Abstract Depressive symptoms among adolescents are common in the world, depressive symptoms could increase the risk of physical and mental health, interpersonal relationship, social adaption in later life. Hence, the prevention of depressive symptom among adolescents have been valued by scholars and plenty studies have been conducted from the perspective of gene, environment and the inter connectivity between gene and environment. The environment adolescents faced can be divided into family environment, school environment and social environment. This study reviews the controllable factors in three environments and provides references for the prevention and control of depressive symptoms among adolescents.

Objective: To explore the chain mediating effect of regulatory emotional self efficacy and positive psychological capital on resilience and the mental health of college students. Methods: A total of 809 college students of Chaohu University were selected and were administered with the the Self report Symptom Invertory, Symptom Checklist,90 (SCL-90), Connor Davidson Resilience Scale (CD-RISC), Regulatory Emotional Self efficacy Scale (RES-C) and Positive Psychological Capital Questionnaire (PPQ). Multiple linear regression analysis was performed, taking resilience, regulatory emotional self efficacy and positive psychological capital as independent variables and the mental health of college students as dependent variables, meanwhile test the intermediary effect. Results: Differences were found in resilience(3.52±0.55,3.27±0.42), regulatory emotional self efficacy(3.58± 0.59 ，3.32±0.57), positive psychological capital(4.74±0.77，4.49±0.76) and mental health(158.66±33.01，176.53±34.73) among college students with different sources(urban and rural)( t =55.82，39.22，21.28，-54.14， P <0.05). Resilience, regulatory emotional self efficacy and positive psychological capital were significantly associated with the severity of mental health of college students( R 2= 0.21, P <0.01). Regulatory emotional self efficacy and positive psychological capital played a significant chain mediating role between resilience and poor mental health( effect =-0.03, P <0.05), and the mediating effect accounted for 39.3% of the total effect. Conclusion The mental health of college students can be improved by strengthening levels of resilience and enhancing regulatory emotional self efficacy, and constructing positive psychological capital could contribute to the association between resilience and mental health.

Objective: To understand relationship of positive and negative peer events with mental health problems among college students, so as to provide a scientific basis for improving mental health level of college students. Methods: A total of 1 640 freshmen to juniors were randomly selected from two universities in Anhui Province from October to November 2023 by a combination of convenience sampling and cluster random sampling method. The positive and negative peer events, self perceived loneliness and stress levels, anxiety and depression symptoms of students were investigated by using the questionnaire star online. Group comparisons were conducted by using analysis of variance and Chi square test, and multivariate binary Logistic regression and linear regression were used to analyze relationship of positive and negative peer events with mental health problems among college students. Results: About 35.4% of college students reported that they experienced at least one type of negative peer events, and 91.3% reported that they experienced at least one type of positive peer events. After controlling for covariates,multivariate regression analysis found that experiencing 1, ≥2 types of negative peer events were positively correlated with loneliness scores of college students ( β = 1.36,4.04), as well as an increased risk of anxiety symptoms ( OR =2.24,4.33) and depression symptoms ( OR =2.19,4.01); and experiencing ≥2 types of negative peer events was positively correlated with stress scores of college students ( β =1.12)( P <0.05). Experiencing 5-6 and 7 types of positive peer events were negatively correlated with loneliness scores of college students ( β = -1.79, -2.44) and stress ( β =-0.75, -1.12); and experiencing 7 types of positive peer events were associated with a lower risk of anxiety symptoms ( OR =0.74) and depressive symptoms ( OR =0.80) ( P <0.05). The number of negative peer events was positively correlated with loneliness scores ( β =0.80) and stress scores( β =0.24), as well as the risk of anxiety symptoms ( OR =1.30) and depressive symptoms ( OR =1.27) among college students ( P <0.05). The number of positive peer events involved was negatively correlated with loneliness scores( β =-0.39) and stress scores( β =-0.19), as well as the risk of anxiety ( OR =0.92) and depressive symptoms ( OR =0.93) among college students ( P <0.05). The analysis of the moderating effect found that in different groups of positive peer events, reporting 1, ≥2 negative peer events were positively correlated with loneliness scores of college students ( β=1.08- 4.96), as well as an increased risk of anxiety symptoms ( OR =1.79-6.20) and depression symptoms ( OR =1.78-6.77) ( P <0.05); and β and OR coefficients were highest in the group reporting 0-4 types of positive peer events, followed by the group reporting 5-6 types of positive peer events, with lowest coefficients in the group reporting 7 types of positive peer events. Conclusions Negative peer events are positively correlated with psychological problems in college students, and positive peer events are negatively correlated with mental health problems. Positive peer events could alleviate the impact of negative peer events on mental health problems.

