The aim of this study was to examine the effect of health factors on memory performance in a population-based sample of 679 older people (mean age=69.2 years).
Both subjective and objective indices of health were used as predictor variables. Memory performance was measured with an immediate recall test and a delayed recall test.
Some of the objective health indices were correlated with performance on the memory tasks, but regression analysis showed that they hardly had a unique effect on memory performance.
Health factors have only a weak relationship with memory performance in older adults.
本研究旨在调查健康因素对679名老年人（平均年龄=69.2岁）的基于人群样本的记忆表现的影响。
健康的主观和客观指标均用作预测变量。通过即时回忆测试和延迟回忆测试来测量记忆表现。
一些客观健康指标与记忆任务的表现相关，但回归分析表明它们对记忆表现几乎没有独特影响。
健康因素与老年人的记忆表现仅有微弱关系。
