A cross-sectional study was conducted to quantitatively evaluate the relationship between the instrumental activities of daily living (IADL) and various physical fitness tests in elderly women living at home. The study focused on the total population of those women aged 65 years and over living in Y Town, Hyogo Prefecture, Japan, who visited a nursing home for day services. A total of 128 subjects were divided into two groups: dependent in IADL group (n = 49) and independent in IADL group (n = 79). The magnitude of the relation was evaluated by the odds ratio (OR). The following tests showed a significant decrease in IADL: knee-raising test [age-adjusted OR=4.23, 95% confidence interval (CI) 1.81-9.87], height (age-adjusted OR=4.09, 95% CI 1.75-9.56), grip strength (age-adjusted OR=3.68, 95% CI 1.57-8.60), sit-and-reach test (age-adjusted OR=2.76, 95% Cl 1.20-6.34), and standing on one leg with closed eyes (age-adjusted OR=2.56, 95% Cl 1.09-5.97). Multivariate analysis' using Hayashi's quantification method I indicated that knee-raising was the test most highly correlated with decreased IADL. These results suggest that measurement of knee-raising ability, muscle strength of the lower extremities and flexibility of hip joint could be the most useful factors to assess the level of instrumental self-support ability.
