[BDSP. Notice produite par INIST 434R0x95. Diffusion soumise à autorisation]. Objectives. The purpose of this study was to examine the reversibility of the effect of smoking on hip fracture incidence rates. Methods. A 3-year follow-up cohort study was conducted involving 35 767 adults 50 years of age or older. Of these individuals, 421 suffered a hip fracture. Results. Among participants less than 75 years of age, the relative risk (RR) of hip fracture was elevated for ex-smokers, even tor those who had quit smoking more than 5 years previously (men : RR=4.4,95% confidence interval [CI ] 1.2,15.3 ; women : RR=1.3,95% Cl=0.6,3.0), but was not as high as that for current smokers (men : RR=5.0,95% CI=1.5,16.9 ; women : RR=1.9,95% CI=1.2,3.1). Conclusions. The effect of smoking on risk of hip fracture was not reversed completely 5 years after smoking cessation.
