Abstract
Background: Allergic rhinitis (AR) is a disease with a high global disease burden and significant morbidity and expense. Risk factors are not well understood.
Objective: The objective of our project is to study the prevalence and risk factors of AR in children living in the Bangkok area.
Methods: A cross-sectional, multi-center survey using new GAN core questionnaires on current AR and risk factors was completed by 3,074 parents of children aged 6-7 years and by 3,217 children aged 13-14 years, directly.
Results: The prevalence of current AR in children aged 6-7 years and 13-14 years was 15.0% (95% confidence interval [CI]:13.8-16.3%) and 17.5% (95% CI: 16.2-18.8%), respectively. The prevalence of severe AR in children aged 6-7 years and 13-14 years was 1.0% (95% CI: 0.6-1.3%) and 1.9% (95% CI: 1.4-2.4%), respectively. Co-morbidity with asthma and eczema was 27.1% and 24.6%, respectively. Significant factors associated with AR include parental history of asthma (p = 0.025), parental history of AR (p < 0.001), parental history of eczema (p < 0.001), lower respiratory tract infection in the first year of life (p < 0.001), breastfeeding (p = 0.019), current use of paracetamol (p < 0.001), exercise (p < 0.001), current cat exposure (p = 0.008), and truck traffic on the street of residence (< 0.001).
Conclusion: AR is a common disease among children residing in Bangkok. This study confirms that a family history of atopy (asthma, AR, and eczema), antibiotics given in the first year of life, current paracetamol use, exercise, current cat exposure, and truck traffic on the street of residence are important and significant risk factors for AR symptoms.
