However, little is known about how smoking initiation, cessation, and intensity vary by birth cohort and race/ethnicity.<h4>Methods</h4>Adult smoking data were obtained from the 1978-2018 National Health Interview Surveys. Age‒period‒cohort models with constrained natural splines were developed to estimate historical smoking patterns among non-Hispanic White, non-Hispanic Black, Hispanic, non-Hispanic Asian and Pacific Islander, and non-Hispanic American Indian and Alaskan Native individuals. Annual smoking prevalence and probabilities of smoking initiation, cessation, and intensity by age, year, gender, and race/ethnicity were estimated for the 1900 to 2000 birth cohorts. Analysis was conducted in 2020-2021.<h4American journal of preventive medicinePatterns of Birth Cohort‒Specific Smoking Histories by Race and Ethnicity in the U.S.PMC10362802U01 CA253858U54CA229974U54 CA229974U01CA253858U01 CA199284U01CA199284Holford TRFleischer NLTam JMeza RCao PJeon JLevy DTfalsePatterns of Birth Cohort‒Specific Smoking Histories by Race and Ethnicity in the U.S.<h4>Introduction</h4>U.S. smoking prevalence varies greatly by race/ethnicity.
