Despite the health benefits associated with physical activity (PA), screen time reduction, and sleep quantity and quality, the relationships between PA, screen time, and sleep quantity and quality remain unclear in adolescents. The present study is a cross-sectional analysis of data from adolescents aged 16-19 years who participated in the 2005-2006 National Health and Nutrition Examination Survey ( = 542). Multivariable logistic regression models, adjusted for confounders, examined the relationship between objectively measured PA, self-reported screen time, and sleep quantity and quality. Respondents who met the current PA recommendation had 50% lower odds of having sufficient sleep (≥8 h) than those not meeting the recommendation (OR = 0.50, 95% CI: 0.26, 0.94). Respondents who met the screen time recommendation (≤2 h/day) had 55% lower odds of reporting poor sleep quality than those whose screen time exceeded the recommendation (OR = 0.45, 95% CI: 0.22, 0.91), with similar patterns observed for females and males. However, males who met both PA and screen time recommendations had 73% lower odds of reporting poor sleep quality than males who met neither recommendation (OR = 0.27, 95% CI: 0.07, 0.99). In conclusion, PA and screen time are associated with sleep quantity or sleep quality in adolescents, and there are differences in these associations by sex.
尽管身体活动 (PA)、减少屏幕时间以及睡眠数量和质量与健康益处相关，但在青少年中，PA、屏幕时间与睡眠数量和质量之间的关系仍不清楚。本研究是对 2005-2006 年全国健康和营养检查调查中 16-19 岁青少年数据的横断面分析( = 542)。多变量逻辑回归模型，调整了混杂因素，检查了客观测量的 PA、自我报告的屏幕时间与睡眠数量和质量之间的关系。与未达到推荐量的人相比，符合当前 PA 推荐量的人有 50%的可能性有足够的睡眠（≥8 小时）（OR = 0.50，95%CI：0.26，0.94）。符合屏幕时间推荐量（≤2 小时/天）的人报告睡眠质量差的可能性比超过推荐量的人低 55%（OR = 0.45，95%CI：0.22，0.91），女性和男性均有类似的模式。然而，既符合 PA 又符合屏幕时间推荐量的男性报告睡眠质量差的可能性比既不符合推荐量的男性低 73%（OR = 0.27，95%CI：0.07，0.99）。总之，PA 和屏幕时间与青少年的睡眠数量或睡眠质量有关，而且这些关联在性别上存在差异。
