Background: Avoidant/restrictive food intake disorder (ARFID), an eating disorder not associated with weight and shape concerns, results in nutrient or energy deficiencies related with further health consequences and a pronounced need for specialized treatment. These interventions need to be tailored to individual health behavior. However, research about health behavior and treatment utilization in ARFID is scarce, particularly in adults, as ARFID is more common in children despite occurring across the lifespan. One important aspect of health behavior is the individual's health regulatory focus (i.e., health prevention and health promotion). Additionally, symptoms of eating disorders have generally been associated with various health risk behaviors, such as smoking, drinking, or unhealthy physical (in)activity. Therefore, the present study aimed to investigate health behavior and psychological treatment utilization in adults with symptoms of ARFID.
Methods: A representative adult population sample (N = 2415) completed several self-report questionnaires assessing symptoms of eating disorders and health behavior. Differences between groups (symptoms of ARFID vs. no symptoms of ARFID) were tested with analysis of variance, Mann-Whitney-U-tests, and binary logistic regression.
Results: Individuals with symptoms of ARFID (n = 20) did not differ in their health regulatory focus, smoking status, physical activity or psychological treatment utilization from individuals without symptoms of ARFID (n = 2395). However, they reported higher alcohol misuse than individuals without symptoms of ARFID.
Conclusion: The findings suggest a relevance of further exploration of the relationship between alcohol misuse and ARFID, given the preliminary nature of these results. This exploration could inform treatment strategies for addressing potential comorbid substance misuse. Furthermore, the low psychological treatment utilization in adults with symptoms of ARFID suggest a need for more specialized psychological treatment services, public education about ARFID being an indication for psychological treatment, and further research about treatment barriers.

Avoidant/restrictive food intake disorder (ARFID), an eating disorder not associated with body image or weight concerns, results in nutrient or energy deficiencies related with further health consequences. It is most common in children, but can occur across the lifespan, although there is little research in adults. Therefore, the study investigated if adults with symptoms of ARFID differ from adults without symptoms of ARFID in health behaviors. A total of 2415 adults from a German national population sample completed questionnaires assessing symptoms of ARFID, health regulatory focus (health promotion focus with the aim of improving one’s health and health prevention focus aiming to avoid any deterioration in health), alcohol misuse, smoking behavior, physical activity and psychological treatment utilization. Adults with symptoms of ARFID did not differ from those without symptoms of ARFID in treatment utilization or any of the assessed health behaviors except reporting higher alcohol misuse. We, therefore, suggest to further explore potential alcohol misuse in individuals with ARFID. Furthermore, more research about treatment barriers in ARFID and more specialized psychological treatment services as well as public education about ARFID being an indication for psychological treatment, are needed to address the low psychological treatment utilization.
