The Influence of Adolescents' Cognitive Stress on Their Suicidal Intention: Focusing on Mediating Effect of Physical Activity, Problem Drinking, Cognitive Depression

BACKGROUND Physical inactivity is a risk factor for chronic noncommunicable diseases. Insufficient physical activity has become an important public health problem worldwide. As mobile apps have rapidly developed, physical activity apps have the potential to improve the level of physical activity among populations. OBJECTIVE This study aimed to evaluate the effect of physical activity apps on levels of physical activity among college students. METHODS A Web-based questionnaire was used to survey college students in Beijing from December 27, 2017, to January 5, 2018. According to a previous survey, 43% of college students using physical activity apps and 36% of those who never used such apps achieved the physical activity recommendations. In this study, the sample size was calculated to be 500. The questionnaire consisted of 5 parts: the use of physical activity apps, sports habits, social support, self-efficacy, and social demographic information. Structural equation modeling was used to test the relationships between the use of physical activity apps, self-efficacy, social support, and level of physical activity. RESULTS Of the 1245 participants, 384 college students (30.8%) used physical activity apps (in the past month). Of these 384 students, 191 (49.7%) gained new friends via the app. College students who were using physical activity apps had a higher level of physical activity and higher scores for social support and self-efficacy (<italic>P</italic><.001) than those who did not use such apps. The use of physical activity apps significantly affected the mediating effect of physical activity level through social support (beta=.126; <italic>P</italic><.001) and self-efficacy (beta=.294; <italic>P</italic><.001). Gender played an important role in app use, self-efficacy, and physical activity in the mediation model: male users spent more time on physical activity and had higher self-efficacy scores (<italic>P</italic><.001). CONCLUSIONS This study focused on college students in Beijing and found that the use of physical activity apps is associated with higher physical activity levels among these students. This effect is mainly through the mediation effect of social support and self-efficacy, rather than the direct effect of physical activity apps. The use of physical activity apps is associated with a higher social support level and higher self-efficacy score. Furthermore, a high social support level and high self-efficacy score are associated with higher physical activity levels.

Abstract Background Social disadvantage and unhealthy lifestyles may induce molecular changes associated with aging and age-related diseases. For instance, previous studies reported socioeconomic difference in DNA methylation, which in turn led to aberrant gene expression and genome instability. Socioeconomic status (SES) alone, however, does not completely explain this difference, and further studies are needed to unveil what factors contribute to it. Methods We conducted a cross-sectional study on 349 Italian women, aged 25-64 years, to assess SES differences in LINE-1 methylation level - a surrogate marker of global DNA methylation - and to examine the mediating effect of lifestyles (i.e. diet, smoking habits, physical activity, and weight status). Educational level was used as SES indicator. The adherence to Mediterranean diet (MD) was assessed by the Mediterranean Diet Score (MDS). Leukocyte LINE-1 methylation was assessed by pyrosequencing. Mediation analysis was conducted using the PROCESS macro for the SPSS software. Results We first observed that women with high educational level were more likely to be normal weight (p < 0.001) and to adhere to MD (p = 0.018), and less likely to perform physical activity (p = 0.012) than their less educated counterpart. Moreover, age-adjusted linear regression demonstrated that LINE-1 methylation level increased with increasing educational level (β = 0.016; SE = 0.003; p < 0.001). In line, mediation analysis demonstrated an indirect effect of high educational level on LINE-1 methylation through the adherence to MD (β = 0.003; 95%CI=0.001-0.006). Specifically, the mediator could account for 9.5% of the total effect. None of the other lifestyles, instead, exhibited a significant mediating effect. Conclusions To our knowledge, this is the first study demonstrating the mediation of diet in the relationship between SES and DNA methylation. Thus, our findings add even more value to the promotion of healthy dietary habits among social disadvantaged people. Key messages Social disadvantage is associated with epigenetic changes related to aging and age-related diseases. Adherence to the Mediterranean diet might mediate the association between socioeconomic status and DNA methylation.

