Objective Measures of Physical Activity and Frailty in Ambulatory Adults Aged 85-89 Years in Kawasaki, Japan: A Cross-sectional Study.
Background: While physical activity (PA) can reduce physical frailty, the specific intensity and duration of PA required to prevent frailty are yet to be defined.
Objectives: This study aimed to investigate the relationship between objectively measured PA or sedentary behavior (SB) and physical frailty and to explore the theoretical effect of replacing SB with different intensities of PA on the risk of frailty.
Design: Cross-sectional study.
Setting: Community-based assessments.
Participants: Independently living adults aged 85-89 years participating in the Kawasaki Aging and Wellbeing Project.
Measurements: PA was measured using a triaxial accelerometer for a minimum of 10 h per day over a minimum of 3 days. Physical frailty was measured using the revised Japanese version of the Cardiovascular Health Study criteria. Physical frailty was classified as non-frail, pre-frail, and frail. The relationship between PA and frailty was assessed using analysis of covariance. The effect of replacing SB with light-intensity PA (LPA) or moderate-to-vigorous-intensity PA (MVPA) on the risk of frailty was estimated using multinomial logistic regression and an isotemporal substitution model.
Results: The analysis included 1004 participants (503 men and 501 women) of whom 242 were classified as frail. The mean step count, MVPA, and LPA were lower, and SB was higher in the frail group than in the non-frail group. SB replacement with MVPA for 10 min/day was associated with a significantly lower odds of frailty (odds ratio [95% confidence interval]: pre-frail men, 0.86 [0.77, 0.96]; frail men, 0.70 [0.60, 0.83]; pre-frail women, 0.77 [0.66, 0.90], frail women, 0.59 [0.47, 0.75]). SB replacement with LPA was not significantly associated with frailty odds in men or women.
Conclusions: Replacing 10 min of SB with MVPA was associated with lower risk of frailty in adults aged 85-89 years. These findings require confirmation in longitudinal and intervention studies.
期刊介绍：
The Journal of Frailty & Aging is a peer-reviewed international journal aimed at presenting articles that are related to research in the area of aging and age-related (sub)clinical conditions. In particular, the journal publishes high-quality papers describing and discussing social, biological, and clinical features underlying the onset and development of frailty in older persons. The Journal of Frailty & Aging is composed by five different sections: - Biology of frailty and aging In this section, the journal presents reports from preclinical studies and experiences focused at identifying, describing, and understanding the subclinical pathophysiological mechanisms at the basis of frailty and aging. - Physical frailty and age-related body composition modifications Studies exploring the physical and functional components of frailty are contained in this section. Moreover, since body composition plays a major role in determining physical frailty and, at the same time, represents the most evident feature of the aging process, special attention is given to studies focused on sarcopenia and obesity at older age. - Neurosciences of frailty and aging The section presents results from studies exploring the cognitive and neurological aspects of frailty and age-related conditions. In particular, papers on neurodegenerative conditions of advanced age are welcomed. - Frailty and aging in clinical practice and public health This journal’s section is devoted at presenting studies on clinical issues of frailty and age-related conditions. This multidisciplinary section particularly welcomes reports from clinicians coming from different backgrounds and specialties dealing with the heterogeneous clinical manifestations of advanced age. Moreover, this part of the journal also contains reports on frailty- and age-related social and public health issues. - Clinical trials and therapeutics This final section contains all the manuscripts presenting data on (pharmacological and non-pharmacological) interventions aimed at preventing, delaying, or treating frailty and age-related conditions.The Journal of Frailty & Aging is a quarterly publication of original papers, review articles, case reports, controversies, letters to the Editor, and book reviews. Manuscripts will be evaluated by the editorial staff and, if suitable, by expert reviewers assigned by the editors. The journal particularly welcomes papers by researchers from different backgrounds and specialities who may want to share their views and experiences on the common themes of frailty and aging.The abstracting and indexing of the Journal of Frailty & Aging is covered by MEDLINE (approval by the National Library of Medicine in February 2016).
