Introduction: Iron-folic acid supplementation is one of the key interventions provided during antenatal care (ANC) services to reduce iron deficiency, maternal anemia, low birthweight and other pregnancy-related complications responsible for maternal and neonatal mortality. However, use of iron-folic acid supplements and adherence with recommended dosage in Nigeria is low. The purpose of this cross-sectional study was to examine factors associated with iron-folic acid supplements use among pregnant women in Karu local government area (LGA), Nasarawa, Nigeria. Methods: Questionnaires were administered in face-to-face interviews with 64 pregnant women (18 – 49 years old) and 19 healthcare providers in selected public primary health facilities across Karu LGA, Nasarawa State. Using the theory of planned behavior, pregnant women’s intention to use iron-folic acid supplements during pregnancy was predicted. In addition, factors associated with duration of use were also examined. Data was analyzed using STATA 15.0. Results: Subjective norm (p = 0.02) and perceived behavioral control (p = 0.04) significantly predicted the intention to use iron-folic acid supplements during pregnancy. However, attitude did not have a predictive influence on intention. A one unit increase in the number of antenatal care visits made, significantly increased the likelihood of taking iron-folic acid supplement for three months or more (p=0.000). Discussion: Perceived behavioral control was the strongest predictor of intention to use iron-folic acid supplements followed by subjective norm. Antenatal care attendance are very critical to the use of iron-folic acid supplements and should be promoted.
