The prevalence of allergic rhinitis (AR) among children has increased markedly in Beijing during-the last two decades. The purpose of this study was to estimate the prevalence of AR and to identify indoor risk factors for AR among preschool children. A cross-sectional questionnaire survey was conducted in Beijing, 2011. Parents of 5388 3-6 years old children (65% response rate) from randomly selected kindergartens in Beijing participated in this study. A Chi-square test and multiple logistic regressions were used to identify risk factors. Our survey found that the prevalences of AR symptoms ever, AR symptoms current (AR symptoms in the last 12 months) and doctor-diagnosed AR are 49.5%, 45.6% and 7.8%, respectively. Confounding factors for AR symptoms and/or doctor-diagnosed AR are gender, age, family allergic history, breastfeeding and current environmental tobacco smoke (ETS). New furniture, condensation on window pane and cockroaches are risk factors for both AR symptoms ever and AR symptoms current. Risk factors for AR symptoms ever include the use of humidifier and incense. A risk factor for AR symptoms current is mosquitoes/flies. Risk factors for doctor-diagnosed AR include living close to a main road or highway, visible mold spots and current pet keeping. A protective factor against doctor-diagnosed AR is opening the child's bedroom window in winter (aOR 0.66, 95% CI 0.48, 0.92). We found that the greater the number of home environmental risk factors, the higher risk of AR. A number of home environmental factors are associated with AR among preschool children.
