I'm pretty sure this report has been changed; I don't remember the acronym CDF being used before.
Anyone have the 'original'?
this was the aged 16:

"RESULTS: The prevalence of CFS was 1.86% (95% confidence interval [CI]: 1.47 to 2.24). After excluding children with high levels of depressive symptoms, the prevalence was 0.60% (95% CI: 0.37 to 0.84). Authorized school absences were much higher (mean difference: 35.6 [95% CI: 26.4 to 44.9] half-day sessions per academic year) and reported depressive symptoms were much more likely (odds ratio [OR]: 11.0 [95% CI: 5.92 to 20.4]) in children with CFS than in those without CFS. Female gender (OR: 1.95 [95% CI: 1.33 to 2.86]) and family adversity (OR: 1.20 [95% CI: 1.01 to 1.42] per unit family adversity index) were also associated with CFS.
CONCLUSIONS: CFS affected 1.9% of 16-year-olds in a UK birth cohort and was positively associated with higher family adversity. Gender was a risk factor at age 16 years but not at age 13 years or in 16-year-olds without high levels of depressive symptoms."
Yet she still says "
Dr Esther Crawley, a consultant paediatrician specialising in CFS/ME and the senior author of the report, said:
This is an important study because it shows that CFS/ME is much more common in teenagers than previously recognised. Treatment at this age is effective for most children but few have access to treatment in the UK. Children attending my specialist service at the Royal United Hospital in Bath only attend two days a week of school on average. This means that only the most severe cases are getting help. As paediatricians, we need to get better at identifying CFS/ME, particularly in those children from disadvantaged backgrounds who may be less able to access specialist care."
the CDF thing seems to have been a new way to 'justify' the research.
