We assessed the agreement between self-reported and accelerometer-assessed physical activity (PA) in African-American adults by sex, education, income, and weight status. Participants (N = 274) completed the International PA Questionnaire short form (IPAQS), Behavioral Risk Factor Surveillance System (BRFSS) PA questions, and PA Questionnaire (PAQ) and a 7-day accelerometer protocol using a waist-worn ActiGraph GT3X accelerometer. Interrelationships among PA measures were assessed by sociodemographics. Participants consistently reported doing ≥150 minutes of moderate-to-vigorous-intensity PA (MVPA) per week via self-report measures and did 113.5±179.4 minutes of accelerometer-assessed MVPA/week. Men self-reported and did more MVPA than women (p < .01). Regardless of sex, there were low correlations between self-report and accelerometer-assessed MVPA (r = .092-.190). Poor agreement existed between self-report and accelerometry for classifying participants as meeting PA recommendations (Cohen κ = .054-.136); only half of the participants were classified the same by both self-report and accelerometry. There was generally poor relative agreement between self-report and accelerometer-based assessments of MVPA in this sample of African-American adults. Findings suggest that self-report measures may perform better among African-American women than men, regardless of socioeconomic or weight status.
我们按性别、教育程度、收入和体重状况评估了非裔美国成年人自我报告的身体活动(PA)与通过加速度计评估的身体活动之间的一致性。参与者(N = 274)完成了国际身体活动问卷简表(IPAQ-SF)、行为危险因素监测系统(BRFSS)的身体活动问题、身体活动问卷(PAQ),并使用佩戴在腰部的ActiGraph GT3X加速度计进行了为期7天的加速度计测量方案。通过社会人口统计学评估身体活动测量之间的相互关系。参与者通过自我报告测量一致报告每周进行≥150分钟的中等至剧烈强度身体活动(MVPA),加速度计评估的MVPA为每周113.5±179.4分钟。男性自我报告并进行的MVPA比女性更多(p <.01)。无论性别如何,自我报告与加速度计评估的MVPA之间的相关性都很低(r =.092 -.190)。在将参与者分类为符合身体活动建议方面,自我报告与加速度计测量之间的一致性较差(Cohen κ =.054 -.136);只有一半的参与者在自我报告和加速度计测量中被分类相同。在这个非裔美国成年人样本中,自我报告与基于加速度计的MVPA评估之间的相对一致性普遍较差。研究结果表明,无论社会经济或体重状况如何,自我报告测量在非裔美国女性中可能比男性表现更好。
