Psychosocial and Behavioral Aspects of Bariatric Surgery

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) is seeking applications designed to measure psychosocial and behavioral variables in individuals undergoing bariatric surgery to understand how they predict success and risk and examine mechanisms of behavior change. The funding opportunity announcement, Psychosocial and Behavioral Aspects of Bariatric Surgery (RFA-DK-14-026), responds to the dramatic increase in the number of bariatric surgeries performed in the U.S. over the last decade, including those performed on adolescents.

This surgery has been shown to produce large sustained weight loss in many individuals. The emerging evidence also suggests that the surgery may be beneficial for treatment of type 2 diabetes and other obesity-related comorbidities. In addition, the data about the short- and long-term behavioral and psychological predictors, mechanisms are either insufficient or mixed, according to NIDDK.

The Institute is also interested in basic behavioral research to look at mechanisms by which bariatric surgical procedures may impact energy intake and physical activity through changes in such factors as experience of hunger or satiety, macronutrient, taste, ore other dietary preference, reward sensitivity, cognition, executive function, and mood. In addition, NIDDK is interested in understanding predictors of success and risk and examining mechanisms of behavior change. Research is needed that allows detailed measurement of psychosocial and behavioral variables in the targeted population before and after bariatric surgery.

Letters of intent are due March 16, 2015. Applications are due April 16, 2015.
