The physiological impact of transitioning from full-time study to work in occupations that involve high-stress environments and shift work may plausibly impact sleep patterns and quality. There are limited studies focusing on the transition to shift work in graduate paramedics. This study aimed to assess early metabolic markers of health, activity, and sleep quality during the first 5 months of rostered shift work in a cohort of 28 graduate paramedics. Participants were tested for 4-week blocks before starting shift work (baseline), and during their first and fifth month of shift work. In each block, sleep and activity levels were monitored 24 h/day (workdays and nonworking days) using a wrist-worn actigraph. During shift work, the number of sleep episodes increased by 16.7% (p = .02) and self-reporting of poor sleep quality increased by 35.4% (p = .05); however, overall sleep quantity and sleep efficiency did not differ. Sleep metrics recorded during nonwork days were not different to baseline with exception of reduced sleep duration recorded the night before returning to work (5.99 ± 1.66 hours Month 1; 5.72 ± 1.06 hours Month 5). Sedentary behavior increased by 4.8% across the study, attributable to a significant decline in light exercise (p = .05). No changes were recorded in vigorous physical activity, average steps recorded per day, fasting blood glucose levels, systolic and diastolic blood pressure, weight, or waist circumference. These results warrant further large-scale and longitudinal studies to gauge any physiological implications for ongoing paramedic health.
从全职学习过渡到从事高压力环境和轮班工作的职业，可能会对睡眠模式和质量产生影响。目前，针对毕业生急救员过渡到轮班工作的研究有限。本研究旨在评估 28 名毕业生急救员在轮班工作的前 5 个月期间，健康、活动和睡眠质量的早期代谢指标。在开始轮班工作之前（基线）和轮班工作的第一个和第五个月，参与者进行了为期 4 周的测试。在每个测试块中，使用腕戴式活动记录仪 24 小时/天（工作日和非工作日）监测睡眠和活动水平。在轮班工作期间，睡眠时间增加了 16.7%（p=.02），自我报告的睡眠质量差增加了 35.4%（p=.05）；然而，整体睡眠时间和睡眠效率没有差异。非工作日的睡眠指标与基线相比没有差异，但在返回工作前一天的睡眠时间减少了（第 1 个月 5.99±1.66 小时；第 5 个月 5.72±1.06 小时）。整个研究期间，久坐行为增加了 4.8%，这归因于轻度运动的显著下降（p=.05）。剧烈身体活动、平均每天记录的步数、空腹血糖水平、收缩压和舒张压、体重或腰围均无变化。这些结果需要进一步的大规模和纵向研究来评估对持续的急救员健康的任何生理影响。
