Many studies investigated adverse effects of rotating shift work, deriving from modifications of circadian rhythms and alimentary behaviours. This may cause the disregulation of glycolipidic metabolism and of insulin secretion, and the development of central obesity. We conducted the present study in order to assess the differences in body mass index (BMI) between day and shift workers, in relation to diet quality and physical activity.
The study included 341 male subjects (165 day workers and 176 shift workers). Body weight, height, BMI, waist and hip circumferences were measured. Physical activity and diet quality were assessed by self-reported questionnaires.
Shift workers had higher BMI than day workers (27.6 +/- 3.9 vs 26.7 +/- 3.6), and this correlation persisted after adjustment for age. The diet quality was better in shift workers and the level of physical activity was similar in the two groups.
The results of this study indicate that shift work is an independent risk factors in the development of overweight and central obesity. In fact, although the diet quality was even better in shift workers, and the level of physical activity was similar between day and shift workers, we found that shift workers had higher BMI.
许多研究调查了轮班工作的不良影响，这些影响源于昼夜节律和饮食行为的改变。这可能导致糖脂代谢和胰岛素分泌失调，以及中心性肥胖的发展。我们进行本研究是为了评估日班工人和轮班工人之间体重指数（BMI）的差异，以及与饮食质量和身体活动的关系。
该研究纳入了341名男性受试者（165名日班工人和176名轮班工人）。测量了体重、身高、BMI、腰围和臀围。通过自我报告问卷评估身体活动和饮食质量。
轮班工人的BMI高于日班工人（27.6±3.9 vs 26.7±3.6），且在调整年龄后这种相关性仍然存在。轮班工人的饮食质量更好，两组的身体活动水平相似。
本研究结果表明，轮班工作是超重和中心性肥胖发展的独立危险因素。事实上，尽管轮班工人的饮食质量更好，且日班工人和轮班工人的身体活动水平相似，但我们发现轮班工人的BMI更高。
