Approximately 0.5% of the Australian population has bulimia nervosa in any given year, while the lifetime prevalence is estimated to be around 1.85%.
The average age of onset for bulimia is eighteen, with an overall prevalence of 0.3%. Broken down by gender, bulimia develops in 1.5% of women and 0.5% of men, making it five times more common to develop in women.
One in five Australian adults experience a mental illness every year. About 45 per cent of Australian adults will be affected by mental illness at some time in their life. Anxiety, mood disorders (such as depression) and substance use disorders are the most common mental illnesses experienced by Australian adults.
At the country level, the top three countries with the highest ASDR for eating disorders in 2021 were Switzerland (0.06, 95% UI: 0.04–0.07, per 100,000), Japan (0.04, 95% UI: 0.03–0.05, per 100,000), and the Netherlands (0.04, 95% UI: 0.03–0.05, per 100,000) (Supplementary Figure S1).
Common eating disorders include binge eating disorder, bulimia nervosa, and, less common but very serious, anorexia nervosa. Additional information about eating disorders can be found on the NIMH Health Topics page on Eating Disorders.
They are not a “diet gone wrong”' – in fact, anorexia nervosa has the highest mortality rate of any mental illness. They often cause major physical health problems and without the right support people with eating disorders often become isolated: cut off from education, work or a social life.
Prader-Willi (PRAH-dur VIL-e) syndrome is a rare genetic condition that leads to physical, mental and behavioral problems. A key feature of Prader-Willi syndrome is a sense of being hungry all the time. People with Prader-Willi syndrome want to eat all the time because they never feel full.
Anorexia nervosa is oftentimes cited as the most dangerous eating disorder due to its alarming mortality rate; anorexia has the highest mortality rate among mental health conditions. Each year, approximately 5.1 deaths per 1000 are due to anorexia.
However, the prevalence of any threshold or subthreshold eating disorder (19.8% White, 19.9% Hispanic American, 20.7% African American, and 21.5% Asian American) were compared and no significant differences were found (χ2[3,1177] = 0.23,p = . 97).
Epidemiological studies have shown that anorexia nervosa (AN) and bulimia nervosa (BN) are more common among females than males.
Dementia, including Alzheimer's disease is now Australia's leading cause of death. Ischaemic heart diseases are at their lowest rate in the available time series. There were 187,268 registered deaths in 2024, an increase of 4,137 since 2023.
The 5 C's of Mental Health provide a framework for well-being, often cited as Competence, Confidence, Connection, Character, and Caring, focusing on feeling capable, believing in oneself, nurturing relationships, living by values, and showing empathy. While some variations exist, like adding Compassion, Coping, or Community, the core idea is building resilience through personal growth and strong relationships, helping individuals manage challenges and thrive.
Prevalence Among Adolescents
Studies indicate that: Early Onset: The average age of onset for bulimia nervosa is between 18 and 19 years old, but it can start as early as 12. Teenage Girls: Among adolescents, bulimia is more prevalent in females. Approximately 1-2% of teenage girls are affected by bulimia.
Abstract. We contend that the eating disorders of anorexia nervosa and bulimia nervosa are more common among women than men because more women are dieting to control their weight.
Eva Schoen, PhD, assistant professor of psychiatry and clinical director of eating disorders services at University of Iowa Health Care, says binge eating disorder, or BED, is the most common eating disorder, even though it's not talked about as much as other eating disorders, such as anorexia or bulimia.
The most common eating disorders are anorexia, bulimia and binge-eating disorder. Most eating disorders involve focusing too much on weight, body shape and food. This can lead to dangerous eating behaviors. These behaviors can seriously affect the ability to get the nutrition your body needs.
Gender differences in food intake and selection first appear in adolescence. Men consume more calories than women, and the sexes have different eating styles, which indicate that women have been socialized to eat in a more feminine manner.
Among individuals with eating disorders, the two most prevalent personality disorders appear to be obsessive compulsive personality disorder (anorexia nervosa, restricting type) and borderline personality disorder (anorexia nervosa, binge-eating purging type; bulimia nervosa).
Less common eating disorders:
How common are eating disorders? The eating disorders anorexia nervosa and bulimia nervosa, respectively, affect 0.5 percent and 2-3 percent of women over their lifetime.
Individuals with eating disorders (EDs) had significantly elevated mortality rates. Anorexia nervosa had the highest standardized mortality ratios compared to other EDs.
You and your family doctor need to get at those feelings and help your child develop ways to cope with them. Most of the time, you'll find compulsive eating has nothing to do with hunger. It's a habit kids—and adults—develop to ease stress, depression, anxiety or even boredom.
Bulimia nervosa statistics
Around 1.5% of women will have bulimia nervosa in their lifetime. Around 0.5% of men will have bulimia nervosa in their lifetime.
The first formal description and diagnosis of anorexia as a medical condition occurred in England during the 1680's. Historical documents show that Dr. Richard Morton of London described his twenty-year-old patient in 1686 as “a skeleton clad with skin”.
