Background: Dementia is the most important factor affecting everyday life of the elderly and there have been studies on the relationship between dementia and social withdrawal or loneliness. However, there is a lack of investigations on the relationship between loneliness and cognitive function in the elderly living alone.
Methods: Ninety five community-dwelling elderly people registered to Sungbook elderly welfare center in Seoul, who were living alone, were enrolled in the study. Personal visits by three pre-trained researchers were made during April 2006. One year later, 11 elderly dropped out, and 84 elderly were interviewed in the same way. They were interviewed based on loneliness scale, social support, Hasegawa dementia scale, instrumental activities of daily living, and depression.
Results:The mean age of the subjects was 78.3 years. Most of them were women (90.5%) and education level was low (no schooling in 69%). The loneliness scale did not change much during one year (P=0.63), but the instrumental activities of daily living (IADL) score had worsened from 10.5 to 11.2 (P=0.002) The mean Hasegawa dementia scale score decreased from 23.2 to 21.0 during one year (P<0.001). Multivariate regression analysis for the one-year difference in Hasegawa Dementia Scale revealed loneliness was a significant factor after adjusting for age, the level of education, social support, IADL score, and depression (regression coefficient=?0.712, P=0.02).
Conclusion: Loneliness was associated with a decline in cognitive function in the elderly people living alone. In contrast, social withdrawal and depression had no effect on changes of cognitive function during one year.
