The purpose of this study was to explore risk factors related to asthma prevalence among preschool and school-aged children using a representative national dataset from the Korea National Health and Nutrition Examination Survey KNHANES conducted from 2009–2011. We evaluated the demographic information, health status, household environment, socioeconomic status, and parents’ health status of 3,542 children aged 4–12 years. A sex-stratified multivariate logistic regression was used to obtain adjusted prevalence odds ratios ORs and 95% confidence intervals after accounting for primary sample units, stratification, and sample weights. The sex-specific asthma prevalence in the 4- to 12-year-old children was 7.39% in boys and 6.27% in girls. Boys and girls with comorbid atopic dermatitis were more likely to have asthma than those without atopic dermatitis boys: OR = 2.20, p = 0.0071; girls: OR = 2.33, p = 0.0031. Boys and girls with ≥1 asthmatic parent were more likely to have asthma than those without asthmatic parents boys: OR = 3.90, p = 0.0006; girls: OR = 3.65, p = 0.0138. As girls got older, the prevalence of asthma decreased OR = 0.90, p = 0.0408. Girls residing in rural areas were 60% less likely to have asthma than those residing in urban areas p = 0.0309. Boys with ≥5 family members were more likely to have asthma than those with ≤3 family members OR = 2.45, p = 0.0323. The factors related to asthma prevalence may differ depending on sex in preschool and school-aged children. By understanding the characteristics of sex-based differences in asthma, individualized asthma management plans may be established clinically.
