Determinants of Vitamin D deficiency among the adult population - An observational study

Abstract

Introduction and Aim: Vitamin D deficiency (VDD) has now become a scourge, and even in sunny areas in India, it is an increasing concern. The present study was prospective in nature and was carried over a period of two years (31st October 2019-1 st November 2020) at the wellness clinic in a medical college teaching hospital and research centre and was aimed to inquire the determinants of VDD in the representative sample. Material and Methods: The serum 25(OH) Vitamin D levels of subjects between the ages of 18 and 60 years were recorded along with their pertinent data. Statistical analysis was carried out using SPSS software v.23.0 and Microsoft Office 2007 to analyse the data. The non-parametric “Chi-square” test was applied to test any possible link between VDD and putative determinants. Results: VDD (25(OH) D levels< 50 nmol/L) was more common in the elderly (51-60 years), with a higher prevalence among females, in rural regions, and during the winter. Even the young and those with a normal BMI, exhibited significant vitamin D deficiency. Statistically significance was espied for age and VDD. Conclusion: VDD is very much colloquial in this locale, regardless of age, gender, BMI, seasonality, or urban/rural context. The statistics can help treating consultants understand the purview of the pandemic and develop strategy to improve gains in vitamin D levels on a community level.
