Abstract

Objectives: Questionnaires on physical activity (PA) and physical capacity (PC) are valuable tools, as they are cost beneficial, and have high response rates. The validity of short versions of such questionnaires has not been examined satisfactorily. Therefore, we aimed at examining the validity of a set of questions coding for PA and PC.

Design: The questions were administered to 217 men and women attending a cardiac rehabilitation program. Participants also gave blood samples, measuring HDL cholesterol, triglycerides (TG), insulin, glucose, and microCRP. The relations between PA and PC and biological markers were examined by linear regression analyses.

Results: Measures for PC and for PA were identified by factor analysis, which proved internally consistent. TG, homeostatic model assessment (HOMA) score, and mCRP were all significantly associated with the measures of PC and PA.

Conclusions: The measures of PA and PC are valid compared with biological markers, allowing cost-beneficial and time-efficient evaluation of important measures for cardiovascular health.

两种自评体力活动和能力的有效测量方法。

目的:身体活动(PA)和身体能力(PC)问卷是有价值的工具，因为它们具有成本效益和高回复率。这些问卷的简短版本的有效性尚未得到令人满意的检验。因此，我们的目的是检验一组编码为PA和PC的问题的有效性。设计:对参加心脏康复计划的217名男性和女性进行了问卷调查。参与者还提供了血液样本，测量高密度脂蛋白胆固醇、甘油三酯(TG)、胰岛素、葡萄糖和微crp。采用线性回归分析检验PA、PC与生物标志物之间的关系。结果:通过因子分析确定了PC和PA的测量值，证明了内部一致。TG、稳态模型评估(HOMA)评分和mCRP均与PC和PA测量值显著相关。结论:与生物标志物相比，PA和PC的测量是有效的，可以对心血管健康的重要指标进行成本效益和时间效率的评估。
