OBJECTIVE: TO analyze patterns of prescription and nonprescription ana
lgesic use in the general Swedish population, in association with pred
isposing factors, enabling factors, need, and health behavior. DESIGN:
Cross-sectional interview survey. SETTING: The Swedish Surveys of Liv
ing Conditions for the 2-year period 1988-1989. PARTICIPANTS: A probab
ility sample of all inhabitants of Sweden aged 18-84 years (n = 11 996
). MAIN OUTCOME MEASURES: Prescription and nonprescription analgesic u
se during a 2-week period. RESULTS: Women reported use of analgesics b
oth with and without prescriptions to a greater extent than did men. A
mong women, 12.2% reported prescription analgesic use and 30.4% report
ed nonprescription analgesic use. The corresponding proportions among
men were 7.2% and 20.0%, respectively. In the descriptive analyses, pr
escription analgesic use was most common among persons aged 45 years a
nd older, while use of nonprescription analgesics was most common in p
eople aged 18-44 years. The polychotomous logistic regression analyses
showed that headache and musculoskeletal pain were strongly associate
d with prescription analgesic use to a similar extent among men and wo
men. Headache was associated with nonprescription analgesic use among
men and women, but a gender difference was found in the association be
tween musculoskeletal pain and nonprescription analgesic use. Women wi
th musculoskeletal pain used nonprescription analgesics to a greater e
xtent than did men with musculoskeletal pain. Poor health - measured a
s self-perceived health status and physical function - and high use of
health care were related only to prescription analgesic use. Smoking
and being overweight were associated with prescription analgesic use a
mong men and with nonprescription analgesic use among women; alcohol c
onsumption was associated with both types of analgesic use only among
women. CONCLUSIONS: This study shows that men and women differ in thei
r choice between prescription and nonprescription analgesics and that
the choice between prescription and nonprescription analgesics is infl
uenced by an individual's pain, self-perceived health, and lifestyle.
