The purpose of this study was to examine the reversibility of the effect of smoking on hip fracture incidence rates.
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.
Among participants less than 75 years of age, the relative risk (RR) of hip fracture was elevated for ex-smokers, even for 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% CI = 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).
The effect of smoking on risk of hip fracture was not reversed completely 5 years after smoking cessation.
本研究旨在探讨吸烟对髋部骨折发病率影响的可逆性。
进行了一项为期3年的随访队列研究,纳入35767名50岁及以上的成年人。其中,421人发生了髋部骨折。
在75岁以下的参与者中,既往吸烟者髋部骨折的相对风险(RR)升高,即使是那些戒烟超过5年的人(男性:RR = 4.4,95%置信区间[CI] = 1.2,15.3;女性:RR = 1.3,95% CI = 0.6,3.0),但不如当前吸烟者高(男性:RR = 5.0,95% CI = 1.5,16.9;女性:RR = 1.9,95% CI = 1.2,3.1)。
戒烟5年后,吸烟对髋部骨折风险的影响并未完全逆转。
