Participation in employer-sponsored wellness programs before and after retirement.

Objectives: To evaluate wellness program participation before and after retirement.

Methods: This retrospective cohort design compares 3 groups of employees: 1998-1999 retirees (N=6065), 1994-1995 retirees (N=5862), and 21,176 employees who were still active as of 2002. Participation was compared over 2 time periods for high-intensity and low-intensity programs.

Relationship of body mass index and physical activity to health care costs among employees.

This study examined the relationship between physical activity and health care costs by different weight groups. The study sample consisted of 23,490 active employees grouped into normal weight, overweight, and obese categories. After adjustment for covariates, physically moderately active (1 to 2 times/week) and very active (3 + times/week) employees had approximately $250 less paid health care costs annually than sedentary employees (0 time/week) across all weight categories.
