Gender differences in binge eating and behavioral correlates among college students

The purpose of this study was to investigate gender differences in binge eating and associated behavioral correlates in college students.

A webbased survey was conducted with 2073 students (mean age 19.8 yr; range 18-23 yr). Multiple logistic regression was used to calculate odds ratios and 95% confidence intervals for the factors associated with binge eating.

Twenty-nine percent of students reported recent bingeing. Factors associated with binge eating included being female, having a higher body mass index, current tobacco use, and exercising to lose weight. Women were more likely to binge eat (73.8%; χ(2)=32.3; p≤0.001), report loss of control (45%; χ(2)=16.3; p≤0.001), self induced vomiting (20.7%; χ(2)=15.9; p≤0.001), and laxative use (6.7%; χ(2)=8.93; p≤0.001).

Results generated from this study suggest that gender-disparate behaviors are potential targets for future tailored interventions.
