|Abstract:||BACKGROUND: Frailty is associated with chronic inflammation, which may be modified by aspirin. The purpose of this study was to determine whether low dose aspirin reduces incident frailty in healthy older adult participants of the ASPirin in Reducing Events in the Elderly (ASPREE) trial. METHODS: In the U.S and Australia, 19,114 community-dwelling individuals aged ≥70 years (U.S minorities ≥65 years) and free of overt cardiovascular disease, persistent physical disability, and dementia, were enrolled in ASPREE, a double-blind, placebo-controlled trial of 100mg daily aspirin versus placebo. Frailty, a pre-specified study endpoint, was defined according to a modified Fried frailty definition (Fried frailty) and the frailty index based on the deficit accumulation model (frailty index). Competing risk Cox proportional hazards models were used to compare time to incident frailty by aspirin versus placebo. Sensitivity analysis was conducted to include frailty data with and without imputation of missing data. RESULTS: Over a median 4.7 years, 2252 participants developed incident Fried frailty, and 4451 had incident frailty according to the frailty index. Compared with placebo, aspirin treatment did not alter the risk of incident frailty (Fried frailty HR: 1.04, 95% CI 0.96-1.13; frailty index HR: 1.03, 95% CI 0.97-1.09). The proportion of individuals classified as frail, and the trajectory in continuous frailty scores over time, were not different between the aspirin and placebo treatment groups. The results were consistent across a series of subgroups. CONCLUSIONS: Low dose aspirin use in healthy older adults when initiated in older ages does not reduce risk of incident frailty or the trajectory of frailty.|
