  1. Smoking cessation and mortality trends among two United States populations. Commentary. Author's reply.

    Article - En anglais

    The long-term impact of smoking cessation on mortality is assessed among two U.S. populations : a large cohort of U.S. veterans aged 55-64 at entry and followed from 1954 through 1979 and the NHANES I Epidemiologic Followup Study (NHEFS) cohort of a national sample of U.S. adults aged 55-74 at entry and followed from 1971 through 1992.

    Direct and indirect survey data indicate that 50-70% of those who were current cigarette smokers at entry had quit smoking during the 19-to 26-year follow-up periods.

    The impact of smoking cessation on mortality among the cigarette smokers as a whole has been assessed by determining the time trend of the relative risk (RR) of death and 95% confidence interval (Cl) for the cigarette smokers compared with never-smokers over the entire follow-up period in both cohorts.

    The total death rates for the 1954/57 U.S. veteran smokers as a whole (63,159 males) have converged only slightly toward those of never-smokers, from RR=1.65 (1.58-1.72) during 1954-1959 to RR=1.61 (1.58-1.63) during 1954-1979.

    The lung cancer death rates for 1954/57 smokers as a whole have not converged toward those of never-smokers, with RR=10.89 (7.70-15.41) during 1954-1959 and RR=11.10 (9.78-12.61) during 1954-1979.

    The total death rates for the 1971-1975 NHEFS smokers as a whole (694 males and 1116 females) have not converged toward those of never-smokers.

    For males, RR=1.92 (1.46-2.52) during 1971-1982 and RR=1.96 (1.63-2.36) during 1971-1992 ; for females, RR=1.79 (...)
