One-Year Follow-Up of Headache in an
Adult General Population
Boardman HF, Thomas E, et al.
Posted: May 2005
Objective: To investigate variation in
headache occurrence and characteristics over 1 year.
Methods: Postal survey to a random general population
sample of 5000 adults aged 18 years plus, with follow-up survey to
all baseline responders at 1 year and a subsample of 500 being
surveyed at 2-monthly intervals between the baseline and 1-year
Results: A total of 1589 responded to the 1-year
follow-up and 282 of the subsample responded to all five surveys
at 3-mothly intervals. Among 1-year respondents with recent
headache at baseline (defined as occurring during the previous 3
months), nearly all also reported headache during the follow-up
year. One-third of respondents without recent headache at baseline
reported a new episode of headache during the follow-up in at least
one headache characteristic. These findings were replicated in the
sample completing the 3-monthly surveys. Although most of this
subgroup reported their headache occurrence status was unchanged
during each 3-month period, only a few (3%) respondents with
headache in each period reported no variation at all in headache
characteristics during the study.
Conclusions: While prevalence of recent headache was
stable over time for individuals, there was considerable variation
in headache characteristics.
