Prevalence, Patterns, and Determinants of Malaria and Malnutrition in Douala, Cameroon: A Cross-Sectional Community-Based Study.

The overall prevalence of malaria was 18.9%, mostly asymptomatic cases. Malaria infection was associated with study site (p = 0.04), age (p = 0.01), WAZ (p = 0.0049), HAZ (p = 0.03), and BMI (p = 0.02). The overall prevalence of malnutrition was 43.1%, and stunting was the main form of malnutrition recorded in children under five years of age (23.6%). The risk of being stunted in this group was about quintupled in malaria-infected participants (ARR = 4.70; p = 0.02). In those aged 5-19 years, the prevalence of underweight was significantly higher in malaria-positive individuals as compared to their negative counterparts (p = 0.02). The overall prevalence of malaria and malnutrition cooccurrence was 8.5% and varied with age (p < 0.0001) and study site (p = 0.04). Conclusion and Recommendation. Malaria was associated with malnutrition among the study participants. Early detection and treatment of these ailments would reduce morbidity and mortality.
