Emergency nurses work consecutive, rotating shift patterns. However, how their occupational physical activity levels are associated between these shifts is unknown. This study aimed to examine the associations between emergency nurses' time spent in different activity levels across one shift and the following day's shift.
Fifty emergency nurses (45 female, five male) wore an ActiGraph accelerometer and completed work and sleep diaries across four weeks in 2018. A sub-sample (n = 42) also wore an activPAL inclinometer. Time spent sedentary, physically active, and in postural positions was determined. Multi-level analyses examined associations between one shift and the following day's shift.
Additional time spent sedentary and in light-intensity physical activity during the first shift was associated with more time spent being physically active in the following day's shift for all rotations except back-to-back night shifts. However, additional time spent engaged in moderate- to vigorous-intensity physical activity during the first shift was associated with less time spent physically active in the following day's shift for afternoon-morning and morning-afternoon rotations.
These findings demonstrate that shift sequences may impact emergency nurses' physical activity across shifts. Future research should identify the strategies emergency nurses use to maintain activity levels between shifts.
急诊护士连续轮班工作。然而，目前尚不清楚他们在轮班之间的职业体力活动水平如何相关。本研究旨在检验急诊护士在一个班次内不同活动水平上所花费的时间与第二天班次之间的关联。
2018 年，50 名急诊护士（45 名女性，5 名男性）佩戴 ActiGraph 加速度计，并在四周内完成工作和睡眠日记。一个子样本（n=42）还佩戴了 activPAL 测斜仪。确定了久坐、身体活跃和姿势位置的时间。多水平分析检验了一个班次与第二天班次之间的关联。
在第一个班次中额外的久坐和低强度体力活动时间与除了连续夜班之外的所有班次中第二天的体力活动时间增加有关。然而，在第一个班次中额外的中等到剧烈强度体力活动时间与第二天的体力活动时间减少有关，适用于下午到上午和上午到下午的班次。
这些发现表明，班次顺序可能会影响急诊护士在轮班之间的体力活动水平。未来的研究应该确定急诊护士在轮班之间保持活动水平的策略。
