This study examined whether there are systematic differences between the Behavioral Risk Factor Surveillance System (BRFSS) and the Current Population Survey (CPS) for state cigarette smoking prevalence estimates.
BRFSS telephone survey estimates were compared with estimates from the US Census CPS tobacco-use supplements (the CPS sample frame includes persons in households without telephones). Weighted overall and sex- and race-specific BRFSS and CPS state estimates of adults smoking were analyzed for 1985, 1989, and 1992/1993.
Overall estimates of smoking prevalence from the BRFSS were slightly lower than estimates from CPS (median difference: -2.0 percentage points in 1985, -0.7 in 1989, and -1.9 in 1992/1993; P < .05 for all comparisons), but there was variation among states. Differences between BRFSS and CPS estimates were larger among men than among women and larger among Blacks than among Hispanics or Whites; for most states, these differences were not significant.
The BRFSS generally provides state estimates of smoking prevalence similar to those obtained from CPS, and these are appropriate for ongoing state surveillance of smoking prevalence.
本研究探讨了行为危险因素监测系统（BRFSS）与当前人口调查（CPS）在各州吸烟流行率估计方面是否存在系统性差异。
将BRFSS电话调查估计值与美国人口普查CPS烟草使用补充调查的估计值进行比较（CPS样本框架包括没有电话的家庭中的人员）。分析了1985年、1989年和1992/1993年BRFSS和CPS对成年人吸烟情况的加权总体估计值以及按性别和种族分类的估计值。
BRFSS的吸烟流行率总体估计值略低于CPS的估计值（中位数差异：1985年为-2.0个百分点，1989年为-0.7个百分点，1992/1993年为-1.9个百分点；所有比较的P<0.05），但各州之间存在差异。BRFSS和CPS估计值之间的差异在男性中比在女性中更大，在黑人中比在西班牙裔或白人中更大；对于大多数州来说，这些差异并不显著。
BRFSS通常提供的各州吸烟流行率估计值与从CPS获得的估计值相似，这些估计值适用于对吸烟流行率进行持续的州级监测。
