ABSTRACT

Objective To explore the risk factors of cognitive impairment in rural elderly patients from Changzhi urban. Methods Totally 118 elderly patients were examined with minimental state examination (MMSE). The common data and histories of coronary heart disease,hypertension,diabetes and chronic obstructive pulmonary disease were collected. Results The prevalence of cognitive impairment was 14.4％.Multivariate analysis showed that MMSE scores was associated with age,stroke history,homocysteine and low density lipoprotein(LDL-C) (x2 =21.166,19.323,13.672,3.698,P＜0.01 or P＜0.05),and cognitive impairment was not associated with gender,alive spouse,hypertension,coronary heart disease, diabetes and chronic obstructive pulmonary disease(P＞0.05).Age(OR=0.853,95％ CI0.765-0.951),stroke history(OR=0.764,95％ CI0.629-0.929),LDL-C (OR =0.208,95％ CI0.062-0.701 ) and activities of daily living (ADL)(OR=0.839,95％ CI0.725-0.972)were independent risk factors of cognitive impairment in rural elderly patients.
