国际体力活动问卷（IPAQ）是为了测量人群中与健康相关的体力活动（PA）而开发的。IPAQ的简短版本已经过广泛测试，现在被用于许多国际研究。本研究的目的是探讨长期版IPAQ.Subjects和方法的有效性特征46自愿健康男性和女性受试者（年龄，平均值+/-标准差：40.7 +/- 10.3年）参加了这项研究。结果IPAQ的活动监测数据与IPAQ的活动监测数据呈显著正相关，IPAQ的活动监测数据与IPAQ的活动监测数据呈显著正相关（rho=0.55，P < 0.001）和剧烈PA（rho=0.71，P < 0.001），但中度PA（rho=0.21，P=0.051）的相关性较弱。PA日志中计算的MET-h天（-1）与IPAQ中的MET-h天（-1）显著相关（rho=0.67，P < 0.001）。总PA的IPAQ数据与有氧健身（rho=0.21，P=0.051）和BMI（rho=0.25，P=0.009）之间存在弱相关性。体脂百分比和IPAQ变量之间没有显著相关性。Bland-Altman分析表明，无法检测到某些类型的活动的活动监视器可能会引入一个源的标准validationstudies.Conclusions的错误，长期的，自我管理的IPAQ问卷具有可接受的有效性时，评估水平和模式的PA在健康成人。
Introduction The International Physical Activity Questionnaire (IPAQ) was developed to measure health-related physical activity (PA) in populations. The short version of the IPAQ has been tested extensively and is now used in many international studies. The present study aimed to explore the validity characteristics of the long-version IPAQ.Subjects and methods Forty-six voluntary healthy male and female subjects (age, mean +/- standard deviation: 40.7 +/- 10.3 years) participated in the study. PA indicators derived from the long, self-administered IPAQ were compared with data from an activity monitor and a PA log book for concurrent validity, and with aerobic fitness, body mass index (BMI) and percentage body fat for construct validity.Results Strong positive relationships were observed between the activity monitor data and the IPAQ data for total PA (rho=0.55, P < 0.001) and vigorous PA (rho=0.71, P < 0.001), but a weaker relationship for moderate PA (rho=0.21, P=0.051). Calculated MET-h day(-1) from the PA log book was significantly correlated with MET-h day(-1) from the IPAQ (rho=0.67, P < 0.001). A weak correlation was observed between IPAQ data for total PA and both aerobic fitness (rho=0.21, P=0.051) and BMI (rho=0.25, P=0.009). No significant correlation was observed between percentage body fat and IPAQ variables. Bland-Altman analysis suggested that the inability of activity monitors to detect certain types of activities might introduce a source of error in criterion validation studies.Conclusions The long, self-administered IPAQ questionnaire has acceptable validity when assessing levels and patterns of PA in healthy adults.
