OBJECTIVE: To evaluate the effectiveness of a health promotion program in a retiree population in terms of health risk reduction and reduction in medical costs. DESIGN: Randomized controlled trial. SUBJECTS: Bank of America retirees (n = 4,712), divided into 33 retiree club regions, were randomized into 3 groups and followed for 24 months by patient report and claims experience. Group 1, the intervention group, received a low-cost ($30/year), individualized, serially reinforcing health promotion program including risk appraisal, recommendation letters, and self-management materials, delivered entirely through the mail. Group 2 received risk appraisals only, without feedback, for the first 12 months and subsequently the full intervention for the second 12 months. Group 3 was followed with claims data only. Participation rates of 57% at 1 year and 47% at 2 years were achieved. MAIN RESULTS: Overall health risk scores improved by 12% at 12 months compared with control (p < 0.001) and by 23% (from baseline) at 24 months (p < 0.001). Individual health habit changes were favorable for all parameters studied, and were highly statistically significant for most variables. Similar health risk reductions were seen in age groups of 55 to 65 years, 65 to 75 years, and over 75. Cost reduction differences were more than 20% by self-report (p < 0.01) and 10% by claims experience (p = 0.02) at 12 months. For the randomized controlled period of the first 12 months, reductions averaged $164 in the intervention group contrasted with an average increase of $15 in the combined control groups. CONCLUSION: Risk reduction programs directed at retiree populations can improve health risk status and can reduce costs.
