Whether patients with OSA have a higher risk of prediabetes/diabetes remains unclear. We aimed to carry out a meta-analysis of published studies to evaluate the relationships between OSA and prediabetes and diabetes, and the impact of the severity of OSA on diabetes.<h4>Materials and methods</h4>The PubMed, EMBASE and Cochrane databases were searched from January 2011 to July 2021. The associations between OSA and impaired fasting glucose, impaired glucose tolerance, impaired glucose regulation and diabetes mellitus were analyzed. We estimated the pooled odds ratios using fixed or random effects models. We included 25 studies comprising a total of 154,948 patients with OSA and risk factors for pJournal of diabetes investigationObstructive sleep apnea, prediabetes and progression of type 2 diabetes: A systematic review and meta-analysis.PMC934088381970085921632003317ZXMFSY00080Wang CTan JMiao YZhang QfalseObstructive sleep apnea, prediabetes and progression of type 2 diabetes: A systematic review and meta-analysis.<h4>Aims/introduction</h4>Obstructive sleep apnea (OSA) is related to prediabetes and diabetes.
