A new international study reveals that teenagers from lower-income and lower-education households face a higher risk of eating disorders, challenging the long-standing stereotype that these conditions exclusively affect wealthy families and leaving disadvantaged adolescents vulnerable to missed diagnoses.
For decades, medical assumptions surrounding eating disorders have leaned heavily on a single stereotype: that conditions like anorexia, bulimia, and binge eating disorders are issues predominantly found in wealthy, well-educated households. A comprehensive new review published in the turns that conventional wisdom upside down, showing that economic and social disadvantage actually correlates with a greater risk of disordered eating symptoms among teenagers.
What the Global Data Review Reveals About Socioeconomic Disparity

The study was co-led by researchers at University College London (UCL) in collaboration with researchers at Copenhagen University Hospital. To arrive at their findings, the research team reviewed data spanning 51 studies that collectively involved 26,174 adolescents across Western countries, including North America, Europe, and Australia. Alongside clinical diagnoses, the review tracked early warning signs of disordered eating, such as fasting, food restriction, poor body image, and a persistent pressure to become thinner.
Among the various socioeconomic factors analyzed, family income emerged as the most consistent and powerful predictor. Approximately two-thirds of the reviewed studies indicated that teenagers from lower-income families experienced higher rates of eating disorder symptoms, with zero studies finding the opposite trend. Parental education played a similarly measurable role. According to the findings, teenagers whose parents did not attend university faced roughly a 25% higher likelihood of reporting eating disorder symptoms compared to peers whose parents went to university. At the same time, other indicators—such as neighbourhood deprivation, parental occupations, financial hardships, or the receipt of government benefits—yielded more mixed and inconsistent patterns.
The Dangerous Toll of Outdated Medical Stereotypes

This persistent cultural assumption that eating disorders are a problem of affluence carries real-world consequences for healthcare access. When clinicians, school counsellors, and healthcare professionals view eating disorders exclusively through the lens of affluence, young people from lower-income and lower-education backgrounds frequently get overlooked. Consequently, these adolescents are under-screened and often fail to receive timely diagnoses or necessary medical interventions.
Dr Nora Trompeter, senior author of the study from the UCL Great Ormond Street Institute of Child Health, emphasized that failing to look past old stereotypes leaves the most vulnerable young people undiagnosed and untreated. The research received financial support through grants provided by UK Research and Innovation and the Novo Nordisk Foundation.
Broader Scope and Institutional Recommendations

While the review covers data from multiple Western regions, the authors noted specific study limitations. The vast majority of the analyzed research focused on White adolescents from Western countries. Furthermore, individual studies measured family socioeconomic status in varied ways, which introduces complexity when drawing definitive conclusions regarding specific metrics like parental education.
In response to these findings, the research team is urging frontline professionals—including school counsellors, healthcare providers, and clinical practitioners—to expand their criteria for who might be at risk. Challenging these prevailing assumptions, the researchers argue, is a necessary step toward reducing missed diagnoses and ensuring timely support reaches teenagers across the entire socioeconomic spectrum.
