Abstract Title: 

Vitamin D deficiency and acute lower respiratory infections in children younger than 5 years: identification and treatment.

Abstract: 

INTRODUCTION: Acute lower respiratory infection (ALRI) is a leading cause of childhood mortality. Research suggests that vitamin D deficiency (VDD) puts children at risk for ALRI. The purpose of this review is to examine ALRI and VDD in children 5 years and younger. Common etiologies, diagnosis, prevention, treatment of ALRI, and recommendations for vitamin D supplementation are summarized.METHOD: Databases were searched for studies investigating VDD and ALRI in children. Independent reviewers assessed the internal validity of the studies.RESULTS: Of 18 studies examined, VDD was found to be associated with increased risk or severity of ALRI in 13 studies; associations were not found in 4 studies. In one study it was found that high maternal vitamin D levels was associated with ALRI in infants.DISCUSSION: Vitamin D supplementation is a low-cost, low-risk intervention that providers should consider for children, especially those at high risk for ALRI. Practitioners should follow current recommendations when prescribing vitamin D supplementation for infants and children.
