Recess has been shown to increase total daily energy expenditure, which may favorably impact body mass index by decreasing adiposity. This study examines associations between recess participation and adiposity.
The study sample included male (N = 1434) and female (N = 1409) children 5 to 11 years of age participating in the 2013-2016 National Health and Nutrition Examination Survey. Overweight and obesity were defined using age- and sex-specific percentiles. Recess participation interview questions were answered via proxy response.
Compared to a referent group participating in recess 5 days/week for >30 minutes/day and independent of demographic and behavioral factors, analysis revealed significantly greater odds of obesity in females reporting no recess participation (odds ratio 1.80; 95% confidence interval, 1.03-3.15, p = .03). Furthermore, minority females were consistently found to possess greater odds of overweight and obesity independent of recess participation time. Only Mexican American boys were found to have greater odds of obesity independent of participation recess time.
In a large nationally representative sample of US children, reporting no recess was associated with significantly greater odds of obesity in females. Minority females were also more likely to be overweight and obese and Mexican American boys are more likely to be obese independent of recess participation time.
课间休息已被证明能增加每日总能量消耗，这可能通过减少肥胖来对体重指数产生有利影响。本研究考察了课间休息参与度与肥胖之间的关联。
研究样本包括参加 2013-2016 年全国健康与营养调查的 5 至 11 岁男童（N=1434）和女童（N=1409）。超重和肥胖的定义采用年龄和性别特异性百分位数。通过代理回应回答课间休息参与度的访谈问题。
与参照组相比，每天 5 天/周、每天 30 分钟以上的课间休息参与度，分析显示，报告没有课间休息的女生肥胖的几率显著更高（比值比 1.80；95%置信区间，1.03-3.15，p=0.03）。此外，无论课间休息参与时间如何，少数族裔女性肥胖和超重的几率始终更高。只有墨西哥裔美国男孩无论课间休息参与时间如何，肥胖的几率都更高。
在一个具有代表性的美国儿童大样本中，报告没有课间休息与女生肥胖的几率显著增加有关。少数族裔女性也更有可能超重和肥胖，而墨西哥裔美国男孩无论课间休息参与时间如何，肥胖的几率都更高。
