本研究的目的是在考虑午睡时间(长：30 分钟，短：≤30 分钟)的情况下，确定午睡和不午睡与肥胖的关系，并测试午睡特征和/或生活方式因素是否中介午睡与肥胖和代谢综合征(METS)的关联。方法这是一项横断面研究，来自地中海人群(肥胖、营养遗传学、时间选择和地中海[OnTime]研究)，他们有机会午睡，因为它具有文化根深蒂固。与不午睡组相比，午睡时间长与体重指数、腰围、空腹血糖、收缩压和舒张压的值高相关，并且与甲亢组的患病率高(41%；p= 0.015)。相反，短时间午睡组的收缩压升高的概率(21%；p= 0.044)低于不午睡组。每天吸烟的数量越多，午睡时间越长，体重指数越高(12%，吸烟导致的关联百分比；p<； 0.05)。同样，夜间睡眠和进食时间表的延迟以及午餐(午睡前的一餐)较高的能量摄入量分别将较高的体重指数和较长的午睡时间之间的关联中介了8%、4%和5%(均为 0.05)。在床上打盹(与沙发/扶手椅相比)显示出在长午睡和较高收缩压之间的中介作用(6%；p= 0.055)。结论午睡时间与肥胖/代谢综合征有关。夜间睡眠和进食的时间、午餐的能量摄入量、吸烟和午睡地点调节了这种联系。
ObjectiveThe aim of this study was to determine the association between siestas/no siestas and obesity, considering siesta duration (long: >30 minutes, short: ≤30 minutes), and test whether siesta traits and/or lifestyle factors mediate the association of siestas with obesity and metabolic syndrome (MetS).MethodsThis was a cross‐sectional study of 3275 adults from a Mediterranean population (the Obesity, Nutrigenetics, TIming, and MEditerranean [ONTIME] study) who had the opportunity of taking siestas because it is culturally embedded.ResultsThirty‐five percent of participants usually took siestas (16% long siestas). Compared with the no‐siesta group, long siestas were associated with higher values of BMI, waist circumference, fasting glucose, systolic blood pressure, and diastolic blood pressure, as well as with a higher prevalence of MetS (41%;p= 0.015). In contrast, the probability of having elevated SBP was lower in the short‐siesta group (21%;p= 0.044) than in the no‐siesta group. Smoking a higher number of cigarettes per day mediated the association of long siestas with higher BMI (by 12%, percentage of association mediated by smoking;p< 0.05). Similarly, delays in nighttime sleep and eating schedules and higher energy intake at lunch (the meal preceding siestas) mediated the association between higher BMI and long siestas by 8%, 4%, and 5% (allp< 0.05). Napping in bed (vs. sofa/armchair) showed a trend to mediate the association between long siestas and higher SBP (by 6%;p= 0.055).ConclusionsSiesta duration is relevant in obesity/MetS. Timing of nighttime sleep and eating, energy intake at lunch, cigarette smoking, and siesta location mediated this association.
