We evaluated the eating pattern, physical activity, and daytime sleepiness level in Chilean shift workers. Fifty, middle-aged adult health workers from a public hospital in Santiago, Chile, were included: a group undergoing shift work (shift workers, including at least one "night shift" and one "long day", n = 33), and day workers under traditional schedule (from 8:00 to 17:00h, n = 17). Body composition, physical activity, and daytime sleepiness levels, and diet characteristics (diet composition, meals' timing, and diet quality) were assessed. Despite similar total energy intake, shift worker showed lower carbohydrate (% of energy) and higher protein intake (both < 0.01), decreased diet quality, an irregular eating pattern, and delayed meal timing (all < 0.05). Physical activity and daytime sleepiness levels did not differ between groups. Findings from this first Chilean study in healthcare shift workers support the fact that meal timing and diet quality appear as critical factors for upcoming intervention studies in this group.
我们评估了智利轮班工人的饮食模式、身体活动及日间嗜睡程度。纳入了来自智利圣地亚哥一家公立医院的50名中年成年医护人员：一组从事轮班工作（轮班工人，包括至少一个“夜班”和一个“长日班”，n = 33），另一组是按传统时间表工作的日班工人（8:00至17:00，n = 17）。评估了身体成分、身体活动、日间嗜睡程度及饮食特征（饮食构成、用餐时间和饮食质量）。尽管总能量摄入相似，但轮班工人的碳水化合物摄入量（能量百分比）较低，蛋白质摄入量较高（均P < 0.01），饮食质量下降，饮食模式不规律，用餐时间延迟（均P < 0.05）。两组之间的身体活动和日间嗜睡程度没有差异。这项智利针对医护轮班工人的首次研究结果支持了这样一个事实，即用餐时间和饮食质量似乎是该群体未来干预研究的关键因素。
