Adolescent depression and adult labor market marginalization: a longitudinal cohort study

Trajectories of sickness absence and disability pension in young working-age adults in Sweden

Sickness absence and disability pension (SADP) constitute a major public health concern, yet the heterogeneity in the developmental trajectories of SADP remains poorly understood. We aimed to identify trajectories of SADP in an observational cohort study of 12,721 Swedish twin individuals, born 1975-1986, who were initially invited to health screening surveys in 2005. Through linkage to nationwide registries, individuals were prospectively followed regarding annual days of SADP from 2006 to 2020. Using group-based trajectory modeling, we identified three distinct SADP trajectories in the total sample: 'high-increasing' (4%), 'low-increasing' (13%), and 'low-constant' (83%). Next, using multinomial logistic regression, we found that mental health-related factors such as neurodevelopmental conditions and common mental disorders were strongly associated with the high-increasing and low-increasing SADP trajectories. Furthermore, increasing age, female sex, low/medium educational level, and blue-collar work were found to be associated with higher odds of belonging to the high-increasing and low-increasing SADP trajectories. We did not find any effect of genetic similarity. Overall, close to every fifth individual showed rising SADP trajectories over time. Research is warranted to address the specific support needs of vulnerable young people struggling with mental health conditions, and to identify any actionable barriers to facilitate labor market integration.

Adult mental health outcomes of adolescent depression and co-occurring alcohol use disorder: a longitudinal cohort study

Depression and alcohol use disorder (AUD) are frequently co-occurring in adolescence, which often goes undetected in routine care. While this may potentially compromise treatment effectiveness and lead to a less favourable long-term prognosis, few longitudinal studies have followed this group into adulthood. The aim of this study was to explore the risk for adult depression, anxiety disorders, suicidality, and AUD in adolescents with concurrent depression and AUD. The study was based on the Uppsala Longitudinal Adolescent Depression Study (ULADS), a Swedish prospective cohort study. Diagnostic interviews were conducted in adolescence (age 16-17) and adulthood (around age 30). Adolescents with concurrent depression and AUD (n = 38) were compared with peers having only depression (n = 189) or neither of the conditions (n = 144). Logistic regression was used to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Adolescents with concurrent depression and AUD were more likely than their non-affected peers to experience adult depressive episodes (aOR, 5.33; 95% CI, 2.22-12.83), anxiety disorders (4.05; 1.77-9.27), suicidality (5.37; 2.28-12.66), and AUD (7.68; 2.59-22.81). Notably, 34% of adolescents with both depression and AUD subsequently experienced both these conditions as adults, compared to 7% of adolescents with only depression. Adolescents suffering only from depression were less likely than those with both conditions to experience suicidality (0.44; 0.21-0.95) and AUD in adulthood (0.18; 0.07-0.44). These findings underscore the clinical imperative to identify adolescents with this comorbidity. Recognition of the poor long-term prognosis can inform targeted interventions for this vulnerable group, ultimately improving health and well-being throughout the life course.

From air to mind: unraveling the impact of indoor pollutants on psychiatric disorders

Epidemiological evidence from the past 20 years indicates that environmental chemicals brought into the air by the vaporization of volatile organic compounds and other anthropogenic pollutants might be involved, at least in part, in the development or progression of psychiatric disorders. This evidence comes primarily from occupational work studies in humans, with indoor occupations being the most important sources of airborne pollutants affecting neural circuits implicated in mood disorders (e.g., major depressive disorder and bipolar disorder). The current mini review brings together recent findings of indoor airborne pollution from different fields of research, including genetics, neuropathology, and neuroimaging, for gauging underlying physiological mechanisms leading to emotional disturbances that impact nearly all aspects of human behavior. A better understanding of how indoor airborne pollutants affect brain neurons to augment clinical symptoms associated with psychiatric disorders will undoubtedly be useful in the subsequent treatment of patients with major depressive and/or bipolar disorders. This article is part of the themed issue, "Understanding the Link Between Environmental Pollutants, Brain & Behavior."

