ABSTRACT

Populations working night shift are high risk for diet-related chronic illness which may result from circadian misalignment. Studies documenting nutritional habits among night shift workers have relied on inaccurate approximations of dietary intake. The primary purpose of this pilot study was to gather feasibility information regarding the use of a free electronic food diary application, MyFitnessPal, to document on-duty and off-duty eating habits among nurses working 12-h night shift. Secondary aims included comparing average daily intake of nutrients when on-duty versus off-duty and to compare average daily sugar intake to national recommendations for sugar intake. A total of 16 nurses participated with 92% compliance for nutritional logging using the application. Nurses reported significantly more calories consumed from sugar on average when compared to national recommendations both when off-duty (m = 293.5 kcal vs. 173.1 kcal) and on-duty (m = 273.0 kcal vs. 180.4 kcal). No significant differences were detected in self-reported macronutrient consumption within-subjects for on-duty versus off-duty conditions. MyFitnessPal may be feasible for night shift nurses to track dietary intake. Future studies should explore on-duty and off-duty diet and related health outcomes among nurses who work night shifts.

摘要

夜班工作的人群是与饮食有关的慢性疾病的高风险，这可能是由于昼夜节律紊乱所致。记录夜班工人营养习惯的研究依赖于不精确的饮食摄入量。这项初步研究的主要目的是收集有关使用免费电子食品日记应用程序MyFitnessPal的可行性信息，以记录工作12小时夜班的护士的上班和下班饮食习惯。次要目标包括在上班和下班时比较平均每日营养摄入量，并将平均每日糖摄入量与国家建议的糖摄入量进行比较。共有16名护士使用该应用程序进行了92％的营养记录合规性检查。与国家建议相比，护士在下班时（m = 293.5 kcal与173.1 kcal）和在上班时间（m = 273.0 kcal与180.4 kcal）相比，从糖中平均消耗的卡路里要多得多。在上班和下班条件下，受试者自我报告的常量营养素消耗量之间没有显着差异。MyFitnessPal对于夜班护士跟踪饮食摄入可能是可行的。未来的研究应该探讨夜班护士的上班和下班饮食以及相关的健康结局。MyFitnessPal对于夜班护士跟踪饮食摄入可能是可行的。未来的研究应该探讨夜班护士的上班和下班饮食以及相关的健康结局。MyFitnessPal对于夜班护士跟踪饮食摄入可能是可行的。未来的研究应该探讨夜班护士的上班和下班饮食以及相关的健康结局。
