The U.S. National Health and Nutrition Examination Survey (NHANES) physical activity monitor datasets for 2011–12 and 2013–14 were released in late 2020. To date, there has been limited interpretation of these nationally representative wrist‐worn accelerometer data (summarized and reported in Monitor Independent Movement Summary [MIMS] units) and their relationships with health‐related outcomes. This study examined the associations between free‐living DailyMIMS (volume), Peak 1MIMS and Peak 30MIMS (intensity), and risk of Metabolic Syndrome (MetS). Data from adults (N=3787; 18–80+ years) in the 2011–12 and 2013–14 NHANES cycles with health examination and accelerometry data were included. Accelerometer data were processed into Peak 1MIMS and Peak 30MIMS (MIMS/min), and DailyMIMS (MIMS/day). Design‐based generalized linear and logistic regressions, and a sample‐weighted decision tree, were used to examine associations between MIMS variables and MetS risk factors. Lower Peak 1MIMS, Peak 30MIMS, and DailyMIMS were observed for every one‐unit increase in the number of risk factors −3.9 [95% CI: −4.3, −3.4] and −2.3 [−2.6, −2.1] MIMS/min, (−672.1 [−772.7, −571.5] MIMS/day, respectively, all p< 0.001). The Decision Tree classified individuals ≥ 46.5 years with a DailyMIMS ≥ 12 245 MIMS/day and a Peak 30MIMS < 45.1 MIMS/min as having MetS (≥ 3 risk factors). Individuals < 46.5 years with a Peak 1MIMS ≥ 62.9 MIMS/min were classified with 0 risk factors. Higher DailyMIMS and PeakMIMS were associated with an absence of MetS risk factors, with a progressive decline as the number of risk factors increased. These findings may be considered as preliminary benchmarks for DailyMIMS and PeakMIMS associated with cardiometabolic risk.

与代谢综合征相关的每日和峰值监测独立运动摘要 （MIMS） 值：NHANES 2011-12 和 2013-14


2011-12 年和 2013-14 年的美国国家健康和营养检查调查 （NHANES） 身体活动监测数据集于 2020 年底发布。迄今为止，对这些具有全国代表性的腕戴式加速度计数据（在监测独立运动摘要 [MIMS] 单位中总结和报告）及其与健康相关结果的关系的解释有限。本研究检查了自由生活的 DailyMIMS（体积）、峰值 1MIMS 和峰值 30MIMS（强度）与代谢综合征 （MetS） 风险之间的关联。包括 2011-12 和 2013-14 NHANES 周期中来自成人 （N=3787;18-80+ 岁） 的数据，包括健康检查和加速度测量数据。将加速度计数据处理为峰值 1MIMS 和峰值 30MIMS （MIMS/min） 以及 DailyMIMS （MIMS/天）。基于设计的广义线性和 logistic 回归以及样本加权决策树用于检查 MIMS 变量与 MetS 风险因素之间的关联。风险因素数量每增加一个单位，观察到较低的峰值 1MIMS、峰值 30MIMS 和 DailyMIMS：-3.9 [95% CI：-4.3、-3.4] 和 -2.3 [-2.6、-2.1] MIMS/min，（分别为 -672.1 [-772.7、-571.5] MIMS/天，均 p< 0.001）。决策树将 46.5 岁、每日 MIMS ≥ 12 245 MIMS/天和峰值 30MIMS < 45.1 MIMS/min 的≥个体分类为具有 MetS（≥ 3 个危险因素）。个体 < 46.5 岁，峰值 1MIMS ≥ 62.9 MIMS/min，被归类为 0 个危险因素。较高的 DailyMIMS 和 PeakMIMS 与不存在 MetS 危险因素相关，随着危险因素数量的增加，风险因素逐渐下降。这些发现可被视为与心脏代谢风险相关的 DailyMIMS 和 PeakMIMS 的初步基准。
