| Abstract |
OBJECTIVE
Obesity is associated with alterations in vitamin D (VtD) system. We evaluated the correlation between VtD level and body mass index (BMI), a standard for the evaluation of obesity in postmenopausal women. METHODS: To study the relationship between VtD levels and obesity, we recruited 310 healthy postmenopausal women between January 2005 and March 2011 and analyzed the correlation between BMI and serum 25-hydroxyvitamin D (25-OH-VtD) level. We also analyzed the relationship between serum VtD level and bone health status such as bone mineral density measured by dual-energy X-ray absorptiometry, bone turnover marker, and parathyroid hormone (PTH). RESULTS: With a cut-off level for VtD deficiency at 30 ng/mL, 98.9% patients showed a VtD deficiency, while 87.8% patients showed a vitamin D deficiency with a 20-ng/mL cut-off level. VtD levels had no significant correlation with age, height, weight, BMI, or bone turnover markers. PTH level and serum 25-OH-VtD level showed a negative correlation. VtD level showed negative correlation with BMI, but statistically not significant. CONCLUSION: In this study, most of postmenopausal women (more than 87.8%) had a VtD deficiency, and VtD level showed negative correlation with BMI, but was not statistically significant. |
