6~12岁儿童冲动行为与睡眠障碍相关性研究

目的：探讨儿童冲动行为与睡眠障碍的关系。方法：在长沙市5个行政辖区随机抽取1 736名6~12岁儿童，对受试儿童的家长进行睡眠状况和Barratt冲动量表问卷调查。结果：1 736例儿童中睡眠障碍总发生率为31.9%，男性为35.4%，较女性的28.3%明显增高（P＜0.01）。睡眠障碍组注意因子、运动因子、缺少计划因子得分及冲动量表总分均明显高于非睡眠障碍组（P＜0.01）；睡眠障碍组白天嗜睡率为35.9%，较非睡眠障碍组的24.7%增高显著（P＜0.01）。注意因子、运动因子及缺少计划因子得分随着睡眠障碍评分等级的升高而呈现上升趋势，睡眠障碍评分升至5级时，各因子得分均达最高水平。经常打鼾组各因子得分均高于从不打鼾组及偶尔打鼾组（P＜0.01）。结论：儿童冲动行为与睡眠障碍相关，对临床表现较高冲动水平的儿童，有必要关注其睡眠状况。［中国当代儿科杂志，2009，11（4）：310-312］

Relationship between impulsivity and sleep disorders in children aged 6 to 12 years

ObjectiveTo study the relationship between impulsivity and sleep disorders in children.MethodsA total of 1 736 children at ages of 6 to 12 years were randomly sampled from five districts of Changsha.Their parents completed the questionnaires about children′s sleep conditions and behaviors(using Barratt Impulsiveness Scale 11th version).ResultsFive hundred and fifty-four children(31.9%) had sleep disorders.The incidence of sleep disorders in boys was significantly higher than that in girls(35.4% vs 28.3%;P<0.01).The scores of attentional,motor,and non-planning impulsiveness factors as well as the total score of Barratt Impulsiveness Scale in children with sleep disorders were significantly higher than those in children without(P<0.01).The incidence of daytime sleepiness(35.9%) in children with sleep disorders was significantly higher than that in children without(24.7%;P<0.01).The scores of attentional,motor and non-planning impulsiveness factors increased with the grade of sleep disorders,and reached a peak at the fifth grade.The children with frequent sleep snoring showed higher scores of above three impulsiveness factors than children without sleep snoring or having rare snoring(P<0.01).ConclusionsSleep disorders are associated with impulsivity in children.It is thus essential to pay close attentions to children′s sleep for children with relatively high impulsiveness.
