Many young children have televisions in their bedrooms, which may influence the relationship between parental estimate and objective measures of child television usage/week. Parental estimates of child television time of eighty 4-7 year old children (6.0 +/- 1.2 years) at the 75th BMI percentile or greater (90.8 +/- 6.8 BMI percentile) were compared to an objective measure of television time obtained from TV Allowance devices attached to every television in the home over a three week period. Results showed that parents overestimate their child's television time compared to an objective measure when no television is present in the bedroom by 4 hours/week (25.4 +/- 11.5 vs. 21.4 +/- 9.1) in comparison to underestimating television time by over 3 hours/week (26.5 +/- 17.2 vs. 29.8 +/- 14.4) when the child has a television in their bedroom (p = 0.02). Children with a television in their bedroom spend more objectively measured hours in television time than children without a television in their bedroom (29.8 +/- 14.2 versus 21.4 +/- 9.1, p = 0.003). Research on child television watching should take into account television watching in bedrooms, since it may not be adequately assessed by parental estimates.
许多幼儿卧室里都有电视，这可能会影响父母估计的孩子每周看电视时间与客观测量结果之间的关系。研究人员比较了80名4至7岁儿童（平均年龄6.0±1.2岁）的父母对孩子看电视时间的估计，这些孩子的BMI百分位数在第75百分位及以上（平均BMI为90.8±6.8），并将其与通过安装在家庭每台电视上的电视使用监测设备在三周内客观测量得到的看电视时间进行了对比。结果显示，当孩子卧室没有电视时，与客观测量结果相比，父母高估了孩子每周看电视时间4小时（分别为25.4±11.5小时和21.4±9.1小时）；而当孩子卧室有电视时，父母低估了孩子每周看电视时间超过3小时（分别为26.5±17.2小时和29.8±14.4小时）（p = 0.02）。卧室里有电视的孩子客观测量的看电视时间比卧室里没有电视的孩子更多（分别为29.8±14.2小时和21.4±9.1小时，p = 0.003）。关于儿童看电视的研究应考虑在卧室里看电视的情况，因为父母的估计可能无法充分评估这一点。
