Their body height, weight, and waistline were effectively measured, and they were also evaluated to assess their body dissatisfaction, perception of dietary behaviors, and DBCWL. The correlation among these factors was analyzed using mediating effect models.Results The prevalence of overweight/obesity and abdominal obesity was significantly higher in males than in females(P < 0.05). Overweight/obesity, abdominal obesity, and body dissatisfaction significantly increased the risk for DBCWL(OR = 2.57, 2.77, and 1.95, respectively). Overweight/obesity and abdominal obesity significantly increased the risk for body dissatisfaction(OR = 6.00 and 4.70,respectively). Significant mediating effects of body dissatisfaction were observed in correlation between overweight/obesity and DBCWL and between abdominal obesity and DBCWL(OR = 2.20 and 1.92,respectively;P < 0.05), and the proportions of mediating effects among the total effects were 48.89% and 46.60%, respectively.Conclusion Body dissatisfaction might play an important mediating effect in association between DBCWL and obesity, which indicates that guiding children to correctly recognize their body might be more conducive than promoting obese children toward weight loss through dietary behavior changes.展开更多

Research identifying characteristics which predict WTLM success could be used to develop effective WTLM treatment programs. The purpose of this retrospective analysis was to determine behavioral (e.g., self monitoring of dietary intake) and biological factors (e.g., sex) which may influence WTLM success. Methods: In a previously conducted 12-month WTLM study, weight-reduced middle-aged and older men and women (n = 39) were assigned behavioral goals and asked to daily self-monitor body weight, fruit and vegetable intake, water consumption, and physical activity. This investigation utilized a crisp set qualitative comparative analysis (QCA) to characterize individuals’ weight changes and behaviors. Sex difference in clinically significant weight loss (WL) (≥5% WL) at 12 months was investigated, and growth curve models estimated interaction effects between sex and WTLM predictors. Results: QCA findings suggest patterns of weight change during the initial three months of WTLM treatment may dictate 12-month weight outcomes. No sex difference was found in clinically significant WL or in the interaction of sex and behaviors on weight change. Conclusions: WTLM treatments should provide more intensive support during transition from WL to WTLM, particularly during the first three months.展开更多

Methods: Coaches and clients who lost ≥ 10% body weight on the Program, had been trying to maintain their weight loss for ≥1 year, and maintained > 75% of their weight loss during that time were identified. Mean ± SD were calculated for continuous variables and categorical variables were quantified using frequencies and percentages. Results: The analysis included 590 respondents (342 coaches, 248 clients;84% female, 52.6 ± 11.9 years). Average weight loss was 23.7% ± 8.6%;average time in maintenance was 24.5 ± 15.8 months. The most common maintenance strategies included self-monitoring, leveraging habits learned during weight loss, food-related strategies, physical activity, establishing a healthy environment, and becoming a coach. Coaches identified several beneficial factors: higher accountability, increased self-awareness, paying it forward, aligning maintenance with their identity as a coach, being a role model, and engagement with the Program. Conclusions: Successful coaches and clients use behaviors consistent with existing literature combined with several unique to the Program. The novel insights from this research rest primarily on the strategy of becoming a coach to help maintain weight loss.展开更多
