Abstract

The aim of the present study was to assess oral health literacy (OHL) in pregnant women and its association with social determinants and knowledge regarding eating habits and oral hygiene in infants. This cross-sectional study assessed 175 pregnant women in a hospital in southern Brazil. Socioeconomic and demographic data were obtained using a questionnaire, and OHL was determined by the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30). Eating habits and oral hygiene knowledge were assessed by statements on a 3-point Likert scale. The data were analyzed using Spearman correlations and the Mann–Whitney U test (α = 0.05). The mean (SD) age was 26.2 (6.17) years. Most of the participants had up to 8 years of education (60.0 %) and belonged to socioeconomic class “C” or lower (56.0 %). The mean (SD) score on the BREALD-30 was 22.4 (4.66). A positive correlation was found between BREALD-30 scores and knowledge (r s  = 0.370, p < 0.001), income (r s  = 0.374, p < 0.001), and the age at which infants first consumed sugar in their diets (r s  = 0.370, p < 0.001). A negative correlation was found between BREALD-30 scores and domicile agglomeration (r s  = −0.237, p = 0.020). BREALD-30 scores were higher among pregnant women who had more than 8 years of education (p < 0.001), who belonged to higher socioeconomic classes (p < 0.001), and who were employed (p = 0.025). A significant correlation was found between OHL and knowledge. Lower social determinants were associated with lower OHL. Oral health literacy should be considered in health education practices to facilitate adherence to health recommendations in pregnant women.
