1986年第四季度,美国疾病控制中心(CDC)吸烟与健康办公室组织了一个全国性的成人吸烟状况调查,旨在研究美国成年人对烟草的认识、态度及其吸烟状况。用概率抽样抽取13,031名17岁及以上成人,进行电话询问调查。与过去40年来进行的其它全国性吸烟状况调查相比,此次调查结果表明,当今美国成人中的吸烟率是有记录以来最低的(表1),男性为29.5%(95%可信限为28.4～30.6),女性为23.8%(95%可信限22.7～24.9),男女合计为26.5%(95%可信限25.8～27.3)。估计成人中有24.6%曾经吸过烟(但目前已不吸),其中男性为30.4%,女性为19.3%。黑人吸烟率为28.4%(95%可信限25.0～31.8),白人为26.4%(95%可信限25.5～27.2)。
In the fourth quarter of 1986, the CDC’s Office of Smoking and Health organized a nationwide survey on adult smoking to study the perceptions, attitudes and smoking patterns among American adults about tobacco use. A total of 13,031 adults aged 17 and over were sampled by probability sampling to investigate by phone. In contrast to other national smoking status surveys conducted over the past 40 years, the results of this survey show that the prevalence of smoking in today’s U.S. adults is the lowest ever recorded (Table 1) and 29.5% for men (95% confidence limit 28.4-30.6), 23.8% for women (95% confidence interval 22.7-24.9), and 26.5% for men and women (95% confidence interval 25.8-27.3). It is estimated that 24.6% of adults smoke (but are not smoking now), 30.4% of them men and 19.3% of women. Black smoker rates were 28.4% (95% confidence interval 25.0-31.8) and whites 26.4% (95% confidence interval 25.5-27.2).
