Background: Livable environment and ways, as the necessary conditions for the elderly to enjoy their old age, have a significant impact on their mental health and happiness. It's crucial to understand how living arrangements affect depressive symptoms in China. Studies on how various leisure activities modify this association are yet limited. Methods: This study relies on panel data derived from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), collected during waves spanning 2008/2009, 2011/2012, 2014, and 2018. The primary objective is to examine the relationship between living arrangements, leisure activities, and depressive symptoms of elderly individuals. Linear mixed -effects models were used to analyze the data. Results: A total of 26,342 observations aged 65 and over were included in this paper. Older adults living alone (beta = 0.66, 95 % CI: 0.55, 0.76) or living in institutions (beta = 0.69, 95 % CI: 0.40, 0.98) had more depressive symptoms than those living with family. Leisure activities were negatively associated with depressive symptoms (beta = -0.16, 95 % CI: -0.18, -0.15). Moreover, there was significant interactions between living arrangements and leisure activities. No matter which kind of living arrangements, participating in physical, productive or social activity was associated with a lower risk of depressive symptoms. Limitations: Study design might introduce bias, and it cannot establish causality between the tested variables. Conclusions: Older adults living alone or in institutions have more possibility to develop depressive symptoms than those living with family, and such a relationship among Chinese older adults can be moderated by participating in leisure activities.

This study aims to investigate the associations of caring for grandchildren and/or great-grandparents with depressive symptoms, as well as life satisfaction in Chinese grandparents, and analyze the moderating roles of urban-rural residence and social participation. A nationally representative sample of 2973 grandparents in families with great-grandparents and grandchildren were selected from the 2018 China Health and Retirement Longitudinal Study (CHARLS). The Center for Epidemiologic Studies Depression (CESD-10) and the single-item were used to measure depressive symptoms and life satisfaction. Social participation included participation in social and intellectual activities. The binary logistic regression model was employed to explore the relationship between caring and depressive symptoms, as well as life satisfaction in the whole participants, different urban-rural residence, and social participation groups, respectively. Caring was associated with depressive symptoms and life satisfaction (p < 0.05). A significant interaction existed between caring and urban-rural residence for depressive symptoms (interaction p = 0.029) and life satisfaction (interaction p = 0.027). Significant interactions were also found among caring, urban-rural residence, and social activities with depressive symptoms (interaction p = 0.025). In urban, caring for both was negatively related to depressive symptoms for the non-social activists, while in rural, caring for great-grandparents was positively associated with depressive symptoms for social activists (p < 0.05). Any new policy design related to preventing and reducing the possibility of mental disorders in Chinese grandparents should be tailored to heterogeneous subgroups who live in different rural-urban and social activities participation.

Background: Despite a great deal of existing research on nurses’ job stress and intention to stay, it is still unclear how the association between Chinese nurses’ job stress and intention to stay is affected by presenteeism and family functioning. Aims: This study aimed to investigate the correlations of Chinese nurses’ job stress, presenteeism, and family functioning with their intention to stay and clarify the mediating effect of presenteeism and the moderating effect of family functioning on the association between their job stress and intention to stay. Method: A cross-sectional study of 1,008 nurses was performed in a major general hospital in Qiqihar City, Heilongjiang Province, China. The participants were invited to engage in a questionnaire survey regarding job stress, presenteeism, family functioning, and intention to stay. A moderated mediation analysis was conducted through multiple linear regression analysis and the PROCESS macro. Results: Job stress and presenteeism were negatively correlated with intention to stay, whereas family functioning was positively correlated with intention to stay. The effect of job stress on intention to stay was partially mediated by presenteeism (Effect = −0.147, 95% CI = [−0.305, −0.003]). In addition, family functioning moderated the direct effect of job stress on intention to stay (Index = −0.134, 95% CI = [−0.274, −0.001]). Conclusions: Presenteeism and family functioning were found to play mediating and moderating roles, respectively, in the relationship between job stress and intention to stay. Relevant interventions or family-friendly programs should be developed to enhance nurses’ intention to stay.

