Objective.横断面研究表明，看电视可能与儿童注意力持续时间的减少有关。然而，早期电视暴露和随后的注意力问题的纵向数据一直缺乏。本研究的目的是检验早期接触电视（1岁和3岁）与7岁时注意力问题相关的假设。我们使用了全国青年纵向调查，这是一个具有代表性的纵向数据集。我们的主要结果是在7岁时确定所有参与者的行为问题指数的多动子量表。大于或等于平均值以上1.2个标准差的儿童被归类为有注意力问题。我们的主要预测因素是1岁和3岁时每天看电视的时间。有1278名1岁儿童和1345名3岁儿童的数据可用。10%的儿童在7岁时有注意力问题。在逻辑回归模型中，1岁和3岁时每天看电视的时间分别与7岁时的注意力问题相关（1.09 [1.03 - 1.15]和1.09 [1.02 - 1.16]）。早期接触电视与7岁时的注意力问题有关。限制儿童早期看电视的努力可能是必要的，需要进行更多的研究。
Objective. Cross-sectional research has suggested that television viewing may be associated with decreased attention spans in children. However, longitudinal data of early television exposure and subsequent attentional problems have been lacking. The objective of this study was to test the hypothesis that early television exposure ( at ages 1 and 3) is associated with attentional problems at age 7.Methods. We used the National Longitudinal Survey of Youth, a representative longitudinal data set. Our main outcome was the hyperactivity subscale of the Behavioral Problems Index determined on all participants at age 7. Children who were greater than or equal to 1.2 standard deviations above the mean were classified as having attentional problems. Our main predictor was hours of television watched daily at ages 1 and 3 years.Results. Data were available for 1278 children at age 1 and 1345 children at age 3. Ten percent of children had attentional problems at age 7. In a logistic regression model, hours of television viewed per day at both ages 1 and 3 was associated with attentional problems at age 7 (1.09 [1.03 - 1.15] and 1.09 [1.02 - 1.16]), respectively.Conclusions. Early television exposure is associated with attentional problems at age 7. Efforts to limit television viewing in early childhood may be warranted, and additional research is needed.
