Sleep deprivation can lead to increased body weight and blood pressure (BP), but the latent effects of partial sleep deprivation related to required night sentry duties within a short-term period on cardiometabolic characteristic changes in military personnel are unclear.
To investigate the association between night sentry duty frequency in the past 3 months and cardiometabolic characteristics in armed forces personnel.
A total of 867 armed forces personnel who were aged 18-39 years and did not take any antihypertensive medications in Taiwan in 2020 were included. The frequency of night sentry duty was self-reported a questionnaire (average number of night sentry shifts per month for the past 3 months). Hemodynamic status was assessed the resting BP and pulse rate (PR). Cardiometabolic risk factors were defined according to the International Diabetes Federation criteria. Multivariable linear regression analyses of the associations between night sentry duties and PR, BP, and other metabolic syndrome (MetS) marker levels were performed, with adjustments for age, sex, substance use, body mass index and aerobic fitness. Multiple logistic regression analysis was carried out to determine the associations between night sentry duties and the prevalence of each MetS feature.
There was an association between night sentry duties and PR [standardized β (standard error) = 0.505 (0.223), =0.02], whereas there was no association with systolic and diastolic BP. In addition, there was an inverse association between night sentry duties and high-density lipoprotein cholesterol (HDL-C) levels [standardized β = -0.490 (0.213), = 0.02], whereas there was no association with the other metabolic marker levels. Compared with personnel without night sentry duties, those with ≥ 1 night sentry shift/month had a greater risk of impaired fasting glucose (≥ 100 mg/dL) [odds ratio: 1.415 (confidence interval: 1.016-1.969)], whereas no associations with other MetS features were found.
Among military personnel, the burden of night sentry duty was positively associated with the resting PR but inversely associated with HDL-C levels. In addition, personnel with partial sleep deprivation may have a greater risk of impaired fasting glucose than those without partial sleep deprivation.
睡眠剥夺可导致体重增加和血压升高，但短期内与夜间站岗值班相关的部分睡眠剥夺对军事人员心脏代谢特征变化的潜在影响尚不清楚。
探讨过去3个月夜间站岗值班频率与武装部队人员心脏代谢特征之间的关联。
纳入2020年台湾地区867名年龄在18 - 39岁且未服用任何降压药物的武装部队人员。通过问卷调查自我报告夜间站岗值班频率（过去3个月每月夜间站岗班次的平均数）。通过静息血压和脉搏率评估血流动力学状态。根据国际糖尿病联盟标准定义心脏代谢危险因素。对夜间站岗值班与脉搏率、血压及其他代谢综合征（MetS）标志物水平之间的关联进行多变量线性回归分析，并对年龄、性别、物质使用情况、体重指数和有氧适能进行校正。进行多因素logistic回归分析以确定夜间站岗值班与各MetS特征患病率之间的关联。
夜间站岗值班与脉搏率之间存在关联[标准化β（标准误）= 0.505（0.223），P = 0.02]，而与收缩压和舒张压无关联。此外，夜间站岗值班与高密度脂蛋白胆固醇（HDL-C）水平呈负相关[标准化β = -0.490（0.213），P = 0.02]，而与其他代谢标志物水平无关联。与无夜间站岗值班的人员相比，每月≥1次夜间站岗班次的人员空腹血糖受损（≥100 mg/dL）的风险更高[比值比：1.415（置信区间：1.016 - 1.969）]，而未发现与其他MetS特征存在关联。
在军事人员中，夜间站岗值班负担与静息脉搏率呈正相关，但与HDL-C水平呈负相关。此外，部分睡眠剥夺的人员空腹血糖受损的风险可能高于无部分睡眠剥夺的人员。
