Dualized Labor Market and Polarized Health: A Longitudinal Perspective on the Association between Precarious Employment and Mental and Physical Health in Germany

This study analyzes the longitudinal association between precarious employment and physical and mental health in a dualized labor market by disaggregating between-employee and within-employee effects and considering mobility in precariousness of employment. Analyses were based on the German Socio-Economic Panel from 2002 to 2018 considering all employees ages 18 to 67 years (n = 38,551). Precariousness of employment was measured as an additive index considering working poverty, nonstandard working time arrangements, perceived job insecurity, and low social rights. Health outcomes were mental and physical health. Random effects models were used and controlled for sociodemographic and socioeconomic variables. Results indicated that the association between precariousness of employment and mental and physical health is mainly based on between-employee differences and that prolonged precariousness of employment or upward or downward mobility are associated with poor health. We found evidence of polarization in health by precariousness of employment within a dualized labor market.

Child Maltreatment and Substance Use: A Behavior Genetic Analysis

Child maltreatment is a pervasive social problem often perpetuated by family members and is related to a wide array of negative life outcomes. Although substance use is an outcome commonly associated with experiences of child maltreatment, not all individuals who experience maltreatment struggle with such issues. Many individuals can positively adapt to experiences of maltreatment based on levels of resilience and susceptibility. Research suggests that genetic differences may partly explain why negative outcomes develop for some, but not for others. Few studies have examined the extent to which genetic and environmental factors influence the longitudinal association between child maltreatment and varying forms of substance use, leaving a fundamental gap in our current understanding of this association. The current study aims to address this gap by analyzing a sample of twins from the National Longitudinal Study of Adolescent to Adult Health (Add Health). Findings from a series of univariate and bivariate biometric models reveal that the longitudinal associations between maltreatment, cigarette use, and marijuana use are accounted for by additive genetic and nonshared environmental factors. Moreover, the magnitude of the contribution varies across unique subgroups of cigarette and marijuana use. Directions for future research and theoretical implications are discussed.

Psychological Well-Being and Social Competence During Adolescence: Longitudinal Association Between the Two Phenomena

Despite previous research on adolescence points to an association between social competence and well-being, limited knowledge is available. Most studies have documented a one-way pattern of influence, although reciprocity has also been suggested. However, they mainly use a cross-sectional design, do not focus on psychological well-being, and do not use integrative and multidimensional constructs. From a eudaimonic approach to well-being and situation-specific to social competence, this study aimed to: (1) explore the factorial structure of the dimensions assessed; (2) analyse the longitudinal relationship between psychological well being and social competence during adolescence; and (3) examine psychological well-being and social competence levels and their stability over time. The sample consisted of 662 adolescents aged between 14 and 16 years old (Time 1 Mage = 14.63; SD = 0.64; 51% girls). Structural equation analysis confirmed the existence of second-order factors, showing evidence of a positive and bidirectional relationship between psychological well-being and social competence. Results also revealed medium–high levels in both constructs, which remained stable over time. These findings highlight the importance of promoting both psychological well-being and social competence to achieve successful, healthy development.

What Could Interfere with a Good Night’s Sleep? The Risks of Social Isolation, Poor Physical and Psychological Health among Older Adults in China

This study provides one of the first population-based investigations of the longitudinal association between social isolation and sleep difficulty among older adults in China. We analyzed three waves of longitudinal data from the China Longitudinal Aging Social Survey (2014–2018), in which 8456 respondents contributed 16,156 person-year observations. Results from multilevel logistic regression models showed that social isolation was related to a higher risk of sleep difficulty. We also found that socially isolated older adults were more likely to report higher levels of depressive symptoms, a greater prevalence of loneliness and pain, and more chronic diseases compared to their socially integrated counterparts, which in turn increased their risks of sleep difficulty. Moreover, socially isolated older adults with chronic diseases were particularly vulnerable to the risk of sleep difficulty. These findings provide helpful guidance for policymakers and practitioners to design effective intervention strategies to help older adults with sleep problems.

Mortality associated with nonrestorative short sleep or nonrestorative long time-in-bed in middle-aged and older adults

Associations of sleep duration with human health could differ depending on whether sleep is restorative. Using data from 5804 participants of the Sleep Heart Health Study, we examined the longitudinal association of sleep restfulness combined with polysomnography-measured total sleep time (TST) or time in bed (TIB), representing different sleeping behaviors, with all-cause mortality. Among middle-aged adults, compared with restful intermediate TST quartile, the lowest TST quartile with feeling unrested was associated with higher mortality (hazard ratio [HR], 1.54; 95% confidence interval [CI] 1.01–2.33); the highest TST quartile with feeling rested was associated with lower mortality (HR, 0.55; 95% CI 0.32–0.97). Among older adults, the highest TIB quartile with feeling unrested was associated with higher mortality, compared with restful intermediate TIB quartile (HR, 1.57; 95% CI 1.23–2.01). Results suggest a role of restorative sleep in differentiating the effects of sleep duration on health outcomes in midlife and beyond.

Association Between Changes in Depressive Symptoms and Hazardous Drinking: Findings From the Korea Welfare Panel Study (2013–2018)

Objective: This study aimed to evaluate the longitudinal association between changes in depressive symptoms and hazardous drinking among South Korean adults.Participants/Methods: This study was conducted using a sample drawn from participants enrolled in the Korea Welfare Panel Study (KoWePS) from 2013 to 2018. Hazardous drinking was defined as a score of 11 points for men and seven points for women on the Korean version of the Alcohol Use Disorders Identification Test. Depressive symptoms were evaluated using an 11-item version of the Center for Epidemiologic Studies Depression Scale. A generalized estimating equation model was used to analyze the association between changes in depressive symptoms and hazardous drinking.Results: Of the 12,878 people registered with KoWePS and without follow-up losses from 2013 to 2018, a total of 2,341 were included in this study, excluding those under the age of 19 and those with missing data. Persistent depressive symptoms (men, odds ratio [OR]: 2.20, 95% confidence interval [CI]: 1.48–3.21; women, OR: 2.64, 95% CI: 1.66–4.22) and the changes from non-depressive symptoms to depressive symptoms (men, adjusted OR: 2.18, 95% CI: 1.80–2.64; women, OR: 1.71, 95% CI: 1.27–2.29) increased the likelihood of hazardous drinking.Conclusions: Persistent depressive symptoms and changes from non-depressive to depressive symptoms are associated with increased prevalence of hazardous drinking. This suggests that an evaluation of the underlying mental illness or emotion should be made when counseling for abstaining from alcohol for chronic drinkers or the general public.

Children’s oppositional defiant disorder symptoms make parents difficult to be nice: Longitudinal association among parent emotion regulation, child emotion regulation and children’s oppositional defiant disorder symptoms in Chinese children with oppositional defiant disorder

The current study aims to clarify the longitudinal relations among parent emotion regulation (ER), child ER, and children’s oppositional defiant disorder (ODD) symptoms. In the current study, parents of 275 children (195 boys, 70.1%) with ODD symptoms ( Mage = 9.32 years, SD = 1.64) reported their ER using the Difficulties in Emotion Regulation Scale, child ERs using the Emotion Regulation Checklist, and children’s ODD symptoms using the eight symptoms indicated in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) at three time points (T1, T2, and T3) within 2 years. Results indicated the longitudinal relationships between parent ER and children’s ODD symptoms were directly influenced by each other. Children’s ODD symptoms had important effects on both child ER and parent ER. Findings suggested that to reduce children’s ODD symptoms, it is necessary not only to improve child ER but also to improve parent ER.
