A record based operational research was conducted to explore the effect of targeted food supplementation of National Nutritional Program on pregnancy weight-gain. Records of chronic energy deficient mothers who delivered their baby between 1st January and 31st December, 2008 in the study areas were reviewed. The study included 439 samples from Kapasia sub-district, a National Nutritional Program intervention area and 126 samples from Savar subdistrict, as control area. In the National Nutritional Program area 211 (48%) of the chronic energy deficient mothers were enrolled for supplementation and only 34 (8%) of them completed the full course. Samples of Kapasia and Savar were significantly different in their socio-demographic status.
