Abstract
Aim
To describe the point prevalence of cerebral palsy (CP) and distribution of gross and fine motor function in individuals registered in a CP‐North surveillance programme.
Method
Aggregate data of individuals with CP aged 6 to 19 years, sex, CP subtype, and gross and fine motor function levels were collected from each programme. Overall and age‐specific point prevalence of CP was calculated for each programme using 95% confidence intervals. Logistic regression was used to estimate prevalence and CP subtypes with age as the covariate variable. Pearson χ2 tests were used to compare the distributions of CP subtypes, Gross Motor Function Classification System (GMFCS) levels, and Manual Ability Classification System (MACS) levels by age and between programmes.
Results
Among 3 759 138 individuals residing in Scandinavia and Scotland, 8278 had a diagnosis of CP (57–59% were males). The overall point prevalence of CP ranged from 2.13 to 2.32 per 1000 residents. Age‐specific prevalence in each programme varied with the exception of Denmark. While the proportions of bilateral spastic CP were similar between programmes, there were variations in all other CP subtypes and in GMFCS and MACS levels.
Interpretation
While the results of this study may reflect real differences in CP populations between countries, they may not be clinically relevant. The variations may be attributable to differences in the year when each programme was first established, different data collection methods, and country‐specific governmental policies.
