Abstract：
Background: While socioeconomic status (SES) has been shown to be an important determinant of sedentary behaviour (SB) and moderate-to-vigorous intensity physical activity (MVPA) in typically developing children, similar data on those with intellectual disability (ID) are lacking. This study explored the association of SES with SB and MVPA among Chinese children with ID. Method: Data were collected from 275 children aged 7-16 with mild to severe ID. Children\'s Leisure Activities Study Survey assessed SB and MVPA for a week. SES was assessed using the six indicators. Multiple linear regression was used to analyse the associations of SES variables with SB and MVPA on schooldays and on weekends. Results: Parental education level was positively associated with SB on weekends, and MVPA on schooldays and weekends; family\'s combined annual income was positively associated MVPA on schooldays and weekends; parental occupation was positively associated with SB on schooldays and weekends; Family Affluence Scale was positively associated with SB on schooldays (all p < 0.05). Conclusion: SES plays a significant role in influencing SB and MVPA in children with ID. Results suggest that interventions should focus on increasing MVPA for children with lower SES, while families with higher SES should limit their children\'s SB.
摘要：
背景：虽然社会经济地位（SES）已被证明是久坐行为（SB）和中等至剧烈强度体力活动（MVPA）的重要决定因素，缺乏关于智障人士(ID)的类似数据。本研究探讨了中国ID儿童SES与SB和MVPA的相关性。方法：收集了275例7-16岁的轻度至重度ID儿童的数据。儿童休闲活动研究调查评估了一周的SB和MVPA。使用六个指标评估SES。使用多元线性回归分析学生日和周末SES变量与SB和MVPA的关联。结果：周末父母受教育程度与SB呈正相关，学生日和周末的MVPA；家庭综合年收入与学生日和周末的MVPA呈正相关；父母职业与学生日和周末的SB呈正相关；家庭富裕程度量表与学生日的SB呈正相关（均p<0.05）。结论:SES在影响ID患儿的SB和MVPA中起重要作用。结果表明，干预措施应侧重于增加SES较低儿童的MVPA，而SES较高的家庭应该限制他们孩子的SB。