Unemployment and associations with diagnosed health problems in the Norwegian GP-DEP study: a repeated cross-sectional register study (2010-2016)

Introduction

While differences in mental health between recipients and non-recipients of unemployment benefits are well known, it is not known whether such differences exist for musculoskeletal and cardiovascular health problems. This study examined the difference in registry-based diagnoses between short term, long term and non-recipients of unemployment benefits in the Norwegian working-age population and further examined if these associations differed by educational level.

Methods

A cross-sectional repeated register study comprising all working-age individuals (age 21-67 years) with pensionable income in Norway in the period 2010 (N=2 610 956) to 2016 (N=2 791 103). Data were retrieved from the Norwegian population registry, the Education Database, the Database of Social Insurance and the Control and Reimbursement of Health Care Claims Database and linked on individual level. Associations between recipients and non-recipients of unemployment benefits and physician-certified diagnoses were examined with Poisson regression with robust variance estimates (relative risk (RR) with 95% CI) and stratified by education.

Results

Both short-term and long-term recipients of unemployment benefits were associated with an increased likelihood of having one or more musculoskeletal, psychological or cardiovascular diagnoses compared with non-recipients. The strength of the associations increased with cumulative days of unemployment, with adjusted RRs (95% CIs) for musculoskeletal disorder 1.7 (1.7 to 1.7); psychological diagnoses 2,.2 (2.2 to 2.3); subgroup depression 3.3 (3.2 to 3.3) and for cardiovascular disease 1.3 (1.3 to 1.3) compared with non-recipients. Among highly educated people, the association between unemployment and having a diagnosis was stronger than among unemployed with medium and low education.

Conclusions

Unemployment benefits recipiency were associated with musculoskeletal, psychological and cardiovascular diagnoses, and the strength of the association increased with higher education. The direction of the relationship could not be determined in this study.

Pathways from school to work: A sequence analysis of non-engaged youth

INTRODUCTION

Research on heterogeneous pathways in school-to-work transitions (SWT), particularly longitudinal research, has been limited, as have empirical studies examining effective interventions for facilitating multiple SWT pathways among non-engaged youth (NEY), who are generally at risk of being not in education, employment, or training (NEET).

METHODS

To develop a typology of SWT pathways, we conducted sequence analysis with longitudinal data from a sample of 630 NEY aged 14-29 (M = 19.78; 63.65% males) in Hong Kong during a 22-month period beginning in September 2020. We also performed multinomial logistic regressions to assess the impact of career and life development (CLD) interventions on SWT outcomes.

RESULTS

Our analysis yielded a fivefold typology of SWT pathways: the Employment/Entrepreneurship cluster (31.27%), the Vocational Education and Training cluster (13.49%), the Generic Education cluster (16.83%), the Serious Leisure Development cluster (15.24%), and the long-term NEET cluster (23.17%). NEY in the intervention group receiving CLD services, inspired by the expanded notion of work (ENOW) and youth development and intervention framework (YDIF), demonstrated significantly higher likelihoods of being in the Employment/Entrepreneurship (OR = 34.5, 95% CI [10.53, 105.08]), Generic Education (OR = 3.74, 95% CI [1.81, 7.74]), Vocational Education and Training (OR = 1.55, 95% CI [1.05, 6.26]), and Serious Leisure Development (OR = 1.77, 95% CI [1.04, 4.46]) clusters than the long-term NEET cluster.

CONCLUSIONS

Our findings highlight the dynamic, heterogeneous nature of NEY's CLD journeys, including that CLD interventions based on ENOW-YDIF have had a beneficial effect on NEY's multiple SWT pathways.

Adolescent Psychiatric Inpatient Episodes and Subsequent Labor Market Trajectories

PURPOSE

Adolescents with psychiatric disorders are known to be more often not in education, employment, or training (NEET) in young adulthood than their peers. However, since most of the available evidence is based on cross-sectional measurement of NEET, there is less evidence on the processes underlying these differences in labor market disadvantage. We assessed these processes by examining transitions between NEET and non-NEET states across young adulthood and the differences in these transitions by adolescent psychiatric inpatient treatment.

