电视暴露和睡眠问题对18月龄儿童智能发育的影响

Influence of television exposure and sleep problems on children intellectual development at 18 months

目的探讨电视暴露和睡眠问题与18月龄儿童智能发育的关联。方法以2013年7月-2014年4月在马鞍山市妇幼保健院儿童保健门诊进行常规体检的18月龄儿童作为研究对象。收集相关的人口统计学信息、屏幕暴露和睡眠情况等。采用＂0~6岁儿童智能筛查测验量表＂（DST）对儿童的智能进行评估。共获得有效问卷1 647份,其中男童843人、女童804人。使用χ2检验和Logistic回归模型对数据进行分析。结果调整性别、独生子女、父母年龄、父母文化程度、工作性质、家庭月收入,同时将电视暴露、睡眠问题、入睡有规律纳入回归方程分析,结果显示电视暴露≥60min和睡眠问题均能独立增加儿童边缘智力及智力低下发生的风险（OR=1.89,95%CI：1.11~3.23;OR=1.46.95%CI：1.03~2.07）。结论长时间的电视暴露和睡眠问题对儿童智力发育有消极的影响。
