Answer

Similar rates of vitamin D deficiency have been reported in Europe [26] and Canada. A greater prevalence of vitamin D deficiency exists in Middle Eastern countries. A study of 316 young adults aged 30-50 years from the Middle East showed that 72.8% had 25(OH)D values of less than 15 ng/dL (that is, severely deficient). This was significantly more common in women than in men (83.9% vs 48.5%, respectively). The difference between sexes probably reflects the cultural and religious practices leading to less skin exposure in women than in men. [27, 28, 29, 30]
