The first stage of the study involves working with the procurement and program staff to ensure that oil and CSB will be available at the same time in sufficient quantities and can be distributed together. We will work with program staff and outside consultants (if needed) to develop locally acceptable recipes for CSB plus oil. A sample of communities with MCHN programs will be chosen, and the intervention (consistent provision of CSB with oil, teaching of recipes using CSB with oil, appropriate behavioral support) implemented. Tufts and locally contracted researchers will interview program staff involved in procurement and supply chain management as well as program staff, and beneficiaries, to assess the feasibility and acceptability of the provision of CSB with oil, and identify barriers and problems. This stage is expected to take six months.
