[Non-participation in social activities of rural older adults: Results from the Toyama dementia survey].

Objective　Social activities play an important role in the maintenance of health and well-being of the older adults. The aim of this study was to identify characteristics of the rural older adults who do not participate by type of social activities.Methods　This survey examined 1,537 older adults randomly selected at a sampling rate of 0.5% from among those living in Toyama prefecture of Japan, in 2014. Of the total, 947 ambulatory older adults living in their own homes were analyzed using Poisson regression. Results were presented as prevalence ratio (PR). The level of statistical significance was set at P<0.05 (two-sided test).Results　The participants included 426 men (mean age 73.9 ± 6.5 years) and 521 women (mean age 74.8 ± 7.0 years).　In terms of work, both men and women did not work at an older age (men PR 1.15 over 75 years old, women PR 1.11 over 70 years old). Men did not work during outpatient treatment (PR 1.09) and the Revised Hasegawa Dementia Scale (HDS-R) 21-25 points (PR 1.09) and 20 points or below. Women who did not drink alcohol did not work (PR 0.93).　Both men and women did not participate in residential activities at older ages (men PR 1.12 over 70 years old, women PR 1.11 over 80 years old). Men with 20 points or below on HDS-R (PR 1.16) and with work history of only physical labor (PR 1.12), and women living with family (PR 0.92) were less likely to participate in residential activities.　In the hobby group, both men and women with work history of only physical labor were less likely to participate (men PR 1.05, women PR 1.08). Men with education of 9 years or below (PR 1.05) and women living alone (PR 1.07) were less likely to participate. Hobby groups did not relate with age and cognitive decline.　In the senior citizens' club, men and women who did not drink alcohol were less likely to participate (men PR 0.91, women PR 0.89). Men who smoked (PR 1.06), men with psychological symptoms (PR 1.09), and women with 20 points or below on HDS-R (PR 1.13) were less likely to participate.Conclusion　Factors related to non-participation of older adults in rural cities depended on the type of social activities. In order to promote social activity among the older adults in rural cities, it is important to consider specific measures taking into account the type of social activities.
