Sample consisted of 1994 children (aged 5\u201312 years). Parents were interviewed by a paediatric headache specialist using a questionnaire that allowed the classification of headaches using the criteria of the Second Edition of the International Classification of Headache Disorders. The most severe headache type was classified (mutually-exclusive diagnoses). Prevalence and prevalence ratios were calculated overall, as well as by age, gender and race. The overall prevalence of migraine was 3.76%, non-significantly higher in boys (3.9%) than in girls (3.6%). Prevalence of probable migraine was significantly higher than the prevalence of migraine for all ages (overall prevalence of 17.1%). Chronic migraine (CM) happened in 0.8% (girls, 1.15%; boys, 0.5%). Infrequent episodic tension-type headache (ETTH) happened in 2.3% of the sample while prevalence of frequent ETTH was 1.6%. Probable TTH happened in 13.5%. Most children with migraine had consulted a medical doctor because of their headaches, and the proportion was higher among children with CM (93.7%). Prevalence of primary headaches is high in young children. Probable diagnoses are more common than full diagnoses. Consultation rates are elevated.<\/jats:p>","DOI":"10.1177\/0333102409361214","type":"journal-article","created":{"date-parts":[[2010,3,19]],"date-time":"2010-03-19T21:59:44Z","timestamp":1269035984000},"page":"1056-1064","source":"Crossref","is-referenced-by-count":72,"title":["Primary headaches in childhood \u2013 A population-based study"],"prefix":"10.1177","volume":"30","author":[{"given":"Marco A","family":"Arruda","sequence":"first","affiliation":[{"name":"Glia Institute, Ribeirao Preto, SP, Brazil."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincenzo","family":"Guidetti","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Neurology, Psychiatry and Rehabilitation, Sapienza University of Rome, Rome, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federica","family":"Galli","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Neurology, Psychiatry and Rehabilitation, Sapienza University of Rome, Rome, Italy."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regina CAP","family":"Albuquerque","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, S\u00e3o Jos\u00e9 do Rio Preto School of Medicine, S\u00e3o Jos\u00e9 do Rio Preto, SP, Brazil."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo E","family":"Bigal","sequence":"additional","affiliation":[{"name":"Merck Research Laboratories, Whitehouse Station, New Jersey, USA."},{"name":"Department of Neurology, Albert Einstein College of Medicine, Bronx, New York, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,3,19]]},"reference":[{"key":"bibr1-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a116014"},{"key":"bibr2-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-2982.2007.01288.x"},{"key":"bibr3-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1046\/j.1526-4610.2001.041007646.x"},{"key":"bibr4-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1007\/s11916-006-0047-6"},{"key":"bibr5-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-2982.2004.00681.x"},{"key":"bibr6-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-2982.2004.00680.x"},{"key":"bibr7-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000137039.08724.18"},{"key":"bibr8-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000199168.47044.13"},{"key":"bibr9-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1016\/j.pediatrneurol.2007.10.001"},{"key":"bibr10-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1212\/01.WNL.0000142044.22226.54"},{"key":"bibr11-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1177\/033310249601600205"},{"key":"bibr12-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.309.6957.765"},{"key":"bibr13-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1046\/j.1468-2982.1997.1704488.x"},{"key":"bibr14-0333102409361214","doi-asserted-by":"publisher","DOI":"10.1046\/j.1468-2982.1996.1608545.x"},{"key":"bibr15-0333102409361214","unstructured":"International Headache Society.
