Vitamin D status in medical students and risk factor analysis
Journal Title: Annals of Medical Physiology - Year 2018, Vol 2, Issue 1
Abstract
Vitamin D is finding increasing health implications beyond calcium homeostasis. Vitamin D deficiency is prevalent globally including India. Many asymptomatic individuals have hypovitaminosis implicating the need for intervention. The present study aimed at evaluating vitamin D levels among healthy medical students from southern India and its association with well-known risk factors. Hundred apparently healthy medical students between the age group of 18-25 years were recruited based on defined inclusion and exclusion criteria. A questionnaire form with details of sun exposure, tanning, milk intake, general health and drug history were obtained. Vitamin D levels were assessed by chemiluminescent immunoassay (CLIA). Vitamin D values were considered normal for 30-60 ng/ml, deficient for <20 ng/ml and insufficient for levels between 21-29 ng/ml. Majority of the students (89%) had deficient 25-hydroxyvitamin D levels while 8% of the student had insufficient and 3% of the students had sufficient 25-hydroxyvitamin D levels. The mean 25-hydroxyvitamin D level was 14.01±6.20 ng/ml, median level was 12.95 ng/ml and ranged between 5.15 to 43.01 ng/ml. No statistically significant association was noted with sex, BMI, sun exposure, dietary intake or serum calcium levels. To conclude, vitamin D deficiency is highly prevalent in asymptomatic medical students and showed lack of relationship with the well-defined risk factors in literature prompting to look for newer risk factors in this country.
