Teens from poorer households face higher eating disorder risk, major review finds

Eating disorders have long carried a stubborn cultural stereotype: the image of the affluent, high-achieving teenager, typically white and typically well-off, whose perfectionism curdles into anorexia or bulimia. A new systematic review co-led by researchers at University College London dismantles that picture. Drawing on data from 51 studies covering 26,174 adolescents across North America, Europe and Australia, the review found that teenagers from households with lower income and lower parental education are actually more likely to show signs of disordered eating, not less. The work, published in the International Journal of Eating Disorders and conducted in collaboration with researchers at Copenhagen University Hospital, is one of the most comprehensive attempts to map the relationship between family socioeconomic status and eating disorder symptoms in adolescence, and its conclusions carry uncomfortable implications for how clinicians, schools and parents decide who is worth screening.

The scale of the evidence base is what gives the finding its force. The researchers pooled observational studies from Western countries, examining not only diagnosed conditions such as anorexia nervosa, bulimia nervosa and binge eating disorder, but also the early warning symptoms that precede formal diagnosis. These included restricting food intake, fasting, poor body image, and feeling a persistent pressure to become thinner. Capturing this broader spectrum matters because eating disorders often begin quietly, with behaviours and attitudes that never reach a clinic until the illness is entrenched. By including subclinical symptoms, the review could detect patterns that diagnosis-based datasets alone would miss, particularly in populations where access to specialist care is already limited.

Among the various measures of socioeconomic background, family income emerged as the strongest and most consistent correlate. Roughly two-thirds of the reviewed studies found that teenagers from lower-income families were more likely to exhibit eating disorder symptoms, and, strikingly, no studies found the opposite association. In epidemiology, where individual studies frequently disagree and effect directions flip between cohorts, such one-sided consistency is unusual. It suggests that the relationship between economic disadvantage and disordered eating is not a statistical artefact of one dataset but a pattern replicated across dozens of independent samples, methods and national contexts.

Parental education told a similar story. Teenagers whose parents had more education were less likely to show symptoms of an eating disorder. In one illustrative comparison, adolescents whose parents had not attended university were around 25 per cent more likely to report eating disorder symptoms than those whose parents had gone to university. The authors caution that education was measured in different ways across the included studies, but that the measures broadly map onto whether parents held a university-level qualification. Even with that imprecision, the direction of the effect aligns with the income findings: advantage, in this domain, appears protective rather than risk-elevating.

Not every socioeconomic indicator behaved so cleanly. Measures such as neighbourhood deprivation, parental occupation, financial difficulties within the household, and receipt of government benefits produced far more mixed and inconsistent results across the literature. That heterogeneity is itself informative. Income and education are relatively stable, well-recorded characteristics of a household, whereas benefits receipt or neighbourhood-level deprivation may capture different things in different countries and welfare systems. The inconsistency may also reflect how thinly these variables have been studied compared with income and education. For researchers, the message is that the choice of socioeconomic measure is not neutral, and future work should be explicit about which dimension of disadvantage it is testing.

Senior author Dr Nora Trompeter, of UCL Great Ormond Street Institute of Child Health, said the stereotype of eating disorders as a problem of affluence is not the full picture. She noted that the review found teenagers from lower-income, lower-education households are actually more likely to show signs of disordered eating, and argued that prevention and treatment efforts therefore need to reach families facing financial and social disadvantage who may currently be overlooked. In a further statement, she was blunt about the stakes: eating disorders do not discriminate by income or education, and if anything the evidence points the other way, so treating them as a privileged condition risks leaving the adolescents most in need of support undiagnosed and untreated.

The clinical consequences of that stereotype are easy to trace. If parents, teachers and general practitioners assume that eating disorders concentrate among wealthy families, then a teenager from a low-income household who is skipping meals, fasting or expressing intense body dissatisfaction may not trigger the same alarm. Screening tools may be applied less readily, referrals may be delayed, and the young person themselves may not recognise their experience as an illness worth reporting. The researchers are now calling on clinicians, healthcare professionals and school counsellors to broaden their assumptions about who is at risk, in order to improve early identification. Challenging outdated stereotypes, they argue, could directly reduce missed diagnoses and get timely treatment to the young people who need it most.

The review also raises broader questions about why disadvantage might amplify eating disorder risk, and the authors are careful not to overclaim mechanisms from observational data. Plausible pathways discussed in the wider literature include chronic stress associated with financial hardship, food insecurity that can disrupt regular eating patterns and later contribute to binge-type behaviours, limited access to mental health services, and social pressures around body image that cut across class lines. None of these mechanisms is confirmed by the review itself, which is designed to establish the association rather than explain it. But the consistency of the income and education findings gives researchers a clear target for the next generation of studies, which should follow adolescents over time to test whether disadvantage precedes and contributes to disordered eating rather than merely co-occurring with it.

The study has limitations that the authors acknowledge openly. Most of the included research involved mainly white adolescents from Western countries, meaning the findings may not generalise to other ethnic groups or to low- and middle-income countries, where the relationship between socioeconomic status and eating behaviour could differ substantially. The reviewed studies also used different ways of measuring family socioeconomic status, which makes it difficult to draw firm, quantified conclusions about effect sizes across the whole body of evidence. The 25 per cent figure associated with parental education should be read in that light, as an illustration of the direction of the association rather than a precise universal estimate. These caveats temper but do not undermine the central result, which rests on the sheer consistency of the income findings across dozens of studies.

What the review ultimately delivers is a course correction. Eating disorders are among the most lethal psychiatric conditions, and early treatment markedly improves outcomes, which makes systematic under-recognition in any population a serious public health failure. If the prevailing stereotype has steered clinical attention toward affluent, well-educated families while the epidemiological evidence points the other way, then thousands of adolescents from disadvantaged backgrounds may be slipping through unexamined. The research team, whose work was supported by grants from UK Research and Innovation and the Novo Nordisk Foundation, hopes the findings will prompt a practical shift: wider screening assumptions in primary care and schools, greater awareness among families facing financial and social disadvantage, and research funding directed at understanding and interrupting the pathways that link hardship to disordered eating. For a field that has spent decades fighting one stereotype about who gets eating disorders, the data now demand that it fight another.
