上下文在学龄儿童、青少年和成人中，看电视与肥胖有关，但这种关系尚未在学龄前儿童中进行评估。描述一个多种族、低收入学龄前儿童群体的电视/视频观看习惯，并确定电视/视频观看是否与他们的肥胖有关。对父母/监护人进行儿童身高和体重测量的横断面调查。设置和参与者。2761名有儿童的成人，每天每增加一小时观看电视/视频，第1至第85百分位数为1.06（95%置信区间[CI]：1.004-1.11），与儿童年龄、儿童性别、父母教育程度和种族/民族无关。近40%的孩子在卧室里有电视机;他们更有可能超重，并且比卧室里没有电视的孩子花更多的时间（每周4.6小时）看电视/视频。在多元逻辑回归中，在对儿童年龄、儿童性别、儿童每周看电视/视频时间、母亲BMI、母亲教育程度和种族/民族进行统计调整后，卧室有电视的儿童与没有电视的儿童的BMI >第85百分位数的比值比为1.31（95%CI：1.01-1.69）。这项研究将看电视和超重风险之间的联系扩展到了更年轻的学龄前儿童。孩子卧室里的电视是超重风险增加的一个更强的标志。因为大多数孩子在2岁之前就看电视了，所以限制孩子看电视/视频和把电视放在孩子卧室外面的教育工作需要在那之前开始。
Context. Television (TV) viewing is associated with obesity among school-aged children, adolescents, and adults, but this relationship has not been evaluated in preschool-aged children.Objective. To describe the TV/video viewing habits of a multiethnic, low-income preschool population of children and to determine whether TV/video viewing is related to their adiposity.Design. Cross-sectional survey of parents/guardians with measurements of children's height and weight.Setting and Participants. Two thousand seven hundred sixty-one adults with children, 1 through 85th percentile was 1.06 (95% confidence interval [CI]: 1.004-1.11) for each additional hour per day of TV/video viewed, independent of child age, child sex, parental educational attainment, and race/ethnicity. Almost 40% of children had a TV set in their bedroom; they were more likely to be overweight and spent more time (4.6 hours per week) watching TV/video than children without a TV in their bedroom. In multiple logistic regression, the odds ratio of having a BMI >85th percentile was 1.31 (95% CI: 1.01-1.69) among those with a TV in their bedroom versus those without a TV, after statistical adjustment for child age, child sex, child TV/video viewing hours per week, maternal BMI, maternal education, and race/ethnicity.Conclusions. This study extends the association between TV viewing and risk of being overweight to younger, preschool-aged children. A TV in the child's bedroom is an even stronger marker of increased risk of being overweight. Because most children watch TV by age 2, educational efforts about limiting child TV/video viewing and keeping the TV out of the child's bedroom need to begin before then.
