Abstract

BACKGROUND:

Children with allergic disease have multiple risk factors for accidental injuries.

OBJECTIVE:

To determine the prevalence of injuries requiring medical treatment in US children with allergic disease.

METHODS:

The authors analyzed data from the 2007 to 2008 National Survey of Children’s Health, including a nationally representative sample of 27,556 children 0 to 5 years old.

RESULTS:

The prevalence (95% confidence interval [CI]) of at least 1 allergic disease was 29.4% (28.0-30.8); 6.6% (5.8-7.4) were diagnosed with asthma, 15.0% (14.0-16.0) with eczema, 11.6% (10.6-12.6) with hay fever, and 6.1% (5.4-6.9) with food allergy.

Children with allergic disorders had higher odds of at least 1 comorbid psychiatric and behavioral disorder (PBD; survey logistic regression; odds ratio 2.93, 95% CI 2.13-4.03),

including attention-deficit/hyperactivity disorder (4.75, 2.89-7.80),

depression (6.03, 1.29-28.27),

anxiety (5.54, 2.70-11.37),

conduct/oppositional defiant disorder (2.97, 1.88-4.70),

and learning delay (2.49, 1.70-3.66),

but not autism/Asperger disorder (1.89, 0.98-3.64).

The prevalence of injury in the past year requiring medical attention was 10.5% (95% CI 9.5-11.4). The association between allergic disease and injury requiring medical attention was mediated in part by a PBD (Sobel test 0.0021, 95% CI 0.0014-0.0029, P < .0001; bootstrapping approach, indirect effects, odds ratio 1.005, 95% CI 1.003-1.007; Baron-Kenny β(yx,m) = 0.04, P < .0001, R2 = 0.002). However, children with at least 1 allergic disorder (1.74, 1.23-2.46), including eczema (1.59, 1.01-2.50), asthma (1.91, 1.10-3.31), hay fever (2.05, 1.24-3.39), and food allergies (2.00, 1.10-3.67), had higher odds of sustaining injuries even after controlling for comorbid PBDs and medical disorders.

CONCLUSION:

The results suggest that the association between allergic disease and injury is multifactorial, including being secondary to PBD.
