RESUMO
OBJECTIVE: Diarrheal disease in under-five children among model families is expected to be lower than non-model families. Therefore, this study compared the prevalence and associated factors of diarrheal diseases among under-five children between model and non-model families. A comparative cross-sectional study was conducted from May to June 2017 among 322 children from each model and non-model family. Using multistage sampling technique data were collected through interview and observation. Both bi-variable and multivariable analyses were used to compute the statistical associations. Statistical significances were declared at 95% CI and p value < 0.05. RESULTS: Diarrheal disease in under-five children for those from model families was 26 (8.1%) and 65 (20.2%) to the non-model families with 95% CI 0.117, 0.168. Being non-model family (AOR = 1.9 and 95% CI 1.004, 3.565), maternal history of diarrhea (AOR = 3.3 and 95% CI 1.975, 5.570), improper waste disposal method (AOR = 2.6 and 95% CI 1.251, 5.578) and not latrine use (AOR = 2.1 and 95% CI 1.128, 3.897) were found determinant factors of diarrhea. Health extension model families training and follow up programs are needed to be expanded for all non-model families.
