Vitamin A deficiency is one of the most serious health problems in developing countries. This study aims to explore the comparative figure of vitamin A knowledge, household consumption frequency of vitamin A-rich foods, and association of socio-demographic factors with knowledge and consumption in four residential areas in Tangail district, Bangladesh. Methods: This study used a population-based cross-sectional design with 400 study participants selected using purposive sampling technique. Knowledge and consumption frequency were assessed by a structured questionnaire along with food frequency table. Data were analysed using descriptive statistics. Results: Only 33.5% participants had primary vitamin A knowledge, where most from urban (48.5%) and semi-urban (30.6%) areas had comparatively higher knowledge than those from rural (11.2%) and slum (9.7%) areas. Specific knowledge level was also poorer in rural and slum areas than urban and semi-urban areas. Most of the participants received knowledge through commercial advertisements (65.7%). Household consumption frequency of vitamin A-rich foods (plant and animal) was comparatively lower in rural and slum areas than in urban and semi-urban areas. Different socio-demographic factors (place of residence, education and household income) significantly influenced participant’s vitamin A knowledge and household consumption of vitamin A-rich foods (p<0.05). Conclusion: In general, the study population lacked knowledge regarding the importance of vitamin A. Consumption frequency of vitamin A-rich foods was still poorer in slum and rural areas than in urban and semi-urban areas.
