Effect of type 2 diabetes with hypertension on cognitive function——a study on elderly living in the communities of Beijing / 中华流行病学杂志

ABSTRACT

Objective To study the effects of type 2 diabetes (T2DM) with hypertension on cognitive function in those community-based elderly who were aged 60 and over,in Beijing.Methods 82 patients with T2DM,142 patients with both T2DM and hypertension and 277 normal controls were investigated in this study.Both methods as:the Montreal Cognitive Assessment (MoCA) and Mini-Mental Status Examination (MMSE) were used to determine cognitive change.Results The total MMSE scores showed significant decrease between T2DM with hypertension and controls [(28.42± 1.52) vs.(28.88± 1.47),P＜0.05].The MoCA score of the total scores [(25.20± 3.91) vs.(26.50 ± 3.29),P＜0.05],sub-scores of visuospatial,executive [(3.60± 1.56) vs.(3.96± 1.18),P＜0.05] and language [(2.10± 0.80) vs.(2.37± 0.80),P＜0.05] significantly decreased in T2DM patients with hypertension and in the normal controls.Data from the Multiple logistic regression analysis showed that older age and less education were risk factors for cognitive impairment.Conclusion T2DM and hypertension damaged the cognitive function of patients.
