Cigarette smoking remains a significant public health problem that causes many deaths worldwide. We used the Tobacco Use Supplement to the Current Population Study data to analyze how smoking behavior changed among different U.S. subpopulations from 1992 to 2019. We employed joinpoint regression analysis, the Cochran-Armitage test, and the Jonckheere-Terpstra test to detect changes in smoking trends and daily cigarette consumption. We found that the overall smoking prevalence declined from 24.46 to 11.46%, with the largest decline in the 18–24 age group. However, we also found persistent disparities in smoking rates by gender, urbanization, and ethnicity. Separated individuals and those with lower education had higher smoking rates than others throughout the study period. Unemployed people also had very high smoking prevalences consistently. Daily cigarette consumption decreased over the study period as well. Our study shows that while there has been progress in reducing cigarette use, there are still significant gaps among some sociodemographic groups that need more attention and intervention.

吸烟仍然是一个重大的公共卫生问题，导致全世界许多人死亡。我们使用当前人口研究的烟草使用补充数据来分析 1992 年至 2019 年美国不同亚人群吸烟行为的变化。我们采用连接点回归分析、Cochran-Armitage 检验和 Jonckheere-Terpstra 检验来检测吸烟变化趋势和每日香烟消费量。我们发现总体吸烟率从 24.46% 下降至 11.46%，其中 18-24 岁年龄段下降幅度最大。然而，我们还发现，不同性别、城市化程度和种族之间的吸烟率存在持续差异。在整个研究期间，分居的人和受教育程度较低的人的吸烟率高于其他人。失业人员的吸烟率也一直很高。在研究期间，每日香烟消费量也有所减少。我们的研究表明，虽然在减少香烟使用方面取得了进展，但一些社会人口群体之间仍然存在显着差距，需要更多关注和干预。
