We tested whether across the 50 U.S. States, smoking prevalence was associated with smoking behavior among smokers.
We used published data on smoking prevalence, cigarette consumption, and quit attempts by State from the Behavioral Risk Factor Surveillance System (BRFSS) for 1993, 1996, and 1999, and published data on the distribution of smokers by stage of change in each State from the Current Population Survey (CPS). Data were weighted for the population size in each State.
For 1993, we found no statistically significant association between smoking prevalence and stages of change. For 1996 and 1999, across the 50 States, each additional percentage point in smoking prevalence was associated with, respectively, 0.62% and 1.19% more smokers in the "precontemplation" stage, that is, smokers not intending to quit smoking (both P < 0.01), with, respectively, 0.82% and 1.21% more "heavy" smokers who smoked 21-40 cigarettes per day (both P </= 0.001), and with, respectively, 1.12% and 0.81% fewer daily smokers who quit smoking for 1+ days in the previous year (both P </= 0.04).
Across the 50 States, a higher prevalence of cigarette smoking was associated with a lower motivation to quit smoking, fewer quit attempts, and higher cigarette consumption among smokers.
我们测试了在美国50个州中，吸烟率是否与吸烟者的吸烟行为相关。
我们使用了行为风险因素监测系统（BRFSS）公布的1993年、1996年和1999年各州的吸烟率、香烟消费量和戒烟尝试数据，以及当前人口调查（CPS）公布的各州吸烟者按行为改变阶段分布的数据。数据按各州人口规模进行加权。
1993年，我们发现吸烟率与行为改变阶段之间无统计学显著关联。1996年和1999年，在50个州中，吸烟率每增加一个百分点，分别与处于“未考虑戒烟”阶段（即不打算戒烟的吸烟者）的吸烟者增加0.62%和1.19%相关（P均<0.01），与每天吸21 - 40支烟的“重度”吸烟者分别增加0.82%和1.21%相关（P均≤0.001），与上一年戒烟1天及以上的每日吸烟者分别减少1.12%和0.81%相关（P均≤0.04）。
在50个州中，较高的吸烟率与吸烟者较低的戒烟动机、较少的戒烟尝试以及较高的香烟消费量相关。
