Prevalence of past-year dental visit among US adults, 1999-2010: comparison of trends and estimates between the Behavioral Risk Factor Surveillance System and three national surveys.

Abstract

To compare estimated prevalence of past-year dental visit (PPYDV) among US adults aged ≥18 years from the Behavioral Risk Factor Surveillance System (BRFSS) to estimates from the Medical Expenditure Panel Survey (MEPS), National Health Interview Survey (NHIS), and National Health and Nutrition Examination Survey (NHANES). We estimated PPYDV adjusted for covariates (age, race/ethnicity, education level, poverty status, edentulism) using BRFSS, MEPS, and NHIS 1999-2010, and NHANES 1999-2004. We tested trend in overall PPYDV for BRFSS, MEPS, and NHIS from 1999-2010. For 2002 and 2010, we calculated absolute differences (AD) and 95% confidence intervals (CI) in PPYDV between BRFSS and each of the other surveys overall and among subpopulations defined by covariates. We pooled NHANES 1999-2004 data for comparison with BRFSS 2002. From 1999 to 2010, BRFSS (68.5% vs. 67.5%), MEPS (43.5% vs. 39.7%), and NHIS (63.3% vs. 59.7%) showed small but significant decreases in overall PPYDV. In 2002, estimates for overall PPYDV were highest for BRFSS (70.0%) and lowest for MEPS (43.9%) with estimates for NHIS (61.5%) and NHANES (1999-2004: 58.1%) in between; the largest AD (26.2%, 95% CI: 25.0%-27.3%) was between BRFSS and MEPS. ADs were consistent in 2002 and 2010, overall and by covariates, except among edentate persons, where PPYDV estimates from BRFSS and NHIS were similar. Estimates of PPYDV from BRFSS were notably higher than estimates from MEPS, NHIS, or NHANES except among the edentate. Trends in PPYDV over time, however, were consistent across all surveys.
