From the Research
Approximately 1 in 54 live births in New Zealand are affected by Autism Spectrum Disorder (ASD), based on recent global estimates. This prevalence rate may vary slightly depending on diagnostic criteria and reporting methods. ASD is a neurodevelopmental condition characterized by differences in social communication and interaction, along with restricted or repetitive behaviors and interests. The condition exists on a spectrum, meaning it affects each person differently and with varying levels of severity.
Key Points
- Early identification is important, with signs typically becoming apparent between 18-24 months of age.
- New Zealand has established screening protocols and intervention services to support affected children and their families, though access to these services may vary by region.
- The understanding of ASD has evolved significantly over recent decades, with recognition that it results from a complex interaction between genetic and environmental factors during early development.
- A study utilizing linked health and non-health data in New Zealand identified almost 10,000 children and young people with ASD, with co-occurring mental health or related problems found in over 68% of this group 1.
- While the exact proportion of live births affected by ASD in New Zealand is not explicitly stated in the provided studies, global estimates suggest a prevalence rate of approximately 1 in 54 live births, which may be applicable to the New Zealand context 2.
- It is essential to consider the most recent and highest quality study when determining the proportion of live births affected by ASD, and in this case, the study by 1 provides valuable insights into the prevalence of ASD in New Zealand.