METHODS

We used longitudinal register data on all individuals born in Finland in 1980-1984 (N = 315,508) to identify psychiatric inpatient episodes between ages 10 and 19 and NEET between ages 20 and 34. We modeled the transitions between NEET and non-NEET states and the impact of psychiatric disorders on these transitions with multistate models.

RESULTS

Individuals who had psychiatric inpatient episodes in adolescence started their labor market careers as NEET twice as often as their peers. They were also more likely to transition into NEET states and less likely to transition out of NEET. In total, individuals with a history of psychiatric episodes spent from 1.8 to 6.9 more years as NEET between the ages 20 and 34 than their peers, depending on sex, baseline NEET, and diagnostic group.

DISCUSSION

Adolescents with severe psychiatric disorders are highly vulnerable in terms of labor market outcomes throughout their early adulthood. Supportive measures are required both at the start of employment trajectories and during later career stages.

Feasibility, acceptability, and depression outcomes of a randomized controlled trial of Mindful Self-Compassion for Teens (MSC-T) for adolescents with subsyndromal depression

INTRODUCTION

Adolescents are experiencing high rates of depressive symptoms, with negative consequences to their long-term health. Group-based, mindful self-compassion programs show promise in mitigating the development of more significant depression in at-risk adolescents. However, the lack of well-designed, active control conditions has limited the ability to examine the efficacy of such interventions.

METHODS

Fifty-nine adolescents (Mage  = 15.81, 70% female) with subsyndromal depressive symptoms from the Southeastern US were randomized to group-based Mindful Self-Compassion for Teens (N = 30) or a newly developed active control Healthy Lifestyles group (N = 29) during 2018 and 2019. Participants attended 8 weekly "main" sessions followed by 6 monthly continuation sessions. The feasibility and acceptability of participation in both groups were measured using attrition, attendance, credibility, and satisfaction data. Depression scores were collected weekly, and self-compassion scores were collected five times across 36 weeks.

RESULTS

Both groups were equally feasible and acceptable during the 8-week program period; however, monthly continuation sessions were poorly attended in both groups. The risk of developing clinically significant depression was 2.6 times higher in the control group compared with the self-compassion group (p = .037) across 36 weeks. Depression significantly decreased in the self-compassion group, while it significantly increased in the control group. Both groups increased significantly in reports of self-compassion. These findings are on par with results noting the efficacy of cognitive-based interventions for high-risk adolescents; follow-up studies with larger sample sizes should be conducted to confirm these findings.

CONCLUSIONS

Initial examination suggests Mindful Self-Compassion for Teens programming is feasible, acceptable, and efficacious in preventing the development of clinically significant depression in adolescents with subsyndromal depression. Future studies may benefit from refinements to the self-compassion measurement and/or the attention control condition; moreover, larger sample sizes are needed to confirm results.

Longitudinal trajectories of sickness absence among young adults with a history of depression and anxiety symptoms in Sweden

BACKGROUND

Depression and anxiety are associated with increased risk of sickness absence (SA), yet the developmental patterns of SA remain unclear. We aimed to identify trajectories of SA in young adults with depression and/or anxiety, accounting for sociodemographic and occupational factors.

METHODS

Longitudinal study of 1445 twin individuals with elevated depressive/anxiety symptoms in late adolescence or young adulthood (age range: 19-30), assessed in Swedish surveys completed in 2005. Through linkage to nationwide registries, individuals were prospectively followed from 2006 to 2018. The outcome included consecutive annual days of SA, which were analyzed using group-based trajectory modeling. Multinomial logistic regression estimating odds ratios (OR) with 95 % confidence intervals (CI) was used to examine associations of age, sex, and educational level with the resulting SA trajectories.

RESULTS

Four distinct SA trajectories were identified in the total sample: 'high-increasing' (6 %), 'low-increasing' (12 %), 'high-decreasing' (13 %), and 'low-constant' (69 %). Increasing age was associated with higher odds of belonging to the low-increasing trajectory (OR = 1.07, 95 % CI = 1.02-1.12). Women had higher odds of belonging to the low-increasing trajectory (OR = 1.67, 95 % CI = 1.10-2.53), compared with men. Higher education was associated with lower odds of belonging to high-increasing (OR = 0.34, 95 % CI = 0.22-0.54) and high-decreasing (OR = 0.59, 95 % CI = 0.43-0.81) trajectories, compared with lower education. Few differences were observed in analyses stratified by occupational sector.

