Influence of sociodemographic factors and Family Health Strategy coverage on oral health promotion procedures: an analysis of Brazilian municipalities in 2019

BACKGROUND: The aim of the study was to investigate associations between sociodemographic factors and municipal Family Health Strategy (FHS) coverage and oral health promotion (OHP) procedures in Brazil. MATERIAL AND METHODS: Data were obtained using public information systems and by direct request to the Ministry of Health. Clinical and collective OHP procedures performed in 2019 were analyzed, and sociodemographic covariates were associated with FHS coverage (population covered by FHS teams [FHST] and oral health teams [OHT]). Negative binomial regression models associated outcomes with covariates and estimated the prevalence ratio (PR) and confidence intervals (95%CI). RESULTS: A total of 4,913 municipalities were included. Municipalities with low-income inequality (PR=1.04, 95%CI 1.01 to 1.08), high illiteracy rate (RP=1.06, 95%CI 1.00 to 1.13), and population size of 10,001 to 50,000 inhabitants (PR=1.07, 95%CI 1.02 to 1.12) and 50,001 to 100,000 (PR=1.21, 95%CI 1.12 to 1.30) showed a higher frequency of clinical procedures. In contrast, a low frequency of clinical procedures was associated with reduced vulnerability to poverty (PR=0.83, 95%CI 0.78 to 0.89) and low OHT coverage (PR=0.39, 95%CI 0.33 to 0.45). Regarding collective procedures, the final model showed associations between low frequency and reduced income inequality (PR=0.91, 95%CI 0.87 to 0.95), low per capita income (PR=0.84, 95%CI 0.81 to 0.88), and low (PR=0.53, 95%CI 0.35 to 0.80) and medium Human Development Index (PR=0.79, 95%CI 0.71 to 87). CONCLUSIONS: Clinical and collective OHP procedures were associated with sociodemographic conditions and OHT coverage in the FHS.
