INTRODUCTION
The prevalence of depression among US adolescents has increased during the past decade. Previous studies found relationships among physical activity, sedentary behavior, and depression, but more recent information is needed to inform research and practice. We used national surveillance data to assess the association of physical activity and sedentary behavior with depressive symptoms among US high school students.
METHODS
This study included 13,526 high school students from the 2019 Youth Risk Behavior Survey. The dependent variable was the presence of depressive symptoms in the past year that lasted almost every day for at least 2 weeks in a row and interfered with usual activities. The independent variables were physical activity (overall activity, muscle-strengthening exercises, participation on sports teams) and sedentary behavior (watching television, using a computer or digital device). We used weighted multivariable logistic regression to evaluate the association of physical activity and sedentary behavior variables with depressive symptoms, while controlling for demographic characteristics and other health behaviors.
RESULTS
The prevalence of depressive symptoms was 36.7%. Participating in physical activity 5 or more days in the past 7 days (adjusted odds ratio [aOR], 0.81; 95% CI, 0.68-0.97) and participating on 1 or more sports teams in the past year (aOR, 0.66; 95% CI, 0.55-0.78) were associated with reduced odds of depressive symptoms. Using a computer or digital device for 3 or more hours per school night was associated with higher odds of reporting depressive symptoms (aOR, 1.61; 95% CI, 1.41-1.85).
CONCLUSION
Inadequate physical activity and excessive sedentary behavior are associated with depressive symptoms among US high school students. Interventions targeting physical activity and sedentary behavior may be a public health strategy to reduce depressive symptoms in this population.
引言
过去十年，美国青少年的抑郁患病率有所增加。之前的研究发现了身体活动、久坐行为与抑郁之间的关系，但需要更多最新信息来为研究和实践提供依据。我们使用国家监测数据评估了美国高中生身体活动和久坐行为与抑郁症状之间的关系。
方法
这项研究纳入了来自 2019 年青少年风险行为调查的 13526 名高中生。因变量为过去一年中几乎每天都持续至少 2 周且干扰日常活动的抑郁症状。自变量为身体活动（总体活动、肌肉强化运动、参加运动队）和久坐行为（看电视、使用电脑或数字设备）。我们使用加权多变量逻辑回归评估身体活动和久坐行为变量与抑郁症状的关联，同时控制人口统计学特征和其他健康行为。
结果
抑郁症状的患病率为 36.7%。过去 7 天内每天进行 5 天或以上身体活动（调整后的优势比 [aOR]，0.81；95%CI，0.68-0.97）和过去 1 年参加 1 次或更多运动队（aOR，0.66；95%CI，0.55-0.78）与抑郁症状的发生几率降低相关。每晚上学期间使用电脑或数字设备 3 小时或以上与报告抑郁症状的几率较高相关（aOR，1.61；95%CI，1.41-1.85）。
结论
身体活动不足和久坐行为过多与美国高中生的抑郁症状相关。针对身体活动和久坐行为的干预措施可能是减少该人群抑郁症状的公共卫生策略。
