Abstract: The objective of this study was to explore the association among adverse events, body mass index (BMI), and hospital costs after colorectal cancer surgery in a country with an intermediate BMI distribution.; All colorectal cancer procedures in 29 Dutch hospitals listed in a 2010-2012 population-based database and with a BMI?>?18.5 were included (n?=?8687). Hospital costs were measured uniformly and based on time-driven activity-based costing. The BMI classification of the World Health Organization was used.; Patients in obesity classes 1 (23.6% [after risk-adjustment OR 1.245, CI 1.064-1.479, P?=?0.007]) and =2 (28.1% [after risk-adjustment OR 1.816, CI 1.382-2.388, P?
