BACKGROUND
We investigated the population trajectory of leisure time physical activity (LTPA) in adults age 18 to 60 y (n = 881), who were recruited in 1981 for the Canada Fitness Survey and followed-up through the Campbell's Survey on Well-Being (1988) and the Physical Activity Longitudinal Study (2002/04).
METHODS
Data on involvement in LTPA were collected by questionnaire and used to estimate average daily energy expenditure (EE) (kcal . kg-1 . d-1) during leisure time. Growth trajectory modeling was used to describe the overall population trajectory of LTPA and the extent to which average trajectories varied between sub-groups defined by age, sex, and education.
RESULTS
The population trajectory of LTPA over time was modified by baseline age, but not by sex or by level of education. Disparities in LTPA related to sex and education persisted over two decades.
CONCLUSION
This longitudinal investigation improves our understanding of the processes underlying patterns of LTPA in adults.
背景
我们调查了18至60岁成年人（n = 881）的休闲时间体力活动（LTPA）的人群轨迹，这些人于1981年被招募参加加拿大健身调查，并通过坎贝尔幸福感调查（1988年）和体力活动纵向研究（2002/04年）进行随访。
方法
通过问卷调查收集有关参与LTPA的数据，并用于估计休闲时间的平均每日能量消耗（EE）（千卡·千克⁻¹·天⁻¹）。使用生长轨迹模型来描述LTPA的总体人群轨迹，以及由年龄、性别和教育程度定义的亚组之间平均轨迹的变化程度。
结果
LTPA随时间的人群轨迹受到基线年龄的影响，但不受性别或教育程度的影响。与性别和教育相关的LTPA差异在二十多年间持续存在。
结论
这项纵向调查增进了我们对成年人LTPA模式背后过程的理解。
