背景：儿童超重(OW)和肥胖(OB)与运动技能和协调性的关系正受到应有的重视；目的：本研究的双重目的是：(1)根据儿童的体重状况，研究儿童粗大运动协调水平的短期演变；(2)找出预测两年后儿童粗大运动协调能力的因素。2007年(基线)和两年后的2009年(随访)分别评估了体脂百分比)和粗大运动协调性水平(Korperkocoorationstest ur Kinder，KTK)。在基线时，参与者完成了一项基于佛兰德体力活动问卷(FPAQ)的调查，以获得社会人口学信息并确定不同领域的体力活动水平。结果：粗大运动协调水平随时间的变化与儿童的体重状况密切相关。NW组的参与者比OW/OB组的参与者进步更多，后者的表现明显较差。因此，随着时间的推移，KTK结果(即原始条目分数和总运动商)的组间差异变得更加明显。多元线性回归分析进一步表明，除了体重指数本身(负预测因素)外，参加体育俱乐部内有组织的运动(正预测因素)还决定了两年后的粗大运动协调能力(S)。结论：我们的结果提供了确凿的证据，证明在缺乏针对性举措的情况下，OW/OB儿童在发育阶段相对于NW同龄人的大运动协调能力差距越来越大。因此，对于OW/OB儿童，特别是那些没有在俱乐部环境中练习运动的儿童，在运动技能提高方面需要特别关注，以促进定期参与体育活动。《国际肥胖杂志》(2013年)37期，61-67期；doi：10.1038/ijo.2012.55；2012年4月17日在线发表
BACKGROUND: The relationship of childhood overweight (OW) and obesity (OB) with motor skill and coordination is gaining due attention; however, longitudinal evidence is currently lacking.OBJECTIVE: The dual purpose of this study was (1) to investigate the short-term evolution in the level of gross motor coordination according to children's weight status, and (2) to identify those factors predicting their gross motor coordination performance over a 2-year interval.SUBJECTS: Participants were 50 children with OW, including 8 with OB (aged 6-10 years at baseline, with 52% boys), and 50 with normal-weight (NW) matched for gender and age.MEASUREMENTS: Anthropometrics (body height, body weight, body mass index (BMI), % body fat) and level of gross motor coordination (Korperkoordinationstest fur Kinder, KTK) were assessed in 2007 (baseline) and 2 years later in 2009 (follow-up). At baseline, participants completed a survey based on the Flemish Physical Activity Questionnaire (FPAQ) to obtain socio-demographic information and to determine physical activity levels in diverse domains.RESULTS: The evolution in the level of gross motor coordination over time was strongly related to children's weight status. Participants in the NW group showed more progress than their OW/OB peers, who demonstrated significantly poorer performances. Accordingly, between-group differences in KTK outcomes (that is, raw item scores and total motor quotient) became more evident over time. Multiple linear regression analysis further indicated that, in addition to BMI per se (negative predictor), participation in organized sports within a sports club (positive predictor) determines gross motor coordination performance(s) 2 years later.CONCLUSION: Our results provide conclusive evidence for an increasingly widening gap of OW/OB children's gross motor coordination relative to NW peers across developmental time in the absence of targeted initiatives. Special attention is thus needed for OW/OB children, especially for those not practicing sports in a club environment, in terms of motor skill improvement to promote regular participation in physical activity.
