Factors related to coping with physical and instrumental activities of daily living among people born in 1904–1923

Abstract Functional ability is affected by a number of different factors, including biological ageing, illness, and living environment. This study was concerned with the connections of functional ability with mood and cognitive capacity in elderly individuals. It forms part of a cross‐sectional study which was carried out in 1988, involving two random samples of 800 non‐institutionalized persons born in 1904–1913 and 1914–1923. Functional ability tests included 18 questions; eight concerned coping with physical activities of daily living (PADL) and 10 instrumental activities of daily living (IADL). Depressive symptoms and cognitive capacity were examined by tests. In addition, there was a set of questions concerning health status and socioeconomic situation. Regression models (LISREL) were used to identify factors associated with PADL and IADL activities. In the younger age group, 68% of the men and 65% of the women had no difficulty in coping with PADL activities. The figures for the older group were 58% and 37%, respectively. Difficulties were reported more frequently with IADL activities. In the older age group 17% of the men and 10% of the women coped with no difficulty. In all activities difficulties tended to increase with age, and more so among women than men. The explanatory factors that emerged from the regression models as most significant were the number of chronic illnesses, the number of depressive symptoms and cognitive capacity.
