<p>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.</p><p>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.</p><p>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.</p><p>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.</p><p>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.</p><p>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.</p>
