  • Title: [Hypovitaminosis D in postmenopausal women with low bone mineral density].
    Author: Rodríguez Portales JA.
    Journal: Rev Med Chil; 2001 Aug; 129(8):849-52. PubMed ID: 11680957.
    Abstract:
    BACKGROUND: Low vitamin D levels are a risk factor for osteoporosis. In the Northern hemisphere, a high frequency of low vitamin D levels has been detected. The correction of this deficit is associated with a lower fracture risk. AIM: To measure serum vitamin D levels in postmenopausal women with low bone mineral density. MATERIAL AND METHODS: 25-hydroxyvitamin D levels were measured in 40 postmenopausal women aged 50 to 74 years old, with a spine bone mineral density of less than 2 standard deviation of the values for young individuals. Serum calcium, phosphorus and calcium dietary intake were also measured. RESULTS: Mean serum 25-hydroxyvitamin D levels were 32.2 +/- 12.5 ng/ml. No correlation between vitamin D levels and other measured variables was observed. Using a cutoff value of 15 ng/ml, two women had low 25-hydroxyvitamin D levels. CONCLUSION: In this sample of postmenopausal women, vitamin D deficiency was infrequent.
