Abstract

Allergic rhinitis and eczema are two common global diseases that can lead to impaired quality of life. Determining the prevalence of these allergic disorders can be useful in planning prevention and treatment. This study aimed to investigate the prevalence and severity of allergic rhinitis and eczema in adolescents living in Yazd city. Using an electronic questionnaire based on the Global Asthma Network (GAN) core questionnaire, 5141 adolescents aged 13–14 years were cross-sectionallysurveyed. The prevalence of current symptoms of rhinitis turned out to be 36.3%, proving significantly higher in boys (p=0.009). Moreover, the prevalence of allergic rhinitis and rhinoconjunctivitis in the past year leveled at 12.4% and 10.5%, respectively; however, the former was significantly higher in females (p=0.014). Additionally, severe rhinoconjunctivitis was observed in 0.2% of the participants with no gender preference (p=0.09). Confirmed hay fever by a doctor was reported in 13.2% of adolescents, significantly higher in males (p<0.001). The prevalence of current itchy rash and current eczema was found to be 5.5%, and 2.9%, respectively, with no difference in terms of gender. Severe atopic eczema and eczema confirmed by a doctor were seen in 0.4% and 5% of the participants, no gender preference was identified. Concurrent prevalence of current rhinoconjunctivitis and eczema was detected in 1% of the participants. Despite the increasing trend of allergic diseases in most parts of the world, the prevalence of rhinoconjunctivitis and eczema in adolescents has not increased in Yazd in the last two decades, and this city is located in a low to moderate prevalence area.
