In postmenopausal women, it has been noted that heavier women conserve bone better than
those with lower body weight. The protective effect of obesity on bone mass has been ascribed
to a high body fat content. The present study of 123 postmenopausal women was undertaken to
determine the effects of obesity on sex hormone, FSH, SHBG, and BMD at lumbar spine of
Korean postmenopausal women. Our result revealed that obese group has greater bone mineral
density at lumbar spine than non-obese group. But, obese group was noted that have lower levels
of FSH and SHBG than non-obese group significantly. But, we couldnt find out the
differentiation of levels of estradiol between two groups. Age adjusted values for BMD at lumbar
spine, respectively, were positively correlated (r=0.219, p<0.05) with BMI. And levels of FSH,
adjusted with age, also revealed that have negative correlation (r=-0.243, p<0.05) with BMI. So,
we concluded that the protective effect of obesity on bone is related with FSH and SHBG, not
with estradiol.
