Abstract

Objective Assess whether there is an interactive effect between oral health literacy and acculturation on dental care use for Hispanic adults. Methods Self-identifying Hispanic adults participated in this observational study (N = 338). Oral health literacy (low vs. high) was measured using the Comprehensive Measure of Oral Health Knowledge (CMOHK). Acculturation (low vs. high) was measured using the Short Acculturation Scale for Hispanics (SASH) and operationalized a second way by the language in which the survey was completed (English or Spanish). The outcome was dental care use in the past year (yes/no). Confounder-adjusted modified Poisson regression models were run to generate risk ratios (RR) and to test the hypothesis that participants with high oral health literacy and high acculturation would be more likely to have used dental care in the past year than participants with low oral health literacy and low acculturation. Results About 65% of participants used dental care in the past year. The final models failed to show that participants with high oral health literacy and high acculturation were more likely to have used dental care than other participants. However, in the language proxy interaction model, participants with high oral health literacy and low acculturation were significantly more likely to have used dental care than participants with low oral health literacy and low acculturation. Conclusion There may be an interaction between oral health literacy and acculturation when modeling dental care use for Hispanic adults that should be further explored.
