A total of 400 partici- pants were randomly selected. Data were collected through face to face interviews. Only 15.0% and 3.5% participants had knowledge about vitamin A fortifi ed edible oils and rice respectively. Precisely vitamin A fortifi ed edible oils knowledge level was found inferior in rural (11.7%) and slum (0%) than urban (48.3%) and semi-urban (40.0%) participants. Knowledge about vitamin A fortifi ed rice was found higher in urban (78.6%) than rural (14.3%) and slum (0%) participants. Most of the participants received knowledge through advertisements (Nϭ45 and Nϭ12 for fortifi ed oils and rice respectively). Maximum partici- pants (62.3%) did not consume vitamin A fortifi ed edible oils and consumption rate in rural (11.8%) and slum (10.2%) areas were poorer than urban (53.5%) and semi-urban (24.4%) areas. Consumption rate of vitamin A fortifi ed rice was found nil in all the study areas. Lack of knowledge about vitamin A fortifi ed rice and oils accounted solely for poor consumption. Knowledge level about vitamin A fortifi ed edible oils and rice and consumption rate were found statistically signifi cantly (pϽ0.05) with participant’s place of residences, education level and monthly income. Finally, this study indicates that the overall knowledge level and consumption rate of vitamin A fortifi ed edible oils and rice is poor especially in rural and slum populations in Tangail Sadar Upazila.
