One in 10 adolescent girls are estimated to have used diet pills, laxatives or diuretics in their lifetime, according to a new study.
The study, published Wednesday in the journal JAMA Pediatrics, analyzed over 90 studies with 600,000 participants around the world. The study's authors concluded that the findings suggest "interventions are required to reduce use of weight-loss products" in the population of teen girls.
"[The] use of nonprescribed weight-loss products in adolescents is a public health concern that is associated with negative physical and psychological consequences," the authors wrote.
Over-the-counter diet pills are often composed of supplements that have not been proven to help people lose weight in the long-term. Similarly, laxatives and diuretics do not help people lose weight in the long-term.
Prior research has shown that the use of diet pills is highly correlated with developing an eating disorder. Among U.S. young women, using diet pills and laxatives is associated with a higher risk of an eating disorder within 1 to 3 years compared to non-users, according to a study by the American Public Health Association.
Nearly 30 million Americans will have an eating disorder in their lifetime, according to the National Association of Anorexia Nervosa and Associated Disorders.
Among adolescent females, eating disorders are the third most common chronic illness, according to the National Institute of Mental Health, which defines eating disorders as "serious and often fatal illnesses that are associated with severe disturbances in people's eating behaviors and related thoughts and emotions."

Eating disorders can affect people of any age. New research has also shown that children younger than adolescents may engage in disordered eating behaviors, which can lead to eating disorders, according to the NIMH.
One study, published in 2022, showed that 5% of children -- both boys and girls -- engaged in binge eating, one of many types of disordered eating behaviors.
A more recent study, published last February, estimated 22% of children and adolescents showed disordered eating, defined in that study "as any behaviors 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."
Parents may often be the first to notice disordered eating behaviors at home. Here are some symptoms to watch for, according to the NIMH.
If parents notice their child may be developing or already have an unhealthy relationship with food or weight, it is important to seek professional medical help, according to the NIMH. As a starting point, parents can begin by initiating a conversation with their child's pediatrician.
