Abstract: | The objective was to
examine potential trigger factors
of migraine and tension-type
headache (TTH) in clinic
patients and in subjects from
the population and to compare
the patients’ personal experience
with their theoretical knowledge.
A cross-sectional study was
carried out in a headache centre.
There were 120 subjects
comprising 66 patients with
migraine and 22 with TTH
from a headache outpatient
clinic and 32 persons with
headache (migraine or TTH)
from the population.
A semistructured interview
covering biographic data,
lifestyle, medical history,
headache characteristics
and 25 potential trigger factors
differentiating between
the patients’ personal experience
and their theoretical knowledge
was used. The most common
trigger factors experienced
by the patients were weather
(82.5%), stress (66.7%),
menstruation (51.4%) and
relaxation after stress (50%).
The vast majority of triggers
occurred occasionally and
not consistently. The patients
experienced 8.9±4.3 trigger
factors (range 0–20) and they
knew 13.2±6.0 (range 1–27).
The number of experienced
triggers was smallest in the
population group (p=0.002),
whereas the number of triggers
known did not differ in the
three study groups. Comparing
theoretical knowledge with
personal experience showed
the largest differences for
oral contraceptives (65.0 vs.
14.7%, p<0.001), chocolate
(61.7 vs. 14.3%, p>0.001)
and cheese (52.5 vs. 8.4%,
p<0.001). In conclusion,
almost all trigger factors are
experienced occasionally and
not consistently by the majority
of patients. Subjects from
the population experience
trigger factors less often
than clinic patients.
The difference between
theoretical knowledge and
personal experience is largest
for oral contraceptives, chocolate
and cheese. |
