Project in Tanna, Vanuatu
An Evaluation of a World Vision Water, Sanitation, and Hygiene (WASH) Project in Tanna, Vanuatu Alexandra Morrison A thesis submitted for the degree of Master of Public Health University of Otago, Dunedin, New Zealand 29th February 2016 ii Abstract Background In 2013, World Vision Vanuatu and World Vision New Zealand implemented a three-year water, sanitation, hygiene (WASH), and nutrition project (the Project) in south west Tanna, Vanuatu. The overall goal of the Project was to reduce child undernutrition, with short- and medium-term objectives to increase WASH infrastructure, and improve caregiver WASH and nutrition knowledge and practices. In January 2015, after two completed years of the Project, we designed and undertook an evaluation. Methods For households with children aged under five years of age in the Project villages we conducted: WASH and child health surveys; WASH infrastructure observations; anthropometric measurements of children under five years of age and their mothers; and microbiological drinking water testing. We compared our data with those gathered at baseline and at the end of year one of the Project. We undertook logistic regressions to investigate associations between: child health outcomes and WASH and nutrition factors; and household microbiologic water safety and WASH factors. Results Complete enumeration of households with children under five years of age was attempted. Overall, 220 households and 320 children participated in the evaluation. There was a significant increase over time in the proportion of households with access to improved latrines, from 39 (26.4%) of 148 households in 2013, to 202 (97.1%) of 208 in 2015 (p<0.001); and in the proportion of handwashing facilities from 31 (21.0%) of 148 in 2013, to iii 172 (82.7%) of 208 in 2015 (p<0.001).
