1696 general population (780 females, 916 males)
- Prevalence higher in athletes than general population. More common in female athletes and general population.

- Compare prevalence of disordered eating between female college athletes and no-athletes and explore emotion regulation as a potential mediator for the link between participation in athletics and disordered eating.
- 527 American college students. 151 athletes, 376 non-athletes
- The non-athletes had a higher prevalence of disordered eating compared to the athletes. Greater difficulties with regulating emotions were reported with non-athletes.

- The aim of this study was to examine the association between a history of childhood obesity and dieting behaviors with the development of eating disorders later in life
- Consisted of 537 outpatients from treatment centers between the ages of 16-60 year olds
- The results showed that childhood obesity was associated with the development of eating disorders later in life
(Sala, Brosof and
- The aim of this study was to examine the relationships between repetitive negative thinking and subsequent eating disorder behaviors and vice-versa using ecological momentary assessment
- 66 participants who were recently treated in eating disorder treatment clinics
- Results showed that higher momentary repetitive negative thinking predicted higher subsequent weighing and body checking
(Stanford and Lembery, 2012)
- The objectives of this study were to measure ED's in men by developing the Eating Disorder Assessment for Men (EDAM)
- 108 clinical subjects participated. 78 males, 30 females
- EDAM developed to predict ones risk of developing/having an ED
