If you’re a parent navigating the world of Autism Spectrum Disorder (ASD), you might have noticed that boys seem to be diagnosed with ASD more often than girls. You’re not alone in this observation. A recent international study has delved into why this might be the case, providing new insights that could help parents understand the differences in how ASD affects boys and girls.
The Study’s Approach
This comprehensive study was a collaborative effort involving researchers from the Chinese University of Hong Kong, the Icahn School of Medicine at Mount Sinai in the US, Karolinska Institutet in Sweden, and other institutions. They analysed data from over a million children born in Sweden between 1985 and 1998. By looking at the medical records of these children up to the age of 19, the researchers aimed to uncover how genetics might play a different role in ASD for boys and girls.

Key Findings
Out of the 1,047,619 children included in the study, 12,226 were diagnosed with ASD. Notably, 8,128 of these diagnoses were in boys, while 4,098 were in girls. This means that about 1.51 per cent of boys and 0.80 per cent of girls were diagnosed with ASD by age 19.
The study found that the genetic component, or heritability, of ASD was higher in boys (87.0 per cent) compared to girls (75.7 per cent). This suggests that genetics might be a more significant factor in ASD for boys than for girls.

What This Means for Parents
As a parent, understanding these findings can be crucial. The study indicates that boys might be more likely to inherit ASD due to their genetic makeup. However, for girls, other factors like environmental influences or unique genetic mutations might play a bigger role.
Professor Benjamin Hon-Kei Yip from CUHK explained that girls might be less impacted by inherited genetic factors or might be more vulnerable to other risks such as environmental factors or cultural differences in diagnosing ASD.

Impact on Future Research and Treatment
These findings highlight the importance of considering gender differences when researching and treating ASD. For parents, this means that future developments in ASD treatment could become more personalised, potentially offering different approaches for boys and girls based on their unique genetic profiles.
Expert Insights
Professor Sven Sandin from the Icahn School of Medicine at Mount Sinai emphasised the significance of this study. He noted that understanding the genetic differences between boys and girls with ASD could lead to breakthroughs in how we diagnose and treat the condition. This could mean more effective and tailored treatments for your child in the future.
Navigating ASD as a parent can be challenging, but understanding the factors that contribute to its development can make a big difference. This study sheds light on why boys are more frequently diagnosed with ASD than girls, pointing to genetic differences as a key factor. By recognising these differences, researchers and clinicians can develop better, more personalised strategies for supporting children with ASD.

Knowing that your child’s condition might be influenced by different factors based on their gender can help you seek out the most appropriate and effective care. As research continues to evolve, there’s hope for even more targeted and effective treatments for all children on the autism spectrum.
