Does anyone know where the frequently quoted estimate of 20,000 people with ME in NZ comes from?
Somewhere on the forum (sorry, can't remember where) prevalence rates of 0.2% (Fukuda) and 0.11% (CCC) were mentioned, based on overseas studies.
If, for ease of calculation, we assume a population of 5million, then:
0.2% = 10,000
0.11% = 5,500
So why are we using 0.4% ? Have there been any NZ prevalence studies done to support this?
I'm just a bit worried about our credibility with so many conflicting figures being thrown about. Just one example: you frequently see the statement that ME is twice as common as MS. The estimate for MS in NZ is 4,000 so that doesn't match with the 20,000.
I can see that for advocacy purposes a higher number sounds more impressive but I fear that could backfire if it can't be backed up by some solid stats.
