Study on relationship between prevalence of allergic rhinitis and living environment in preschool children in Haikou City

Abstract

Abstract: Objective To investigate the relationship between the prevalence of allergic rhinitis and the indoor environment of the living room in preschool children in Haikou City. Methods A multi-stage stratified cluster random sampling method was used to select 3 049 preschool children from eight kindergartens in Xiuying District and Longhua District of Haikou City from December 2020 to January 2021,and a questionnaire survey was conducted using the general information questionnaire,the core questionnaire and survey and research questionnaire on building dampness and health of the international study of asthma and allergies in childhood（ISAAC）. Results The prevalence of allergic rhinitis among 3 049 preschool children in Haikou City was 7.15%. The multi-factor logistic regression analysis showed that age（OR=1.272,95%CI：1.100-1.470）,only child（OR=1.547, 95%CI：1.152-2.077）,family history（OR=3.658,95%CI：2.692-4.971）,mildew and water damage on the floor and wall in the one year before pregnancy（OR=1.506,95%CI：1.020-2.221）,newly renovated house when children are aged 0-1 years old（OR=1.712, 95%CI：1.013-2.893）,new furniture within the last 12 months（OR=1.437,95%CI：1.017-2.030）,feeling damp air（OR=1.398, 95%CI：1.044-1.873） were risk factors for rhinitis,and gender（OR=0.669,95%CI：0.499-0.898） was protective factor for allergic rhinitis（P<0.05）. Conclusions The prevalence of allergic rhinitis is higher in preschool children aged 6-7 years old. The prevalence of allergic rhinitis in female preschool children is lower than that in male preschool children,and the prevalence of allergic rhinitis in only child is higher than that in non-only child. The children with a family history of allergic rhinitis are more likely to be affected. The damp air in the indoor environment,mildew and water damage on the floor and wall,and new decoration and new furniture are risk factors for allergic rhinitis in preschool children. The parents should pay attention to the ventilation and cleanliness of children's rooms in daily life,and try to avoid preschool children living in newly renovated houses with new furniture or choose healthy and environmentally friendly materials in the process of decoration and purchase of furniture.
