Plain English Summary
Background and study aims
Complementary nutrition, WASH and school garden interventions can play an important role in improving health outcomes of children in developing countries. They consist in the improvement of water and sanitary environments at school and household level, education to promote dietary and hygienic behaviour, and the improvement of school-feeding programmes. However, we are not sure whether these complementary and integrated interventions help improve health outcomes of children in developing countries and the aim of this study is to find out more about it.
Who can participate?
School children aged 8 to 14 in selected schools in Burkina Faso and Nepal.
What does the study involve?
In Burkina Faso, school are randomly allocated to one of two groups: no intervention (control) or the whole package (nutrition, WASH and school garden). In Nepal, schools are randomly allocated to one of four groups: no intervention (control) or school gardens (but no nutrition and WASH) or nutrition and WASH (but no school gardens) or the whole package (nutrition, WASH and school garden).
What are the possible benefits and risks of participating?
The possible benefits for the participants will occur at several levels:
1. At the level of schools, the study will increase the knowledge of teachers and children about WASH and nutrition interlinkage for better health.
2. At the level of households and communities, the study will increase alike the knowledge of mothers and children care takers about WASH and nutrition interlinkage for better health.
3. After the baseline surveys, participants will benefit from free drug administration for parasitic infections and specific treatment on anaemia (both) or any other clinical signs that may indicate a nutritional deficiency (e.g. Bitots spot, dry and infected cornea, dermatitis in Nepal).
4. Furthermore, after the surveys, the project will design and implement locally appropriate complementary nutrition and health interventions based on the results of the baseline study with the support of the school principals, teachers, the research team, and implementing partners.
To prevent any risks, participants are informed in detail about the study processes at each step and either oral or written consent is collected both from the respondent and the legal representative.
Where is the study run from?
Selected schools in Burkina Faso and Nepal
When is the study starting and how long is it expected to run for?
February 2014 to December 2016
Who is funding the study?
Swiss Agency for Development and Cooperation (SDC)

Complementary nutrition, WASH and school garden interventions in Burkina Faso and Nepal: measuring school children’s nutritional and health status at baseline and follow-up over a 1-year period.
We assume that integrated nutrition, WASH and school gardening interventions have an effect on school children’s dietary and hygienic knowledge, awareness and practices, eventually improving their nutritional and health status. Therefore, the following hypotheses are made: complementary nutrition, WASH and school garden interventions will have a positive impact on targeted school children’s nutrition and health knowledge, attitudes, practices and finally, improve their nutritional status (anthropometrics, haemoglobin) and health (parasitic infections, clinical examination in Nepal only).
Additional hypothesis tested in Nepal only:
1. The combination of only nutrition and WASH interventions has fewer/equal effects on targeted school children’s nutrition and health status than the combined nutrition, WASH, health and school vegetable garden intervention package.
2. The school gardens interventions only (without combinations or complementary interventions) have fewer/equal effects on targeted school children’s nutrition and health status than (i) the combination of only nutrition and WASH interventions; and (ii) the combined nutrition, WASH, health and school vegetable garden intervention package.

Communicable diseases (soil-transmitted helminths, protozoa, Schistosomiasis) and Nutrition
With the results of the baseline assessments in Burkina Faso and Nepal, appropriate complementary nutrition-and health-sensitive interventions are designed to improve the nutritional and health status of school children. These complementary interventions include the improvement of water and sanitary environments in schools, communities and households, biannual deworming of school-aged children; and especially school, community and household sensitisation on improved hygiene and dietary behaviours.
Two studies are conducted in 8 schools of Burkina Faso and in 16 schools of Nepal. The schools are randomly assigned to groups as follows:
Randomised intervention trial with two study arms and 2 schools per arm in Burkina Faso:
1. One arm without any intervention, the control schools;
2. One arm with the whole intervention package, means school garden, nutrition and WASH interventions.
Randomised intervention trial with four study arms and 4 schools per arm in Nepal:
1. One arm with school gardens but no nutrition and WASH interventions;
2. One arm with nutrition and WASH interventions but no school gardens;
3. One arm with school gardens nutrition and WASH interventions;
4. One arm without school gardens, nutrition and WASH interventions (control schools)
Primary outcome measure
1. In Burkina Faso, the primary outcome measure is the differences in the prevalence of parasitic infections between school children of the intervention and control groups.
2. In Nepal, the primary outcome measure is the difference in the nutritional and health status (especially focused on malnutrition) between school children of the intervention and control groups.
Secondary outcome measures
1. Assessing school children’s nutritional status (BMI for age, height for age), dietary diversity, haemoglobin level, and their nutrition- and WASH- related knowledge and practices.
2. Analysing water, sanitation, and hygiene conditions at the level of selected schools, households and communities at the baseline and end-line of the study.
3. Assessing household socio-economic determinants, food security situation and nutrition- and health-related KAP
In Burkina Faso, the follow-up study will take place in February 2016 to evaluate possible changes in primary and secondary outcomes. In Nepal, the follow-up study will take place in May 2016 to evaluate the possible changes in primary and secondary outcomes.

1. First, clinical and questionnaire based results of the cross-sectional baseline assessment are intended to be published between September and December 2015.
2. Publication and dissemination of the results of the follow-up study is planned for June-September 2016.
In Nepal the baseline laboratory, clinical, anthropometry and questionnaire based knowledge, attitude and practice related findings of the cross sectional assessments are intended to be published by November 2015. The publication and dissemination of the results after interventions is planned for September-December 2016.
