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 .

This study examined the predictive utility of self-efficacy and three types of outcome expectations (physical outcomes, social outcomes, and self-evaluative outcomes) on students' behavioral intentions and actual behaviors in a beginning weight training class. A total of 137 participants (62 men, 75 women; Mage = 21.4 yr., SD = 2.0) completed questionnaires assessing beliefs and intentions toward weight training. Attendance and workout log entries were used as a measure of actual behaviors. Regression analyses indicated that physical outcome expectations and self-efficacy emerged as significant predictors of students' behavioral intentions and actual behaviors. Findings of this study were interpreted from self-efficacy theory. [ABSTRACT FROM AUTHOR]

Objective. The purpose of this study was to investigate the effects of Qigong on type 2 diabetes mellitus (DM) using the systematic review and meta-analysis. Methods. All prospective, randomized, controlled clinical trials published in English or Chinese and involving the use of Qigong by patients with DM were searched in 7 electronic databases from their respective inception to June 2016. The meta-analysis was conducted using the Revman 5.2. The quality of the included trials was assessed using the Jadad rating scale. Two researchers independently completed the inclusion, data extraction, and quality assessment. Results. Twenty-one trials with 1326 patients met the inclusion criteria and were reviewed. The meta-analysis demonstrated that, compared with no exercise, the Qigong had significant effects on fasting blood glucose (MD = −0.99, 95% CI (−1.23, 0.75), P<0.0001), HbA1c (MD = −0.84, 95% CI (−1.02, −0.65), P<0.0001), and postprandial blood glucose (MD = −1.55, 95% CI (−2.19, −0.91), P<0.00001). Conclusion. The Qigong training can improve the blood glucose status of the type 2 DM patients and has positive effects on the management of type 2 DM. However, future research with better quality still needs to be conducted to address the effects of Qigong on type 2 DM. [ABSTRACT FROM AUTHOR]
