BACKGROUND
Foot posture which forms the distal supporting structure influences on postural stability. Children with developmental coordination disorder (DCD) who are more likely to be overweight or obese may present with flat foot with symptoms that affect daily activities. The aim of this study was to compare the foot posture and body composition measures between children with and without DCD. In addition, this study aimed to investigate the relationship between foot posture and fat percentage.
METHODS
Fifty-nine children with DCD (mean age = 8.07±1.10) and sixty-two typically developing children (mean age = 7.97±1.05) were recruited to the DCD and control group respectively. All children received a foot posture assessment and a whole-body dual-energy X-ray absorptiometry (DXA) scan. Foot Posture Index 6 (FPI-6) total scores, sub-scores and lower limb body composition measures including fat mass, lean mass, total mass, fat percentage and fat mass index were measured.
RESULTS
Children with DCD revealed a significantly higher FPI-6 left (1.12; 95% CI: 0.172, 2.061) and right (1.15; 95% CI: 0.218, 2.079) total score. FPI-6 sub-scores (talar head palpation and abduction/adduction forefoot on rearfoot) illustrated significant differences between children with and without DCD. Children with DCD had a significantly higher total fat mass (1247.48g; 95% CI: 121.654, 2373.304), total fat percentage (1.82%; 95% CI: 0.115, 3.525) and fat mass index (0.56kg/m2; 95% CI: 0.036, 1.069). There was a significant relationship between FPI-6 right total score and total fat percentage.
CONCLUSION
The findings of this study showed that children with DCD exhibited significantly more pronated foot posture and higher body composition measures compared to typically developing children. Moreover, with FPI-6 right total score significantly related to the total fat percentage, it may require more than just detecting abnormal foot structures in children with DCD but also promoting a healthy lifestyle to prevent obesity.
背景
形成远端支撑结构的足部姿势会影响姿势稳定性。患有发育性协调障碍（DCD）的儿童更有可能超重或肥胖，他们可能会出现扁平足，并出现影响日常活动的症状。本研究的目的是比较 DCD 儿童和无 DCD 儿童的足部姿势和身体成分测量值。此外，本研究旨在探讨足部姿势与脂肪百分比之间的关系。
方法
分别招募 59 名 DCD 儿童（平均年龄=8.07±1.10）和 62 名发育正常的儿童（平均年龄=7.97±1.05）进入 DCD 组和对照组。所有儿童均接受足部姿势评估和全身双能 X 线吸收法（DXA）扫描。测量足部姿势指数 6（FPI-6）总分、子分数和下肢身体成分测量值，包括脂肪量、瘦体重、总质量、脂肪百分比和脂肪质量指数。
结果
DCD 儿童的 FPI-6 左侧（1.12；95%置信区间：0.172，2.061）和右侧（1.15；95%置信区间：0.218，2.079）总分明显较高。FPI-6 子分数（距骨头部触诊和后足前足外展/内收）显示 DCD 儿童与无 DCD 儿童之间存在显著差异。DCD 儿童的总脂肪量（1247.48g；95%置信区间：121.654，2373.304）、总脂肪百分比（1.82%；95%置信区间：0.115，3.525）和脂肪质量指数（0.56kg/m2；95%置信区间：0.036，1.069）均显著较高。FPI-6 右侧总分与总脂肪百分比之间存在显著关系。
结论
本研究结果表明，与发育正常的儿童相比，DCD 儿童的足部姿势明显更加内翻，身体成分测量值也更高。此外，FPI-6 右侧总分与总脂肪百分比显著相关，这可能意味着不仅需要检测 DCD 儿童的异常足部结构，还需要促进健康的生活方式以预防肥胖。
