Physical inactivity in youth with cerebral palsy (CP) places them at increased risk of developing cardiovascular disease. The current study assessed indices of arterial health in adolescents with CP, classified as levels I-II of the Gross Motor Function Classification System (GMFCS) (n = 11, age 13.2 ± 2.1 yr), in comparison to age- and sex-matched controls (n = 11, age 12.4 ± 2.3 yr). Groups were similar in anthropometric measurements, resting blood pressures, and heart rates. There were no group differences in brachial flow-mediated dilation (11.1 ± 7.8 versus 6.1 ± 3.6), carotid intima-media thickness (0.42 ± 0.04 versus 0.41 ± 0.03 mm), and distensibility (0.008 ± 0.002 versus 0.008 ± 0.002 mmHg) or central (4.3 ± 0.6 versus 4.1 ± 0.9 m/s) and peripheral pulse wave velocity (7.1 ± 1.7 versus 7.6 ± 1.1 m/s); CP versus healthy controls, respectively. Vigorous intensity physical activity (PA) was lower in the CP group (CP: 38 ± 80 min versus controls: 196 ± 174 min); groups were similar in light and moderate intensity PA levels. Arterial health of ambulatory youth with CP is not different from a control group despite lower vigorous PA levels. Similar studies need to examine individuals with more pronounced mobility limitations (GMFCS level III-V).
患有脑瘫(CP)的青少年缺乏身体活动会增加他们患心血管疾病的风险。本研究评估了按粗大运动功能分类系统(GMFCS)I-II级分类的脑瘫青少年(n = 11,年龄13.2±2.1岁)的动脉健康指标,并与年龄和性别匹配的对照组(n = 11,年龄12.4±2.3岁)进行比较。两组在人体测量、静息血压和心率方面相似。肱动脉血流介导的扩张(11.1±7.8对6.1±3.6)、颈动脉内膜中层厚度(0.42±0.04对0.41±0.03毫米)、扩张性(0.008±0.002对0.008±0.002毫米汞柱)或中心(4.3±0.6对4.1±0.9米/秒)和外周脉搏波速度(7.1±1.7对7.6±1.1米/秒)方面无组间差异;分别为脑瘫组与健康对照组。脑瘫组的剧烈强度身体活动(PA)较低(脑瘫组:38±80分钟对对照组:196±174分钟);两组在轻度和中度强度PA水平方面相似。尽管剧烈PA水平较低,但能行走的脑瘫青少年的动脉健康与对照组并无差异。类似的研究需要对行动受限更明显的个体(GMFCS III-V级)进行检查。
