这项研究是为了评估对轮班工作表现出不同长期耐受性的轮班工人在昼夜节律调整和/或某些行为特征上是否有所不同。根据是否有与倒班工作相关的投诉，(1)没有投诉；(2)神经性投诉(焦虑/抑郁，严重睡眠障碍)；(3)消化障碍(胃十二指肠炎，消化性溃疡)，选择了三组工人，每组8人，在一家印刷厂进行三班制，年龄和工作经验匹配。他们回答了关于家庭状况、健康状况、睡眠习惯僵化、克服困倦、早晨和明显焦虑的能力的问卷调查。他们还记录了白天和夜间轮班的几个生理参数(口腔温度、握力、最大呼气流速、脉率、睡眠小时数)。获得的数据表明，睡眠习惯的灵活性、克服困倦的能力和较低的显性焦虑的特征与对倒班工作的更好耐受性有关。这些特点似乎并不影响口腔温度昼夜交替的昼夜节律的调节。相反，清晨似乎与长期耐受性无关，但确实影响了昼夜节律调整和睡眠行为。在这些人群中，患有消化障碍的受试者在夜间工作时表现出更大的相移和幅度降低，这表明，正如其他作者指出的那样，短期的昼夜节律调整与长期对倒班工作的耐受性之间也可能存在关系。
The study was carried out to evaluate whether shiftworkers showing different long-term tolerance to shiftwork differ in their circadian adjustments and/or in some behavioural characteristics. Three groups of eight workers, engaged on three shifts in a graphic plant and matched for age and work experience, were selected acording to the presence or not of complaints related to shiftwork: (1) no complaints; (2) nervous complaints (anxiety/depression, severe sleep disturbances); (3) digestive disorders (gastroduodenitis, peptic ulcer). They answered questionnaires on family conditions, health status, rigidity of sleeping habits, ability to overcome drowsiness, morningness, manifest anxiety. They also recorded several physiological parameters (oral temperature, grip strength, peak expiratory flow rate, pulse rate, sleep hours) during day and night-shifts. The data obtained indicate that the characteristics of flexibility of sleeping habits, ability to overcome drowsiness, and lower manifest anxiety, are associated with better tolerance to shiftwork. These characteristics do not seem to influence the adjustment of the circadian rhythm of oral temperature passing from day to night-shifts and vice versa. Conversely, morningness appeared to be unrelated to long-term tolerance, but did influence circadian adjustments and sleep behaviour. Among the groups, the subjects with digestive disorders showed a greater phase shift and a reduction of the amplitude on night-work, suggesting a possible relationship also between the short-term circadian adjustment and the long-term tolerance to shiftwork, as pointed out by other authors.