Proposed Model

Prior studies have shown that physical activity (PA) is strongly associated with lifelong health and well-being. Thus, analyses of relationships among individual differences, PA, education, and health may provide important insights into the sustainability of PA-related personal development efforts. In this longitudinal study, we tested a proposed model in a data set of 12,686 participants from the National Longitudinal Survey of Youth 1979 (NLSY 79). We used hierarchical regressions and bootstrapping to test hypotheses concerning the main effect of personal control on lifetime health, the mediating effect of PA, and the moderating effect of educational achievement. We found that individuals’ self-reported PA was positively related to their health status. Additionally, there was a positive mediating effect of self-reported PA on the relationship between personal control and health when the individual’s educational level was high, and there was a negative mediating effect of self-reported PA when an individual’s educational level was low. Based on these results, we provide relevant government policy suggestions for increasing fitness participation, constructing sports facilities, and encouraging educational institutions to include health education in their efforts.

The objective of the present study was to examine the associations between residents’ physical activity, health values, and well-being during isolation. On the basis of the physical activity rating scale, health values scale, subjective well-being scale, and the satisfaction with life scale, we collected 505 valid questionnaires online from 31 provinces, municipalities, and autonomous regions in China. A series of multiple linear regression models were established to study the relationship between variables, and the bootstrap confidence interval was selected to test the mediating effect. The results showed that during the period of isolation, physical activity directly (b = 0.463, p < 0.001) or indirectly (b = 0.358, p < 0.001) had a positive impact on residents’ well-being through the mediating effect of health values. There was a positive correlation between physical activity and health values (b = 0.710, p < 0.001), while health values had a direct positive association on well-being (b = 0.504, p < 0.001). In addition, a moderate amount of physical activity was found to be more associated with the well-being of residents during home isolation compared to small and large amounts of physical activity. This study shows the importance of residents’ physical activities in home isolation. Moderate exercise at home and regular physical activity are beneficial to our physical and mental health, especially in terms of improving overall well-being.

The research aim was to investigate associations between objectively-assessed built environment attributes and metabolic risk in adolescents of Pacific Islands ethnicity, and to consider the possible mediating effect of physical activity and sedentary time. Youth (n = 204) undertook a suite of physical assessments including body composition, blood sampling, and blood pressure measurements, and seven day accelerometry. Objective measures of the neighbourhood built environment were generated around individual addresses. Logistic regression and linear modelling were used to assess associations between environment measures and metabolic health, accounting for physical activity behaviours. Higher pedestrian connectivity was associated with an increase in the chance of having any International Diabetes Federation metabolic risk factors for males only. Pedestrian connectivity was related to fat free mass in males in unadjusted analyses only. This study provides evidence for the importance of pedestrian network connectivity for health in adolescent males. Future research is required to expand the limited evidence in neighbourhood environments and adolescent metabolic health.

The issue of work-related mental health needs to be addressed at the school level. The aim of this study was to explore the associations between academic stress (AS) of adolescent boys and girls and their physical activity (PA) during recesses and after school and to propose measures to promote the adoption of lifelong healthy working habits. Adolescents from 16 schools in the Czech Republic and 6 schools in Poland participated in the study (187 boys and 339 girls). Monitoring of PA and cognitive stress was conducted during one school day. We used ActiTrainer accelerometers to monitor PA and physical inactivity. Data on time of PA and self-reported AS in school lessons were collected using recording sheets. We split the participants into two groups: those without a self-reported stressor and those who indicated one or more stressors. Differences in overall PA during recesses, as well as after-school PA, between boys with and without AS were not statistically significant for any PA characteristics. We observed similar results for girls. Repeated measures ANOVA confirmed that differences in PA (steps/hour) during recesses following particular lessons between participants with and without AS were not statistically significant in boys or girls (F(4,1612) = 1.83, p=0.121 , ηp2=0.005). It is noteworthy that girls with AS were statistically significantly more likely to meet the 6000 steps after school time recommendation (39%) than girls without AS (18%; p<0.001). The study did not confirm the assumption that adolescents reporting AS have less PA during recesses or even after school than adolescents without AS. However, the overall low PA of adolescents during recesses and after school highlights the need to compensate for AS by adequate PA. This is especially true for adolescents with recurrent AS in several consecutive lessons.
