The study evaluates the impact of a multi-sectoral intervention (water, sanitation, and hygiene; training on climate smart activities; care groups for mothers; market gardens) on the prevalence of acute malnutrition as the primary outcome using a randomized intervention trial between 2012-2017 with four points of data collection (2012, 2014, 2015, and 2017).

Concern Worldwide has developed a model of intervention called Community Resilience to Acute Malnutrition (CRAM). This model is based on the need for (a) the introduction of longer-term programming to build community resilience to shocks, while recognising that there may be a need for humanitarian intervention, and (b) a multi-sectoral package of activities given experience in programming from other settings. The goal of the study is to rigorously test the impact of the model and associated activities on community resilience to shocks in the Goz Beida area of Chad. Where community resilience is proxied by the primary outcome variable: acute malnutrition.

In order to answer this question, 69 villages had been randomized to either receive the full multi-sectoral program or not. In each village, approximately 20 households were surveyed (randomly selected from a household list from a previous emergency distribution) for a total of 1420 households. Those households were then surveyed in November/December 2012 (prior to the intervention), and again a the same time period in 2014, 2015, and 2017.

Data was collected on household demographics, livelihoods, child health, and nutrition, including child (6-59 months) anthropometry.

Inclusion Criteria:

• child is from household with B, C, or D wealth ranking (wealth ranking is from A-D with A being the highest wealth and D being the lowest wealth)
• child is between the ages of 6-59 months
• child is present in the selected household at the time of the survey

Exclusion Criteria:

• child has a skin disorder
