Effects of an incentive-based online physical activity intervention on health care costs

To test whether participation in an incentive-based online physical activity program for employees was associated with a moderation in health care costs.

Health care claims trends from 2003 to 2005 were analyzed among a matched sample of participants and nonparticipants. Medical and pharmacy costs, hospital inpatient costs, and emergency room costs were examined.

The average annual health care costs for participants increased by $291 per year compared with an increase of $360 for nonparticipants (P = 0.09). Higher levels of participation were associated with smaller increases in health care costs. Participants had a significantly smaller increase in inpatient hospital costs (+$20 vs +$119), heart disease costs ($-8 vs $46), and diabetic costs (+$1 vs +$16) compared with nonparticipants.
