Prof. Rebecca Klatzkin and Student Researchers Shed Light on Binge Eating

This is National Eating Disorders Awareness Week, and Dr. Rebecca Klatzkin, assistant professor of psychology, has published her research on binge eating in Physiology and Behavior. Co-authors are Rhodes students Sierra Gaffney ’15, Kathryn Cyrus ’15 and Elizabeth Bigus ’14.

The title of the article is “Binge Eating Disorder and Obesity: Preliminary Evidence for Distinct Cardiovascular and Psychological Phenotypes,” and in the research, obese women with binge eating disorder (BED) were compared to obese and normal weight non-BED women.

Obese BED group reported greater depression, perceived stress, and eating psychopathology as well as showed greater blood pressure, negative affect, and anxiety irrespective of stress task. Stress-induced change in hunger was associated with cardiovascular measures in obese BED only.

Results indicate that BED and obesity are distinct in terms of psychological and physiological stress-related factors. Read more.
