The effects of circadian typology on sleep-wake behavior in shiftworkers were investigated using wrist actigraph in 18 air traffic controllers (ATC), nine morning types and nine evening types, working in a backward 1-1-1 super rapid rotation shift schedule. The ATC wore a wrist actigraph continuously over 6 days (3 days on duty and 3 days off duty). Evening types presented more flexible sleep habits and slept significantly less than morning types. Regardless of circadian typology, the morning shift tended to reduce the amount of sleep whereas night shift produced a decrease in daily activity.
使用腕部活动记录仪对18名空中交通管制员(ATC)进行了调查,研究昼夜节律类型对轮班工作者睡眠-觉醒行为的影响。这18名管制员中,9人为早起型,9人为晚睡型,他们采用向后1-1-1超快速轮班时间表工作。ATC连续6天佩戴腕部活动记录仪(3天值班,3天休息)。晚睡型表现出更灵活的睡眠习惯,且睡眠时间明显少于早起型。无论昼夜节律类型如何,早班往往会减少睡眠时间,而夜班则会导致日常活动量减少。
