This study aimed to examine the frequency of risk factors for chronic rhinosinusitis in outpatients attending the allergy clinics of Shahid Motahari Hospital in Urmia in 2021.</span></span><br> <span style="line-height:115%"><b><span new="" roman="" times="">Methods</span></b><span new="" roman="" times=""> This cross-sectional study was conducted on all outpatients aged 6 to 18 years diagnosed with chronic rhinosinusitis who visited the allergy clinic at Shahid Motahari Hospital in Urmia in 2021. The patients were categorized into two age groups (6-12 years and 13-18 years). Demographic information and medical histories were collected using a checklist and analyzed with SPSS software, version 22.</span></span><br> <span style="line-height:115%"><b><span new="" roman="" times="">Results</span></b><span new="" roman="" times=""> The prevalence of atopy in this study was 63.6%. Asthma was found in 63.9% of patients, and allergic rhinitis was present in 21.9%. The second most prevalent condition was GERD, with an occurrence rate of 20%. The most common sinonasal anatomical variation observed was adenoid hypertrophy (32.3%), followed by septal deviation in 11.5% of patients. No significant association was found between atopy and age, gender, tobacco smoke exposure, or the severity of chronic rhinosinusitis (p > 0.05).</span></span><br> <b><span style="line-height:115%"><span new="" roman="" times="">Conclusion</span></span></b><span style="line-height:115%"><span new="" roman="" times=""> This study investigated various risk factors associated with chronic rhinosinusitis. The overall prevalence of atopy, GERD, tobacco smoke exposure, adenoid hypertrophy, and septal deviation was significant. Further research with a larger sample size and a control group is essential to assess whether these factors are associated with the diagnosis and improved management of chronic rhinosinusitis.</span></span></span></span></p> Allergy, Atopy, Chronic rhinosinusitis, Epidemiology 188 195 http://hsm.umsu.ac.ir/browse.php?a_code=A-10-309-1&slc_lang=en&sid=1 Niloufar Ahmadi NiloufarAhmadi@gmail.com 10031947532846004185 10031947532846004185 No School of Medicine, Urmia University of Medical Sciences, Urmia, Iran Mir Reza Ghaemi Ghaemi.m@umsu.ac.ir 10031947532846004186 10031947532846004186 Yes Department of Pediatrics, School of Medicine, Urmia University of Medical Sciences, Urmia, Iran Hamid reza Houshmand Houshmand@gmail.com 10031947532846004187 10031947532846004187 No Department of Pediatrics, School of Medicine, Urmia University of Medical Sciences, Urmia, Iran Amir Nasimfar amirNasimfar@gmail.com 10031947532846004188 10031947532846004188 No Department of Pediatric Infectious Disease, Urmia University of Medical Sciences, Urmia, Iran
