中国闲暇时间体力活动问卷的建立与验证

目的建立中国闲暇时间体力活动问卷(China Leisure Time Physical Activity Questionnaire,CLTPAQ),并验证其在我国老年人群中的信效度。方法基于已在美国和西班牙人群中验证的明尼苏达州闲暇时间体力活动问卷简短版,结合中国的生活方式及文化背景建立问卷,并将其在113位65岁以上老年病人中进行验证,采用内部相关系数对问卷进行信度评价,通过分析体力活动能量消耗与身体成分、心肺功能健康指标之间的Pearson相关系数评价问卷的效度。结果两次CLTPAQ评估间的内部相关系数为0. 66～0. 90,信度较高;总能量消耗与肌肉含量(r=0. 20)、最大摄氧量(r=0. 30)呈显著正相关,与体脂百分比(r=-0. 20)呈负相关,具有较高效度。结论 CLTPAQ信效度较高,是评估我国老年人群闲暇时间体力活动可靠且有效的工具。

Development and validation of the China Leisure Time Physical Activity Questionnaire in the elderly

Objective To establish and examine the reliability and validity of the China Leisure Time Physical Activity Questionnaire(CLTPAQ)in the elderly Chinese.Methods Based on the short version of the Minnesota Leisure Time Physical Activity Questionnaire(MLTPAQ),which was validated in American and Spanish populations,a questionnaire was established based on the Chinese lifestyle and cultural background.It was validated in 113 elderly patients aged over 65 years old.The internal correlation coefficient was used to evaluate the reliability of the questionnaire.Pearson correlation coefficient between physical activity energy expenditure and body composition,cardiopulmonary health indicators was analyzed to evaluate the validity of the questionnaire.Results The internal correlation coefficients between the two CLTPAQ assessments were 0.66-0.90,with high reliability.The muscle content(r=0.20),the maximum oxygen uptake(r=0.30)showed a significant positive correlation,while body fat percentage(r=-0.20)showed a negatively correlation with total energy expenditure,which showed high validity.Conclusions CLTPAQ has high reliability and validity,and it is a reliable and valid tool to measure the leisure time physical activity of the elderly in China.