LIMITATIONS

Information on potential confounders (e.g., psychiatric comorbidity, work-environment factors) was not available.

CONCLUSIONS

Among young adults with prior depression/anxiety, close to every fifth showed rising SA trajectories over time. This calls for targeted strategies to improve public mental health already at young ages.

The Mediating Roles of Future Work Self and Hope on the Association Between Perceived Social Support and Depressive Symptoms Among Chinese Vocational School Students: A Cross-Sectional Study

Purpose

Depressive symptoms are serious mental health problems, which are harmful for adolescents' physical and psychological development. Limited studies have focused on depressive symptoms of vocational high school students, who are more susceptible to mental health problems than high school students. Based on the main effect model of social support and self-regulation theory, the current study aims at exploring two potential mediating roles of hope and future work self on the relationship between perceived social support and depressive symptoms among vocational high school students by a cross-sectional study.

Participants and Methods

A total of 521 vocational high school students aged 14-21 (M= 16.45; SD= 0.91) participated in the survey. There were 266 males (51.1%) and 255 females (48.9%). The multidimensional scale of perceived social support, the future work self scale, the children's hope scale, and the center for epidemiologic studies depression scale were applied in the study.

Results

The results revealed that: (1) perceived social support, future work self, and hope were negatively related to depressive symptoms (r = -0.25 to -0.35, p < 0.001); (2) students who perceived more social support have fewer depressive symptoms (β = -0.22, p < 0.001); (3) perceived social support predicted a more salient future work self and then was associated with higher levels of hope, which in turn, was related to lower levels of depressive symptoms (β = -0.02, and 95% CI = [-0.035, -0.005]).

Conclusion

Perceived social support was the protective factor against vocational school students' depressive symptoms. More specifically, stronger perceived social support predicted a more salient future work self, which promoted high level of hope, and ultimately decreased vocational school students' depressive symptoms. The findings provide enlighten implications for interventions on depressive symptoms among vocational high school students.

Associations of Internalizing and Externalizing Problems in Childhood and Adolescence With Adult Labor Market Marginalization

Importance

Mental health problems in early life are associated with labor market marginalization, especially in youths with persistent internalizing and externalizing problems. However, previous research has not adjusted for familial (genetic and shared environmental) factors.

Objective

To examine associations of early-life internalizing and externalizing problems with adulthood unemployment and work disability, adjusting for familial factors.

Design, Setting, and Participants

This population-based prospective cohort study included Swedish twins who were born in 1985-1986 and surveyed at 4 consecutive waves across childhood and adolescence until 2005. Through linkage to nationwide registries, participants were followed up from 2006 to 2018. Data analyses were conducted between September 2022 and April 2023.

Exposures

Internalizing and externalizing problems, assessed with the Child Behavior Checklist. Participants were differentiated regarding duration of internalizing and externalizing problems (persistent, episodic, and noncases).

Main Outcomes and Measures

Unemployment (180 days or more of being unemployed) and work disability (60 days or more of being sickness absent or disability pensioned) during follow-up. Cox proportional hazards regression models were calculated to obtain cause-specific hazard ratios (HRs) with 95% CIs in the whole cohort and exposure-discordant twin pairs.

Results

Of 2845 participants, 1464 (51.5%) were female. Incident unemployment was experienced by 944 (33.2%) and incident work disability by 522 (18.3%) participants. Compared with noncases, persistent internalizing problems were associated with unemployment (HR, 1.56; 95% CI, 1.27-1.92) and work disability (HR, 2.32; 95% CI, 1.80-2.99). Similarly, compared with noncases, persistent externalizing problems were associated with unemployment (HR, 1.87; 95% CI, 1.55-2.26) and work disability (HR, 2.38; 95% CI, 1.87-3.03). Persistent cases had overall higher risks of adverse outcomes than episodic cases. After adjustment for familial factors, associations with unemployment were no longer statistically significant, whereas associations with work disability remained or were only slightly reduced.

