|
The Purpose of this study is to compare the bone marrow density measured by quantitative ultrasonometry (QUS) between men and women. Questionnaires for general characteristics were obtained from 104 participants, and then their both calcaneus was measured by using QUS. Sex differences for bone marrow density (BMD) were analyzed by an Independent t-test using the SPSS 19.0 program. Of 104 participants, women and men were 69(66.3%) and 35(33.7%), respectively. T-value of left calcaneus was high significantly in women than that in men(0.443 vs. 0.031, p=0.161) as well as that of right calcaneus(0.555 vs. 0.049, p=0.093). T-value of right calcaneus was high than that of left calcaneus in women and men (not significant, p>0.05). T-value of both calcaneus was increasing with physical activity. T-value of calcaneus was no statistically significant with age and body mass index. The BMD of women is high significantly more than that of men, and BMD is relation with physical activity.
