The impact of life events on physical activity (PA) is little understood.
The purpose of this study is to examine relationships between specific life events and changes in PA in three cohorts of Australian women.
Young (N = 7,173; age 22-27 years), mid-age (N = 8,762; 51-56 years), and older (N = 6,660; 73-78 years) participants in the Australian Longitudinal Study on Women's Health completed surveys on two occasions, 3 years apart.
About one third of the young and mid-age women and one quarter of the older women were "active" at both times. Decreasing PA was associated with marriage and childbirth in young women and with declining health in older women. Increasing PA was associated with retirement and death of spouse in the mid-age women. Stressful events such as divorce, harassment at work, and violence were also associated with changing PA.
There were significant associations between age-specific life events and PA changes. Understanding these relationships could inform interventions for preventing declines in activity at specific life stages.
生活事件对身体活动（PA）的影响鲜为人知。
本研究旨在探讨澳大利亚三组女性队列中特定生活事件与身体活动变化之间的关系。
参与澳大利亚女性健康纵向研究的年轻组（N = 7173；年龄22 - 27岁）、中年组（N = 8762；51 - 56岁）和老年组（N = 6660；73 - 78岁）参与者，在相隔3年的两个时间点完成了调查。
约三分之一的年轻和中年女性以及四分之一的老年女性在两个时间点均“活跃”。年轻女性身体活动减少与结婚和生育有关，老年女性身体活动减少与健康状况下降有关。中年女性身体活动增加与退休和配偶死亡有关。离婚、工作场所骚扰和暴力等压力事件也与身体活动变化有关。
特定年龄的生活事件与身体活动变化之间存在显著关联。了解这些关系可为预防特定生命阶段身体活动下降的干预措施提供依据。
