Abstract
The purpose of this study was to determine the effectiveness of group nutrition and physical activity education classes in lowering cholesterol levels of worksite employees at 6-and 12-month intervals. A total of 32 participants were followed through the study. The group of participants included 24 female and 8 males, all over the age of 40.
The data were analyzed using one-way ANOV A with repeated n1easures, postĀ¬hoc analysis, Pearson's correlation coefficient, and ANCOV A to test six null hypotheses. Statistically significant differences in HDL cholesterol levels were found between baseline and 12 months (p=O.OOO) and between 6 months and 12 months (p=O.OOO). Statistically significant differences were also found in TCIHDL cholesterol ratios between baseline and 12 months (p=0.02) and between 6 months and 12 months (p=0.021).
