a history of prior incarceration [RR = 2.99 (95% CI 1.99–4.48) Australia; RR = 2.27 (95% CI 1.57–3.29) Brazil], and having comorbid physical health problems [RR = 1.54 (95% CI 1.08–2.19) Australia; RR = 2.53 (95% CI 1.75–3.65) Brazil].

Conclusions

Despite differences in health, social, and criminal justice systems between Australia and Brazil, the prevalence of and factors associated with dual diagnosis in incarcerated adults appear to be similar in the two countries. A number of generalisable principles can be inferred and should be considered in health and criminal justice policy making.

     

Exploring depressive symptoms and its associates among Bangladeshi older adults amid COVID-19 pandemic: findings from a cross-sectional study

Purpose

Depression, one of the most common mental disorders, is up-surging worldwide amid the ongoing coronavirus disease 2019 (COVID-19) pandemic, especially among the older population. This study aims to measure prevalent depressive symptoms and its associates among older adults amid the COVID-19 pandemic in Bangladesh.

Methods

This cross-sectional study was carried out among 1032 older Bangladeshi adults, aged 60 years and above, through telephone interviews in October 2020. We used a semi-structured questionnaire to collect data on participants’ socio-demographic and lifestyle characteristics, pre-existing medical conditions, and COVID-19-related information. Meanwhile, depressive symptoms were measured using the 15-item Geriatric Depression Scale (GDS-15). The binary logistic regression model was used to identify the factors associated with depressive symptoms.

Results

Two-in-five participants showed depressive symptoms on the GDS-15 scale. Poor socioeconomic characteristic such as low family income, dependency on the family for living, recipient of financial support during the pandemic was associated with higher odds of depressive symptoms. Participants with pre-existing medical conditions had 91% higher odds of depressive symptoms. Social isolation, captured in terms of living alone (aOR = 2.11, 95% CI 1.11–4.01), less frequent communication during pandemic (aOR = 1.55, 95% CI 1.07–2.26), perceived loneliness (aOR = 2.25, 95% CI 1.47–3.45), and isolation from others (aOR = 2.45, 95% CI 1.62–3.70) were associated with higher odds of depressive symptoms.

Conclusions

Our study found a sizeable proportion of study participants with depressive symptoms amidst the ongoing pandemic. The findings of the present study call for the urgent need for mental health support package targeting this vulnerable group of population.

     

Mental health of clinical staff working in high-risk epidemic and pandemic health emergencies a rapid review of the evidence and living meta-analysis

Purpose

The SARS-CoV-2 / COVID-19 pandemic has raised concerns about the potential mental health impact on frontline clinical staff. However, given that poor mental health is common in acute medical staff, we aimed to estimate the additional burden of work involving high exposure to infected patients.

Methods

We report a rapid review, meta-analysis, and living meta-analysis of studies using validated measures from outbreaks of COVID-19, Ebola, H1N1 influenza, Middle East respiratory syndrome (MERS), and severe acute respiratory syndrome (SARS).

Results

A random effects meta-analysis found that high-exposure work is not associated with an increased prevalence of above cut-off scoring (anxiety: RR = 1.30, 95% CI 0.87–1.93, Total N = 12,473; PTSD symptoms: RR = 1.16, 95% CI 0.75–1.78, Total N = 6604; depression: RR = 1.50, 95% CI 0.57–3.95, Total N = 12,224). For continuous scoring, high-exposure work was associated with only a small additional burden of acute mental health problems compared to low-exposure work (anxiety: SMD = 0.16, 95% CI 0.02–0.31, Total N = 6493; PTSD symptoms: SMD = 0.20, 95% CI 0.01–0.40, Total N = 5122; depression: SMD = 0.13, 95% CI -0.04–0.31, Total N = 4022). There was no evidence of publication bias.

Conclusion

Although epidemic and pandemic response work may add only a small additional burden, improving mental health through service management and provision of mental health services should be a priority given that baseline rates of poor mental health are already very high. As new studies emerge, they are being added to a living meta-analysis where all analysis code and data have been made freely available: https://osf.io/zs7ne/.

     

Risk factors for anxiety of otolaryngology healthcare workers in Hubei province fighting coronavirus disease 2019 (COVID-19)

Purpose

To ensure the mental health of the otolaryngology healthcare workers in the fight against coronavirus disease 2019 (COVID-19), it is important to know their mental status and to identify possible risk factors. In this study, we investigated the risk factors for the anxiety in the otolaryngology healthcare workers in Hubei province under the COVID-19 epidemic.

Methods

The otolaryngology healthcare workers in Hubei Province were surveyed using an online questionnaire in which anxiety was measured against the Zung Self-rating Anxiety Scale. Univariate and multivariate logistic regression analyses were used to evaluate the risk factors of anxiety.

