The Journal of Frailty & Aging (JFA) is a fully digital, gold open-access, peer-reviewed international journal dedicated to advancing research in aging and age-related (sub)clinical conditions. The journal focuses on publishing high-quality articles that explore the social, biological, and clinical factors underlying the maintenance and decline of intrinsic capacity, as well as the onset and progression of frailty, in older adults.

JFA is organized into five distinct sections:

1. Biology of Intrinsic Capacity, Frailty, and Aging
   This section features reports from preclinical studies and research aimed at identifying, describing, and understanding the subclinical pathophysiological mechanisms that govern intrinsic capacity trajectories, frailty development, and the biology of aging.
   
2. Intrinsic Capacity, Physical Frailty, and Age-Related Body Composition Modifications
   Articles in this section examine the physical and functional dimensions of intrinsic capacity particularly the locomotion and vitality domains alongside the clinical syndrome of physical frailty, with special attention to body composition as a hallmark of aging. Studies on sarcopenia and obesity in older adults are especially welcome.
   
3. Neurosciences of Frailty and Aging
   This section highlights research on the cognitive and neurological dimensions of intrinsic capacity decline and frailty, with particular emphasis on neurodegenerative disorders affecting older populations.
   
4. Intrinsic Capacity, Frailty, and Aging in Clinical Practice and Public Health
   Dedicated to clinical and multidisciplinary perspectives, this section includes studies addressing the assessment and management of intrinsic capacity and frailty across diverse settings in advanced age. It also covers the broader social and public health implications of these conditions, offering valuable insights from clinicians across various specialties.
   
5. Clinical Trials and Therapeutics
   This section includes manuscripts presenting data on pharmacological and non-pharmacological interventions designed to preserve or optimize intrinsic capacity, and to prevent, delay, or treat frailty and other age-related conditions.

The Journal of Frailty & Aging welcomes a range of submission types - including original research papers, review articles, case reports, controversies, letters to the Editor, and book reviews - addressing intrinsic capacity, frailty, and aging. Manuscripts are evaluated by the editorial team and, where appropriate, undergo peer review by expert reviewers selected by the editors. JFA particularly encourages contributions from researchers and clinicians across diverse backgrounds and specialties, fostering a multidisciplinary approach to healthy aging, intrinsic capacity maintenance, and frailty prevention.

The Journal of Frailty & Aging is indexed in Directory of Open Access Journals (DOAJ), Medline, PubMed Central (PMC), Web of Science (ESCI), and Scopus.
