In this study, serum lipid and cardiovascular risk levels of 195 military men and women were measured immediately before and 6 months after participation in a coronary artery risk evaluation (C.A.R.E.) program. Mean total cholesterol levels decreased from 257 mg/dl to 223 mg/dl (t(194) = -16.76, p = 0.00), low-density lipoprotein levels decreased from 170 mg/dl to 141 mg/dl (t(194) = -15.22, p = 0.00), and high-density lipoprotein levels increased from 45 mg/dl to 48 mg/dl (t(194) = 3.27, p = 0.01). Cardiovascular risk categories (based on serum lipid levels) were lowered from high to moderate risk in 54 subjects, high to low risk in 19 subjects, and moderate to low risk in 31 subjects (chi 2 = 98.28, p = 0.00). This study demonstrates that health education programs such as the C.A.R.E. Program can have a significant impact on serum lipid levels and cardiovascular risk levels and can potentially improve the health of high-risk populations.
