Heterogeneity in periodontitis prevalence in the Hispanic Community Health Study/Study of Latinos

PURPOSE: To examine acculturation and established risk factors in explaining variation in periodontitis prevalence among Hispanic/Latino subgroups. METHODS: Participants were 12,730 dentate adults aged 18–74 years recruited into the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) from four U.S. field centers between 2008 and 2011. A standardized periodontal assessment measured probing pocket depth and gingival recession at six sites per tooth for up to 28 teeth. Periodontitis was defined according to the CDC/AAP case classifications developed for population surveillance. Covariates included acculturation indicators and established periodontitis risk factors. Survey estimation procedures took account of the complex sampling design. Adjusted multivariate binomial regression estimated prevalence ratios (PR) and 95% confidence limits (95% CL). RESULTS: Unadjusted prevalence of moderate/severe periodontitis was 38.5% and ranged from 24.7% among Dominicans to 52.1% among Cubans. Adjusted prevalence ratios for subgroups relative to Dominicans were: 1.34 (95% CL: 1.13, 1.58) among South Americans; 1.37 (95% CL: 1.17, 1.61) among Puerto Ricans; 1.43 (95% CL: 1.25, 1.64) among Mexicans; 1.53 (95% CL: 1.32, 1.76) among Cubans; and 1.55 (95% CL: 1.35, 1.78) among Central Americans. CONCLUSION: Heterogeneity in prevalence of moderate/severe periodontitis among Hispanic/Latino subpopulations was not explained by acculturation or periodontitis risk factors
