This study looked at alcohol consumption:
Goedendorp MM, Knoop H, Schippers GM, Bleijenberg G. The lifestyle of patients with chronic fatigue syndrome and the effect on fatigue and functional impairments. J Hum Nutr Diet. 2009 Jun;22(3):226-31. Epub 2009 Feb 17.
Here are a few notes I made on it (not all on alcohol):
Conclusions: CFS patients tend to lead a healthier lifestyle compared
to the general Dutch population. However, no relationship was found
between lifestyle factors and fatigue severity and functional
impairments in CFS.
Useful finding.
They make the second line sound like a bad thing but it's not necessarily at all.
A couple of other findings:
Out of the 247, there was only one person who had an "unhealthy alcohol intake" defined as follows:
"Female patients drinking more than two alcohol units a day and male patients drinking more than
three alcohol units a day were defined as having an unhealthy alcohol intake"
Regarding, "Significantly more female CFS patients abstained from alcohol", it's interesting as this is actually all from the 18-44 group. In the 45-65 group, numerically there were fewer CFS patients who abstained than the normal population.
Alcohol abstinence % (n) P
Female CFS Age:1844 35.5 (43/121) <0.001
Dutch population 20.1 (278/1384)
Alcohol abstinence % (n) P
Female CFS Age:4565 17.9 (10/56) 0.360
Dutch population 19.9 (342/1722)
The numbers for male were too small:
Alcohol abstinence % (n) P
Male CFS Age:1844 25.0 (10/40) *
Dutch population 9.6 (130/1356)
Alcohol abstinence % (n) P
Male CFS Age: 4565 13.3 (4/30) * 33.3 (2/6) * 66.7 (4/6) * 0 (0/6) *
Dutch population 8.2 (138/1688)
BOLD, P < 0.01 was considered statistically significant. *These differences were too small to test.
BMI, body mass index; CFS, chronic fatigue syndrome.
~~~~~~~~~~~
"In addition, no differences in fatigue
severity (P = 0.525) or functional impairments
(P = 0.055) were found between patients having none or
one unhealthy lifestyle factor and patients having two or
more unhealthy lifestyle factors."
P=0.055 is nearly significant.
What they don't say is one can see from the table that is the opposite of what one might expect: on all six measures of "unhealthiness", the people with the "unhealthy" lifestyles score numerically better on functional impairment i.e. are less functionally impaired.
Also for BMI, there is nearly a statistical significant difference between those with an unhealthy BMI (BMI>25) and those with a healthy BMI (p=0.039).
Those with an unhealthy BMI have a better fatigue score! (47.7 (SD: 5.1) vs 50.2 (SD:5.0))
