術後先天性心臟病學齡期兒童身體活動之探討
先天性心臟病為兒童常見之健康問題，隨著醫療進步，多數的先天性心臟病病童皆能在 兒童早期接受手術矯正，改善心肺功能。研究指出先天性心臟病童在手術後其運動能力 可達到與正常兒童相等的程度，但其實際身體活動程度是否能與正常兒童一樣，需進一 步瞭解，以避免日後因低身體活動造成慢性病。因此，本研究目的在探討先天性心臟病 學童與健康學童的身體活動之差異。
本研究採個案對照研究設計，以立意取樣 34 位年齡介於 9 至 12 歲並已接受完全矯 正手術之先天性心臟病兒童與 34 位健康兒童為對照組。以三日身體活動紀錄量表（ 3 d-PA ）為個案主觀身體活動評估工具， RT3 Tri-axial 加速器為客觀身體活動評估工具，連續監測三天的身體活動。
結果發現先天性心臟病男童的三日身體活動紀錄量表和 RT3 之總身體活動量皆顯著低 於健康男童（ t=-3.39, p<.05; t=-3.43, p<.05 ），並且先天性心臟病男童的身體活動程度 也顯著低於健康男童（ t=-2.29, p<.05 ），而先天性心臟病女童與健康女童的三日身體 活動紀錄量表和 RT3 之總身體活動量則無顯著差異（ t=0.58, p=.57; t=-0.27, p=.79 ），以及身體活動程度也無顯著差異（ t=-0.51, p=.61 ）。先天性心臟病男童與健康男童的 中重度身體活動量和時間無顯著差異（ t=-0.53, p=.60; t=-0.09, p=.93 ），先天性心臟病 女童與健康女童的中重度身體活動量和時間也無顯著差異（ t=0.83, p=.41; t=0.91, p=.3 7 ）。
本研究認為先天性心臟病兒童之身體活動低於健康兒童，應該鼓勵先天性心臟病兒童從 事更多身體活動尤其是中重度身體活動，本研究結果可作為日後醫療人員在指導先天性 心臟病童身體活動之參考。Physical Activity Levels of School-Aged Children With Post- Operation Congenital Heart Disease
Congenital heart disease (CHD) is a common childhood health problem. Due to medical advances, most ch ildren with CHD receive correction surgery to improve cardiopulmonary function. Evidence indicates that t heir exercise capacity can reach the level of normal children after surgical repair. However, it is necessary t o further investigate if their physical activity is comparable to their healthy peers to prevent chronic disease caused by low physical activity. The purpose of the study is to investigate the differences of physical activi ty level between health children and children after total correction for CHD.
This study is a case-control design. A purposive sampling was used to recruit thirty-four CHD children age d between 9 to 12 and thirty-four age and gender- matched children. The data collection tools included Thr ee-Day Physical Activity Record (3-d PAR) for subjective measurement and RT3 Tri-axial accelerator for objective measurement.
Total energy expenditure of 3d-PAR and RT3 were lower for CHD boys than Healthy boys (t=-3.39, p<.05
; t=-3.43, p<.05). Physical activity level was lower for CHD boys than Healthy boys (t=-2.29, p<.05). Total energy expenditure of 3d-PAR and RT3 did not differ between girls (t=0.58, p=.57; t=-0.27, p=.79). Physic al activity level did not differ between girls (t=-0.51, p=.61). The level and time of moderate-to-vigorous p hysical activity did not differ between CHD boys and Healthy boys (t=-0.53, p=.60; t=-0.09, p=.93). The le vel and time of moderate-to-vigorous physical activity did not differ between CHD girls and Healthy girls (t=0.83, p=.41; t=0.91, p=.37).
