PREVALENCE OF PRIMARY HEADACHE SYNDROME IN ADULTS IN THE QASSIM REGION OF SAUDI-ARABIA

Background and Purpose: Headache occurs worldwide, but documentation o n the burden of headache in Saudi communities is quite limited. The ai m of this study was to determine the prevalence of primary headache in a rural community in the Qassim region of Saudi Arabia. Methods: A do or-to-door survey of subjects older than 15 years of age was used for completion of a structured questionnaire to determine headache types b ased on defined criteria. Physical examination was used to exclude sec ondary causes. Results: Of 5891 inhabitants, 473 suffered from headach es. The crude lifetime prevalence rate was 8% (95% CI, 7.3% to 8.7%) a nd with age adjustment was 9.3% (8.6% to 10%). Headache sufferers were predominantly women. The age-specific rate increased progressively, p eaking in the sixth decade. Tension-type headache diagnosed in 185 sub jects predominated (3.1%), while the prevalence of migraine was 2.6%. Conclusion: The findings agree with the reported prevalence of 10% to 12% in other communities in the Kingdom of Saudi Arabia, but lower tha n the rates in Western countries. The lower rates are probably related to sociocultural factors.
