High levels of sedentary behaviour have a negative impact on health and well-being. There is limited evidence on the prevalence and correlates of sedentary behaviour of adults with intellectual disabilities (ID).
A population-based sample of adults with ID were invited to take part in a comprehensive health check programme. Demographic and health data were collected during a structured interview and physical examination. Screen time was used as a proxy measure of sedentary behaviour. Bivariate and multivariate statistical modelling examined correlates of screen time.
Fifty per cent of the 725 participants reported four or more hours of screen time per day. Male gender, higher levels of intellectual ability, mobility problems, obesity, not having hearing impairment and not having epilepsy were all significantly associated with higher screen time in the final multivariate model (R = 0.16; Hosmer-Lemeshow goodness of fit statistic P = 0.36).
This is the first study to publish population-based data on the prevalence and correlates of sedentary behaviour in adults with ID. Compared with adults who do not have ID, adults with ID have higher levels, and different correlates, of sedentary behaviour. A better understanding of the social context of sedentary behaviour will inform the design of effective behaviour change programmes for adults with ID.
久坐行为水平较高对健康和幸福感有负面影响。关于智力残疾（ID）成年人久坐行为的流行程度和相关因素，证据有限。
邀请 ID 成年人的基于人群的样本参加全面健康检查计划。在结构化访谈和体检期间收集人口统计学和健康数据。屏幕时间被用作久坐行为的替代测量指标。使用双变量和多变量统计模型来研究屏幕时间的相关因素。
在 725 名参与者中，有 50%报告每天有四个多小时的屏幕时间。在最终的多变量模型中，男性性别、较高的智力水平、行动障碍、肥胖、没有听力障碍和没有癫痫都与较高的屏幕时间显著相关（R = 0.16；Hosmer-Lemeshow 拟合优度统计量 P = 0.36）。
这是第一项发表 ID 成年人久坐行为流行程度和相关因素的基于人群的研究。与没有 ID 的成年人相比，ID 成年人的久坐行为水平更高，且具有不同的相关因素。更深入地了解久坐行为的社会背景将为 ID 成年人的有效行为改变计划的设计提供信息。
