Sedentary behaviours have adverse health outcomes and adults with intellectual disabilities are at a higher risk of unhealthy lifestyle behaviours. The lack of knowledge relating to sedentary behaviours in adults with intellectual disabilities has impeded the development of effective interventions. This study aimed to investigate individual, interpersonal and environmental correlates that are associated with sedentary behaviours in adults with intellectual disabilities.
A secondary analysis of data from The UK Household Longitudinal Study (Understanding Society; collected 2011-2013) was conducted. Twenty-two predictor variables were included in a stepwise logistic regression, with TV hours during weekdays (≤3 and >3 h/day) used as a proxy for sedentary behaviours. A sample of 266 adults, with mean age of 37.9 and range from 18 to 49 years old, with intellectual disabilities were identified. Because 63.9% were female, 62.4% had children and 28.2% were employed, the sample is likely to be most representative of more able adults with intellectual disabilities.
A significant interaction term between having children and neighbourhood status was found in the initial model so separate models for good and poor-quality neighbourhoods are reported. Having children only had a significant effect to lower the odds of high TV time among participants living in good quality neighbourhoods (OR 0.10, 95% CI 0.03, 0.25). However, for people living in poor quality neighbourhoods it was better quality leisure services that was associated with lower odds of high TV time (OR 0.48, 95% CI 0.23, 0.90). Being employed only significantly reduced the odds of high TV time in the good quality neighbourhood model (OR 0.35, 95% CI 0.12, 0.78). These effects highlight the importance of environmental effects on lifestyle behaviours of adults with intellectual disabilities.
Future research should aim to expand our understanding of environmental effects on the sedentary behaviours and other lifestyle behaviours of adults with intellectual disabilities.
久坐行为对健康有不良影响，智障成年人有更高的不健康生活方式行为的风险。由于缺乏对智障成年人久坐行为的了解，有效的干预措施的发展受到了阻碍。本研究旨在调查与智障成年人久坐行为相关的个体、人际和环境相关性。
对英国家庭纵向研究（理解社会；2011-2013 年收集）的数据进行二次分析。将 22 个预测变量纳入逐步逻辑回归，工作日看电视时间（≤3 和>3 小时/天）用作久坐行为的替代指标。确定了 266 名年龄在 18 至 49 岁之间、有智力障碍的成年人样本。由于 63.9%是女性，62.4%有孩子，28.2%有工作，所以该样本可能最能代表更有能力的智障成年人。
在初始模型中发现了孩子的存在与邻里地位之间的显著交互作用项，因此报告了良好和较差邻里质量的单独模型。只有当孩子生活在高质量社区时，孩子的存在才会显著降低高电视时间的几率（OR0.10，95%CI0.03，0.25）。然而，对于生活在贫困社区的人来说，更好的休闲服务质量与较低的高电视时间几率相关（OR0.48，95%CI0.23，0.90）。只有在高质量社区模型中，就业才能显著降低高电视时间的几率（OR0.35，95%CI0.12，0.78）。这些影响突出了环境对智障成年人生活方式行为的重要性。
未来的研究应旨在扩大我们对环境对智障成年人久坐行为和其他生活方式行为的影响的理解。
