Age and education have been found to affect the Mattis Dementia Rating Scale (MDRS) score of elderly normals, but there have been no studies assessing the influence of environmental and behavioral factors on this scale. Their role as potential predictors of the MDRS total score was investigated.
The MDRS was administered to 1,927 normal elderly subjects in the setting of a stroke prevention study. Results were correlated with 16 sociodemographic, environmental, and behavioral factors, and cerebrovascular risk factors. Study statistics resulted from multiple logistic regression analysis.
Results indicated that higher age and arterial hypertension were associated with poorer cognitive performance, while better education and moderate general life stress exerted a positive effect on the participants' test results.
Thus, besides the well-established factors of age and educational level, moderate general life stress and hypertension were identified as relevant predictors in determining the MDRS test performance of elderly normals.
研究发现年龄和教育程度会影响正常老年人的马蒂斯痴呆评定量表（MDRS）得分，但尚无研究评估环境和行为因素对该量表的影响。本研究调查了这些因素作为MDRS总分潜在预测指标的作用。
在一项中风预防研究中，对1927名正常老年受试者进行了MDRS测试。研究结果与16项社会人口统计学、环境和行为因素以及脑血管危险因素进行了相关性分析。研究统计结果来自多元逻辑回归分析。
结果表明，年龄较大和患有动脉高血压与较差的认知表现相关，而受教育程度较高和一般生活压力适度对参与者的测试结果有积极影响。
因此，除了已确定的年龄和教育水平因素外，一般生活压力适度和高血压被确定为决定正常老年人MDRS测试表现的相关预测指标。
