Insights
Children with allergic diseases show higher rates of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Respiratory allergies present a greater risk for ADHD compared to skin allergies. Increased awareness of these co-occurrences is recommended.
Area of Science:
- Pediatrics
- Neuroscience
- Allergy and Immunology
Background:
- Rising prevalence of neurodevelopmental disorders (NDs) and allergic diseases (ADs) in children.
- Need to understand the potential association between NDs and ADs.
- Focus on primary healthcare settings in Izmir.
Purpose of the Study:
- To analyze the association between neurodevelopmental disorders (ADHD, ASD) and allergic diseases (respiratory, skin) in children.
- To identify risk factors for these comorbidities.
Main Methods:
- Retrospective cross-sectional study of 20,557 children in Izmir primary healthcare units.
- Dependent variables: ADHD and ASD. Risk factors: respiratory and skin allergies.
- Logistic regression models adjusted for age, sex, and socioeconomic level.
Main Results:
- ADHD comorbidity was significantly higher in children with both respiratory (6.8%) and skin allergies (7.8%).
- Respiratory allergies showed a higher odds ratio (OR: 6.2) for ADHD than skin allergies (OR: 2.2).
- ASD comorbidity was observed in boys with respiratory (1.8%) and skin allergies (1.6%), but analysis for girls was limited.
Conclusions:
- Significant association found between allergic diseases and neurodevelopmental disorders, particularly ADHD.
- Healthcare providers and parents should be aware of the co-occurrence of NDs and ADs.
- Further research may be needed to explore these links.
Background And Objective:
The prevalence of neurodevelopmental disorders (NDs) and allergic diseases(ADs) has increased in recent years. This study aimed to analyse the association between them among children registered at primary healthcare units in Izmir.
Methods:
For this retrospective cross-sectional study, primary healthcare units in Izmir were selected by randomisation conducted between January 1, 2023 and December 31, 2023. The dependent variables are attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). The risk factors are respiratory allergies and skin allergies. Logistic regression models were adjusted for age, sex, socioeconomic level.
Results:
There were 20,557 children registered in 26 primary healthcare units. Skin allergy was detected in 7.8%, respiratory allergy in 6.8%, ADHD in 1.2% and ASD in 0.0%. ADHD comorbidity was found to be high in both children with respiratory allergies and children with skin allergies (p<0.001). The rate of ASD comorbidity was 1.8% in boys with respiratory allergies and 1.6% in boys with skin allergies (p>0.01). The analysis could not be performed due to the low number of girls with ASD. The logistic regression models showed a higher odds ratio for respiratory allergies (OR:6.2, 95% CI: 4.6-8.3) than for skin allergies (OR:2.2, 95% CI: 1.5-3.2) for ADHD.
Conclusion:
It would be beneficial to increase awareness among healthcare providers and parents about the co-occurrence of NDs and ADs.
