Abstract

Objectives.—The aim of the present study was to estimate the prevalence of migraine among Croatian adults. This is the first epidemiological study of migraine in Croatia in which the operational diagnostic criteria of the International Headache Society have been applied.

Methods.—The study population consisted of all residents (aged 15 to 65 years) of Bakar, County of The Coast and Gorski Kotar, Croatia. A population-based survey was undertaken using a “face-to-face, door-to-door” interview method. The participation rate was 73.3%. All participants were screened for headache history according to the International Headache Society criteria. Headache screen positive responders (65.7%) were interviewed by trained medical students with a structured detailed interview focused on migraine.

Results.—A total of 720 lifetime migraineurs were identified. The lifetime prevalence of migraine was 22.9% (95% confidence interval, 20.9 to 25.1) in women, 14.8% (95% confidence interval, 13.1 to 16.8) in men, and 19% (95% confidence interval, 17.6 to 20.5) in both sexes. The highest lifetime prevalence of migraine was in women in the age group 40 to 49 years (38.1%). Among 636 active migraineurs, 399 (62.7%) were women and 237 (37.3%) were men; 55.8% had migraine without aura, 35.2% migraine with aura, and 6.9% migraine both with and without aura. The 1-year prevalence of migraine, migraine without aura, migraine with aura, and migraine both with and without aura in women was 18%, 11.3%, 8.6%, and 2.2%, respectively. In men, the 1-year prevalence of migraine, migraine without aura, migraine with aura, and migraine both with and without aura was 12.3%, 7.3%, 3%, and 0.7%, respectively.

Conclusions.—The prevalence of migraine in this Croatian population showed rates quite similar to those reported in neighboring countries, such as Italy and France. Further studies are needed to estimate the prevalence rates of migraine in the total Croatian population.
