術後先天性心臟病學齡期兒童身體活動之探討
Physical Activity Levels of School-Aged Children With Post-Operation Congenital Heart Disease
中文摘要
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（3d-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=.37）。
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。
英文摘要
Congenital heart disease (CHD) is a common childhood health problem. Due to medical advances, most children with CHD receive correction surgery to improve cardiopulmonary function. Evidence indicates that their exercise capacity can reach the level of normal children after surgical repair. However, it is necessary to 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 activity 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 aged between 9 to 12 and thirty-four age and gender-
matched children. The data collection tools included Three-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). Physical activity level did not differ between girls (t=-0.51, p=.61). The level and time of moderate-to-vigorous physical activity did not differ between CHD boys and Healthy boys (t=-0.53, p=.60;
t=-0.09, p=.93). The level 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).
These results suggest that children with CHD engage in less physical activity than Health children. Hence, CHD children should be encouraged to engage in more physical activity especially moderate-to-vigorous physical activity. It can be used as clinical references for health professionals to physical activity among children with CHD.