Background Since few studies have incorporated factors like stressors, coping styles, and academic burnout into the same model to analyze their impacts on depressive symptoms, this research attempts to establish an optimal structural model to explore the direct and indirect effects of these factors on depressive symptoms. Methods A total of 266 postgraduates completed questionnaires regarding coping styles, academic burnout, stressors, and depressive symptoms. The path analysis was applied for investigating the roles of coping styles and academic burnout in mediating the relationship between stressors and depressive symptoms. Results The total and direct effects of stressors on depressive symptoms were 0.53 and 0.31, respectively. The proportion of the direct effect of stressors on depressive symptoms to its total effect amounted to 58.50%. The indirect effects of academic burnout, positive coping style, and negative coping style on the association between stressors and depressive symptoms were 0.11, 0.04, and 0.03, taking up 20.75%, 7.55%, and 5.66% of the total effect, respectively. The serial indirect effect of positive coping style and academic burnout was 0.02, accounting for 3.77% of the total effect, while that of negative coping style and academic burnout was 0.02, taking up 3.77% of the total effect. Conclusions Coping styles and academic burnout chain jointly mediate the relationship between stressors and depressive symptoms among postgraduates. Thus, encouraging postgraduates to tackle stress positively may reduce the likelihood of the development of academic burnout and further reduce depressive symptoms.

Objective:To analyze the acceptance of self-rescue health education for public emergencies among Chinese mi-grants and its influencing factors,so as to provide reference for improving the situation of emergency literacy of Chinese migrants.Methods:Data of the 2018 China migrants dynamic survey were used for analysis,and the random forest model was used to rank the importance of variables and reduce their dimensions.Variables with the minimum error rate of out-of-bag estimation was incor-porated into the logistic regression to analyze the direction and relative risk of the independent.Results:The acceptance rate of self-rescue health education in public emergencies of Chinese migrants was 32.2%,and the error rate of out-of-bag estimation was lowest when the number of variables was 8.The top eight variables of importance were education level,health records,inflow re-gion,average monthly household income,range of flow,household registration,age and reason of flow.The regression results showed that the middle school(OR=1.361),high school and junior college(OR=1.651),and college and above(OR=1.709)compared to elementary school and below,and the lower-middle-income(OR=1.204),middle-income(OR=1.380),middle-upper-income(OR=1.428),and upper-income(OR=1.404)compared to the low-income group as well as Chinese migrants within the province across municipalities(OR=1.078)and within municipalities across counties(OR=1.049)compared to across provinces were more likely to receive self-help health education on public emergencies.Chinese migrants aged 60 years and above(OR=0.898),agricultural household registration(OR=0.880),health record unregistered(OR=0.630),the reason of mobility was family moving(OR=0.649)and marriage(OR=0.702),and northeast region(OR=0.722)were less likely to receive self-rescue health education in public emergencies.Conclusion:The acceptance rate of self-help education on public emergencies a-mong Chinese migrants is low.The overall level of acceptance of self-help health education increases with the level of education and average monthly household income,and there are population and regional differences.It is necessary to increase emergency educa-tion and publicity for key populations,strengthen the allocation of resources,and promote the equalization of basic public health services.

OBJECTIVE:This study aims to verify the moderating roles of lifestyle factors and age between body mass index (BMI), BMI trajectory and depressive symptoms of Chinese adults through a prospective design. METHODS:The participants who are 18 years old and above from the China Family Panel Studies (CFPS) were included in the 2016 baseline and 2018 follow-up research. BMI was calculated according to self-report weight (kilogram) and height (centimeter). Depressive symptoms were evaluated via the Center for Epidemiologic Studies Depression (CESD-20) scale. Inverse probability-of-censoring weighted estimation (IPCW) was used to check whether selection bias existed. Modified Poisson regression was performed to calculate prevalence and risk ratios as well as 95% confidence intervals. RESULTS:After adjustment, it was found that the positive associations of persistent underweight (RR = 1.154, P < 0.001) and normal weight → underweight (RR = 1.143, P < 0.001) with 2018 depressive symptoms were significant among middle-aged people, while the negative association of persistent overweight/obesity (RR = 0.972, P < 0.001) was significant in young adults. Notably, smoking moderated the relationship between baseline BMI and subsequent depressive symptoms (interaction P = 0.028). Also, exercise regularly and exercise duration weekly moderated the relationships of baseline BMI (interaction P = 0.004 and 0.015) and trajectories of BMI (interaction P = 0.008 and 0.011) with depressive symptoms among Chinese adults, respectively. CONCLUSION:Weight management strategies for underweight and normal weight → underweight adults should pay attention to the role of exercise in maintaining normal weight and improving depressive symptoms.

