Prevalence and Risk Factors of Allergic Rhinitis; A systematic Review

Abstract

Allergic rhinitis (AR), an immunoglobulin E-induced nasal infection, significantly impacts nasal mucosa function and quality of life. Its incidence has risen globally, showing variations across income categories. This systematic study aimed to determine the prevalence and risk factors of AR. Data were sourced from PubMed/Medline, Scopus, and Embase, following PRISMA guidelines. English-language articles (2010–2023) discussing AR prevalence and risk factors were included. A total of 15 articles were reviewed, with surveys and national database analyses being predominant (n=15). The search initially yielded 95 studies, of which 15 met inclusion criteria. Enhanced knowledge of prevalence and risk factors is crucial for future treatment improvements. The prevalence of AR has surged, necessitating evidence-based assessments of risk factors. For adults, risk factors include smoking, asthma, family history of AR, drug and food allergies, pollen allergy history, antibiotic use, occupational dust exposure, home renovation, and middle school education. In children, passive smoking, asthma, family history of AR, allergies, eczema, pet ownership, seafood consumption, male gender, and breastfeeding were identified as risk factors. The study highlights AR prevalence\'s correlation with allergic diseases, familial allergy history, and environmental factors. Comprehending these associations is pivotal for enhancing adherence to preventive management plans.
