Nevertheless, few studies have assessed the prevalence of headache and the role of socio\u2010demographic aspects in very low\u2010income communities.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods.\u2014<\/jats:bold>\n                    A cross\u2010sectional, population\u2010based study was undertaken. Door\u2010to\u2010door interviews with 383 people were conducted. Individuals were aged greater than 18 years, randomly selected from the \u201cParaisopolis\u201d shanty town in S\u00e3o Paulo, Brazil. The degree of the association was calculated through prevalence ratios and adjusted with backward logistic regression by gender, age, and some socio\u2010demographic factors, including living conditions.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results.\u2014<\/jats:bold>\n                    The estimated 1\u2010year prevalence of headache, migraine, chronic migraine, and tension\u2010type headache were 47% (CI 95%: 39.5\u201052.6%), 20.4% (CI 95%: 16.6\u201024.9%), 8.4% (CI 95%: 6.1\u201012.0%), and 6.2% (CI 95%: 3.3\u20109.8%), respectively. Migraine was more prevalent in women and among employed people. No other relationship was found. The overall prevalence of migraine and chronic migraine in this very low\u2010income community were high and migraine was associated with gender and job status.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion.\u2014<\/jats:bold>\n                    The overall prevalence of migraine and chronic migraine in this very low\u2010income community were high and tension\u2010type headache was low. A paradox was noted in the employment status and income association, one would expect higher levels of migraine in a low\u2010income population, but higher numbers were found in those employed vs unemployed. These findings will need to be replicated in other population samples.\n                  <\/jats:p>","DOI":"10.1111\/j.1526-4610.2011.01899.x","type":"journal-article","created":{"date-parts":[[2011,6,3]],"date-time":"2011-06-03T13:43:16Z","timestamp":1307108596000},"page":"971-979","source":"Crossref","is-referenced-by-count":28,"title":["The Prevalence of Migraine and Probable Migraine in a Brazilian Favela: Results of a Community Survey"],"prefix":"10.1111","volume":"51","author":[{"given":"Giancarlo","family":"Lucchetti","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario F.