Nurses’ mental health is related to the quality of medical care and the outcome of treatment, and has become an important issue in nursing management. However, the role of burnout in the relationship between job satisfaction and psychological distress have not been evaluated. This study aimed to examine the prevalence of psychological distress among Chinese nurses and explore the associations of job satisfaction and burnout with psychological distress. A cross-sectional survey of 866 nurses was conducted in Qiqihar City, Heilongjiang Province of China. Job satisfaction, burnout, and psychological distress were assessed via the single-item, the Maslach Burnout Inventory-Human Services Survey, and the 12-item General Health Questionnaire respectively, followed by a mediation analysis through the multiple regression analysis and a PROCESS macro method. The prevalence of psychological distress was 35.2% among the participants. After controlling the potential confounding factors, job satisfaction and burnout were found to be still associated with psychological distress ( P < 0.001). Furthermore, psychological distress was negatively correlated with both job satisfaction ( r = -0.312) and personal accomplishment ( r = -0.422) but positively correlated with both emotional exhaustion ( r = 0.491) and depersonalization ( r = 0.449). Burnout may mediate the association between job satisfaction and psychological distress ( B = 0.139, β = 0.440, P < 0.001 for emotional exhaustion; B = 0.226, β = 0.382, P < 0.001 for depersonalization; and B = -0.105, β = -0.368, P < 0.001 for personal accomplishment). The mental health status of Chinese nurses remains to be improved. Low job satisfaction and burnout could increase the risk of psychological distress among Chinese nurses. Moreover, job satisfaction may partially affect psychological distress among Chinese nurses through emotional exhaustion, personal accomplishment, and depersonalization.

(1) Background: This study aimed to explore the factors associated with the subjective well-being (SWB) of Chinese adolescents from a more comprehensive perspective and to analyze the importance of its influencing factors. (2) Methods: Obtained from the China Family Panel Studies (CFPS) 2018, the research data involved 2316 adolescents aged 10–15. By using the Chi-square test, t-test and binary logistic regression, we investigated the associations of individual-, family- and community-level factors with SWB in Chinese adolescents. To explore the rank of the influencing factors of SWB, the random forest model was set up. (3) Results: In individual-level factors, girls, who were adolescents with higher academic performance and school satisfaction, with the habit of midday napping and reading books, and with higher self-esteem, had a higher SWB. In family-level factors, mothers living at home resulted in a higher SWB, while quarrelling with their parents led to low SWB. In community-level factors, adolescents with better social relationships, social trust and who were better at telling their troubles to others had a higher SWB. Based on the random forest model, the importance degree was ranked, and the top five were decided, including self-esteem (89.949), social relations (43.457), academic performance (31.971), school satisfaction (27.651) and quarrelling with parents (19.026). (4) Conclusions: Self-esteem, social relations, academic performance, school satisfaction and quarrelling with parents are all important variables that are related to the SWB of Chinese adolescents.

Background: Few studies have explored the internal pathway of the association between sleep quality and subjective well-being among perimenopausal women. Methods: A survey was performed of 1063 perimenopausal women aged 40 to 60 years who participated in a regular health examination conducted at the First Hospital of Jilin University, China. Participants were asked to complete a study questionnaire. The Pittsburgh Sleep Quality Index, Zung Self-rating Anxiety Scale, Perceived Social Support Scale and Subjective Well-being Scale for Chinese Citizens were used to assess sleep quality, anxiety symptoms, social support and subjective well-being, respectively. The data were analyzed using t-tests, analysis of variance, Pearson correlation analysis, multiple linear regression analysis and the PROCESS macro. Results: The mean total subjective well-being score was 90.14 +/- 12.80. The correlation analyzes showed that sleep quality (r =-0.341, P < 0.001) and anxiety symptoms (r =-0.490, P < 0.001) were negatively correlated with subjective well-being. Social support was positively correlated with subjective well-being (r = 0.480, P < 0.001). The effect of sleep quality on subjective well-being was partially mediated by anxiety symptoms (Effect =-0.462, 95% CI = [-0.577, -0.363]). In addition, social support moderated the association between anxiety symptoms and subjective well-being (Index =-0.006, 95% CI = [-0.012,-0.001]). Limitations: This was a cross-sectional study. Conclusions: The effect of sleep quality on subjective well-being was partially mediated by anxiety symptoms, and social support moderated the association between anxiety symptoms and subjective well-being among perimenopausal women.

