轮班工作与营养和健康问题有关。在本研究中，采用基于 24 小时膳食记录并适应巴西饮食环境的饮食调查方法，对巴西弗洛里亚诺波利斯市的垃圾收集者的食物摄入量进行了调查。比较了三个不同的班次（上午、下午和晚上）（每班 n = 22）。所有组的年龄、体重和体重指数（BMI）相似。三班倒的每日能量消耗都很高，尤其是早班工人。尽管食物选择和昼夜节律摄入节律不同，但每日能量摄入量没有差异。能量摄入量很高，接近之前报道的运动员水平。与轮班无关的几个因素对摄入量有显着影响：一天中的时间、距离上一顿饭的时间、年龄和体重指数。根据营养成分对摄入的食物进行分组分析。转变显着影响淀粉、酒精饮料和糖果的摄入量。在一天中的不同时段，食物和营养素的摄入量受到轮班的显着影响。食物选择和营养摄入的昼夜节律分布分析对于轮班工人来说很重要，因为每日总摄入量可能无法揭示与轮班相关的差异。 (C) 2003 Elsevier Science Ltd. 保留所有权利。
Shift work is associated with nutritional and health problems. In the present study, the food intake of garbage collectors of the city of Florianopolis (Brazil) was investigated using a dietary survey method based on meal recording during 24 h and adapted for the Brazilian food context. Three different shifts (morning, afternoon, and night) were compared (n = 22 per shift). Age, body weight and body mass index (BMI) were similar for all groups. Daily energy expenditure was high in all three shifts, especially in morning shift workers. No difference in daily energy intake was found, in spite of differences in food choices and circadian ingestion rhythms. Energy intake was high and close to levels previously reported in athletes. Several factors not associated with shifts had significant impact on ingestion: hour of the day, time since the last meal, age, and BMI. Ingested foods were analyzed in groups based on nutrient content. Shifts significantly influenced intake of starches, alcoholic drinks, and sweets. In different periods of the day, food and nutrient intake were considerably affected by shifts. The analysis of circadian distribution of food choices and nutrient intake is important in shift workers, because total daily intake may not reveal shift-associated differences.
