Growth failure and nutritional status were evaluated in 142 children with quadriplegic cerebral palsy, aged between two and 18 years. Linear growth was assessed by upper-arm and lower-leg lengths: both means were significantly reduced. Mean bodyweight and triceps skinfold thickness fat stores were reduced to 65 per cent medians and subcapsular skinfold fat stores to 81 per cent median. Muscle stores were the most preserved and reduced to 88 per cent median. Examination of the sample by age-group showed significant reductions in growth and nutrition status indicators, even at two to four years, except for muscle area. To determine the degree to which nutritional status affected linear growth, a set of two-step regression analyses was conducted. The linear growth measures were significantly correlated with the measures of nutritional status.
