To examine the association between adherence to sleep, dietary, screen time, and physical activity (PA) (8-5-2-1-0) guidelines and risk of high body mass index (BMI ≥ 85 percentile) among U.S. adolescents and to assess for racial inequities and age-varying effects in these associations.
Data from the 2019 Youth Risk Behavior Surveillance System survey were used to conduct multivariable logistic regression models and moderation analysis by race/ethnicity and age using time-varying varying effect models (TVEM) and estimate associations of interest.
Of the 13,518 adolescents aged ≥ 14 years, only 0.5% met all guidelines. Adolescents adhering to sleep guidelines had a 21% reduction in their odds of having a high BMI (OR 0.79, 95% CI 0.67-0.93). Those adhering to PA guidelines had a 34% reduction in their odds of having a high BMI (OR 0.66, 95% CI 0.56-0.79), and those adhering to screen time guidelines had a 17% reduction in their odds of having a high BMI (OR 0.83, 95% CI 0.72-0.95). TVEM showed associations between adherence to sleep and screen time guidelines with high BMI fluctuate and are at specific ages. TVEM revealed substantial racial/ethnic differences in the age-varying association between adherence to 8-5-2-1-0 guidelines and high BMI throughout adolescence.
Associations between adherence to sleep and screen time guidelines and high BMI fluctuate with age, highlighting the need for nuanced interventions targeting 24-h movement guidelines (sleep, PA, and screen time) across adolescence, particularly given racial/ethnic disparities.
研究美国青少年遵守睡眠、饮食、屏幕时间和身体活动（PA）（8-5-2-1-0）指南与高体重指数（BMI≥第85百分位数）风险之间的关联，并评估这些关联中的种族不平等和年龄差异影响。
使用2019年青少年风险行为监测系统调查的数据，通过种族/族裔和年龄进行多变量逻辑回归模型和调节分析，采用时变效应模型（TVEM）并估计相关关联。
在13518名年龄≥14岁的青少年中，只有0.5%的人符合所有指南。遵守睡眠指南的青少年患高BMI的几率降低了21%（OR 0.79，95%CI 0.67-0.93）。遵守PA指南的青少年患高BMI的几率降低了34%（OR 0.66，95%CI 0.56-0.79），遵守屏幕时间指南的青少年患高BMI的几率降低了17%（OR 0.83，95%CI 0.72-0.95）。TVEM显示，遵守睡眠和屏幕时间指南与高BMI之间的关联会波动且在特定年龄出现。TVEM揭示了在整个青春期，遵守8-5-2-1-0指南与高BMI之间的年龄差异关联中存在显著的种族/族裔差异。
遵守睡眠和屏幕时间指南与高BMI之间的关联随年龄波动，这突出表明需要针对整个青春期的24小时运动指南（睡眠、PA和屏幕时间）进行细致入微的干预，特别是考虑到种族/族裔差异。
