背景：青少年比老年妇女更有可能生下低体重婴儿或早产，当他们生第二胎时，风险可能特别高。确定这些结果的预测因素在第二个十几岁的孩子是必不可少的发展preventive strategies.METHODS：出生证明数据为1993-2002年被链接到确定第二胎密尔沃基青少年。预测有一个低出生体重的第二个婴儿或早产的第二个birth被确定使用logistic regression.RESULTS：相同比例的第一个和第二个婴儿是低出生体重（12%），但第二胎更有可能比第一胎早产（15%比12%）。在调整了人口统计学、怀孕和行为特征的分析中，如果母亲在怀孕期间吸烟，第二个婴儿低出生体重或早产的几率会增加（比值比分别为2.2和1.9），产前体重增加不足（1.8和1.4），判读间隔小于18个月（1.6-2.9和1.4-2.3）或黑色（2.7和1.7）。接受过适当产前护理的妇女发生这两种结果的几率都降低了（0.6和0.4）。16岁以下的女性生第二个婴儿体重过轻的几率也会增加。对社会经济特征的进一步调整产生了大致相同的结果。此外，未婚或未确定父亲的妇女在这两个结果的风险增加（各1.5），和贫穷的妇女有低出生体重儿的风险（1.3）。结论：预测不良出生结果包括可修改的行为。针对这些行为的产前干预可能有助于改善结果。性健康和生殖健康观点，2009，41（2）：101-109，doi：10.1363/4110109
CONTEXT: Teenagers are more likely than older women to have a low-birth-weight infant or a preterm birth, and the risks may be particularly high when they have a second birth. Identifying predictors of these outcomes in second teenage births is essential for developing preventive strategies.METHODS: Birth certificate data for 1993-2002 were linked to identify second births to Milwaukee teenagers. Predictors of having a low-birth-weight second infant or a preterm second birth were identified using logistic regression.RESULTS: The same proportion of first and second infants were low-birth-weight (12%), but second births were more likely than first births to be preterm (15% vs. 12%). In analyses that adjusted for demographic, pregnancy and behavioral characteristics, the odds that a second infant was low-birth-weight or preterm were elevated if the mother smoked during pregnancy (odds ratios, 2.2 and 1.9, respectively), had inadequate prenatal weight gain (1.8 and 1.4), had an interpregnancy interval of less than 18 months (1.6-2.9 and 1.4-2.3) or was black (2.7 and 1.7). Women who had received an adequate level of prenatal care had reduced odds of both outcomes (0.6 and 0.4). Women younger than 16 also had increased odds of having a low-birth-weight second infant. Further adjustment for socioeconomic characteristics yielded largely the same results. In addition, women who were unmarried or did not identify a father were at increased risk of both outcomes (1.5 for each), and poor women were at risk of having a low-birth-weight infant (1.3).CONCLUSIONS: Predictors of poor birth outcomes include modifiable behaviors. Prenatal interventions addressing these behaviors could help improve outcomes. Perspectives on Sexual and Reproductive Health, 2009, 41(2):101-109, doi: 10.1363/4110109
