Other Household Survey [hh/oth]
This randomized control trial evaluation consists of three rounds of data collection: a baseline survey during the second quarter of 2014, a midline survey in 2015, and an endline survey in 2016. Interventions started in September 2014 in all the treatment groups. The baseline survey can be accessed through the World Bank Microdata Library using the following link: https://microdata.worldbank.org/index.php/catalog/3877. The midline survey can also be accessed through the Microdata Library using the following link: https://microdata.worldbank.org/index.php/catalog/4199. The endline survey is documented here.
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.
Trial Registration: Current Controlled Trials ISRCTN14393738. Registered June 23, 2015.

Sampling
Our sampling frame is the universe of community nutrition project sites in the five 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.
Our sample of interest is the cohort of children (and their households) sampled at baseline and followed longitudinally at midline and at endline surveys. 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 had 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.
Survey instrument
The following questionnaires were used for data collection:
The Household Questionnaire includes detailed sections on demographics, housing/water and sanitation, education, household expenditures, food security, and shocks. The household questionnaire was administered to the household head, or in his/her absence to the most informed household member. Data on food security status was collected using the Household Food Insecurity Access Scale (HFIAS) developed by the USAID-funded Food and Nutrition Technical Assistance II project (FANTA) and on dietary diversity using the Household Dietary Diversity Score (HDDS).
The Female and Child Questionnaire were administered to all primary caregivers of the target children. At baseline, all primary caregivers were asked about fertility. Mothers were administered sections on knowledge about nutrition and child development, as well as a module on child appetite and responsive feeding. A child questionnaire was administered to all primary caregivers include delivery information, breastfeeding history and status, timing introduction of complementary feeding, morbidity, and a 24 hour dietary recall. Child weight, height, and mid upper-arm circumference were measured at baseline in duplicate using techniques described for the WHO Multicenter Growth Reference Study. Child development was assessed using The Ages and Stages Questionnaire Inventory (ASQI), which is a comprehensive self-report maternal assessment of child development. ASQ-I is a continuous version of child development and progress as opposed to the more widely used ASQ-3 screening tool. The subscales measure skills in Communication, Gross Motor, Fine Motor, Personal-Social and Problem-Solving domains. In addition, pregnant women and primary caregivers were also administered a module on depression, using the Center for Epidemiological Studies Depression Scale (CESD) and administered a test on receptive vocabulary, using the Peabody Picture Vocabulary Test (PPVT) already adapted for Madagascar.
The Community Health Worker Questionnaire was administered to both the community nutrition worker (ACN) and the added community nutrition worker (ACDN, if already identified at baseline). The questionnaire includes demographics and socio-economic information about the community worker (education, occupation, household assets) and a Motivation Scale. The community workers were administered the same test of receptive vocabulary, using the Peabody Picture Vocabulary Test (PPVT) administered to the primary caregiver. In addition, the questionnaire has specific sections about the site characteristics, the characteristics and composition of a volunteer support group, the referral to a health center and the training received.
A Community Questionnaire was administered to a group of informed leaders about the size and population of the village (Fokontany), accessibility and availability of local infrastructure, the presence of associations in the village, the occurrence of weather shocks and production shocks.
The questionnaires are provided in French and Malagasy and are available for download.

Local non-governmental organizations (NGOs) were responsible for providing program supervision. To minimize contamination of intervention by supervisors, these NGOs were randomly sampled with one site per NGO supervisor, and stratified by region, whenever possible.
Data collection was conducted using Survey Solutions (https://mysurvey.solutions/en/).
The unit of randomization is the project site or community. Within each region/stratum, 25 project sites were randomly assigned to the four treatment arms and one comparison arm. The intervention groups are as follows:
T0: Program as currently designed (“status quo comparison”) - community based nutrition program with growth monitoring and education. Our counterfactual policy scenario is not a "no program" group. T0 had the existing program, which includes nutrition messages, growth monitoring, cooking demonstrations and brief counseling (a short, 5-min, discussion with the mother immediately after her child is weighed).
T1: Intensive counseling - the existing community-based program was enhanced with intense training with material and protocols for counseling and referral when indicated. An added community nutrition worker was selected in intervention communities to carry out home visits for nutrition counseling, with higher frequency of visits for the younger children (monthly visits for the 0-8 month-olds) and decreasing frequency for older children. All pregnant women and children 0-2 enrolled in the community program were eligible for receiving the nutrition counseling. A particular emphasis of the enhanced training was given to communication and listening skills, and to problem solving strategies for food security.
T2: Intensive counseling + lipid based supplementation to children 6-18 months - delivered in a monthly ration providing 20 g per day of supplement (under the brand name “Kalina Be”) per child in the household. All children 6-18 months enrolled in the community program were eligible for receiving the supplement.
T3: Intensive counseling + lipid based supplementation to children 6-18 months + pregnant and lactating women - delivered in a monthly ration providing 20 g per day (“Kalina Be”) of supplement per child plus 40 g per day (“KalinaReny”) for mothers in the household. All pregnant women and children 6-18 months enrolled in the community program were eligible for receiving the nutrition supplement.
T4: Intensive counseling based on infant and young child feeding practices + early childhood stimulation and development for children 6-18 months - delivered via twice monthly one-on-one home visits with the added community health worker, who provides intensive feedback regarding early stimulation for the target child. For the purpose of the pilot, the 30 children randomly drawn to be participating in the baseline survey were eligible for the ECD home visits (in addition to the nutrition intensive counseling component). The eligible children and mothers within the project site who were not selected for the ECD home visits were provided a community based play activity at the project site for a few days a week (ludotheque).
The randomized control trial evaluation consists of three 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.
