Abstract
INTRODUCTION The aim of the current study was to assess the effectiveness of a nutrition education programme on post-menopausal women using self-reported nutrient intake data as well as a qualitative data obtained by the Healthy Eating Index (HEI). MATERIALS AND METHODS Seventy-five women (55-65 years old) were randomized to a dietary intervention group (IG: n=39), attending regular nutrition education sessions for 5 months and to a control group (CG: n=36). The intervention scheme was based on a combined application of the Health Belief Model and the Social Cognitive Theory, aiming to increase nutritional knowledge and self-efficacy of the subjects to adopt and maintain healthy dietary choices. Changes in self-reported macro- and micronutrients' intake as well as in the HEI total score and in its ten components were obtained. RESULTS The IG subjects reported increasing their milk (P<0.001) and total fat (P=0.01) HEI scores, decreasing total fat intake (P=0.050) and increasing calcium and vitamin D intakes (P<0.001 respectively) to a higher extent compared with the changes reported by the CG. CONCLUSION The current nutrition education programme appears to have induced favourable changes for the IG in micronutrients' intake primarily related to bone health and in total fat intake. These changes were reflected in the individual HEI indices but not in total HEI score.

Abstract
OBJECTIVE The aim of the current study was to examine whether a diet rich in dairy products followed by a nutrition education program for the prevention of osteoporosis could have any adverse effect on certain cardiovascular disease (CVD) risk factors over a 5-month intervention period. METHODS A total sample of 82 women (55-65 years old) was randomized to a dietary intervention group (IG: n=42), attending biweekly nutrition education program and provided with low-fat, fortified dairy products and to a control group (CG: n=40). Changes in dietary, biochemical and clinical indices related to CVD were determined at the end of the 5-month intervention period. RESULTS The IG was found to have a higher decrease in the percentage of energy intake derived from total fat and a higher increase in the intake of calcium, phosphorus, magnesium and potassium compared to the CG (p<0.05). Furthermore, the IG subjects were found to have a lower increase in BMI (0.7+/-0.1 versus 1.4+/-0.2 Kg/m(2), p=0.011) and systolic blood pressure (SBP) (2.5+/-2.9 versus 7.8+/-2.2 mmHg, p=0.040) and a higher decrease in serum total cholesterol (-5.2+/-3.3 versus 6.9+/-5.1 mg/dl, p=0.042) and LDL-cholesterol levels (-20.0+/-2.6 versus -12.4+/-4.2 mg/dl, p=0.034) compared to the CG. CONCLUSIONS The findings of the current study indicate that a dietary intervention aiming to minimize the risk for osteoporosis did not have any adverse effects on CVD risk factors. On the contrary, it has induced favourable changes in BMI, serum lipids and SBP.