Results

A total of 449 otolaryngology healthcare workers participated in the study. Of all the participants, 131 (29.18%) had anxiety symptoms. Compared with doctors, nurses were at a higher risk for anxiety (OR = 2.162, 95% CI 1.311–3.566). Participants who often suspected self-infection (OR = 4.239, 95% CI 1.647–10.909) or family member infection by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (OR = 4.485, 95% CI 1.511–13.313) were more likely to develop anxiety than those who never. The subjects who had colleagues diagnosed with COVID-19 were more vulnerable to anxiety (OR = 2.014, 95% CI 1.205–3.366). Respondents working in infectious isolation wards had a 3.522-fold increased risk of anxiety compared to those on leave (OR = 3.522, 95% CI 1.634–7.593).

Conclusion

Some otolaryngology healthcare workers in Hubei province experienced anxiety during the epidemic, but most of them did not receive treatment. The healthcare providers themselves should be informed about and aware of their own mental health, and should be given support as appropriate.

Compulsory admission at first presentation to services for psychosis: does ethnicity still matter? Findings from two population-based studies of first episode psychosis

Objectives

Compared with the majority population, those from minority ethnic groups in the UK are more likely to be admitted compulsorily during a first episode of psychosis (FEP). We investigated whether these disparities in pathways in to care continue.

Methods

We analysed data from two first episode psychosis studies, conducted in the same geographical area in south London 15 years apart: the Aetiology and Ethnicity in Schizophrenia and Other Psychosis (AESOP) and the Clinical Record Interactive Search-First Episode Psychosis (CRIS-FEP) studies. The inclusion/exclusion criteria for case ascertainment for first episode psychosis were identical across the two studies. We performed multivariable logistic regression to estimate odds of compulsory admission by ethnic group, controlling for confounders.

Participants

Two hundred sixty-six patients with first episode psychosis, aged 18–64 years, who presented to mental health services in south London in 1997–1999 and 446 with FEP who presented in 2010–2012.

Results

When the two samples  were compared, ethnic differences in compulsory admission appear to have remained the same for black African patients, i.e. three times higher than white British in both samples: AESOP (adj. OR = 3.96; 95% CI = 1.80–8.71) vs. CRIS-FEP (adj. OR = 3.12; 95% CI = 1.52–6.35). Black Caribbean patients were three times more likely to be compulsorily admitted in AESOP (adj. OR = 3.20; 95% CI = 1.56–6.54). This was lower in the CRIS-FEP sample (adj. OR = 1.68; 95% CI = 0.71–3.98) and did not meet conventional levels for statistical significance.

Conclusion

Ethnicity is strongly associated with compulsory admissions at first presentation for psychosis with evidence of heterogeneity across groups, which deserves further research.

     

Association between history of miscarriage and autism spectrum disorder

This case–control study was designed to examine the association between different types of miscarriage history and autism spectrum disorder (ASD), and determine whether the number of miscarriage history affects the risk of ASD. All of 2274 children with ASD and 1086 healthy controls were recruited. Sociodemographic and prenatal, perinatal, and neonatal characteristics were compared between the two groups. Multivariable logistic regression analyses were applied to investigate association between miscarriage history and ASD. Stratified analyses based on sex and types of miscarriages were similarly performed. History of miscarriage was potential risk factors for ASD ([aOR] = 2.919; 95% [CI] = 2.327–3.517). Stratified analyses revealed that induced ([aOR] = 2.763, 95% [CI] = 2.259–3.379) and spontaneous miscarriage history ([aOR] = 3.341, 95% [CI] = 1.939–4.820) were associated with high risk of ASD, respectively. A sex-biased ratio in the risk of ASD was observed between females ([aOR] = 3.049, 95% [CI] = 2.153–4.137) and males ([aOR] = 2.538, 95% [CI] = 1.978–3.251). Stratified analysis of induced miscarriage history revealed that only iatrogenic miscarriage history was associated with an increased risk ASD ([aOR] = 2.843, 95% [CI] = 1.534–4.268). Also, multiple spontaneous miscarriage histories ([aOR] = 1.836, 95% [CI] = 1.252–2.693) were associated with higher autism risk than one spontaneous miscarriages history ([aOR] = 3.016, 95% [CI] = 1.894–4.174). In conclusion, miscarriage history is related to an increased risk for ASD in offspring, which is affected by the types of miscarriage and sex of the fetus.

     

The impact of transitions from employment to retirement on suicidal behaviour among older aged Australians

Purpose

Transition from employment to retirement may be detrimental to mental health, and associated with suicidal behaviour. This study investigated the association between employment and retirement status and suicidal behaviour among older aged Australians.

