Abstract
UNLABELLED: This study aimed to compare the vitamin D status in healthy Moroccan men and women aged 50 years and older. A total of 186 Moroccan women and 68 men, who had no previous diagnosis of osteoporosis, were recruited prospectively. We found in this study a high prevalence of hypovitaminosis D with no difference between men and women. PURPOSE: The main purpose of this study was to describe and compare the vitamin D status, parathormone, calcium, and phosphate of healthy Moroccan men and women aged 50 years and older. METHODS: We conducted two cross-sectional studies, in postmenopausal women from October 2008 to November 2009 and in men over 50 years old, from December 2009 to August 2010. A total of 186 Moroccan women and 68 men, who had no previous diagnosis of osteoporosis, were recruited prospectively. For the definition of hypovitaminosis D, the preferred level for 25-hydroxyvitamin D (25(OH)D) insufficiency, which is now recommended by many experts, is 30 ng/mL (75 nmol/L), and the levels below 10 ng/ml (25 nmol/L) indicate deficiency. RESULTS: The prevalence of vitamin D deficiency in men and women was 4.4 and 8.6 %, respectively, and the prevalence of vitamin D(25(OH) D) insufficiency in men and women were 85.2 and 77.4 %, respectively. In men and women, no correlations were found between intact parathormone (PTHi) and 25(OH) D (r = 0.056). CONCLUSIONS: Despite a sunny environment, we found in this study a high prevalence of hypovitaminosis D (insufficiency + deficiency) in Moroccan men over 50 years old and postmenopausal women.
