Shift work is often associated with adverse effects on cardiovascular health of employees. Only a few studies address the strain of shift and day workers on non-working days compared to working days.
This study aims to determine how the cardiovascular strain of hotel and catering industry (HCI) employees who work alternating shifts differs from those working normal day shifts-on both a working day (WD) and a non-working day (ND).
The sample consisted of 60 alternating shift (morning and afternoon, mean age: 31.5 ± 8.5 years) and 88 day workers (mean age: 35.3 ± 9.4 years). A 24-h ambulatory measurement of blood pressure (BP) and heart rate (HR) on WD and ND with the time phases DAY, SLEEP, and 24-h TOTAL was used to analyse cardiovascular strain. BP status was assessed by self-measurement (36% hypertensives).
The total strain over 24 h was slightly higher on WD than ND (mean BP: 134/79 versus 127/75 mmHg, P = 0.002-0.020; mean HR: 78 versus 75 bpm, P = 0.055). In trend, shift workers had higher systolic BP than day workers during the individual time phases of DAY, SLEEP, and 24-h TOTAL on WD. Known cardiovascular risk factors emerged as critical determinants of cardiovascular strain: older age, male gender, and hypertensive blood pressure status.
The results revealed no clear association between the alternating shift system in HCI and increased cardiovascular strain. The 24-h ambulatory measurement is considered ideal for determining cardiovascular strain in everyday life and under working conditions.
轮班工作通常与员工心血管健康的不良影响有关。只有少数研究探讨了轮班和白班工人在非工作日与工作日相比的非工作日压力。
本研究旨在确定从事酒店和餐饮行业（HCI）轮班工作的员工的心血管压力与从事正常白班工作的员工（早上和下午，平均年龄：31.5±8.5 岁）有何不同）-在工作日（WD）和非工作日（ND）。
该样本包括 60 名轮班工人（上午和下午，平均年龄：31.5±8.5 岁）和 88 名白班工人（平均年龄：35.3±9.4 岁）。使用 24 小时动态血压（BP）和心率（HR）监测，在 WD 和 ND 上测量白天、睡眠和 24 小时总时间的变化，以分析心血管压力。BP 状况通过自我测量（36%的高血压患者）进行评估。
WD 上的总压力略高于 ND（平均 BP：134/79 与 127/75mmHg，P=0.002-0.020；平均 HR：78 与 75bpm，P=0.055）。在趋势上，WD 上，轮班工人在白天、睡眠和 24 小时总时间的各个时间阶段的收缩压均高于白班工人。已知心血管危险因素是心血管压力的关键决定因素：年龄较大、男性和高血压血压状况。
结果表明 HCI 中的交替班次系统与增加的心血管压力之间没有明确的关联。24 小时动态监测被认为是确定日常生活和工作条件下心血管压力的理想方法。
