目的评估老年人虚弱的患病率和10年预后与缺陷积累的关系。前瞻性队列研究。加拿大全国人口健康调查，以基线（1994/95年）估计的脆弱程度和2004/05年的死亡率跟踪情况。参与者：来自加拿大10个省的65至102岁的社区居住老年人（N= 2740, 60.8%为女性）。在10年的随访中，1208人死亡。测量方法使用自我报告的健康信息来构建虚弱指数（脆弱指数），作为个体累积缺陷的比例。主要结局指标是死亡率。结果男性和女性的衰弱患病率随着年龄的增长而增加(相关系数=0.955 ~ 0.994，P
OBJECTIVESTo evaluate the prevalence and 10-year outcomes of frailty in older adults in relation to deficit accumulation.DESIGNProspective cohort study.SETTINGThe National Population Health Survey of Canada, with frailty estimated at baseline (1994/95) and mortality follow-up to 2004/05.PARTICIPANTSCommunity-dwelling older adults (N=2,740, 60.8% women) aged 65 to 102 from 10 Canadian provinces. During the 10-year follow-up, 1,208 died.MEASUREMENTSSelf-reported health information was used to construct a frailty index (Frailty Index) as a proportion of deficits accumulated in individuals. The main outcome measure was mortality.RESULTSThe prevalence of frailty increased with age in men and women (correlation coefficient=0.955-0.994, P
