This study compared trends in adult cigarette smoking prevalence in California and the remainder of the United States between 1978 and 1994.
We used data from National Health Interview Surveys and Behavioral Risk Factor Surveillance System surveys to compare trends in smoking prevalence among persons 18 years and older.
In both California and the remainder of the United States, the estimated annual rate of decline in adult smoking prevalence accelerated significantly from 1985 to 1990: to -1.22 percentage points per year (95% confidence interval [CI] = -1.51, -0.93) in California and to -0.93 percentage points per year (95% CI = -1.13, -0.73) in the remainder of the nation. The rate of decline slowed significantly from 1990 to 1994: to -0.39 percentage points per year (95% CI = -0.76, -0.03) in California and to -0.05 percentage points per year (95% CI = -0.34, 0.24) in the remainder of the United States.
The presence of an aggressive tobacco control intervention has supported a significant decline in adult smoking prevalence in California from 1985 to 1990 and a slower but still significant decline from 1990 to 1994, a period in which there was no significant decline in the remainder of the nation. To restore nationwide progress in reducing smoking prevalence, other states should consider similar interventions.

    • "These studies also have used NHIS data to explore numerous questions on the prevalence of cigarette smoking, such as how many people smoke cigarettes [4-23], how much they smoke, and tobacco products they use in addition to cigarettes [4,16,24-28]. Questions also have addressed whether smoking prevalence increased or decreased over specified times [15,27,29-31] and examined smoking patterns by sociodemographic factors, such as gender and/or age [32-36], race/ethnicity [37-44], socioeconomic status [9,15,45-49], education [50], and geographic region [23,31,40,51]. In addition, studies have addressed specific populations of interest, such as adolescents [24,35,52-54], adolescents and young adults [55], women [17,45], older adults [10], veterans [56], active military personnel [57], medical professionals [58-60], and other occupational groups [8,45,61].

    ABSTRACT: The National Health Interview Survey (NHIS) is a continuous, nationwide, household interview survey of the civilian noninstitutionalized population of the United States. This annual survey is conducted by the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. Since 1965, the survey and its supplements have provided data on issues related to the use of cigarettes and other tobacco products. This paper describes the survey, provides an overview of peer-reviewed and government-issued research that uses tobacco-related data from the NHIS, and suggests additional areas for exploration and directions for future research. We performed literature searches using the PubMed database, selecting articles from 1966 to 2008. Study selection. Inclusion criteria were relevancy to tobacco research and primary use of NHIS data; 117 articles met these criteria. Data extraction and synthesis. Tobacco-related data from the NHIS have been used to analyze smoking prevalence and trends; attitudes, knowledge, and beliefs; initiation; cessation and advice to quit; health care practices; health consequences; secondhand smoke exposure; and use of smokeless tobacco. To date, use of these data has had broad application; however, great potential still exists for additional use. NHIS data provide information that can be useful to both practitioners and researchers. It is important to explore new and creative ways to best use these data and to address the full range of salient tobacco-related topics. Doing so will better inform future tobacco control research and programs.

    • "Findings from the current study are consistent with a relative lack of change in smoking behavior patterns. Based on three separate surveys [18] [20], daily smokers, for the most part, have not markedly changed their stage of change and the percentage of daily smokers who were interested in modifying their smoking behavior remained static throughout the de- cade. Taken together, this information should be of concern to the public health community. "

    ABSTRACT: Population-based national estimates of stage of change among daily smokers are unknown. This study described the proportion of U.S. daily smokers, 18 and older, by stage of change. Selected sociodemographic characteristics were delineated. Cross-sectional data were collected via telephone or face-to-face interview in daily smokers who responded to the Current Population Survey in 1992-1993 (n = 39,706), 1995-1996 (n = 34,865), or 1998-1999 (n = 30,153). Main outcomes included stage of change: (1) Precontemplation-not interested in quitting smoking in next 6 months; (2) Contemplation-interested in quitting smoking in next 6 months but not next 30 days; (3) Preparation-interested in quitting smoking in next 30 days and stopped at least 1 day during past year. During 1992-1993, 59.1% of respondents were precontemplators, 33.2% contemplators, and 7.7% in preparation stage. This distribution was similar in subsequent surveys (1995-1996; 1998-1999). Gender differences were not apparent. Whites were more likely to be precontemplators. As education and income increased, the percentage in precontemplation decreased. Rural residents were more likely in precontemplation and less frequently in preparation. Among daily smokers, little movement in stage of change was apparent in the United States during the 1990s. Tobacco control efforts must receive high priority to address these static patterns.