Methods

This study was based on the ‘45 and Up Study’, a large prospective cohort study of participants from New South Wales (Australia) aged 45 years and older (N = 267,153), followed up over the period 2006–2018. The risk of attempted suicide and suicide was compared between categories of employment and retirement status in a series of recurrent event survival analysis models adjusting for identified time variant and invariant confounders.

Results

Compared to those who were employed, the risk of attempted suicide was higher among those who were not in the labour force and not retired (predominantly those who were sick or disabled, or carers) (HR = 1.97–95% CI 1.49–2.62), those who retired involuntarily (HR = 1.35–95% CI 1.03–1.77), and to a lesser extent those unemployed (HR = 1.31–95% CI 0.89–1.92). Risk of attempted suicide among those who retired voluntarily was similar to those who remained employed (HR = 1.09–95% CI 0.82–1.45). A similar pattern was evident for suicide, with a higher risk of suicide among those who were not in the labour force or retired, and those who retired involuntarily, compared to those who remained employed; however, these differences were not statistically significant.

Conclusion

Transition from employment to retirement may be an important precipitating factor for suicidal behaviour, affected by current and previous mental health status. Services and programs facilitating continued or re-employment in older age, and adjustment to the transition from employment to retirement may prevent suicidal behaviour.

     

Associations between diet quality and DSM-IV mood disorders during young- to mid-adulthood among an Australian cohort

Purpose

Many studies have reported associations between diet and depression, but few have used formal diagnoses of mood disorder as the outcome measure. We examined if overall diet quality was associated cross-sectionally or longitudinally with DSM-IV mood disorders among an adult cohort.

Methods

Participants from the Australian Childhood Determinants of Adult Health study were followed up during 2004–06 (n = 1974, age 26–36 years), 2009–11 (n = 1480, 31–41 years), and 2014–19 (n = 1191, 36–49 years). Dietary Guidelines Index (DGI) scores were calculated from food frequency questionnaires at each time-point (higher DGI reflects better diet quality). DSM-IV mood disorders (dysthymia or depression) during the periods between, and 12 months prior to each follow-up were determined using the Composite International Diagnostic Interview. Sex-stratified risk and prevalence ratios (PR) and 95% confidence intervals (CI) were estimated using log-binomial regression. Covariates included age, self-perceived social support index score, marital status, parenting status, education, occupation, physical activity, BMI, and usual sleep duration.

Results

A 10-point higher DGI was cross-sectionally associated with lower prevalence of mood disorders at the third follow-up only (females PR = 0.73, 95% CI = 0.56, 0.95; males PR = 0.72, 95% CI = 0.53, 0.97), but was attenuated after covariate adjustment (females PR = 0.92, 95% CI = 0.73, 1.16; males PR = 0.92, 95% CI = 0.69, 1.22). Adjustment for social support in the final model had attenuated the association for both sexes from 18% reduced prevalence to 8%. DGI scores were not longitudinally associated with mood disorder risk.

Conclusions

Crude cross-sectional associations between diet quality and mood disorders at ages 36–49 years were explained by sociodemographic and lifestyle factors, particularly social support.

     

Dynamic residential movement and depression among the World Trade Center Health Registry enrollees

Purpose

Residential instability is associated with poor mental health, but its causal inference is challenging due to time-varying exposure and confounding, and the role of changing social environments. We tested the association between frequent residential moving and depression risk among adults exposed to the 9/11 disaster.

Methods

We used four waves of survey data from the World Trade Center Health Registry. We measured residential movement and depression using geocoded annual address records and the Personal Health Questionnaire Depression Scale, respectively, for a prospective cohort of 38,495 adults. We used the longitudinal Targeted Maximum Likelihood Method to estimate depression risk by frequent residential moving and conducted causal mediation analysis to evaluate a mediating role of social environments.

Results

Most enrollees (68%) did not move in 2007–2014, and 6% moved at least once every 4 years. The remaining 26% moved less frequently (e.g., only moving in 2007–2010). Frequent moving versus no moving was associated with risk of depression in 2015–16 (RR = 1.20, 95% CI = 1.06, 1.37). Frequent residential moving—depression pathway was mediated by high social integration (OR = 0.93, 95% CI = 0.90, 0.97).

Conclusion

These findings demonstrate the importance of social networks in understanding increased risk of depression associated with housing instability.

     

Depression risk and body mass index among immigrants and non-immigrants in Canada: results from the Canadian Community Health Surveys, 2010–2014

Purpose

Obesity has been associated with an increased risk of the depression in the general population, but it is unknown whether this relationship applies equally to immigrants as well as non-immigrants. Furthermore, the nature of the relationship is uncertain, is it direct or curvilinear? The aim of this study is to examine the relationship between body mass index and major depressive episode among immigrants and non-immigrants.

Methods

To provide more statistically robust data, a series of cross-sectional health surveys of the Canadian population for the 5 years 2010–2014 were pooled to increase the number of immigrants in the study. Restricted cubic splines analysis was used to examine the nature of the association.

