The Role of Ego Networks in Compulsive Exercise Behavior Among a Sample of College Sorority Women.

BACKGROUND: Compulsive exercise (CE) is a harmful form of exercise that elevates the risk of developing/sustaining clinical eating disorders. College-aged sorority women are especially prone to CE. Due to the pronounced impact social relationships have on college students' behavior, this study aims to examine personal networks and CE among a sample of sorority women through an egocentric network analysis.

METHODS: A total of 204 women in a sorority from a large, private university in the southeastern United States completed a cross-sectional survey in spring 2015. Descriptive and regression analyses were conducted on demographic, attribute, and ego network data.

RESULTS: Relationships with siblings, significant others, and roommates were protective against CE in this sample. Conversely, body dissatisfaction and exercise frequency predicted CE.

CONCLUSIONS: Findings suggest that social relationships can impact CE behaviors in this sample. Along with promoting body satisfaction and healthy exercise, public health efforts should focus on facilitating close interpersonal relationships, especially between sorority women and siblings, significant others, and roommates.
