In the past decade, an accumulation of research findings has consistently demonstrated that women's behaviors during their pregnancies can strongly affect the health of their infants at birth. In turn, birth outcomes such as low birth weight or premature delivery have strong negative effects on infant health and survival. The proposed study will seek to determine whether and how the planning status of a birth affects maternal behaviors and infant health outcomes. Our overall strategy is both to investigate the effects of planning status within an analysis of other determinants of maternal behaviors and infant outcomes and to explore the advantages of an integrated model that includes a comprehensive set of measures which play a role in birth outcomes and infant health. The statistical analysis will proceed in four stages, corresponding to four primary hypotheses and to four sets of dependent variables - women's behaviors and the care they obtain during pregnancy, birth characteristics, infant care and infant health. Each stage consists of a number of multivariate analyses, one for each dependent variable included in that stage. The primary hypotheses to be tested in each stage are: (I) during their pregnancy, women carrying unintended pregnancies to term make less use of prenatal care services and conform less to recommended personal practices than women with intended births; (II) through the effects of women's behaviors on pregnancy outcome, unintended births are associated with lower birth weight, shorter gestation and a longer duration of post-delivery hospitalization than intended births; (III) women who have unintended births are less likely to perform infant care practices after the child is born; and (IV) as a result of less attention to infant care, unintended births are more likely to be associated with poor infant health than intended births. Two additional hypotheses will be tested in all four stages of the analysis: (1) unwanted births are more strongly associated with poor prenatal and infant care and with negative birth and infant health outcomes than are mistimed births, and (2) the effects of planning status on women's behaviors during and after pregnancy differ among demographic subgroups of women. The study will make use of two recent nationally representative surveys of women and their births - the 1988 National Maternal and Infant Health Survey (NMIHS) and the 1988 National Survey of Family Growth (NSFG) - which, though similar in the data they contain, differ in some important ways. Parallel analyses of both data sets will have the important advantage of allowing for corroboration of findings. Alternatively, analyses from the two data sources may disagree, but the availability of separate yet similar analyses within one study framework will allow for an evaluation of the stability of the size and direction of the relationships found.

在过去的十年中，大量的研究发现一直始终如一 证明女性在怀孕期间的行为可以强烈 出生时会影响婴儿的健康。反过来，出生结果 由于低出生体重或过早分娩对 婴儿健康和生存。拟议的研究将寻求确定 出生的计划状态是否以及如何影响孕产妇行为 和婴儿健康结果。我们的整体策略都是调查 计划状态在分析其他决定因素的影响 孕产妇的行为和婴儿结果，并探索 集成模型，其中包括一组全面的措施 在出生结果和婴儿健康中的作用。 统计分析将 在四个阶段进行，对应于四个主要假设， 四组因变量 - 女性的行为和他们的关心 在怀孕期间获得出生特征，婴儿护理和婴儿 健康。每个阶段都由许多多元分析组成，一个用于 该阶段中包括每个因变量。主要假设 在每个阶段进行测试是：（i）在怀孕期间，妇女携带 意外怀孕的期限较少使用产前护理服务和 比有意图的女性更符合推荐的个人做法 出生； （ii）通过妇女行为对怀孕的影响 结果，意外出生与较低的出生体重有关 妊娠和交通后住院时间比 预定的出生； （iii）意外出生的妇女不太可能 孩子出生后进行婴儿护理练习； （iv）作为一个 对婴儿护理的关注较少的结果，意外出生的可能性更大 与婴儿健康相关，而不是预期的出生。二 分析的所有四个阶段将对其他假设进行测试： （1）不需要的出生与较差的产前和 婴儿护理和不负面的出生和婴儿健康结果 出生和（2）计划状况对妇女的影响 怀孕期间和之后的行为不同 女性。 该研究将利用两位最近代表 对妇女及其出生的调查 - 1988年的全国母亲和婴儿 健康调查（NMIHS）和1988年全国家庭增长调查（NSFG） - 尽管在其中包含的数据中相似，但在某些重要的 方式。两个数据集的并行分析将具有重要的 允许佐证发现的优势。或者， 来自两个数据源的分析可能不同意，但可用性 一个研究框架中的单独但类似的分析将允许 评估关系大小和方向的稳定性 成立。
