Depression and Perceived Social Support among Unemployed Youths in China: Investigating the Roles of Emotion-Regulation Difficulties and Self-Efficacy.

In recent years, the issue of youth unemployment has begun to emerge in China. Unemployed young people are at high risk of depression and other mental health problems. The present study investigates influential factors related to depression and examines the possible mediating effects of difficulties in emotion regulation and self-efficacy between perceived social support and depressive symptoms among unemployed youths in China. Through community recruitment, 511 unemployed young people from Shanghai participated in this cross-sectional survey. The results demonstrate that the prevalence of probable depression in the sample was 49.3% (95% CI: 45.0-53.7%). Moreover, we found that both the perceived social support and self-efficacy were significant negative predictors of depression, whereas difficulties in emotion regulation were positive predictors of depression. In addition, the analysis results indicate that difficulties in emotion regulation and self-efficacy partially mediate the relationship between perceived social support and depression. Overall, this cross-sectional study reveals that depression and mental health problems among China's unemployed youths are concerning while identifying emotion-regulation difficulties as a risk factor for these and social support and self-efficacy as protective factors, all of which warrant our attention in preventing and intervening with cases of youth depression.

Progression of myopia in a natural cohort of Chinese children during COVID-19 pandemic.

PURPOSE: To determine myopia progression in children during the COVID-19 and the related factors associated with myopia. METHODS: All subjects underwent three-timepoint ocular examinations that were measured in July 2019, January, and August 2020. We compared the changes in uncorrected visual acuity (UCVA), mydriatic spherical equivalent (SE), and axial length (AL) between two periods (before and during COVID-19). A questionnaire was performed to investigate risk factors for myopia. RESULTS: Compared with before the COVID-19, the mean (S.D.) myopia progression during the COVID-19 was significantly higher in right eyes (- 0.93 (0.65) vs. - 0.33 (0.47) D; p < 0.001). However, the differences in UCVA changes and the axial elongation between two periods were clinically insignificant. Through logistic regressive analysis, we found the difference of the SE changes was associated with the baseline AL (P = 0.028; 95% confidence interval [CI], 1.058, 2.632), online education (P = 0.02; 95% CI, 1.587, 8.665), and time of digital screen (p < 0.005; 95% CI, 1.587, 4.450). CONCLUSIONS: Children were at higher risk of myopia progression during COVID-19, which was associated with the baseline AL, the longtime online learning, and digital screen reading.
