Associations between maternal health literacy and prenatal micronutrient intake in Hungarian women

Abstract Background Adequate level of health literacy (HL) is an important factor in pregnancy. Low HL may increase the risk of maternal and fetal complications (e.g., gestational diabetes mellitus, low birth weight). This study aimed to measure the levels of maternal HL and its associations with the consumption of folic acid (FoA), vitamin D (VD), and omega-3 fatty acids (FAs) during pregnancy in Hungarian women. Methods The questionnaire-based study was conducted at the Department of Obstetrics and Gynecology, University of Szeged among women who gave birth between June and September 2023 (N = 294). Sociodemographic, lifestyle, conception and pregnancy related questions were asked. HL was measured by the Maternal Health Literacy Inventory in Pregnancy (MHELIP) questionnaire (after the Hungarian adaptation); it contains 48 items representing four subscales (maternal health knowledge, search for maternal health information, assessment of maternal health information, and maternal health decision making and behavior). Data analysis was performed by SPSS 29.0. (Ethical permission: 5351) Results The mean age of women was 31.53 +-4.75 years. During pregnancy 84.5% of women consumed FoA, 61.8% VD and 41.8% omega-3 FAs. The total mean score of MHELIP on a scale 0-100 was 78.93 (95%CI: 77.77-80.08); the score of “search for maternal health information” subscale was the lowest [57.68 (95%CI: 56.20-59.16)], and the score of “maternal health decision making and behavior” was the highest [86.75 (95%CI: 85.62-87.87)]. Omega-3 FAs and VD consumption was significantly higher in women with higher total and subscales mean scores (except “search for maternal health information”), while FoA consumption was significant in case of “assessment of maternal health information”. (The results are preliminary.) Conclusions The association between micronutrient consumption and HL supports that using this tool during pregnancy the mothers who needs more support and health information can be identified. Key messages • The Maternal Health Literacy Inventory in Pregnancy questionnaire is a reliable tool for measuring health literacy in Hungarian pregnant women. • Maternal health literacy plays an important role in the healthier lifestyle, including prenatal vitamin/micronutrient consumption.
