This report presents the results of the quantitative impact evaluation of the WINNN programme, three years since the baseline study. Using a quasi-experimental approach combined with community-level qualitative research, the study evaluates the impact of the WINNN programme as a whole on nutritional behaviours, nutritional status and provision of nutrition services. Data was collected from a panel of 3,229 households in 2013 and then again in 2016 in three treatment and three control Local Government Areas in each of the five states. To factor out pre-existing differences between the treatment and control groups, a difference-in-difference approach is utilised.

While no impact of the programme is found on anthropometric indicators, the evaluation finds positive impact on a number of intermediate outcomes such as IYCF knowledge and practice, awareness of and attendance at Maternal Neonatal and Child Health Weeks events as well as coverage of Vitamin A supplementation. However, there are significant differences in impact across states as roll-out was not uniform in terms of timelines and modalities. Using evaluation findings, a number of important lessons and recommendations are outlined for the WINNN programme and for the design of nutrition programmes in Nigeria and in similar contexts.

This is a summary of the report. Volume 1 presents the main findings of the evaluation followed by lessons learnt from the evaluation. Detailed methodology, additional background information and results, and quality assessment reports can be found in Volume 2 which serves as a technical and methodological companion to the main report.
