Aim: The purpose of this study was to examine the relationship between health-related quality of life (QOL) and swallowing function among independent community-dwelling older Japanese adults aged 65 years or older.

Methods: A total of 500 participants (250 males and 250 females) were surveyed about BMI, dysphagia and eating disorders (Dysphagia Risk Assessment for the Community-dwelling Elderly [DRACE]), quality of life (QOL; SF-8 Physical and Mental Summary Score), sleep (Pittsburgh Sleep Questionnaire Japanese version [PSQI-J]), and depression (Geriatric Depression Scale [GDS]).

Results: Participants were divided into two groups based on risk of aspiration and data between the groups were compared. Logistic regression analysis revealed that the SF-8 physical component summary score (PCS) and mental component summary score (MCS) were associated with aspiration risk. In the multiple regression analysis, the SF-8 related to eating and swallowing function and PSQI-J were extracted.

Conclusions: The risk of aspiration among the older adults in this study was found to be associated with health-related QOL, sleep quality, revealing a wide-ranging impact on physical, mental, and social functioning. These associated factors may pose a risk for community-dwelling independent older adults, suggesting the need to focus on eating and swallowing function for frailty.

Purpose: This study investigated the factors associated with oral frailty among community-dwelling older adults. In particular, we compared the factors between individuals in the young-old and old-old groups and clarified the differences between the two groups.

Methods: We measured the basic attributes, body composition, grip strength, gait function, oral function, cognitive function, and daily living function using the Kihon checklist in older people living independently in T City, Aichi Prefecture. The risk of oral frailty was assessed using the Oral Frailty Screening and Evaluation Form (OFI-8), and the measurement results were compared between two groups: those with and those without risk. To identify the factors associated with oral frailty, we performed a multivariate analysis with the risk of oral frailty as the dependent variable and a univariate analysis separately for the young-old and old-old groups.

Results: The mean age of the 100 subjects was 76.6±4.6 years old. Forty-four subjects were at risk of oral frailty, and 55 subjects were not at risk. The high-risk group had significantly higher rates of polypharmacy, depression, and a slow walking speed than the no-risk group. The risk factors associated with oral frailty were living alone, polypharmacy, and depression. The risk factors for oral frailty were a poor ambulatory function in the young-old and a poor ambulatory function, decline in the cognitive function, and depression in the old-old.

Conclusions: The results of this study suggest that the risk factors for oral frailty differ between older individuals in the young-old and old-old groups and that age-appropriate support is necessary to prevent oral frailty in older people.

Aim: Some studies have reported a higher incidence of falls during winter with similar proportions of indoor and outdoor falls. We investigated the relationship between indoor temperature during winter and falls at home in the past year among community-dwelling older adults.

Methods: This cross-sectional study enrolled 964 individuals of ≥65 years of age in Japan. Participants answered questions about falls (including trips) at home within the past year, and the living room temperature was measured for 2 weeks during winter. Participants were divided into those living in cold (mean temperature near the floor <12°C), slightly cold (12-17.9°C), and warm (≥18°C) houses. The association between indoor temperature (cold vs. slightly cold vs. warm houses) and falls at home in the past year was examined using a logistic regression analysis adjusted for potential confounding factors.

Results: Valid data were obtained from 907 participants (mean age: 72.0±6.3 years), of whom 265,553, and 89 lived in cold, slightly cold, and warm houses, respectively. In the past year, falls occurred once in 325 (35.8%) participants and multiple times in 148 (16.3%) participants. In warm houses, the odds ratio of falling once and multiple times in the past year was 0.49 (p=0.032) and 0.34 (p=0.035), respectively, in comparison to cold houses.

Conclusions: Living in cold houses may be associated with an increased risk of falling at home among older adults. Maintaining an appropriate indoor thermal environment during winter may reduce the risk of falling among individuals who spend most of their time at home.

Objective: To examine the relationship between vegetable-first eating habits and the cognitive function in elderly patients with diabetes.

Methods: The subjects were outpatients with diabetes ≥60 years old at Ise Red Cross Hospital. A self-administered dementia checklist was used to assess mild cognitive impairment and dementia. The participants were asked to fill out a questionnaire on their vegetable-first eating habits and were classified into 4 groups: 0, 1, 2, and 3 times a day. The dependent variables were mild cognitive impairment and dementia, and the explanatory variable was vegetable-first eating habits (0 as a reference).

Results: In total, 358 patients were included in the analysis. The number of vegetable-first meals was 0 in 153 (42.7%), 1 in 48 (13.4%), 2 in 46 (12.8%), and 3 in 111 (31.1%) patients. The adjusted odds ratios for 1, 2, and 3 times of mild cognitive impairment were 0.83 (95% confidence interval [CI], 0.35-1.94; P=0.680), 0.81 (95% CI, 0.32-2.00; P=0.653), and 0.37 (95% CI, 0.17-0.81; P=0.014), respectively. However, there was no significant association between vegetable-first eating habits and dementia.

Conclusion: In elderly patients with diabetes, a vegetable-first eating habit at each meal was associated with a decreased risk of mild cognitive impairment.

Objective: To examine the relationship between difficulties experienced by family in supporting elderly patients with diabetes and these patients' higher-level functions.

Methods: The subjects were outpatients with diabetes ≥65 years old at Ise Red Cross Hospital and their family members. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) was used to assess patients' higher-level functions. The Japanese version of the Diabetes Caregiver Activity and Support Scale (D-CASS-J) was used to measure difficulties experienced by family in supporting elderly patients with diabetes. Using a multiple regression analysis with TMIG-IC scores (instrumental ADL, intellectual activity, and social participation) as the dependent variable and D-CASS-J scores (based on the highest scoring Q1 group among the three quartiles of D-CASS-J scores) as the explanatory variables, standardized regression coefficients (β) for higher-level functions on the family's perceived support difficulties were calculated.

Results: In total, 429 patients (254 male patients and 175 female patients) were included in the analysis. For male patients, the adjusted beta values for TMIG-IC scores in Q2 and Q3 were -0.039 (P=0.649) and -0.352 (P<0.001), respectively, and the adjusted beta values for the instrumental ADL scores were -0.064 (P=0.455), -0.192 (P=0.047), -0.090 (P=0.375), and -0.360 (P=0.002) for the Intellectually Active scores, respectively, and the adjusted beta for social role scores were 0.054 (P=0.581) and -0.261 (P=0.019), respectively. However, there was no association between the patients' higher-level functions and family support difficulties among female patients.

Conclusions: Difficulty experienced by the family in supporting elderly male patients with diabetes is associated with reduced higher-level functioning.
