One of the national health objectives for 2010 is to reduce the prevalence of cigarette smoking among adults to £ 12% (objective 27.la). To assess progress toward this objective, the Centers for Disease Control and Prevention (CDC) analyzed self-reported data from the 2000 National Health Interview Survey (NHIS) sample Adult Core questionnaire and Cancer Control module. This report summarizes the findings of this analysis, which indicate that, in 2000, approximately 23.3% of adults were current smokers compared with 25.0% in 1993, reflecting a modest but statistically significant decrease in prevalence among US adults.
In 2000, an estimated 70% of smokers said they wanted to quit, and 41% had tried to quit during the preceding year; however, marked differences in successful quitting were observed among demographic groups. A comprehensive approach to cessation that comprises economic, clinical, regulatory, and educational strategies is required to further reduce the prevalence of smoking in the United States.
Representative Sample Surveyed
The 2000 NHIS Adult Core questionnaire was administered by personal interview to a nationally representative sample (n = 32,374) of the US noninstitutionalized civilian population aged ³ 18 years; the survey response rate was 72.1%. Respondents were asked, "Have you smoked ³ l00 cigarettes in your entire life?" and "Do you now smoke cigarettes every day, some days, or not at all?"
"Ever smokers" were those who reported having smoked ³ 100 cigarettes during their lifetime. Current smokers were ever smokers who reported smoking every day or some days. Former smokers were ever smokers who currently did not smoke. Interest in quitting smoking completely and attempts to quit were determined by asking current smokers, "Would you like to completely quit smoking cigarettes?" and "During the past 12 months, have you stopped smoking for 1 day or longer because you were trying to stop smoking?" Data were adjusted for nonresponses and weighted to provide national estimates. Confidence intervals were calculated using survey data analysis (SUDAAN) software.
In 2000, an estimated 46.5 million adults (23.3%) were current smokers. Overall, 19.1% of adults were everyday smokers and 4.1% were some day smokers. The prevalence of smoking was higher among men (25.7%) than women (21.0%, see Table 1). Among racial/ethnic groups, Asians (14.4%), and Hispanics (18.6%) had the lowest prevalence of adult cigarette use; American Indians/Alaska Natives had the highest prevalence (36.0%).