This study aims to explore the associations between personality traits and depressive symptoms among Chinese adults and analyse the gender and age differences in the associations. A national representative sample of 28,628 adults aged 18 and above were selected from the 2018 China Family Panel Studies (CFPS) data. The short version of the Big Five Inventory (CBF-PI-15) and the Center for Epidemiologic Studies Depression (CES-D 8) were used to measure personality traits and depressive symptoms respectively. Binary logistic regression models were employed to analyse the associations between personality traits and depressive symptoms in the whole participants, different age groups and genders respectively. After adjustment, higher levels of conscientiousness, extraversion and agreeableness were related to lower level of depressive symptoms, while higher levels of openness and neuroticism were related to higher level of depressive symptoms (p < 0.05). A significant interaction between gender and conscientiousness on depressive symptoms was found (interaction p = 0.005), and the association between conscientiousness and depressive symptoms was stronger in males than females (p < 0.001). Significant interactions between age and conscientiousness (interaction p = 0.007), agreeableness (interaction p = 0.001) on depressive symptoms were found respectively. Moreover, the associations of conscientiousness and agreeableness with depressive symptoms were strongest among old group, followed by middle-aged group, and then young group (p < 0.05). In conclusion, conscientiousness, extraversion and agreeableness had negative associations with depressive symptoms, while openness and neuroticism had positive associations with depressive symptoms. The negative association between conscientiousness and depressive symptoms was stronger among males than females, and the negative associations of conscientiousness and agreeableness with depressive symptoms were strongest among old group, followed by middle-aged group, and then young group.

Objectives: This study aims to explore the associations of personality traits and extra-family social relationship with depressive symptoms among Chinese adults.Methods: A nationally representative sample of 29,810 adults aged 16 and above were selected from 2018 CFPS. Personality and depressive symptoms were measured using CBF-PI-15 and the CES-D8 scale. Extra-family social relationship was assessed through the self-rated evaluation. The multiple regression analysis and the PROCESS macro were used for the mediation analysis.Results: Extraversion (OR = 0.807, 95% CI = 0.773, 0.842), agreeableness (OR = 0.795, 95% CI = 0.756, 0.835) and extra-family social relationship (OR = 0.927, 95% CI = 0.913, 0.941) had negative associations with depressive symptoms. Extra-family social relationship could mediate between extraversion and depressive symptoms (Indirect effect = -0.049,95% CI = -0.060, -0.039) as well as agreeableness (Indirect effect = -0.056, 95% CI = -0.068, -0.046) and depressive symptoms. Comparing to females, the indirect effect accounts for a higher proportion of total effect in males.Conclusion: Extra-family social relationship might mediate the association between extraversion and depressive symptoms as well as agreeableness and depressive symptoms.

Objectives Based on a prospective design, this study aimed to investigate the relationships of leisure activities with physical and cognitive functions among Chinese older adults. Methods The respondents aged 65 years or more were selected from the 2014-2018 of the Chinese Longitudinal Healthy Longevity Survey. Physical function measurement indicators were reflected by activities of daily living (ADL), instrumental activities of daily living (IADL), and physical performance (PP), while cognitive function was assessed by Mini-Mental State Examination. Fine-Gray competing risk regression models were used to analyze the data. Results Using the figures for 2014 as a baseline for the study, we included 6047, 6216, 5951, and 5916 respondents in the ADL, IADL, PP, and cognitive function analyses, respectively. The prospective results showed that keeping domestic animals or pets was related to a lower risk of ADL disability of respondents after adjustment (SHR: 0.619, 95% CI: 0.486, 0.788). Similarly, taking part in social activities (SHR: 0.781, 95%CI: 0.658, 0.929) and reading books or newspapers (SHR: 0.793, 95% CI: 0.656, 0.958) were associated with a lower risk of IADL disability. Playing cards or mahjong was correlated with a lower risk of cognitive impairment (SHR: 0.669, 95% CI: 0.507, 0.882), while keeping domestic animals or pets was related to a higher risk of cognitive impairment (SHR: 1.279, 95% CI: 1.047, 1.562). Conclusion Participation in leisure activities moderately may decrease the risk of a decline in physical and cognitive functions among Chinese older adults.

