Research on the correlates of sedentary behaviour among adults is needed to design health interventions to modify this behaviour. This study explored the associations of social correlates with leisure-time sedentary behaviour of Canadian adults, and whether these associations differ between different types of sedentary behaviour. A sample of 12,021 Canadian adults was drawn from the 2012 Canadian Community Health Survey, and analyzed using binary logistic regression to model the relationships that marital status, the presence of children in the household, and social support have with overall time spent sitting, using a computer, playing video games, watching television, and reading during leisure time. Covariates included gender, age, education, income, employment status, perceived health, physical activity level, body mass index (BMI), and province or territory of residence. Extensive computer time was primarily negatively related to being in a common law relationship, and primarily positively related to being single/never married. Being single/never married was positively associated with extensive sitting time in men only. Having children under 12 in the household was protective against extensive video game and reading times. Increasing social support was negatively associated with extensive computer time in men and women, while among men increasing social support was positively associated with extensive sitting time. Computer, video game, television, and reading time have unique correlates among Canadian adults. Marital status, the presence of children in the household, and social support should be considered in future analyses of sedentary activities in adults.
需要对成年人久坐行为的相关因素进行研究，以设计健康干预措施来改变这种行为。本研究探讨了社会相关因素与加拿大成年人休闲时间久坐行为之间的关联，以及这些关联在不同类型的久坐行为之间是否存在差异。从2012年加拿大社区健康调查中抽取了12021名加拿大成年人作为样本，并使用二元逻辑回归分析来模拟婚姻状况、家庭中孩子的存在以及社会支持与休闲时间总体久坐时间、使用电脑时间、玩电子游戏时间、看电视时间和阅读时间之间的关系。协变量包括性别、年龄、教育程度、收入、就业状况、自我感知健康状况、身体活动水平、体重指数（BMI）以及居住的省份或地区。大量的电脑使用时间主要与处于普通法关系呈负相关，主要与单身/从未结婚呈正相关。单身/从未结婚仅与男性的大量久坐时间呈正相关。家中有12岁以下的孩子可预防大量的电子游戏和阅读时间。社会支持的增加与男性和女性的大量电脑使用时间呈负相关，而在男性中，社会支持的增加与大量久坐时间呈正相关。在加拿大成年人中，使用电脑、玩电子游戏、看电视和阅读时间有独特的相关因素。在未来对成年人久坐活动的分析中应考虑婚姻状况、家庭中孩子的存在以及社会支持。
