目前，人们对怀孕期间的体力活动模式知之甚少，之前的估计主要基于容易出错的主观评估措施。鉴于肥胖率不断增加以及孕期体力活动的重要性，我们评估了主观和客观体力活动评估工具之间的关系和一致性，以告知研究人员和临床医生对孕期体力活动的最佳评估。招募了 48 名妊娠 26-28 周的孕妇。在自由生活条件下佩戴Yamax计步器和Actigraph加速度计5-7天，然后完成国际身体活动问卷（IPAQ）。将 IPAQ 和计步器的活动估计值与更可靠、更准确的加速度计数据进行比较。在招募的 48 名女性中，30 名女性完成了研究（平均年龄：33.6 ± 4.7 岁；平均 BMI：31.2 ± 5.1 kg/m2），18 名女性被排除（未佩戴 [n = 8] 和不完整数据 [n = 10]）。加速度计和计步器在每日步数估计方面显着相关（ρ = 0.69，p < 0.01），并且具有良好的绝对一致性和较低的系统误差（平均差：505 ± 1498 步/天）。加速度计和 IPAQ 估计的总代谢当量、轻度代谢当量和中度代谢当量分钟/天 (MET min-1 day-1) 没有显着相关性，且绝对一致性较差。相对于加速度计，IPAQ 低于预测的每日总 MET (105.76 ± 259.13 min-1 day-1) 和轻度 MET (255.55 ± 128.41 min-1 day-1) 以及高于预测的中度 MET (-112.25 ± 166.41 min-1 day-1)。与加速度计相比，计步器似乎可以对怀孕期间的体力活动提供可靠的估计，而主观 IPAQ 测量在这种情况下的准确度较低。未来测量怀孕期间活动的研究应该最好地包括体力活动的客观测量。澳大利亚新西兰临床试验注册号：ACTRN12608000233325。注册日期：2008 年 7 月 5 日。
Currently, little is known about physical activity patterns in pregnancy with prior estimates predominantly based on subjective assessment measures that are prone to error. Given the increasing obesity rates and the importance of physical activity in pregnancy, we evaluated the relationship and agreement between subjective and objective physical activity assessment tools to inform researchers and clinicians on optimal assessment of physical activity in pregnancy. 48 pregnant women between 26-28 weeks gestation were recruited. The Yamax pedometer and Actigraph accelerometer were worn for 5-7 days under free living conditions and thereafter the International Physical Activity Questionnaire (IPAQ) was completed. IPAQ and pedometer estimates of activity were compared to the more robust and accurate accelerometer data. Of 48 women recruited, 30 women completed the study (mean age: 33.6 ± 4.7 years; mean BMI: 31.2 ± 5.1 kg/m2) and 18 were excluded (failure to wear [n = 8] and incomplete data [n = 10]). The accelerometer and pedometer correlated significantly on estimation of daily steps (ρ = 0.69, p < 0.01) and had good absolute agreement with low systematic error (mean difference: 505 ± 1498 steps/day). Accelerometer and IPAQ estimates of total, light and moderate Metabolic Equivalent minutes/day (MET min-1 day-1) were not significantly correlated and there was poor absolute agreement. Relative to the accelerometer, the IPAQ under predicted daily total METs (105.76 ± 259.13 min-1 day-1) and light METs (255.55 ± 128.41 min-1 day-1) and over predicted moderate METs (-112.25 ± 166.41 min-1 day-1). Compared with the accelerometer, the pedometer appears to provide a reliable estimate of physical activity in pregnancy, whereas the subjective IPAQ measure performed less accurately in this setting. Future research measuring activity in pregnancy should optimally encompass objective measures of physical activity. Australian New Zealand Clinical Trial Registry Number: ACTRN12608000233325.
