Sociodemographic and Temporal Differences in Menthol Cigarette Use Among US Adults Who Smoke, 1999-2018.

Introduction: Monitoring menthol cigarette use allows for identification of potential health disparities. We examined sociodemographic and temporal differences in menthol cigarette use among US adults who smoke.

Methods: We analyzed data from the 1999-2018 National Health and Nutrition Examination Survey for adults aged 20 years or older who smoke (N = 11,431) using binary logistic regression.

Results: Among US adults who smoke, 28.8% used menthol cigarettes. After adjusting for age, sex, race and ethnicity, education, income-to-poverty ratio, and health status, the prevalence of menthol use among adults who smoke increased on average by 3.8% (95% CI, 2.7%-4.9%) annually. Non-Hispanic Black adults had the highest average prevalence of menthol cigarette use, 73.0% (95% CI, 70.9%-75.2%), and Mexican American adults had higher average annual increase in menthol cigarette use, 7.1% (95% CI, 4.0%-10.3%). Adults with fair or poor health status had a 4.3% annual increase in menthol cigarette use (95% CI, 2.5%-6.1%). The adjusted prevalence ratios of menthol cigarette use were 1.61 (95% CI, 1.39-1.83) for adults aged 20-29 years compared with those aged 65 years or older, 1.41 (95% CI, 1.32-1.49) for female adults compared with male adults, and 1.17 (95% CI, 1.07-1.27) for high school graduates or higher compared with those with no high school diploma.

Conclusion: Non-Hispanic Black adults who smoke had the highest prevalence of menthol cigarette use among all racial and ethnic groups; the prevalence of menthol cigarette use among adults who smoke increased especially among Mexican American adults, younger adults, and adults who reported fair to poor health status.
