This study evaluates the validity of the last-7-day, self-administered version of the International Physical Activity Questionnaire (IPAQ) long form in HIV-infected people, using accelerometry as the objective criterion. The ActiGraph GT1M accelerometer was worn during all waking hours for 7 days, and the IPAQ was completed on day 7. A total of 30 men were recruited as participants from the Alfred Infectious Disease Clinic, Melbourne, Australia. Self-reported total number of metabolic equivalents minutes per week correlated moderately with accelerometer total activity counts (r = .41, p = .02). However, mean differences showed overreporting with the questionnaire; 546.63 min/wk (95% confidence interval: 217.1-871.2 minutes) for moderate and 295.33 min/wk (95% confidence interval: 88.08-502.6 minutes) for vigorous activity. The IPAQ correlated with accelerometry, but substantial overreporting occurred. The tool may be useful in screening physical activity but should not be used to determine precise levels.
本研究旨在评估国际体力活动问卷（IPAQ）长表的最后 7 天自我管理版本在 HIV 感染者中的有效性，以加速度计作为客观标准。参与者需在 7 天内全天佩戴 ActiGraph GT1M 加速度计，并在第 7 天完成 IPAQ。总共招募了 30 名男性参与者，来自澳大利亚墨尔本阿尔弗雷德传染病诊所。自我报告的每周代谢当量分钟总数与加速度计总活动计数中度相关（r =.41，p =.02）。然而，均值差异表明问卷存在过度报告；中度活动为 546.63 分钟/周（95%置信区间：217.1-871.2 分钟），剧烈活动为 295.33 分钟/周（95%置信区间：88.08-502.6 分钟）。IPAQ 与加速度计相关，但存在大量过度报告。该工具可能有助于筛查体力活动，但不应用于确定精确水平。
