To examine 1) associations between life events and changes in leisure-time physical activity (LTPA) in school leavers and 2) whether these associations are moderated by psychosocial factors.
Final year students (n=440) from high schools in rural Western Australia completed annual telephone interviews on three occasions; baseline (T1), one-year follow-up (T2; n=440) and two-year follow-up (T3; n=374). LTPA was measured using the Minnesota Leisure-time Physical Activity Questionnaire. Life events included moving out of home, working full-time and studying full-time. Psychosocial factors included enjoyment, self-efficacy, outcome expectations, club membership, and support from family and friends. Mixed linear regression models examined the effect of life events on changes in LTPA from T1 to T2 and T1 to T3.
A decline in LTPA across all time points was observed. Those who continued full-time education had a smaller LTPA decline than those who did not. Those who were not a member of a sporting club at T1 had greater LTPA decline if they worked full-time at T2.
There is a need for interventions to prevent declines in LTPA among school leavers, especially those who do not enter tertiary education. Encouraging sporting club membership during high school might be important.
1）研究离校学生生活事件与休闲时间体力活动（LTPA）变化之间的关联；2）这些关联是否受到心理社会因素的调节。
来自西澳大利亚农村地区高中的最后一年学生（n = 440）在三个时间点接受了年度电话访谈；基线（T1）、一年随访（T2；n = 440）和两年随访（T3；n = 374）。使用明尼苏达休闲时间体力活动问卷测量LTPA。生活事件包括搬离家、全职工作和全日制学习。心理社会因素包括享受程度、自我效能感、结果期望、俱乐部会员资格以及来自家人和朋友的支持。混合线性回归模型研究了生活事件对从T1到T2以及从T1到T3的LTPA变化的影响。
观察到所有时间点的LTPA均有所下降。继续接受全日制教育的学生的LTPA下降幅度小于未继续接受全日制教育的学生。在T1时不是体育俱乐部成员的学生，如果在T2时全职工作，其LTPA下降幅度更大。
需要采取干预措施来防止离校学生的LTPA下降，尤其是那些未进入高等教育的学生。鼓励高中阶段加入体育俱乐部可能很重要。
