To examine the effects of psychosocial working conditions and physical work demands on leisure time physical activity (LTPA).
Using path analysis, direct and indirect effects of self-reported working conditions on LTPA levels were assessed in a representative sample of 4167 workers from the 2000 to 2001 Canadian National Population Health Survey.
Higher levels of skill discretion and decision latitude were associated with higher LTPA. Physical work demands had opposite effects among men versus women, and skill discretion had a stronger effect among women than among men. Job security had a stronger effect on older workers and those without children younger than 13 years.
The results support the influence of the work environment on LTPA and suggest that certain work conditions should be targeted in future interventions seeking to impact participation in physical activity.
探讨社会心理工作条件和体力工作要求对闲暇时间体力活动（LTPA）的影响。
利用路径分析，评估了 2000 年至 2001 年加拿大全国人口健康调查中具有代表性的 4167 名工人样本中，自报工作条件对 LTPA 水平的直接和间接影响。
较高的技能判断和决策自由度与较高的 LTPA 水平相关。体力工作要求对男性和女性的影响相反，而技能判断对女性的影响大于男性。工作保障对年龄较大的工人和没有 13 岁以下子女的工人的影响更大。
研究结果支持工作环境对 LTPA 的影响，并表明在未来寻求影响体力活动参与的干预措施中，应针对某些工作条件。
