Abstract

Background:

Pulmonary infections remain a leading cause of pediatric morbidity and hospitalization in low- and middle-income settings, and undernutrition amplifies susceptibility to severe disease and complications.

 Objectives:

To evaluate the nutritional status of children admitted with pulmonary infections and to examine its association with infection patterns and short-term clinical outcomes.

 Methods:

A hospital-based observational study was conducted in one hundred children aged 1–14 years presenting with clinically diagnosed pulmonary infections. Anthropometry was recorded at admission, and nutritional status was categorized using age-appropriate indices. Pulmonary infection type and severity indicators (severe infection, duration of hospitalization, need for intravenous therapy, and complications) were documented. Group comparisons between children with normal nutrition and undernutrition were performed.

 Results:

The mean age was 6.4 ± 3.1 years, and 56% were boys. Undernutrition was present in 58% of children, including mild, moderate, and severe undernutrition in 18%, 26%, and 14%, respectively. Pneumonia was the most common infection pattern, observed in 52% of cases, followed by bronchopneumonia in 28% and recurrent lower respiratory tract infection in 14%. The distribution of infection type did not show a statistically significant association with nutritional status (χ²=3.99, df=3, p=0.263). However, severe infection was significantly more frequent among undernourished children than normally nourished children (55.2% vs 23.8%; χ²=9.84, df=1, p=0.002). Complications were also higher in the undernourished group (34.5% vs 14.3%; χ²=5.16, df=1, p=0.023). Mean hospital stay was significantly longer among undernourished children (7.1 ± 2.4 vs 4.2 ± 1.6 days; t=6.81, p<0.001).

 Conclusion:

Undernutrition was common among children hospitalized with pulmonary infections and was significantly associated with greater clinical severity, higher complication burden, and prolonged hospitalization.

 Recommendations:

Early nutritional screening and targeted nutritional support should be integrated into routine pediatric respiratory care pathways.
