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.
