A Prospective Evaluation of Health Literacy Levels of Pregnant Women in Antenatal Classes: Impact on Delivery Outcomes in Nulliparous and Multiparous Women.

Backgrounds/Objectives: Modern technology and educational activities, such as antenatal classes (ACs), increase patient informedness in medicine and improve collaboration between physicians and patients. The present study aimed to evaluate and compare the impact of maternal health literacy (HL) on delivery outcomes between nulliparous and multiparous women who attended antenatal classes. Methods: This prospective study recruited 281 pregnant women who regularly attended ACs, but only 188 who gave birth at our academic tertiary hospital were included in the final analysis. Socio-demographic characteristics, peripartum data (cervical dilatation at the time of admission to the hospital, duration of labor, and mode of delivery), and obstetric interventions (cesarean section (C/S) rate and rate of instrumental vaginal birth and episiotomy) were recorded, and the level of HL was assessed using the European Health Literacy Survey Questionnaire (HLS-EU-Q16). HL levels did not significantly affect peripartum and postpartum outcomes. Results: The study results showed that HL levels did not impact labor duration and newborn Apgar scores (p > 0.05). Patient education levels and employment status affected the peripartum duration of labor (p = 0.048 and p = 0.001, respectively). There were no differences in the HL total score and subscale scores (p > 0.05) between nulliparous and multiparous patients, and the rate of primary C/S was similar in both groups. Conclusions: HL levels did not impact delivery (peripartum) outcomes in pregnant women who attended antenatal classes. However, the primary C/S rate was similar between the nulliparous and multiparous groups, which may indicate that antenatal education services can correct the negative impact of low HL levels on the primary C/S rate.
