ObjectivesTo assess differences in body composition according to gross motor function in children with cerebral palsy (CP) compared to healthy controls.DesignRetrospective case control study.Setting: Tertiary referral center for CPParticipantsOne hundred consecutive patients (mean age, 11.5 ± 4.2 years) with CP who were admitted for orthopedic surgery between May 2014 and March 2016 and 46 typically developing children (TDC, control group) were included.InterventionNot applicableMain Outcome MeasuresBioelectrical impedance analysis (BIA) was used to assess body composition, including body fat, soft lean mass (SLM), fat free mass (FFM), skeletal muscle mass (SMM), body cell mass (BMC), bone mineral content (BMC), and basal metabolic rate (BMR). Body composition measures were compared according to gross motor function classification system (GMFCS) level, as well as between children with CP and TDC.ResultsChildren with CP with GMFCS levels IV and V had a lower height, weight, and body mass index than those with GMFCS levels I, II, and III. Children with CP with GMFCS levels IV and V had a significantly lower SLM, SLM index, FFM, FFM index, SMM, SMM index, BCM, BCM index, BMC, and BMC index than those with GMFCS levels I to III and TDC. GMFCS level significantly affected SLM and BMC.ConclusionsBody composition analysis using BIA showed that non-ambulatory children with CP had significantly lower FFM, SLM, SMM, BCM, and BMC than ambulatory children with CP and TDC. However, further study is required to allow the use of BIA as a valid nutritional assessment tool in patients with CP.
