“…Exceptionally, living alone is a marker for social isolation that has been widely adopted. In Japan, the prevalence of living alone was reported to be 9-18% in community-dwelling older adults [11][12][13][14] and 15-21% in patients with cardiovascular diseases [15][16][17][18][19] . The corresponding prevalence in the study population was 24.5% (95% CI 20.1-28.8%), suggesting that the prevalence was at least not lower (or possibly slightly higher) than in other populations.…”

Assistance by family members or friends plays important roles in the course of treating patients with chronic limb-threatening ischemia (CLTI), both during hospitalization and after discharge. The aim of this study was to reveal the prevalence of social isolation and to explore relevant clinical backgrounds in patients with CLTI presenting with tissue loss and requiring revascularization. We analyzed 413 patients registered in a multicenter study in whom revascularization were scheduled for CLTI with tissue loss. Social isolation was analyzed by assessing the residence status of the patients and the involvement of a trusted family member or friend in their daily lives and during hospitalization. Patients living alone accounted for 24.5% (95% confidence interval [CI] 20.1–28.8%) of the study population. Patients receiving welfare were more likely to live alone (P < 0.001). For patients living alone, 21.8% (95% CI 12.8–30.8%) met a trusted family member or friend in their daily lives less than once per year. Younger age and receiving welfare were independently associated with lower frequency of meeting the trusted person in their daily lives (both P < 0.05). The adjusted odds ratio of age and receiving welfare was 0.44 (95% CI 0.29–0.67) per 10-year increase and 3.47 (95% CI 1.43–8.44), respectively. During hospitalization, 9.9% (95% CI 6.8–13.0%) of the patients had no hospital visits by a trusted family member or friend on three key occasions: the patient’s first hospital visit, the preoperative explanation regarding the planned operation, and the day of the operation. Younger age and receiving welfare were independently associated with lower frequency of hospital visits by a family member or friend (both P < 0.05). The adjusted odds ratio of age and receiving welfare for no visit versus ≥ 1 visit was 0.51 (0.36–0.74) per 10-year increase and 5.29 (2.46–11.4), respectively. In conclusion, social isolation is common among patients with CLTI, especially younger patients and those on welfare. Practical countermeasures against social isolation are warranted in the management of CLTI.

“…DVS validity has been adequately confirmed for energy, protein and the intake of some nutrients (17) . A low DVS is related to malnutrition, depression, poor sleep quality, lower physical performance and frailty among older adults (18)(19)(20)(21)(22)(23)(24)(25) . DVS is affected by various factors, such as age, gender, chewing ability, intellectual activity, living arrangements, economic status and food accessibility (17,(25)(26)(27)(28) .…”

Objective: Social networks are critical social health factors for older adults. This study examined the association between social networks and dietary variety among community-dwelling older adults. Design: A cross-sectional study, using the dietary variety score (DVS) developed for older Japanese people to assess dietary variety and the Lubben Social Network Scale (LSNS-6) to assess social networks. Setting: N City, H Prefecture, Japan. Participants: Community-dwelling older adults aged ≥ 65 years (n = 1,229). Results: The LSNS-6 score in the low DVS group was lower than that in the middle and high DVS groups (12.2 ± 5.6 vs. 13.4 ± 5.4 and 14.4 ± 5.7, P<0.001). The population of social isolation (LSNS-6, < 12) in the low DVS group was higher than that in the middle and high DVS groups (43.5% vs. 35.8% and 31.0%, P = 0.005). Multivariate linear regression analysis showed that the LSNS-6 score was positively correlated with DVS (standardized coefficient, 0.092; P = 0.002). Social isolation was also significantly associated with a low DVS in the multivariate-adjusted logistic analysis model (OR, 1.30; 95% CI, 1.00−1.68; P = 0.048). Stratified analysis results revealed the LSNS-6 and DVS were significantly associated in participants with the following characteristics: younger age (< 75 years), women, and those living with someone. Conclusions: Social networks were associated with dietary variety; social isolation was related to poor dietary variety among community-dwelling older adults. An association between social networks and dietary variety was observed among young-old older adults, women, and those living with someone.

(1) Objective: To examine the association between posterior-derived dietary patterns, food variety, and frailty measured by frailty index (FI) in Chinese elderly. (2) Method: A cohort study based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS) from 2014 to 2018 was conducted among older adults. The food variety was defined by the food variety score (FVS), which was calculated using the frequency of food categories consumption. Dietary patterns were obtained using factor analysis. A FI composed of 38 health deficits was used to measure subjects’ frailty status. Logistic regression analyses were performed to explore the correlation between dietary factors and the incidence of frailty. (3) Results: Compared with low FVS, a high dietary diversity score at baseline was not associated with a reduced incidence of frailty after four years. Regarding long-term food variety, compared with the low variety maintained group, people with high variety maintained were associated with a lower risk of frailty (0.59, 95%CI 0.39–0.90). Adherence to the “egg-bean-pickle-sugar pattern” and “fruit-vegetable-meat-fish pattern” was associated with a lower risk of frailty. (4) Conclusion: Maintaining high food variety and adherence to two patterns, i.e., the egg-bean-pickle-sugar pattern and fruit-vegetable-meat-fish pattern, could reduce the incidence of frailty among Chinese older adults.
