Undernutrition significantly increases the risk of severe infections and mortality in children under five, particularly in low- and middle-income countries. Pneumonia, a leading cause of childhood death, is especially dangerous in undernourished children, yet prognostic measures to identify those at highest risk are lacking. To identify algorithms of poor prognosis in undernourished children with clinical pneumonia for early identification of children at risk for poor outcomes. This study analyzed a subset of children enrolled in a cohort designed to identify biomarkers of bacterial pneumonia. Children aged 2–59 months with clinical pneumonia were recruited from two rural Gambian hospitals. Clinical and anthropometric data were collected at baseline, during hospitalization, and at 30-day follow-up. Nutritional status was classified using WHO definitions for stunting (height-for-age Z-scores) and wasting (weight-for-height Z-scores) as severe (Z-scores ≤ -3), moderate (-2 ≥ Z-scores > -3), and mild (-1 ≥ Z-scores > -2). Prognostic outcomes were classified into good and poor. Poor prognosis included death, prolonged hospital stay (≥ 7 days), post-discharge care-seeking, and difficult to feed during admission. Good prognosis was based on a hospital stay 80% and area under the receiver operating characteristic curve ≥ 0.80. Furthermore, we identified accurate prognostic signatures among children with both wasting and stunting. Measures collected at admission in undernourished children with clinical pneumonia can identify those at risk of poor outcomes. The prognostic signatures developed in this study may inform early risk stratification and guide timely intervention, particularly in resource-limited settings.
