ABSTRACT eHealth literacy plays a crucial role during pregnancy, as maternal health behavior can influence health outcomes for both mother and child. This study assessed the impact of eHealth literacy on maternal-fetal health outcomes through a cross-sectional analysis of 1,265 pregnant women admitted to a tertiary maternity hospital in Turkey between April and July 2022. Data on sociodemographic information, obstetric variables, birth outcomes, Internet usage, and eHealth Literacy Scale (eHEALS) were collected. Kolmogorov-Smirnov, Mann – Whitney U, Kruskal-Wallis, and Spearman correlation were used for data analysis. The median age of women was 28 years, and the mean gestational age was 38.6 weeks. Median eHealth literacy score was 21 (range:8-40). Pregnant women who had planned pregnancies, received spousal support, attended 9–12 antenatal care visits, received vaccinations, adhered to iron and folic acid supplementation, engaged in regular physical activity, and maintained regular sleep patterns exhibited higher eHealth scores (all p < .001). eHEALS scores were higher in women who experienced normal vaginal deliveries (p < .001), while lower eHEALS scores were noted in those with comorbidities (p = .001). The study suggested that higher eHealth literacy among pregnant women was associated with improved health-promoting behaviors, more favorable health perceptions, increased utilization of health services, and better maternal and fetal outcomes.
