Physical activity (PA) during leisure time has been inversely associated with cardiovascular disease risk in the Western populations. We evaluated PA at work and leisure time in relation to acute myocardial infarction (AMI) in Chinese population. We conducted a hospital-based case-control study. The cases had first AMI (n = 2909). The controls (n = 2947) were matched to the cases in age and sex. The odds ratios (ORs) of leisure-time PA for strenuous exercise compared to mainly sedentary was 0.74 (95% confidence interval [CI]: 0.61-0.90) and for moderate exercise it was 0.96 (95% CI: 0.85-1.08). Multivariate adjustment did not substantially alter the association. The ORs of work-related PA for heavy PA compared to mainly sedentary was 1.44 (95% CI: 1.06-1.94), for climbing and lifting was 1.00 (95% CI: 0.77-.30), and for walking was 0.90 (95%CI: 0.75-1.07). Leisure-time PA was protective for AMI risk compared to sedentary lifestyles in a population in China.
在西方人群中，闲暇时间的身体活动（PA）与心血管疾病风险呈负相关。我们评估了中 国人在工作和闲暇时间的身体活动与急性心肌梗死（AMI）的关系。我们进行了一项基于医院的病例对照研究。病例组为首次 AMI（n = 2909）。对照组（n = 2947）与病例组在年龄和性别上相匹配。与主要久坐不动相比，剧烈运动的闲暇时间 PA 的比值比（OR）为 0.74（95%置信区间[CI]：0.61-0.90），适度运动的 OR 为 0.96（95%CI：0.85-1.08）。多变量调整并未显著改变这种关联。与主要久坐不动相比，与工作相关的 PA 中重度 PA 的 OR 为 1.44（95%CI：1.06-1.94），攀爬和举重的 OR 为 1.00（95%CI：0.77-0.30），步行的 OR 为 0.90（95%CI：0.75-1.07）。与久坐不动的生活方式相比，闲暇时间的身体活动对中国人群的 AMI 风险具有保护作用。
