This study aimed to evaluate the agreement between self-reported physical activity (PA) levels, as measured by the Lipid Research Clinics Physical Activity Questionnaire (LRCQ), and objective measures obtained through actigraphy in people with HIV.
Cross-sectional data were analyzed from the 130 people with HIV who completed the LRCQ and wore an actigraphy device for 7-10 days. The agreement between the LRCQ and actigraphy was assessed using various interrater agreement metrics, including Cohen's kappa and percentage agreement.
The predominantly male (67.7%) cohort had a mean age of 55.7 ± 10.6 years. The LRCQ categorized 51.5% of participants as low activity; however, 33% of those self-reporting low activity achieved over 150 min of moderate to vigorous PA weekly measured by actigraphy. Agreement metrics indicated a "fair" level of concordance: Percentage agreement was 67%, and Cohen's kappa was 0.29 ( P < 0.001).
The LRCQ does not accurately capture PA levels in people with HIV compared to actigraphy. This discrepancy suggests potential under- or over-reporting, emphasizing caution in using self-reported data for clinical assessments. Future research should focus on refining PA questionnaires and integrating objective measures to enhance the accuracy of PA evaluations in this population.
本研究旨在评估通过脂质研究诊所身体活动问卷（LRCQ）测量的自我报告身体活动（PA）水平与通过活动记录仪在HIV感染者中获得的客观测量结果之间的一致性。
对130名完成LRCQ并佩戴活动记录仪7 - 10天的HIV感染者的横断面数据进行分析。使用包括科恩kappa系数和百分比一致性在内的各种评分者间一致性指标评估LRCQ与活动记录仪之间的一致性。
以男性为主（67.7%）的队列平均年龄为55.7±10.6岁。LRCQ将51.5%的参与者归类为低活动水平；然而，在那些自我报告为低活动水平的人中，33%通过活动记录仪测量每周进行中度至剧烈PA超过150分钟。一致性指标表明一致性水平为“中等”：百分比一致性为67%，科恩kappa系数为0.29（P<0.001）。
与活动记录仪相比，LRCQ不能准确反映HIV感染者的PA水平。这种差异表明可能存在报告不足或过度报告的情况，强调在临床评估中使用自我报告数据时要谨慎。未来的研究应专注于改进PA问卷并整合客观测量方法，以提高该人群PA评估的准确性。
