Regular sleep schedules are an important part of healthy sleep habits. Although television viewing is associated with altered sleep patterns and sleep disorders among children and adolescents, the effect of television viewing on the sleep patterns of infants and toddlers is not known.
To test the hypothesis that television viewing by infants and toddlers is associated with having irregular naptime and bedtime schedules.
We used data from the National Survey of Early Childhood Health, a nationally representative, cross-sectional study of the health and health care of children 4 to 35 months of age. Our main outcome measures were whether children had irregular naptime and bedtime schedules. Our main predictor was hours of television watched on a daily basis. We performed multivariate logistic regression analyses, adjusting for a variety of factors including demographic information, measures of maternal mental health, and measures of family interactions, to test the independent association of television viewing and irregular naptime and bedtime schedules.
Data were available for 2068 children. Thirty-four percent of all children had irregular naptime schedules, and 27% had irregular bedtime schedules. Mean hours of television viewing per day were as follows: 0.9 hours/day (95% confidence interval [CI]: 0.8-1.0 hours/day) for children <12 months of age, 1.6 hours/day (95% CI: 1.4-1.8 hours/day) for children 12 to 23 months of age, and 2.3 hours/day (95% CI: 2.1-2.5 hours/day) for children 24 to 35 months of age. In our logistic regression model, the number of hours of television watched per day was associated with both an irregular naptime schedule (odds ratio: 1.09; 95% CI: 1.01-1.18) and an irregular bedtime schedule (odds ratio: 1.13; 95% CI: 1.04-1.24).
Television viewing among infants and toddlers is associated with irregular sleep schedules. More research is warranted to determine whether this association is causal.
规律的睡眠时间表是健康睡眠习惯的重要组成部分。尽管看电视与儿童和青少年睡眠模式改变及睡眠障碍有关，但看电视对婴幼儿睡眠模式的影响尚不清楚。
检验婴幼儿看电视与午睡和就寝时间不规律有关这一假设。
我们使用了来自全国幼儿健康调查的数据，这是一项针对4至35个月大儿童的健康与医疗保健的全国代表性横断面研究。我们的主要结局指标是儿童的午睡和就寝时间是否不规律。我们的主要预测因素是每天看电视的时长。我们进行了多因素逻辑回归分析，对包括人口统计学信息、母亲心理健康指标和家庭互动指标等多种因素进行了调整，以检验看电视与不规律午睡和就寝时间之间的独立关联。
共有2068名儿童的数据可供分析。所有儿童中，34%的儿童午睡时间不规律，27%的儿童就寝时间不规律。各年龄段儿童每天看电视的平均时长如下：12个月以下儿童为0.9小时/天（95%置信区间[CI]：0.8 - 1.0小时/天），12至23个月儿童为1.6小时/天（95%CI：1.4 - 1.8小时/天），24至35个月儿童为2.3小时/天（95%CI：2.1 - 2.5小时/天）。在我们的逻辑回归模型中，每天看电视的时长与不规律的午睡时间（比值比：1.09；95%CI：1.01 - 1.18）和不规律的就寝时间（比值比：1.13；95%CI：1.04 - 1.24）均相关。
婴幼儿看电视与不规律的睡眠时间表有关。有必要进行更多研究以确定这种关联是否具有因果关系。
