经常性的体育活动对青年人的健康益处很重要，但存在差异。本文描述了美国青少年参与体育活动和久坐行为的差异，提供了干预的意义，并为未来的研究提供了建议，重点是减少与体育活动水平相关的差异。对国家加速度计数据的二次分析显示，达到推荐的身体活动水平的亚组比例从2%到61%不等。平均每天花在久坐行为的时间从5.5到8.5不等。性别和年龄方面的差异最大。对相关因素的更好理解可以为干预措施的设计提供信息，以增加目标亚组的身体活动。需要更多基于理论的研究来阐明哪些导致身体活动差异的因素可以通过干预来改变。为了消除健康差距，可能需要改变对体育活动有影响的政策，以促进高危青年的体育活动。
Regular physical activity is important for health benefits among youth, but disparities exist. This paper describes disparities in physical activity participation and sedentary behaviors among youth in the United States, provides intervention implications, and offers recommendations for future research focused on reducing disparities related to levels of physical activity. Secondary analysis of national accelerometer data showed that achievement of recommended levels of physical activity ranged across subgroups from 2% to 61%. Mean hours per day spent in sedentary behavior ranged from 5.5 to 8.5. The largest disparities were by gender and age. An improved understanding of correlates may inform the design of interventions to increase physical activity in targeted subgroups. Additional theoretically based research is needed to elucidate which factors contributing to physical activity disparities are amenable to change via intervention. To eliminate health disparities, changes in policies that have an impact on physical activity may be necessary to promote physical activity among high-risk youth.
