Risk factor analysis of allergic rhinitis in 6-8 year-old children in Taipei

Area of Science:

• Pediatrics
• Environmental Health
• Epidemiology

Background:

• Allergic rhinitis (AR) incidence has risen significantly in Taiwan over the last 30 years.
• Understanding the prevalence and risk factors for AR in children is crucial for public health.
• Previous research has not comprehensively examined these factors in the Taiwanese pediatric population.

Purpose of the Study:

• To investigate the prevalence of rhinitis in young children in Taipei.
• To identify personal and environmental risk factors associated with rhinitis in early childhood.
• To provide evidence-based recommendations for AR prevention.

Main Methods:

• A cross-sectional survey involving 24,999 first-grade children (aged 6-8 years) in Taipei.
• Utilized modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaires completed by parents or caregivers.
• Employed logistic regression analysis to assess associations between rhinitis and various risk factors.

Main Results:

• The prevalence of rhinitis in the past 12 months was 42.8% among the surveyed children.
• Significant risk factors for rhinitis included male gender, early-life antibiotic use, bronchiolitis, diagnosed asthma, diagnosed eczema, and early-life cat exposure.
• Having older siblings was associated with a reduced risk of rhinitis.

Conclusions:

• Early-life antibiotic use and cat exposure in the first year of life are potential targets for rhinitis prevention.
• Public health strategies should consider factors like antibiotic stewardship and pet ownership in infancy.
• Tailored preventive measures can be developed based on identified risk factors and rhinitis severity in specific subgroups.
