Obesity:睡得少会发胖的原因:降低静息代谢率!

背景:睡眠时间缩短是导致民众体重增加的重要危险因素,尤其是对男性和非洲裔美国人而言更是如此。热量的摄入增加则是其基础,但尚不清楚这个过程中是否伴随有能量消耗的减少。当前的研究对睡眠限制和恢复睡眠时间对非洲裔美国人和白人能量消耗的影响。


方式:研究人员选取了一些健康成人进行了实验室研究。经历两个晚上的基础睡眠后,受试者被随机分配到两个组中,实验组受试者(n = 36)每晚睡4 h,连续5晚,之后可获得一个连续12小时的安眠;对照组受试者(n=11)每晚睡10 h。且受试者要求晚上空腹,然后研究人员于每日早上检测受试者的静息代谢率和呼吸商(RQ)。 

结果:研究人员发现,限制睡眠后恢复睡眠,则民众的静息代谢率(在民众能量消耗中所占比重最大)降低(-2.6%,P=0.032)。对照组民众的静息代谢率无明显变化。无论睡眠时间长短,相对于白种人(n = 14)而言,非裔美国人(n = 22)每日的热量摄入相似,但静息代谢率较低(P =0.043)、呼吸商更高(P =0.013)。 

结论:睡眠不足导致民众早上的静息代谢率下降,这表明睡眠不足会导致民众的新陈代谢发生变化。

先前有研究表明,睡眠持续时间与2型糖尿病风险呈“U”形关系,但是关于睡眠时间的变化与该疾病的关系的研究目前还没有。研究者进行了一项研究,探究睡眠持续时间的长期改变、饮食的变化、运动和体重与糖尿病发生风险间联系。该队列研究纳入了59031名年龄在55-83岁没有糖尿病的女性。参与者自我报道的1986年和2000年睡眠持续时间的变化差异很大。研究者每2-4年采集参与者的因素、运动以及其他相关因素信息。
