The issue of pregnancy intetention and contraepective failure continue to cause substantial social concern in the United States. An important aspect of this concern is the persistence of large differences among socioeconomic subgroups in levels of unintended pregnancy, abortion and contractive failure. New survey data have begun to reveal the complexities underlying what has been traditionally considered simply "unintended pregnancy." however, the traditional or core measures continue to be needed to provide consistent monitoring of trends. The proposed project would use new National Survey of Family Growth (NSF) data, as well as data from a new Abortion Provider Survey and a new Abortion Patient Survey, to study in detail pregnancy intention and the interrelationships between planning status, bit want and contraceptive failure, in addition to estimating core measures of unintended pregnancy and conteacrptive failure and discontinuation. We would estimate total and subgroup-specific levels of pregnancy and unintended pregnancy and analyze components of change over time. We will also estimate two indicator of success or difficulty among American couples using contraceptives- the proportions of method users who become accidentally pregnant while using a method and the proportions who discontinue method use for other reasons- as well as to which these indicators differ across methods and across subgroups. We would investigate changes from the mid- 1980's to 2000 in use-failure and discontinuation rates. If unintended pregnancies ending in abortion are highly underrepoted in the 2001 NSF, as they have been in all prior NSFGs, we would use procedures developed under a prior NICHE grant to correct NSF data for abortion under reporting and to calculate more accurate measures of contraceptive use-failure and discontinuation rates and of national pregnancy and unintended pregnancy levels than would be possible from the NSF alone. Findings from this project would contribute to the morning of the Healthy People 2010 adjectives and help to direct their achievement; they would also assist health professionals counseling clients on choice of contraception, and individuals choosing a method; and they would provide assistance to other researchers using NSF data for analysis of pregnancy outcomes.

在美国，怀孕肠道和矛盾失败的问题继续引起实质性的社会关注。这个关注的一个重要方面是，在意外怀孕，堕胎和承包失败水平上，社会经济亚组之间存在巨大差异。新的调查数据已经开始揭示传统上认为只是“意外怀孕”的复杂性。但是，继续需要采取传统或核心措施来提供对趋势的一致监控。拟议的项目将使用新的全国家庭增长调查（NSF）数据，以及来自新的堕胎提供者调查和新的堕胎患者调查的数据，以详细研究妊娠意图以及规划状态，脱位和避孕失败之间的相互关系，除了估计意外怀孕的核心措施以及无意外的妊娠和偶然的失败和持发证的失败和不受欢迎的失败和终结。我们将估计妊娠的总和特异性妊娠水平，并分析随时间变化的组成部分。我们还将估计使用避孕药的两个指标，即美国夫妇的成功或困难 - 使用一种方法，他们在使用一种方法的同时意外怀孕的方法以及由于其他原因而停止方法使用的比例 - 这些指标在方法和子组之间有所不同。我们将在1980年代中期到2000年的使用率和停用率的变化。如果在2001年NSF中，堕胎结束的意外怀孕高度不足，因为它们在所有先前的NSFG中，我们将使用以前的利基赠款中开发的程序来纠正报告中的NSF数据，以便在报告下进行堕胎，并计算出避孕措施的避孕率和全国性的预期率和不可能的怀孕率和不确定性。该项目的发现将有助于2010年健康人民的早晨，并有助于指导其成就；他们还将协助卫生专业人员为客户选择避孕，并选择一种方法；他们将使用NSF数据为其他研究人员提供帮助，以分析妊娠结局。
