BACKGROUND: There is abundance of epidemiological studies of @entity10 in developed and western countries; however, data in developing countries and in Egypt are still lacking. This study aims to detect the prevalence of @entity12967 in both urban and rural sectors in Fayoum governorate, Egypt. METHODS: A total of 2600 subjects were included using multi-stage stratified systematic random sampling, with respondent rate of 91.3  %. A pre-designed Arabic version, interviewer-administered, pilot tested structured questionnaire was developed according to The International Classification of @entity2794 , 3rd edition (beta version), and this questionnaire was validated and the strength of agreement in @entity10 diagnosis was good. RESULTS: The 1-year @entity10 prevalence was 51.4  %, which was more prevalent in urban dwellers. The most common primary @entity10 type was episodic tension @entity10 (prevalence; 24.5  %), followed by @entity2704 (prevalence; 17.3  %), both types peaked in midlife. @entity2794 were more common in females with exception of @entity2686 that showed the expected male dominance. The risk of @entity2794 increased more than one fold and half when the @entity1 were females, married, and in those with high education. More than 60  % of our @entity1 did not seek medical advice for their headaches problem; this percentage was higher in rural areas. CONCLUSIONS: @entity12967 are common in Egypt; prevalence rate was comparable with western countries with exception of episodic tension @entity10 . Still @entity10 is under-estimated and under-recognized in Egypt and this problem should be targeted by health care providers.
