Maternal Resilience to Stress, Neonatal Outcomes, and Racial/Ethnic Health Disparities

母亲对压力、新生儿结局和种族/民族健康差异的抵抗力

项目摘要

PROJECT SUMMARY Training: The purpose of this K23 proposal is to prepare Dr. Diana Montoya-Williams for a career as an independent clinician scientist. Her long-term career objectives are to contribute to the development of policies and interventions that diminish health disparities among pregnant minority women and their infants. Her immediate goal is to obtain the knowledge and skills to complete rigorous longitudinal studies of maternal-infant dyads aimed at defining assets that protect women against adverse neonatal outcomes. To meet these goals, Dr. Montoya-Williams and her mentor team have devised a career development plan that integrates: 1) intensive mentorship from successful investigators; 2) focused training in longitudinal cohort and statistical path analyses; and 3) innovative research on the relationship between resilience, stress and adverse neonatal outcome disparities. Research: Significant racial, ethnic and nativity-related disparities exist for birth weight, gestational length and breastfeeding in the U.S. and have major implications for our elevated infant mortality rates. Maternal psychosocial stress has been linked to these adverse neonatal outcomes and is disproportionately experienced by minority women. Resilience is the ability to respond to stress and appears to change in the face of stressors. Higher resilience has been linked to improved outcomes in conditions like diabetes and cardiovascular disease; there is also evidence that resilience can be improved. However, our knowledge of resilience in pregnancy is scarce and a major limitation is the cross-sectional nature of existing data. It is not clear whether resilience changes through the course of pregnancy and whether it modifies the relationship that exists between maternal stress and adverse neonatal outcomes. In addition, resilience may vary by race, ethnicity and nativity but data is limited. Dr. Montoya-Williams’ mentored research will address these key knowledge gaps. By creating a diverse longitudinal cohort of pregnant women, she will: 1) explore the association between resilience, three different types of perceived self-reported stress (acute, intermediate chronic and remote traumatic) and the physiologic manifestations of stress (i.e. allostatic load) at the onset of pregnancy; 2) describe whether resilience measured repeatedly in pregnancy changes in response to acute pregnancy-related stressors; and 3) investigate associations between the trajectory of resilience in pregnancy and adverse neonatal outcomes. Importantly, she will describe any differences that may exist in these relationships for women of different ethnoracial and cultural backgrounds. Summary: Findings from this study will inform an R01 proposal to test resilience interventions that may mitigate the stress-related drivers of neonatal health disparities. Through this award, Dr. Montoya-Williams will also emerge as a leading independent clinician scientist contributing to the amelioration of neonatal racial/ethnic health disparities.
项目总结 培训:这份K23提案的目的是为戴安娜·蒙托亚-威廉姆斯博士的职业生涯做准备 独立的临床医生科学家。她的长期职业目标是为 缩小少数民族怀孕妇女及其婴儿之间健康差距的政策和干预措施。 她的直接目标是获得知识和技能,以完成严格的纵向研究 母婴二元组旨在确定保护妇女免受不良新生儿后果影响的资产。至 为了实现这些目标,蒙托亚-威廉姆斯博士和她的导师团队制定了职业发展计划 这包括:1)来自成功调查人员的密集指导;2)专注于纵向培训 队列和统计路径分析;以及3)关于复原力之间关系的创新研究, 压力和不良新生儿结局的差异。 研究:在出生体重、孕期长度方面存在明显的种族、民族和出生相关差异 和母乳喂养在美国,并对我们较高的婴儿死亡率有重大影响。母性 心理社会压力与这些不良的新生儿结局有关,并且不成比例地 少数族裔妇女所经历的。恢复力是对压力做出反应的能力,在 面对压力源。更高的韧性与改善糖尿病和糖尿病等疾病的结局有关 心血管疾病;也有证据表明复原力可以提高。然而,我们所知道的 孕期的恢复力很少,一个主要的限制是现有数据的横截面性质。它是 不清楚弹性是否会在怀孕过程中发生变化,以及它是否会改变 母体应激与不良新生儿结局之间存在的关系。此外,复原力 可能会因种族、民族和出生地而异,但数据有限。蒙托亚-威廉姆斯博士的指导研究将 解决这些关键的知识差距。通过创建一个不同的纵向孕妇队列,她将: 1)探讨复原力、三种不同类型的自我报告压力(急性、 中级慢性和远期创伤)和应激的生理表现(即恒定负荷) 在怀孕开始时;2)描述在怀孕期间重复测量的弹性是否在 对急性妊娠相关应激源的反应;以及3)调查 妊娠恢复力和不良新生儿结局。重要的是,她将描述任何与 不同民族和文化背景的妇女可能存在于这些关系中。 摘要:这项研究的发现将为R01提案提供参考,以测试弹性干预措施,该干预可能 缓解与压力相关的新生儿健康差距的驱动因素。通过这个奖项,蒙托亚-威廉姆斯博士 还将成为一位领先的独立临床科学家,为改善新生儿健康做出贡献 种族/民族健康差距。
