Original Contributions



Despite the efficacy of bariatric surgery in adolescents and the increasing rates of adolescent obesity, the use of bariatric surgery remains low. Treatment cost and length of stay (LOS) could be influencing the utilization of bariatric surgery.


We used the Kids’ Inpatient Database (KID) from 2006, 2009, and 2012. Adolescents with a primary diagnosis of obesity who underwent bariatric surgery were included. Multinomial logistic and linear regression modeling was used to determine the association of the predictor variables with type of procedure and treatment cost and LOS, respectively.


We identified 1799 adolescents who underwent bariatric surgery. The majority of the subjects were female (77%) and White (60%). The most commonly performed procedure was Roux-en-Y gastric bypass (56%). Race, region, hospital teaching status, and hospital ownership affected the type of procedure performed. Self-pay patients were less likely to undergo Roux-en-Y gastric bypass (RYGB) than sleeve gastrectomy (SG) when compared to patients with private insurance. Teaching hospitals were less likely to perform RYGB or AGB than SG when compared to non-teaching hospitals. Treatment cost was significantly affected by income, teaching hospital status, hospital size, and surgery type. LOS was affected by income quartile, region, and surgery type.


Socioeconomic and demographic factors as well as hospital characteristics affect not only the LOS and treatment cost, but also the type of bariatric surgery performed in adolescents. Identifying and understanding the factors influencing procedure choice, treatment cost, and LOS can improve care and healthcare resource utilization.
