Prevalence and Risk Factors of Allergic Rhinitis Among the Population in the Makkah Region, Saudi Arabia: A Cross-Sectional Study.

Background Allergic rhinitis (AR) is considered a high global disease burden; hence, the shortage of knowledge would lead to poor adherence to management and preventive measures and increase the exacerbation of AR symptoms. This study aimed to evaluate the prevalence and risk factors, and assess the knowledge and practices of the population regarding AR among the population in Makkah city, Saudi Arabia. Methodology This was an online survey cross-sectional study conducted in December 2022 via social media platforms (WhatsApp and Twitter) to collect data on participants' demographics, prevalence, risk factors, knowledge, and attitudes toward AR, using a validated Arabic version of a self-administered questionnaire. Results The study involved 466 participants. Of the participants, 55.8% were aged 31 to 45 years, and 286 (61.4%) were females. The prevalence of AR among the participants was 45%. The most common symptoms were a blocked nose (79.6%), sneezing (74.2%), and a runny nose (71.5%). Furthermore, the prevalence of rhinoconjunctivitis in this study was 56%. The most common inhalant allergen was house dust (73.0%). Only the age and history of asthma or eczema were significant factors associated with AR. Overall, most of the subjects (94.85%) had adequate knowledge regarding AR. Conclusion A high prevalence of AR was observed. Understanding the factors linked with AR is imperative to ensure better adherence to preventive management plans.
