Abstract
OBJECTIVE: To describe the relationship between activity level and cardiovascular risk measures as well as describe general activity patterns of adults with cerebral palsy. DESIGN: Cross-sectional. SETTING: Academic outpatient rehabilitation clinic. PARTICIPANTS: Adults with cerebral palsy (N=47). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Gross Motor Functional Classification System (GMFCS) level was determined by validated self-report questionnaire. Activity (daily step count, walk time, sitting time, standing time, and transitional movements) over 6 days recorded using an activPAL. Weight, body mass index (BMI), and waist-to-hip ratio were measured. Bivariate relationships between anthropomorphic and activity measures were assessed. RESULTS: Thirty-eight participants completed all measurements. Nine were excluded because of incomplete activPAL data. The median age was 28.50 years (interquartile range [IQR]=24.25-47.00), range 18-77 years. Participants' GMFCS levels were I: 13%; II: 16%; III: 21%; IV: 34%; and V: 16%. Median steps/day for GMFCS I/II participants were 5258.3 (IQR=3606.8-6634.7), and median steps/day were 1681.3 (IQR=657.2-2751.8) and 30.0 (IQR=6.8-54.2) for GMFCS level III and IV/V participants, respectively. Significantly greater steps/day were found for GMFCS I/II or III participants compared to those GMFCS IV/V (P<.001 and p=".0074," respectively). in addition, 60.5% of the subjects had a bmi in the normal range, 10.5% were obese, 23.6% were overweight, and 5.3% were underweight. for subjects with gmfcs i ii, the spearman's rank correlation coefficient for time standing and waist circumference was -0.73 (0.01). gmfcs iii and gmfcs iv v participants had respective correlations of -0.16 (0.71) and -0.01 (0.98). for subjects with gmfcs i ii, the spearman's rank correlation coefficient for standing time and bmi was -0.55 (p=".08)." for the gmfcs iii and gmfcs iv v groups the respective correlations were -0.19 (0.67) and 0.00 (1.00). conclusions: subjects with gmfcs level i or ii who engaged in more activity tended to have more favorable anthropometric profiles. subjects with gmfcs level iii, iv, or v did not have a similar trend. our findings suggest factors beyond activity patterns affect anthropometrics to a greater degree in those with higher gmfcs levels. elsevier inc. all rights reserved.>
