To develop and validate a short questionnaire to estimate physical activity (PA) practice and sedentary behavior for the adult population.
The short questionnaire was developed using data from a cross-sectional population-based survey (n = 6352) that included the Minnesota leisure-time PA questionnaire. Activities that explained a significant proportion of the variability of population PA practice were identified. Validation of the short questionnaire included a cross-sectional component to assess validity with respect to the data collected by accelerometers and a longitudinal component to assess reliability and sensitivity to detect changes (n = 114, aged 35 to 74 years).
Six types of activities that accounted for 87% of population variability in PA estimated with the Minnesota questionnaire were selected. The short questionnaire estimates energy expenditure in total PA and by intensity (light, moderate, vigorous), and includes 2 questions about sedentary behavior and a question about occupational PA. The short questionnaire showed high reliability, with intraclass correlation coefficients ranging between 0.79 to 0.95. The Spearman correlation coefficients between estimated energy expenditure obtained with the questionnaire and the number of steps detected by the accelerometer were as follows: 0.36 for total PA, 0.40 for moderate intensity, and 0.26 for vigorous intensity. The questionnaire was sensitive to detect changes in moderate and vigorous PA (correlation coefficients ranging from 0.26 to 0.34).
The REGICOR short questionnaire is reliable, valid, and sensitive to detect changes in moderate and vigorous PA. This questionnaire could be used in daily clinical practice and epidemiological studies.
开发并验证一份简短问卷，以评估成年人群的身体活动（PA）情况和久坐行为。
该简短问卷是利用一项基于人群的横断面调查（n = 6352）的数据开发的，该调查包括明尼苏达休闲时间PA问卷。确定了能够解释人群PA情况变异性很大一部分的活动。简短问卷的验证包括一个横断面部分，以评估其相对于加速度计收集的数据的有效性，以及一个纵向部分，以评估其检测变化的可靠性和敏感性（n = 114，年龄在35至74岁之间）。
选择了六种活动，这些活动占明尼苏达问卷估计的PA人群变异性的87%。简短问卷估计总PA以及按强度（轻度、中度、剧烈）划分的能量消耗，并包括2个关于久坐行为的问题和1个关于职业PA的问题。简短问卷显示出高可靠性，组内相关系数在0.79至0.95之间。问卷估计的能量消耗与加速度计检测到的步数之间的Spearman相关系数如下：总PA为0.36，中度强度为0.40，剧烈强度为0.26。该问卷对检测中度和剧烈PA的变化敏感（相关系数在0.26至0.34之间）。
REGICOR简短问卷可靠、有效，且对检测中度和剧烈PA的变化敏感。该问卷可用于日常临床实践和流行病学研究。
