Abstract

High prevalence of vitamin D deficiency has been reported from Pakistan. Association of sociodemographic factors with vitamin D status has received little attention in this region. Therefore, we embarked on investigating the relationship of sociodemographic factors with vitamin D levels in a healthy Pakistani population. Venous blood from 226 healthy participants (age range 19-69 years) was collected and analyzed for serum concentrations of 25(OH) vitamin D [25(OH)D] and other related biomarkers. Demographic characteristics of the study participants were collected. Vitamin D deficiency (25(OH)D levels less than 20 ng/ml) was found to be 75% in this cohort. Gender, sunlight exposure and monthly household income emerged as predictors of hypovitaminosis D. Mean serum 25(OH)D levels in the groups with monthly household income less than Pakistani Rupees (PKR) 20,000, between PKR 20,000-50,000 and above PKR 50,000 were found to be 11.0±7.5, 13.9±9.6 and16.9±11.7 ng/ml, respectively. Using logistic regression the odds of having vitamin D deficiency was 3.22 (95% CI, 1.65-6.28) in the group with household income less than PKR 50,000 per month compared to the group with household income more than PKR 50,000 per month when the model was adjusted for gender and exposure to sunlight. There is an association between household income and hypovitaminosis D in a healthy Pakistani population.
