意外生育对母亲的行为和婴儿的健康有显著的负面影响，这一前提强烈地影响了公共卫生政策和目前关于生殖行为的许多研究。然而，证据基础呈现出复杂的发现。使用来自美国全国家庭成长调查的数据，我们采用了一种怀孕意图的测量方法，该方法结合了错误时机的程度，以及Santelli等人开发的愿望量表（《计划生育研究》，40,87 - 100,2009）。其次，我们研究了意向状态组中母亲特征的变化。第三，我们通过使用倾向得分加权来解释母亲、背景特征与怀孕意图和结果之间的关联。我们发现，加权消除了许多观察到的意向状态与母亲行为和分娩结果的关联的统计显著性，但不是全部。在怀孕早期，不合时宜的和意外的分娩仍然比预期的分娩更不容易被发现。接受早期产前护理或母乳喂养的意外出生较少，意外出生的婴儿出生体重低的可能性也高于预期出生的婴儿。相对于欲望量表最高水平的出生，所有其他出生的人在怀孕早期被识别和接受早期产前护理的可能性都要低得多。
The premise that unintended childbearing has significant negative effects on the behavior of mothers and on the health of infants strongly influences public health policy and much of current research on reproductive behaviors. Yet, the evidence base presents mixed findings. Using data from the U.S. National Survey of Family Growth, we employ a measure of pregnancy intentions that incorporates the extent of mistiming, as well as the desire scale developed by Santelli et al. (Studies in Family Planning, 40, 87–100, 2009). Second, we examine variation in the characteristics of mothers within intention status groups. Third, we account for the association of mothers, background characteristics with their pregnancy intentions and with the outcomes by employing propensity score weighting. We find that weighting eliminated statistical significance of many observed associations of intention status with maternal behaviors and birth outcomes, but not all. Mistimed and unwanted births were still less likely to be recognized early in pregnancy than intended ones. Fewer unwanted births received early prenatal care or were breast-fed, and unwanted births were also more likely than intended births to be of low birth weight. Relative to births at the highest level of the desire scale, all other births were significantly less likely to be recognized early in pregnancy and to receive early prenatal care.
