The Prevalence and Burden of Avoidant/Restrictive Food Intake Disorder (ARFID) Symptoms in the Adult General Population of the UK and USA.
Article in The International journal of eating disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAvoidant/Restrictive Food Intake Disorder (ARFID) is a feeding and eating disorder characterized by avoidant/restrictive eating behaviors that lead to medical and/or functional impairments. While ARFID is increasingly recognized within pediatric populations and specialist clinics, data on its prevalence and burden within the adult general population remain sparse. We sought to address this knowledge gap.
methodsWe conducted a population-based internet survey with predefined demographic quotas across the UK and USA. The survey included the Nine-Item ARFID Screen (NIAS), the Rome IV diagnostic questionnaire for disorders of gut-brain interaction (e.g., irritable bowel syndrome, functional dyspepsia), and questions regarding demographics, body mass index, somatic symptoms, anxiety and depression, quality of life, and healthcare utilization.
resultsAmong 4002 participants (mean age 47.1 years, 50% female), 26.0% screened positive for ARFID. Prevalence was significantly higher in females versus males (29.6% vs. 22.1%, OR 1.48, 95% CI 1.28-1.71) and varied by age: 18-39 years (31.6%), 40-64 years (25.0%), and ≥ 65 years (16.1%; p < 0.001). Participants with a positive ARFID screen demonstrated significantly higher rates of underweight status, disorders of gut-brain interaction, mood disturbances, somatic symptoms, reduced mental and physical quality of life, and increased healthcare utilization compared to unaffected individuals. Increasing severity of ARFID correlated with greater general health impairment (all p < 0.001).
conclusionA positive ARFID screen is common within the adult general population, affecting 1-in-4 people, and associated with a substantial health burden. Increased awareness of ARFID will facilitate clinical service provision and guide future research.
