This study was performed to provide the basic data and related factors available for the assessment of the degree of ADL and depression among older persons, manifesting their physical and psychological status. The subjects included the old people aged more than 65 years old who reside in urban areas. The interviews were delivered to 693 individuals in Taejon metropolitan city during the two-month period from June to July, 2000, and Zung Self-Rating Depression Scale and IADL developed by Older American Resources and Services of Duke medical college, were employed for the assessment of depression and IADL, respectively. The collected data were statistically processed by SPSSWIN(ver 10.0) and led to the following results.
The degree of depression among 635 subjects showed that 26.6% had mild depression, 8.2% moderate and 0.6% severe while 64.6% were normal. In terms of IADL, 6.9% had impossible IADL when not aided by others, 37.0% needed some help, 56.0% possible IADL, and the higher depression scores, the significantly higher IADL scores. Based on general characteristics, depression scores were significantly higher in the female group, the older, the lower educated, the ones without cohabitants, without a spouse, without making expenses of living on their own, and IADL scores were lower, meaning the lower capability for performing daily activities, in the male group, the older, the higher educated, the group without a spouse, without making expenses of living on their own. Based on daily activities and psychological characteristics, depression scores were higher in the group who don’t go out, who don’t have recreational or friendly gatherings, who aren’t satisfied with the lives of the past or present, who have a sense of isolation, and who don’t have the will to live, and IADL scores were lower in the group who don’t go out, who don’t have recreational or friendly gatherings, who aren’t satisfied with the lives of the past or present, who have a sense of isolation. and who don’t have the will to live. Multiple regression analysis revealed that the explanatory variable having effects on depression symptoms included, with the explanatory power of 57.5%, the confidence in life, the degree of education, the subjective index of health, the sense of isolation, the exercise, the degree of IADL, the gender, the level of satisfaction with life, whether they eat breakfast or not, the concern about life, the smoking, the going out, the presence of spouse or not. The explanatory variables having effects, with the explanatory power of 28.9%, on IADL scores included the degree of depression symptoms, the age, the presence of friends or not, the frequency of outgoing, the level of education, the degree of obesity, the confidence in life, the level of satisfaction with life, the drinking or not.
The study results showed that the higher depression scores had a tendency to be associated with the decreased capabilities of performing daily activities, and that the factors related to depression and/or IADL, included the confidence in life, the level of education, and the level of satisfaction with life. However, the more detailed and decisive results on the factors related to depression and IADL of the older persons are considered to require continuing efforts and comparisons among a variety of the older population.
