Injury prevalence and associated costs among participants of an employee fitness program.

The prevalence, cost, and type of injury among participants of an employee fitness program and nonexercising co-workers were studied over a 2-year period from 1984 to 1985. The purpose of the study was to determine whether participants of an employee fitness program (n = 2,871) experienced a greater risk of injury and resultant higher costs than nonparticipants (n = 3,233). Overall, there were no significant differences in the rate or cost of injuries among the various participation levels (from 0 to 3 or more times per week). However, the data indicated that individuals who occasionally participated in the fitness program experienced a greater, but nonsignificant, risk of injury (6.3 per 100 persons who exercised less than 1 session per week, and 7.7 per 100 persons who exercised 1-2 sessions per week) than nonparticipants (5.7 per 100 persons). Injury prevalence was lower among individuals who exercised 3 or more sessions per week (5.4 per 100 persons) as was the resultant per capita cost of injuries ($32 vs $42 for nonparticipants). We conclude the impact of exercise at an onsite health and fitness facility on overall injury rates and costs among employees is negligible.

A preliminary investigation: effect of a corporate fitness program on absenteeism and health care cost.

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.
