Insights
Familial allergic or autoimmune diseases are linked to autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in children. This familial aggregation, particularly from mothers, highlights the need for early ASD and ADHD assessments in at-risk children.
Area of Science:
- Pediatric Health
- Neurodevelopmental Disorders
- Immunology
Background:
- Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) frequently co-occur with allergic and autoimmune conditions in children.
- Understanding the familial links between these conditions is crucial for early identification and intervention.
Purpose of the Study:
- To investigate the association between allergic/autoimmune diseases in children and their first-degree relatives (parents, siblings) and the children's risk of ASD and/or ADHD.
- To explore the impact of familial aggregation of these diseases on the development of ASD/ADHD.
Main Methods:
- Utilized Taiwan's Maternal and Child Health Database for a large-scale cohort study.
- Employed Cox regression models to analyze associations between familial, sibling, and child diagnoses of allergic/autoimmune diseases and ASD/ADHD.
- Included 1,386,260 children in the analysis.
Main Results:
- A significant association was found between familial allergic or autoimmune disease and the development of ASD or ADHD in children.
- Familial aggregation of allergic and autoimmune diseases showed a predominant impact on these associations.
- Maternal diagnoses of allergic or autoimmune diseases showed stronger associations with children's ASD/ADHD compared to paternal diagnoses.
Conclusions:
- Children with a family history of allergic or autoimmune diseases have an increased risk for ASD and/or ADHD.
- Early screening for ASD and ADHD is recommended for children with a parental history of allergic or autoimmune conditions.
- The findings underscore the importance of considering genetic and environmental factors in the etiology of neurodevelopmental disorders.
Abstract:
Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are commonly comorbid with allergic and autoimmune diseases in children. The aim of the current study was to investigate the association between children's and first-degree relatives' (i.e., mother, father, and full sibling) allergic and autoimmune diseases and children's ASD and ADHD. We enrolled participants from Taiwan's Maternal and Child Health Database. We used the Cox regression model to examine the associations of familial, siblings' and children's allergic and autoimmune diseases with children's ASD and/or ADHD. In total, we included 1,386,260 children in the current study. We found the significant association between familial allergic or autoimmune disease and development of ASD or ADHD among children. We also identified the predominant impact of familial aggregation on the above associations. The associations between some parental diagnoses of autoimmune or allergic diseases in children's ASD and/or ADHD were stronger in mothers than those in fathers. Early assessment of the possibility of ASD and ADHD is required for children who have a parent with an allergic or autoimmune disease.
