目的是评估正常体重和肥胖女性的睡眠和用餐效率和持续时间，以及这些因素对代谢综合征(METS)变量的影响。这项研究是在70名女性中进行的，其中包括20名正常体重的女性和50名肥胖女性。测定人体测量学参数、血糖、血脂和生长激素浓度。每隔一周在午餐前和晚餐前测量血压。受试者被告知要记睡眠和喂食日记。总体而言，肥胖女性比正常体重的女性每周醒来的时间更长、次数更多，午睡时间更长。肥胖女性的睡眠效率明显较低。肥胖女性的能量摄入量较高是由于零食的差异。此外，更高的睡眠效率与夜间/早晨舒张压比率的下降相关。有趣的是，在正常体重的女性中，内脏脂肪随着醒来次数的增加而增加，而血浆Ghrelin与进餐时间呈负相关(P=0.027)。总而言之，与体重正常的女性相比，肥胖女性的睡眠效率更低，吃得更快，白天吃东西和睡觉的时间也更多。值得注意的是，睡眠效率与METS的特征有关。对肥胖的进一步干预可能包括教育患者饮食时机和更健康的睡眠卫生做法，帮助他们改变不良睡眠习惯。(C)2012爱思唯尔有限公司。保留所有权利。
The aim was to evaluate the efficiency and duration of sleep and meals in normal-weight and obese women and the impact of these factors on metabolic syndrome (MetS) variables. The study was conducted in 70 women, normal-weight women (n = 20) and obese women (n = 50). Anthropometric variables, plasma glucose, lipids and ghrelin concentrations were determined. Blood pressure measurement was performed before lunch and before dinner for a week on alternate days. Subjects were instructed to keep a sleep and feeding diary. In general, obese women displayed longer and a significantly higher number of awakenings per week than normal-weight women and a higher duration of naps. Sleep efficiency was significantly lower in obese women. The higher intake in energy in the obese women was due to snacking differences. Moreover, higher sleep efficiency was correlated with a decrease in the diastolic blood pressure evening/morning ratio. Interestingly, among normal-weight women, visceral fat increased with the number of awakenings while plasma ghrelin was inversely correlated with meal duration (P = 0.027). In conclusion, obese women had lower sleep efficiency, ate more quickly and spent more time eating and sleeping during the daytime hours than normal-weight women. Of note, sleep efficiency was associated with MetS features. Further interventions in obesity could include educating patients in food timing and in healthier sleep-hygiene practices, helping them to modify bad sleep habits. (C) 2012 Elsevier Ltd.
