RESUMEN
PURPOSE: This study assessed the impact of a lecture on children's oral health knowledge of pregnant women from vulnerable African American (AA) and Hispanic of Mexican origin (HM) populations utilizing the same urban community health center prenatal education program. METHODS: Participants heard one 45-minute lecture in English or Spanish on children's oral health, and completed a survey (English or Spanish) before and after the lecture. RESULTS: Seven sessions provided 60 participants: (a) 30 AA; and (b) 30 HM. These two groups differed on: (1) educational attainment; (2) preferred language; (3) country of origin; and (4) baseline scores. They were similar in: (1) age; (2) frequency of first mothers; and (3) final scores. Oral health knowledge significantly rose from baseline to the end of the lecture (ANOVA, P < .001). Educational attainment was associated with HM baseline scores (P = .04), whereas age was associated with AA final scores (P = .01). CONCLUSIONS: An oral health lecture within a prenatal program improved oral health knowledge for African American and Hispanic of Mexican origin pregnant women, though associated factors varied between the two groups. Further study is needed to explore long-term knowledge retention and effect on the future babies' oral health.
