Abstract
Background: Providing universal access to safe water, sanitation and hygiene (WASH) in remote Nepal remains challenging. Efforts to improve WASH access in these areas are impeded by a dearth of information on the status of WASH conditions and its association with health and nutritional status of children in Nepal. Methods: We investigated WASH practices, nutritional status, and their association with intestinal parasitic infections, diarrhoea, undernutrition and clinical signs of nutritional deficiencies (hereafter health outcomes) during March to May 2018. Data was collected through cross-sectional survey of 1427 households, including questionnaires, observations, stool analysis, anthropometry, water quality measurements and assessment of clinical signs of nutritional deficiencies. Results: We found that 51.1% of children were suffering from intestinal parasitic infections and 55.5% had undernutrition; 52.2% had waterborne illnesses; and 63.9% had clinical signs of nutritional deficiencies. Multivariate mixed logistic regression analysis revealed significant associations between health outcomes and intermittent water supply (adjusted odds ratio (AOR)=2.72, 95% confidence intervals (CI)=1.18-6.31, P =0.02), washing hands when they look dirty (AOR=0.47, 95% CI=0.32-0.71, P =0.01), handwashing after going to toilet (AOR=0.37, 95% CI=0.13-1.02, P =0.06), cleanliness of the toilet (AOR=0.68, 95% CI=0.47-0.98, P =0.04), presence of earthen floor (AOR=2.29, 95% CI=1.20-4.37, P =0.01), caregivers who can read (AOR=4.07, 95% CI=1.00-16.55, P =0.05), no toilet (AOR=6.12, 95% CI=1.08-14.25, P =0.04), cleanliness of caregivers hand (AOR=0.61, 95% CI=0.41-0.89, P =0.01), regular deworming (AOR=0.44, 95% CI=0.20-0.94, P =0.03), own food production (AOR=0.67, 95% CI=0.46-0.97, P =0.03), animals inside the house overnight (AOR=1.71, 95% CI=1.17-2.51, P =0.01), source water quality (AOR=10.44, 95% CI=1.61-67.4, P =0.01), better socioeconomic status (AOR=0.43, 95% CI=0.25-0.75, P =0.01), and food supplements (AOR=0.57, 95% CI=0.38-0.84, P =0.01). Conclusions: Findings suggest improvements in WASH services, along with household hygiene and nutritional interventions, may together reduce child morbidity and mortality in Nepal.
