Although discrimination has been validated to be negatively related to mental health, little is known about the effect of hukou-based discrimination by teachers on depression among migrant adolescents in China. The mediating and moderating mechanisms underlying this association are also unknown. Based on a nationally representative sample of migrant adolescents, this study examined whether school engagement mediated the association between teacher discrimination and depression, and whether the direct and mediating effects were moderated by poverty. Our sample comprised 2041 migrant adolescents (46.2% female) from the first two waves of the China Education Panel Survey (CEPS). The results indicated that teacher discrimination (T1) was positively associated with depression (T2). Emotional engagement with school (T1) rather than cognitive engagement with school (T1) partially mediated this association. Moreover, poverty status moderated the direct association between teacher discrimination and migrant adolescents' depression as well as the indirect relationship via emotional school engagement. Specifically, the direct and indirect effects were stronger for migrant adolescents living in poverty than they were for their non-impoverished counterparts. Contributions and implications of this study are discussed. [ABSTRACT FROM AUTHOR]

Background: Traumatic experiences often give rise to an increased risk of anxiety problems in adolescents. This study investigated the anxiety prevalence in adolescent earthquake survivors and the effect of secondary stressors such as bullying, poverty, or being "left behind" by parents working in the cities.Methods: This cross-sectional study was conducted three years after the 2013 Ya'an (China) earthquake on 6,132 adolescents aged 9 to 18 years from 11 public schools in three severely earthquake affected counties. The participants completed self-report questionnaires that assessed anxiety, earthquake exposure, poverty level, left-behind duration and bullying.Results: Separation anxiety (38.7%) and panic symptoms (32.2%) were found to be the primary contributors to anxiety in this adolescent sample. The regression and structural equation modeling indicated that adolescents who had suffered from high earthquake exposure, peer bullying, being left-behind, or poverty were more likely to report problems in all anxiety subcategories, with females reporting more anxiety symptoms than males. The likelihood of all anxiety disorders except separation anxiety was found to increase with age.Conclusions: This study highlighted the need for post-disaster interventions aimed at minimizing post-earthquake adversity such as peer bullying and specialized psychological services that target subgroups that might be more susceptible to anxiety-related emotional problems. The results could be used to identify possible markers for anxiety problems in children who had not experienced any major traumas. [ABSTRACT FROM AUTHOR]

Objective: Sedentary behaviour (SB) is harmful for health and well-being and may be associated with depression. However, little is known about the correlates of SB in people with depression. Thus, we investigated SB correlates among community-dwelling adults with depression in six low- and middle-income countries.Methods: Cross-sectional data from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. The analysis was restricted to those with DSM-IV Depression or receiving depression treatment in the last 12 months. Self-reported time spent sedentary per day was the outcome. High SB was defined as ≥8 hours of SB per day. The correlates (sociodemographic and health-related) of SB were estimated by multivariable linear and logistic regression analyses.Results: In 2375 individuals with depression (mean age=48.0 years; 60.7% female), the prevalence of high SB was 11.1% (95%CI=8.2%-14.9%), while the mean (±SD) time spent sedentary was 215 (±192) minutes per day. Socio-demographic factors significantly associated with high SB were older age and being unmarried, being male and being unemployed. In other domains, no alcohol consumption, current smoking, mild cognitive impairment, bodily pain, arthritis, stroke, disability, and lower levels of social cohesion, COPD, visual impairment, and poor self-rated health was associated with greater time spent sedentary.Conclusion: Our data suggest that future interventions seeking to reduce SB among individuals with depression may target at risk groups based on identified sociodemographic correlates while the promotion of social cohesion may have the potential to increase the efficacy of future public health initiatives. From a clinical perspective, bodily pain and somatic co-morbidities need to be taken into account. [ABSTRACT FROM AUTHOR]
