A Mixed Methods Comparison of Oral Hygiene Behaviors by Gender Among Mexican-Origin Young Adults in California.

Objective: This mixed methods study explores gender differences in, and reasons for, toothbrushing and flossing among Mexican-origin adults. Methods: Interviews and surveys about oral hygiene behaviors were collected from 72 adults (ages 21-40) living on the California-Mexico border. Interviews were audio-recorded, transcribed in their original language (English/Spanish), then coded. Survey responses were linked to coded transcripts in Dedoose. Qualitative reports were thematically analyzed for each behavior, stratified into four groups by gender and whether or not participants met American Dental Association (ADA) weekly guidelines (brushing ≥ 14/week; flossing ≥ 7/week). Self-reported weekly frequencies of brushing and flossing were collected continuously, and then dichotomized as meeting guidelines or not. Kruskal-Wallis and chi-square tests assessed differences in hygiene behavior frequency by gender. Negative binomial and logistic regressions were performed, accounting for socio-demographic characteristics. Results: Overall, 76% and 40% of adults met ADA guidelines for brushing and flossing, respectively. There were no differences in meeting ADA guidelines by gender. When brushing was examined continuously, women brushed 1.24 (1.05-1.47; Conclusions: Integrating quantitative and qualitative data obtained from Mexican-origin adults identified few differences in both oral hygiene behaviors and the factors that influence their enactment.
