The study of the comorbidity between disordered eating and substance use in middle and high school samples tended to focus on the association between attitudes toward eating, weight, and shape and tobacco smoking, alcohol drinking, and marijuana use (Field et al., 2002). Nonetheless, several school-based studies have also reported on associations between tobacco smoking, alcohol drinking, and marijuana use in relation to bingeing, purging and dieting behaviors (Lock et al., 2001 and Tomori et al., 2001). However, only a few investigations have included a broader range of substance classes while investigating associations between disordered eating attitudes and behaviors and substance use in school-based studies (Von Ranson et al., 2002). Tomori et al. (2001) found an association between binge eating, with compensatory behaviors, and the use of alcohol as well as one or more of a list of licit and illicit drugs, while Von Ranson et al. (2002) found an association between the revised EDI subscales of Binge Eating, Body Dissatisfaction, and Compensating Behaviors, and the use of a wide range of illicit drugs.There are a small number of studies that have examined the relationship between problematic eating patterns and substance use in university samples (Anderson et al., 2005, Dunn et al., 2002, Krahn et al., 2005, Saules et al., 2004,). Lastly, as this study was conducted in a young university sample, future studies could include participants from different age groups in their investigations to evaluate whether age is an important factor when considering associations between disordered eating and the use of particular substances classes.
