Posttraumatic stress disorder (PTSD) and eating pathology are frequently comorbid, and both are independent risk factors for various medical conditions. Using population‐based data collected as part of the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC‐III; N = 36,309), the primary objectives of this study were to (a) identify eating pathology classes among PTSD and (b) investigate associations between maladaptive eating and medical conditions among PTSD. Using the Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS–5), we assessed PTSD and maladaptive eating symptoms in accordance with the DSM‐5 . We used a latent class analysis to identify maladaptive eating typologies among adults with lifetime PTSD ( n = 2,339; 6.1%) and multivariable logistic regression models to examine associations between each of the six emergent maladaptive eating typologies and medical conditions. Results revealed that over 40% of individuals with PTSD endorsed indicators of maladaptive eating. In addition, each maladaptive eating typology among PTSD was significantly associated with unique sociodemographic characteristics and increased odds of medical conditions relative to no PTSD and no eating disorder, adjusted odds ratios ( AOR s) = 1.34–6.55, and PTSD with no eating psychopathology, AOR s = 1.43–5.11. Results of this study provide a better understanding of maladaptive eating in adults with PTSD and potential medical sequelae. Results indicate maladaptive eating may be an important mechanism in the association between PTSD and medical conditions, which may inform targeted interventions among individuals with these comorbidities.
