Benefits of a Household WASH Package to Community-based Management of Acute Malnutrition (CMAM) Program, Chad

The Action Contre la Faim (ACF) nutrition project in Kanem started in 2008, and now is set up in 35 health facilities divided across 2 health districts: Mao and Mondo. The management of severe acute malnutrition is done in both OTP (Outpatient Therapeutic Programme) and in TFC (Therapeutic Feeding Center). Between the treatment of SAM in OTPs and TFCs, and the number of curative consultations, the total number of beneficiaries is expected to be 45,065 in 2014 (without double counting).

Clear evidence exists that some Water, Sanitation and Hygiene (WASH) interventions can successfully prevent diarrhea. For instance, interventions aiming at improving water quality at household level or at promoting hand washing with soap do reduce significantly diarrhea incidence. Estimations showed that WASH interventions have a small but measurable benefit on length growth, but not on weight or weight/height. Yet, to our knowledge, no impact of WASH interventions has been assessed, neither during nutritional rehabilitation where children are particularly vulnerable to infections, nor after discharge where immune recovery is still incomplete.

In the context of nutritional rehabilitation of SAM (Severe Acute Malnutrition), the investigators hypothesize that improving water quality and hygiene-related care practices at household level would decrease incidence of WASH-related infections, such as diarrhea, nematode and environmental enteropathy. As such, it would improve weight gain, decrease relapses after successful discharge, and overall, could decrease over time the incidence of acute malnutrition in the community.

The proposed WASH intervention will be added to already existing nutritional activities and it will include: i/ Household water treatment and hygiene kit (water container, water disinfection consumables, soap, cup, hygiene promotion leaflet) provided at beginning of SAM treatment; ii/ sessions of Hygiene promotion provided weekly at health center level iii/ Household visits and hygiene sessions made during the treatment; // group discussion on hygiene and care practices made with mother at community level after successful discharge.
