目的评价一学年学校体育活动方案对小学生身心健康的影响。设计聚类随机对照试验。从2005年8月至2006年6月，在瑞士15所小学中随机抽取28个班级，按4:3的比例按年级（一年级和五年级）分层后，将其分配到干预组（n=16）或对照组（n=12）。参与者540名儿童，其中502人同意并在基线时提出。干预组的儿童（n=297）接受了一个多部分的体育活动计划，包括每周安排三节现有的体育课程，每周增加两节额外的课程，每天短暂的活动休息，以及体育活动作业。对照组的儿童（n=205）和家长未被告知干预组。对于大多数结果测量，评估者是盲法的。主要结局指标主要结局指标包括体脂（四个皮褶的总和）、有氧适能（穿梭跑测试）、身体活动（加速度计）和生活质量（问卷调查）。次要结局指标包括体重指数和心血管风险评分（腰围平均z分、平均血压、血糖、倒置高密度脂蛋白胆固醇和甘油三酯）。结果498名儿童完成了基线和随访评估（一年级平均年龄6.9岁（SD 0.3），五年级平均年龄11.1岁（0.5））。在对年级、性别、基线值和班级内聚类进行调整后，与对照组相比，干预组的儿童在四个皮肤褶皱总和的z得分上表现出更多的负变化（- 0.12,95%可信区间- 0.21至- 0.03；P=0.009）。同样，他们在有氧健身方面的z分数增加得更有利（0.17,0.01至0.32，P=0.04），在学校进行中等强度体育活动（1.19,0.78至1.60，P<0.001），整天进行中等强度体育活动（0.44,0.05至0.82，P=0.03），以及在学校的总体育活动（0.92,0.35至1.50，P=0.003）。总体每日体力活动（0.21,- 0.21至0.63）、身体生活质量（0.42,- 1.23至2.06）以及心理生活质量（0.59,- 0.85至2.03）的Z得分没有显著变化。结论以学校为基础的包括强制性要素的多组分体育活动干预可改善儿童的体育活动和健康，减少肥胖。当前对照试验ISRCTN15360785。
Objective To assess the effectiveness of a school based physical activity programme during one school year on physical and psychological health in young schoolchildren. Design Cluster randomised controlled trial. Setting 28 classes from 15 elementary schools in Switzerland randomly selected and assigned in a 4:3 ratio to an intervention (n=16) or control arm (n=12) after stratification for grade (first and fifth grade), from August 2005 to June 2006. Participants 540 children, of whom 502 consented and presented at baseline. Intervention Children in the intervention arm (n=297) received a multi-component physical activity programme that included structuring the three existing physical education lessons each week and adding two additional lessons a week, daily short activity breaks, and physical activity homework. Children (n=205) and parents in the control group were not informed of an intervention group. For most outcome measures, the assessors were blinded. Main outcome measures Primary outcome measures included body fat (sum of four skinfolds), aerobic fitness (shuttle run test), physical activity (accelerometry), and quality of life (questionnaires). Secondary outcome measures included body mass index and cardiovascular risk score (average z score of waist circumference, mean blood pressure, blood glucose, inverted high density lipoprotein cholesterol, and triglycerides). Results 498 children completed the baseline and follow-up assessments (mean age 6.9 (SD 0.3) years for first grade, 11.1 (0.5) years for fifth grade). After adjustment for grade, sex, baseline values, and clustering within classes, children in the intervention arm compared with controls showed more negative changes in the z score of the sum of four skinfolds (−0.12, 95 % confidence interval −0.21 to −0.03; P=0.009). Likewise, their z scores for aerobic fitness increased more favourably (0.17, 0.01 to 0.32; P=0.04), as did those for moderate-vigorous physical activity in school (1.19, 0.78 to 1.60; P<0.001), all day moderate-vigorous physical activity (0.44, 0.05 to 0.82; P=0.03), and total physical activity in school (0.92, 0.35 to 1.50; P=0.003). Z scores for overall daily physical activity (0.21, −0.21 to 0.63) and physical quality of life (0.42, −1.23 to 2.06) as well as psychological quality of life (0.59, −0.85 to 2.03) did not change significantly. Conclusions A school based multi-component physical activity intervention including compulsory elements improved physical activity and fitness and reduced adiposity in children. Trial registration Current Controlled Trials ISRCTN15360785.
