The social gradient in body weight (for example, obesity) departs from the social gradient in other health outcomes. Innovative approaches are needed to understand the observed patterns. This study examines time-use patterns by indicators of socio-economic position, and considers the implications of variations in time use for the social gradient in weight reported in other studies.
The data are from respondents aged 25 to 64 to Canada's 1986 and 2005 General Social Surveys, which focused on time use. Participation in various activities was examined by sex, and by personal income and education, stratified by sex, in both years.
Higher-income men and women were more likely than those of lower income to spend time in paid work, commuting and eating out, and less likely to spend time sleeping. Men and women with higher education were more likely than those with lower education to spend time in physical activity (2005 only) and reading. These time-use patterns plausibly contribute to the social gradient in obesity reported in other Canadian studies.
The findings suggest that there is value in looking beyond a narrow range of health behaviours toward broader measures of daily routines to gain insight into the social determinants of weight and health.
体重（例如肥胖）的社会梯度与其他健康结果的社会梯度不同。需要创新的方法来理解观察到的模式。本研究通过社会经济地位指标考察了时间利用模式，并考虑了时间利用变化对其他研究报告的体重社会梯度的影响。
这些数据来自加拿大 1986 年和 2005 年一般社会调查中年龄在 25 至 64 岁的受访者，该调查主要关注时间利用。按性别和个人收入及教育程度对各种活动的参与情况进行了分层分析，在这两年中都进行了分析。
高收入的男性和女性比低收入的男性和女性更有可能花时间在有薪工作、通勤和外出就餐上，而睡眠时间则更少。受教育程度较高的男性和女性比受教育程度较低的男性和女性更有可能从事体育活动（仅在 2005 年）和阅读。这些时间利用模式可能有助于解释其他加拿大研究报告中肥胖的社会梯度。
研究结果表明，除了关注健康行为的狭窄范围之外，更广泛地观察日常生活的常规措施，对于了解体重和健康的社会决定因素具有价值。
