Clinical research has found that somewhere between 20 and 37 percent of diagnosed anorexia nervosa sufferers are Autistic.[24] Since Autism is underdiagnosed in the populations who are most likely to be diagnosed with eating disorders (women, trans people, and gay men), the actual rate of co-occurrence might be much higher. In conventional eating disorder treatment, Autistic patients have worse outcomes: they require longer hospital stays, are less likely to reduce their eating disordered behaviors, and experience more depression and social isolation in recovery groups.[25] However, eating disorder clinics and inpatient programs have started taking steps to accommodate their Autistic patients, with some promising results.
