Psychotic-like experiences and disordered eating in the English general population

There are no studies on psychotic-like experiences (PLEs) and disordered eating in the general population. We aimed to assess this association in the English adult population. Data from the 2007 Adult Psychiatric Morbidity Survey (APMS) were analyzed. This was a nationally representative survey comprising 7403 English adults aged ≥16 years. The Psychosis Screening Questionnaire was used to identify the past 12-month occurrence of five forms of psychotic symptoms. Questions from the five-item SCOFF screening instrument were used to identify those with eating disorder (ED) symptoms and possible ED in the past year. The prevalence of any PLE was 5.1% (female) and 5.4% (male), while that of possible ED was 9.0% (female) and 3.5% (male). After adjustment for potential confounders, possible ED was associated with hypomania/mania in females (OR=3.23 95%CI=1.002-10.39), strange experiences [females (OR=1.85 95%CI=1.07-3.20) and males (OR=3.54 95%CI=1.65-7.57)], and any PLE in males (OR=3.44 95%CI=1.85-6.39). An interaction analysis revealed that the association was stronger among males for: auditory hallucinations and uncontrolled eating; and any PLE with uncontrolled eating, food dominance, and possible ED. Clinical practitioners should be aware that PLEs and disordered eating behavior often coexist. When one condition is detected, screening for the other may be advisable, especially among males.
