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.

近十年来，研究成果不断积累 研究表明，女性在怀孕期间的行为会对 影响婴儿出生时的健康。反过来，出生结果如 因为低出生体重或早产会对婴儿产生强烈的负面影响 婴儿的健康和生存。拟议的研究将寻求确定 计划生育状态是否以及如何影响母亲行为 和婴儿健康结果。我们的总体策略是调查 在对其他决定因素的分析中规划状况的影响 母亲行为和婴儿结局，并探索母亲行为和婴儿结局的优势 综合模型，包括一整套可发挥作用的综合措施 在出生结果和婴儿健康中发挥作用。 统计分析将 分四个阶段进行，对应于四个主要假设 四组因变量 - 女性的行为及其护理 怀孕期间获得的信息、出生特征、婴儿护理和婴儿 健康。每个阶段都包含许多多变量分析，其中一个用于 该阶段包含的每个因变量。主要假设 每个阶段要检测的有： （一）在怀孕期间，携带 意外怀孕到足月时较少使用产前护理服务， 与有意图的女性相比，较少遵循建议的个人习惯 出生； （二）通过女性行为对妊娠的影响 结果显示，意外分娩与出生体重较低、身高较短有关 妊娠期和产后住院时间比妊娠期更长 预期生育； （三）女性意外生育的可能性较小 孩子出生后进行婴儿护理； (IV) 作为 由于对婴儿护理关注较少，意外分娩的可能性更大 与预期出生的婴儿健康状况不佳有关。二 其他假设将在分析的所有四个阶段进行测试： (1) 意外出生与产前不良和不良妊娠密切相关。 婴儿护理以及负面的出生和婴儿健康结果 不合时宜的分娩，以及（2）计划状况对妇女的影响 怀孕期间和怀孕后的行为在人口亚组之间存在差异 女性。 该研究将利用最近两个具有全国代表性的 妇女及其生育情况调查——1988年全国母婴调查 健康调查 (NMIHS) 和 1988 年全国家庭成长调查 (NSFG) - 虽然它们包含的数据相似，但在一些重要的方面有所不同 方式。对两个数据集的并行分析将具有重要意义 优点是可以证实研究结果。或者， 两个数据源的分析可能不一致，但是 在一个研究框架内进行单独但相似的分析将允许 评估关系的大小和方向的稳定性 成立。
