Association of IBM's "A Plan for Life" health promotion program with changes in employees' health risk status.

To evaluate the association of participation in IBM's "A Plan for Life" program with changes in blood pressure, serum total, high-density lipoprotein, and non-high-density lipoprotein cholesterol, body mass index, and cigarette smoking, we compared changes in these measures over a 1- to 5-year period among program participants and nonparticipants initially found to be at risk. After adjustment for age, sex, time to follow-up, and baseline values, the proportion of participants no longer at high risk was significantly greater than the corresponding proportion of nonparticipants in the areas of blood pressure total and non-high-density lipoprotein cholesterol and smoking cessation.
