  • Evaluate the efficacy and safety outcomes of bariatric surgery in adolescents relative to adults, using a prospective, observational cohort design. [ Time Frame: Initially funded in 2006 then refunded with extension to 2021. ]
    Enrolled 242 participants by 12/31/11. Continued participation of initial cohort with additional participants with specified conditions to enroll between 2017-2021. To compare risks and benefits of gastric bypass and sleeve gastrectomy procedures in individuals undergoing these procedures as adolescents.
  • Assessment of long term safety by assessment of bone mineral density, micronutrient status, and continued collection of detailed data characterizing pregnancies, childbirth, abdominal operations, and deaths. [ Time Frame: 2016-2021 ]
    To identify complications to be expected for adolescents and adults undergoing bariatric surgery, specifically short and long-term surgical, medical and nutritional bone density, and risk taking behaviors.

Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) Adolescent Bariatrics: Assessing Health Benefits and Risk
Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) Research Project
The five Teen-LABS clinical centers use standardized techniques to assess the short and longer-term safety and efficacy of bariatric surgery in adolescents compared to adults.

The goal of Teen-LABS is to facilitate coordinated clinical, epidemiological and behavioral research in the field of adolescent bariatric surgery, through the cooperative development of common clinical protocols and a bariatric surgery database that will collect information from participating clinical centers performing bariatric surgery on teenagers.

Teen-LABS will help pool the necessary clinical expertise and administrative resources to facilitate the conduct of multiple clinical studies in a timely, efficient manner. Also, the use of standardized definitions, shared clinical protocols and data collection instruments will enhance investigators' ability to provide meaningful evidence-based recommendations for patient evaluation, selection and follow-up care.

In addition to investigating surgical outcomes, another broader goal of Teen-LABS is to better understand the etiology, pathophysiology, and behavioral aspects of severe obesity in youth and how this condition affects human beings over time.

In the 3rd five year cycle of funding for this project, several additional long-term research aims have been added, all in general alignment with the original aims of the project to assess efficacy and safety of bariatric surgery performed in adolescent years.