Background The impact of perceived life stress on subjective well-being has been well-established; while few studies have explored the mediating and moderating mechanisms of the association between perceived life stress and subjective well-being among perimenopausal women. This study is aimed at exploring the mediating effect of depressive symptoms and the role of interests/hobbies as a moderator in the association between perceived life stress and subjective well-being among perimenopausal women. Methods The participants were 1,104 perimenopausal women at the age of 40 to 60, who were asked to complete a paper-based questionnaire. A single item was used to measure self-perceived life stress and interests/hobbies. The Zung Self-rating Depression Scale (SDS) and Subjective Well-being Scale for Chinese Citizens (SWBS-CC) were applied to assess both depressive symptoms and subjective well-being. Multiple linear regression analysis and the PROCESS macro were adopted to analyse not only the mediating effect of depressive symptoms but also the moderating role of interests/hobbies. Results Perceived life stress was negatively associated with subjective well-being (B = − 1.424, β = − 0.101, P < 0.001). The impact of perceived life stress on subjective well-being was partially mediated by depressive symptoms (mediation effect = −0.760, 95% confidence intervals (CI) [−1.129, −0.415]). In addition, the interaction term between depressive symptoms and interests/hobbies was significantly related to subjective well-being (β = − 0.060, P < 0.05), indicating moderating effect. Moderated mediation had a significant index (Index = −0.220, SE = 0.099, 95% CI [−0.460, −0.060]). Conclusions Perceived life stress was negatively related to subjective well-being. The impact of perceived life stress on subjective well-being was mediated by depressive symptoms. Besides, interests/hobbies moderated the indirect effect of depressive symptoms on the relationship between perceived life stress and subjective well-being.

Background: This study aimed at exploring the associations of parent-adolescent relationship and self-esteem with emotional and behavioral problems (EBPs) among Chinese adolescents using a large-scale nationally questionnaire survey data from China. Methods: Obtained from China Family Panel Studies (CFPS) 2018, the research data involved 2400 adolescents aged 10-15. Multiple linear regression analysis and the PROCESS macro were used for examining the mediating effect of self-esteem on the associations of parent-adolescent relationship with EBPs. Results: After controlling the potential confounding factors, parent-adolescent relationship and self-esteem were significantly associated with EBPs (P < 0.01). Correlation analysis results showed that parent-adolescent relationship (r =-0.116, P < 0.01) and self-esteem (r =-0.209, P < 0.01) were negatively correlated with EBPs. Self-esteem partially mediated the associations of parent-adolescent relationship with EBPs among Chinese adolescents. Limitations: The cross-sectional design limited the ability to make causal inferences. Conclusions: Positive parent-adolescent relationship and high self-esteem contributed to fewer EBPs of adolescents. Parent-adolescent relationship predicted EBPs partially mediated by self-esteem. Establishing positive parent-adolescent relationship and improving individual self-esteem may thus be promising targets for intervention in adolescents with EBPs.

Background Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality. Methods A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data. Results The prevalence of poor sleep quality was 26.7%. Negative life events ( B = 0.038, P < 0.001) and negative coping style ( B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality ( B = −0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles. Conclusions Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

Aims and objectives The present study was aimed at describing the status of job burnout and exploring the mediating roles of psychological capital and professional identity on the association between organisational justice and job burnout. Background With the shortage of nurses all over the world, nurses' job burnout has become the focus of studies in recent years. However, limited published research has examined the mediating roles of psychological capital and professional identity on the association between organisational justice and job burnout within hospital contexts in China. Design A cross-sectional design. Methods A total of 1,009 nurses were enrolled from a major general hospital located in Qiqihar City in the northeast of China from March-July 2018, and asked to complete questionnaires regarding organisational justice, psychological capital, professional identity and job burnout. The STROBE checklist was adhered to in this study. Results It was observed that the overall proportion of nurses with job burnout was 58.8%. All the correlations among organisational justice, psychological capital, professional identity and job burnout were statistically significant, with coefficients ranging between -0.487-0.863. Psychological capital and professional identity had indirect effects equal to -0.072 and -0.142, respectively, on the association between organisational justice and job burnout, taking up 13.7% and 26.9% of the total effect, respectively. The serial indirect effect of psychological capital and professional identity was -0.129, accounting for 24.5% of the total effect. Conclusions This study showed the necessity of addressing the status of job burnout among Chinese nurses. Psychological capital and professional identity may mediate the linkage between organisational justice and job burnout independently and accumulatively. Relevance to clinical practice Nursing managers should strengthen organisational justice and improve the psychological capital and professional identity of nurses through effective strategies to prevent the job burnout of nurses.
