According to a web page I read, a 2001 study found that although sex abuse has a positive correlation with idiopathic chronic fatigue, it has a negative correlation with CFS. The article cited Taylor RR, et al. Sexual abuse, physical abuse, chronic fatigue, and chronic fatigue syndrome: a community-based study. J Nerv Ment Dis. Oct 2001;189(10):709-15. BTW, the reason I am posting this is in case people want to counter the CDC information about this.
