Clinical Correlates of Linear Growth in Children with Cerebral Palsy

The purpose of this cross-sectional study was to determine correlates of linear growth in children with cerebral palsy (CP). 171 children with CP were measured and their charts reviewed. z scores were calculated for weight (Wz) and height (Hz). Hz correlated positively with Wz and head circumference, and negatively with age, the presence of spastic quadriplegia, non-ambulation and seizures. The correlation between Hz and age was stronger when non-ambulatory children were analysed separately. Multiple linear regression resulted in only Wz and age contributing significantly to the variance in stature as measured by Hz. These results provide preliminary evidence that nutritional status is a major correlate of growth in CP. The finding that linear growth worsens with age independent of nutrition suggests that other factors also influence growth in CP.
