Disordered eating and weight gain are problematic for college women. However, the college years also provide an ideal opportunity to engender healthy habits and increase support for such behaviors. Support for Healthy Eating and Exercise (SHEE) is a 5-week program designed to prevent both eating disorders and weight gain in university women. The group based intervention combines Appetite Awareness Training (AAT), physical activity, and social support as a way to increase healthy eating and physical activity. Ninety women concerned about weight gain were recruited for the SHEE program and were randomly assigned to either the treatment group or a waitlist control group. Based on body mass index and self-report symptomatology, the SHEE program attracted women at-risk for obesity as well as for eating disorders. Following the 5-week intervention, participants reported increased interoceptive awareness, weight management self-efficacy, and normal eating and decreased disordered eating compared to individuals in the waitlist control condition. There were no significant differences between the groups on physical activity, social support for health related behaviors, or body mass index. Results indicate that reconnecting with internal signals of hunger and fullness and learning to use these physiological cues to guide eating decisions was associated with improvements. Long-term follow-up is needed to determine if the intervention effects persist over time as well as to describe the extent to which this intervention ultimately impacts weight gain or escalation of eating disordered symptoms.
