Mini mental state examination: influence of sociodemographic, environmental and behavioral factors and vascular risk factors.
Age and education have been found to affect the Mini Mental State Examination (MMSE) score of elderly normals, but there have been no studies assessing the influence of environmental and behavioral factors on this test. We therefore administered the MMSE to 1437 normal elderly subjects in the setting of a stroke prevention study and correlated their results to 16 sociodemographic, environmental, and behavioral factors, and vascular risk factors. Study statistics composed of a multiple logistic regression analysis and graphical models revealed the relations between variables in greater detail. Logistic regression yielded education level, occupational status, living as a single, general life stress, physical strain, and physical inactivity to be independent predictors of the MMSE score. Age was not included in this model. Graphical models demonstrated similar results, but did not include living as a single and physical inactivity. As shown in our independence graph, general life stress is the crucial predictor and links other environmental and sociodemographic variables with the test performance of elderly normals.
