How can you make a difference?

The main purpose of this consultancy is to conduct statistical analysis of UNICEF early childhood longitudinal study data with a focus on WASH indicators. The consultant will perform secondary data analyses on the longitudinal database and the water quality subsample through longitudinal and cross-sectional analyses, and the results will be published in a target of four (4) peer-reviewed articles. The consultant will also support the WASH section in the statistical analyses planning of on-going and up-coming studies, with focus on the Cambodia WASH Accelerating Sanitation and Water for All (ASWA) grant.

- Assist the UNICEF WASH team with management of the longitudinal database and the water-quality sub-sample.

- Provide appropriate statistical input in the design, execution and analysis of the study.

- Research question 1: Investigate the association between water, sanitation and hygiene, as a composite score, with the child’s nutritional status in urban and rural Cambodia. The analysis with a cross-sectional design will include water quality data collected for a subsample of c. 800 HH. The analysis will aim to assess the relative contribution of different components of the WASH composite score to nutrition outcomes (stunting, wasting and underweight). The results will be submitted as a journal article.

- Research question 2: Analysis of the determinants of microbiological water quality at the point of use. Descriptive analysis on water (including water source type, water treatment method), sanitation (including type of toilet, open defecation) and hygiene conditions (handwashing with use of water and soap) in urban and rural areas of Cambodia.  Explore with a case-control analysis the association between area open defecation free status and water quality improvements at point of collection and point of use. Changes in microbiological water quality between point of collection and point of use will also be investigated as a proxy for household hygiene. The results will be submitted as a journal article.

- Research questions 3 and 4: Define two additional research questions after exploring the database. Potential questions could include: Which drinking water sources are more at risk to be contaminated? Is there an association with the presence of animals at the household level? Explore the morbidity database in relation to WASH conditions. Is oral hygiene a proxy for child’s personal hygiene? Is oral hygiene associated to diet intake and WASH practices? The results will be submitted as 1-2 journal articles.

- Ensure validity, applicability, efficiency and accuracy of the statistical methods and procedures used.

- Support the UNICEF WASH team in the development of operations and procedures for the data collection, verification and management of statistical data for on-going and up-coming studies and surveys including the baseline dataset of Cambodia WASH Accelerating Sanitation and Water for All (ASWA) grant.
