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.
比较行为危险因素监测系统（BRFSS）中年龄≥18岁的美国成年人过去一年牙科就诊（PPYDV）的估计患病率与医疗支出小组调查（MEPS）、国家健康访谈调查（NHIS）和国家健康与营养检查调查（NHANES）的估计值。
我们使用BRFSS、MEPS以及1999 - 2010年的NHIS和1999 - 2004年的NHANES，对协变量（年龄、种族/族裔、教育水平、贫困状况、无牙情况）进行调整后估计PPYDV。我们测试了1999 - 2010年BRFSS、MEPS和NHIS总体PPYDV的趋势。对于2002年和2010年，我们计算了BRFSS与其他各项调查总体以及按协变量定义的亚人群之间PPYDV的绝对差异（AD）和95%置信区间（CI）。我们汇总了1999 - 2004年的NHANES数据以与2002年的BRFSS进行比较。
1999年至2010年，BRFSS（68.5%对67.5%）、MEPS（43.5%对39.7%）和NHIS（63.3%对59.7%）总体PPYDV均呈现虽小但显著的下降。2002年，BRFSS的总体PPYDV估计值最高（70.0%），MEPS最低（43.9%），NHIS（61.5%）和NHANES（1999 - 2004年：58.1%）介于两者之间；BRFSS与MEPS之间的AD最大（26.2%，95% CI：25.0% - 27.3%）。2002年和2010年，总体及按协变量划分的AD均保持一致，但无牙人群除外，BRFSS和NHIS的PPYDV估计值相似。
除无牙人群外，BRFSS的PPYDV估计值显著高于MEPS、NHIS或NHANES。然而，所有调查中PPYDV随时间的趋势是一致的。
