研究背景：人们认为职业和业余时间的体育活动对健康有相似的益处。作者测试了这一hypothes.Methods丹麦员工（n=7144，52%的女性）的代表性样本报告的职业和休闲时间的体力活动水平在2005年。从2005 - 2007年的社会转移支付登记簿中检索出连续3周以上的长期病假。结果341名男性和620名女性在此期间经历了长期病假。调整了年龄、性别、吸烟、饮酒、体重指数、慢性病、来自直接上级的社会支持、情感需求、社会阶层和职业或休闲时间体力活动的考克斯分析显示，在中度抑郁的工人中，（HR 0.85，CI 0.72至1.01）和高（HR 0.77，CI 0.62至0.95）休闲时间体力活动的参考那些与低休闲时间体力活动。与此相反，中等（HR 1.59，CI 1.35 ~ 1.88）和高（HR 1.84，CI 1.55 ~ 2.18）职业体力活动的工人发生LTSA的危险性增加，与低职业体力活动的工人相比，差异有统计学意义（P <0.05）。以剂量反应的方式，职业体力活动增加LTSA的风险，而休闲时间的体力活动降低LTSA的风险。研究结果表明，职业和休闲时间的身体活动对全球健康的影响相反。
Background Occupational and leisure-time physical activity are considered to provide similar health benefits. The authors tested this hypothesis.Methods A representative sample of Danish employees (n=7144, 52% females) reported levels of occupational and leisure-time physical activity in 2005. Long-term sickness absence (LTSA) spells of >= 3 consecutive weeks were retrieved from a social-transfer payment register from 2005 to 2007.Results 341 men and 620 females experienced a spell of LTSA during the period. Cox analyses adjusted for age, gender, smoking, alcohol, body mass index, chronic disease, social support from immediate superior, emotional demands, social class and occupational or leisure-time physical activity showed a decreased risk for LTSA among workers with moderate (HR 0.85, CI 0.72 to 1.01) and high (HR 0.77, CI 0.62 to 0.95) leisure-time physical activity in reference to those with low leisure-time physical activity. In contrast, an increased risk for LTSA was shown among workers with moderate (HR 1.59, CI 1.35 to 1.88) and high (HR 1.84, CI 1.55 to 2.18) occupational physical activity referencing those with low occupational physical activity.Conclusion The hypothesis was rejected. In a dose-response manner, occupational physical activity increased the risk for LTSA, while leisure-time physical activity decreased the risk for LTSA. The findings indicate opposing effects of occupational and leisure-time physical activity on global health.
