研究目的：七日回憶問卷已廣泛使用於西方國家，並顯示良好的信度與效度；然而這項問卷在台灣地區使用的情形尚未有報告。本研究的目的是檢驗中文版七日回憶活動量問卷在停經後婦女骨質較低者及心臟疾病患者使用的信度，以及其與最大攝氧量和疾病的相關性。方法：受試者為20位停經後婦女骨密度檢查低於常模值1標準差以下（骨質較低）以及23位心臟疾病患者。重測信度間隔2個月進行；並檢測其與患者漸進式運動測試結果的相關性。統計方式包括ICC和Spearman相關係數檢定。結果：兩組的每一個活動量範疇與整體活動能量消耗的重測信度是中度到佳。骨質較低組每個活動範疇的ICC為0.52-0.72；而心臟疾病組為0.67-0.90。兩組整體活動能量消耗以kcal.d^(-1) or kcal.d^(-1).kg^(-1)表示時ICC結果也都是佳（骨質較低組為0.83、0.64；心臟疾病組為0.98、0.91; p<0.01）。問卷計算之能量消耗與最高攝氧量和負荷量只在心臟疾病組有統計上顯著相關(r=0.70和0.68, p<0.01)。能量消耗與骨密度及左心室射出率都無顯著相關(p>0.05)。結論：本研究結果顯示七日活動量問卷是評估台灣地區骨質較低患者和心臟患者活動量的一項可信工具。但其與疾病的相關性並不顯著。

Purposes: The purposes of this study were to examine the reliability of the 7-day(7-d) recall physical activity questionnaire and its correlation with peak oxygen consumption (VO(subscript 2peak)) in osteopenic patients and cardiac patients, and to determine its relationship with impairment associated with these conditions Methods: Twenty postmenopausal women with bone mineral density (BMD) below 1 standard deviation of the normal range (osteopenia group) and 23 subjects with cardiac disease (4 women and 19 men) were included in this study. Test-retest reliability of the 7-d recall physical activity questionnaire vas examined at to months VO(subscript 2peak) derived from graded exercise test as compared with energy cost derived from the 7-d recall questionnaire Intra-class correlation coefficient (ICC) and Spearman correlation coefficient were used for data analysis. Results: Test-retest reliability in each activity category and total energy expenditure v as moderate to good in both groups. The ICC for different activity levels as in the range of 0.52-0.72 in the osteopenia group, and 0.67-0.90 (p<0.01) in the cardiac disease group. Total energy expenditure in kcal.d^(-1) or kcal.d^(-1).kg^(-1) vas also significantly consistent in the osteopenia group (ICC=0.83, 0.64, p<0.01) and in the cardiac disease group (ICC=0.98, 0.91, p<0.01). In patients with cardiac disease, a significant correlation vas found between energy expenditure and VO(subscript 2peak)(r=0.70, p<0.01) as well as peak workload (r=0.68, p<0.01). There as no significant correlation between energy expenditure and BMD or left ventricular ejection fraction (LVEF) (r=0.08 and -0.06, p>0.05) Conclusions: The results of this study indicate that the Chinese version of the 7-d recall physical activity questionnaire is a reliable tool for assessing physical activity in Taiwanese with cardiac disease However, it as not correlated with the degree of BMD or LVEF.
