To examine whether adherence to US sleep, dietary, screen time, and physical activity (8-5-2-1-0) guidelines is associated with reduced risk of overweight/obesity in adolescents.
Multivariable log-binomial regressions were estimated using the 2017 Youth Risk Behavior Surveillance System data.
Of the 8194 adolescents aged 13 years and older, only 0.6% (49) met all guidelines. Meeting the recommended 8 hours of sleep per day was associated with reduced risk of overweight/obesity (risk ratio [RR]: 0.90; confidence interval [CI]: 0.81-0.99). Having ≤2 hours of screen time per day was associated with reduced risks of overweight/obesity (RR: 0.85; CI: 0.77-0.95). One hour of daily physical activity was associated with reduced risk of overweight/obesity (RR: 0.80; CI: 0.73-0.87). No significant associations were found between daily consumption of ≥5 fruits and vegetables or consumption of zero sugar-sweetened beverages and overweight/obesity. The 8-5-2-1-0 constitutes an improved prediction model to explain the risk of overweight/obesity among adolescents compared with the 5-2-1-0 model (F = 4.80; P = .035).
Findings from this study suggest that meeting recommendations for sleep, screen time, and physical activity is associated with decreased risk of overweight/obesity in a large sample of adolescents. These are important factors to consider in the prevention and treatment of overweight/obesity in adolescents.
研究美国睡眠、饮食、屏幕时间和体力活动(8-5-2-1-0)指南的遵守情况是否与青少年超重/肥胖风险降低相关。
使用 2017 年青少年风险行为监测系统数据,估计多变量 log-binomial 回归。
在 8194 名 13 岁及以上的青少年中,只有 0.6%(49 人)符合所有指南。每天保证 8 小时睡眠时间与降低超重/肥胖风险相关(风险比 [RR]:0.90;置信区间 [CI]:0.81-0.99)。每天屏幕时间≤2 小时与降低超重/肥胖风险相关(RR:0.85;CI:0.77-0.95)。每天进行 1 小时的体力活动与降低超重/肥胖风险相关(RR:0.80;CI:0.73-0.87)。每天食用≥5 份水果和蔬菜或不饮用含糖饮料与超重/肥胖无关。与 5-2-1-0 模型相比,8-5-2-1-0 构成了一个改进的预测模型,可以解释青少年超重/肥胖的风险(F=4.80;P=0.035)。
本研究结果表明,在一个大型青少年样本中,满足睡眠、屏幕时间和体力活动的建议与降低超重/肥胖风险相关。这些是预防和治疗青少年超重/肥胖的重要因素。
