Abstract

We assessed characteristics and correlates of recent successful cessation (quitting smoking for 6 months or longer within the past year) among US adult cigarette smokers aged 18 years or older. Estimates came from the July 2018 fielding of the 2018–2019 Tobacco Use Supplement to the Current Population Survey (N = 26,759). In 2018, 7.1% of adult smokers reported recent successful cessation. Recent successful cessation varied by certain demographic characteristics, noncigarette tobacco product use, smoke-free home rules, and receipt of advice to quit from a medical doctor. To help more smokers quit, public health practitioners can ensure that evidence-based tobacco control interventions, including barrier-free access to evidence-based cessation treatments, are reaching all tobacco users, especially those who face greater barriers to quitting.

Objective

Increasing smoking cessation reduces smoking-related disease, death, and economic costs (1,2). Understanding the factors that contribute to successful cessation can inform public health strategies to help smokers quit successfully (2). By using nationally representative data from the Tobacco Use Supplement to the Current Population Survey (TUS-CPS), we assessed characteristics and correlates of adult cigarette smokers who quit smoking for 6 months or longer in the past year.

Methods

Data came from the July 2018 fielding (the first of 3 data collections) of the 2018–2019 TUS-CPS, a cross-sectional, household-based survey of noninstitutionalized US adults aged 18 years or older in the 50 US states and the District of Columbia (3). TUS is administered every 3 to 4 years as part of CPS, a monthly survey conducted by the US Census Bureau for the US Bureau of Labor Statistics (4). In July 2018, 26,759 adults completed the TUS-CPS interview as self-respondents (mean self-response rate, 57.7%).

Current smokers were defined as adults who had smoked at least 100 cigarettes during their lifetime and currently smoked “every day” or “some days.” Former smokers were adults who had smoked at least 100 cigarettes during their lifetime but currently did not smoke at all. Recent successful smoking cessation was defined as former smokers who quit smoking cigarettes within the past year and remained quit for 6 months or more. Recent successful cessation was assessed among former smokers who quit within the past year and current smokers who smoked for at least 2 years (5).

The prevalence of recent successful cessation (quitting smoking for 6 months or longer within the past year) was examined overall and by sex, race/ethnicity, age, education, occupation, annual household income, metropolitan status, US region, disability/limitation status, current e-cigarette use, current use of other noncigarette tobacco products, and past-year menthol cigarette smoking. Cessation correlates included receipt of advice to quit from a medical doctor, smoke-free home rules, comprehensive smoke-free workplace policy, and use of a cessation treatment/method in the past 12 months. Data were weighted to account for the complex survey design and to yield nationally representative estimates with 95% confidence intervals. Statistical analyses were performed by using SAS-callable SUDAAN version 11.0.1 (Research Triangle Institute). Chi-squared tests were used to determine significant (P < .05) differences.

Results

In 2018, 7.1% of adult smokers reported recent successful cessation (Table 1). By demographic characteristics, no significant differences in the prevalence of recent successful cessation were observed by sex, race/ethnicity, annual household income, metropolitan status, or US region. By age, the prevalence of recent successful cessation of at least 6 months generally decreased as age increased, falling from 13.7% among adults aged 18 to 24 years to 5.0% among adults aged 45 to 64 years. Moreover, prevalence generally increased with greater educational attainment, ranging from 4.4% among adults with less than a high school education to 8.7% among respondents who had at least some college education. By occupation, recent successful cessation of at least 6 months ranged from 4.5% (construction workers) to 8.7% (both white-collar workers and workers in the service industry). Adults without a disability had a significantly higher prevalence of recent successful cessation of at least 6 months (7.5%) than adults with a disability (5.3%). Results also varied by respondents’ use of noncigarette tobacco products. Specifically, current exclusive e-cigarette users had a higher prevalence of recent successful cigarette smoking cessation (15.1%) than adults who currently used other noncigarette tobacco products (3.3%) and adults who did not currently use any other noncigarette tobacco products (6.6%). Prevalence did not differ significantly between adults who usually smoked menthol cigarettes in the past year and adults who did not.

By cessation correlates, recent successful cessation was higher among adult smokers who were advised to quit smoking by a medical doctor in the past year (4.9%) than among adults who were not (3.2%) and among adults who reported having smoke-free home rules (9.8%) than among adults who did not (2.4%) (Table 2). Recent successful cessation did not differ significantly by the presence of a comprehensive smoke-free workplace policy or by cessation methods used in the past year, which ranged from 10.4% for adults who used nicotine replacement therapy alone to 15.1% for adults who did not use any cessation method.

Discussion

We found that in 2018, 7.1% of US adult smokers reported quitting smoking for 6 months or longer. This finding aligns with an estimate of 7.5% based on 2018 National Health Interview Survey data (6). Furthermore, a subset of adults who successfully quit smoking reported current use of noncigarette tobacco products and thus continued to be exposed to the harmful effects of tobacco.

Prior data demonstrate that smokers use various evidence-based and nonevidence-based methods when trying to quit (7). In our study, no single cessation method or combination of methods assessed was significantly associated with recent successful cessation; however, small cell sizes limited the ability to obtain several estimates. Currently, 7 medications approved by the Food and Drug Administration (FDA) and 3 types of counseling are scientifically proven to be safe and effective in helping adult smokers quit (2,8,9).

Our findings indicate that 15% of smokers who were current exclusive users of e-cigarettes reported recent successful smoking cessation. The role of e-cigarettes in helping smokers transition completely away from cigarette smoking warrants further research; the US Surgeon General’s report concluded evidence is inadequate to conclude that e-cigarettes, in general, increase smoking cessation (2), and the FDA has not approved e-cigarettes as safe and effective smoking cessation aids (2,10).

This study has limitations. First, smoking status and cessation behaviors were based on self-report. Second, these data are cross-sectional and cannot be used to assess temporality or causality; therefore, the association between certain indicators, including current e-cigarette use and recent successful cessation, should be interpreted with caution (11). Third, the study did not assess other factors (eg, health insurance status) that could contribute to differences in recent successful cessation among adult smokers.

In conclusion, in 2018, about 1 in 14 US adult smokers reported recent successful smoking cessation. Some groups had less success, including certain demographic groups, and some groups had greater success, including exclusive e-cigarette users, people with smoke-free home rules, and people who received advice to quit from a medical doctor. To help more smokers quit, public health practitioners can ensure that evidence-based tobacco control interventions, including barrier-free access to evidence-based cessation treatments, are reaching populations that face greater barriers to successfully quitting smoking (1,2). Coordinated local, state, and national efforts can accelerate progress toward increasing smoking cessation and reducing tobacco-related disease and death (1,2).
