大多数妊娠研究都依赖于回顾性的横断面调查来衡量身体活动水平。调查表具有成本效益，但数据的有效性可能值得怀疑。Objective.本研究的目的是使用便携式活动监测仪（ActiReg（R））验证体力活动和妊娠问卷（PAPQ）。设计前瞻性比较研究。设置.在首都地区招募的健康孕妇。人口77名孕妇连续7天在清醒时佩戴ActiReg（R）传感器，并回答PAPQ。主要结果指标。通过Bland-Altman图和斯皮尔曼相关系数分析两种方法之间的一致性。结果结果显示，PAPQ和ActiReg（R）在总体力活动水平和符合现行运动指南的参与者比例的交叉表中只有微小差异。高强度活动（METS > 6）时间相关性良好（r = 0.59），站立/移动时间相关性中等（r = 0.36），坐卧时间相关性一般（r = 0.29）。活动模式的Bland-Altman图显示平均差异接近零，无明显趋势，个体观察结果分散。结论. PAPQ可以被认为是一种可接受的方法，用于评估孕妇在群体水平上的习惯性体力活动和运动。然而，由于问卷调查和便携式活动监测仪在测量身体活动的不同方面具有优势，因此将这两种类型的仪器结合起来用于登记怀孕期间的身体活动水平可能具有优势。
Most pregnancy-studies have relied on retrospective, cross-sectional surveys to measure physical activity level. Questionnaires are cost-effective, but validity of the data may be questionable. Objective. The aim of the present study was to validate a physical activity and pregnancy questionnaire (PAPQ) with a portable activity monitor (ActiReg(R)). Design. Prospective comparison study. Setting. Healthy pregnant women recruited in a capital area. Population. Seventy-seven pregnant women wore the ActiReg(R) sensors during waking hours for seven consecutive days and answered the PAPQ. Main outcome measures. Agreement between the two methods was analyzed by Bland-Altman plots and Spearman correlation coefficients. Results. The results indicated only small differences between the PAPQ and the ActiReg(R) in cross-tabulation of total physical activity level and proportion of participants meeting the current exercise guidelines. The correlation between the methods was good (r = 0.59) for time spent in activities with high intensity (METS > 6), moderate for time spent standing/moving (r = 0.36) and fair for sitting/lying (r = 0.29). The Bland-Altman plot of the activity patterns, showed a mean difference near zero with no apparent trends and wide scatter of individual observations. Conclusions. The PAPQ may be considered an acceptable method for assessing habitual physical activity and exercise among pregnant women at group level. However, as questionnaires and portable activity monitors have their strengths in measuring different aspects of physical activity, there may be advantages in combining these two types of instruments for registrations of physical activity level during pregnancy.
