Since prevalence estimates of recommended physical activity (PA) considerably vary between different surveys, prevalence might be crucially affected by the choice of measuring instrument. The aim of the present study is to compare the results of four PA questionnaires regarding the current moderate- and vigorous-intensity aerobic PA (MVPA) recommendations of the World Health Organization.
Within an online survey, participants answered the German Health Interview and Examination Survey for Adults (DEGS), the European Health Interview Survey PA Questionnaire (EHIS), the Eurobarometer (EURO), and a single-item measure (SIM). Weekly volume of MVPA was compared via a Friedman test and the prevalence of participants achieving the WHO's MVPA recommendation via Cochran's Q. Agreement between all questionnaire pairs was evaluated via Kappa statistics.
One hundred seventy-six participants were included in the analyses (70.5% female, mean age: 33.1 years (SD=12.2)). Between the four questionnaires, the weekly volume of MVPA statistically significant differed (SIM: MED=90.0 (MIN=0.0, MAX=210.0), DEGS: MED=120.0 (MIN=0.0, MAX=420.0), EHIS: MED=24.0 (MIN=0.0, MAX=1395.0), EURO: MED=51.0 (MIN=0.0, MAX=2430.0), p<.001, all pairwise comparisons p<.01), as well as the prevalence of participants achieving the MVPA recommendations (SIM 31.3% (95% CI 24.5-38.7), DEGS 43.2% (95% CI 35.8-50.8), EHIS 67.0% (95% CI 59.6-73.9), EURO 87.5% (95% CI 81.7-92.0), p<.001), except between SIM and DEGS (p=.067). Agreement was weak between all questionnaire pairs (all κ< 0.60).
Questionnaire choice crucially affects the resulting MVPA data and hence the prevalence of achieving recommended PA levels within the same sample. Therefore, for PA surveillance, standardised survey and analysis methods and efforts to harmonise monitoring systems are needed, since whether recommended levels of PA are achieved should not be determined by the choice of one measuring instrument or another.
由于不同调查中推荐体力活动（PA）的流行率估计差异很大，因此流行率可能会受到测量工具选择的极大影响。本研究的目的是比较四个 PA 问卷的结果，以了解它们与世界卫生组织（WHO）当前的中等强度和高强度有氧 PA（MVPA）推荐值之间的关系。
在一项在线调查中，参与者回答了德国成人健康访谈和体检调查（DEGS）、欧洲健康访谈调查 PA 问卷（EHIS）、欧洲民意调查（EURO）和单项测量（SIM）。通过 Friedman 检验比较每周 MVPA 量，通过 Cochran 的 Q 检验比较达到 WHO MVPA 推荐量的参与者的流行率。通过 Kappa 统计评估所有问卷对之间的一致性。
共有 176 名参与者被纳入分析（70.5%为女性，平均年龄 33.1 岁[SD=12.2]）。四个问卷之间每周 MVPA 量的差异具有统计学意义（SIM：中位数=90.0（最小值=0.0，最大值=210.0），DEGS：中位数=120.0（最小值=0.0，最大值=420.0），EHIS：中位数=24.0（最小值=0.0，最大值=1395.0），EURO：中位数=51.0（最小值=0.0，最大值=2430.0），p<.001，所有两两比较 p<.01），以及达到 MVPA 推荐量的参与者的流行率（SIM 为 31.3%（95%CI 24.5-38.7），DEGS 为 43.2%（95%CI 35.8-50.8），EHIS 为 67.0%（95%CI 59.6-73.9），EURO 为 87.5%（95%CI 81.7-92.0），p<.001），除了 SIM 和 DEGS 之间（p=.067）。所有问卷对之间的一致性都很弱（所有 κ<0.60）。
问卷选择极大地影响了 MVPA 数据的结果，因此也影响了同一样本中达到推荐 PA 水平的流行率。因此，需要进行标准化的调查和分析方法以及努力协调监测系统，因为是否达到推荐的 PA 水平不应取决于一种测量工具的选择。
