Abstract: Objectives: To systematically evaluate the risk factors for intraoperative hypothermia in patients undergoing laparoscopic surgery globally; and to provide information on how to prevent complications and, should they occur, how to intervene. Methods: This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO; No. CRD42024555506). We searched the following databases: PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Web of Science Core Collection, EMBASE, China National Knowledge Infrastructure (CNKI), and Wanfang. Data on risk factors for hypothermia during laparoscopic surgery were systematically collected through June 1, 2024. After evaluating references that met Newcastle–Ottawa scale (NOS) or Agency for Healthcare Research and Quality (AHRQ) inclusion criteria, we performed a meta-analysis of the extracted data using RevMan version 5.4. Results: We included 11 studies with a cumulative sample size of 3550 cases and extracted 14 risk factors. Meta-analysis results showed that age (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00–1.03; P = 0.04), total amount of intraoperative CO2 injected into the abdominal cavity > 200 L (OR, 1.5; 95% CI, 1.30–1.81; P 120 min (OR, 2.32; 95% CI, 2.03–2.65; P 150 min (OR, 1.55; 95% CI, 1.26–1.92; P 1500 mL (OR = 1.77; 95% CI, 1.48–2.12; P
