UNINTENDED PREGNANCY EFFECTS ON CHILD DEVELOPMENT

描述：意外怀孕与产前检查不足有关 护理、低出生体重以及婴儿死亡风险增加、儿童 虐待和发育缺陷。意外事件之间的关联 怀孕和儿童发育专家建议增加 努力减少意外怀孕。然而，有证据表明 意外怀孕会导致不良分娩和发育结局 出人意料的稀疏。 这项拟议的研究将从经验上调查 意外怀孕与儿童健康和发育，以及不良父母 影响儿童健康和发育的行为。拟议的研究 在几个方面改进了以前的研究。首先，调查人员使用 两个相辅相成的数据来源：NLS和NMIHS。的两个来源 数据拓宽了可能被分析的结果的数量，并使我们能够 测试拟议研究结果的稳健性。第二， 调查人员利用兄弟姐妹和表亲的信息来控制 未观察到的与儿童结局和非预期因素相关的因素 怀孕了。先前的研究还没有充分控制这种混淆。 家庭和社会背景的影响。最后，调查人员提供了 否认堕胎研究与相关研究之间的概念和经验联系 妊娠意向调查问题分析。尽管研究表明 表明堕胎的可获得性与不想要的孩子有关， 没有人试图将堕胎的可用性纳入一个 对意外分娩后果的分析。 这项拟议的研究解决了以下问题：1)是否存在 意外怀孕与儿童发育之间的关系？2)这是 来自不同数据源的样本之间的关系是否稳定？3) 意外出生和儿童发育之间的关系会发生变化吗？ 什么时候控制与家庭环境相关的未观察到的因素？4) 堕胎机会与#年的调查措施之间的关系是什么？ 怀孕意向？是否有证据表明意外出生，如 在调查中衡量，在两者之间的关系中起到调解作用 堕胎机会和儿童发展？或者堕胎的途径有没有 对儿童发育的直接影响，使怀孕保持不变 分娩的意图？6)测量怀孕的时间 意图(事后与事前)更改对以下影响的估计 怀孕意向对孩子结局的影响。

DESCRIPTION: Unintended pregnancy has been linked to less adequate prenatal care, low birth weight, as well as increased risk of infant mortality, child abuse and developmental deficits. The association between unintended pregnancy and child development has lead experts to recommend increased efforts to reduced unintended pregnancy. However, evidence on whether unintended pregnancies cause adverse birth and developmental outcomes is surprisingly sparse. The proposed research will investigate empirically the causal link between unintended pregnancy and child health and development, and adverse parental behaviors that affect child health and development. The proposed research improves on previous studies in several ways. First, the investigators use two complementary sources of data: the NLS and NMIHS. The two sources of data broaden the number of outcomes that may be analyzed and allow us to test the robustness of the findings of the proposed study. Second, the investigators exploit information on siblings and first cousins to control for unobserved factors related to both child outcomes and unintended pregnancy. Prior studies have not adequately controlled for the confounding effects of family and social background. Finally, the investigators provide a conceptual and empirical link between studies of denied abortion and analyses of survey questions on pregnancy intentions. Although research has suggested that abortion availability is related to unwanted childbearing, there has been no attempt to incorporate abortion availability into an analysis of the consequences of unintended births. The proposed research addresses the following questions: 1) Is there a relationship between unintended pregnancy and child development? 2) Is this relationship robust across samples drawn from different data sources? 3) Does the relationship between unintended births and child development change when one controls for unobserved factors related to family environment? 4) What is the relationship between access to abortion and survey measures of pregnancy intentions? 5) Is there evidence that unintended births, as measured in surveys, play a mediating role in the relationship between abortion access and child development? Or does access to abortion have a direct effect on child development, holding constant the pregnancy intentions of the birth? 6) Does the timing of the measurement of pregnancy intentions (ex post versus ex ante) change estimates of the effect of pregnancy intentions on child outcomes.
