Abstract

|
|
background : To determine the relationship between nutrient intake and bone mineral density (BMD), we have investigated this issue by the use of a semiquantitative food-frequency questionnaire.
Methods : A total of 312 women aged 33-77 was divided into two groups, 187 premenopausal and 125 postmenopausal women. Dietary intake was assessed with a food-frequency questionnaire. DMD was assessed with dual-energy X-ray absorptiometry at the lumbar spine (lumbar vertebrae 2-4). Pearson correlation and
partial correlation coefficients were calculated for each nutrient at the lumbar spine BMD.
Results : The mean age of the 312 participants was 48 years, and their mean body mass index (BMI) was 23.7±2.8 ㎏/㎡. Forty percent of the women were in postmenopausal state. The mean lumbar BMD was 1.117g/㎠. Age was negatively correlated with BMD in postmenopausal women, but smoking and exercise were not correlated with BMD. In premenopausal women, nutrient intakes were not associated with BMD. A significant association was found between intakes of fat, iron, vitamin A, vitamin C and BMD in postmenopausal women, but after adjusting for age, body mass index, energy intake, smoking, exercise, and use of hormone replacement therapy, there was no association.
Conclusion : There was no significant association between nutrient intakes and BMD of the lumbar spine.
