To determine the television-, DVD-, and video-viewing habits of children younger than 2 years.
A telephone survey of 1009 parents of children aged 2 to 24 months.
Parents in Minnesota and Washington state were surveyed.
A random sample of parents of children born in the previous 2 years was drawn from birth certificate records. Households in which English was not spoken were excluded, as were children with major disabilities.
The amount of regular television and DVD/video viewing by content, reasons for viewing, and frequency of parent-child coviewing.
By 3 months of age, about 40% of children regularly watched television, DVDs, or videos. By 24 months, this proportion rose to 90%. The median age at which regular media exposure was introduced was 9 months. Among those who watched, the average viewing time per day rose from 1 hour per day for children younger than 12 months to more than 1.5 hours per day by 24 months. Parents watched with their children more than half of the time. Parents gave education, entertainment, and babysitting as major reasons for media exposure in their children younger than 2 years.
Parents should be urged to make educated choices about their children's media exposure. Parental hopes for the educational potential of television can be supported by encouraging those parents who are already allowing screen time to watch with their children.
确定2岁以下儿童观看电视、DVD及视频的习惯。
对1009名年龄在2至24个月儿童的家长进行电话调查。
对明尼苏达州和华盛顿州的家长进行调查。
从出生证明记录中随机抽取过去2年出生儿童的家长作为样本。排除不讲英语的家庭以及有严重残疾的儿童。
按内容统计的常规电视及DVD/视频观看量、观看原因以及亲子共同观看的频率。
到3个月大时,约40%的儿童经常观看电视、DVD或视频。到24个月时,这一比例升至90%。开始进行常规媒体接触的中位年龄为9个月。在观看的儿童中,每天的平均观看时间从12个月以下儿童的每天1小时增加到24个月时的每天超过1.5小时。家长与孩子一起观看的时间超过一半。家长将教育、娱乐和照看孩子作为让2岁以下儿童接触媒体的主要原因。
应敦促家长对孩子接触媒体做出明智选择。对于那些已经允许孩子看屏幕的家长,鼓励他们与孩子一起观看,可以支持家长对电视教育潜力的期望。
