In this study, patterns of analgesic use among persons with headache i
n the general Swedish population were analyzed in association with hea
lth factors, health care utilization, sociodemographic factors, end li
fe-style. Data from the Swedish Survey of Living Conditions for the P-
year period 1988 through 1989 were used. In this survey, a probability
sample of the Swedish population aged 16 years and older was intervie
wed. Persons with headache were identified by the question, ''Have you
(during the last 2 weeks) had recurrent headache or migraine?'' Analg
esic use was defined by the question, ''Have you (during the last 2 we
eks) used prescription or nonprescription analgesics?'' Persons who an
swered both these questions were included in the present study, yieldi
ng a study population of 11 975 persons. Sixteen percent of all women
and 8.2 percent of all men reported headache. Seventy-four percent of
all women with headache reported analgesic use as compared to 64% of a
ll men with headache. Analgesic use increased with increasing age amon
g women but not men. While few of the studied factors were associated
with analgesic use among persons with headache, the associations found
differed by gender. Poor social network and musculoskeletal pain were
associated with analgesic use among men with headache; age, being und
erweight, and visits to a physiotherapist were associated with analges
ic use among women with headache. Those studying medication use among
persons with headache might consider including these factors in future
studies to help better understand the mechanisms behind the decision
to use or avoid analgesics.
