The study aims at assessing the relative importance of specific versus general self-reported indicators of health and disability in predicting mortality among older adults and at exploring the potential value of the global activity limitation indicator (GALI), a recently validated general measure of activity restrictions, as predictor of death.
Longitudinal data from two waves (2004 and 2006-2007) of the Survey of Health, Ageing and Retirement in Europe were employed. The sample comprises 17,941 persons aged 50+ at baseline, representing 11 countries. Associations were estimated by sex using Cox's proportional hazards regression models.
Most specific and general indicators of health and disability are strong and independent predictors. There are disparities by sex; among general measures, controlling for all indicators under consideration, self-rated health (SRH) only remains significantly associated with mortality among males and GALI among females.
A combination of specific and general measures is more efficient in predicting mortality than either of these alone. SRH and GALI seem to share some traits, adding health and disability dimensions over specific measures, representing though different aspects by gender.
本研究旨在评估特定与一般自我报告的健康和残疾指标在预测老年人死亡率方面的相对重要性，并探索全球活动受限指标（GALI）作为死亡预测指标的潜在价值，GALI是最近验证的一种活动受限的一般测量方法。
采用欧洲健康、老龄化和退休调查两轮（2004年以及2006 - 2007年）的纵向数据。样本包括基线时年龄在50岁及以上的17941人，代表11个国家。使用Cox比例风险回归模型按性别估计关联。
大多数特定和一般的健康及残疾指标都是强有力的独立预测指标。存在性别差异；在一般测量指标中，在控制所有考虑的指标后，自我评估健康状况（SRH）仅在男性中与死亡率显著相关，而GALI在女性中与死亡率显著相关。
特定和一般测量指标相结合在预测死亡率方面比单独使用其中任何一种都更有效。SRH和GALI似乎有一些共同特征，在特定测量指标之上增加了健康和残疾维度，不过按性别代表不同方面。
