Abstract: Background: Vitamin D deficiency has been described in many diseases and indeed in the general population. However fewer reports have been published in young and healthy people. Vitamin D deficiency should not be found in medical students of the Canary Islands, because they have all the resources to avoid it. Objective: To estimate the prevalence of vitamin D deficiency in a population of medical students of both gender from the University of Las Palmas de Gran Canaria. Methods: 103 medical students of both genders from the University of Las Palmas de Gran Canaria. They completed a questionnaire and a physical examination. Vitamin D (25- hydroxycholecalciferol [25-HCC]), parathyroid hormone, biochemical markers of bone remodeling and a general biochemical study were performed. Bone mineral density was assessed by dual energy X-ray absorptiometry at the lumbar spine and the proximal femur. Quantitative ultrasounds parameters were measured at the calcaneus. Results: Only 38.8% of the students of Medicine (42.1% of males and 44.9% of females) have 25-HCC values higher than 30 ng/dl as widely recommended nowadays. Vitamin D deficiency (< 20 ng/ml) is observed in 32.6% and vitamin D insufficiency (< 30 ng/ml) in 28.6% of the students of Medicine in Las Palmas de Gran Canaria. Conclusion: Although they have optimal conditions for having good levels of vitamin D, near two thirds of the medical students in the Canaries have low values of vitamin D.
