Trends in smoking prevalence and attributable mortality in China, 1991-2011.

ABSTRACT: China is the largest producer of tobacco worldwide. We assessed secular trends in prevalence of smoking, average cigarettes per day, mean age of initiation, and mortality attributable to smoking among the Chinese population between 1991 and 2011.Data came from the China Health and Nutrition Survey, conducted eight times between 1991 and 2011. A total of 83,447 participants aged 15years or older were included in this study. Trends in smoking were stratified by sex, age, and region (urban vs. rural).In 2011, 311 millions individuals were current smokers in China, with 295 million men and 16 million women, respectively. Between 1991 and 2011, the prevalence of current smoking decreased from 60.6% to 51.6% in men, and from 4.0% to 2.9% in women. However, during this period, the average number of cigarettes smoked per day per smoker increased from 15.0 to 16.5 in males, and from 8.5 to 12.4 in females. Further, age of smoking initiation decreased from 21.9 to 21.4years in men and from 31.4 to 28.4years in women. In 2011, 16.5% of all deaths in men and 1.7% in women were due to smoking. Between 1991 and 2011, the total number of deaths caused by smoking increased from 800,000 to 900,000.During the past 20years, a slight decrease in smoking prevalence was observed in the Chinese population. However, cigarette smoking remains a major cause of death in China, especially in men.

Project description:ImportancePresident Biden recently prioritized the fight against smoking as key to reducing cancer mortality.ObjectiveTo assess trends in smoking and illuminate the association between smoking and reducing deaths due to cancer.Design, setting, and participantsThis cross-sectional study used responses to National Health Interview Surveys from January 1, 2011, to December 31, 2022, to characterize trends in current smoking for key sociodemographic groups among US adults.ExposuresAge (18-24, 25-39, 40-64, and ≥65 years), family income (<200%, 200%-399%, and ≥400% of the federal poverty level [FPL]), educational level (less than high school, high school degree or General Educational Development, some college, and college degree or above), and race and ethnicity (Black, Hispanic, White, and other).Main outcomes and measuresWeighted current smoking prevalence with 95% CIs by analysis group from 2011 to 2022. Average annual percentage change (AAPC) in smoking prevalence by analysis group is calculated using Joinpoint regression.ResultsData from 353 555 adults surveyed by the National Health Interview Surveys from 2011 to 2022 were included (12.6% Black, 15.0% Hispanic, 65.2% White, and 7.3% other race or ethnicity). Overall, smoking prevalence decreased among adults aged 18 to 24 years from 19.2% (95% CI, 17.5%-20.9%) in 2011 to 4.9% (95% CI, 3.7%-6.0%) in 2022 at an AAPC of -11.3% (95% CI, -13.2% to -9.4%), while it remained roughly constant among adults 65 years or older at 8.7% (95% CI, 7.9%-9.5%) in 2011 and 9.4% (95% CI, 8.7%-10.2%) in 2022 (AAPC, -0.1% [95% CI, -0.8% to 0.7%]). Among adults 65 years or older, smoking prevalence increased from 13.0% (95% CI, 11.2%-14.7%) in 2011 to 15.8% (95% CI, 14.1%-17.6%) for those with income less than 200% FPL (AAPC, 1.1% [95% CI, 0.1%-2.1%]) and remained roughly constant with no significant change for those of higher income. Similar age patterns are seen across educational level and racial and ethnic groups.Conclusions and relevanceThis cross-sectional study found that smoking prevalence decreased from 2011 to 2022 in all age groups except adults 65 years or older, with faster decreases among younger than older adults. These findings suggest that the greatest gains in terms of reducing smoking-attributable morbidity and mortality could be achieved by focusing on individuals with low socioeconomic status, as this population has the highest smoking rates and the worst health prospects.
