Abstract: Use of wearable devices that monitor physical activity is projected to increase more than fivefold per half-decade1. We investigated how device-based physical activity energy expenditure (PAEE) and different intensity profiles were associated with all-cause mortality. We used a network harmonization approach to map dominant-wrist acceleration to PAEE in 96,476 UK Biobank participants (mean age 62 years, 56% female). We also calculated the fraction of PAEE accumulated from moderate-to-vigorous-intensity physical activity (MVPA). Over the median 3.1-year follow-up period (302,526 person-years), 732 deaths were recorded. Higher PAEE was associated with a lower hazard of all-cause mortality for a constant fraction of MVPA (for example, 21% (95% confidence interval 4–35%) lower hazard for 20 versus 15kJkg1d1 PAEE with 10% from MVPA). Similarly, a higher MVPA fraction was associated with a lower hazard when PAEE remained constant (for example, 30% (8–47%) lower hazard when 20% versus 10% of a fixed 15kJkg1d1 PAEE volume was from MVPA). Our results show that higher volumes of PAEE are associated with reduced mortality rates, and achieving the same volume through higher-intensity activity is associated with greater reductions than through lower-intensity activity. The linkage of device-measured activity to energy expenditure creates a framework for using wearables for personalized prevention.

据悉，预计每5年可监测身体活动的穿戴设备将增加五倍以上。

这些结果表明，较高量的PAEE与降低的死亡率有关，与强度较低的活动相比，强度较高的活动在相同量下可以带来更大好处。设备测量的活动与能量消耗的联系为使用可穿戴设备进行个性化预防创建了一个框架。

研究人员调查了基于设备的体育活动能量消耗（PAEE）和不同强度的概况如何与全因死亡率相关。研究人员使用网络协调方法，将96476名英国生物银行参与者（平均年龄62岁，女性为56％）的优势腕加速度映射到PAEE。研究人员还计算了从中等强度到剧烈强度的体育活动（MVPA）积累的PAEE的比例。在3.1年的中位随访期（302,526人年数）中，记录到732例死亡。对于恒定比例的MVPA，较高的PAEE与较低的全因死亡率危险性相关。同样，当PAEE保持恒定时，较高的MVPA分数与较低的危害相关。
