Background Obesity is a significant risk factor for adverse postoperative outcomes, including impaired wound healing. This study aimed to investigate the association between the Body Roundness Index (BRI) and impaired wound healing following thoracic surgery. Methods This study included 387 patients who underwent thoracic surgery at Tongji Hospital in Wuhan between October 2024 and January 2025. Wound healing was assessed 30 days postoperatively. Logistic regression and propensity score matching (PSM) analyses were performed to evaluate the relationship between BRI and impaired wound healing, with subgroup analyses conducted to further explore this association.
