BACKGROUND
Little is known about the associations of resting heart rate (RHR) and heart rate reserve (HRR) with metabolic syndrome (MetS) in firefighters.
METHODS
For each of 288 professional firefighters, HRR was calculated as the difference between measured RHR and estimated maximum HR. For comparison, VO max based on a treadmill test was included. MetS was defined according to the NCEP/ATP III criteria.
RESULTS
The prevalence of MetS was 14.2%. The average of RHR was 61.5 beat/min. Only 5.8% of the firefighters had RHR of ≥80 beat/min. Between the firefighters in the lowest and highest quintiles, the prevalence ratios (95% confidence intervals) for MetS were 1.88 (0.71-4.94), 5.90 (1.74-20.02), and 8.03 (1.86-34.75) for RHR, HRR, and VO max, respectively. Both HRR and VO max, but not RHR, were significantly associated with MetS and its most component risk factors in middle-aged firefighters.
CONCLUSIONS
HRR, a simple cardiovascular fitness measure, was inversely associated with MetS among middle-aged professional firefighters.
背景
关于静息心率 (RHR) 和心率储备 (HRR) 与消防员代谢综合征 (MetS) 的相关性，目前知之甚少。
方法
对于 288 名专业消防员中的每一位，HRR 是通过测量的 RHR 和估计的最大 HR 之间的差值计算得出的。为了进行比较，还包括基于跑步机测试的 VO max。MetS 根据 NCEP/ATP III 标准定义。
结果
MetS 的患病率为 14.2%。RHR 的平均值为 61.5 次/分。只有 5.8%的消防员的 RHR 大于等于 80 次/分。在 RHR 最低和最高五分位数的消防员中，MetS 的患病率比 (95%置信区间) 分别为 1.88(0.71-4.94)、5.90(1.74-20.02)和 8.03(1.86-34.75)，分别为 RHR、HRR 和 VO max。HRR 和 VO max，但不是 RHR，与中年消防员的 MetS 及其大多数组成风险因素显著相关。
结论
HRR，一种简单的心血管健康测量指标，与中年专业消防员的 MetS 呈负相关。
