Relationship between Respiratory Tract Infections and Vitamin D Levels in Children

Abstract

Background and Aim: Acute respiratory tract infection are a major cause of global morbidity and mortality. Observational studies report consistent independent association between low serum concentration of 25-hydroxy-vitamin D and susceptibility to acute respiratory tract infection. The study aimed to compare the serum vitamin D levels in children experiencing various types of acute lower respiratory infections (ALRI) with those who were healthy, to explore any potential relationship between vitamin D status and respiratory health
