Individual and community-level risk factors in under-five children diarrhea among agro-ecological zones in southwestern Ethiopia

Abstract

Under-five children diarrhea remains a major public health problem in resource-limited areas, including Ethiopia, due to multiple risk factors. This study aimed to identify individual and community-level risk factors affecting under-five children diarrhea (UFCD) in five districts of the Bench Maji Zone, southwestern Ethiopia. A community-based cross-sectional study was conducted from February to April 2018. A total of 826 households were recruited from five randomly selected districts using stratified sampling. A multivariable logistic regression model was fitted to identify risk factors associated with UFCD. The prevalence of UFCD in the study area was found to be 18.3%. Children less than six months of age are more at risk for diarrhea (95% CI for AOR2.5;1.23-4.90). Most probably initiating supplementary feedings before six months of age is one of the main risk factor for diarrhea (95% CI for AOR 0.65; 0.45-0.98). Similarly, mothers with low educational status (95% CI for AOR 0.30; 0.10-0.84), limited knowledge of mothers' about diarrhea (95% CI for AOR 0.24; 0.15-0.40), absence of hand washing among mothers/caregivers at critical times (95% CI for AOR 4.6; 2.88-7.67), and sharing of the residence with domestic animals (95% CI for AOR 2.87, 1.75-4.67) were the predictors of UFCD at individual-level. Children living in semi pastoral areas (95% CI for AOR 0.22; 0.10-0.50) unvaccinated children for rotavirus prevention (95% CI AOR 5.22, 3.33-8.20), households obtaining water from unimproved sources (95% CI for AOR 2.53; 1.60-4.40), and households with unimproved latrine facilities (95% CI for AOR 0.60; 0.33-0.99) were the risk factors of UFCD at the community-level. The study revealed that UFCD is a critical health concern in southwestern Ethiopia, where integrated intervention approach at individual and community level could help to alleviate the problem. At individual level, behavioral change intervention on handwashing, exclusive breast-feeding before the age of six months, and awareness on diarrhea prevention methods are critical areas of intervention. Likewise, provision of safe and adequate water source combined with household water chlorination, and vaccination for rotavirus are interventions at community that need to be integrated with the individual-level of intervention. This could significantly contribute for the reduction of UFCD in the resource limited areas through intersectoral collaboration of the health and other sectors.
