The purpose of this study was to examine the physical activity patterns of children with Down syndrome. A cross-sectional approach and accelerometry were used to measure the time children with Down syndrome (N = 104) spent in sedentary, light, and moderate-to-vigorous physical activity. Results indicated that adolescents from ages 14 to 15 years were the most sedentary and spent the least amount of time in light and moderate-to-vigorous physical activity. A general trend of decreasing physical activity as children increase in age was found. This trend is similar to that found among typically developing youth. Participants in this study were found to spend a majority of their day engaged in sedentary activities. Results indicate that most participants were not accumulating the recommended 60 minutes of moderate or vigorous physical activity.
本研究旨在考察唐氏综合征儿童的身体活动模式。采用横断面方法和加速度计来测量唐氏综合征儿童（N=104）的久坐时间、轻度活动时间和中高强度身体活动时间。结果表明，14 至 15 岁的青少年最为久坐，且花在轻度和中高强度身体活动的时间最少。随着儿童年龄的增长，身体活动量呈逐渐减少的趋势。这一趋势与典型发展青少年的趋势相似。本研究的参与者发现他们一天的大部分时间都在进行久坐活动。结果表明，大多数参与者没有达到建议的 60 分钟中高强度身体活动量。
