Adherence and associated factors to iron and folic acid supplementation among pregnant women attending antenatal care in public hospitals of Dire Dawa, Eastern Ethiopia

INTRODUCTION: Worldwide, 41.8% of pregnant women have anemia. Nationally, only 0.4% of pregnant women take the recommended 180-day iron supplement for more than 90 days. This study aimed to determine adherence to iron and folic acid supplements and factors affecting it among pregnant women attending antenatal care in public hospitals of Dire Dawa City, eastern Ethiopia. METHODS: An institutional-based cross-sectional study design was conducted from 1 January 2019 to 30 June 2019. In all, 416 pregnant women were selected using a systematic random sampling method. Data were collected using an interviewer-administered questionnaire and analyzed using SPSS version 22.00. Bivariate and multivariable logistic regression with a 95% confidence interval was done, and variables at a p<0.05 were considered statistically significant to the outcome variable. RESULTS: The study revealed that 71.8% of pregnant women have adhered to iron/folic acid supplements. Pregnant women who had ≥4 antenatal care visits (AOR=3.15; 95% CI: 1.16–9.05), got advice about iron/folic acid supplementation (AOR=3.12; 95% CI: 1.15–5.29), good knowledge about iron/folic acid supplementation (AOR=3.56; 95% CI: 1.42–8.54), good knowledge about anemia (AOR=5.22; 95% CI: 2.06–8.33), and currently anemic (AOR=2.58; 95% CI: 2.38–9.61) were significantly associated with adherence of iron/folic acid supplementation. CONCLUSIONS: The adherence of iron/folic acid supplementation of pregnant women was good. Getting advice about iron/folic acid supplementation, ≥4 antenatal care visits, having good knowledge about iron/folic acid supplementation and anemia, and currently anemic, were factors associated with adherence to iron/folic acid supplementation.
