OBJECTIVE
This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination.
METHODS
This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%). Weight, height, and waist circumference were objectively measured by standardized protocols. Body fat percentage was estimated by bioelectric impedance. Body mass index and waist-to-height ratio were computed. Motor coordination was assessed by the Körperkoordination Test für Kinder. Cardiorespiratory fitness was predicted by a maximal multistage 20 m shuttle-run test of the Fitnessgram Test Battery. A questionnaire was used to assess the maternal educational level.
RESULTS
The receiver operating characteristic performance of body fat percentage in females and waist circumference in males presented a slightly better discriminatory accuracy than body mass index, waist circumference and waist-to-height ratio in predicting low motor coordination. After adjustments, logistic regression analyses showed that body mass index (β=2.155; 95% CI: 1.164-3.992; p=0.015 for girls; β=3.255; 95% CI: 1.740-6.088; p<0.001 for males), waist circumference (β=2.489; 95% CI: 1.242-4.988; p=0.010 for girls; β=3.296; 95% CI: 1.784-6.090; p<0.001 for males), body fat percentage (β=2.395; 95% CI: 1.234-4.646; p=0.010 for girls; β=2.603; 95% CI: 1.462-4.634; p<0.001 for males) and waist-to-height ratio (β=3.840; 95% CI: 2.025-7.283; p<0.001 for males) were positively and significantly associated with motor coordination in both sexes, with the exception of waist-to-height ratio in girls (β=1.343; 95% CI: 0.713-2.528; p=0.381).
CONCLUSION
Body fat percentage and waist circumference showed a slightly better discriminatory accuracy in predicting low motor coordination for females and for males, respectively.
目的
本研究旨在确定不同肥胖指标区分低/高运动协调性的能力，并评估不同肥胖指标与运动协调性之间的关系。
方法
本研究纳入了596名9至12岁的小学生（218名女性，占47.1%）。通过标准化方案客观测量体重、身高和腰围。通过生物电阻抗法估算体脂百分比。计算体重指数和腰高比。通过儿童运动协调性测试评估运动协调性。通过Fitnessgram测试电池组的最大多级20米往返跑测试预测心肺适能。使用问卷评估母亲的教育水平。
结果
在预测低运动协调性方面，女性的体脂百分比和男性的腰围的受试者工作特征表现出比体重指数、腰围和腰高比略好的辨别准确性。调整后，逻辑回归分析显示，体重指数（女孩β=2.155；95%置信区间：1.164 - 3.992；p = 0.015；男孩β=3.255；95%置信区间：1.740 - 6.088；p < 0.001）、腰围（女孩β=2.489；95%置信区间：1.242 - 4.988；p = 0.010；男孩β=3.296；95%置信区间：1.784 - 6.090；p < 0.001）、体脂百分比（女孩β=2.395；95%置信区间：1.234 - 4.646；p = 0.010；男孩β=2.603；95%置信区间：1.462 - 4.634；p < 0.001）和腰高比（男孩β=3.840；95%置信区间：2.025 - 7.283；p < 0.001）与两性的运动协调性均呈正相关且具有显著性，女孩的腰高比除外（β=1.343；95%置信区间：0.713 - 2.528；p = 0.381）。
结论
体脂百分比和腰围在分别预测女性和男性的低运动协调性方面表现出略好的辨别准确性。
