This study aims to (1) describe participation in four physical activity (PA) domains across life and (2) examine the influence of PA during adolescence, early, middle, and later adulthood on health variables at older age. This observational study was conducted in 1378 generally healthy older adults (age 67-84 at baseline in 2003-2005; 52% women) in Quebec, Canada. Using a modified version of the interviewer-administered Lifetime Total Physical Activity Questionnaire (LTPAQ) and life events calendar to facilitate the recall, participants reported the frequency, duration, and intensity of occupational (OPA), commuting (CPA), household (HPA), and leisure time (LTPA) they participated in at age 15, 25, 45, and 65, and at the first follow-up (age 68-85 in 2005-2006). Fat mass, lean body mass, body mass index, waist-to-hip ratio, fasting glucose, systolic and diastolic blood pressures, self-reported chronic diseases, and socio-demographic data were assessed at baseline. Changes in PA over time differed by sex in each domain. However, there was a general decline in all PA domains in both sexes after age 65. In multiple regression analyses, LTPA at first-follow-up was associated with more favourable waist-to-hip ratio in both sexes, fat mass in women and fat mass percentage in men, whereas CPA, OPA, and HPA across life were not consistently associated with health variables. Older adults' LTPA at first follow-up was related to health variables, but PA recalled during adolescence, early adulthood, and mid-life was not. Results support the idea that current PA is positively related to better health outcomes.
（1）描述一生中参与四个身体活动（PA）领域的情况；（2）考察青少年期、成年早期、中期和后期的身体活动对老年时健康变量的影响。这项观察性研究在加拿大魁北克的1378名一般健康的老年人中进行（2003 - 2005年基线年龄为67 - 84岁；女性占52%）。使用经过修改的由访谈员实施的终生总体身体活动问卷（LTPAQ）和生活事件日历以促进回忆，参与者报告了他们在15岁、25岁、45岁和65岁以及首次随访时（2005 - 2006年年龄为68 - 85岁）参与职业（OPA）、通勤（CPA）、家务（HPA）和休闲时间（LTPA）活动的频率、持续时间和强度。在基线时评估了体脂、瘦体重、体重指数、腰臀比、空腹血糖、收缩压和舒张压、自我报告的慢性病以及社会人口统计学数据。各领域中身体活动随时间的变化在性别上存在差异。然而，65岁以后两性在所有身体活动领域均普遍下降。在多元回归分析中，首次随访时的休闲时间身体活动与两性更有利的腰臀比、女性的体脂和男性的体脂百分比相关，而一生中的通勤、职业和家务身体活动与健康变量并非始终相关。老年人首次随访时的休闲时间身体活动与健康变量相关，但青少年期、成年早期和中年期回忆起的身体活动则不然。结果支持当前身体活动与更好的健康结果呈正相关这一观点。
