“…The maximum permissible mean heart rate of 8-hour work in women aged from 30 to 39 and from 40 to 49 is similar and estimated at 110 beats/min 15) . The mean heart rate of matrons in the present study is more similar to the estimated maximum permissible level than the results of Shimaoka et al 12) for nursery teachers and Fujiwara 13) for hospital nurses. They suggested that a reduction in working time, reconsideration of arrangements, maintenance of a daily schedule and improvement of working conditions are necessary.…”

In the present study, the total energy expenditure of matrons in each shift work was higher than that of nursery teachers 12) and hospital nurses 13) .

In order to find out the work load of matrons under shift work in a special nursing home for the elderly (SNH), six healthy female matrons volunteered to participate in the present study. For each subject, care working time, heart rate, walking steps, estimated energy expenditure and working time in different postures were determined during day shift work (540 min) and night shift work (960 min). Although the time on duty, working and recess were significantly longer in night shift work than day shift work, the percentages of working and recess time to duty time were nearly the same regardless of shift work. The longest care work in each shift work was individual care of residents in the SNH. The maximum, minimum and mean heart rate and percentages to estimated maximal heart rate were similar in each shift work. Although total walking steps in night shift work were significantly larger than those in day shift work, steps per hour did not differ between them. The estimated total energy expenditure (kcal) was significantly higher in night shift work than in day shift work; however, the work intensity (kcal/kg/min) was significantly higher in day shift work. The longest length and larger percentage of working time were observed in standing posture in each shift work. These findings suggest that physical activity and energy expenditure of matrons under either shift work in the SNH seem to be high. Further studies are needed to clarify the work load of matrons engaged in SNH to formulate countermeasures.

Objectives The purpose of this study was to determine whether shift work affects the heart-rate-adjusted QT interval (QTc) in electorcardiography (ECG) and the blood pressure of workers without overt cardiovascular dysfunction. Methods At a copper smelter, 158 shift workers and 75 day workers who underwent an ECG examination and blood pressure measurements in 1986 were followed for 10 years. In 1996, biochemical indicators such as highdensity lipoprotein cholesterol and triglycerides were measured, together with the QTc. Resuits In 1986 and 1996, the QTc was significantly longer in the shift workers than in the day workers. Of 180 workers with a normal QTc (<420 ms112) in 1986,15% had developed aprolonged QTc (420 m~l /~) in 1996 (18% of the 117 shift workers and 11% of the 63 day workers). Among the workers with a normal QTc in 1986, the shift workers had a significantly longer QTc than the day workers when the QTc was examined in 1996. In addition, shift-day work in the group with a normal QTc was significantly related to the QTc in 1996 after control for age, work duration, biochemical indicators, smoking, and drinking habits. However, the blood pressures of the shift and day workers did not differ significantly, and in 1996 the values of both groups were significantly elevated. COIIC~US~OIIS These data suggest that shift work is associated with QTc prolongation. This evidence may explain the increased risk for cardiovascular diseases due to shift work.Key terms blood pressure, cardiovascular effect, heart rate-adjusted QT interval, shift work.

IMPORTANCEThe association of fast backward-rotating shift work (ie, anticlockwise sequence of afternoon, morning, and night shifts) with subjective and objective measures of sleep-wake quality, daytime attention, and tiredness of health care workers has not yet been established. OBJECTIVE To investigate the association of shift rotation direction with tiredness, sleepiness, and sustained attention among nurses working forward-and backward-rotating shifts. DESIGN, SETTING, AND PARTICIPANTS Data of this cohort study were collected from nurses working at 5 midsized Italian hospitals. The nurses had either a forward-rotating schedule (ie, morning to afternoon to night) and or a backward-rotating schedule (ie, afternoon to morning to night). The data were collected from July 2017 to February 2020. Data analysis was performed from May to October 2020. EXPOSURES Participants were working either forward-or backward-rotating schedules, in which the sequence of 3 shifts (morning, afternoon, and night) changed in a clockwise or anticlockwise direction. MAIN OUTCOMES AND MEASURES Sleep data were collected using the Karolinska Sleepiness Scale and Pittsburgh Sleep Quality Index. Sustained attention was measured using the Psychomotor Vigilance Task. Tiredness was evaluated using the Tiredness Symptom Scale. RESULTS A total of 144 nurses (mean [SE] age, 41.3 [0.8] years; 92 women [63.9%]) participated in the study; 80 nurses had forward-rotating schedules, and 64 had backward-rotating schedules.Nurses with irregular sleep-wake patterns due to night shift work had poor sleep quality (46 [57.5%] in forward-rotating schedule group; 37 [57.8%] in backward-rotating schedule group). Nurses working backward-rotating shifts exhibited significantly greater sleepiness (F 1,139 = 41.23; P < .001) and cognitive slowing (ie, longer median reaction times; F 1,139 = 42.12; P < .001) than those working forward rotations. Importantly, these differences were not affected by age, years of employment, and quality of sleep. Of nurses working on a backward-rotating schedule, 60 (93.8%) reported elevated sleepiness (Karolinska Sleepiness Scale score Ն7) after the night shift. The median reaction time (F 1,139 = 42.12; P < .001), 10% fastest reaction time (F 1,139 = 97.07; P < .001), minor lapses (F 1,139 = 46.29; P < .001), and reaction time distribution (F 1,139 = 60.13; P < .001) of nurses on backward-rotating schedules indicated a lower level of vigilance, which is negatively associated with neurobehavioral performance. CONCLUSIONS AND RELEVANCEIn this study, both shift rotation models were negatively associated with health and cognitive performance. These findings suggest that forward shift rotation may be more beneficial than backward rotation for several measured performance attentional (continued) Key Points Question Among hospital staff who work day and night shifts, do sleep and attention metrics vary between those who work forward-vs backwardrotating shifts? Findings This cohort study of 144 nurses found that fast forward-rotating shifts...
