目的：主要目标是评估儿童体重控制计划中的性别差异，这些计划旨在增加体力活动（增加）或减少久坐行为和增加体力活动（结合）。第二个目标是评估的好处，以家庭为基础的干预措施对nontargeted siblings.Research方法和程序：67个家庭的肥胖儿童和89个兄弟姐妹被随机干预，有针对性地增加体力活动（增加）或减少久坐不动的行为和增加体力活动（结合）的组合。目标参与者和非目标的兄弟姐妹进行了为期1 year.Results：在12个月，男孩表现出显着更好的百分比超重的变化（-15.8%）的联合治疗比女孩（-1.0%），与男孩（-9.3%）或女孩（-7.6%）的增加干预没有显着差异。男孩的治疗依从性好于女孩（p < 0.01）。在多元回归分析中，坚持和倾向于体力活动是一年内有针对性的儿童体重减轻的重要预测因素。兄弟姐妹体重减轻的预测因素包括年龄，兄弟姐妹的数量，有针对性的儿童超重变化的百分比，和组分配的相互作用，由相同性别的治疗siblings.Discussion：性别可能会影响反应的程序，试图减少久坐不动的行为，和泛化的治疗效果的兄弟姐妹可能取决于干预和特点的兄弟姐妹。
Objective: The primary goal was to evaluate sex differences in child weight control programs that targeted increasing physical activity (increase) or the combination of reducing sedentary behavior and increasing physical activity (combined). A second goal was to evaluate the benefits of family-based interventions on nontargeted siblings.Research Methods and Procedures: Sixty-seven families with obese children and 89 siblings were randomized to interventions that targeted increasing physical activity (increase) or the combination of reducing sedentary behavior and increasing physical activity (combined). Targeted participants and nontargeted siblings were followed for 1 year.Results: At 12 months, boys showed significantly better percentages of overweight changes (- 15.8%) for the combined treatment than girls (- 1.0%), with no significant differences for the increase intervention for boys (-9.3%) or girls (- 7.6%). Boys adhered to treatment better than girls (p < 0.01). Adherence and predilection for physical activity were significant predictors of targeted child weight loss at I year in multiple regression analysis. Predictors of sibling weight loss included age, number of siblings, targeted child percentage of overweight change, and the interaction of group assignment by same sex of treated sibling.Discussion: Gender may influence response to programs that attempt to decrease sedentary behavior, and generalization of treatment effects to siblings may depend on the intervention and characteristics of the siblings.
