BACKGROUND Considering that mortality rate and deficit accumulation varies considerably in men and women, we performed a sex-stratified analysis of the association between an estimated frailty index (eFI) with 6-year mortality in the Activity and Function in the Elderly (ActiFE) Study. METHODS We constructed an eFI using a score (0 [no deficit] to 1 [deficit]) from 32 baseline items representing multiple domains. eFI represents the sum of all scores divided by 32. Cox proportional hazards models adjusted for age, smoking, alcohol intake, and education were used to evaluate this association. RESULTS Among 1,204 participants (57.5% men), 18.5% men and 26.0% women were frail (eFI ≥ 0.2) with an age-adjusted mean eFI of 0.13 (95% confidence interval [CI] 0.12, 0.13) and 0.15 (95% CI 0.15, 0.16), respectively. Mortality rate in men (146 deaths) was 34.4 (95% CI 29.3, 40.5) and in women (50 deaths) 15.1 (95% CI 11.5, 19.9) per 1,000 person-years. A 0.1 increment of eFI was associated with a hazard ratio (HR) of 1.94 (95% CI 1.60, 2.35) in men and 2.06 (95% CI 1.58, 2.69) in women. Frail versus nonfrail men and women had a HR of 2.46 (95% CI 1.74, 3.48), and 2.98 (95% CI 1.55, 5.70), respectively. We detected sex differences in the order of the eight common contributor items to the eFI. CONCLUSIONS We observed a statistically significant difference for the age-adjusted eFI and the frailty prevalence in men and women. However, our analysis does not suggest the presence of effect modification by sex in the association with mortality.

社区居住的老年人的体弱指数和特定性别的6岁死亡率:ActiFE研究。

背景技术考虑到男女的死亡率和赤字积累差异很大,我们对老年人的活动和功能(ActiFE)研究中的估计脆弱指数(eFI)与6年死亡率之间的关系进行了性别分层分析。 。方法我们使用32个代表多个领域的基线项目的得分(0 [无赤字]至1 [赤字])构建了eFI。eFI代表所有得分的总和除以32。针对年龄,吸烟,饮酒和教育程度进行了调整的Cox比例风险模型用于评估这种关联。结果在1,204名参与者中(男性占57.5%),男性18.5%和女性26.0%较弱(eFI≥0.2),年龄校正后的平均eFI为0.13(95%置信区间[CI] 0.12、0.13)和0.15(95%) CI分别为0.15、0.16)。每千人年的男性死亡率(146死亡)为34.4(95%CI 29.3,40.5),女性(50死亡)15.1(95%CI 11.5,19.9)。eFI的0.1升高与男性的危险比(HR)为1.94(95%CI 1.60,2.35)和女性为2.06(95%CI 1.58,2.69)有关。体弱与不体弱的男性和女性的HR分别为2.46(95%CI 1.74、3.48)和2.98(95%CI 1.55、5.70)。我们按照eFI的八个共同贡献者项目的顺序检测到性别差异。结论我们观察到男女年龄校正后的eFI和虚弱患病率在统计学上有显着差异。但是,我们的分析并未表明与死亡率相关的性别改变效应的存在。eFI的增加1与男性的危险比(HR)为1.94(95%CI 1.60,2.35)和女性为2.06(95%CI 1.58,2.69)有关。体弱与不体弱的男性和女性的HR分别为2.46(95%CI 1.74、3.48)和2.98(95%CI 1.55、5.70)。我们按照eFI的八个共同贡献者项目的顺序检测到性别差异。结论我们观察到男女年龄校正后的eFI和虚弱患病率在统计学上有显着差异。但是,我们的分析并未表明与死亡率相关的性别改变效应的存在。eFI的增加1与男性的危险比(HR)为1.94(95%CI 1.60,2.35)和女性为2.06(95%CI 1.58,2.69)有关。体弱与不体弱的男性和女性的HR分别为2.46(95%CI 1.74、3.48)和2.98(95%CI 1.55、5.70)。我们按照eFI的八个共同贡献者项目的顺序检测到性别差异。结论我们观察到男女年龄校正后的eFI和虚弱患病率在统计学上有显着差异。但是,我们的分析并未表明与死亡率相关的性别改变效应的存在。我们按照eFI的八个共同贡献者项目的顺序检测到性别差异。结论我们观察到男女年龄校正后的eFI和虚弱患病率在统计学上有显着差异。但是,我们的分析并未表明与死亡率相关的性别改变效应的存在。我们按照eFI的八个共同贡献者项目的顺序检测到性别差异。结论我们观察到男女年龄校正后的eFI和虚弱患病率在统计学上有显着差异。但是,我们的分析并未表明与死亡率相关的性别改变效应的存在。
