What Is ARFID?
Avoidant/Restrictive Food Intake Disorder (ARFID) is an eating disorder characterized by a disturbed eating pattern that leads to inadequate nutritional and/or energy intake. Unlike anorexia nervosa or bulimia, ARFID does not involve distress about body weight or shape. Instead, the avoidance or restriction of food is driven by one or more of three distinct reasons: lack of interest in eating, avoidance based on sensory characteristics of food (texture, taste, smell), or fear of aversive consequences like choking or vomiting. It was added to the DSM-5 in 2013, recognizing that feeding issues extend beyond infancy and can occur at any age.
The Male-Predominant Trend in Clinical Samples
In stark contrast to the female predominance typically seen in other eating disorders, ARFID often shows a higher proportion of males, especially among younger patients in clinical settings. For example, studies of youth hospitalized for eating disorders have found that a significantly greater percentage of ARFID patients were male compared to those with anorexia nervosa. A retrospective chart review of patients in a pediatric inpatient eating disorder program found that up to one-third of the ARFID cases were boys. This clinical observation is critical because it highlights that ARFID can manifest in a male-majority demographic, making it essential for healthcare providers to screen for it without gender bias. Reasons for this clinical trend are still being explored, but they could be related to different symptom presentations or comorbidities that are more common in males.
Varying Results from Population-Based Studies
While clinical data points towards a male prevalence, studies in the general population present a more mixed picture, which underscores the difficulty in accurately assessing true prevalence. Some community-based research has found a more even distribution between sexes, while others have reported a slight female predominance, albeit with a very small effect size. For instance, one Australian study of adolescents found a slightly higher likelihood for girls to meet criteria for possible ARFID, contrary to some clinical findings. However, these population-based studies often rely on self-report screeners, which may be influenced by reporting biases or fail to capture the full severity of the disorder that leads to clinical intervention. The conflicting evidence suggests that the male-predominant trend may be most pronounced in severe or treatment-seeking populations, and that the prevalence in the broader community might be more balanced.
Different Ways ARFID Presents in Males and Females
Research indicates there may be age- and sex-specific differences in how ARFID manifests. One study found that, among younger patients, boys had a higher rate of refusing food based on sensory characteristics, while girls were more likely to report not eating enough. These variations in presentation suggest that ARFID may be triggered or maintained by different underlying factors depending on gender. The common association between ARFID and autism spectrum disorder (ASD) is another important factor, as ASD is also diagnosed more frequently in males. The sensory sensitivities and food-related rigidity common in both ASD and ARFID may help explain why a higher proportion of males end up with an ARFID diagnosis in some settings.
The Role of Under-diagnosis and Stigma
A major factor impacting prevalence statistics for ARFID, particularly in males, is the under-recognition and stigma surrounding male eating disorders. Societal misconceptions often frame eating disorders as a 'female' issue focused on weight and body image. Since ARFID is not linked to weight and shape concerns, it might not fit the public's perception of what an eating disorder looks like, leading to under-diagnosis in both sexes. However, this effect is amplified for males, who may face additional shame and stigma when seeking treatment for any eating disorder. This can result in delayed intervention and potentially more severe medical complications by the time they present for care.
Comparison of Male and Female ARFID Trends
| Characteristic | Males (Often) | Females (Often) |
|---|---|---|
| Prevalence in Clinical Samples | Higher proportion, especially in youth | Lower proportion compared to males with ARFID |
| Prevalence in Community Samples | May be closer to equal or slightly lower than females | May be closer to equal or slightly higher than males |
| Common Presentation in Youth | Higher rate of sensory-based food refusal | More likely to report not eating enough |
| Associated Comorbidities | High rates of co-occurring Autism Spectrum Disorder (ASD) | High rates of co-occurring anxiety disorders |
| Likelihood of Diagnosis | Higher risk of delayed diagnosis due to stigma | Less likely to experience same level of stigma as males |
| Medical Stability | May require more nutrition during hospital discharge | May present differently medically |
Conclusion
In conclusion, the question, "Is ARFID more common in males?" does not have a simple answer but points to a complex interplay of clinical presentation, study methodology, and social factors. While clinical data from treatment centers, particularly for younger age groups, consistently shows a higher proportion of males with ARFID compared to other eating disorders, population-based studies can yield different results. The different ways ARFID manifests, along with the impact of stigma and co-occurring conditions like ASD, may contribute to these variations. More comprehensive, population-level research is needed to fully understand the gender dynamics of ARFID. Crucially, recognizing that ARFID affects individuals of all genders is essential for timely and effective intervention, breaking down harmful stereotypes surrounding eating disorders.
