In 2016, a follow up study will be conducted to determine the sustained impacts on IYCF practices, expansion of operations and promoted practices into new areas, and diffusion of IYCF information, two years after the termination of external project support. Because achievements related to service delivery and outcomes are intended to be sustained in the intervention areas and even expanded to other areas where BRAC's Essential Health Care program operates, including the comparison areas, this study aims to examine elements in both the original intervention and comparison areas.
