We investigated the effect of habitual exercise and/or dietary intakes on Stiffness value investigated at calcaneus by a quantitative ultrasound measurement in menopausal women. Based on result of answer on last menses divided (under 6months, over 6months), the participants were two groups : <6mo-group and ≧6mo-group. While forty-nine women exercised at least once a week over 12month (exercised-group ; E), and seventy-nine women had no exercised or exercised once a week up to 12 month (control-group ; C). As a result, following results were obtained.

1) Mean ages were significantly higher in the ≧6mo-group than in the <6mo-group. 29 women in the<6mo-group and twenty women in the ≧6mo-group had a habitual exercise.

2) Mean Stiffness values were significantly lower in the ≧6mo-group than in <6mo-group. Moreover, the Stiffness values in ≧6mo-group were significantly higher in E-group than in C-group.

3) The main effect of the menses on intakes in vitamin-D and small fishes, and the main effect of the habitual exercise on the intakes of beans, and the habitual exercise menses interaction effect in small fish intakes were statistically significant.

4) After adjusted by age and menses, estimated mean Stiffness values were significantly higher in E-group than in C-group. Furthermore, age and menses adjusted-intakes of beans increased significantly in E-group compared to those in C-group.

These results suggest that, bone loss might be induced not only by biological factors such as aging and menses, but also prevented by habitual physical activity.

The purpose of this study was to examine the effect of extracurricular activities regarding nutritional education for elementary school pupils (16 boys and 24 girls). We presented three activity programs. First, we decided on the target of self-sufficiency concerning food. We promoted the importance of eating food made in Japan, and local production for local consumption. The second program was an educational program for food hygiene. The elementary school pupils independently checked whether they washed their hands effectively using a hand washing checker. The third program aimed to increase their knowledge of vegetables, and we promoted the importance of seasonal production for seasonal consumption.

We also conducted a self-completed questionnaire survey, revealing that 93.3％ of boys and 95.2％ of girls had a habit of eating breakfast everyday.

Most participants were satisfied with this program because the contents were enjoyable and useful, and pertinent to their everyday lives. We suggest that this nutritional education program had a positive effect to motivate elementary school pupils to consider food and their own eating habits.
