Childhood Malnutrition and the Association with Diarrhea, Water supply, Sanitation, and Hygiene Practices in Kersa and Omo Nada Districts of Jimma Zone, Ethiopia

Background: Inadequate water supply, sanitation, hygiene practices, and diarrhea are related to malnutrition, but there is limited evidence in Ethiopia about their association. Thus, the objective of this study was to describe childhood malnutrition and the association with diarrhea, water supply, sanitation and hygiene practices. Methods: A case-control study design was performed from December 2018 to January 2019 in Kersa and Omo Nada districts of the Jimma Zone, Ethiopia. Both children aged 6 to 59 months were chosen randomly from malnourished and well-nourished children in 128 cases and 256 controls, respectively. Bodyweight, length/height, mid-upper arm circumference, and presence of edema of the children were measured according to the WHO references. Then, the nutritional status of the children was identified as a case or control using the cutoff points recommended by the WHO. To see the association-dependent and independent variables, logistic regression analysis was used. Results: A total of 378 children were included in this study (98.44%). Malnutrition was significantly increased among children who delayed breastfeeding initiation(AOR = 3.12; 95% CI: 1.62-6.00), had diarrhea (AOR = 9.22; 95% CI: 5.25-16.20), were living in households indexed as the poorest (AOR = 2.50; 95% CI: 1.12-5.62), defecated in a pit latrine without slab/open pit (AOR = 2.49; 95% CI: 1.17-5.30), collecting drinking water from less than/equal to 1 km distance (AOR = 4.77; 95% CI: 1.01-22.71) and sometimes practiced hand washing at the critical times (AOR = 2.58; 95% CI: 1.16-5.74) compared with their counterparts. However, lactating during the survey (AOR = 0.35; 95% CI: 0.18-0.67), water collection from unprotected sources (AOR = 0.22; 95% CI: 0.05-0.95) and collection and disposal of under-5 children feces elsewhere (AOR = 0.06; 95% CI: 0.01-0.49) significantly reduced the likelihood of malnutrition. Conclusions: Early initiation of exclusive breastfeeding, diarrhea prevention, and the use of improved latrine and handwashing practices at critical times could be important variables to improve the nutritional status of children.
