Based on a 4-day questionnaire survey for all meals and snacks consumed by female workers in a computer factory in Japan, consisting of 44 daytime workers and 93 weekly-rotating shift workers (of whom 47 and 46 were engaged in, respectively, early-shift work and late-shift work during the survey week), the present study aimed to clarify the effects of shift work on their nutrient intakes in association with food consumption patterns. Their dietary intakes for 3 working days and an off day were assessed by self-registered food consumption records with the aid of a photographic method, and intakes of energy, protein, fat, carbohydrate, calcium and iron were estimated. The inter-group differences were prominent in the working days. The shift workers, particularly the late-shift workers, took smaller amounts of energy and nutrients than the daytime workers, implying that the former group's nutritional status has been worsened, judged from the recommended dietary allowance for Japanese. Their inadequate nutrient intake was due to lower meal frequency and poor meal quality, both of which were conditioned by shift work.
基于对日本一家计算机工厂女职工所有餐食和零食进行的为期4天的问卷调查，该工厂有44名日班工人和93名轮班工人（在调查周期间，其中47人和46人分别从事早班工作和晚班工作），本研究旨在阐明轮班工作与食物消费模式相关联时对她们营养摄入的影响。借助摄影法，通过自我记录的食物消费记录评估她们在3个工作日和1个休息日的饮食摄入量，并估算能量、蛋白质、脂肪、碳水化合物、钙和铁的摄入量。工作日期间组间差异显著。轮班工人，尤其是晚班工人，摄入的能量和营养素比日班工人少，这意味着从日本的膳食推荐摄入量来看，前一组的营养状况已经恶化。她们营养摄入不足是由于进餐频率较低和膳食质量较差，而这两者均受轮班工作的影响。
