ObjectiveStudies have suggested that frequent participation in social groups contributes to the well-being of older people. The primary aim of this study was to identify the number of days older adults should participate in the activities of social groups to maintain their health for 4 years. This study also aimed to examine whether the effective frequency differs by the type of social group activity.MethodWe examined a prospective cohort of 1,320 community-dwelling older adults over 65 years of age, who responded to both a baseline and a follow-up mail survey, in a suburban city of Tokyo, Japan. The dependent variable was the change in functional competence during 4 years. Logistic regression analyses were conducted to examine the effects of participation in the activities of the 5 most common social groups among older Japanese on maintaining functional competence.ResultsNine hundred and ninety-four participants (76.5%) maintained their functional competence for 4 years. The results of the logistic regression analyses showed that participating in alumni groups less than once a month and being an inactive member were associated with higher odds of maintaining functional competence, after controlling for socioeconomic, demographic and baseline health status. Additionally, the odds of maintaining functional competence for 4 years increased upon participating in volunteer groups once a month or more. These results were also confirmed using logistic regression analysis, even after adjustment for the effects of participation in other social groups.DiscussionThe results indicated the effectiveness of volunteer activities that fulfill a social role in maintaining health. Therefore, older adults should be encouraged to participate in activities of volunteer groups at least once a month. Additionally, older adults can obtain positive health outcomes through less frequent participation in alumni groups, compared with the activities of volunteer groups.

“…We defined the terms "isolation" and "homeboundness" based on the definitions provided by Fujiwara et al 15 . This definition uses questions on in-person social contact ("How often do you see or go out with friends, neighbors, and family members who do not live at your dwelling?")…”

“…12 Although operative definitions of these terms vary from study to study, the reported incidences of social isolation and homeboundness in the elderly are 7-17% 13 and 5.6%, 14 respectively. Fujiwara et al 15 defined social isolation as having less than one interaction with others per week, regardless of whether the interaction is in person or not, and homeboundness as leaving the house less than once a day. They surveyed these parameters in community-dwelling elderly and found that the incidences of social isolation and homeboundness were 34.4% and 22.9% for men and 15.6% and 32.9% for women, respectively, and that these parameters were associated with decline in high-level functional capacity.…”

To determine the frequency of social isolation (hereinafter, isolation) and homeboundness in elderly diabetic patients and to investigate their relationships with high-level functional capacity. Patients and Methods: Subjects were diabetic outpatients aged 65 years and older who were visiting the Japanese Red Cross Ise Hospital. Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) was used to evaluate high-level functional capacity. Isolation was defined as having less than one interaction per week with someone other than co-habiting family members. Homeboundness was defined as leaving the house less than once a day. Multiple regression analysis was performed with the TMIG-IC score as the dependent variable and isolation and homeboundness as independent variables. Results: Four hundred fifty-one patients were included in the analysis. The frequency of isolation and homeboundness affected 37% and 13.3% of men and 28.9% and 20.6% of women, respectively. The adjusted partial regression coefficient of the TMIG-IC scores of isolated, homebound, and isolated+homebound men was −0.94 [95% confidence interval (CI), −1.68 to −0.21; P = 0.012], −0.27 (95% CI, −1.93 to 1.39; P = 0.746), and −4.03 (95% CI, −5.37 to −2.68; P < 0.001) in relation to that of the non-isolated and non-homebound group as reference. In women, the respective coefficients to the reference were −1.33 (95% CI, −2.93 to 0.25; P = 0.099), −0.65 (95% CI, −2.56 to 1.26; P = 0.501), and −3.01 (95% CI, −4.92 to −1.1; P = 0.002), respectively. Conclusion: The frequency of isolation was high in both female and male elderly diabetic patients. In men, there was a significant relationship between isolation and decline in highlevel functional capacity. In both men and women, there was a significant relationship between isolation+homeboundness and decline in high-level functional capacity.
