Nat Gene: 长期失眠会增加患心脏病风险

2012-02-06 MedSci MedSci原创

  挪威科技大学一项研究发现,长期失眠会使心脏病风险增加45%。研究小组收集了近5.3万名男女参试者的相关数据,并通过问卷调查研究了参试者的睡眠习惯。   在为期11年的跟踪调查中,研究人员发现,与没有睡眠问题的人相比,几乎每天都睡不好觉的人心脏病危险增加45%,入睡困难的人心脏病危险增加30%,睡醒后感觉身体没有恢复的人心脏病危险增加27%。   相关阅读:睡眠质量差 糖尿病风险增六倍

  《自然遗传学》杂志刊登一项最新研究发现,持续夜间辗转难眠的人罹患糖尿病和心脏病危险会增加6倍。新研究发现,仅仅3天睡眠紊乱就可能会发生糖尿病症状。

  这个研究结果有助于解释早期研究所发现的“夜班工人2型糖尿病和心脏病危险更高”的结论。

  研究涉及近2万名参试者的新研究发现,发生4种基因突变中任何一种的人,罹患糖尿病危险都更大,这表明将有望实现糖尿病个性化治疗。科学家表示,错误蛋白MT2可能干扰24小时昼夜节律与胰岛素释放的关联性,导致血糖控制失常,最终发生2型糖尿病。

  专家解释,血糖控制是人体生物钟控制的多种过程之一。这项新研究有助于进一步理解基因在生物钟影响糖尿病风险过程中的关键作用。新研究发现,MT2基因的罕见变体比过去发现的更常见的基因变体与糖尿病关联更大。
