Headache is a common symptom that constitutes a major health problem to all countries in the world. This study was conducted to estimate the prevalence of migraine and tension -type headaches(TTH), its associated occupational risk factors among Shiraz hospitals staffs, and to report on clinical characteristics of migraine and TTH with using the International Headache Society (IHS) diagnosis criteria. A random sample of 1023 staffs constituting a 20% sample of the hospitals staff population was selected. Sampling method was categorical random sampling. Within each group sampling was carried out systematically. Data were collected by screening questionnaire followed by clinical interviews, general physical and neurological examination, and diagnostic criteria of IHS. Prevalence of migraine, TTH and coexisting migraine and TTH were estimated as 11.2% (115 cases), 19.5% (199 subjects) and 3.2% (33 subjects) respectively. In this study , clinical characteristics of headache including type, site, number , intensity ,concomitant symptom of headaches had been surveyed. TTH and migraine headaches were significantly associated with self reported abnormal sleep pattern and female gender (P < 0.001). Also TTH was negatively associated with total 24hr duration of sleep and history of involvement in second job significantly (P<0.026). The average of prevalence of migraine and TTH were lower than their counter parts in western countries but higher than previous studies conducted in other Asian countries. Clinical characteristics were almost parallel with IHS criteria, headache- related missed work rates were higher for subjects with migraine headache, and also TTH and migraine were separate disorders and were not as a part of a continuum of headache disorders. Headache disorders deserve more attention, especially concerning strategies leading to adequate primary prevention, diagnosis and treatment.