Results

Immigrants had lower 12-month depression and obesity prevalence rates than non-immigrants. In addition, it was found that non-immigrants were more likely to develop depression than immigrants, OR = 1.40 (95% CI, 1.16–1.67). Obese respondents were more likely to develop depression than normal weight respondents in both immigrant (OR = 1.55; 95% CI, 1.03–2.32) and non-immigrant groups (OR = 1.23; 95% CI, 1.15–1.32). A significant nonlinear elongated J-shaped association between obesity and depression was found for both immigrants and non-immigrants with increased risk of depression in obese individuals.

Conclusion

Culture-specific, clinical-based interventions should be developed to improve the early identification, treatment and recovery of individuals with a high BMI particularly among those with BMIs in the obese range.

     

Early age of onset of mood,anxiety and alcohol use disorders is associated with sociodemographic characteristics and health outcomes in adults: results from a cross-sectional national survey

Purpose

This cross-sectional study investigated distribution, sociodemographic correlates, and health outcomes in early versus late age of onset (AOO) of mood, anxiety, and alcohol use disorders in Singapore.

Methods

The Composite International Diagnostic Interview established lifetime diagnoses of major depressive, bipolar, generalized anxiety, obsessive compulsive and alcohol use disorders in a representative sample of residents aged 18 years and over (n = 6126). The AOO of the individual and any mental disorders were classified into early and late onset using median values as cut-offs. Data included socio-demographic and health background, health utility score, and productivity losses. Multivariable logistic regression analysis was conducted to assess sociodemographic correlates of early versus late AOO of any mental disorder while linear regression analysis investigated the associations between AOO of individual disorders with health utility score and productivity loss.

Results

Respondents’ mean (SD) age was 45.6 (16.5) years, comprising 50.5% women and majority of Chinese ethnicity (75.8%). The median AOO for any of the five studied disorders was 21 years (IQR: 15–29). Lowest AOO was observed for obsessive compulsive disorder (Median: 14, IQR: 11–26). Those aged 35 years and over (versus 18–34) were less likely to have earlier AOO [35–49 years (OR: 0.287; 95% CI: 0.154–0.534); 50–64 years (OR:0.156; 95% CI: 0.068–0.361) and 65 and over (OR:0.112; 95% CI:0.027–0.461)], while Malay ethnicity (versus Chinese) (OR: 2.319; 95% CI: 1.384–3.885) and being never married (versus married) (OR: 2.731; 95% CI: 1.493–4.993) were more likely to have early AOO for any mental disorder. Sample with early (versus late) AOO had a lower health utility score (β =  − 0.06,95% CI: − 0.08 to − 0.03) and higher number of days cut down on the type of work (β = 1.61,95% CI: 0.12–3.10) in those with any mental disorders.

Conclusion

This study showed that half of the adults with mood, anxiety or alcohol use disorders in Singapore experienced their illness onset by 21 years of age. Early AOO is associated with sociodemographic background and poor health outcomes. Prevention, early detection, and interventions to improve health outcomes in mental disorders should consider the sociodemographic profile and age at first onset of symptoms in the population.

     

Time trends and disparities in anxiety among adolescents, 2012–2018

Purpose

Prior studies have been inconclusive in documenting whether the prevalence of adolescent anxiety is increasing, given sampling and measurement limitations. This study adds new information on recent time trends in anxiety prevalence, specifically investigating trends among previously unexamined sociodemographic subgroups.

Methods

Weighted data of 37,360 youth respondents (51.1% female, 71.8% White, 91.3% heterosexual, 99.2% cisgender) from the 2012–2018 Dane County Youth Assessment, a county-wide survey administered to youth in participating school districts, were analyzed to estimate time trends in anxiety prevalence among the whole sample and by sociodemographic subgroups.

Results

The prevalence of youth meeting anxiety-screening criteria increased from 34.1% (95% CI 33.4–34.9) in 2012 to 44% (95% CI 43.2–44.7) in 2018 (OR for trend = 1.07, P for trend < 0.001). The trend remained significant after adjusting for known confounds (AOR for trend = 1.07, P for trend < 0.001). Anxiety increased significantly for several subgroups and widening disparities were documented among females relative to males (P < 0.001), and sexual minority youth relative to heterosexual youth (P = 0.003). In addition, Black youth did not increase at the same swift rate as White youth over the study period (P < 0.001).

Conclusion

This study reports recent data on anxiety time trends and finds that among a geographically representative sample of adolescents, anxiety prevalence is rising. Findings provide new evidence documenting increased anxiety prevalence among sexual minority youth relative to their peers. Results highlight the need to bolster public health interventions focused on adolescent mental health, with tailored interventions for vulnerable groups.
