An effectiveness study has been embedded within the pilot programme to assess the effect of the MNP plus IYCF intervention package in relation to the programme's goals and outcomes under programmatic conditions within the target population. There will be two distinct groups invited to participate in the effectiveness component of the pilot, both in the district of Mbala. One will serve as a control group, and as such will not receive MNP. Both the treatment group and control groups will receive IYCF and early child development (ECD) training, deworming tablets (Mebendazole) and insecticide-treated nets, while the treatment group will additionally receive MNP.
