Aim: The present study investigated the rejuvenation of physical function in terms of walking speed and grip strength. Specifically, it examined the rejuvenation of physical functions in community-dwelling older individuals between 2006 and 2019. The study is novel, because it analyzes this by focusing on gait balance.
Methods: Data were collected from 339 participants (52 men, 287 women) in 2006, and 382 participants (83 men, 299 women) in 2019. They were categorized according to age: early-stage and late-stage groups for men, and early-stage, late-stage and latest-stage groups for women. These groups were analyzed by participants' walking speed, grip strength, Timed Up and Go test, Functional Reach test and One-Leg Standing test. The results were compared based on two factors: time (2006 to 2019) and age group.
Results: The scores for the Timed Up and Go and One-Leg Standing tests were better in 2019 than in 2006 for all age groups in both older men and women. However, improvement in walking speed was observed only in women. Additionally, the decline in physical function with age was slower for walking speed among men, and Functional Reach and One-Leg Standing tests among women.
Conclusions: The changes over this 13-year period showed that the physical function of community-dwelling older individuals was rejuvenated in terms of improved standing and walking balance. These rejuvenations will aid in preventing falls among community-dwelling older individuals. Geriatr Gerontol Int 2021; 21: 975-980.

Background: Advancements in mobile technology have paved the way for innovative interventions aimed at promoting physical activity (PA).
Objective: The main objective of this feasibility study was to assess the feasibility, usability, and acceptability of the More In Action (MIA) app, designed to promote PA among older adults. MIA offers 7 features: personalized tips, PA literacy, guided peer workouts, a community calendar, a personal activity diary, a progression monitor, and a chatbot.

The socioeconomic burden of hip fractures, the most severe osteoporotic fracture outcome, is increasing and the current clinical risk assessment lacks sensitivity. This study aimed to develop a method for improved prediction of hip fracture by incorporating measurements of bone microstructure and composition derived from high-resolution peripheral quantitative computed tomography (HR-pQCT). In a prospective cohort study of 3028 community-dwelling women aged 75 to 80, all participants answered questionnaires and underwent baseline examinations of anthropometrics and bone by dual x-ray absorptiometry (DXA) and HR-pQCT.

Manual wheelchairs can promote independence among users. However, the user's level of disability, strength, stamina, and the environmental conditions within which the wheelchair is used may limit manual wheelchair functionality. The use of power assist add-ons may mitigate these limitations and help individuals to age in place.

The outbreak of the Israel-Hamas war on October 7, 2023, has presented unprecedented challenges to older adults' mental health, including increased posttraumatic stress, anxiety, and depression. The current study examined potential war- and age-related factors associated with probable posttraumatic stress disorder (PTSD), clinical depression (probable depression), and generalized anxiety disorder (probable anxiety) among older adults during the ongoing war. Moreover, due to the continued threat of death, we examined whether death anxiety is an additional contributing factor to older adults' probable PTSD, depression, and anxiety.

Introduction: We explored which dementia risk factors in two multidomain prevention trials mediate beneficial, neutral, or counteracting effects on dementia incidence.
Methods: We pooled data from the multidomain MAPT (Multidomain Alzheimer Preventive Trial; n = 1679, up to 5-year follow-up) and preDIVA trials (Prevention of Dementia by Intensive Vascular Care; n = 3526, up to 12-year follow-up) in adults aged 70+. We used multiple mediation analysis to quantify the role of 2-year changes in body mass index, systolic blood pressure, total cholesterol, and physical activity in the intervention effects on dementia incidence.
