Abstract
Background and Objectives: At present, no data are available on risk factors of migraine and tension – type headaches among Iranian hospital staffs. Therefore, we identified socio- demographic and occupational risk factors of migraine and tension- type headaches among hospital staffs of Shiraz (Iran).
Materials and Methods: This was a case- control study using prevalence data a random sample (stratified random sample) of 1023 hospital staffs of Shiraz (Iran). Subjects were stratified by personnel category (nurse, clerical and manual). For each patient, two controls of the same sample were selected who had never been diagnosed as having migraine or tension- type headaches. Logistic regression was used for data analysis.
Results:. The subjects were 115(11.5%) patients with migraine and 199(19.5%) patients with tension type headaches diagnosed both by IHS criteria and clinical examination Of 115 patient with migraine were 97 (84.3%) female and 18 (15.7%)male, and of 199 patient with tension type headache were 154(77.4%)female and 45( 22.6%)male. The most prevalence of migraine and tension type headache were among 30-39(16.5% ) age group and 40-49 (25.8%) age group. In multiple logistic regression odds for migraine in hospital staffs who had positive family history of headache was 2.7(95%CI: 1.6-4.5) and for tension- type headaches was 1.8 (95%CI: 1.1-2.9). The odds ratios for migraine and tension type headaches in hospital staffs who had abnormal sleeping pattern were 1.8 (95%CI: 1.0-3.1) and 2.6 (95%CI: 1.5-4.5) times higher than those with normal sleeping pattern. Migraine was gender dependent and females odds was 2.5times of males (95%CI: 1.2-5.2). Tension- type headache was significantly associated with history of second job, inadequacy sleep and systolic blood pressure (P<0.042) too. Migraine and tension type headaches were not significantly associated with other factors.
Conclusion: Family history of headache and sleeping disorders had been identified as the most significant effects on occurrence of migraine and tension- type headaches in hospital staffs of Shiraz(Iran). Migraine was gender dependent.Tension- type headache was significantly associated with history of second job, inadequacy sleep and systolic blood pressure.
