项目摘要
Twenty-nine states, the territories of Guam and Puerto Rico, and the District of Columbia have legalized
medical and/or recreational cannabis use. Concurrently, the potency of delta-9 tetrahydrocannabinol (THC)
has increased while perceptions regarding harms associated with regular use have become more permissive,
underscoring the importance of focused effort to evaluate the impact of cannabis use on health and behavior.
In particular, there is growing concern about potential adverse consequences of escalations in prenatal
cannabis use (PCU). Nearly 4% of pregnant U.S. women report past month cannabis use, representing a 1.6-
fold increase in the past decade. The potential impact of PCU on neonatal outcomes, including the neonatal
brain, and early childhood developmental milestones has proven difficult to study in part because PCU co-
occurs with other drug use, most notably tobacco, making it difficult to delineate the specific effects of PCU.
Further, PCU is comorbid with other maternal psychiatric illness (delinquency, externalizing behavior) as well
as familial vulnerability to problem substance use that can confound the interpretation of causal effects of PCU
on offspring brain and behavior. This proposal addresses current challenges in the literature by recruiting
pregnant women from an urban hospital outpatient clinic, where medical records show that ~80% of women
who use cannabis do not use other drugs, with the other ~20% of women who use cannabis reporting using
tobacco but very little to no alcohol or other drugs. Pregnant women with a recent history of cannabis use will
be selected; women reporting prenatal cannabis use only (PCU, n=200) will be compared with women
reporting no prenatal substance use (NPCU, n=200), to evaluate the role of PCU in (Aim 1) birth
characteristics (e.g., birthweight) and neonatal neurobehavior (e.g., excitability); (Aim 2) neonatal subcortical
morphology and structural and functional connectivity in 150 PCU and 100 sociodemographically matched
NPCU infants; (Aim 3) infant social-emotional behavior and temperament at 6, 12 and 18 months of age, as
well as mother-infant interactions; and (Aim 4) the extent to which brain structure and connectivity is related to
infant behavior during early life. Analyses will control for an index of other obstetric characteristics as well as
composite indices of maternal psychosocial health, family history and home environment. Prospective in
design, women recruited within the 1st trimester will be followed, with their offspring until 18 months
postpartum, affording detailed characterization of risk and protective influences that accompany PCU. PCU,
tobacco and other drug use will be biochemically validated. Women reporting PCU are more likely to be socio-
economically disadvantaged and thus, the economic burden of early childhood social-emotional difficulties may
be particularly pronounced in this group. Results from this study will directly impact the well-being of this
understudied population and their infants; it will also inform the development of a rational public health policy
on cannabis use in the United States.
29个州、关岛和波多黎各领地以及哥伦比亚特区已经将
医疗和/或娱乐性大麻使用。同时,δ-9四氢大麻酚(THC)
增加了,而对与经常使用有关的危害的看法变得更加宽容,
强调必须集中精力评估大麻使用对健康和行为的影响。
特别是,人们越来越担心产前检查升级的潜在不良后果,
大麻使用(PCU)。近4%的美国孕妇报告上个月使用大麻,占1.6-
在过去的十年中,增长了一倍。PCU对新生儿结局的潜在影响,包括
大脑和早期儿童发育里程碑已被证明很难研究,部分原因是PCU共同
与其他药物一起使用,最明显的是烟草,因此很难描述PCU的具体影响。
此外,PCU还与其他母亲精神疾病(犯罪,外化行为)共病

一家城市医院门诊部的孕妇,病历显示,约80%的妇女
使用大麻的妇女不使用其他药物,使用大麻的其他约20%的妇女报告使用
烟草,但很少或没有酒精或其他药物。最近有大麻使用史的孕妇将

报告无产前药物使用(NPCU,n=200),以评价PCU在(目标1)分娩中的作用

产后,提供风险和保护性影响,伴随PCU的详细特征。PCU,
烟草和其他毒品的使用将得到生物化学验证。报告PCU的女性更有可能是社会性的,
经济上处于不利地位,因此,幼儿社会情感困难的经济负担可能
在这个群体中尤为突出。这项研究的结果将直接影响这一群体的福祉。
它还将为制定合理的公共卫生政策提供信息
关于美国大麻的使用。
