背景资料：身体活动（PA）模式可能会在年轻的成年期发生变化，与从青春期到成年期的过渡中发生的生活方式的变化相一致。本研究的目的是确定年轻女性在二十出头时经历的关键生活事件是否与不活动水平的增加有关。方法：这是对7281名参与者的4年随访（基线时年龄为18至23岁），自我报告测量PA、生活事件、体重指数（BMI），结果：横断面数据显示PA在基线（57%“活跃”）和随访（56%“活跃”）之间没有变化。然而，对于近40%的样本，PA类别在基线和随访之间发生了变化，其中约20%的女性从“活跃”变为“不活跃”，另外20%的女性从“不活跃”变为“活跃”。“在对年龄、其他社会人口学变量、BMI和基线PA进行调整后，报告结婚、生第一个或第二个孩子或开始有薪工作的妇女在随访时比那些没有报告这些事件的妇女更有可能不活动。结果表明，生活事件，如结婚，生孩子，和开始工作与年轻成年女性PA水平下降有关。当大多数女性经历这些关键的生命阶段转变时，需要制定策略来促进维持活动。
Background: Physical activity (PA) patterns are likely to change in young adulthood in line with changes in lifestyle that occur in the transition from adolescence to adulthood. The aim of this study was to ascertain whether key life events experienced by young women in their early twenties are associated with increasing levels of inactivity.Methods: This was a 4-year follow-up of 7281 participants (aged 18 to 23 years at baseline) in the Australian Longitudinal Study of Women's Health, with self-reported measures of PA, life events, body mass index (BMI), and sociodemographic variables.Results: The cross-sectional data indicated no change in PA between baseline (57% "active") and follow-up (56% "active"). However, for almost 40% of the sample, PA category changed between baseline and follow-up, with approximately 20% of the women changing from being "active" to "inactive," and another 20% changing from being "inactive" to "active." After adjustment for age, other sociodemographic variables, BMI, and PA at baseline, women who reported getting married, having a first or subsequent child, or beginning paid work were more likely to be inactive at follow-up than those who did not report these events.Conclusions: The results suggest that life events such as getting married, having children, and starting work are associated with decreased levels of PA in young adult women. Strategies are needed to promote maintenance of activity at the time when most women experience these key life-stage transitions.
