發展協調障礙兒童之心血管危險因子特性分析

背景與目的：迄今國際上甚少使用探討發展協調障礙兒童心血管危險因子之研究，過去研究雖指出發展協調障礙兒童之體適能與心肺功能明顯低於正常發展兒童，而且這可能導致成年得心血管疾病的風險。本探索性研究計畫的目的在於分析發展協調障礙兒童在心血管之危險因子，並長期比較正常發展兒童在健康相關因子之差異。方法：本研究以Movement ABC-2測驗篩檢141位11到12歲兒童，在評估確認發展協調障礙兒童之四個診斷條件後，9位符合確認之發展協調障礙兒童及132位正常發展兒童當成控制組，以進行Movement ABC-2測驗、Leger20公尺折返跑測驗、血壓、身體組成、肺功能，並請參與兒童自我知覺身體活動問卷(CSAPPA中文版)之結果比較。結果：本計畫發現評估發展協調障礙兒童在心血管危險因子（血壓、血脂、血糖、肺功能、有氧能力、身體組成等）與正常發展兒童進行比較後，發現發展協調障礙兒童在有氧能力較差、身體體脂肪百分比與身體質量指數值顯著較高，在其餘項目則無顯著差異；另外兩組在知覺動作能力、普遍性自我效能並無顯著差異。結論：此初步研究結果可以幫助我們了解現今台灣在發展協調障礙兒童心肺與健康行為僅略低於正常發展兒童，未來研究應進行長期追蹤的探討，以進一步了解發展協調障礙兒童在進入青少年階段之變化與影響。

Background and Purpose: Currently, there have been very limited research studies to examine cardiovascular risk factors of children with developmental coordination disorder (DCD) in the world. Several research studies have shown that physical fitness and cardiorespiratory function of children with DCD was poorer than typically developing children, and thus this may increase the cardiovascular disease (CVD) in adults when children with DCD grow up. However, no systematic examination of DCD children in this topic has been found. The purposes of this exploratory project were to analyze the cardiovascular risk factors influencing children with DCD and to compare children with DCD in health-related factors to typically developing children. Methods: Using Movement ABC-2 test, 141 school children aged 11 to 12 years were recruited for screening to identify whether DCD, borderline DCD or typical development (TD) in motor coordination. Nine children with DCD were selected with parental consents and 132 peers with TD matched were recruited as controls. All children participating in this project will attend the Movement ABC test, Leger 20-meter shuttle run in field, measures of blood pressure and body composition, and pulmonary function test. In addition, children with DCD and TD were asked to complete Children’s Self-Perception of Adequacy in and Predilection for Physical Activity Scale (CSAPPA Scale). Results: Through this investigation, we found that children with DCD were poorer in aerobic capacity and were higher in body fat and body mass index than TD children. However, no significant differences in other CVD factors between two groups were found. In addition, children with DCD were not significantly different from TD children in perceived competence and generalized self-efficacy. Conclusion: Children with DCD may less fit than TD children. Although we briefly examined the differences in CVD and health behavior between two groups, the longitudinal study to monitor children with DCD to adolescents is essential.
