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: Breast cancer patients in treatment suffer from long-term side effects that seriously influence their physical and mental health. The aim of this study was to examine effectiveness of a 12-week multicomponent exercise (ME) with remote guidance intervention on health-related outcomes after one year among breast cancer patients. Methods: In phases I–III, 60 patients (51.2 ± 7.9 years) with breast cancer (BC) who completed chemotherapy/postoperative radiotherapy within the previous four months to two years were randomly assigned to (1) multicomponent exercise with remote guidance (ME) and (2) usual care (UC). Eligible participants were approached to assess cancer-related quality of life (QOL), muscle strength, cardiorespiratory endurance, and physical activity (PA) barriers after one year. Results: The results demonstrated that, after one year, the ME group reported higher vitality-related QOL (5.776, 95% confidence interval [CI] 0.987, 10.565, effect size [ES] = 0.360), mental health-related QOL (9.938, 95% CI 4.146, 15.729, ES = 0.512), leg strength and endurance (2.880, CI 1.337, 4.423, ES = 0.557), and strength and endurance of upper extremities (2.745, 95% CI 1.076, 4.415, ES = 0.491) and lower physical activity (PA) hindrance (5.120, 95% CI 1.976, 8.264, ES = 0.486) than the UC group. Conclusions: The ME group observed significant differences from the UC group in QOL, muscle strength, cardiopulmonary endurance, and PA participation. These findings suggested that the multicomponent exercise intervention with remote guidance produced long-term health benefits for breast cancer patients.
