Community based unmatched case-control study design was deployed to assess the relationship of severe acute malnutrition with water, sanitation, hygiene and other associated factors among under five children. Using systematic random sampling technique, a total of 296 under five children were enrolled from July 3 to August 30, 2023. Bi-variable and multivariable binary logistic regression analysis was done using SPSS version 21 to identify water, sanitation and hygiene factors associated with severe acute nutritional. Statistical significance was declared at P-value < 0.05. Water treatment [AOR:1.98,95%CI (1.152-3.413)], child hand washing after defecation [AOR:2.95, 95%CI (1.246-6.973)], marital status of the guardian [AOR: 3.57,95%ci (1.23-10.39)]and adequate breast milk [AOR: 2.05, 95 %CI (1.18-3.56)] were determinant factors significantly associated with child severe acute malnutrition. Thus, water treatment and hand washing after defection were the major water, sanitation, hygiene related factors statically associated with severe acute malnutrition. House hold water handling and treatment, proper child handing and continues behavioral change intervention on hygiene practice are recommended along with nutritional interventions.enwaterhygienesanitationsevere acute malnutrition and Addis Ababa.Thesis
