Physical inactivity has been identified as a distinct health risk. However, little is known about how this can vary at leisure and work in cardiac patients. The aim of this study was to examine the prevalence and predictors of inactivity during leisure and work in the 12 months following a cardiac event in Australian cardiac patients.
A total of 346 patients consecutively admitted to hospital with acute coronary syndrome or to undergo coronary artery bypass graft surgery were interviewed in hospital, and 4 and 12 months later. Leisure and occupational physical activity was measured using the Stanford Brief Activity Survey. Sociodemographic, psychosocial, and clinical data were also collected.
The prevalence of leisure-time physical inactivity declined over time, with 52% inactive preevent and 29% inactive at 12 months. Approximately 50% of participants were physically inactive in their work, regardless of whether this was measured before or after the cardiac event. Logistic regression revealed that the significant predictors of leisure-time physical inactivity at 12 months were non-home ownership (OR = 2.19; P = .007) and physical inactivity in leisure-time prior to the event (OR = 2.44; P = .001). The significant predictors of occupational physical inactivity at 12 months were white-collar occupation (OR = 3.10; P < .001) and physical inactivity at work prior to the event (OR = 12.99; P < .001).
Preevent physical inactivity, socioeconomic, and clinical factors predicted both leisure and work inactivity after an acute cardiac event. Effective interventions could be designed and implemented to target those most at risk of being physically inactive at work or leisure.
身体活动不足已被确定为一个明显的健康风险。然而，人们对心脏病患者在闲暇和工作时身体活动不足的情况如何变化知之甚少。本研究旨在调查澳大利亚心脏病患者在发生心脏事件后的 12 个月内，闲暇时间和工作时不活动的发生率和预测因素。
连续纳入 346 例因急性冠状动脉综合征住院或行冠状动脉旁路移植术的患者，在入院时、术后 4 个月和 12 个月进行访谈。使用斯坦福简短活动调查问卷测量闲暇和职业体力活动。还收集了社会人口统计学、心理社会和临床数据。
随着时间的推移，闲暇时间体力活动不足的发生率下降，发病前有 52%的人不活跃，发病 12 个月后有 29%的人不活跃。约 50%的参与者在工作中身体不活跃，而不管这是在心脏事件之前还是之后测量的。Logistic 回归显示，12 个月时闲暇时间体力活动不足的显著预测因素是非自有住房（OR=2.19；P=0.007）和发病前闲暇时间体力活动不足（OR=2.44；P=0.001）。12 个月时职业体力活动不足的显著预测因素是白领职业（OR=3.10；P<0.001）和发病前工作时体力活动不足（OR=12.99；P<0.001）。
发病前体力活动不足、社会经济和临床因素预测了急性心脏事件后闲暇和工作时的不活动。可以设计和实施有效的干预措施，针对那些在工作或闲暇时最有可能不活跃的人。
