This work aims to validate and increase understanding of the Global Activity Limitation Index (GALI), an activity limitation measure from which the new structural indicator Healthy Life Years is generated.
Data from the Survey of Health and Retirement in Europe, covering 11 European countries and 27,340 individuals older than 50 years, was used to investigate how the GALI was associated with other existing measures of function and disability and whether the GALI was consistent or reflected different levels of health in different countries.
The GALI was significantly associated with the two subjective measures of activities of daily living score and instrumental activities of daily living (IADL) score, and the two objective measures of maximum grip strength and walking speed (P<0.001 in all cases). The GALI did not differ significantly between countries in terms of how it reflected three of the health measures, with the exception being IADL.
The GALI appears to satisfactorily reflect levels of function and disability as assessed by long-standing objective and subjective measures, both across Europe and in a similar way between countries.
本研究旨在验证并加深对全球活动受限指数（GALI）的理解，GALI 是一种活动受限测量指标，其中生成了新的结构指标“健康期望寿命”。
本研究使用了来自欧洲健康与退休调查的数据，涵盖了 11 个欧洲国家和 27340 名年龄在 50 岁以上的个体，旨在调查 GALI 与其他现有功能和残疾测量指标的相关性，以及 GALI 在不同国家是否一致或反映了不同的健康水平。
GALI 与两项主观日常生活活动评分（ADL）和工具性日常生活活动评分（IADL）以及两项客观最大握力和步行速度测量指标显著相关（在所有情况下 P<0.001）。除了 IADL 之外，GALI 在反映三种健康测量指标方面在各国之间并没有显著差异。
GALI 似乎能够令人满意地反映出欧洲和各国之间长期存在的客观和主观测量指标所评估的功能和残疾水平。