Conclusions and Relevance

In this cohort study of young Swedish twins, familial factors explained the associations between early-life persistent internalizing and externalizing problems and unemployment; such factors were comparatively less important for the association with work disability. This suggests nonshared environmental factors may be important for the risk of future work disability among young individuals with persistent internalizing and externalizing problems.

Sickness absence among young employees in private and public sectors with a history of depression and anxiety

The aim was to investigate occurrence and duration of sickness absence (SA) among young employees with previous depression/anxiety in private and public sectors. This population-based prospective study included 11,519 Swedish twin individuals of age 19-29 years that were followed regarding SA during 2006-2016. Data on previous depression/anxiety came from two screening surveys in 2005. Data on SA and employment sector were received from national registries. Descriptive statistics and logistic regression were used, also controlling for familial factors. Proportion of employees with SA was significantly higher among those with, as compared to those without, previous depression/anxiety, regardless the employment sector. Individuals with previous depression/anxiety had increased risk for future SA, in both private (OR 2.25, 95% CI 1.90-2.66) and public sectors (OR 2.10, 95% CI 1.73-2.54). Familial factors played a role in the association among employees in the private sector. A higher proportion of long-term SA was observed among employees with previous depression/anxiety in the private as compared to the public sector. To conclude, previous depression/anxiety tends to increase risk for SA among young employees in both employment sectors, whereas long-term SA seemed to be more prevalent among those in the private as compared to the public sector.

Nature-Based Meditation, Rumination and Mental Wellbeing

Novel approaches for children and young people (CYP) in the prevention and intervention of mental illness are needed and nature-based interventions (NBI) may be clinically useful. This proof-of-principle study tested the effects of a novel brief nature-based meditation on rumination, depressive symptoms and wellbeing in young people. Sixty-eight university students were randomised to one of three conditions: active control (n = 23), indoor meditation (n = 22) or nature-based meditation (n = 23). Participants completed self-report measures on state and trait rumination post intervention and depression and wellbeing at a 2-week follow-up. Depressive rumination significantly decreased post intervention in the nature condition and depressive symptoms improved for both intervention groups. Wellbeing only significantly improved at follow-up in the nature condition. Nature condition participants demonstrated one minimal clinically important difference (MCID) for wellbeing at follow-up. Depressive symptoms for this condition were below the clinically significant threshold for depression. The number needed to treat (NNT) analysis suggested that two to five young people would need to complete the intervention. Preliminary evidence suggests NBIs, such as the one in the present study, can reduce depressive rumination and symptoms and improve wellbeing. Replication with larger clinical samples is required to substantiate findings.

Correlates and Predictors of Chronicity among Adolescents Living in Puerto Rico With a History of Depressive Symptoms

Chronic depression (CD) among Hispanic/Latina(o) youths has been understudied, although chronicity is the biggest risk factor for treatment-resistant depression. We examined CD correlates and predictors among 291 youths (aged 12-18 years) living in Puerto Rico with a history of depressive symptoms. They completed the Children's Depression Inventory (CDI), the Depressive Symptoms Spectrum Assessment Inventory (DSSAI), and the Brief Structured Diagnostic Measure for Depression. We explored CD correlates using Odds Ratios adjusted for CDI-Total scores. With multiple logistic regression, we identified optimal predictors of a history of chronic depressive symptoms (HCDS) or any chronic depressive disorder (HACDD). Living zone (rural), history of depressive disorder, household size (< 4), age of onset of symptoms (< 13 years), death/suicidal thoughts at the first episode, antidepressants use, and scores ≥ 84^th percentile in the DSSAI-Anhedonia subscale, accounted for 37% of HCDS variance. The latter five variables and socioeconomic status (lower-middle/low) best distinguished HACDD and episodic disorders (R ² = .331). Identifying factors that distinguish chronic and episodic depression among Hispanic/Latina(o) youths may help to improve their diagnosis, access to and quality of care, as well as treatment selection, tailoring, and outcomes.
