Employer-based health initiative: impact on employees' cardiovascular outcomes

BACKGROUND

Cardiovascular disease is the primary cause of mortality among men and women in the United States. The Ready, Set, Goal program was an employer-based initiative designed to identify individuals at risk for cardiovascular disease and to offer an intervention to alter those risk factors. The program involved cardiovascular education, screening, behavior-change incentives, continuing assessment, and follow-up. Pharmacologic treatment was not part of the intervention.

OBJECTIVE

To analyze the effects of the Ready, Set, Goal pilot program in 5 employers in the United States on salient cardiovascular end points for employees who completed the program.

METHODS

The analysis used a pretest/posttest within-subjects design to compare baseline measurements with measurements for all subjects who completed a second assessment 6 months after baseline measurements. Enrollment began in June 2004 in the first site and in May 2005 in the last site; it ended in January 2006. Patient clinical data from the pilot interventions were aggregated to assess the effects of the intervention on salient cardiovascular end points for individuals who completed the Ready, Set, Goal program. Changes in short-term cardiovascular risk factors were evaluated. Descriptive measures with paired t-tests (α = 0.05) were calculated at the aggregate level for each dependent variable. Range checks were conducted on all variables for clinical validity.

RESULTS

A total of 589 subjects from 5 employer group pilot interventions completed the program. Of these, 43% were men, 60% were white, 9% were African-American, 11% were Hispanic, and 20% were categorized as "other." After the intervention, mean blood pressure, total cholesterol, and low-density lipoprotein cholesterol levels were significantly lower (P <.05) compared with baseline measurements. On average, systolic blood pressure declined by 1.9 mm Hg; diastolic blood pressure by 1.3 mm Hg; total cholesterol decreased by 5.2 mg/dL and low-density lipoprotein cholesterol by 3.4 mg/dL. Triglyceride levels increased and high-density lipoprotein levels decreased, although these changes were not significant, and neither were the mean increases in body weight. But increases in body mass index were significant.

CONCLUSIONS

A worksite cardiovascular health program can have positive effects on salient cardiovascular end points for employees. The increases in triglyceridnes and body mass index should be further explored.
