Association between migration and oral health-related quality of life: results from a nationally representative online survey

Abstract

Abstract Purpose To analyze the link between individuals with and without migration background and oral health-related quality of life (also stratified by sex). Methods Data in this cross-sectional study were taken from a nationally representative survey (n = 3075, August/September 2021). The Oral Health Impact Profile (OHIP-G5) was used to measure oral health-related quality of life. Two-part models were calculated, adjusting for various covariates. Results Individuals with migration background had lower oral health-related quality of life (total sample, Cohen’s d = − 0.30; in men, d =− 0.44; in women, d =− 0.22). Two-part models also revealed that the migration background was associated with a higher likelihood of OHIP-G5 scores of one or higher (total sample and in both sexes). Moreover, migration background was positively associated with the extent of oral health-related quality of life (conditional on OHIP-G5 scores of one or higher; total sample and in men). Furthermore, regressions showed that migration background was associated with lower oral health-related quality of life (total sample and in both sexes). Conclusions Our study emphasized the link between having a migration background and lower oral health-related quality of life among both women and men. Maintaining oral health among individuals with a migration background is a key challenge. Culturally and socially sensitive actions should provide easy accessible oral health information and preventive measures in order to lower access barriers in dental care for individuals with migration background.
