Cohort Analysis of Immigrant Rhetoric on Timely and Regular Access of Prenatal Care

OBJECTIVE:To assess whether recent anti-immigration rhetoric is significantly associated with inadequate prenatal care. METHODS:This was a population-based cohort study (2011–2017). In their native language, patients were consented and queried regarding country of origin and time in the United States. Additional variables were collected or abstracted from the medical record, including documentation and timing of prenatal visits. Based on relevance and prevalence during the study period, publicly available Google search trends were mined for the terms “Make America Great Again,” “Mexico Wall,” and “Deportation” by geographic region. The time of first deviation from the mode Google search popularity value for each term was ascertained (mode inflection date). Perinatal data was averaged over 15 days moving windows, and the Adequacy of Prenatal Care Utilization Index was used to categorically define inadequate prenatal care by validated standards. RESULTS:Twenty-four thousand nine hundred thirty-three deliveries occurred during the study period. A mode inflection date was extrapolated from Google trend analytics and used to define the period before change in trends use pre (before rhetoric) and post (after rhetoric). Coincident to the rhetoric change, there was a significant increase in days until the first prenatal visit, fewer prenatal visits, and a decreased trend of mean hemoglobin nadir among U.S. non-native Hispanic women (P
