本研究的目的是：1)测量儿童和青少年CF患者和非CF健康对照儿童青少年的总体力活动水平，包括各种活动的强度；2)确定CFF患者剧烈运动水平是否与有氧能力和疾病状况有关。方法选择CF30例(男18例，女12例)和对照组30例(男17例，女13例)，年龄7~17岁。使用Kriska的可修改活动问卷(MAQ)测量了习惯性体力活动，并确定了过去一年的每周活动总时数、满足时数和剧烈活动时数(>；6 Met)的平均值。有氧适能是通过自行车测功器上的最大运动试验获得的最大摄氧量(VO2峰值)来确定的。采用标准肺活量测定法测定肺功能。结果两组患者的年龄和性别分布相似，但患者的BMI较小(BMI，98vs112%)，有氧适应能力较差(36.5mLxkg(-1)xmin(-1))。两组间的体力活动总时数和满足时数没有差异；然而，CF组参加剧烈运动的时数明显少于对照组(2vs3.7hxwk(-1))。在肺部疾病较严重的患者中，VIG-h×wk(-1)与VO2峰值显著相关(r=0.83)。结论尽管肺功能良好，但慢性肺病儿童的剧烈体力活动比健康的非慢性肺病儿童要少。鉴于疾病的进行性，以及有氧健身和剧烈运动之间的联系，应鼓励患者从事更剧烈的运动，以促进有氧健身，并最终可能对生存产生影响。
PurposeThis study was conducted to: 1) measure total physical activity levels, including the intensities of the various types of activities, in children and adolescents with CF compared with non-CF healthy control subjects; and 2) determine whether vigorous activity level was related to aerobic fitness and disease status in patients with CF.MethodsThirty patients with CF (18 male, 12 female) and 30 control subjects (17 male, 13 female), 7-17 yr old, participated in this study. Habitual physical activity was measured using Kriska's Modifiable Activity Questionnaire (MAQ) and the past year's average of total hours, MET-hours, and vigorous (VIG) hours (> 6 METs) of activity per week were determined. Aerobic fitness was determined from peak oxygen uptake (VO2peak) obtained via maximal exercise testing on a cycle ergometer. Standard spirometry was used to measure pulmonary function. Body mass index (BMI) was determined from height and weight measurements.ResultsThe CF and control groups were similar in age and gender distribution, but the patients were smaller (BMI, 98 vs 112% of predicted) and less aerobically fit (36.5 vs 41.4 mL x kg (-1) x min (-1)). Total and MET-hours of physical activity did not differ between groups; however, the CF group participated in significantly fewer hours of vigorous activities than the control group (2 vs 3.7 hx wk (-1)). In patients with worse lung disease, VIG-h x wk (-1) were significantly related to VO2peak (r= 0.83).ConclusionThese results suggest that children with CF engage in less vigorous physical activities than their healthy non-CF peers, despite having good lung function. In view of the progressive nature of the disease, and the association between aerobic fitness and vigorous activity, patients should be encouraged to engage in more vigorous activities that promote aerobic fitness and may ultimately have an impact on survival.
