背景：没有标准化的方法来评估体力活动（PA）。因此，研究不同措施的有效性和可比性非常重要。国际体力活动问卷 (IPAQ) 是作为跨国体力活动评估工具而开发的，并已在 12 个国家得到验证。这些仪器具有可接受的测量特性，可用于监测不同环境中 18-65 岁成年人的 PA 人群水平。然而，有人担心 IPAQ 可能会过度报告 PA。本研究的目的是评估 IPAQ（简短版）最近 7 天在 Nord-Trondelag 健康研究 (HUNT) 男性人群中的可靠性和有效性。方法：对 108 名 20-39 岁男性随机样本进行两次问卷调查，并通过与 VO2max 和 ActiReg（一种测量 PA 和能量消耗 (EE) 的工具）比较结果来验证有效性。 ActiReg 区分身体姿势：站立、坐下、前弯和躺着，并且还会记录每个姿势或两者是否有运动。 结果：我们的 IPAQ 简短版本的可靠性结果对于剧烈活动良好，对于中等活动则较好。组内相关性范围从中等活动时间的低值 0.30 到静坐时间的高值 0.80。关于有效性，我们的结果表明，总 IPAQ 剧烈 PA 是衡量剧烈活动的较好指标，与 VO2max 具有中等强度的显着相关性，r = 0.41 (p
Background: There is no standardized method for the assessment of physical activity (PA). Therefore it is important to investigate the validity and comparability of different measures. The International Physical Activity Questionnaire (IPAQ) has been developed as an instrument for cross-national assessment of PA and has been validated in 12 countries. These instruments have acceptable measurement properties for monitoring population levels of PA among 18-65 year-old adults in diverse settings. However, there are some concerns that IPAQ may over-report PA.The purpose of this study is to evaluate the reliability and validity of IPAQ, short version, last 7-days in the Nord-Trondelag Health Study ( HUNT) population of men.Methods: The questionnaire was administered twice to a random sample of 108 men aged 20-39 and validity by comparing results with VO2max and ActiReg, an instrument that measures PA and energy expenditure (EE). ActiReg discriminates between the body positions: stand, sit, bend forward and lie and also registers if there is motion or not in each of them or both.Results: Our results for reliability of the IPAQ short version were good for vigorous and fair for moderate activities. Intraclass correlations ranged from a low of 0.30 for moderate activity hours, to a high of 0.80 for sitting hours. Concerning validity, our results suggest that total IPAQ vigorous PA was a moderately good measure of vigorous activity, having moderately strong, significant correlations with VO2max, r = 0.41 (p
