Breast cancer (BC) patients who undergo surgery followed by radiotherapy and chemotherapy have limitations on physical activity which will lead to a decreased quality of life and poor physical fitness level. The purpose of this study was to investigate the effects of the combined exercise intervention based on internet and social media software (CEIBISMS) on postoperative breast cancer patients by evaluating their quality of life, muscle strength and cardiorespiratory capacity. This study was a randomized control trial with an intervention period of 12 weeks. Sixty participants (30 in each group, 42–60 years old, female) were recruited through an outpatient department. Procedure of exercise in the intervention group included: 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 instruction of individuals on muscle training, three times per week; via social media apps daily push common knowledge of physical exercise BC rehabilitation. The control group received traditional treatment and rehabilitation according to daily specifications of the hospital. The primary outcome was quality of life and the secondary outcomes were muscle strength and cardiorespiratory capacity. Experiments using a Short Form 36 showed that the CEIBISMS yielded significantly better results than traditional methods, in vitality (p = 0.009), mental health (p = 0.001) and reported health transition (p = 0.048) by week 12. The CEIBISMS resulted in significant improvement in the stand-up and sit-down chair test (p < 0.0001), arm lifting test (p = 0.017). The CEIBISMS offered rehabilitative effects in quality of life (QOL) and muscle strength of postoperative patients with breast cancer (BC) in China. ChiCTR-IPR-17012368 .

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.

To examine, within a social-ecological framework, associations between multifaceted individual and environmental factors and habitual physical activity (HPA) among older Chinese adults. 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. 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. 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.

This study aimed to describe the most recent prevalence estimates of adolescent body mass index (BMI) and physical fitness from thirteen regions in Shandong Province, China and to examine differences by social-economic status (SES). The participants were 27,955 adolescents (mean age = 14.4 ± 1.8 years; 13,791 girls) enrolled from 91 public middle and high schools randomly selected from 13 administrative regions in Shandong Province. The Chinese National Student Physical Fitness Standard was employed to assess participants’ fitness once during the school semester. Fitness assessments included BMI, a 50-m sprint run, sit-and-reach, standing-broad jump, sit-ups, pull-ups, and a 1000 m/boy or 800 m/girl distance run. Participants’ fitness performance was categorized as excellent, good, pass, or no pass. The percent of Chinese adolescents categorized as “no pass” ranged from just 8.9% for BMI to 67.1% for boy pull-ups. The percent of Chinese adolescents categorized as “excellent” ranged from 5.0% for the girl sit-ups to 35.4% for the 50-m sprint run. Approximately 8.4% of the sample was categorized as excellent for BMI. SES significantly predicted both girl and boy continuous distance run scores (p < 0.05). Adolescents in lower SES strata had lower odds of achieving “pass” or better on cardio-respiratory endurance tests, muscular fitness tests, and flexibility tests, but higher odds of achieving “pass” or better on BMI compared to adolescents who were high SES (p < 0.05). The large sample of the adolescents in Shandong province, on average, had healthy weight status and achieved a high prevalence of “pass” or better on physical fitness tests. Adolescents who were low SES demonstrated poorer cardio-respiratory endurance, muscular fitness, and flexibility test achievement but better BMI achievement compared to high SES adolescents in Shandong Province, China.

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: Quality of life (QOL) is a crucial part of evaluating health conditions IN adolescents. The purposes of this study were to (1) examine the relationship of QOL and smoking, physical activity (PA) and screen time (ST) among Chinese adolescents, (2) explore the relationship between PA-ST combination and QOL of adolescents, and (3) investigate the dose-response relationship between PA-ST and QOL. Methods: This study randomly selected 12,900 adolescents (11–18 years) from 13 administrative regions in Shandong Province, China. The data gathering tools for Smoking (tobacco), PA (PAQ-A) and ST (average daily time for ST) and QOL questionnaire (child and adolescent quality of life scale) were completed among all adolescents. Statistical analysis was performed by T test, chi-square test and multiple linear regression. Results: 12,641 adolescents (aged 12–18) completed the study. In multiple linear regression models, the result demonstrated that the adolescents from rural areas, with high ST, low PA, and smoking, with older age and low socioeconomic status, showed a lower QOL score. First-time smokers under 10 years revealed the lowest QOL, and PA > 30 min five days per week have the highest QOL. In addition, boys and girls with PA > 30 min three to four days per week in high ST group obtain the higher scores (boys β = 5.951, girls β = 3.699) than low PA-low ST groups. Conclusions: Adolescents from rural areas suffer from a relatively poorer QOL. More than 30 min of PA five or more days for boys and three or four days per week for girls could decrease negative effects of ST and improve QOL.
