Abstract

Low serum vitamin D and calcium levels as well as high parathyroid hormone (PTH) levels are the most important risk factors in osteoporosis. The aim of our study was to estimate the optimal vitamin D status needed to prevent a rise in PTH concentrations in postmenopausal women. Materials and methods: A total of 197 postmenopausal women who were at the menopausal period for at least 1 year and who had body mass indexes (BMIs) 70 years). Results: The mean age of patients was 60.8 ± 10.9 years. Serum 25-hydroxyvitamin D3 [25(OH)D3] levels were lower than 10 ng/mL in 94 patients (47.7%) and lower than 20 ng/mL in 167 (84.8%) patients. The mean vitamin D level was lowest in group 2 (51-60 years), but the difference was not statistically significant (P = 0.57). PTH levels were higher than 75 pg/dL in 52 patients, and 65.4% of those patients (n = 34) had vitamin D insufficiency (
