This study evaluates the validity and reliability of the Baecke questionnaire on habitual physical activity when applied to a population of HIV/AIDS subjects. Validity was determined by comparing measurements for 30 subjects of peak oxygen uptake, peak workload, and energy expenditure with scores for occupational physical activity (OPA), physical exercise in leisure (PEL), leisure and locomotion activities (LLA), and total score (TS). Reliability was determined by testing and retesting 29 subjects at intervals of 15-30 days. Validity was evaluated with the Pearson correlation and reliability analyses were done using the intraclass correlation, paired Student t-test, and Bland-Altman methods. Peak VO2 and peak workload had significant correlation with PEL (r = 0.41; r = 0.43; respectively). Energy expenditure had a significant correlation with OPA (r = 0.64). The intraclass coefficients were 0.70 or more for OPA, PEL and TS. There was no difference in OPA, PEL, LLA and TS between the two evaluations. The Bland-Altman methods showed that there was good agreement between the measurements for all habitual physical activities scores. Results show that the Baecke questionnaire is valid for the evaluation of habitual physical activity among people living with HIV/AIDS.
本研究评估了贝克体力活动问卷应用于艾滋病毒/艾滋病患者群体时的有效性和可靠性。通过比较30名受试者的峰值摄氧量、峰值工作量和能量消耗测量值与职业体力活动（OPA）、休闲体育锻炼（PEL）、休闲和运动活动（LLA）得分及总分（TS）来确定有效性。通过对29名受试者进行间隔15 - 30天的重复测试来确定可靠性。使用Pearson相关性评估有效性，采用组内相关性、配对学生t检验和Bland - Altman方法进行可靠性分析。峰值VO2和峰值工作量与PEL有显著相关性（分别为r = 0.41；r = 0.43）。能量消耗与OPA有显著相关性（r = 0.64）。OPA、PEL和TS的组内系数为0.70或更高。两次评估之间的OPA、PEL、LLA和TS没有差异。Bland - Altman方法表明，所有习惯性体力活动得分的测量值之间具有良好的一致性。结果表明，贝克问卷对于评估艾滋病毒/艾滋病感染者的习惯性体力活动是有效的。
