Hence, it is imperative to determine the amplitude and to identify the risk factors of eating disorders (ED) to enable effective interventions.
Aim: To assess prevalence and associated factors of (ED) among health occupation students in the university of Monastir during 2013.

The prevalence of ED according to SCOFF questionnaire was 35%; 95% CI [32.0-38.5]. It was higher among female (39.8; 95% CI [35.8-43.7]) compared to male (24.3; 95% CI [18.8-29.7]) with a statistically significant difference (p<10-3). The risk factors associated independently with an eating disorder were "Previous dieting" (aOR=4.13; 95% CI [2.79-6.12]),"Sex" (aOR=1.77. 95% CI [1.13-2.77]) and "Repeat a year" (aOR=1.76; 95% CI [1.09-2.85]).
