To investigate the impact of different levels of cardiorespiratory fitness on the occurrence of stroke.
This study was based on the Kailun cohort study, which included a total of 37 547 participants, followed up until December 31, 2019.Cardiorespiratory fitness (Estimated cardiorespiratory fitness, eCRF) was estimated using a non-exercise algorithm, and the average eCRF values from measurements taken in 2006, 2008, and 2010 were calculated, standardized, and grouped according to gender-specific tertiles. Cox regression models were employed to explore the relationship between varying levels of eCRF and the incidence of stroke and its subtypes.
During a median follow-up of 9.05 (8.67, 9.33) years, a total of 2 100 cases of stroke (5.59%) were observed, including 1 899 (5.06%) ischemic strokes and 226 (0.60%) hemorrhagic strokes. After adjusting for confounding factors, compared to the low average eCRF group, the high eCRF group exhibited a 28% reduction in stroke risk (HR=0.72, 95%CI: 0.62-0.82), a 23% reduction in ischemic stroke risk (HR=0.77, 95%CI: 0.67-0.89), and a 40% reduction in hemorrhagic stroke risk (HR=0.60, 95%CI: 0.39-0.91).
Higher levels of cardiorespiratory fitness can reduce the risk of stroke and its subtypes.
