最近一项针对加拿大魁北克省儿童的研究发现,当父母都存在梦游行为,超过60%的儿童也会出现梦游行为。
 
梦游是一种常见的儿童睡眠紊乱,一般随着年龄增大,梦游行为逐渐消失,但也有可能到成年阶段仍然存在。睡惊症是另一种儿童睡眠障碍,也叫夜惊,是指小儿在睡眠中突然喊叫,坐起,惊叫,两眼直视或紧闭,手足乱动,或从床上跳下,表情紧张,气急,颤抖,意识模糊,不认识父母,数分钟后安静下来,继续入睡。这两种睡眠紊乱具有一些类似特征,都主要来源于慢波睡眠。
 
研究人员对1940名儿童的睡眠数据进行了分析,以调查问卷的形式对儿童梦游和睡惊症两种睡眠紊乱行为进行了评估,同时还以口头问询的形式对父母的梦游情况进行了调查。
 
结果表明,年龄在1岁半到13岁的儿童中,大约56.2%的儿童存在睡惊症,并且1岁半左右的儿童睡惊症更加普遍,随着年龄增加,这种睡眠紊乱行为的出现随之减少。
 
在全部调查儿童中,存在梦游行为的儿童大约有29.1%,学前儿童中存在梦游行为的较少,而随年龄增长,梦游行为的出现也逐渐增加。同时,研究人员还发现儿童梦游行为与父母的梦游史有关,父母中有一人存在梦游行为,其孩子发生梦游的概率是父母无梦游史的儿童的三倍,而父母都存在梦游行为的儿童,其发生梦游行为的概率是父母无梦游史的儿童的七倍。
 
这项研究表明基因或对儿童梦游行为具有重要影响,并且这种影响可能是通过参与慢波睡眠形成以及影响睡眠深度的基因多态性实现的。
