    Article - En anglais

    Fulltext.

    Objectives

    A model that relates clinical risk factors to subsequent mortality was used to simulate the impact of smoking cessation Methods.

    Survivor functions derived from multivariate hazard regressions fitted to data from the first National Heath and Nutrition Examination Survey (NHANES 1) Epidemiologic Followup Study, a longitudinal survey of a representative sample of US adults, were used to project deaths from all causes.

    Results

    Validation tests showed that the hazard regressions agreed with the risk relationships reported by others. that projected deaths for baseline risk factors closely matched observed mortality. and that the protections attributed deaths to the appropriate levels of important risk-factors, Projections of the impact of smoking cessation showed that the number of cumulative deaths would be 15% lower after 5 years and 11% lower after 20 years Conclusions.

    The model produced realistic projections of the effects of risk factor modification on subsequent mortality in adults.

    Comparison of the projections for smoking cessation with estimates of'the risk attributable to smoking published by the Centers for Disease Control and Prevention suggests that cessation could capture most of the benefit possible from eliminating smoking.
