The purpose of this study was to examine the associations between self-reported and device-based measures of sedentary behavior (SB) with obesity markers in adults from Latin American countries. Sitting time and total time spent in different SBs were self-reported using two different questionnaires. Accelerometers were used to assess total sedentary time. Body mass index, waist, and neck circumferences were assessed. The highest self-reported sitting time was in Argentina, the highest total time spent in different SBs was in Brazil and Costa Rica, and the highest device-based sedentary time was observed in Peru. Neither self-reported sitting time, total time spent in different SBs or device-based sedentary time were associated with body mass index. Device-based sedentary time was positively associated with waist circumference and self-reported sitting time was positively associated with neck circumference. Caution is warranted when comparing the associations of self-reported and device-based assessments of SB with anthropometric variables.
本研究旨在探讨拉丁美洲成年人中自我报告和基于设备的久坐行为 (SB) 测量指标与肥胖标志物之间的关联。使用两种不同的问卷自我报告坐姿时间和不同 SB 中花费的总时间。使用加速度计评估总久坐时间。评估了体重指数、腰围和颈围。报告的最高坐姿时间是在阿根廷，花费在不同 SB 中的最高总时间是在巴西和哥斯达黎加，观察到的基于设备的最高久坐时间是在秘鲁。自我报告的坐姿时间、不同 SB 中花费的总时间或基于设备的久坐时间均与体重指数无关。基于设备的久坐时间与腰围呈正相关，自我报告的坐姿时间与颈围呈正相关。在比较自我报告和基于设备的 SB 评估与人体测量变量的关联时需要谨慎。
