“…6 In this sample, psychotic experiences at age 13 years were associated with greater disordered eating behaviours, including fasting and binge eating, at age 18 years. 7 Clinical studies also found that individuals with non-affective psychoses had greater disordered eating, including binge eating, 4 and that individuals with eating disorders, and in particular those who binge eat, 22 display greater comorbidity with psychotic illnesses 1 or psychotic symptoms. 22 Shared genetic liability between schizophrenia, bipolar disorder and major depressive disorder 8 could explain our findings.…”

BackgroundRecent studies suggest psychotic and eating disorders can be comorbid and could have shared genetic liability. However, this comorbidity has been overlooked in the epidemiological literature. AimsTo test whether polygenic risk scores (PRS) for schizophrenia are associated with disordered eating behaviours and body mass index (BMI) in the general population. MethodUsing data from the Avon Longitudinal Study of Parents and Children and random-effects logistic and linear regression models, we investigated the association between PRS for schizophrenia and self-reported disordered eating behaviours (binge eating, purging, fasting and excessive exercise) and BMI at 14, 16 and 18 years. ResultsOf the 6920 children with available genetic data, 4473 (64.6%) and 5069 (73.3%) had at least one disordered eating and one BMI outcome measurement, respectively. An s.d. increase in PRS was associated with greater odds of having binge eating behaviours (odds ratio, 1.36; 95% CI 1.16-1.60) and lower BMI (coefficient, −0.03; 95% CI, −0.06 to −0.01). ConclusionsOur findings suggest the presence of shared genetic risk between schizophrenia and binge eating behaviours. Intermediate phenotypes such as impaired social cognition and irritability, previously shown to be positively correlated in this sample with schizophrenia PRS, could represent risk factors for both phenotypes. Shared genetic liability between binge eating and schizophrenia could also explain higher rates of metabolic syndrome in individuals with schizophrenia, as binge eating could be a mediator of this association in drug-naïve individuals. The finding of an association between greater PRS and lower BMI, although consistent with existing epidemiological and genetic literature, requires further investigation.

“…Also, we found a significant relationship (28.6%) between eating disorder symptoms and psychoticism symptoms (P<0.05). In a study on personality characteristics and body weight, a significant relationship between psychotic personality characteristics and patients' weight was reported (Aragona, Petta, & Balbi, 2015).

Objective: Obesity and overweight are global problems. They increase patient’s morbidity and mortality and may cause severe medical conditions affecting physical, mental, and or social health. Bariatric surgery is a durable solution for treating morbid obesity. This study aimed to determine the associations between psychiatric problems and eating disorder symptoms in candidates for bariatric surgery. Methods: In this cross-sectional study, 140 participants were selected from the patients who had already been referred to the obesity clinic in Firoozgar Hospital in Tehran, Iran, for bariatric surgery from April to June 2017. To collect study data, we used the eating disorder questionnaire for assessing eating disorders and the symptom checklist questionnaire for evaluating psychiatric problems. Results: The results of the Chi-squared test showed a significant association (P<0.05) between eating disorder symptoms and psychiatric problems (phobia, anxiety, depression, obsessive-compulsive, psychoticism, hostility, paranoid ideation, and somatization). However, there was no significant correlation (P>0.05) between eating disorder symptoms and interpersonal sensitivity. Conclusion: This study showed that eating disorders were significantly correlated with psychiatric problems.

Co-occurring psychotic and eating disorders in England: findings from the 2014 Adult Psychiatric Morbidity Survey

Background Psychotic disorders and eating disorders are complex mental illnesses associated with increased mortality and functional impairment. This study aimed to investigate the co-occurrence and relationships between eating disorders and psychotic disorders and assess the mediation effect of mood instability. Methods This study used data from the Adult Psychiatric Morbidity Survey (APMS) 2014, a general population-based survey in England. Participants (total N = 7546, female N = 4488, male N = 3058, mean age = 52.3 years) were categorised based on psychotic disorder status into the groups of probable psychosis, diagnosed psychosis, and healthy controls without psychosis. The dependent variable of this study was the presence or absence of an eating disorder, with mood instability as the mediator. Logistic regression and mediation analyses were conducted to assess the relationships between these variables. Results Both probable and diagnosed psychoses were significantly related to the presence of an eating disorder, and mood instability was found to be a mediating variable with moderate effect. Conclusion The present study demonstrates a significant relationship between eating disorders and psychotic disorders in the English general population, indicating higher levels of co-occurrence between these two groups of disorders than when compared with healthy controls. The findings also suggest the relationship between eating and psychotic disorders is mediated, to an extent, by the presence of mood instability traits. Future research could extend the present study’s findings through assessing whether specific eating disorders are more significantly related to psychotic disorders than others.
