نبذة مختصرة : Background Obstructive sleep apnea (OSA) has a high prevalence, and it has been shown to be an independent risk factor for various diseases. Therefore, it is important to strengthen screening for population at highrisk of OSA. OSA patients are prone to combine with lipid metabolism disorders, but it remains unclear whether the atherogenic index of plasma (AIP), visceral adiposity index (VAI), lipid accumulation product (LAP), cardiometabolic index (CMI), and Chinese visceral adiposity index (CVAI), which are used asmetabolic indexes, can be used to predict OSA. Objective To analyze the correlation between metabolic indexes and OSA, and evaluate the predictive efficacy of each metabolic index through a case-control study. Methods A total of 2 968 inpatients with suspected OSA and aged ≥18 years who completed polysomnography (PSG) in the First Affiliated Hospital of Xinjiang Medical University from March 2017 to June 2022 were selected, with 2 850 patients finally included based on the inclusion and exclusion criteria and divided into the OSA group 〔apnea-hypopnea index (AHI) ≥5 times/h, n=2 193〕 and non-OSA group (AHI0.05), but AIP and CVAI were associated with OSA (P
