The randomized control trial evaluation consists of two rounds of data collection: a baseline survey during the second quarter of 2014, a midline in 2015 and an endline in 2016. Interventions started in September 2014 in all the treatment groups. At endline, we will compare the value added of each layer with its added cost, and as a consequence, assess the cost-effectiveness of alternative modes for service delivery.
The MAHAY study uses a multi-arm randomized-controlled trial (RCT) to test the cost-effectiveness of combined interventions to address chronic malnutrition and poor child development. The arms of the trial are: (T0) existing community-based nutrition program with monthly growth monitoring and nutritional/hygiene education; (T1) is T0 + home visits for intensive nutrition counseling within a behavior change framework; (T2) is T1 + lipid-based supplementation (LNS) for children 6-18 months old; (T3) is T2 + LNS supplementation of pregnant/lactating women; and (T4) is T1 + intensive home visiting program to support child development.

Our sampling frame is the universe of community nutrition project sites in the target regions of the program. From this universe of project communities, we drew a sample of communities that was randomly assigned to five groups. The comparison group for our study is the program as currently designed (as opposed to no program in most of the evaluation literature). In the four randomized arms, we have sequentially added increasing levels of intensity and complexity to the current intervention, starting with the lowest cost option and incrementally adding layers of intensity (and cost) to test the value added of each layer in terms of their ability to reduce stunting/growth faltering and promote child development.
Deviations from the Sample Design
Our sample of interest is the cohort of children (and their households) sampled at baseline and followed longitudinally at midline and at endline survey. The sample was drawn from the census of children enrolled in the community-based intervention in December 2013 and updated in May 2014 in preparation for the baseline fieldwork. A sample of 3,738 households with either pregnant women or with children aged 0-11 months old was selected at baseline. At midline and endline tracking protocols were put in place with the objective to minimize attrition and preserve a sample that reflected the target population of children in the program site.
The following tracking criteria were followed:
if the pregnant woman had a miscarriage or died, or if the target child had died, the household was considered as lost
if the target child had temporarily moved within the catchment area of the program sites, the child should be located and interviewed
If the target child has moved outside the catchment area (and therefore not eligible to receive the services), the household would be replaced with a household randomly chosen from within the same age group
if the target child returned to the original household after their temporary migration at endline, both the original household and its replacement household at midline were interviewed at endline.
The following questionnaires were used for data collection

The questionnaires were administered in French and they are provided in pdf for download.
