The purpose of this study is to compare the ability of the Global Activity Limitation Indicator (GALI) and self-rated health (SRH) to predict all-cause mortality in the general adult population.
We linked the 2001 Belgian Health Interview Survey with mortality and migration registers 2001-2010. The baseline sample included 8,583 individuals aged 15 years and older. Poisson regression models were used to estimate the effect of the GALI and SRH on mortality rate during follow-up. We investigated the impact of gender, age, education and follow-up period on the association between the GALI/SRH and mortality.
The GALI and SRH were strong and complementary predictors of mortality in the Belgian adult population. Although the two global instruments shared some traits, they predicted mortality concurrently, with some indication of a somewhat stronger effect for SRH. We found neither significant differences between men and women, nor between education groups. The predictive effect of the GALI and SRH slightly decreased over time and the predictive effect of SRH slightly decreased with age.
Our findings suggest that the GALI and SRH are useful and complementary measures for assessing the health and functional status of adults in population surveys.
本研究旨在比较全球活动受限指标（GALI）和自评健康状况（SRH）对普通成年人群全因死亡率的预测能力。
我们将2001年比利时健康访谈调查与2001 - 2010年的死亡率和移民登记数据相联系。基线样本包括8583名15岁及以上的个体。采用泊松回归模型来估计GALI和SRH对随访期间死亡率的影响。我们研究了性别、年龄、教育程度和随访时间对GALI/SRH与死亡率之间关联的影响。
GALI和SRH是比利时成年人群死亡率的强有力且互补的预测指标。尽管这两个综合指标有一些共同特征，但它们能同时预测死亡率，且有迹象表明SRH的影响稍强一些。我们发现男性和女性之间以及不同教育程度组之间均无显著差异。GALI和SRH的预测效果随时间略有下降，且SRH的预测效果随年龄略有下降。
我们的研究结果表明，GALI和SRH是在人群调查中评估成年人健康和功能状况的有用且互补的指标。
