Association Between Smoking, Smoking Cessation, and Mortality by Race, Ethnicity, and Sex Among US Adults

JAMA Network Open

Using data from the U.S. National Health Interview Survey, this study looked at the association, by race, ethnicity, and sex, of cigarette smoking and cessation with all-cause/cause-specific mortality. Comparing those who quit smoking before age 45 years with never-smokers, all-cause mortality rate ratios (RRs) were noted in the following groups: 1.15 Hispanic, 1.16  non-Hispanic Black, 1.11 non-Hispanic White, and 1.17 other non-Hispanic persons. Current smoking was associated with substantial excess mortality in all groups. Quitting smoking before age 45 years was associated with close to 90% reduction in the excess mortality risk associated with continued smoking; quitting at ages 45-64 years was associated with a 66% risk reduction irrespective of race and ethnicity.
