Thank you for the honour of presenting to you on behalf of the Canadian Academy of Child and Adolescent Psychiatry, and on behalf of clinicians who treat eating disorders in youth.
As you know, eating disorders are devastating illnesses. Research suggests that it takes between two and seven years to recover from an eating disorder, and that only 50% fully recover. Eating disorders have the highest mortality rate of any psychiatric illness due to a combination of medical complications and suicide. For a variety of reasons, eating disorders and risk factors for developing eating disorders are on the rise.
I will begin with the social context.
Rates of body dissatisfaction in women are greater than 87%. Seventy percent of women are currently dieting to lose weight. In a survey of North American women, when offered any three wishes, the majority chose weight loss as their first wish. Ten million women in the U.S. suffer from an eating disorder, more than have breast cancer. I wish I had the equivalent numbers for Canada. We need a national registry for eating disorders. Canada does not know the number of eating disorder sufferers, the average wait times for treatment, or the percentage of patients who get treatment.
Here are more statistics. Forty to fifty per cent of girls aged 11 to 15 years say they need to lose weight, and 61% of Canadian grade 7 and 8 students were trying to lose weight. Researchers in Edmonton studied 700 children in grades 5 to 7. They found that more than 15% were purging or over-exercising, 16% were binge eating, and 19% were restricting to one meal per day or less.
Why is this significant? In a study of 14- to 15-year-old adolescent girls who engaged in strict dieting practices, they were 18 times more likely to develop an eating disorder within six months compared to non-dieters, and had almost a 20% chance of developing an eating disorder within one year.
Not only are eating disorders on the rise, but pediatric mental illness in general is on the rise in Canada and North America. Here are some more statistics. In any given year, one in five people in Canada experiences a mental health illness. Up to 70% of young adults living with mental health problems report that the symptoms started in childhood.
Severe, disabling mental illness has dramatically increased in the United States. In 2011, Marcia Angell reported that mental disorders in children increased by a startling 35 times between 1987 and 2007.
In 1998, Dr. Martin Seligman, then president of the American Psychological Association, presented the results of his research. He reported:
...there is now between ten and 20 times as much [depression] as there was 50 years ago. And...it has become a young person’s problem. ...thirty years ago...the average age of which the first onset of depression occurred was 29.5. Now the average age is between 14 and 15.
These statistics are valuable because, as a child and adolescent psychiatrist, it is important for me to put eating disorders into context, given that eating disorders are highly associated with other mental illnesses, especially with depression and anxiety.
Happy youngsters don’t develop eating disorders. An eating disorder develops when a young person feels not good enough, or literally and figuratively, as though they don’t deserve to take up a normal amount of space in this world. Eating disorders arise when a young person feels scared, sad, worried, guilty, angry, stressed, or unworthy to such an extent that starving herself seems like a better alternative, a way to cope with those intolerable feelings and to help her feel good enough. An eating disorder is thus a form of self-treatment akin to drug and alcohol addictions, only in this case, the youth gets addicted to bingeing and purging or to seeing the numbers on the scale go down.
Unfortunately, one side effect of lack of nutrition is increased obsessiveness, so what might start out as a diet or weight loss plan can spiral out of control into an illness similar to obsessive-compulsive disorder, in which the obsessive thought is “I’m eating too much, I’m gaining too much weight”, and the patient then feels compelled to decrease the intensity of these obsessive worries through symptoms such as restricting, purging, and exercising.
Associated extreme hunger can then lead to bingeing, although in children, they often just continue to restrict, and lose more and more weight.
Thus, as you can imagine, eating disorders are highly associated with other mental illnesses, including anxiety, depression, obsessive-compulsive disorder, and substance abuse. As those illnesses increase in number so do eating disorders. But other factors are also associated with the rise in eating disorders, including an increase in anxiety about the food we eat and the epidemic of obesity; an increasing emphasis on appearances and celebrity culture; and the huge diet and weight loss industry, all of which lead more and more young females to feel self-conscious and not good enough about their looks.
As mental illnesses and eating disorders have increased the resources and small number of clinicians available to treat these disorders have not been able to keep up with the demand. The number of family doctors trained in the treatment of eating disorders is almost nil. Community mental health agencies lack time or funding for training in eating disorders, and are overwhelmed by mental health referrals in general. There is a terrible shortage of psychiatrists across the country, even fewer child and adolescent psychiatrists, and only a very small handful of us who have specialized training in the treatment of pediatric eating disorders.
So what can we do to improve the situation? Let’s examine the various levels of intervention, starting with prevention.
One challenge is that efforts to prevent obesity have actually increased the number of eating disorders. I am frustrated by hearing one story after another of young girls whose eating disorder was triggered by a health class, school project, teacher, coach, or family doctor. We need more research into the causes and risk factors and how to prevent eating disorders, including how to prevent obesity without causing a concomitant increase in eating disorders.
We need to find a message of balance, moderation, size acceptance, and healthy body image that applies to all. We still don’t know enough about how to prevent eating disorders. We know that teaching eating disorders in school not only does not help, it actually increases the number of eating disorders. Yet, have we been effective in changing this in the schools? No. It is part of the curriculum and thus difficult to change.
We also need to do a better job of teaching family doctors and medical students, not just about eating disorders but also about the dangers of dieting, that low weight is as unhealthy as overweight, and how to treat obesity without causing eating disorders.
We need to train family doctors to screen for eating disorders and to have the language to talk to girls about nutrition, body image, and eating disorder thoughts, urges, and symptoms.
We need to send more trained mental health nurses into the high schools to help young people who are struggling with depression, anxiety, and eating disorders.
We need more trained community health counsellors who can counsel students who suffer from depression, anxiety, self-injurious behaviour, eating disorders, and addictions.
At the secondary level of care, we find girls with severe anorexia nervosa admitted to smaller community hospitals where the doctors and nurses do not understand eating disorders and are frustrated by the adolescent’s stubborn refusal to take nutrition. They resort to behavioural approaches, which often involve sending parents away while the young person stays alone in bed all day until she earns her privileges. This doesn't make sense when you understand that the patient is being controlled by the illness, rather than the other way around.
I also hear horror stories of young girls being sent home from the emergency department at dangerously low weights because their blood work is normal. If only the doctors understood that these girls meet the definition of medically unstable by their low weight alone, despite their body’s attempts to compensate for the starvation.
I hear of family doctors who, when faced with teenage girls with obsessive exercising and low heart rates who have lost their menstrual periods, reassure concerned mothers that this is just an effect of being a top athlete.
I often hear my colleagues in child psychiatry say they don’t treat eating disorders, or they don’t get eating disorders. They can't understand how an underweight teenager can refuse food because she's “too fat”. If only they could be helped to understand that this is similar to a person with obsessive-compulsive disorder, who can't stop cleaning their house or washing their hands. It has nothing to do with how clean the house is or how dirty their hands are but instead with the intensity of the obsessions and compulsions.
Many clinicians find it too frustrating to treat an illness in which a young person is extremely medically and psychologically compromised, is angry and depressed, does not want help because she's terrified it will cause weight gain, often resists treatment, and usually takes a very long time and a lot of specialized care to treat. The clinician has to be comfortable working with not just these patients but also their families. Given that most communities have a terrible shortage of child psychiatrists, few of these psychiatrists have enough time to dedicate to these patients or to their distraught, exhausted parents and families.
