Studies on the effects of prenatal cocaine exposure on infant outcome show an inconsistent pattern of results due, in part, to 1) confounding of cocaine with other substances most notably alcohol; 2) problems in the measurement of prenatal substance exposure; 3) failure to include maternal biobehavioral risk factors related to prenatal substance use that may also affect infant neurobehavioral outcome; and 4) problems with neurobehavioral assessments that may not be sensitive to the effects of prenatal drug exposure. The four objectives of the proposed study are to: 1) determine the combined effects of alcohol and cocaine on infant neurodevelopmental outcome; 2) use sophisticated clinical interview measures of cocaine and alcohol use to provide a more reliable estimate of prenatal substance exposure; 3) include measures of maternal biobehavioral risk factors in addition to measures of prenatal substance exposure that may relate to infant neurobehavioral outcome and 4) use "state of the art" measures from the neurobehavioral battery that we developed for NIDA for the NIH Maternal Lifestyles multicenter longitudinal study of prenatal drug exposure and child outcome. The sample will include 100 infants prenatally exposed to cocaine plus alcohol, only alcohol, and unexposed controls. Marijuana and nicotine exposure, gestational age, and prenatal care will be included as covariates. Mothers will be administered the time line follow-back structured interview method to measure prenatal cocaine and alcohol exposure and a biobehavioral risk factor battery that includes measures of pre-pregnancy substance use history, medical complications, neuropsychological function, mental health issues, familial psychiatric and substance use histories. Infants will be tested at birth and one month on the NICU Network Neurobehavioral Scale and at one month on mother-infant feeding interaction. Data analysis will determine if infants exposed to cocaine and alcohol show poorer neurobehavioral outcome at birth and one month than infants exposed only to alcohol and the effects of maternal biobehavioral risk factors on infant neurobehavioral outcome.

产前可卡因暴露对婴儿结局影响的研究 显示出不一致的结果模式，部分原因是1）混淆 可卡因与其他物质，特别是酒精的混合; 2） 产前物质暴露的测量; 3）未能包括 与产前药物使用相关的母体生物行为危险因素 这也可能影响婴儿的神经行为结果;以及4） 神经行为评估可能对以下因素的影响不敏感 产前药物暴露拟议研究的四个目标是： 1)确定酒精和可卡因对婴儿的综合影响 神经发育结果; 2）使用复杂的临床访谈 可卡因和酒精使用的措施，以提供更可靠的估计 产前物质暴露; 3）包括产妇的措施 除产前物质测量外的生物行为危险因素 可能与婴儿神经行为结果有关的暴露和4）使用 “最新技术水平”从神经行为电池中测量， 为NIDA为NIH产妇生活方式多中心开发 产前药物暴露和儿童结局的纵向研究。的 样本将包括100名产前接触可卡因的婴儿， 酒精、仅酒精和未暴露对照。马立替尼和尼古丁 暴露、胎龄和产前护理将包括在内， 协变量母亲们将被管理的时间线跟进 结构化访谈法测量产前可卡因和酒精 暴露和生物行为风险因素组合， 孕前药物使用史，医疗并发症 神经心理功能，心理健康问题，家族性精神病 和药物使用史婴儿将在出生时进行测试， 在NICU网络神经行为量表上， 母婴喂养互动数据分析将确定是否 接触可卡因和酒精的婴儿表现出更差的神经行为 结果在出生时和一个月比婴儿暴露于酒精和 母亲生物行为危险因素对婴儿的影响 神经行为结果
