Background: In addition to the dietary practice, access to improved water, sanitation, and hygienern(WASH) facilities contribute to child growth failure. However, the combined role of dietary practice andrnaccess to WASH on child growth outcomes is remains to be studied in rural Ethiopia. The aim of thisrnstudy was to assess the effect of complementary feeding and WASH practice towards child nutritionrnoutcomes.rnMethods: A community-based Cross-section study design was employed among rural householdsrn(n=464) having children 6-23months in south Wollo in Apirl 2021, using a multistage samplingrntechnique. Dietary assessment, anthropometric and biochemical (hemoglobin) measurements were done.rnWASH components were partly assessed through observation. Data were analyzed using Chi-square test,rnbivariate and multiple logistic regression using SPSS.rnResult: Children meeting the minimum dietary diversity was 25%. Proportion of household havingrnaccess to improved water source (56.3%), improved sanitation (16.6%) and hygiene (54.88). Only 6%rnof households satisfy for all the three combined WASH components. Regarding nutrition status ofrnchildren, stunting is more prevalent (44.2%), wasting (5.9%), underweight (14.7%) and anemia (63%).rnNon-breast children, mother height, fever. Diarrhea was associated with all components of WASH.rnHaving a mother with formal education was an advantage to meet MDD. Being in early age group of 6-rn11 months (AOR=2.33, 95% CI 1.49-3.57), having diarrhea episodes (AOR=1.59, 1.02-2.47) andrnexposing to the unimproved water source (AOR=1.57, 1.05-2.33) were associated with anemia. Factorsrnassociated with stunting: non-breast feeding (AOR= 2.6, 95% CI 1.08-6.3), increasing child age 12-rn23months (AOR= 1.56, 95% CI 1.05-2.31) and maternal height
