We thank Ng et al for their interest in our article.1They raise concern about lack of data on nasal symptoms and our definition for positive skin-prick test results. Using the rhinitis definition of a positive parent report to the question “In the past 12 months, has your child ever had a problem with sneezing, or a runny, or a blocked nose when he/she did not have a cold or flu?” we found a strong association between rhinitis and habitual snoring (p < 0.001) in our cohort of 681 infants. In multivariate logistic regression model with habitual snoring as the dependent variable, the adjusted odds ratio for rhinitis was 2.5 (confidence interval, 1.7 to 4.0) and atopy (defined as positive skin-prick test result to an aeroallergen or food allergen was 1.9 (confidence interval, 1.2 to 2.9). Infants with positive skin-prick test results to aeroallergens compared to infants with negative skin-prick test results to all allergens had a trend for higher prevalence of habitual snoring (20.4% vs 12.9%, p = 0.05); and infants with positive skin-prick test results to food allergens compared to infants with all negative skin-prick test results to all allergens had a significantly higher prevalence of habitual snoring (22.5% vs 12.9%, p = 0.01). It is important to mention that at age 1 year, the prevalence of atopy to food allergens was much higher than that to aeroallergens. Therefore, a smaller sample size with lower power for aeroallergens could potentially explain the lack of significance for that group. At age 2 years, we have reported a dramatic increase in aeroallergen atopy.2Given these findings, we propose to study the independent relationship between atopy to aeroallergens and habitual snoring at age 2 years. Our definition of a positive skin-prick test result is the standard proposed by the practice parameter committee of the Academy of Allergy, Asthma, and Immunology.3 Unfortunately, as pointed out by Ng et al, there are some limitations to this criterion. In summary, our data suggest that both rhinitis and atopy are independently associated with increased risk for habitual snoring in infants.
