Abstract

Abstract: Objective: To investigate associations between reported eating disorder (ED) diagnosis and substance use disorder (SUD) diagnosis, substance misuse, and illicit drug use among US college students. Method: Data consisting of n = 414, 299 students' responses to the National College Health Assessment survey conducted by the American College Health Association between fall 2015 and spring 2019 were utilized for this study. Unadjusted and adjusted odds ratios were used to determine the association of reported ED diagnosis with reported SUD diagnosis, misuse of cigarettes, e‐cigarettes, alcohol, marijuana, cocaine/methamphetamine, sedatives, hallucinogens, opiates, inhalants, MDMA, and other club drugs, as well as illicit use of prescription pain killers, prescription sedatives, and prescription stimulants. A sensitivity analysis investigating associations between reported anorexia nervosa (AN), bulimia nervosa (BN), and each substance use outcome was also conducted. Results: Among all in our analytic cohort, 7.15% reported receiving an ED diagnosis or being treated for an ED in the last 12 months. Students with ED indications were significantly more likely to report each of the substance use outcomes investigated in this study, including SUD diagnosis (aOR: 7.43; 95% CI: 6.98, 7.92; p < .0001), opiate misuse (aOR: 8.35; 95% CI: 7.38, 9.45; p < .0001), and misuse of other club drugs (aOR: 10.37; 95% CI: 9.10, 11.81; p < .0001) than peers without reported EDs. Both AN and BN were associated with an increased likelihood of SUD diagnosis. Discussion: These findings demonstrate strong associations between EDs and the most extensive list of substance use outcomes explored in the context of college setting ED research to date.
