Based on the clinical trials and cohort studies in the Chinese population, this paper systematically summarized the association between weight/ body mass index (BMI) and their changes in preventing non-alcoholic fatty liver disease (NAFLD) and its adverse outcomes. The results showed that BMI was positively correlated with NAFLD risk, but for those with NAFLD, BMI was negatively related to the remission of NAFLD and there was a non-linear dose-response relationship between BMI and adverse outcomes. The lean NAFLD group had a higher risk of all-cause death, liver-related death, digestive system tumors, and obesity-related tumors than the overweight or obese NAFLD and lean non-NAFLD group. Additionally, the association between baseline BMI levels and adverse outcomes in NAFLD populations may be affected by other metabolic indicators. After controlling for baseline BMI, most studies suggested that weight loss could reduce the NAFLD risk. However, there is no consistent conclusion on how to control weight to prevent NAFLD because the methods and the time windows to assess BMI changes vary in different studies. Moreover, for those with NAFLD, limited evidence suggested the different relationship between weight loss and different outcomes. Therefore, we call for conducting multi-center cohort and experimental studies to verify the effect of weight control on NAFLD and its related adverse outcomes after considering the heterogeneity of NAFLD, so as to propose precision weight control recommendations.

Objective To investigate the effect and associated factors of multi⁃disciplinary team approach on weight loss in Chinese obese patients. Methods The multi⁃disciplinary team for obesity in Peking University First Hospital consists of 2 endocrinologists, 2 dieticians, 2 exercise therapists, a bariatric surgeon, an acupuncturist and several health educators. A total of 445 patients treated by multi⁃disciplinary team were recruited from June 2015 to June 2017, the mean age was (37.6±12.5) years old, with 293 females (65.8%) and 152 males (34.2%). Patients were followed up at 3, 6, 12, 18 and 24 months after their first visit. We analyzed body weight changes overs follow⁃up and factors that affected the successful rate in weight reduction using Logistic regression or chi⁃square analysis. Results Body weight declined significantly at each follow⁃up visit compared with baseline (P<0.01), and the reduction at 6 months and 12 months of follow⁃up were significant compared with corresponding former visit [6 months vs 3 months: (87.2±20.2) vs (87.8±19.8) kg, P<0.01; 12 months vs 6 months: (86.7±19.0) vs (87.2±20.2) kg, P<0.01]. Defining body weight reduction over 5% as success, the rate of success was as high as 40.9%－ 50.9% during visits. Defining the reduction of body weight over 10% as success, the successful rate gradually increased from 13.2% to 26.9% during visits. Female, baseline body mass index, waist circumference and weight reduction in early treatment phase were associated with weight⁃loss success rate (all P<0.01). There was no correlation between the use of metformin and weight⁃loss success rate (P>0.05). Conclusions A multi⁃disciplinary approach to manage obesity could significantly achieve the goal of body weight reduction. Female, baseline body mass index, waist circumference and weight reduction in early treatment phase are associated with successful weight control. [ABSTRACT FROM AUTHOR]

Introduction: Weight loss reduced the athlete's muscle mass and sport performance. However, some studies have suggested that resistance training could increase muscle mass and maintain strength performance for weight-loss athletes. The purpose of this study was to investigate the effects of resistance training on muscle mass and performance in weight-loss Taekwondo athletes. Methods: Twenty-six college Tae Kwon Do athletes were divided into no weight loss training group (NWLT, n = 7), weight loss training group (WLT, n = 9) and control group (Co, n = 10). Two training groups completed an 8 week resistance training program that included 2 training sessions per week. Co group did not lose weight and not involve in the resistance training course. Before and after the resistance training, the percentage of muscle mass and sport performance were evaluated. Data of baseline testing were analyzed using one-way ANOVA. Data also were analyzed by using mixed design of two-way ANOVA to compare the difference within groups, and the difference of training effects between groups. Result: Muscle mass, 1RM squat and 30 meters sprint were significant enhanced in NWLT group (p < .05). Five continuous countermovement jump, and the 30 meters sprint were significant reduced in WLT group (p < .05). Progress percentage of muscle mass and 30 meters sprint in NWLT group were significant higher than WLT group (p < .01). Progress percentage of 5 continuous countermovement jump was significant lower than NWLT group and Co group (p < .05). Conclusion: Resistance training only maintain weight-loss athletes' muscle mass, 1RM strength and explosive force of single jump, but unable to maintain sustained high power performance.

Background: Advances during the past decade have made it feasible to apply e-health methods to chronic disease management. Researchers have recently begun applying these methods to weight control. The application of e-health management methods to weight control in adolescents has yet to be investigated empirically. Purpose: This study conducted a systematic review of reports discussing the weight-control effects of e-health management in adolescents. Method: Researchers searched 6 electronic databases for relevant articles published between 1995 and April 2013. Data were collected using inclusion and exclusion criteria. A modified Jadad Scale was used to evaluate the quality of the identified articles. Results: Seven studies met the inclusion criterion of targeting adolescent subject populations. A total of 3728 adolescents and 1394 parents participated in these studies. The majority of participants were overweight girls and median participant ages ranged from 12.52 (SD = 3.15) to 15.31 (SD = 0.69). All studies reported that e-health management reduced body mass index and body fat percentage. Four studies indicate that e-health management may improve physical activity knowledge and skills. However, diet control outcomes among the seven studies varied. Conclusion: Empirical results demonstrate that e-health management significantly affects weight control. However, the effectiveness of log-in versus primary outcome indicators was inconclusive. Future studies should consider the use of incentives, reminder systems, and other strategies to enhance website usage. The development of an Internet-based, computer-tailored weight-management intervention for overweight adolescents and the development of an appropriate care model are recommended.

Objective: To analyze the weight recognition and control among women aged 15-49 in China., Methods: Data was from the China National Nutrition and Health Surveillance 2010-2013. Stratified multistage cluster sampling method was used. The data of 35 664(16 914 urban women and 18 750 rural women) 15-49 years old women of childbearing age was used. The basic information was collected by questionnaires. Physical measurement indexes such as height and weight were collected., Results: Among overweight and obese women of childbearing age, only 34. 9%(95%CI 34. 2%-35. 6%) of them correctly judged themselves overweight or obese, and 61. 4%(95% CI 60. 6%-62. 1%) of them thought they were normal weight; 10. 8%(95%CI10. 3%-11. 2%) of the normal-weight women thought they were overweight; while 3. 0%(95% CI 2. 6%-3. 4%) of the low-weight women thought they were overweight. Only17. 1%(95% CI 16. 4%-17. 8%) of overweight and obese women of childbearing age take weight control measures. In addition, 3. 6%(95% CI 3. 1%-4. 1%) of low-weight women of childbearing age and 9. 7%(95% CI 9. 3%-10. 1%) of normal-weight women took weight control measures, respectively. The proportion of women aged 15-24 taking weight control measures was higher than that of women aged 25-34 and 35-49, 14. 8%(95% CI 13. 3%-16. 4%), 12. 2%(95% CI 11. 1%-13. 2%) and 10. 0%(95% CI9. 3%-10. 1%), respectively. The proportion of women aged 15-24 taking weight control measures was the highest among normal weight women and overweight and obese women, 13. 9%(95% CI 13. 1%-14. 7%) and 26. 9%(95% CI 26. 4%-27. 4%), respectively., Conclusion: At present, there were more women of childbearing age in China who could not correctly assess their own body weight, leading to the inability to take correct weight control measures.
