[Characteristics of geriatric syndrome-subjects who did not participate in proffered intervention trial]

The present study was conducted to identify the characteristics of non-participants in intervention for geriatric syndrome among community-dwelling elderly.

The subjects were 208 men and 399 women aged 70 years and over who were eligible for participation in intervention programs for geriatric syndrome (falls, urinary incontinence, depression, and malnutrition) after recruitment based on a baseline health examination survey in 2002. Multiple logistic regression analysis was performed to assess non-participation in the intervention program as a dependent variable, and the relevant characteristics for participation in the baseline survey as the independent variables.

The rates of participation in the intervention were 16.8% for men and 32.6% for women. Logistic regression analysis showed that male non-participants had not participated in group social activity (odds ratio (OR)=2.46, 95% confidence interval (CI) 1.08-5.59), and had no medical history of heart disease (OR=0.38, 95%CI 0.17-0.89), whereas female non-participants had not lived alone (OR=0.53, 95%CI 0.34-0.83), and had no medical history of hyperlipemia (OR=0.54, 95% CI 0.34-0.84).

Social activity, living arrangement, and medical history are related to non-participation in intervention for geriatric syndrome. It is necessary to devise various intervention programs and approaches to encourage participation.
