Background and Aim In recent years, vitamin D deficiency has become a major worldwide problem that can exert harmful effects. The aim of the present study was to evaluate the sex‐ and age‐related prevalence of vitamin D deficiency in people from Mashhad, northeastern Iran. Methods In this cross‐sectional study conducted over a period of 1 year (2015‐2016), 7504 subjects who referred to Mashhad medical centers were randomly enrolled in the study. The study population was divided into four groups based on sex and age, as following: group 1, 6 to 18 years; group 2, 19 to 35 years; group 3, 36 to 50 years; and group 4, 51 to 65 years. Since vitamin D levels <10, 10 to 20, and 20 to 30 ng/mL are considered as severe, moderate, and mild deficiency, respectively, we used these criteria for categorizing our population. Results Of the total population in our study, 65.26% (4902; 57.81% of men and 72.07% of women) showed some degree of vitamin D deficiency. In addition, we found that vitamin D deficiency was common in all age groups (6‐18, 19‐35, 36‐50, and 51‐65 years), and more common in women (58.5%, 80.12%, 63.83%, and 88.44%, respectively) than men (41.66%, 59.86%, 44.97%, and 84.75%, respectively). Conclusion Vitamin D deficiency is a major health problem in all age groups and is more common in women. This information would help to provide a progressive prevention program to maintain health and manage some of the vitamin‐related disorders and diseases that especially affect women.
