Prevalence of anemia and associated risk factors among pregnant women attending antenatal care in Bangladesh: a cross-sectional study

Background: Anemia has created attention worldwide because of its adverse effects on the mother and the fetus during pregnancy. A large body of evidence has shown that pregnant women are the most vulnerable group to anemia. Objectives: This study aims to determine the prevalence of anemia, and associated risk factors, among pregnant women attending antenatal care (ANC) at government and private hospitals in Bangladesh. Methods: This cross-sectional study included 424 pregnant women, who visited hospitals for ANC from January to July 2019. We used a simple random sampling technique to select study subjects. Data were collected using a structured questionnaire and participant's current medical record cards. SPSS software was used for analyzing data. Results: The prevalence of anemia was 62.5% and significantly (P < 0.001) higher in the subjects attending ANC in government hospitals (68.7%) than in private (55.0%) hospitals. The prevalence of the severity of anemia was 28.3% mild, 36.9% moderate, and 3.40% severe in government hospitals while in private hospitals was 14.7% mild, 39.8% moderate, and 0.5% severe anemia. Anemia was significantly associated with maternal age 20-25 years [adjusted odds ratio (AOR) = 1.9] and 26-30 years (AOR = 2.37), monthly family income (300-500) US$ (AOR = 2.76), and ANC in government hospitals (AOR = 2.02), the parity [multiparous (AOR = 1.92)], gravidity [multigravid (AOR = 1.63)], contraception [no contraception (AOR = 2.50), and iron supplement [no iron supplement (AOR = 0.64). Conclusions: The result suggests that pregnant women should receive routine ANC and recognize iron supplementation during pregnancy. Finally, the results of this study are particularly relevant for pregnant women who are receiving ANC.
