Objectives: To investigate the prevalence of poor self-reported oral health and to identify socio-demographic, socio-economic and cultural-related risk factors associated with poor oral health among Sámi in Sweden.
Methods: A Sámi sample frame was constructed drawing from three pre-existing registers. All identified persons aged 18–84 were invited to participate in the study during February–May 2021. Among the 9249 invitations, 3779 answered the survey. The frequencies of the independent variables in terms of socio-economic, socio-demographic and cultural-related factors as well as the outcome, self-reported oral health, were calculated first. Prevalence ratios (PRs) and their 95% confidence interval (95% CI) were estimated to assess the relationship between the independent variables and the outcome.
Results: Overall, 32.5% of the participants reported a poor oral health with a higher prevalence among men compared to women. Among the socio-demographic factors, being old (PR: 1.99; 95% CI: 1.59–2.51), unmarried (PR: 1.17; 95% CI: 1.03–1.33) and divorced or widow-er (PR: 1.27; 95% CI: 1.09–1.46) were statistically associated to poor self-reported oral health. Among the socio-economic factors, a low education level (PR: 1.56; 95% CI: 1.29–1.89), belonging to the poorest quintile (PR: 1.63; 95% CI: 1.35–1.96), and experiencing difficulties to make ends meet several times during the last 12 months (PR: 1.74; 95% CI: 1.51–1.99) were statistically significant related to poor oral health.
Conclusions: The self-reported oral health among Sámi in Sweden appears to be worse than that of the general Swedish population. Several socio-economic and socio-demographic factors were found to be strongly associated with poor self-reported oral health. Targeted interventions addressing these social determinants are needed to reduce inequalities in oral health among the Sámi population.
