肥胖儿童被随机分配到基于家庭的行为治疗中，其中包括刺激控制或强化以减少久坐行为。久坐行为和高能量密度食物显著减少，体力活动和水果蔬菜增加，标准体重指数(z-BMI)减少。在6个月(-1.21比-0.76)和12个月(-1.05比-0.51)时，用积极行为代替久坐行为的儿童z-BMI变化显著更大。身体活动取代久坐的行为和活动水平的变化可以预测6个月和12个月的z-BMI变化。结果表明，控制刺激和加强减少的久坐行为是减少久坐行为的等效方法，饮食和活动中的行为经济关系可能会中介治疗的效果。
Obese children were randomly assigned to a family-based behavioral treatment that included either stimulus control or reinforcement to reduce sedentary behaviors. Significant and equivalent decreases in sedentary behavior and high energy density foods, increases in physical activity and fruits and vegetables, and decreases in standardized body mass index (z-BMI) were observed. Children who substituted active for sedentary behaviors had significantly greater z-BMI changes at 6 (-1.21 vs. -0.76) and 12 (-1.05 vs. -0.51) months, respectively. Substitution of physically active for sedentary behaviors and changes in activity level predicted 6- and 12-month z-BMI changes. Results suggest stimulus control and reinforcing reduced sedentary behaviors are equivalent ways to decrease sedentary behaviors, and behavioral economic relationships in eating and activity may mediate the effects of treatment.
