[BDSP. Notice produite par INIST 3PR0x9Sq. Diffusion soumise à autorisation]. Context. - Tension-type headache is a highly prevalent condition. Because few population-based studies have been performed, little is known about its epidemiology. Objectives. - To estimate the 1-year period prevalence of episodic tension-type headache (ETTH) and chronic tension-type headache (CTTH) in a population-based study ; to describe differences in 1-year period prevalence by sex, age, education, and race ; and to describe attack frequency and headache pain intensity. Design. - Telephone survey conducted 1993 to 1994. Setting. - Baltimore County, Maryland. Participants. - A total of 13 345 subjects from the community. Main Outcome Measures. - Percentage of respondents with diagnoses of headache using International Headache Society criteria. Workdays lost and reduced effectiveness at work, home, and school because of headache, based on self-report. Results. - The overall prevalence of ETTH in the past year was 38.3%. Women had a higher 1-year ETTH prevalence than men in all age, race, and education groups, with an overall prevalence ratio of 1.16. Prevalence peaked in the 30-to 39-year-old age group in both men (42.3%) and women (46.9%). Whites had a higher 1-year prevalence than African Americans in men (40.1% vs. 22.8%) and women (46.8% vs 30.9%). Prevalence increased with increasing educational levels in both sexes, reaching a peak in subjects with graduate school educations of 48.5% for men and 48.9% for women. The 1-year period prevalence of CTTH was 2. (...)
