Frequency of hospital acquired malnutrition at a tertiary care pediatric hospital.

Abstract

Objective: To determine the frequency of hospital acquired malnutrition in hospitalized pediatric population. Design: Cross-sectional study. Setting: Department of Pediatrics, National Institute of Child Health, Karachi, Pakistan. Period: January 2023 to June 2023. Methods: The inclusion criteria were children (irrespective of gender) aged between 1 and 12 years who were admitted for at least 48 hours. Weight of the children was measured daily from the time of admission to discharge. The hospital-acquired malnutrition rate was determined by dividing the patients with decreased weight-for-height (WFH) or body mass index (BMI) z-scores by total samples, then multiplying by 100. Results: In a total of 367 children, the mean age was 6.4±2.8 years whereas 203 (55.4%) children were boys. Hospital stays ranged from 2 to 19 days, with a mean of 18±6.9 days. At the time of discharge, the mean weight to be 17.6±6.53 kg, indicating a mean weight drop of 1.3±1.14 kg from admission to discharge. Weight reduction during hospitalization was observed in all age groups, with the highest percentage observed in children aged 2 to 5 years (77.7%) and the lowest in those aged 1 to 2 years (38.9%). Significant changes were observed in both WFH z-scores (mean difference -1.06, ± 1.69, p<0.001) for children under 60 months and BMI z-scores (mean difference -1.07, ± 4.63, p=0.023) for children over 60 months from admission to discharge. Conclusion: Hospital acquired malnutrition is common among pediatric patients and deteriorates when a child is hospitalized without attention to adequate nutritional support. Weight loss shows direct correlation with duration of hospitalization.
