Life-transitions (e.g. parenthood) have been linked to physical inactivity, yet the topic requires further exploration. In this study, we evaluated changes in the physical activity (PA) of adults during their early career transition using retrospective analysis and the theory of planned behavior. Recruitment from January to March 2010 yielded a random sample of 267 assistant professors, ages 25-44, employed within the last five years. Repeated measures analysis of variance (RM ANOVA) concluded that PA declined across the transition (d = 0.36-0.43) and was further attenuated by marriage, work hours, and parenthood status. Discriminant function analysis (DFA) identified specific behavioral and control correlates about PA enjoyment, limited time, inconsistent schedule, work demands, and job pressures to distinguish between those who remained active from those who did not across the transition. PA interventions administered prior to career transitions may be needed to prevent physical inactivity.
人生阶段的转变（如为人父母）与身体活动减少有关，但该主题仍需要进一步探讨。在这项研究中，我们使用回顾性分析和计划行为理论评估了成年人在职业生涯早期过渡期间的身体活动（PA）变化。2010 年 1 月至 3 月期间招募了年龄在 25-44 岁、过去五年内任职的 267 名助理教授作为随机样本。重复测量方差分析（RM ANOVA）得出结论，PA 在过渡期间下降（d=0.36-0.43），并且婚姻、工作时间和父母身份进一步减弱了这种下降。判别函数分析（DFA）确定了关于 PA 享受、时间有限、时间表不一致、工作需求和工作压力的具体行为和控制相关性，以区分过渡期间保持活跃和不活跃的人。可能需要在职业转变前实施 PA 干预，以防止身体活动减少。
