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.
