Prenatal care health promotion education is an important strategy for reducing perinatal health disparities. The purposes of this study were to (a) identify differences between the health promotion content women wanted to discuss and the content women reported discussing and (b) determine whether ethnicity was related to health promotion content. A cross-sectional study used face-to-face interviews to obtain data about 159 Mexican American and African American pregnant women's prenatal experience. Women wanted more health promotion content than they discussed. Despite wanting information about more health promotion topics than African American women. Mexican American women discussed fewer topics. Ethnicity, number of topics women wanted to discuss, whether a woman had a primary provider, and type of prenatal provider model were also related to content.
