BackgroundThis study aims to explore the effects of physical activity on adolescents' social skills and antisocial behavior, as well as gender and only child status differences among Chinese adolescents.MethodsWe used longitudinal data, collecting baseline data for 2021–2022 and follow-up in 2022–2023. A total of 3,206 students were enrolled, including 1,510 males (Age ± SE: 13.62 ± 1.69) and 1,696 females (Age ± SE: 14.09 ± 1.85), 1,339 only children (Age ± SE: 13.76 ± 1.95), and 1,867 non-only children (Age ± SE: 13.95 ± 1.66). The fixed effects model was used to identify the effects of different types of physical activity on adolescent social behavior and the heterogeneity analysis.Results(1) We found that skipping rope (β = 2.284, t = 5.76), walking (β = 3.495, t = 9.53), cycling (β = 1.271, t = 3.21), jogging (β = 2.614, t = 5.92), and badminton (β = 1.409, t = 2.96) had a positive impact on adolescents' social skills. Tag games (β = −1.615, t = −3.83), swimming (β = −2.862, t = −4.42), dancing (β = −1.11, t = −2.29), and skiing (β = −2.771, t = −3.27) had a negative impact on adolescents' social skills. Skipping rope (β = −1.596, t = −5.86), walking (β = −1.814, t = −7.44), cycling (β = −1.066, t = −4.07), and jogging (β = −1.617, t = −5.30) tended to reduce adolescents' antisocial behavior. Tag games (β = 1.685, t = 5.54), swimming (β = 0.947, t = 2.06), ice skating (β = 1.772, t = 2.71), and skiing (β = 1.468, t = 2.31) tended to increase adolescents' antisocial behavior. In addition, we found that these effects differ by gender and only child status. (2) Boys had significantly higher participation rates in activities. Only children had higher participation rates in skipping rope, baseball or softball, and volleyball, but non-only children had higher participation rates in walking, cycling, jogging, other aerobic exercises, and badminton. (3) Girls had higher social skills, but boys and only children had significantly higher rates of antisocial behavior.ConclusionOur results provide a novel understanding that can inform interventions and improvements in social behavior among Chinese adolescents. Stakeholders such as educators, policymakers, and health professionals can develop more tailored and effective strategies to promote positive social development among adolescents.

Abstract Purpose Risk behaviors are significantly impacting physical and psychological health among adolescents, resulting in a tremendous public health issue. The aim of this study is to examine the association of clustered risk behaviors with mental health and physical activity, and identify to what extent the clustering of various risk behaviors is associated with psychological health and physical activity in Chinese adolescents. Methods Students aged 16–18 years, male 16.2 ± 1.03, female 16.3 ± 1.56, were recruited from 30 high schools to complete an online questionnaire in fall semester 2017. A structured questionnaire, 2017 state and local youth risk behavior survey was revised, modified, and translated into Chinese. Five questions were designed to assess physical activity times of the last 7 days. Symptom checklist 90 (SCL-90) was used to investigate the mental health status of the participants. Statistical analyses were done employing chi-square tests, two step cluster analysis, logistic regression. Result Results illustrate that girls report a significantly higher mean of being bullied in school, electronically bullied, feeling sad or hopeless, and trying cigarette smoking. Two-step cluster analysis and regression analysis find that alcohol use, smoking and sedentary behavior have significant effect on adolescent health. Logic regression demonstrated that risk behaviors have significantly associated with mental health and physical activity in specific cluster. Conclusion This study finds that a specific behavior cluster has significant impact on mental health and physical activity among adolescents. Integrating risk behaviors cluster with factors can be employed to target high-risk adolescents who have poor physical and psychosocial health. The research suggest that more effective and feasible school intervention programs can be designed to promote adolescent health-related behavior in terms of those pathways.

Purpose: The aim of this study is to explore the relationship between screen-based sedentary behavior, physical activity and physical fitness among Chinese adolescents.Methods: This study randomly selected adolescents from 10 administrative districts in Shandong, China. The data gathering tools for demographic and other characteristics (gender, age, body mass index and socioeconomic status), PA (PAQ-A) and screen-based sedentary behavior (YRBSS) and physical fitness (NSPFH 2014) were utilized in this study. Statistical analysis was performed by T-test, chi-square test and multiple linear regression.Results: 10,002 adolescents (14.39 years ± 1.79) participated in the study. The results demonstrated that BMI and high TV viewing time had a significant negative correlation with physical fitness, but there was no association between the amount of time spent playing computer/video games and physical fitness among adolescents. High SES and physical activity in leisure time five or more times per week were significantly associated with most dimensions of physical fitness.Conclusions: the results suggest that we not only need to focus on adolescent risk behavior associated with low socioeconomic status and obesity, but also enforce physical activity and reduce sedentary television-watching behavior, which will be crucial pathways and strategies to improve the physical fitness of Chinese adolescents.

