背景-本研究的目的是验证总活动测量，一个简短的问卷，以衡量身体活动在老年人人口与heartdisease.Methods两个版本的总活动测量管理两次，7天分开。总活动测量1要求受访者每周在三个不同强度水平下进行身体活动的频率和平均持续时间，而总活动测量2要求受访者每周在每个活动水平上进行活动的总时间。问卷的准确性进行了研究，在62名男性和15名女性，年龄在47-84岁，通过重复性和比较两个管理的总活动量测量1和总活动量测量2与7天的RT 3加速度计data.Results七十三个成年人（58名男性，15名女性）被用于所有的统计分析。总活动测量1和总活动测量2总活动评分（每分钟代谢当量）的组内相关系数分别为r=0.73（95%置信区间，0.56-0.83）和r=0.82（95%置信区间，0.71-0.88）。总活动测量1和RT 3加速度计之间的相关性对于总活动评分（每分钟代谢当量）是显著的，对于中等强度活动，在时间1处r=0.26，在时间2处r=0.27。总活动测量2和RT 3加速度计之间的总活动评分（每分钟代谢当量）的相关性也是显著的，对于剧烈强度活动，时间1的r = 0.38，时间2的r= 0.36，时间2的r=0.31，对于中等强度活动，时间1的r =0.29，时间2的r=0.25。参与者高估了两份问卷的体力活动量相比，RT 3 accelerometer.Conclusions的总活动量2是相当准确的评估总强度和中等强度的活动超过7天的时间，并表现出良好的重测信度。总活动测量1不太准确。总活动测量2是用于成年心脏病人群调查和审核的总或中等强度体力活动的合适测量。
Background The aim of this study was to validate the Total Activity Measure, a brief questionnaire, to measure physical activity in an older adult population with heart disease.Methods Two versions of the Total Activity Measure were administered twice, 7 days apart. The Total Activity Measure 1 asked respondents for the frequency and average duration of bouts of physical activity at three different intensity levels per week, whereas the Total Activity Measure 2 asked respondents for the total time spent in activity at each activity level per week. Questionnaire accuracy was studied in 62 men and 15 women aged 47-84 years, by repeatability and comparison of both administrations of the Total Activity Measure 1 and Total Activity Measure 2 with 7-day RT3 accelerometer data.Results Seventy-three adults (58 men, 15 women) were used for all statistical analyses. Intraclass correlation coefficients for the Total Activity Measure 1 and Total Activity Measure 2 total activity scores (metabolic equivalent per minute) were r=0.73 (95% confidence intervals, 0.56-0.83) and r=0.82 (95% confidence intervals, 0.71-0.88), respectively. Correlations between the Total Activity Measure 1 and RT3 accelerometer for total activity score (metabolic equivalent per minute) were significant, r=0.26 at time 1 and r=0.27 at time 2 for moderate intensity activities. Correlations between the Total Activity Measure 2 and RT3 accelerometer for total activity score (metabolic equivalent per minute) were also significant, r=0.38 at time 1 and r=0.36 attime 2, r=0.31 attime 2 for strenuous intensity activities and r=0.29 attime 1 and r=0.25 attime 2 for moderate intensity activities. Participants overestimated the amount of physical activity on both questionnaires as compared with the RT3 accelerometer.Conclusions The Total Activity Measure 2 was reasonably accurate in assessing total and moderate intensity activity over a 7-day period and demonstrated good test-retest reliability. The Total Activity Measure 1 was less accurate. The Total Activity Measure 2 is a suitable measure of total or moderate intensity physical activity for surveys and audits in an adult cardiac population.
