時尚雙語:習慣午睡的人易患糖尿病

Taking regular lunchtime siestas could increase the risk of developing Type 2 diabetes, according to research.

The study of 16,480 people, found those who napped were 26% more likely to get the condition than those who did not.

Several factors which may be behind the link included disrupted night-time sleep and an association between napping and reduced physical activity.

But a conference in Glasgow will hear that factors like genetics and being overweight are more significant.

The researchers will tell delegates at the Diabetes UK event that napping during the day may disrupt night-time sleep.

This could have an impact as short night-time sleep duration has been shown to be associated with an increased Type 2 diabetes risk.

Waking up from napping also activates hormones and mechanisms in the body that stop insulin working effectively, the researchers said, and this could predispose people to Type 2 diabetes-- which can develop when the insulin the body makes does not work properly.

Dr Iain Frame, director of research at Diabetes UK, said: "We already know that people who are overweight or obese, and therefore more at risk of developing Type 2 diabetes, can have problems sleeping.

"This new research could be another step towards explaining the possible link between disturbed sleep patterns and Type 2 diabetes."

"However, in terms of being major risk factors for developing Type 2 diabetes, disturbed sleep or napping are likely to remain less significant than already established risk factors such as being overweight, being over the age of 40 or having a history of diabetes in the family."

Diabetes is a serious condition that can lead to long-term complications such as heart disease, stroke, blindness, kidney failure and amputation.

The research, conducted by scientists from the University of Birmingham and from Guangzhou Hospital in China, will be presented at Diabetes UK's annual conference.

研究顯示，經常睡午覺會增加罹患二型糖尿病的危險。

在參與研究的16,480人中，那些常睡午覺的人患糖尿病的風險比不睡午覺的人高出26%。

在這一現象背後，晚上睡不好以及運動量減少，可能都是導致白天犯困的幾個因素。

但是在格拉斯哥舉行的研討會上也有人提出，基因和超重對是否患糖尿病有更大的影響。

研究人員將向出席英國糖尿病協會研討會的代表指出，午休可能會影響人們晚上的睡眠質量。

而此前已有研究證明，夜間睡眠時間短是誘發二型糖尿病的原因之一。

研究人員指出，午休過後人體會進入一個荷爾蒙分泌的活躍期，而這種反應會降低人體體內胰島素的功效，從而使人們暴露在患二型糖尿病的風險之下。一旦人體胰島素的分泌出了問題，那麼這種風險就會加劇。

英國糖尿病協會研究項目負責人伊恩·弗雷姆博士說：“先前我們就知道，超重或者肥胖的人更容易患二型糖尿病，而且這些人常常睡不好。

這項新的研究成果進一步解釋了，睡眠不規律以及睡眠質量差和二型糖尿病之間的可能存在的關聯。”

“當然，要說誘發二型糖尿病的主要因素，肥胖、年齡在40歲以上長以及家族中有糖尿病史等因素，都要勝過午休所發揮的負面作用。”

糖尿病是一種可以引發長期的臨牀綜合症的嚴重疾病，它可以導致心臟病、中風、失明、肝衰竭和截肢等嚴重後果。

這項研究由英國伯明翰大學和中國廣州一家醫院的科學家們聯合展開，研究成果將在英國年度糖尿病研討會上發佈。
