[Oral health literacy of persons with migration background-first results of the MuMi study].

Background: First investigations indicate a migration background of residents in Germany as a discrete risk factor for poor oral health. A lower level of oral health literacy among people with a migration background is considered a reason worthy of being investigated.
Aim: This article presents results on oral health literacy and oral health gained from the MuMi study (promoting oral health and oral health literacy of people with a migration background).
Methods: The oral health and oral health literacy as well as the sociodemographics of patients with and without migration background were examined in 40 dental surgeries in Hamburg, Germany. Associations between migrant status, oral health, and oral health literacy were analyzed with logistic regressions. Potential confounders were gradually integrated into the multivariate analyses.
Results: Patients with and without a migration background differed significantly in oral health literacy and clinical parameters of oral health (approximal plaque index and degree of caries restoration). The logistic regression analysis revealed highly significant associations between migration background, oral health literacy, and oral hygiene, while also accounting for education and socioeconomic status.
Discussion: Migration background constitutes a discrete risk factor for lower oral health and oral health literacy for these relevant population groups. This fact needs stronger reflection in further research and political decision-making in order to promote equality of oral health opportunities.
