摘要

背景不同年龄组虚弱发展的相关因素仍不清楚:设计:13 年纵向研究:研究地点:日本群马县草津町:1706名年龄≥65岁的老年人,他们在2007年至2019年间至少完成了一次年度虚弱评估:采用基于弗里德虚弱表型标准的指数确定虚弱状态。虚弱轨迹的潜在相关因素包括生理、生物、生活方式相关因素、心理因素以及合并症:我们发现了从 65 岁到 90 岁虚弱评分的五种轨迹模式--体格健壮者(第 1 组,10.5%)、晚发虚弱者(第 2 组,16.1%)、中发虚弱者(第 3 组,25.6%;第 4 组,35.2%)和早发虚弱者(第 5 组,12.7%)。与其他组别相比,早发组在随访结束时出现脑血管疾病、骨关节疾病、营养不良、肌肉疏松症、住院、认知功能低下和吸烟的比例较高。中期发病组的相关因素在很大程度上与早期发病组重叠。与健壮组相比,晚发性虚弱组与心脏病、骨关节疾病的关联度更高:我们从一项为期 13 年的纵向研究中发现了五种虚弱轨迹模式和七种与虚弱轨迹相关的因素。针对每个年龄组提出的基于人群的有效虚弱预防策略可能有助于采取有效策略,延长老龄化、高龄化和超高龄化社区的健康预期寿命。

Frailty Trajectories and Its Associated Factors in Japanese Older Adults.

Background: Associated factors for frailty development according to age group remain unclear.

Objectives: To identify frailty score trajectories among community-dwelling older Japanese individuals and examine their associated factors.

Design: 13-year longitudinal study.

Setting: Kusatsu Town in Gunma Prefecture, Japan.

Participants: 1706 older adults aged ≥ 65 years who completed an annual frailty assessment at least once between 2007 and 2019.

Measurements: Frailty status was determined using an index based on the Fried frailty phenotype criteria. Potential associated factors for frailty trajectory included physical, biological, lifestyle-related, and psychological factors, as well as comorbidities.

Results: We identified five trajectory patterns in the frailty score from age of 65 to 90 years -individuals who were robust (Group 1, 10.5%) as well as individuals with late-onset frailty (Group 2, 16.1%), middle-onset frailty (Group 3, 25.6% and Group 4, 35.2%), and early-onset frailty (Group 5, 12.7%). Compared with the other groups, the early-onset group showed a higher prevalence of cerebrovascular diseases, bone and joint diseases, poor nutrition, sarcopenia, hospitalization, low cognitive function, and smoking at the end of follow-up. Associated factors in the middle-onset group largely overlapped with those of the early-onset group. The late-onset frailty group tended to have a higher association with heart disease and bone and joint diseases compared with the robust group.

Conclusion: Our findings from a 13-year longitudinal study identified five frailty trajectory patterns and seven associated factors for frailty trajectory. Proposed effective population-based frailty prevention strategies in each age group may contribute to effective strategies to extend healthy life expectancy in aging, aged, and super-aged communities.

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).
