Frequency of weekly aerobic activity was compared with annual illness-related absenteeism in 79,070 adult US adult workers. Weekly exercise, days per week of aerobic activity (> or = 20 minutes), and absenteeism consisting of days per year and grouped as 1 to 3, 4 to 6, and 7+ days were recorded. After controlling for confounding variables, chi-squared values and odds ratios were calculated. A significant (chi 2 = 280.37) relationship was found between absenteeism and exercise. Differences (P < 0.05) in absenteeism were found between no exercise and all frequencies of weekly exercise. One day of exercise was associated with lower absenteeism when compared with no exercise, and 2 days of exercise was more favorable than one. No differences were found between any other combinations (2 to 3, 2 to 4+, 3 to 4+ days) of exercise frequency and absenteeism. These data suggest a significant relationship between exercise frequency and illness-related absenteeism.
对79070名美国成年工作者的每周有氧运动频率与年度因病缺勤情况进行了比较。记录了每周锻炼情况、每周进行有氧运动（≥20分钟）的天数，以及按每年缺勤天数分组为1至3天、4至6天和7天以上的缺勤情况。在控制混杂变量后，计算了卡方值和比值比。发现缺勤与锻炼之间存在显著关系（卡方 = 280.37）。未锻炼组与每周所有锻炼频率组之间的缺勤情况存在差异（P < 0.05）。与未锻炼相比，锻炼1天与较低的缺勤率相关，锻炼2天比锻炼1天更有利。在锻炼频率与缺勤情况的任何其他组合（2至3天、2至4天以上、3至4天以上）之间未发现差异。这些数据表明锻炼频率与因病缺勤之间存在显著关系。