Purpose: To examine, within a social–ecological framework, associations between multifaceted individual and environmental factors and habitual physical activity (HPA) among older Chinese adults. Methods: Through a mix of qualitative and quantitative methods, a survey instrument assessing various factors underlying 3 social–ecological dimensions of intrapersonal, interpersonal, and community and environmental resources was developed. Using a cross-sectional design, older adults (n = 1580, aged 67 ± 7 years) recruited from 10 communities in Shandong province completed the social–ecological survey of HPA. Data were analyzed using Partial Least Squares Path Modeling. Results: Factors related to intrapersonal (medical knowledge, motivation, physical function, sport skills, socioeconomic status, and education), interpersonal (social support, social activity, and social norms), and community and physical environmental resources (safety, capacity, availability of and access to physical activity facilities) were found to be significantly associated with older adults' participation in HPA. Conclusion: The findings provide an initial validation of a social–ecological approach to the study of HPA in China, suggesting that strategies aimed at promoting physical activity in older adults should address multiple levels of factors that may contribute to the likelihood of older Chinese adults being physically active.

The decrease of quality of life and the frequent occurrence of risk behaviors among adolescents are one of the most urgent problems in our society, which identifies different health levels of adolescents in multiple dimensions such as physiological, psychological, emotional, and social. PURPOSE: The purpose of this study is to examine relationships between quality of life (QOL), socioeconomic status (SES), physical activity (PA), health-related risk behavior (HRB) among high school pupils and to explore how components of quality-of-life influence SES, PA and HRB in term of a socio-ecological model (SEM) METHODS: participants aged 16-18 years, male 16.2 ± 1.03, female 16.3 ± 1.56, were recruited from 30 high schools to complete QOL, risk behavior, physical activity times of the last 7 days. Canonical correlation analysis (CCA) explored modes of covariation between socioeconomic status, active lifestyle, and risk behavior variables. Logistic regression estimated relationships between PA, SES and HRB.RESULTS: the result showed that the adolescents with high screen time, low PA, smoking, and low SES showed a lower QOL score. Smokers under 10 years revealed the lowest QOL, and PA five days per week have the highest QOL. Logic regression demonstrated that QQL were associated with physical activity, the odds ratios (ORs) and 95% confidence intervals (CIs) for 1~2 times per week, 3~4 times per week and ≥5 times per week were 1.13 (0.66, 1.95), 0.51 (0.30, 0.87) and 0.54 (0.39, 0.76) respectively. QQL were associate with HRB, ORs and CIs for problematic screen time drinking of alcohol, smoking, bully behaviors, sedentary behavior are 1.32 (1.17,1.49), 1.35(1.22,1.45), 2.77(1.12,6.89), 2.71(0.93,0.68), 0.710(0.645,0.780), respectively. QQL were associate SES, ORs and CIs for parent education, income, Occupation are 1.00(0.77,1.29), 0.84(0.76,0.92), 1.05(0.93,1.19), respectively. Alcohol use, smoking and sedentary behavior have significant effect on adolescent Quality of Life CONCLUSIONS: QOL was negatively associated with low SES, unphysical activity, smoking, screen time and sedentary behavior. More than PA five or more days for boys and three or four days per week for girls could decrease negative effects of risk behaviors and improve QOL. [ABSTRACT FROM AUTHOR]

Background: Many randomized controlled trials have investigated the effects of exercise on the rehabilitation of patients with breast cancer. However, the exercise forms used in most previous studies were monotonous. Therefore, we designed a protocol to estimate the effects of combined exercise intervention using Internet and social media software on the rehabilitation of postoperative patients with BC.Methods/design: This study protocol is a randomized control trial with an intervention time of 12 weeks. After completing baseline questionnaire and physical fitness tests, the participants are randomized to the study group or the control group. Procedure contents of exercise intervention in the study group include: via phone step-recording app, ask the individuals to complete the target number of steps within a specified period of exercise, four times per week; face-to-face remote video guidance of individuals on muscle training, three times per week; common knowledge of physical exercise BC rehabilitation will be pushed regularly by social media apps every day. The control group will receive normal treatment and rehabilitation according to daily specifications of the hospital. The primary outcome will be the quality of life. The secondary outcomes are physical fitness and social cognitive indicators.Discussion: This study is a clinical trial to estimate the effects of combined exercise intervention based on the Internet and social media software for postoperative patients with breast cancer (BC). If expected results are achieved in this study, measures and methods of BC rehabilitation will be enriched.Trial Registration: Chinese Clinical Trial Register, ChiCTR-IPR-17012368 .
