Sexual and gender minority subpopulations are often under-examined in eating disorders research, creating a significant gap in the literature. Sexual and gender minority populations are comprised of distinct subgroups with specific health concerns. The purpose of this study is to investigate the prevalence of self-reported eating disorder (ED; anorexia nervosa and bulimia nervosa) diagnoses and two disordered eating behaviors (DEB; purging and diet pill use) among a nationally based sample of sexual and gender minority college students using the Fall 2015 version of the National College Health Assessment (ACHA-NCHA IIc). Among those subpopulations that showed elevated odds of ED or DEB, cisgender bisexual females reported significantly higher odds of purging to lose weight within the last 30 days when compared to cisgender heterosexual females (OR= 1.986, CI= 1.419-2.780) and cisgender queer females reported elevated odds of self-reported bulimia diagnosis within the past 12 months when compared to cisgender heterosexual females (OR= 5.259, CI= 1.463-18.899). Cisgender asexual males reported significantly lower odds of using diet pills to lose weight (OR= 0.257, CI= 0.082-0.807) when compared to cisgender heterosexual females. This analysis was one of the first instances of examining ED and DEB among a very diverse range of sexual and gender minority populations using the National College Health Assessment. Exploring sexual and gender minority subpopulations independently facilitates more appropriate approaches to addressing eating disorder concerns among these high risk populations. In addition, future research should address the complex factors associated with ED and DEB among sexual and gender minority college students in order to tailor effective intervention strategies.
