Childhood and adolescence are critical periods for physical and mental development; thus, they are high-risk periods for the occurrence of mental disorders. The purpose of this study was to systematically evaluate the association between bullying and depressive symptoms in children and adolescents. We searched the PubMed, MEDLINE and other databases to identify studies related to bullying behavior and depressive symptoms in children and adolescents. A total of 31 studies were included, with a total sample size of 133,688 people. The results of the meta-analysis showed that the risk of depression in children and adolescents who were bullied was 2.77 times higher than that of those who were not bullied; the risk of depression in bullying individuals was 1.73 times higher than that in nonbullying individuals; and the risk of depression in individuals who bullied and experienced bullying was 3.19 times higher than that in nonbullying-bullied individuals. This study confirmed that depression in children and adolescents was significantly associated with being bullied, bullying, and bullying-bullied behavior. However, these findings are limited by the quantity and quality of the included studies and need to be confirmed by future studies.

Introduction: Nurse job satisfaction, defined as the positive emotional state experienced by nurses regarding their profession, factors related to job performance and outcomes, can affect their career planning and development. Grit, defined as an individual’s relentless effort and enduring enthusiasm for long-term goals, is essential for developing nurses’ competence, increasing job satisfaction, and reducing the willingness to leave the profession. The present study aims to explore the correlation between grit and job satisfaction, whether perceived stress could act as a mediator of the relationship and whether optimism moderated the mediating effect among nurses working in hospitals in southwest China.Methods: The cross-sectional study utilized self-reported data gathered from 709 nurses in southwest China. To analyze mediating and moderating effects, bootstrapping regressions were conducted.Results: Perceived pressure mediated the relationship between grit and job satisfaction (indirect effect = 0.195, 95%CI [0.145,0.250]). Furthermore, moderated mediated analysis revealed that optimism moderated grit’s impact on perceived stress (moderating effect = 0.036, 95% CI [0.010, 0.061]).Discussion: Low levels of grit might reduce nurses’ job satisfaction as their perceived stress levels increase. However, optimism among nurses could diminish this negative effect. Nursing managers should actively seek to improve the grit and optimism of hospital nurses while reducing their perceived pressure, thereby improving job satisfaction.

Objectives: The purpose of this study was to examine the incidence of depressive symptoms, and determine if baseline risk factors conferred a risk for incident depressive symptoms in nationally representative sample of mid-aged and elderly Chinese adults.Design: This study was a secondary analysis of a prospective cohort from a nationally representative sample.Setting: Community samples were recruited from the baseline survey of the China Health and Retirement Longitudinal Study. A four-stage, stratified, cluster probability sampling strategy was used, which included 10 257 households with members aged 45 years or older and their spouse.Participants: A total of 11 533 participants free of depressive symptoms at baseline were identified, and 10 288 were re-examined in either the first and/or the second follow-up surveys. The current analysis was conducted among the 10 288 participants.Primary and secondary outcome measures: Depressive symptoms were measured by the Center for Epidemiological Studies Depression Scale short form.Results: The findings showed that the incidence of depressive symptoms in a 4-year follow-up was as high as 22.3%. The incidence was much higher in rural areas (25.7%) and in women (27.9%). Furthermore, participants with 1 hour longer of night-time sleep had a 10% lower risk of developing depressive symptoms. Compared with individuals who perceived their health status as poor, those who perceived their health status as excellent had a 62% lower risk of developing depressive symptoms. In addition, having diabetes (OR=1.19), chronic kidney disease (OR=1.32), chronic digestive disorders (OR=1.15) and arthritis (OR=1.43) at baseline increased the risk of depressive symptoms. However, baseline body mass index was not associated with the subsequent depressive symptoms in this population.Conclusions: This study highlights the importance of developing an appropriate screening test to identify depressive symptoms for those who are vulnerable and ensure these individuals can receive early interventions for depressive symptoms.

Grit is defined as perseverance and passion for long-term goals, and it may affect the stability of the nursing workforce and the physical and mental health of nurses continuously. Meaning in life has received considerable attention from scholars, which is an important component in positive psychology. This study aimed to delve into the relationship between grit and the meaning in life of Chinese nurses. Additionally, we also sought to prove the chain mediating effect of social support and hope on this relationship. An online questionnaire survey was used to collect data from 704 Chinese nurses using the self-made demographic questionnaire with Short Grit Scale (Grit-S), the Perceived Social Support Scale (PSSS), Adult Dispositional Hope Scale (ADHS), and Meaning in Life Questionnaire (MLQ). Moreover, Process version 3.3 plug-in SPSS 25 was used to test the mediation effect between variables. The results showed a strong positive relationship between grit and meaning in life and verified the mediating effect of social support and hope on grit and meaning in life. The results also confirmed the chain mediating model between grit, social support, hope, and meaning in life.
