A new Danish study shatters the myth that eating disorders primarily affect privileged teenage girls. Young people from less educated families actually have higher rates of symptoms but are far less likely to get a diagnosis.
For years, the image was clear: eating disorders were a middle-class problem. Anxious teenage girls from well-off homes, pushed by high expectations and glossy Instagram feeds. The data told that story because those were the kids showing up in hospital records and specialist clinics.
Turns out, we were looking in the wrong places.
A new register study from the University of Copenhagen examined roughly one million Danish children and young people in national registries, plus survey data from 44,000 youth about symptoms of anorexia, bulimia, and binge eating disorder. The findings flip the script entirely.
The Diagnosis Gap
Young people whose parents have long higher education are 35 percent more likely to receive an official eating disorder diagnosis than those whose parents hold shorter tertiary degrees. Kids from families where parents only finished primary school have 30 percent lower risk of getting diagnosed.
But when researchers looked at self-reported symptoms rather than formal diagnoses, the pattern reversed completely. Youth from the least educated families have more than double the risk of experiencing eating disorder symptoms compared to the reference group.
That is not a small discrepancy. It suggests a massive blind spot in Danish healthcare. Thousands of young people are struggling silently while their more privileged peers get identified and treated.
Why the Gap Exists
The researchers point to several likely causes. Wealthier families have better access to health information and know how to navigate the system. They trust doctors more and are more comfortable seeking help for mental health issues. And crucially, general practitioners may be more alert to eating disorder symptoms when they see a patient from a well-educated background.
This is not about deliberate bias necessarily. It is about pattern recognition and resource access. If you expect eating disorders to show up in certain demographics, you spot them there. If a family lacks the vocabulary or confidence to push for psychiatric referral, the symptoms get missed.
Denmark already struggles with psychologist shortages and long wait times for mental health treatment. Adding social inequality to that mix makes a bad situation worse.
The Numbers Keep Rising
This study lands amid alarming national trends. Data from the National Institute of Public Health at the University of Southern Denmark shows that the share of women aged 16 and over with risk behavior for eating disorders more than doubled between 2000 and 2023, jumping from 10 percent to 21 percent.
Regional data cited by KL shows diagnoses among youth have doubled in the past 15 years. A peak occurred during the COVID pandemic, but the upward trend was already established before lockdowns began.
Estimates of total affected Danes vary wildly depending on methodology. Municipal and regional treatment data suggest around 13,500 people currently have or recently had an eating disorder. Psychiatric organizations estimate 75,000. Patient advocacy groups now claim closer to 98,000 Danes live with the condition in mild, moderate, or severe form.
The spread between those figures tells its own story. Treatment data only captures people who made it into the system. Survey and extrapolation methods attempt to count everyone, including those the system never sees.
Biology, Not Vanity
Recent Danish research has also dismantled another stubborn myth: that eating disorders are about vanity or lifestyle choices. Studies from the University of Copenhagen and the University of Southern Denmark show that severe imbalances in gut bacteria directly contribute to anorexia development and persistence.
Other research documents that neurotransmitters in the brain can malfunction in people with eating disorders. The brain literally tells them they are overweight when they are dangerously thin. Register studies find that getting an eating disorder diagnosis quadruples the risk of subsequent psychiatric illness. Around 40 percent of people with eating disorders develop another mental health condition within 10 to 12 years.
This is not a choice. It is a serious psychiatric condition with biological drivers and high comorbidity. Yet the old narrative persists, particularly in public perception and sometimes even among healthcare providers.
Policy Response
The Danish Health Authority has allocated 49.3 million kroner for strengthened efforts targeting eating disorders and self-harm between 2025 and 2028. Regions, municipalities, private providers, and civil society organizations can apply for funding. The deadline was April 25, 2025, with projects required to launch by August 1, 2025.
A national clinical quality database for eating disorders is also being established, expected to begin operations in autumn 2025. The database will track diagnosis, treatment, and outcomes across the country, potentially revealing geographic and social disparities in care.
These are steps forward. But they come after years of mounting evidence that the system was failing large segments of the population. The University of Copenhagen study makes clear that waiting for young people from disadvantaged backgrounds to show up in clinics is not a strategy. Active screening, outreach, and education in schools and primary care are essential if Denmark wants to close the diagnosis gap.
