Do Socioeconomic Inequalities, Residential Setting and Social Networks Predict Different Patterns of Dental Services Utilisation?

Abstract

Objective: To estimate the probability of dental services utilisation according to demographics, socioeconomic characteristics, and social networks of Brazilians aged 15 years and above.

Methods: The study used data from the 2019 Brazilian National Health Survey, a household-based representative nationwide survey. Individual interviews collected information on time interval since the last dental appointment, residential setting, sex, race/skin colour, years of school completed with approval, family income and social networks. Predicted probabilities and 95% confidence intervals (CIs) of time since last dental visit were estimated using a multinomial logistic regression model. Estimates were obtained using the post-estimation commands of Stata MP, version 17.0, considering the complex sampling design and sampling weights.

Results: Prevalence of last dental visit in the last 12 months was 48.4% (47.8%-49.0%). The projected scenarios showed a significant effect of sex, socioeconomic characteristics and social networks on dental services utilisation. The worst scenario was observed for male individuals living in rural areas, with lower schooling, lower income and lower social networks. In this group, the prevalence of dental visit in the previous 12 months was 14.7% (13.1%-16.2%) and 23.1% (19.3%-26.9%) reported never having had a dental visit. Individuals with low social networks exhibited lower dental services utilisation than those with high social networks, across both better and worse socioeconomic status scenarios.

Conclusion: Individuals aged 15 years and above with poor socioeconomic status, living in rural areas, and those with low social networks had lower use of dental services.
