This study was designed to assess the prevalence of asthma in 13-14-year-old adolescents in Karaj, Alborz province in Iran, using the international study of asthma and allergies in childhood (ISAAC) questionnaire.\u00a0\r\nTotally 950 adolescents attending 40 schools located in 4 regions of Karaj city were enrolled in the survey. The Persian version of the ISAAC questionnaire was filled by 13-14-year-old students. Multi-stage clustered random sampling was used to divide the city of Karaj into four educational districts.\r\nEver wheezing was reported in 22% of the individuals; 10.52% claimed to have wheeze in the last 12 months and 22.73% had during or after exercise. The experience of wheezing in the last 12 months was more prevalent among males (11.73% vs. 9.38%; p&lt;0.05). However, having a history of asthma was higher among males (7.55% vs. 3.47%; p&lt;0.05). History of hospitalization (60.8%), family history of asthma (49.4%), and history of food allergy (42.3%) were found to be the most frequent characteristics significantly associated with\" ever wheezing\" (p&lt;0.05).\r\nThe prevalence of wheezing in the last 12 months, as a major index of current asthma, was 10% which was close to the national average. However, nocturnal cough and exercise-induced wheezing were higher in Karaj compared to other cities of Iran; which could be related to the high level of air pollution in this industrial area.<\/jats:p>","DOI":"10.18502\/ijaai.v19i6.4935","type":"journal-article","created":{"date-parts":[[2020,12,22]],"date-time":"2020-12-22T07:48:17Z","timestamp":1608623297000},"source":"Crossref","is-referenced-by-count":6,"title":["Prevalence of Asthma Symptoms in 13-14-year-old Adolescents in Karaj"],"prefix":"10.18502","author":[{"given":"Marzieh","family":"Tavakol","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyde Marzie","family":"Fatemi Abhari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatemeh","family":"Moosaie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mina","family":"Rasmi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmood","family":"Bakhtiyari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leila","family":"Keikavoosi-Arani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiomars","family":"Poorrostami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Homa","family":"Sadri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7770","published-online":{"date-parts":[[2020,12,21]]},"container-title":["Iranian Journal of Allergy, Asthma and Immunology"],"original-title":[],"link":[{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/IJAAI\/article\/download\/4935\/4129","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/IJAAI\/article\/download\/4935\/4129","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,12,17]],"date-time":"2024-12-17T11:16:02Z","timestamp":1734434162000},"score":1,"resource":{"primary":{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/IJAAI\/article\/view\/4935"},"secondary":[{"URL":"https:\/\/ijaai.tums.ac.ir\/index.php\/ijaai\/article\/view\/2797","label":"UNIVERSITY"},{"URL":"https:\/\/publish.kne-publishing.com\/index.php\/IJAAI\/article\/view\/4935","label":"PUBLISHER"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,12,21]]},"references-count":0,"URL":"https:\/\/doi.org\/10.18502\/ijaai.v19i6.4935","relation":{},"ISSN":["1735-5249","1735-1502"],"issn-type":[{"value":"1735-5249","type":"electronic"},{"value":"1735-1502","type":"print"}],"subject":[],"published":{"date-parts":[[2020,12,21]]}}}
