To describe post-neonatally acquired (PNN) cerebral palsy (CP) in terms of temporal trends in prevalence, clinical and sociodemographic profiles, known causes and associations between causes, and sociodemographic variables.Numerator data, a count of children with PNN-CP confirmed at 5 years of age (n = 523), was drawn from two Australian state CP registers (birth years 1973-2012). Poisson regression was used to investigate temporal trends in the prevalence of PNN-CP by 5-year intervals, calculated per 10 000 live births. Using data from all state and territory Australian CP registers (n = 469), distributions of clinical characteristics, PNN-CP causes, and sociodemographic factors were tabulated (birth years 1995-2012). χA significant temporal decline in PNN-CP in Victoria (p = 0.047) and Western Australia (p = 0.033) was observed. The most common proximal causes of PNN-CP were cerebrovascular accidents (34%, n = 158), infection (25%, n = 117), and non-accidental injuries (12%, n = 58). Children born to teenage mothers, Aboriginal and/or Torres Strait Islander mothers, or children born in remote areas were over-represented in this cohort compared with reference data (all p ≤ 0.001). Infectious causes were strongly associated with teenage motherhood (odds ratio 3.0 [95% confidence interval 1.1-8.2], p = 0.028) and remote living (odds ratio 4.5 [95% confidence interval 2.0-10.2], p 0.001).Although prevalence of PNN-CP has declined, the over-representation of priority populations, and the relative severity of a condition that is largely preventable, suggest the need for more specific primary preventive measures and support.Prevalence of post-neonatally acquired (PNN) cerebral palsy (CP) in Australia significantly declined between 1973 and 2012. Cerebrovascular accidents are the most common proximal cause of PNN-CP. Children born in remote areas are at greater risk of PNN-CP.
