Abstract

Introduction Pneumonia is one of the major causes of death in children younger than age five, especially in developing countries. The World Health Organization recommends children from a developing country take zinc supplements. We conducted this study to explore the efficacy of zinc supplementation in alleviating symptoms and shortening of hospital stay in children with pneumonia. Materials and methods We conducted this prospective, randomized controlled trial in the Department of Pediatrics, Civil Hospital, Jamshoro. We included 100 children of both genders randomized into two equal groups of zinc-supplemented and non-zinc-supplemented study groups after informed consent was obtained from the parents and legal guardians. The participants were aged 28 days to five years and admitted in the hospital with pneumonia. We monitored for hypoxia, tachypnea, chest indrawing, and cyanosis, and we recorded the total length of hospital stay for each group. Results We found no significant difference in symptom changes (i.e., hypoxia, tachypnea, chest indrawing, and cyanosis) between the zinc and non-zinc groups. However, hospital length of stay was significantly shorter for patients in the zinc-supplemented group compared to the non-zinc-supplemented group. Conclusion Zinc supplementation did not yield a statistically significant reduction in symptoms in children with severe pneumonia. Zinc supplements given during an acute episode are not beneficial in short-term clinical recovery from severe pneumonia in hospitalized children.
