It is sometimes difficult to analyze data described in this way and to understand relations between variables. Graphical methods such as correspondence analysis are more convenient and useful. Our paper describes an application of correspondence analysis to epidemiological research. We apply the basic concepts of correspondence analysis like profiles, chi-square distance to medical data concerning prevalence of asthma. We aim at describing the relationship between asthma, region, and age. The data presented in this paper come from Epidemiology of Allergy in Poland (ECAP) survey in years 2006\u20132008. Correspondence analysis shows that there is a fundamental difference in the structure of age groups for people with symptoms compared to those who have declared asthma (regardless of the level of symptoms of asthma and the level of declaration). The variable which best differentiates declared asthma in all regions is \u201cwheezing and whistling.\u201d Correspondence analysis also shows significant differences between locations. Our analyses are performed in the R package \u201cca\u201d.<\/jats:p>","DOI":"10.1155\/2013\/597845","type":"journal-article","created":{"date-parts":[[2013,1,16]],"date-time":"2013-01-16T21:04:08Z","timestamp":1358370248000},"page":"1-8","source":"Crossref","is-referenced-by-count":5,"title":["The Prevalence of Asthma and Declared Asthma in Poland on the Basis of ECAP Survey Using Correspondence Analysis"],"prefix":"10.1155","volume":"2013","author":[{"given":"M.","family":"Zalewska","sequence":"first","affiliation":[{"name":"Department of Environmental Hazards Prevention and Allergology, Medical University of Warsaw, Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Furma\u0144czyk","sequence":"additional","affiliation":[{"name":"Department of Environmental Hazards Prevention and Allergology, Medical University of Warsaw, Warsaw, Poland"},{"name":"Department of Applied Mathematics, Warsaw University of Life Sciences, Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Jaworski","sequence":"additional","affiliation":[{"name":"Department of Environmental Hazards Prevention and Allergology, Medical University of Warsaw, Warsaw, Poland"},{"name":"Department of Econometrics and Statistics, Warsaw University of Life Sciences, Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Niemiro","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics, Informatics and Mechanics, University of Warsaw, Warsaw, Poland"},{"name":"Faculty of Mathematics and Computer Science, Nicolaus Copernicus University, Toru\u0144, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Samoli\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Environmental Hazards Prevention and Allergology, Medical University of Warsaw, Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"2","year":"2008"},{"issue":"9111","key":"12","doi-asserted-by":"crossref","first-page":"1225","DOI":"10.1016\/S0140-6736(97)07302-9","volume":"351","year":"1998","journal-title":"The Lancet"},{"issue":"4","key":"13","doi-asserted-by":"crossref","first-page":"687","DOI":"10.1183\/09031936.96.09040687","volume":"9","year":"1996","journal-title":"European Respiratory Journal"},{"key":"6","first-page":"8","volume":"68","year":"2008","journal-title":"Allergy"},{"key":"11","year":"1984"},{"key":"7","year":"2010"},{"issue":"5","key":"8","first-page":"16","volume":"24","year":"2007","journal-title":"Nursing Journal of Chinese People's Liberation Army"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.5897\/SRE10.964"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1023\/A:1014586129113"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2013\/597845.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2013\/597845.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2013\/597845.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,21]],"date-time":"2017-06-21T05:45:47Z","timestamp":1498023947000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2013\/597845\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":9,"alternative-id":["597845","597845"],"URL":"https:\/\/doi.org\/10.1155\/2013\/597845","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013]]}}}
