This study characterised the cardiometabolic burden, comorbidity, and frailty of adults undergoing laparoscopic sleeve gastrectomy (LSG), with comparisons according to sex and hospital setting.</p><p><strong>Method: </strong>A population-based cohort study was conducted using statewide administrative hospital data from all public and private hospitals in New South Wales, Australia, between 1 July 2017 and 30 June 2022.
