Objective: Comorbidity between substance use disorders and eating disorders is common and related to severity of psychopathology. Parents' eating disorder or substance use disorder have been examined independently and appear to be related to psychopathology in their children. However, no prior work has examined whether co-occurring substance use and eating disorder behaviors in parents relate to eating-disorder psychopathology and weight in their children.
Method: Participants (N = 435) were parents who completed an online cross-sectional survey. Parents reported their personal substance use and eating-disorder behaviors. Relationships between parental substance use (SUD), parental binge eating (ED), and co-occurring parental substance use and binge eating (SUDxED) with child eating-disorder psychopathology and weight were examined using linear regression. Parent age and sex, child age and sex, parent impulsivity and parent depression scores were included as covariates in analyses.
Results: Greater severity of co-occurring parental SUDxED behavior was associated with greater child eating-related psychopathology, including child binge eating and child purging. Additionally, greater parental binge eating (ED) alone was associated with greater child binge eating and overeating. Parental SUD and/or ED behavior were not related to child weight. Child age did not moderate relationships between parent SUDxED behaviors and child binge eating or overeating.
Discussion: Overall, parents with greater co-occurring substance use and eating disorder behaviors had children with more severe eating-disorder psychopathology. Clinicians working with families, and those seeking to prevent pediatric eating-related problems, should consider assessing and addressing parents' psychopathology to improve prevention and treatment efforts.

Background: Avoidant/restrictive food intake disorder (ARFID) may result in significant medical sequelae. Compared to youth with eating disorders like anorexia nervosa (AN), youth with ARFID tend to be younger and are more likely to be male. We aim to describe sex differences in clinical characteristics of youth hospitalized for medical complications of ARFID and compare their characteristics with youth hospitalized for anorexia nervosa.

: Binge eating (BE) is associated with physical and psychological consequences, such as obesity and reduced quality of life. The relationship between binge eating and childhood experiences of interpersonal trauma has been explored, yet few studies focus on the processes that may explain this association. In this regard, some personality traits and maladaptive cognitive-emotional regulation may help explain this relationship, as they have been associated, respectively, with BE and childhood interpersonal trauma.

: Recent research has increasingly explored the cognitive processes underlying eating disorders (EDs), including anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), other specified feeding or eating disorders (OSFEDs), and individuals with higher weight (HW). This critical narrative review focuses on neurocognitive findings derived from mainly experimental tasks to provide a detailed understanding of cognitive functioning across these groups. Where experimental data are lacking, we draw on self-report measures and neuroimaging findings to offer supplementary insights.

: Altered eating behaviors (AEBs) are not only associated with eating disorders but also play a role in obesity. This study assessed AEBs in individuals with obesity and their association with general and eating psychopathology, using the "Eating Behaviors Assessment for Obesity" (EBA-O). The hypothesis posited that a higher frequency of pathological eating behaviors would correlate with more severe psychopathology.
