  1. Tailored Dietary Feedback (TF); Small Group Nutrition Education (GE) and Control Group (C) a Study group effects were examined using general linear models adjusted for gender, age and baseline dietary values bp values for dietary differences are based on t-tests after general linear models (ANCOVA), the a priori contrasts compared each intervention group with the control group **P < 0.05 based on paired t-test within study group results
