Fragile Families and Child Wellbeing in Adolesence

描述(由申请人提供)：脆弱家庭和儿童福祉研究(FFS)是一项具有全国代表性的出生队列研究，研究对象是1998至2000年间在美国大城市(20万或更多人口)出生的大约4900名儿童。这项研究包括：(1)出生时对父母的访谈，以及孩子1、3、5和9岁时的再次访谈；(2)母亲和儿童出生时的医疗记录；(3)儿童3、5和9岁时对儿童及其家庭环境的家庭评估；(4)9岁时对儿童的访谈；(5)儿童3、5和9岁时对教师的采访；(6)儿童9岁时母亲和儿童的DNA样本。这项研究还包括深入的研究，在孩子出生后的头四年里，对大约75对夫妇进行了纵向采访。这项研究设计要求对未婚父母的生育进行大量超额抽样，因此，这些数据是研究少数民族和经济困难人群之间健康差距的宝贵资源。到目前为止，已有1300多名研究人员下载了公共使用数据，谷歌学者使用FFS数据列出了730篇学术文章、论文、书籍和摘要，这些文章、论文、书籍和摘要涵盖了NICHD当前拨款所涵盖的2006-2011年期间。我们寻求资金，以便在儿童15岁时对母亲和儿童进行另一轮访谈。我们的具体目标是：更新有关儿童健康和发育的信息，并收集有关儿童15岁时的健康和健康风险行为、学校表现以及反社会和亲社会行为的新数据。更新儿童15岁时的背景因素信息，包括家庭、社区、学校和同龄人，包括自上次访谈以来的家庭经历回顾数据。 收集3600名15岁儿童的唾液样本，用于未来的甲基化分析。约3600名母亲和3100名儿童将接受电话采访。这些电话采访时间为母亲55分钟，儿童45分钟。500名青少年将接受约1小时的面谈。

DESCRIPTION (provided by applicant): The Fragile Families and Child Wellbeing Study (FFS) is a nationally representative, birth cohort study of approximately 4900 children born in large US cities (populations of 200,000 or more) between 1998 and 2000. The study includes: (1) interviews with mothers and fathers at birth and again when children are 1, 3, 5 and 9 years old, (2) medical records for a subset of mothers and children at birth, (3) in-home assessments of children and their home environments when children are 3, 5, and 9 years old, (4) interviews with children at age 9, (5) interviews with teachers when children are 3, 5, and 9 years old and (6) DNA samples from mothers and children when children are age 9. The study also includes in-depth, longitudinal interviews with a subset of approximately 75 couples during the first four years after the child's birth. The study design called for a large oversample of births to unmarried parents, and thus the data are a valuable resource for studying health disparities among minority and economically disadvantaged populations. To date, more than 1300 researchers have downloaded the public use data, and Google Scholar lists 730 scholarly articles, theses, books, and abstracts using the FFS data for the period covered by the current NICHD grant, 2006-2011. We seek funding to conduct another round of interviews with mothers and children when children are 15 years old. Our specific aims are to: " Update information on children's health and development and collect new data on health and health risk behavior, school performance, and anti- and pro-social behavior when children are age 15 " Update information on contextual factors, including families, neighborhoods, schools and peers, when children are age 15, including retrospective data on family experiences since the last interview " Collect saliva samples from 3,600 children at age 15 to be used for future methylation analysis Approximately 3600 mothers and 3100 children will be interviewed via phone. These phone interviews will be 55 minutes for mothers and 45 minutes for children. Five hundred adolescents will be interviewed in person for approximately 1 hour.
