A random sample of 517 employees was studied to determine differences in health care costs and absenteeism among exercisers and nonexercisers during the start-up of a corporate health and fitness program. Exercise was associated with decreased illness absence among female exercisers (47 v 69 hours, P less than .05) and there was a trend for illness absence to be inversely related to advancing age among exercisers, whereas illness absence increased among nonexercisers. Total health care costs among exercisers was lower (male $561, females $639) than among nonexercisers (male $1,003, females $1,535). Due to the large variation in the individual cost, the differences between exercisers and nonexercisers were not statistically significant. Ambulatory health care cost for nonexercisers (males $486, females $883) were significantly higher than the costs for exercisers (males $408, females $243). Because the differences were found upon program initiation, they were thought to be characteristics of exercisers and not due to exercise itself.
对517名员工进行了随机抽样研究，以确定在一项企业健康与健身计划启动期间，锻炼者与非锻炼者在医疗保健成本和缺勤率方面的差异。锻炼与女性锻炼者的病假天数减少有关（47小时对69小时，P小于0.05），并且在锻炼者中，病假天数有随年龄增长而呈负相关的趋势，而非锻炼者的病假天数增加。锻炼者的总体医疗保健成本（男性561美元，女性639美元）低于非锻炼者（男性1003美元，女性1535美元）。由于个体成本差异很大，锻炼者与非锻炼者之间的差异无统计学意义。非锻炼者的门诊医疗保健成本（男性486美元，女性883美元）显著高于锻炼者（男性408美元，女性243美元）。由于这些差异是在计划启动时发现的，因此被认为是锻炼者的特征，而非锻炼本身所致。
