Abstract
Background: Fatigue negatively impacts health outcomes but its association with physical function across the adulthood remains unclear.
Objectives: This study described self-reported fatigue levels across age and sex categories, investigated the associations between fatigue and physical functions, and examined whether age and sex moderated their associations.
Design: Cross-sectional design.
Setting: Community.
Participants: Nine hundred sixteen participants aged 20-100 years in the observational INSPIRE-T cohort study.
Measurements: Participants were classified into four age categories. Fatigue was assessed using the Patient-Reported Outcomes Measurement Information System (Short Form v1.0 - Fatigue 8a) and physical function was assessed by handgrip strength (HGS, Kg), usual gait speed (UGS, m/s), both 5-repetition (5CR, s) and 30-sec chair rise tests (30sCR, times), isokinetic knee extension strength (IKES, N m), and maximum oxygen consumption (V̇O2 max, ml/kg/min). Multiple linear regressions were performed to examine the associations between fatigue and the physical function outcomes (all square-root-transformed). Interactions of fatigue with age and sex were considered.
Results: Fatigue levels were the highest in people 75+ years. Women had a higher fatigue level than men. Fatigue was significantly associated with decreasing performance in UGS, HGS, 5CR, and 30sCR but not in IKES and V̇O2 max. Interaction analyses revealed that fatigue was associated with reduced UGS as people age (Fatigue × age: B = -0.002, 95% confidence interval = -0.003, -0.001). Sex did not moderate the association between fatigue and physical function.
Conclusions: Our study indicated that fatigue was negatively associated with several components of physical function. Although sex did not moderate the relationship between fatigue and physical function, the association between fatigue and low UGS was more pronounced with increasing age.

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).
