Summary: In this study, it was found that there is a significant association between oral hypofunction and frailty, sarcopenia, and mild cognitive impairment. Frailty was associated with deterioration of swallowing function, mild cognitive impairment was associated with reduced occlusal force and decreased tongue pressure, while no independent association was found between sarcopenia and oral function.

Summary: This study examined the association between dietary inflammatory potential and probable sarcopenia among older adults. The findings suggest that adhering to a pro-inflammatory diet is associated with a higher likelihood of sarcopenia, and individuals with sarcopenia have a lower intake of anti-inflammatory nutrients.

Summary: This study investigated community participation in older adults through GPS, accelerometry, and self-reported diaries. The results showed that older adults engage in more social activities outside the home, with frequent visits to commercial locations. The combination of GPS, accelerometry, and self-report methods provided a detailed understanding of community participation in older adults.

Summary: This study found a relationship between depressive symptoms and frailty/pre-frailty in community-dwelling older adults in Japan, suggesting that physical frailty should be assessed in depressed individuals to prioritize the clinical evaluation of geriatric syndromes.

Summary: This study investigated the prevalence of sarcopenia among older Chinese adults and found that serum homocysteine levels were independently associated with sarcopenia. Additionally, female subjects and patients with hyperhomocysteinemia had a higher risk of developing sarcopenia.

Summary: This study applied machine learning to analyze gait parameters in order to distinguish low skeletal muscle mass in older adults. The results showed that stride length, hip dynamic range of motion, and trunk rotation variability were the most important gait parameters for detecting low muscle mass.

Summary: The purpose of this study was to investigate the association between moderate to vigorous physical activity (MVPA), sedentary behavior, fruit and vegetable intake, and the risk of sarcopenia among older Chinese adults. The results showed that only 32.63% of the participants met the recommendations for MVPA, sedentary behavior, and fruit and vegetable intake, and meeting these recommendations was associated with a lower risk of sarcopenia.

Summary: The updated definition of sarcopenia by EWGSOP2 includes low muscle mass and quality, as well as poor physical performance as indicative of severe sarcopenia. The study found that individuals with any form of sarcopenia were at a higher risk of disability, with severe sarcopenia increasing the risk further. Grip strength and walking speed were negatively correlated with disability incidence.

Summary: The study aimed to investigate the prevalence of social frailty among older adults in a rural Japanese community and factors associated with social frailty status. The results showed that social frailty is increasing in Japanese rural areas, with social prefrailty potentially being associated with attentional function and GDS-15 scores.

Summary: This study aimed to clarify the impact of social frailty in community-dwelling older adults during the COVID-19 pandemic. The findings suggest that the implementation of stay-at-home orders and increased depressive symptoms may contribute to the increase in social frailty among older individuals.

Summary: Social participation is associated with a lower risk of incident disability and mortality in both healthy and frail older adults. This study suggests that frail older adults should be encouraged to engage in various social activities to reduce the risk of subsequent disability and mortality.

Summary: Subjective cognitive decline (SCD) in older adults is associated with an increased risk of dementia, but the underlying mechanisms are not well understood. This study found that older adults with SCD have more modifiable protective factors against dementia and a lower risk of developing objective cognitive decline. These findings highlight the importance of addressing modifiable factors in preventing dementia.

Summary: This study aimed to determine whether osteoporosis, osteopenia, and sarcopenia identified by simplified instruments are associated with the future incidence of disability and mortality. The results showed that osteosarcopenia was associated with an increased risk of disability and mortality. Further research is needed to implement these findings in community health activities.
