Developmental changes in fat talk to avoid peer rejection in Japanese girls and young women.

"Fat talk" refers to conversations focused on body disparagement. We examined developmental changes in fat talk to avoid social rejection and the mediating role of fat talk between "thin-ideal" internalization and body dissatisfaction. A total of 214 high school girls and 227 college-aged women completed questionnaires assessing fat talk engagement, body dissatisfaction, thin-ideal internalization, and sensitivity to rejection.
