Adults with intellectual disabilities (ID) typically have a sedentary lifestyle and higher rates of overweight and obesity. This study describes the habitual daily physical activity (PA) and the health-related physical fitness (PF) of adults with mild and moderate ID who resided in four group homes and worked in sheltered workshops. We also assessed the contribution of PF variables towards PA levels and sedentary behavior of this population subgroup. Adults with mild and moderate ID ( = 114) were assessed on PF tests (percent body fat, waist and hip circumferences, 6-min walk (6MWT), arm curl, and sit and reach). PA and sedentary behavior on weekdays were determined using Actigraph accelerometers. Results showed these adults averaged 2% of their daily time (or 10 min) engaged in moderate-to-vigorous PA (MVPA) and 67% of the time (495 min) being sedentary. No significant differences between mild and moderate ID were found for any PA or PF variable. Linear multiple regression analyses showed 6MWT to be the only significant PF variable contributing to the variance of PA and sedentary behavior. In conclusion, adults with ID reside in group home have low PA and low fitness levels. Among fitness variables, the walking test (i.e., cardiovascular fitness) had the highest positive association with participants’ daily PA, MVPA, and negative association with sedentary behavior. Future intervention studies in promoting PA and fitness for adults with ID are warranted.
成年人智力障碍（ID）通常生活习惯久坐不动，超重和肥胖的比例更高。本研究描述了居住在四个团体家庭并在庇护性工作坊工作的轻度和中度 ID 成年人的习惯性日常体力活动（PA）和与健康相关的身体适应性（PF）。我们还评估了 PF 变量对该人群亚组 PA 水平和久坐行为的贡献。对 114 名轻度和中度 ID 成年人进行了 PF 测试（体脂百分比、腰围和臀围、6 分钟步行测试（6MWT）、手臂卷曲和坐立前伸）。工作日的 PA 和久坐行为通过 Actigraph 加速度计进行测量。结果表明，这些成年人每天平均有 2%的时间（或 10 分钟）参与中等到剧烈的体力活动（MVPA），有 67%的时间（495 分钟）处于久坐状态。在任何 PA 或 PF 变量方面，轻度和中度 ID 之间均未发现显著差异。线性多元回归分析表明，6MWT 是唯一与 PA 和久坐行为的变异性相关的 PF 变量。总之，居住在团体家庭中的 ID 成年人的 PA 水平和适应性水平较低。在适应性变量中，步行测试（即心血管适应性）与参与者的日常 PA、MVPA 具有最高的正相关，与久坐行为具有最低的负相关。未来有必要对 ID 成年人进行促进 PA 和适应性的干预研究。
