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.

研究显示，经常睡午觉会增加罹患二型糖尿病的危险。

在参与研究的16,480人中，那些常睡午觉的人患糖尿病的风险比不睡午觉的人高出26%。

在这一现象背后，晚上睡不好以及运动量减少，可能都是导致白天犯困的几个因素。

但是在格拉斯哥举行的研讨会上也有人提出，基因和超重对是否患糖尿病有更大的影响。

研究人员将向出席英国糖尿病协会研讨会的代表指出，午休可能会影响人们晚上的睡眠质量。

而此前已有研究证明，夜间睡眠时间短是诱发二型糖尿病的原因之一。

研究人员指出，午休过后人体会进入一个荷尔蒙分泌的活跃期，而这种反应会降低人体体内胰岛素的功效，从而使人们暴露在患二型糖尿病的风险之下。一旦人体胰岛素的分泌出了问题，那么这种风险就会加剧。

英国糖尿病协会研究项目负责人伊恩·弗雷姆博士说：“先前我们就知道，超重或者肥胖的人更容易患二型糖尿病，而且这些人常常睡不好。

这项新的研究成果进一步解释了，睡眠不规律以及睡眠质量差和二型糖尿病之间的可能存在的关联。”

“当然，要说诱发二型糖尿病的主要因素，肥胖、年龄在40岁以上长以及家族中有糖尿病史等因素，都要胜过午休所发挥的负面作用。”

糖尿病是一种可以引发长期的临床综合症的严重疾病，它可以导致心脏病、中风、失明、肝衰竭和截肢等严重后果。

这项研究由英国伯明翰大学和中国广州一家医院的科学家们联合展开，研究成果将在英国年度糖尿病研讨会上发布。
