To examine the extent to which infant television viewing is associated with language and visual motor skills at 3 years of age.
We studied 872 children who were participants in Project Viva, a prospective cohort. The design used was a longitudinal survey, and the setting was a multisite group practice in Massachusetts. At 6 months, 1 year, and 2 years, mothers reported the number of hours their children watched television in a 24-hour period, from which we derived a weighted average of daily television viewing. We used multivariable regression analyses to predict the independent associations of television viewing between birth and 2 years with Peabody Picture Vocabulary Test III and Wide-Range Assessment of Visual Motor Abilities scores at 3 years of age.
Mean daily television viewing in infancy (birth to 2 years) was 1.2 (SD: 0.9) hours, less than has been found in other studies of this age group. Mean Peabody Picture Vocabulary Test III score at age 3 was 104.8 (SD: 14.2); mean standardized total Wide-Range Assessment of Visual Motor Abilities score at age 3 was 102.6 (SD: 11.2). After adjusting for maternal age, income, education, Peabody Picture Vocabulary Test III score, marital status, and parity, and child's age, gender, birth weight for gestational age, breastfeeding duration, race/ethnicity, primary language, and average daily sleep duration, we found that each additional hour of television viewing in infancy was not associated with Peabody Picture Vocabulary Test III or total standardized Wide-Range Assessment of Visual Motor Abilities scores at age 3.
Television viewing in infancy does not seem to be associated with language or visual motor skills at 3 years of age.
探讨婴儿期看电视与3岁时语言和视觉运动技能之间的关联程度。
我们研究了参与“活力计划”这一前瞻性队列研究的872名儿童。采用的设计是纵向调查，研究地点为马萨诸塞州的一个多地点团体诊所。在6个月、1岁和2岁时，母亲报告孩子在24小时内看电视的时长，据此我们得出每日看电视时长的加权平均值。我们使用多变量回归分析来预测出生至2岁期间看电视与3岁时皮博迪图片词汇测验第三版（PPVT-III）分数以及视觉运动能力广泛评估（WRVMA）分数之间的独立关联。
婴儿期（出生至2岁）平均每日看电视时长为1.2（标准差：0.9）小时，低于该年龄组其他研究中的发现。3岁时皮博迪图片词汇测验第三版的平均分数为104.8（标准差：14.2）；3岁时视觉运动能力广泛评估标准化总分的平均分数为102.6（标准差：11.2）。在对母亲年龄、收入、教育程度、皮博迪图片词汇测验第三版分数、婚姻状况、生育次数，以及孩子的年龄、性别、孕龄出生体重、母乳喂养时长、种族/族裔、主要语言和平均每日睡眠时间进行调整后，我们发现婴儿期每多看一小时电视与3岁时皮博迪图片词汇测验第三版分数或视觉运动能力广泛评估标准化总分之间并无关联。
婴儿期看电视似乎与3岁时的语言或视觉运动技能无关。
