虽然青少年母亲所生婴儿的不良出生结果风险增加，但对这一群体中导致出生结果的因素知之甚少。鉴于过去的研究将伴侣虐待与成年母亲的不良分娩结果联系起来，我们探讨了孕前语言和身体约会暴力与青少年母亲所生婴儿的出生体重和胎龄之间的关系。分析了全国青少年健康波纵向研究I（1995/96）、II（1996）和IV（2007/08）的数据。在第二波访谈之后和20岁之前（n=558）第一次单胎活产的女孩在第四波访谈中自我报告了婴儿的出生体重和胎龄。在第二波访谈之前18个月的约会暴力受害者（口头和身体）是自我报告的。对照组包括第一波年龄；父母教育;怀孕年龄；报告虐待和出生之间的时间间隔；以及儿童时期的身体和性虐待。加权多变量回归模型按种族（黑人/非黑人）分别进行。平均而言，分娩发生在第二波访谈的两年后。几乎四分之一的母亲报告了言语约会暴力的受害者（23.6%），10.1%的母亲报告了身体暴力的受害者。与非黑人青少年母亲相比，黑人母亲的出生体重和言语约会暴力受害的发生率明显较低。在多变量分析中，对于黑人母亲来说，身体约会虐待和生育结果之间的负相关关系随着时间的增加而变得更强。例如，怀孕前身体约会虐待与报告虐待两年后分娩的黑人母亲的出生体重减少0.79公斤（p< 0.001）和胎龄减少4.72周（p<0.01）相关。非黑人母亲的身体虐待与生育结果无关，所有母亲的言语虐待与生育结果无关。减少怀孕前青少年关系中的身体约会暴力可能会改善黑人青少年母亲的生育结果。干预长期暴力可能尤为重要。
Although infants born to adolescent mothers are at increased risk of adverse birth outcomes, little is known about contributors to birth outcomes in this group. Given past research linking partner abuse to adverse birth outcomes among adult mothers, we explored associations between pre-pregnancy verbal and physical dating violence and the birthweight and gestational age of infants born to adolescent mothers. Data from the National Longitudinal Study of Adolescent Health Waves I (1995/96), II (1996), and IV (2007/08) were analyzed. Girls whose first singleton live births occurred after Wave II interview and before age 20 (n=558) self-reported infants’ birth weight and gestational age at Wave IV. Dating violence victimization (verbal and physical) in the 18 months prior to Wave II interview was self-reported. Controls included Wave I age; parent education; age at pregnancy; time between reporting abuse and birth; and childhood physical and sexual abuse. Weighted multivariable regression models were performed separately by race (Black/non-Black). On average, births occurred two years after Wave II interview. Almost one in four mothers reported verbal dating violence victimization (23.6%), and 10.1% reported physical victimization. Birthweight and prevalence of verbal dating violence victimization were significantly lower in Black compared to non-Black teen mothers. In multivariable analyses, negative associations between physical dating abuse and birth outcomes became stronger as time increased for Black mothers. For example, pre-pregnancy physical dating abuse was associated with 0.79 kilograms lower birthweight (p<.001) and 4.72 fewer weeks gestational age (p<0.01) for Black mothers who gave birth two years post-reporting abuse. Physical dating abuse was unassociated with birth outcomes among non-Black mothers, and verbal abuse was unassociated with birth outcomes for all mothers. Reducing physical dating violence in adolescent relationships prior to pregnancy may improve Black adolescent mothers’ birth outcomes. Intervening on long-term violence may be particularly important.
