A Longitudinal Study of Physical Fitness related to Activities of Daily Living among the Elderly Women Living at Home
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.16 Vol.16】
A follow−up study was conducted for 76 healthy elderly women living at home, whose ages ranged from 65 to 90 years with mean of 77.4, to clarify the changes of instrumental activities of daily living (IADL, consisted of 5 functions such as shopping, transportation, etc.) and items of physical fitness test such as height, body weight, body mass index (weight/height²), grip strength, sitting stepping, standing on one leg with opened eyes, standing on one leg with closed eyes, sit and reach test, jumping reaction time and knee raising test, as well as to find a physical fitness tests concisely to evaluate the decrease of IADL. Initial investigations were conducted in June 1993 and the second in June 1994 on the same subjects.
A total of 71 subjects, for a follow−up rate of 93.4%, were surveyed the second IADL status and a total of 66 subjects (86.8%) attended to both second IADL and fitness investigations. About 20% of subjects had decreased in at least one of the five IADL functions. Among the items of physical fitness test, mean values of sit and reach test was only significantly increased from 5.0 cm to 6.8 cm (P < 0.01).
Subjects were classified into 2 groups of IADL status, a decrease group and a maintenance and/or increase group. All physical fitness tests were grouped into two categories that divided variables in the median.
According to the results after cross table analysis, the decrease of IADL were significantly associated with standing on one leg with closed eyes and knee raising test (relative risk = 3.57, 95% confidence interval 1.06 - 11.99, respectively). On the other hand, there were less associations between body weight (relative risk = 0.73, 95% confidence interval 0.28 - 1.92), body mass index (relative risk = 0.97, 95% confidence interval 0.37 - 2.53) and the decrease of IADL. Therefore, the robust relationships between standing on one leg with closed eyes, knee raising test and IADL status were confirmed.
This study demonstrated that the practice of standing on one leg with closed eyes and knee raising test were particularly effective to grasp the decrease of IADL among the elderly women living at home.
