BACKGROUND: Higher body mass index (BMI) has been associated with @entity260 in @entity348 ( @entity348 ) and @entity572 ( @entity572 ). However, the association of incremental increases of BMI and its effects on @entity260 has not been well studied. We hypothesize that there is a BMI cutoff at which there is a significant increase of the risk of @entity260 . METHODS: We studied the American College of Surgeons National Surgical Quality Improvement Program from 2006 to 2013. The final cohort included 77,785 primary @entity348 and 49,475 primary @entity572 subjects, respectively. @entity1 were separated into 7 groups based on BMI (18.5-24.9 kg/m(2), 25.0-29.9 kg/m(2), 30.0-34.9 kg/m(2), 35.0-39.9 kg/m(2), 40.0-44.9 kg/m(2), 45.0-49.9 kg/m(2), and >50.0 kg/m(2)). We analyzed data on five 30-day composite complication variables, including any @entity532 , @entity2737 , @entity299 . RESULTS: The odds ratio for 4 (any @entity532 , @entity2737 , and systemic infection) of 5 composite complications started to increase exponentially once BMI reached 45.0 kg/m(2) or higher in @entity348 . Similarly, the odds ratio in 3 (any complication, @entity281 ) of 5 composite complications showed similar trends in @entity572 @entity1 . These findings were further confirmed with propensity score matching and entropy balancing. CONCLUSIONS: Our study suggested that there was a positive correlation between BMI and incidences of 30-day @entity260 in both @entity348 and @entity572 . The odds of complications increased dramatically once BMI reached 45.0 kg/m(2).

Body Mass Index More Than 45 kg/m(2) as a Cutoff Point Is Associated With Dramatically Increased XXXX in Total Knee Arthroplasty and Total Hip Arthroplasty.
