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.

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 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 understand the relationship between eye strain and eye health behavior in college students learning at home during the period of COVID-19 epidemic, and to provide a scientific reference for improving the hygiene of using eyes among the college students. Methods: A cross sectional study and stratified cluster sampling was used to select 2 671 college students from 8 colleges in Anhui Province during the March 1st to July 1st in 2020, and an online questionnaire was survey included general information,eye strain,and daily eye health behavior. Results: The prevalence of eye strain in college students was 69.64%. Multivariable Logistic regression analysis showed that eye strain was correlated with gender, myopia, siesta habit, staying up until 2:00 am, and the use of eye liquid, with OR values(95% CI ) were 0.64(0.53-0.76), 1.77(1.42- 2.20 ),0.71(0.59-0.86), 1.39(1.17-1.65), and 2.18(1.71-2.79), respectively. There was no correlation among daily outdoor activity time, daytime reading time and the occurrence of eye strain( P >0.05). Conclusion During the period of COVID-19 epidemic, eye strain among college students is common. The daily eye health behavior is related to the occurrence of eye strain. Under the special learning context, eye care measures should be encouraged specifically.

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.

Objective: To explore the relationship between childhood sexual abuse (CSA) experience and sexual behavior among female nursing students and to provide a scientific reference for intervening sexual behavior for female nursing students. Methods: A cross-sectional study was conducted among 2 549 female students majoring nursing from four medical schools (one is a medical college and the other is medical junior college) by self-administered questionnaire. A questionnaire survey regarding demographic information, childhood sexual abuse, sexual behavior was conducted and multi-factor Logistic regression method was used to analyze the effect of childhood sexual abuse in different stages made on their sexual behavior. Results: Among 2 549 female nursing students, 143(5.6%) reported having had sexual intercourse, 141 reported having had sexual intercourse with the opposite sex, 6 reported having had sexual intercourse with the same sex, and 4 reported having sexual intercourse with both sexes. The report rate of sexual behavior of nursing students in undergraduate colleges (6.8%) was lower than that of junior college (3.9%), the second-grade nursing students reported the highest rate of sexual behavior (7.8%), the lowest in first grade (4.0%). Nursing students in good relationship with parents reported lowest rate of sexual behavior(P<0.05). Compared to those who had not experienced CSA, students who had experienced contacting or no-contacting CSA reported a higher percentage engaged in sexual intercourse(P<0.05). CSA in all types and different stages in childhood associated with higher risk of sexual intercourse among nursing students(P<0.05). Conclusion Childhood sexual abuse shows significant impacts on sexual behaviors during young adulthood, which warrants further attention to promote physical and mental health of college students.

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 investigate the correlation between childhood maltreatment and quality of life (QOL) in nursing girls in Anhui Province, so as to provide reference for improving QOL of nursing girls. Methods: The stratified cluster sampling method was used to select students of grade 1 to 3 in nursing major from 2 colleges and 2 specialized colleges by self-administered questionnaire in Anhui province. The questionnaire was conducted to analyze the relationship between childhood abuse and neglect and QOL of female nursing students. Multiple linear regression model was used to assess the associations between childhood maltreatment and QOL. Results: Among 2 549 female nursing students, the mean scores of 4 dimensions of QOL were physical (12.85±2.01), psychological (13.86±2.40), social relationship (12.83±2.84) and environment (13.37±2.21). The scores of QOL among college students were higher than specialized college students, high grade students were higher, and those who have a good relationship with their parents were higher(P<0.01). The prevalence rates of childhood physical abuse, emotional abuse, sexual abuse, physical neglect, and emotional neglect were 4.9%, 10.6%, 7.3%, 6.7% and 4.1%, respectively. The scores of QOL were lower among female nursing students with childhood maltreatment than those without childhood maltreatment(P<0.01). The results of multiple linear regression analysis showed that the number of childhood abuse and neglect were negatively correlated with physical, psychological and environmental dimension of QOL, and the number of childhood maltreatment were significantly dose-responsive to quality of life(P<0.05). Conclusion The female nursing students are still greatly neglected, and the experience of childhood maltreatment is negatively related to the quality of life among female nursing students.
