Effect of Health Education on the Knowledge of Pregnant Women on Iron and Folic Acid Supplements: A Stepped Wedge Cluster Randomized Trial

Abstract

Iron deficiency poses a significant public health challenge during pregnancy. However, optimal uptake of antenatal micronutrients is hampered by lack of knowledge. We investigated the effect of health education on knowledge of women regarding antenatal Iron and Folic Acid Supplements (IFAS). In a 9-month trial, antenatal care clinics received a maternal IFAS awareness package, which included education for both health workers and pregnant women and health Information Education and Communication (IEC) materials. The study found that IFAS knowledge improved from 44.8% to 81.1%, a 36-percentage point increase. To enhance IFAS knowledge, hence uptake, the study recommends targeted health education emphasizing IFAS benefits, management of IFAS side effects, along with providing standardized information materials to the clinics.
