The purpose of this study was to assess the validity of the Human Activity Profile (HAP) by comparing scores with accelerometer data and by objectively testing its cutoff points. This study included 120 older women (age 60-90 years). Average daily time spent in sedentary, moderate, and hard activity; counts; number of steps; and energy expenditure were measured using an accelerometer. Spearman rank order correlations were used to evaluate the correlation between the HAP scores and accelerometer variables. Significant relationships were detected (rho = .47-.75, p < .001), indicating that the HAP estimates physical activity at a group level well; however, scatterplots showed individual errors. Receiver operating characteristic curves were constructed to determine HAP cutoff points on the basis of physical activity level recommendations, and the cutoff points found were similar to the original HAP cutoff points. The HAP is a useful indicator of physical activity levels in older women.
本研究的目的是通过将分数与加速度计数据进行比较，并客观测试其临界点，来评估人类活动概况（HAP）的有效性。本研究纳入了120名老年女性（年龄60 - 90岁）。使用加速度计测量久坐、中度和剧烈活动的平均每日时长、计数、步数以及能量消耗。采用Spearman等级相关来评估HAP分数与加速度计变量之间的相关性。检测到显著关系（rho = 0.47 - 0.75，p < 0.001），表明HAP在群体水平上能很好地估计身体活动；然而，散点图显示存在个体误差。根据身体活动水平建议构建受试者工作特征曲线以确定HAP临界点，所发现的临界点与原始HAP临界点相似。HAP是老年女性身体活动水平的一个有用指标。