Objective: To summarize the existing cohort study evidence between adverse childhood experience(ACEs) and adolescent depression, to explore the influence of ACEs on adolescent depression, so as to provide evidence for the prevention of adolescent depression. Methods: Chinese and English literatures on the cohort study on the correlation between ACEs and adolescent depression published by WanFang, VIP databases, CNKI, CBM, PubMed and Web of Science were searched. We only selected orginal articles that their either reported on Chinese and English retrieval words of "adverse childhood experiences" "ACE" "abuse" "maltreat" "mistreat" "neglect" "bully" "bullying" "family dysfunction" "family violence" "adversities" "trauma" "victimization" "victim" "adverse events" "adverse experiences" "longitudinal" "follow-up" "prospective" "cohort" "depression" "depressive". Meta-analysis was performed on the literatures that met the inclusion criteria, and statistical analysis was conducted using Stata software. Results: Twelve references (11 in English and 1 in Chinese) were included in the Meta-analysis, and the results showed that ACEs were positively correlated with adolescent depression (pooled OR=1.75，95%CI=1.43-2.15). Among them, The effect of neglect was most prominent (pooled OR=2.42, 95%CI=1.31-4.46) while the influence of abuse was least strong (pooled OR=1.77, 95%CI=1.25-2.52). The pooled odds ratio associated with bully was 2.09 with the 95% confidence intervals from 1.38 to 3.16. The pooled odds ratio of boys is greater than girls(boys: pooled OR=3.77, 95%CI=2.31-6.15; girls: pooled OR=1.44, 95%CI=1.04-2.01). Funnel plot and Egger test suggested publication bias in the included literatures, and the sensitivity analysis indicated that the meta analysis results were relatively stable. Conclusion The adverse childhood exprience is positively associated with adolescent depression.Adolescent depression is strongly affected by neglected,and is least affected by abuse.

Objective: To explore the relationship between parent child relationship and rebelliousness of junior middle school students in boarding schools and to provide a scientific basis for preventing the occurrence of youth rebellion. Methods: A cluster sampling method was used to investigate parent child separation, family intimacy, and rebellion among 1 790 junior high school students in one boarding middle school in Lujiang County, Hefei City, Anhui Province in January 2020, and the influence of parent child relationship on students rebelliousness was analyzed by Chi square test and binary Logistic regression. Results: The detection rate of rebelliousness among participants was 21.45%(384/ 1 790 ). Junior middle school students who were in senior grade (second and third grades), reported higher household economic status and no communication with parents during the past month were more likely to have rebelliousness( OR=1.83, 1.89, 1.80, 1.77 , P <0.05); Junior middle school students with higher parental warmth and intimacy were less likely to have rebelliousness( OR=0.52, 0.71, P <0.05); Gender, length of boarding, maternal education, frequency of meeting parents during boarding, and childhood experience of separation with parents showed no statistical significance on rebelliousness( P >0.05). Conclusion The detection rate of rebellious psychology among junior high school students in boarding schools is high, and good parent child relationship is the protective factor of rebellious psychology. Parents should pay attention to contact with their boarding children and strengthen communication to reduce rebelliousness among them.

Objective: To determine the possible relations between hair cortisol concentration (HCC) as a biomarker of chronic stress and childhood overweight and obesity. Methods: Children from grade 1 to 3 from 2 primary schools in Bengbu were invited to participate in the study; and those who suffer from mental disorders, endocrine diseases and those who took hormone drugs were excluded. Parental questionnaire was implemented to collect information on physical activity, screen time, sleep duration, sugar-beverage consumption, as well as socio-economic status. Height and weight were examined. Eligible hair samples from 1 263 children (598 boys and 665 girls) were obtained, and the cortisol content was determined. Multivariate logistic regression model analysis was recruited to examine the association between HCC quartiles and overweight and obesity among boys and girls, respectively. Results: HCC in P₅₀ (P₂₅-P₇₅) among girls and boys was separately 11.86 (10.57-13.15) and 11.71 (10.54-13.09) µg/kg (Z=-0.886, P=0.376); HCC in P₅₀ (P₂₅-P₇₅) among non-overweight, overweight and obesity boys was separately 11.62 (10.45-12.82), 12.24 (10.88-13.55) and 12.30 (10.99-13.53) µg/kg (χ²=8.24, P=0.016); HCC in P₅₀ (P₂₅-P₇₅) among non-overweight, overweight and obesity girls was separately 11.35 (10.06-12.62), 12.07 (11.04-13.21) and 12.59 (11.12-13.63) µg/kg (χ²=36.16, P<0.001). After age, physical activity, screen time, sleep duration, sugared beverages and socio-economic status adjusted, compared with HCC in Q1 level, girls whose HCC in Q2, Q3 Q4 level had higher rates in overweight, with OR (95%CI) at 1.10 (1.04-3.32), 2.59 (1.51-4.45) and 3.16 (1.79-5.57), respectively. Girls with HCC in Q3 and Q4 level had higher rates in obesity, with OR (95%CI) at 2.22 (1.16-4.26) and 5.62 (3.04-10.41). Among boys, highest quartiles in HCC was risk factor for overweight, OR (95%CI) was 2.14 (1.18-3.90). Conclusion Hair cortisol had a significant relation with overweight and obesity in 6-9 years old childhood especially among girls.

Objective: To explore the mediating role of depression in the association between life events and Internet addiction, and to provide evidence for the intervention of Internet addiction. Methods: A total of 3 536 students randomly selected from 3 vocational colleges in Anhui Province completed the questionnaire survey, which included adolescents’ demographic characteristics, the Young Internet Addiction Inventory, the Adolescent Life Events Scale, and the Zung Self-Rating Depression Scale. Results: Of the 3 536 students surveyed, 427 were Internet addicts (12.08%), including 183 boys (14.89%) and 244 girls (10.58%). Negative life events were associated with depression and Internet addiction (r=-0.30，0.28, P<0.01); depression was mediated indirectly between negative life events and Internet addiction. There was statistical significance (a=0.30, b=0.13, P<0.01). Depression-mediated indirect effects accounted for 14.67% of the total effects. Conclusion Depression plays a mediating role in the relationship between negative life events and adolescents’ Internet addiction, suggesting that we can reduce the incidence of Internet addiction by reducing students’ depression through early psychological diagnosis and psychological quality training.
