Association between Cognitive Impairment and ADL of the Elderly in Rural Area

  • 1Department of Preventive Medicine and Public Health, College of Medicine, Yeungnam University.


The purpose of this investigation was to study the correlation between cognitive impairment and activities of daily living(ADL) in the elderly of rural area.
The study population consisted of 210 elderly people aged 65 years and older, living in a district of Kyongju City. The cognitive impairment was measured with the Korean version of mini-mental state examination(MMSE-K) and newly constructed the Korean version of mini-mental state examination (K-MMSE). Bristol activities of daily living scale developed specifically to be used with people with dementia was used to measure ADL.
The mean scores of both MMSE-K and K-MMSE were significantly different by sex groups and by age groups, respectively(p<0.05). The mean scores of ADL were significantly different by age groups(p<0.01) not by sex groups. Among the 4 components of ADL(instrumental activities of daily living(IADL), self care, orientation, and mobility), the mean score of the orientation was significantly higher in men(p<0.01); and IADL, orientation and mobility components were significantly different by age groups(p<0.01). ADL correlated well with MMSE-K (r=0.54) and K-MMSE(r=0.52) and showed higher correlation in female (r=0.73, 0.71) than male(r=0.27, 0.29). IADL and orientation showed significant correlation with MMSE-K(r=0.52, 0.62) and K-MMSE(r=0.50, 0.63), respectively(p<0.01).
In developing and establishing a care model for people with dementia in the community, both cognitive impairment and the activities of daily living(ADL) need to be considered.
