摘要

目的：在探討身體活動量增加之策略介入對慢性阻塞性肺病（Chronic Obstructive Pulmonary Disease, COPD）患者之肺功能與生活品質提昇成效， 以瞭解運動介入在慢性阻塞性肺病患者族群之影響。方法：本研究評估8週身體活動量訓練計劃介入後， 對慢性阻塞性肺病患者的身體活動量、肺功能與生活品質之效益評估， 研究對象為屏東某醫療機構胸腔科門診之慢性阻塞性肺病患者22位，採立意取樣的方式進行編組， 依據研究對象之個人參與意願分成控制組（n=10）與實驗組（n=12）2組， 在實驗前進行前測， 測驗項目包括： 基本資料、健康狀況調查表、（International Physical Activity Questionnaire, IPAQ）台灣活動量調查短版問卷、生活品質問卷量表及肺功能檢測與身體活動量， 隨後實驗組以計步器監測其每日步行之步數， 並建議其每日至少步行5000步以上， 監測8週後再進行後測， 所得數據以獨立樣本t考驗及混合設計二因子變異數數分析進行檢定。結果：發現受試者肺功能檢測之FEV1與FVC數值並無顯著效益， 但生活品質之生理功能、身體健康問題、一般自覺健康狀況、活力狀況、情緒問題、心理健康與社會功能有顯著提昇效益。結論：發現身體活動量增加無法顯著改善其肺功能， 但可提昇其生活品質， 建議各醫療機構對慢性阻塞性肺病患者提昇生活品質相關治療策略時之參考。

Objective: This study investigated the effect of a walking program on pulmonary function and life quality among Chronic Obstructive Pulmonary Disease (COPD) patients, and the improvements on the quality of life after the intervention.Methods: This study evaluated the effectiveness of an 8-week physical activity intervention program to improve the physical activity tolerance, pulmonary function and quality of life of COPD patients. Subjects were recruited from a medical center in Pingtung area and were assigned to groups on purposive sampling basis. Twenty subjects were divided into two groups: 10 subjects in the control group and 12 subjects in the experimental group. Basic demographic information was collected and health condition questionnaire, International Physical Activity Questionnaire (IPAQ) physical activity questionnaire (short version), quality of life questionnaire (SF-36), pulmonary function tests (spirometry), and physical activity tests were administered at pre-test. A pedometer was used to monitor the physical activity levels of the experimental group. It was suggested that they would take at least5,000 steps each day. After the 8-week intervention period, the same post-tests were administered. Data were analyzed using the independent-samples t-tests and the mixed design two-way ANOVA tests.Results: After intervention, subjects in the experimental group showed significant improvements in quality of life areas such as physical function, role limitations due to physical problems, self-perceived general health, vitality, emotional and social functions, and mental health. Their FEV1 and FVC values, indicators of pulmonary function, did not significantly improve after the intervention.Conclusions: Increasing the amount of physical activity can improve the quality of life of the patients but not their pulmonary function. These results should be referenced when medical institutions are to consider quality-of-life related intervention strategies for patients with COPD.
