The number of people living with anorexia nervosa or bulimia nervosa worldwide increased 71% between 1990 and 2023 and is expected to continue rising, according to a study published in JAMA Psychiatry . Researchers estimated that 18.1 million people globally were living with one of the two eating disorders in 2023, with nearly 70% of cases occurring among females. Young people were particularly affected, with 41% of cases occurring among individuals ages 10 to 24. The study, “Global Burden of Anorexia Nervosa and Bulimia Nervosa, 1990 to 2023, with Forecasts to 2050: A Global Burden of Disease Study 2023 Analysis,” also found that disability‐adjusted life‐years associated with anorexia nervosa and bulimia nervosa increased 21% over the study period, underscoring the growing public health burden of these conditions. Bulimia nervosa was substantially more common than anorexia nervosa, affecting an estimated 14.2 million people globally compared with 3.9 million. Researchers project the number of people living with the disorders will increase another 20% by 2050.
