需要可行、成本效益高的工具来监测中等到剧烈的体力活动(MVPA)和久坐行为(SB)，并评估干预措施的效果。然而，世界卫生组织认可的全球体力活动问卷(GPAQ)的有效性和可靠性的证据基础是有限的。我们的目的是评估GPAQ在测量和评估MVPA和SB变化方面与加速计数据的有效性。参与者(n=101)是从一项正在进行的研究中随机挑选出来的，按体力活动水平(基于GPAQ的低、中或高活动水平)和性别进行分层。参与者佩戴加速计(Actigraph GT3X)7天，并在第7天完成GPAQ。在3-6个月后的第二个时间点，对随机的子样本重复该方案。分析包括测量差异的Wilcoxon符号等级检验，MVPA中位数和SB mins/day测量之间的一致性的Bland-Altman分析，以及标准有效性和变化程度的Spearman的Rho系数。95名参与者完成了基线测量(44名女性，51名男性；平均年龄44岁，(SD 14)；计算了41名(21名女性，20名男性；平均年龄46岁，SD 14)的变化测量值。GPAQ与加速度计的MVPA分钟/天符合程度为中等(r=0.48)，SB的一致性较差(r=0.19)。MVPA的绝对平均差(自我报告减去加速计)为−0.8分钟/天，SB为348.7分钟/天；并且发现存在负面偏见，那些更多体力活动的人高报了他们的MVPA水平：那些更久坐的人不太可能少报他们的Sb水平。随时间变化的一致性结果显示，与MVPA呈中度相关(r=0.52p=0.12)，与SB呈弱相关(r=−0.024，p=0.916)。与客观测量的一致性水平表明，GPAQ是MVPA和MVPA变化的有效衡量标准，但不是当前水平和SB变化的有效衡量标准。因此，GPAQ似乎是评估促进MVPA的干预措施有效性的适当衡量标准。
Feasible, cost-effective instruments are required for the surveillance of moderate-to-vigorous physical activity (MVPA) and sedentary behaviour (SB) and to assess the effects of interventions. However, the evidence base for the validity and reliability of the World Health Organisation-endorsed Global Physical Activity Questionnaire (GPAQ) is limited. We aimed to assess the validity of the GPAQ, compared to accelerometer data in measuring and assessing change in MVPA and SB. Participants (n = 101) were selected randomly from an on-going research study, stratified by level of physical activity (low, moderate or highly active, based on the GPAQ) and sex. Participants wore an accelerometer (Actigraph GT3X) for seven days and completed a GPAQ on Day 7. This protocol was repeated for a random sub-sample at a second time point, 3–6 months later. Analysis involved Wilcoxon-signed rank tests for differences in measures, Bland-Altman analysis for the agreement between measures for median MVPA and SB mins/day, and Spearman’s rho coefficient for criterion validity and extent of change. 95 participants completed baseline measurements (44 females, 51 males; mean age 44 years, (SD 14); measurements of change were calculated for 41 (21 females, 20 males; mean age 46 years, (SD 14). There was moderate agreement between GPAQ and accelerometer for MVPA mins/day (r = 0.48) and poor agreement for SB (r = 0.19). The absolute mean difference (self-report minus accelerometer) for MVPA was −0.8 mins/day and 348.7 mins/day for SB; and negative bias was found to exist, with those people who were more physically active over-reporting their level of MVPA: those who were more sedentary were less likely to under-report their level of SB. Results for agreement in change over time showed moderate correlation (r = 0.52, p = 0.12) for MVPA and poor correlation for SB (r = −0.024, p = 0.916). Levels of agreement with objective measurements indicate the GPAQ is a valid measure of MVPA and change in MVPA but is a less valid measure of current levels and change in SB. Thus, GPAQ appears to be an appropriate measure for assessing the effectiveness of interventions to promote MVPA.
