1. After 2 years of employee participation, a computerized health risk assessment program managed by occupational health nurses was evaluated to determine whether health risk factor levels had undergone any significant change. 2. Data on 387 hospital employees were examined. Statistically significant reductions in risk factor levels were found for diastolic blood pressure, serum cholesterol, and smoking. The risk factor "weight" remained unchanged from year 1 to year 2 for both groups. 3. These findings suggest that the nursing interventions of focused, written feedback on risk factors, private counseling, and risk reduction education classes may have been important in motivating employees to make significant lifestyle changes.
