Previous research points to some inappropriate nutritional habits among nurses working night shifts. However, the knowledge of specific nutritional components of their diet has been limited. In the present study, we aimed to investigate the association between rotating night shifts of nurses and midwives and their usual dietary intake of energy and nutrients. A cross-sectional study was conducted among 522 Polish nurses and midwives: 251 working rotating night shifts (i.e. working night shift followed by a day off on a subsequent day) and 271 day workers. Polish adaptation of the Food Frequency Questionnaire, regarding 151 food items, was used to assess the usual dietary energy and nutrient intake. Data on occupational history and potential confounders were collected via face-to-face interviews. Body weight, height, waist and hip circumference were measured. Linear regression models: univariate (crude) and multivariate (adjusted) were run, with the nutrient intake as dependent variables, night work characteristics, and important confounders. Among nurses and midwives working rotating night shifts, a significantly higher adjusted mean intake was found for the total energy (2005 kcal vs 1850 kcal) and total fatty acids (77.9 g vs 70.4 g) when compared to day workers, as well as for cholesterol (277 mg vs 258 mg), carbohydrates (266 g vs 244 g) and sucrose (55.8 g vs 48.6 g). Night shift work duration was inversely related to the consumption of calcium, phosphorus, vitamin A, vitamin C and % energy from proteins. The higher energy consumption may contribute to increase risk of overweight and obesity among nurses working night shifts.
先前的研究表明，倒班护士存在一些不当的营养习惯。然而，对于他们饮食中特定营养成分的了解有限。在本研究中，我们旨在调查护士和助产士轮班夜班与他们通常的饮食能量和营养素摄入之间的关系。我们对 522 名波兰护士和助产士进行了横断面研究：251 名轮班夜班（即上夜班，随后第二天休息）和 271 名白班工人。使用波兰版的食物频率问卷，对 151 种食物进行了评估，以评估通常的饮食能量和营养素摄入。通过面对面访谈收集职业史和潜在混杂因素的数据。测量体重、身高、腰围和臀围。运行了线性回归模型：单变量（粗）和多变量（调整），将营养素摄入量作为因变量，夜班工作特征和重要混杂因素作为自变量。与白班工人相比，轮班夜班的护士和助产士的总能量（2005 千卡比 1850 千卡）和总脂肪酸（77.9 克比 70.4 克）、胆固醇（277 毫克比 258 毫克）、碳水化合物（266 克比 244 克）和蔗糖（55.8 克比 48.6 克）的调整后平均摄入量明显更高。夜班工作时间与钙、磷、维生素 A、维生素 C 和蛋白质供能百分比的消耗呈负相关。更高的能量消耗可能会增加夜班护士超重和肥胖的风险。
