The purpose of this study was to examine the relationship between bone mineral density (BMD) and past dietary habits of middle-aged and elderly women who were hig-risk population of osteoporosis. We examined dietary habits of 713 women aged 50 years and over who underwent a check-up for osteoporosis at two public health centers in Ibaraki Prefecture. Items examined were frequency of intake of milk, cheese, yogurt, small fish, eggs, cooked beans, tofu, natto, vegetables and seaweed in their 20's, 30's and 40's. GS/D values were used as the indicator of BMD. Women with GS/D values less than 2.3 were designated as the low BMD group, and those with GS/D values more than 2.3 were designated as the control group. The differences in the intake frequencies of the aforementioned foods by the two groups were evaluated by chi-square tests. The results of our study showed that each proportion of people who consumed milk, small fish or seaweed every day in their 30's and 40's, and also in their 20's for the case of milk, was higher in the control group significantly. It was also indicated that each proportion of people who consumed tofu or vegetable more than three times in a week was higher in the control group. Those who consumed little of each kind of food little were seen in the low BMD group. It was concluded that there was a relationship between BMD and dietary habits related to calcium intake.
