A variety of factors being widely known to be related to cognitive impairment by was investigated using the existing comprehensive geriatric assessment. By using MMSE-K (Korea version of Mini- Mental State Examination), the relation between cognitive impairment and each variable was analyzed by using chi-square test and logistic regression analysis with SPSS 10.0k/PC statistical program.
Results: The number of males and females was 73 (36.5%) and 127 (63.5%), respectively, among the total number of 200 examinees. Males and females having symptoms of cognitive impairment was 25 (34.2%) and 49 (38.6%) among the total number of 74 (37%), respectively. Total mean point of MMSE-K was 24⁑5.4, 24⁑5.3 in males and 23.9⁑5.5 in females. According to the results of multi-variable quantities analysis, it was shown that the cognitive impairment had positive relation to age (P= 0.004), but negative relation to regular exercising (P= 0.016), instrumental activities of daily living (P=0.039) and social support (P=0.003).
