Social capital and self‐reported oral health at baseline of the brazilian longitudinal study of aging

Objectives This cross‐sectional study aimed to estimate the association between the structural and cognitive dimensions of social capital and self‐reported oral health. Methods This study conducted individual assessments of 9,365 individuals aged 50 years or older from Brazil. Four individual variables based on structural and cognitive dimensions of social capital were assessed. We used hierarchical Poisson regression models to estimate the prevalence ratio of self‐reported oral health with individual structural and cognitive social capital variables adjusted for associated factors. Results Cognitive social capital was associated with self‐reported oral health. Individuals who reported lack of neighbourhood trust and not having friends presented 14% (RP: 1.14; 95% CI: 1.07‐1.21) and 9% (RP: 1.09; 95% CI: 1.01‐1.19), respectively, higher prevalence of poor self‐reported oral health, relative to those who trust in their neighbourhood and reported having friends. Conclusion The cognitive dimension of social capital may be linked with self‐reported oral health. Therefore, social capital can be stimulated in the context of social policies as its encouragement can be an efficient tool for improving individuals’ health and, consequently, the oral health of the older people.
