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.
Background: The aim of this study is to assess the clinical effectiveness and safety of hyaluronic acid gel for the prevention of postoperative intrauterine adhesions (IUAs). Methods: PubMed, Cochrane Library, Embase and ClinicalTrials.gov databases were searched for randomized controlled trials. Results: Six RCTs with a total of 564 patients met the inclusion criteria. The meta-analysis showed that, compared to no other treatment method, hyaluronic acid gel significantly reduced the rate of any IUA (risk ratio [RR] 0.68; 95% CI 0.53–0.86; p = 0.03; I2 = 64%) and adhesion score (standard mean difference = –2.90; 95% CI –4.61 to –1.49; p < 0.00001; I2 = 98%) following intraperitoneal or intrauterine surgery. Treatment lowered the rate of IUAs classified as moderate (RR 0.26; 95% CI 0.13–0.52; p = 0.13; I2 = 0%), but not those deemed mild (RR 0.86; 95% CI 0.62–1.21; p = 0.39; I2 = 3%) or severe (RR 0.33; 95% CI 0.03–3.09; p = 0.33; I2 = 0). Compliance with hyaluronic acid gel treatment was low. Conclusion: Hyaluronic acid gel can prevent IUAs, particularly those with moderate severity and a lower adhesion score.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
