背景：虽然几十年来观察到的超重和肥胖的增加似乎已经趋于平稳，但有色人种儿童超重和肥胖的患病率仍然非常高。这篇文章估计了健康哈莱姆的健身-一个为期12周的课后计划，旨在帮助学生改善体育活动和饮食习惯-对青少年的BMI和体重状况的影响。方法：研究对象为纽约12个哈莱姆儿童区的436名超重或肥胖学生。该评估是一项随机对照试验，学生被分配到接受Get Fit加预防服务的干预组或仅在2013年或2014年接受预防服务的对照组。使用回归分析评估BMI z评分、超重或肥胖百分比以及肥胖百分比的影响。结果：相对于对照组，随机分配到Get Fit的学生的BMI z评分降低（平均差异= -0.04;p = 0.02）。超重或肥胖学生的百分比也较低（平均差异= -5.3;p = 0.02），但对肥胖学生的百分比没有影响。健身对女孩的BMI有影响，但对男孩没有影响。结论：Get Fit改善了初中和高中学生的BMI结果和体重状况。学校继续面临压力，要在满足学业要求的同时分配体育课和活动的时间，这突出了课后学生干预措施的重要性，如“健身”。
Background:Although the increases in overweight and obesity observed for several decades have appeared to have leveled off, the prevalence of overweight and obesity remains exceptionally high among children of color. This article estimates the effect of Healthy Harlem's Get Fit-a 12-week after-school program aimed at helping students improve physical activity and eating habits-on BMI and weight status of adolescents. Methods:Participants were 436 students who had overweight or obesity in 12 Harlem Children's Zone after-school programs in New York. The evaluation was a randomized controlled trial where students were assigned to an intervention group that received Get Fit plus Prevention services or a control group that only received Prevention services in 2013 or 2014. Impacts were assessed on BMI z-score, percentage with overweight or obesity, and percentage with obesity using regression analysis. Results:Relative to the control group, students randomized to Get Fit experienced a decrease in BMI z-score (mean difference = -0.04;p = 0.02). The percentage of students with overweight or obesity was also lower (mean difference = -5.3;p = 0.02), but there was no effect on the percentage of students with obesity. Get Fit had an impact on BMI for girls, but not boys. Conclusions:Get Fit improved middle- and high-school students' BMI outcomes and weight status. Schools continue to face pressure to allocate time for physical education and activity while meeting their academic demands, underscoring the importance of after-school student-level interventions like Get Fit.
