Children and youth with intellectual disabilities (ID) are known to face obstacles to physical activity participation, yet the activity patterns of this population are not well characterized.
OBJECTIVE/HYPOTHESIS: In this study, time spent in moderate to vigorous physical activity (MVPA), type, and frequency of participation in physical activities were assessed in youth with ID and in a comparison group of typically developing (TD) youth.
Weekly participation in MVPA in 38 youth with ID and 60 TD youth was assessed via accelerometry. Participants were also administered an interview about the frequency and type of physical activities they engaged in over the past year.
After adjusting for age and sex, youth with ID spent significantly less time in MVPA (33.5 vs. 46.5 min/day, p = 0.03) and were less likely to meet the US Physical Activity Guidelines than TD youth (6% vs. 29%, p = 0.01). Although time in MVPA was lower in youth with ID, females with ID participated in physical activities more frequently than TD females (47.1 vs. 28.2 times/month, p = 0.008) and also reported engaging in a greater variety of physical activities (7.8 vs. 5.2 activities/year, p = 0.01). No differences between males in the frequency of physical activity participation or the number of activities performed were observed. Both groups reported walking/hiking and active video as top activities.
Findings emphasize the need for targeted efforts to increase MVPA in youth with ID.
已知智力障碍（ID）儿童和青少年在参与身体活动方面面临障碍，但该人群的活动模式尚未得到很好的描述。
目的/假设：本研究评估了 ID 青少年和典型发育（TD）青少年的中度至剧烈身体活动（MVPA）时间、参与身体活动的类型和频率。
通过加速度计评估 38 名 ID 青少年和 60 名 TD 青少年每周的 MVPA 参与情况。还对参与者进行了关于过去一年他们参与的身体活动的频率和类型的访谈。
调整年龄和性别后，ID 青少年的 MVPA 时间明显较少（33.5 分钟/天对 46.5 分钟/天，p=0.03），并且比 TD 青少年更不可能符合美国身体活动指南（6%对 29%，p=0.01）。尽管 ID 青少年的 MVPA 时间较低，但 ID 女性比 TD 女性更频繁地参加身体活动（47.1 次/月对 28.2 次/月，p=0.008），并且还报告参与了更多种类的身体活动（7.8 次/年对 5.2 次/年，p=0.01）。未观察到男性在身体活动参与频率或活动数量方面存在差异。两组都报告了步行/徒步旅行和积极的视频游戏是最受欢迎的活动。
研究结果强调需要针对 ID 青少年增加 MVPA 进行有针对性的努力。
