It highlights the continual quest to improve diagnostic criteria and to make them more scientifically valid.
Here was the conclusion/summary"
These findings support the existence of three general classes of disordered eating behavior. These classes broadly resemble current classifications of anorexia nervosa, bulimia nervosa, and binge-eating disorder. Three additional atypical classes were also identified that may to some extent represent individuals at risk for the subsequent development of clinical eating disorders. The data also support the continued evaluation of diagnostic criteria such as amenorrhea and body image distortion for anorexia nervosa and a sense of loss of control during binging for both bulimia nervosa and binge-eating disorder. As only a small proportion of women with eating disorders ever seek treatment (12, 13), clinical samples only allow us to investigate a very select portion of the population of afflicted individuals. Community studies such as this are therefore preferred when addressing etiological factors or typology, and they allow us to view the disorders as they occur naturally in the population."
