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.

本研究的目的是检查来自拉丁美洲国家的成年人的自我报告和基于设备的久坐行为 (SB) 测量与肥胖标志物之间的关联。使用两个不同的问卷自我报告了在不同 SBs 的就座时间和总时间。加速度计用于评估总久坐时间。评估体重指数、腰围和颈围。自我报告的久坐时间最高的是阿根廷，在不同 SB 中花费的总时间最高的是巴西和哥斯达黎加，而基于设备的久坐时间最高的是秘鲁。自我报告的坐姿时间、在不同 SB 上花费的总时间或基于设备的久坐时间都与体重指数无关。基于设备的久坐时间与腰围呈正相关，而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之间的关联时，需要谨慎。
