Insights
Children with early childhood allergic rhinitis and wheezing face higher risks of internalizing disorders like anxiety and depression by age seven. Multiple allergic conditions amplify this risk in a dose-dependent manner.
Area of Science:
- Pediatric Allergy and Immunology
- Child and Adolescent Psychiatry
- Developmental Psychology
Background:
- The link between allergic diseases and internalizing disorders requires further investigation, especially concerning multiple conditions and longitudinal data.
- Previous studies have not fully characterized the long-term association between early-life allergic diseases and later internalizing behaviors.
Purpose of the Study:
- To investigate the association between multiple allergic diseases in early childhood and validated measures of internalizing disorders in school-aged children.
- To examine the dose-dependent relationship between the number of allergic diseases and internalizing behaviors.
Main Methods:
- Longitudinal study of 546 children from the Cincinnati Childhood Allergy and Air Pollution Study.
- Assessment of allergic diseases (allergic rhinitis, persistent wheezing, atopic dermatitis, sensitization) at age 4.
- Evaluation of internalizing disorders using the Behavior Assessment System for Children, Second Edition (BASC-2) at age 7, analyzed via logistic and linear regression.
Main Results:
- Allergic rhinitis at age 4 was significantly linked to higher internalizing, anxiety, and depression scores at age 7.
- Allergic persistent wheezing at age 4 was associated with elevated internalizing scores.
- The presence of multiple allergic diseases at age 4 showed a dose-dependent association with increased internalizing scores.
Conclusions:
- Early childhood allergic rhinitis and persistent wheezing increase the risk for internalizing behaviors in school-aged children.
- A greater number of allergic diseases in early childhood is associated with a higher risk and severity of internalizing disorders.
Background And Objectives:
The relationship between allergic diseases and internalizing disorders has not been well characterized with regard to multiple allergic diseases or longitudinal study. The objective of this study was to examine the association between multiple allergic diseases in early childhood with validated measures of internalizing disorders in the school-age years.
Methods:
Children enrolled in the Cincinnati Childhood Allergy and Air Pollution Study underwent skin testing and examinations at ages 1, 2, 3, 4, and 7 years. At age 7, parents completed the Behavior Assessment System for Children, Second Edition (BASC-2), a validated measure of childhood behavior and emotion. The association between allergic diseases at age 4, including allergic rhinitis, allergic persistent wheezing, atopic dermatitis, and allergic sensitization, and BASC-2 internalizing, anxiety, and depression T scores at age 7 was examined by logistic and linear regression, adjusting for covariates.
Results:
The cohort included 546 children with complete information on allergic disease and BASC-2 outcomes. Allergic rhinitis at age 4 was significantly associated with elevated internalizing (adjusted odds ratio [aOR]: 3.2; 95% confidence interval [CI]: 1.8-5.8), anxiety (aOR: 2.0; 95% CI: 1.2-3.6), and depressive scores (aOR: 3.2; 95% CI: 1.7-6.5) at age 7. Allergic persistent wheezing was significantly associated with elevated internalizing scores (aOR: 2.7; 95% CI: 1.2-6.3). The presence of >1 allergic disease (aOR: 3.6; 95% CI: 1.7-7.6) and allergic rhinitis with comorbid allergic disease(s) (aOR: 4.3; 95% CI: 2.0-9.2) at age 4 had dose-dependent associations with internalizing scores.
Conclusions:
Children with allergic rhinitis and allergic persistent wheezing at age 4 are at increased risk of internalizing behaviors at age 7. Furthermore, multiple allergic diseases had a dose-dependent association with elevated internalizing scores.
