The FR-IC index demonstrated good concurrent validity for baseline disability and significant predictive validity for 1-year deterioration in disability among older outpatients. This tool may enable effective risk stratification and seamless monitoring of physical and mental capacities across the aging trajectory in clinical settings.

Aim: Evidence regarding the association between heart failure and sarcopenia in middle-aged and older community-dwelling adults is scarce. This study aimed to examine the association between NT-proBNP levels and sarcopenia among community-dwelling adults aged 40-74 years.

Methods: This cross-sectional study was conducted based on the Circulatory Risk in Communities Study, which involved 1675 Japanese residents aged 40-74 years. Serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, physical function, and lifestyle information were measured. Participants were categorized according to their NT-proBNP levels (< 55, 55-124, and ≥ 125 pg/mL). Multivariate-adjusted logistic regression models were used to calculate the odds ratios for low skeletal muscle mass, muscle strength, walking speed, maximal walking speed, and sarcopenia according to serum NT-proBNP levels.

Results: Among the analyzed participants, the prevalence was 22.6% for low skeletal muscle mass, 4.3% for low handgrip strength, 14.3% for low walking speed, 24.1% for low maximal walking speed, and 5.9% for sarcopenia. The multivariable odds ratios (95% confidence interval, p for trend) comparing the highest versus lowest groups of serum NT-proBNP levels were 1.63 (1.07-2.49, p < 0.01) for low skeletal muscle mass, 3.38 (1.70-6.73, p < 0.01) for low handgrip strength, 1.81 (0.96-3.40, p = 0.06) for low walking speed, 1.75 (1.03-2.97, p = 0.06) for low maximal walking speed, and 2.56 (1.07-6.14, p = 0.03) for sarcopenia.

Conclusions: High serum NT-proBNP levels, which are a surrogate marker for heart failure, were associated with low physical function and sarcopenia.

Aim: Preventing and mitigating frailty across physical, cognitive, social, and oral domains is vital for extending healthy life expectancy in older adults. Although apathy and depressive symptoms are reportedly associated with frailty domains, their domain-specific relationships remain unclear. This study aimed to compare the associations of apathy and depressive symptoms with frailty domains in older adults.

Methods: This cross-sectional study included 465 community-dwelling adults aged ≥ 75 years (median age, 78 years; interquartile range, 76.0-82.0; 49.7% women) from the 2024 Shimane CoHRE Study. Apathy and depressive symptoms were defined as scores of ≥ 16 on the Japanese version of the Starkstein Apathy Scale and ≥ 40 on the Self-rating Depression Scale, respectively. Frailty domains across physical, cognitive, social, and oral domains were assessed using the Questionnaire for Medical Checkup of the Old-Old. Logistic regression analyses adjusted for age, sex, and body mass index.

Results: The prevalence of apathy, depressive symptoms, and their coexistence was 30.8%, 29.9%, and 14.6%, respectively. Both apathy and depressive symptoms were significantly associated with a higher prevalence of physical frailty (lack of exercise), cognitive frailty (memory impairment), and social frailty (lack of interaction with others). Their coexistence was additionally associated with oral, physical, cognitive, and social frailty.

Conclusions: Apathy and depressive symptoms share some frailty domains but also exhibit domain-specific associations. Their coexistence may be associated with multidimensional frailty. These findings highlight the importance of assessing emotional function and tailoring frailty prevention to individual emotional profiles.

Aim: Recent studies have suggested that masticatory function may influence frailty progression. However, the relationship between posterior occlusal support and frailty remains underexplored. We aimed to evaluate the association between the loss of posterior occlusal support and frailty in a large cohort of Japanese adults.

Methods: This retrospective cohort study used data from the JMDC Claims Database. We included 386 270 individuals aged ≥ 40 years who underwent both specific health checkups and dental visits in 2016, with follow-up data available through 2020. We categorized posterior occlusal support using the Eichner classification (A, all support zones intact; B, partial support zones; C, no functional support zones). We assessed frailty annually using the claims-based frailty index (CFI) (a deficit accumulation-type frailty measure). We used generalized estimating equations to evaluate the association between occlusal support and frailty after adjusting for potential confounders.

Results: At baseline, the mean age was 49.6 (standard deviation, 7.2) years, and 47.4% of the participants were women. The prevalence of frailty was 4.9%, 9.5%, and 12.1% in the Eichner A, B, and C groups, respectively. Compared to Eichner A, the adjusted odds ratios (ORs) for frailty were 1.21 (95% confidence interval [CI], 1.13-1.30) for Eichner B and 1.39 (95% CI, 1.21-1.59) for Eichner C. This relationship was stronger among women than men.

Conclusions: Reduced posterior occlusal support is independently associated with an increased risk of frailty. These findings underscore the importance of oral health in preventing physical debilitation and suggest incorporating early dental interventions into health strategies for older populations.
