Comprehensively and objectively assess physical activity, aerobic fitness and body fat in adolescents and young adults with myelomeningocele and to investigate their relationships.
Cross-sectional study.
Fifty-one persons (26 males) with myelomeningocele aged 21.1 (standard deviation) 4.5) years.
Physical activity was measured with an accelerometry-based activity monitor. Aerobic fitness was defined as the maximum oxygen uptake during the last minute of a maximal exercise test. Body fat was assessed using sum of 4 skin-folds and body mass index. Correlations were studied using multiple regression analyses.
Thirty-nine percent of the participants were inactive and another 37% were extremely inactive. Aerobic fitness was 42% lower than normative values and 35% were obese. Ambulatory status was related to daily physical activity (beta = 0.541), aerobic fitness (beta = 0.397) and body fat (beta = -0.243). Gender was related to aerobic fitness (beta = -0.529) and body fat (beta = 0.610). Physical activity was related to aerobic fitness in non-ambulatory persons with myelomeningocele (beta = 0.398), but not in ambulatory persons.
Adolescents and young adults with myelomeningocele were physically inactive, had poor aerobic fitness and high body fat. Differences exist between subgroups regarding gender and ambulatory status.
全面、客观地评估患有脊髓脊膜膨出的青少年和青年的身体活动、有氧适能和体脂情况，并研究它们之间的关系。
横断面研究。
51名年龄为21.1（标准差4.5）岁的患有脊髓脊膜膨出的患者（26名男性）。
使用基于加速度计的活动监测器测量身体活动。有氧适能定义为最大运动测试最后一分钟的最大摄氧量。使用4个皮褶厚度之和和体重指数评估体脂。采用多元回归分析研究相关性。
39%的参与者身体活动不足，另外37%极度缺乏身体活动。有氧适能比正常水平低42%，35%的人肥胖。行走状态与日常身体活动（β=0.541）、有氧适能（β=0.397）和体脂（β=-0.243）有关。性别与有氧适能（β=-0.529）和体脂（β=0.610）有关。身体活动与非行走型脊髓脊膜膨出患者的有氧适能有关（β=0.398），但与行走型患者无关。
患有脊髓脊膜膨出的青少年和青年身体活动不足，有氧适能差，体脂高。在性别和行走状态的亚组之间存在差异。
