DESCRIPTION (provided by applicant): The prevalence of obesity in American youth has reached alarming levels. The proportion of obesity among adolescents has tripled in the past three decades with approximately 15% of 6-19 year-olds qualifying as obese. Many believe that time spent with electronic media is at least partly to blame. It is true that children spend more time using electronic media than in any other single free-time activity except for sleep. However, though there is some evidence linking media use to childhood obesity, a deeper understanding of their developmental connections between them has been hindered by a distinct dearth of longitudinal studies which include developmental and contextual information in explanatory models. The objective of this proposal is to elucidate these connections from childhood through adolescence using longitudinal data from a representative US sample of approximately 3,500 children spanning ages 0-18 from the Panel Study of Income Dynamics (PSID) Child Development Supplement (CDS). We draw upon an ecological framework to deepen existing knowledge of the developmental links between media use and childhood obesity. The richness of the CDS data render them uniquely suited for this purpose and allow for considerably stronger and more comprehensive analyses compared to existing data. Three waves of CDS data will be used, including data from 1997 (ages 0-12), 2002 (ages 5-18), and 2007 (ages 10-18). The CDS panel data represents an extraordinary opportunity to further knowledge regarding the nature of the relationship between children's media use and the development of obesity. Despite over 30 years worth of research efforts aimed at understanding childhood obesity, we know surprisingly little about role of electronic media. Developmental connections have gone unexamined, moderating influences have not been identified, and mediating processes have gone untested. It seems safe to say that technology is here to stay, and is virtually guaranteed to play an ever increasing role in our daily lives. Thus, a thorough understanding of the nature of its impact on the development of obesity is a vital component of the public health agenda in the U.S.

描述（由申请人提供）：美国青少年的肥胖患病率已达到惊人的水平。过去三十年里，青少年肥胖的比例增加了两倍，6-19 岁青少年中约有 15% 属于肥胖。许多人认为，花在电子媒体上的时间至少是部分原因。确实，孩子们使用电子媒体的时间比除睡眠之外的任何其他单一空闲时间活动都多。然而，尽管有一些证据将媒体使用与儿童肥胖联系起来，但由于缺乏纵向研究（其中包括解释模型中的发育和情境信息），对它们之间的发育联系的更深入理解受到阻碍。该提案的目的是利用来自收入动态小组研究 (PSID) 儿童发展补充资料 (CDS) 的美国约 3,500 名 0-18 岁儿童的代表性样本的纵向数据，阐明从童年到青春期的这些联系。我们利用生态框架来加深对媒体使用与儿童肥胖之间发展联系的现有了解。 CDS 数据的丰富性使其特别适合此目的，并且与现有数据相比，可以进行更强大、更全面的分析。将使用三波 CDS 数据，包括 1997 年（0-12 岁）、2002 年（5-18 岁）和 2007 年（10-18 岁）的数据。 CDS 小组数据为进一步了解儿童媒体使用与肥胖发展之间关系的本质提供了绝佳的机会。尽管我们为了解儿童肥胖问题进行了 30 多年的研究工作，但令人惊讶的是，我们对电子媒体的作用知之甚少。发展联系尚未得到检验，调节影响尚未确定，中介过程也未经检验。可以肯定地说，技术将继续存在，并且几乎肯定会在我们的日常生活中发挥越来越重要的作用。因此，彻底了解其对肥胖发展影响的本质是美国公共卫生议程的重要组成部分。
