A shift from self-reports to wearable sensors for global physical activity (PA) surveillance has been recommended. The conventional use of a generic cut-point to assess moderate-to-vigorous PA (MVPA) is problematic as these cut-points are often derived from non-representative samples under non-ecological laboratory conditions. This study aimed to develop age- and sex-specific (age-sex) cut-points for MVPA based on population-standardized values as a feasible approach to assess the adherence to PA guidelines and to investigate its associations with all-cause mortality.

基于人群标准化值开发加速度计年龄和性别特异性方法进行身体活动监测：概念验证


有人建议从自我报告转向可穿戴传感器进行全球身体活动 （PA） 监测。传统上使用通用切割点来评估中度至强力 PA （MVPA） 是有问题的，因为这些切割点通常来自非生态实验室条件下的非代表性样品。本研究旨在根据人群标准化值开发 MVPA 的年龄和性别特异性 （age-） 切点，作为评估 PA 指南依从性并调查其与全因死亡率关联的可行方法。
