eating disorders

A study published in the journal JAMA Psychiatry, which analysed the prevalence of anorexia and bulimia in 204 countries from 1990 to 2023 by age and sex, has found that the number of cases has risen by 71 per cent. In 2023, an estimated 18.1 million people worldwide were suffering from one of these two eating disorders, of whom 41.2 per cent were young people aged between 10 and 24, and 70 per cent were women. This figure is estimated to rise to 21.8 million by 2050.

22% of children worldwide have signs of disordered eating behaviours, a figure that rises to 30% for girls alone, according to an analysis published in JAMA Pediatrics led by researchers from the University of Castilla-La Mancha. The research brings together 32 previous studies that used the same diagnostic tool (the SCOFF questionnaire). It includes in total more than 60,000 children aged 6 to 18 in 16 countries. The article also states that the risk of disordered eating behaviour increases with age and Body Mass Index (BMI).  Disordered eating behaviours include behaviours such as ‘weight loss dieting, binge eating, self-induced vomiting, excessive exercise, and the use of laxatives or diuretics (although not to the level to warrant a clinical diagnosis of an eating disorder)’.
