Association of physical frailty with incidence and life expectancy of chronic obstructive pulmonary disease: a population-based cohort study.
BACKGROUND
The bidirectional relationship between frailty and chronic obstructive pulmonary disease (COPD) is documented. However, longitudinal studies examining the combined effects of genetic predisposition and preserved ratio impaired spirometry (PRISm) on frailty in COPD development are lacking.
RESEARCH QUESTION
What is the association between physical frailty and the incidence and mortality of COPD, and how do genetic predisposition and PRISm modify this association?
STUDY DESIGN AND METHODS
We included 412,351 adults without COPD (mean age 56.1±8.1 years, 44.3% male) and 60,584 COPD patients (mean age 59.2±7.4 years, 55.1% male) at baseline in the UK Biobank cohort. Frailty phenotypes were assessed using five components, including weight loss, exhaustion, low physical activity, slow gait speed, and low grip strength. Cox proportional hazards regression models were employed to evaluate the association of genetic predisposition, PRISm, and frailty with COPD development. Life expectancy reductions due to frailty were estimated using life table methods in COPD patients.
RESULTS
During a median follow-up of 13.5 years, 10,695 incident COPD cases were recorded. In the multivariable-adjusted model, frailty and prefrailty were significantly associated with an increased risk of COPD (HR 2.21, 95% CI: 2.06-2.37 for frailty; HR 1.45, 95% CI: 1.39-1.51 for prefrailty). Significant interactions were observed between genetic predisposition and frailty (Pinteraction=0.0252), as well as between PRISm and frailty (Pinteraction=0.0027), in the development of COPD. Among patients with COPD at age 45, frailty was associated with a reduction in life expectancy of 8.49 years for males and 7.67 years for females, while prefrailty was associated with reductions of 3.27 and 2.78 years, respectively, compared to their non-frail counterparts.
INTERPRETATION
Frailty and prefrailty increase COPD risk and are linked to reduced life expectancy in patients with COPD, highlighting the need for early detection and management of frailty in COPD prevention and treatment strategies.
