Shift work have been thought to restrict participation in leisure time activities, but the knowledge about physical activity in rotating night shift nurses has been limited so far. We investigated the associations between the rotating night shift work and physical activity using data from a cross-sectional study among nurses and midwives. This study included 354 nurses and midwives (aged 40-60) currently working rotating night shifts and 371 ones working days only. The information on the work characteristics and potential covariates was collected via a personal interview. Weight and height were measured and BMI was calculated. Physical activity was assessed according to the international questionnaire on physical activity - IPAQ, and four domains: leisure time, occupational, transport related and household were analyzed. Women who reported none leisure time activity were defined as recreationally "inactive". The associations were examined with multiple linear or logistic regression models adjusted for age, season of the year, number of full term births, marital status and BMI. Total and occupational physical activity was significantly higher among nurses working rotating night shifts. However, leisure time activity was significantly affected among rotating night shift nurses and midwives, compared to women working during the days only, with increased odds ratio for recreational "inactivity" (OR = 1.57, 95% CI: 1.11-2.20). Rotating night shift work among nurses and midwives is associated with higher occupational physical activity but lower leisure time activity. Initiatives supporting exercising among night shift workers are recommended.
轮班工作被认为会限制参与休闲活动，但迄今为止，关于轮班夜班护士身体活动的了解还很有限。我们利用一项针对护士和助产士的横断面研究数据，调查了轮班夜班工作与身体活动之间的关联。这项研究包括354名目前从事轮班夜班工作的护士和助产士（年龄在40至60岁之间）以及371名仅上白班的人员。通过个人访谈收集了工作特征和潜在协变量的信息。测量体重和身高并计算体重指数（BMI）。根据国际身体活动问卷（IPAQ）评估身体活动情况，并对休闲时间、职业、交通相关和家务四个领域进行分析。报告没有休闲时间活动的女性被定义为在娱乐方面“不活跃”。使用针对年龄、一年中的季节、足月分娩次数、婚姻状况和BMI进行调整的多元线性或逻辑回归模型来检验这些关联。从事轮班夜班工作的护士的总体和职业身体活动明显更高。然而，与仅上白班的女性相比，轮班夜班护士和助产士的休闲时间活动受到显著影响，娱乐“不活跃”的比值比增加（OR = 1.57，95%置信区间：1.11 - 2.20）。护士和助产士的轮班夜班工作与较高的职业身体活动相关，但休闲时间活动较低。建议采取措施支持夜班工作者进行锻炼。
