To describe the time children spend watching television (TV) and to assess associations between TV viewing time, the family environment and weight status.
Parents reported the amount of time children watched TV/video both for 'the previous school day' and 'usually' and described aspects of the family environment influencing TV access as part of a large cross-sectional study in the Barwon South-western region of Victoria, Australia. Child weight status was based on measured height and weight. All data were collected in 2003/2004.
A total of 1926 children aged 4-12 years participated. Parent-reported mean +/- SE TV time for the previous school day was 83 +/- 1.5 min. Children who lived in a family with tight rules governing TV viewing time (22%), or who never watched TV during dinner (33%), or had only one TV in the household (23%) or had no TV in their bedroom (81%) had significantly less TV time than their counterparts. Overweight or obese children had more TV time than healthy weight children 88 +/- 2.9 versus 82 +/- 1.7 min per day (P=0.04). They were also more likely to live in a household where children had a TV in their bedroom than healthy weight children (25% vs. 17%, P<0.001).
Strategies to reduce TV time should be included as part of broader strategies to prevent childhood obesity. They should include messages to parents about not having a TV in children's bedrooms, encouraging family rules restricting TV viewing, and not having the TV on during dinner.
描述儿童看电视的时间，并评估看电视时间、家庭环境与体重状况之间的关联。
在澳大利亚维多利亚州西南地区的一项大型横断面研究中，家长报告了孩子在“前一个上学日”和“通常情况下”看电视/视频的时间，并描述了影响看电视机会的家庭环境方面。儿童的体重状况基于测量的身高和体重。所有数据均于2003/2004年收集。
共有1926名4至12岁的儿童参与。家长报告的前一个上学日的平均电视观看时间为83±1.5分钟。生活在有严格电视观看时间规定家庭中的儿童（22%）、晚餐时从不看电视的儿童（33%）、家中只有一台电视的儿童（23%）或卧室里没有电视的儿童（81%）看电视的时间明显少于其他儿童。超重或肥胖儿童比体重正常的儿童看电视时间更长，分别为每天88±2.9分钟和82±1.7分钟（P=0.04）。与体重正常的儿童相比，他们也更有可能生活在孩子卧室里有电视的家庭中（25%对17%，P<0.001）。
减少看电视时间的策略应作为预防儿童肥胖的更广泛策略的一部分。这些策略应包括向家长传达不在孩子卧室放置电视的信息，鼓励制定限制看电视的家庭规则，以及晚餐时不开电视。
