The baseline survey is a key part of the project evalu- ation strategy aimed at assessing the impact of integrat- ing OFSP on the health and nutrition status of mothers and children less than two years of age. The survey was conducted in the catchment area of eight healthcare fa- cilities serving a population of 362,151 individuals in the larger Bungoma and Busia districts of Western Province, Kenya [17]. The health facilities were selected based on the population served and the number of service pro- viders, to facilitate the operational strategy of the in- tervention and to prevent leakage during OFSP project implementation.
