Dietary vitamin A intake and its major food sources among rural pregnant women of South-West Bangladesh

Abstract

The study aimed to estimate the dietary intake of vitamin A and its major food sources among rural pregnant women from the southwest region of Bangladesh. A multi-stage random cluster sampling method was used to select the respondents (N = 1012). A semi-structured questionnaire was used to collect the data, and statistical analysis was conducted using IBM SPSS 20.0. The mean age of the respondents was 23.27 ± 5.23 years, and the majority were in their second (48%) and third trimester (49%). The mean dietary intake of vitamin A was 392 ± 566 μg Retinol Activity Equivalent (RAE)/day (51% of Recommended Dietary Allowance). The contribution of β-carotene (plant source) and retinol (animal source) in vitamin A intake was about 60% and 40%, respectively. The major β-carotene contributing food groups were vegetables (dark and light) and tubers, and food items were colocasia, potato, beans, brinjal, and ripe tomatoes. On the other hand, the major retinol-contributing food groups were fish, eggs, and milk, and food items were small fish, Rui (carp) fish, and cow’s milk. It was also observed that the consumption of food items from β-carotene and retinol-contributing food groups did not differ significantly among the three groups of respondents, but the variations in the amount of the different food items consumed were significant. Dietary vitamin A intake is low among pregnant women in the South-West region of Bangladesh. Hence, they are at a greater risk of adverse materno-fetal health outcomes associated with vitamin A deficiency.
