Anorexia Death Rates

Posted Feb 11 2009 3:28pm

My colleague, Ken Pope, Ph.D. recently sent me a new article that should serve as another wake-up call about the dangers of anorexia nervosa.

The new issue of the American Psychiatric Association's *Psychiatric News* (Volume 44, Number 3) includes an article: "Researchers 'Astonished' by Anorexia Death Rates" by Joan Arehart-Treichel.

Here are some excerpts:
 
Anorexia nervosa is a very dangerous illness, not just over the short term but over the long term as well. Patients with this disorder need continuing, diligent follow-up care.

Anorexia nervosa...is a dangerous illness with a high rate of premature death.

But exactly how dangerous has become clearer--the result of a nationwide longitudinal study conducted by Swedish scientists.

The study team reported two major findings. The first was that compared with the general population, anorexia patients were at a heightened risk of death not only after hospitalization but many years later.

The second was that their long-term risk of death came not just from anorexia but from a number of other causes as well.

The scientists were "astonished" by these findings, they wrote in their report published in the January British Journal of Psychiatry.

Thanks to the unique personal identification numbers assigned to all Swedish residents, and to the national cause-of-death records and national hospital-discharge records that Sweden maintains, these
researchers were able to assess death from natural and unnatural causes in a nation-wide cohort of Swedish women with anorexia nervosa. The researchers studied the records of some 6,000 patients covering a 30-ear period (1973 to 2003).
 
The most frequent causes of death were suicide (responsible for 32 percent of the deaths), anorexia (19 percent of the deaths), and cancer (11 percent of the deaths). The remaining 38 percent of deaths were caused by other illnesses or by homicide. The average age at death for the 265 anorexia patients who died was 34.

The researchers also compared findings for their anorexia patients during the 30-year follow-up period with those of the general Swedish population.

For example, compared with the general population during this time, anorexia subjects were 19 times more likely to have died from psychoactive substance use, primarily alcohol use, 14 times more likely
to have died from suicide; 12 times more likely to have died from respiratory diseases, 11 times more likely to have died from urogenital diseases, five times more likely to have died from gastrointestinal
diseases, and two times more likely to have died from either cardiovascular disease or from cancer.
 
Altogether, anorexia patients were six times more likely to have died during the 30-year follow-up period than was the general population.

"These results underline the need for careful follow-up of anorexia nervosa patients," Fotios Papadopoulos, M.D., Ph.D., a general psychiatry resident at Sweden's Uppsala University Hospital and the lead investigator, told Psychiatric News. 
 
Moreover, other researchers have found that a number of patients with anorexia do not have alcohol problems during the first part of their illness, yet develop them later. Thus, anorexia patients should be carefully monitored for signs that they may be developing alcohol dependence.

For those of us in the eating disorder field, while we might not be astonished, since we have long been aware of the dangers of anorexia nervosa, we are nevertheless reminded of the importance of fighting this illness because it is a killer, of lives, but also of families, of relationships, of health, and often of hope.
