    Background: The past two decades have witnessed a 60% decline in global malaria mortality. However, two thirds of all malaria deaths continue to occur among children <5 years, with a majority in the WHO African Region. Malnutrition is an important risk factor for malaria. Wasting, Stunting and Underweight are crucial indicators of malnutrition, and are associated with increased mortality in children <5. Annually, 14 million children <5 are classified as wasted and 59 million children are classified as stunted. Objective: The objective of this study is to look at nutritional parameters, weight-for-age (WAZ), height-for-age (HAZ), and weight-for-height (WHZ), and how they differ over time in children <5 with severe malaria (SM) from the Ugandan cities Mulago and Jinja and the outcomes of mortality and nutritional parameters, underweight, stunting, and wasting. Methods: We defined underweight, stunting, and wasting as 2SD below the WAZ, HAZ, and WHZ means. We evaluated Z-scores and mortality status from children <5 years enrolled in a prospective cohort study (NDI, Neurodevelopmental Impairment in Children with Severe Malaria) at enrollment and 12-month follow-up between two sites. Results: WAZ, HAZ and WHZ at baseline were significantly lower among SM groups than in CC (p<0.01), and the SM group maintained significantly lower WHZ (p<0.01) and HAZ (p<0.001) at 12-month follow-up. Among the children who died, there were no significant differences of nutritional markers in Mulago, but in Jinja there was found to be a significant association between mortality and low WAZ (p<0.05) and underweight (p<0.05). Of children classified as underweight in Jinja, 37.5% of them died compared to 15.9% who survived; additionally, the odds ratio for decreased WAZ and mortality was 0.58 (p<0.05). Conclusion: Underweight, stunting, and wasting may be risk factors for SM, and underweight may exacerbate poor mortality outcomes in rural areas like Jinja. While underweight is worsened among children with SM at 1 month and normalizes by 12 months, stunting remains persistently low at 12 months. Nutritional interventions must be aimed at maintaining linear growth throughout the first year of SM in children <5 to reduce the risk factor of underweight on poor mortality outcomes.
