Is parent education a factor in identifying autism/takiwātanga in an ethnic cohort of Pacific children in Aotearoa, New Zealand? A national cross-sectional study using linked administrative data.

The method used to identify autism cases relies on health service interactions and has not been validated, meaning it may miss children who never accessed services or who were not diagnosed despite having autism. The study only included Pacific children; Māori children were excluded unless they also identified as Pacific, so findings do not apply to Māori populations. Parental education was estimated from census data rather than directly measured, which may introduce some inaccuracy. The study design cannot prove causation; it is unclear whether higher education leads to more diagnoses due to better navigation of the system, or if other unmeasured factors are responsible.

The authors declared no potential conflicts of interest. Funding was provided by the Health Research Council of New Zealand and the A Better Start National Science Challenge (funded by the New Zealand Ministry of Business, Innovation and Employment).

Do not interpret the link between higher parental education and autism diagnosis as evidence that less educated parents have children who are less autistic. The study suggests that higher education helps parents navigate the health system to get a diagnosis, meaning the lower diagnosis rate in less educated groups likely reflects inequitable access to services rather than a true difference in prevalence.
