Abstract

Background: Acute respiratory tract infections (ARIs) are a leading cause of pediatric morbidity and mortality worldwide, particularly in low- and middle-income countries. Emerging evidence suggests that Vitamin D plays a vital role in immune regulation, with its deficiency linked to increased susceptibility and severity of infections. However, the relationship between Vitamin D deficiency and ARI outcomes in children remains underexplored in developing regions like Pakistan.


Objective: The primary objective of this study was to determine the prevalence of Vitamin D deficiency among children presenting with ARIs. Secondary objectives included assessing the association between Vitamin D levels and ARI severity, as well as the demographic factors influencing this relationship.


Methods: A descriptive cross-sectional study was conducted at the Pediatrics Department of Kuwait Teaching Hospital, Peshawar, from January 1, 2023, to December 31, 2023. A total of 129 children aged 3 months to 5 years with ARI were recruited consecutively. Serum Vitamin D levels were measured using the enzyme-linked immunosorbent assay (ELISA) technique, with a deficiency defined as levels below 20 ng/mL. Data were analyzed using SPSS version 25.0, applying descriptive statistics, chi-square tests, t-tests, and logistic regression to evaluate the relationships between Vitamin D levels and clinical outcomes.


Results: Among the 129 children, 100 (77.5%) were found to be Vitamin D deficient. The mean serum Vitamin D level was 18.7 ng/mL (SD ± 6.3). A significant association was observed between Vitamin D deficiency and prolonged disease duration (>2 weeks) (p=0.000). Younger children (aged 3-12 months) and males were more likely to be Vitamin D deficient, with 84.4% of younger children affected (p=0.046). No major complications were reported, but Vitamin D-deficient children had a longer hospital stay.


Conclusion: This study demonstrates a high prevalence of Vitamin D deficiency among children presenting with ARIs, with deficiency associated with prolonged illness. These findings suggest the need for routine Vitamin D screening and potential supplementation to improve clinical outcomes in pediatric ARI cases.
