It is unclear whether children with Down syndrome have differing physical activity and sedentary behavior levels compared to typical children. This study addressed this evidence gap in a national sample. Physical activity/sedentary behavior were ascertained by parental report. Findings highlighted that children with Down syndrome were less likely to engage in regular physical activity compared to typical children and had the lowest likelihood of regular physical activity among all subgroups with developmental disabilities/special healthcare needs. Children with Down syndrome were also more likely to watch high volumes of television compared to typical children, although this was nonsignificant upon adjustment for general health. It was concluded that children with Down syndrome are in urgent need for interventions/programs that promote physical activity.

美国患有和未患有唐氏综合症的儿童的体育活动和久坐行为：全国儿童健康调查。

目前尚不清楚唐氏综合症儿童与典型儿童相比是否具有不同的身体活动和久坐行为水平。这项研究解决了国家样本中的这一证据差距。身体活动/久坐行为由父母报告确定。研究结果强调，与典型儿童相比，唐氏综合症儿童进行定期体育活动的可能性较小，并且在所有发育障碍/特殊医疗保健需求的亚组中，进行定期体育活动的可能性最低。与典型儿童相比，患有唐氏综合症的儿童也更有可能看大量电视，尽管根据一般健康状况进行调整后，这并不显着。
