研究发现,在过去四年中,如果平均每天的咖啡摄入量增加了一杯半,其Ⅱ型糖尿病的发病率则会减少11%,这无疑降低了Ⅱ型糖尿病的发病几率。咖啡和茶摄入量的增加与Ⅱ型糖尿病的发病率减少有关,但人们对这种联系内在的机理却知之甚少,直到现在,这个谜团终于被解开了。

作者就四年中咖啡和茶摄入量的变化与随后四年中Ⅱ型糖尿病发病率之间的联系进行了调查。

最近发布在欧洲糖尿病研究协会《糖尿病学》(Diabetologia)杂志上的研究称,在一个为期四年的时间段中,如果平均每天的咖啡摄入量增加了一杯半(大约360毫升),其Ⅱ型糖尿病的发病率则会减少11%.哈佛大学公共卫生学院的 Frank Hu博士、Shilpa Bhupathiraju博士及其同事领导了这项研究。

咖啡和茶水摄入量的增加与Ⅱ型糖尿病的发病率减少有关,但人们对这种联系内在的机理却知之甚少。作者就四年中咖啡和茶摄入量的变化与随后四年中Ⅱ型糖尿病发病率之间的联系进行了调查。

作者在分析过程中采用的观察数据来自美国三大前瞻性研究:护士健康研究(NHS)(1986-2006,对象为30到55岁的女性护士)、NHS II(1991-2007,对象为25到42岁的年轻女性护士)以及健康专业随访研究(HPFS)(1986-2007,对象为40到75岁的男性专业人员)。在20年中,研究人员每隔两到四年就会对这些对象的饮食、生活方式、药物环境以及其他慢性病情况的详细信息进行收集。

通过这些反复的测量和长期的随访,作者能够分析出人们在4年中对咖啡和茶摄入量的变化与接下来四年中II型糖尿病的发病率之间的关系。同时他们还调查了含咖啡因和不含咖啡因的咖啡是否对糖尿病发病率有不同的影响。通过四年一次的食物摄入频率调查问卷,研究者们对饮食数据进行了评估。而随后的补充问卷中,受访者们被要求填写自己是否患有II型糖尿病。最终的分析过程综合了包括NHS中48464名女性、NHS II中47510名女性以及HPFS中27759名男性的调查数据。

作者记录了7269个II型糖尿病案例,发现在一个为期4年的时间段内,咖啡摄入量有所增加的参与者(平均每天增加摄入1杯或以上,中值增加1.69杯/天),他们在随后四年中的II型糖尿病发病率比咖啡摄入量没有变化的参与者要少11%.咖啡摄入量有所减少的参与者(平均每天减少摄入一杯或以上,中值减少2杯/天),他们患II型糖尿病的概率会增加17%.而茶水的摄入量则与II型糖尿病发病率没有联系。

咖啡摄入量最高,并能够保持这一状态的人--由于他们每天会摄入3杯甚至更多的咖啡,故被称为“高稳定度消费者”--其II型糖尿病患病率最低,比“低稳定度消费者”(每天摄入一杯或更少的咖啡)要低37%.

作者称,II型糖尿病发病率的增加与咖啡摄入量的减少有关,这代表了患病风险会在咖啡这一因素的影响下会有所变化,但也许这种联系是受到了某种逆因果事件的潜在影响:患有疾病的患者(例如高血压、胆固醇、心血管疾病或者癌症)往往会伴随患II型糖尿病的风险,而他们在服用药物后会减少对咖啡的摄入。然而,即使在随访中排除患有心血管疾病或癌症的案例,结果也不会有太大改变。

虽然无咖啡因咖啡的基本摄入量与II型糖尿病发病率的降低有关,但其摄入量的改变并不会影响此疾病的发病率。至于茶水的摄入,作者称:“我们并没有发现在四年中茶水摄入量的改变影响II型糖尿病发病率的证据。这也许是由于我们的受访者在一个为期4年的时间段中对茶水摄入量的变化不大,因此无法完全统计出它们两者之间的关联。同时受访者总体对茶水的摄入量较低也是一个原因。”

作者称:“在这3大调查团队中,研究者们对超过160万参与者进行了多年随访,我们观察到,在一个为期4年的时间段内,咖啡的摄入量增加,同时茶水的摄入量没有增加的人,他们在接下来4年中具有更低的II型糖尿病发病率。咖啡摄入量的减少与更高II型糖尿病发病率有关。同时我们还发现,含咖啡因咖啡摄入量的改变会影响II型糖尿病发病率,而不含咖啡因的咖啡摄入量的改变则不会对其产生影响。并且,这与最初的咖啡摄入量,以及四年中其他饮食和生活方式上的改变无关。”他们补充道:“咖啡食用习惯的改变会在一个相对较短的时间内影响糖尿病发病率。我们的发现证实了,较高的咖啡摄入量与较低的II型糖尿病发病率有关,同时我们还提出了新颖的证据证明,咖啡食用习惯的改变与糖尿病发病率有关。”
