项目摘要

PROJECT SUMMARY Despite substantially declining during the past 2 decades, teenage pregnancy rates remain the highest in the United States compared to other Western countries. Being born to a teenage mother has been noted in the literature and public perceptions for many decades as a permanent source of developmental disadvantages for children. Although a strong body of literature has compared children of teen mothers to children of older mothers, less known are factors contributing to variations in developmental outcomes among children of teen mothers. As such, the relevant knowledge base is limited in informing prevention programming for healthy development among children of teen mothers. Capitalizing on unique longitudinal studies of teen mothers and their children, the proposed study aims to remedy these gaps with an explicit focus on and in-depth investigation of maternal history of substance use and exposure to adverse childhood experiences (ACEs) as two key factors promoting within-group variability in children of teen mothers. Specifically, first, we will investigate whether the timing and longitudinal trajectories of teen mothers’ substance use beyond the prenatal period affect child developmental outcomes. Second, we will examine whether maternal ACEs, which are intergenerational risk factors preceding the child’s birth, influence child development and intersect with a more proximal maternal risk factor, maternal substance use. The proposed study will leverage access to existing two-cohort Young Women and Child Development Study (YCDS) panels. Cohort 1 (C1, n = 240) spans 17 years of both the mothers’ and child’s life course. At the last wave of cohort 1data collection, children were 17 years old and mothers were 33.8 years old on average. Cohort 2 (C2, n = 255) encompasses 14 years of both mothers’ and child’s life course. At the last wave of cohort 2 data collection, children were 13.5 years old and mothers were 30.3 years old on average. This rich dataset has all the key elements to achieve the aims of the proposed study, including (a) prospective and repeated assessment of child development from infancy through adolescence in both cohorts using validated assessment packages spanning child executive functioning, language development, externalizing behaviors, and other developmental measures; (b) annual or semiannual assessments of maternal substance use from pregnancy to 17 years postpartum in C1 and 13.5 years postpartum in C2; and (c) assessment of maternal ACEs. The comprehensiveness of the datasets, with 14 to 17 waves of annual assessment, offers a novel opportunity to use longitudinal modeling strategies to identify the developmental timing and dynamic changes in maternal substance use among pregnant women, link them to child developmental outcomes, and then link those back to maternal ACEs exposure. The proposed study will maximize the use of data from both cohorts by adopting a cross-validation strategy and an integrated strategy of combining data with tests of cohort effect.

项目概要尽管在过去 20 年间有所下降，但青少年怀孕率仍然是世界上最高的。与其他西方国家相比，美国已注意到青少年母亲的出生。几十年来，文献和公众的看法一直被认为是发展不利因素的永久根源。尽管有大量文献将青少年母亲的孩子与年长母亲的孩子进行了比较。对于母亲来说，鲜为人知的是导致青少年儿童发育结果差异的因素因此，相关知识库在为健康提供预防规划方面是有限的。利用对青少年母亲的独特纵向研究和因此，拟议的研究旨在通过明确关注和深入研究来弥补这些差距对母亲物质使用史和不良童年经历 (ACE) 接触史的调查促进青少年母亲的孩子群体内差异的两个关键因素具体来说，首先，我们将。调查青少年母亲物质使用的时间和纵向轨迹是否超出产前其次，我们将检查母亲的 ACE 是否会影响儿童的发育结果。孩子出生前的代际风险因素影响儿童发展并与更多的人交叉近端孕产妇危险因素、孕产妇物质使用拟议的研究将利用现有的资料。两队列青年妇女和儿童发展研究 (YCDS) 小组 1（C1，n = 240）涵盖 17 个。在最后一批第一组数据收集中，母亲和孩子的生命历程中，孩子的年龄均为 17 岁。组 2（C2，n = 255）的平均年龄为 33.8 岁，母亲的平均年龄为 14 岁。在最后一批第二组数据收集中，儿童的年龄为 13.5 岁。母亲的平均年龄为 30.3 岁。这个丰富的数据集包含实现目标的所有关键要素。拟议的研究，包括（a）对从婴儿期到使用涵盖儿童执行功能的经过验证的评估包对两个队列的青春期进行评估，语言发展、外化行为和其他发展措施；（b）每年或每半年一次；对 C1 和 13.5 岁从怀孕到产后 17 岁的母亲物质使用情况进行评估 C2 产后；(c) 母亲 ACE 数据集的全面性评估，14 至 17 轮年度评估，提供了一个使用纵向建模策略来识别的新机会孕妇的发育时间和母体物质使用的动态变化，将它们联系起来儿童发育结果，然后将其与母亲 ACE 暴露联系起来。将通过采用交叉验证策略和集成的方法来最大限度地利用两个队列的数据将数据与队列效应测试相结合的策略。
