Health risk appraisal and serum cholesterol nutrition education: an outcome study.

Records of 59 U.S. Army service members identified as at-risk for coronary heart disease were reviewed. Soldiers were divided into groups that completed and did not complete cholesterol nutrition education classes. Differences in the means of repeated cholesterol measures were compared within each group. Results showed statistically significant declines in total cholesterol, with t(35) = 2.94, p < 0.01 for the class completion group and t(22) = 2.18, p < 0.05 for the dropout group. Similar results were noted for low-density lipoprotein measures. However, cholesterol differences in the means between the two groups were not statistically significant. Results indicate that decreases in serum cholesterol may occur due to at-risk reactive behavior, but that full compliance with the current nutrition education program does not appear to further reduce cholesterol levels to any appreciable degree.
