DESCRIPTION (provided by applicant): The goal of our study is to examine the influence of adverse intrauterine conditions, or prenatal stress, on newborn and infant body composition and obesity risk. Obesity is one of the most important health issues facing our nation. The underlying causes at the individual level, and the reasons for its rapid increase in the population are not well-understood. Evidence suggests that the origins of obesity and its sequelae can be traced back to the intra-uterine period of life, at which time exposure to suboptimal conditions during development may result in fetal programming of physiological systems that then confer increased risk for obesity in childhood and adult life. The overwhelming majority of human epidemiological studies of fetal programming of obesity have relied on measures of either size at birth (such as low birth weight or small-for-gestational age birth), or fetal and early postnatal growth velocity, as markers of adverse intrauterine exposures. We propose an innovative and novel application of the fetal programming paradigm by emphasizing the use of a set of stress-related intrauterine maternal-placental-fetal (MPF) biological processes as the principal markers of exposure to intrauterine insult because MPF biological stress parameters may act as "sensors" of the quality of the intrauterine environment as well as "transducers" of its effects on the developing fetus and subsequent childhood and adult obesity risk. The specific questions addressed in our study include the following: (1) Do MPF indices of prenatal stress exposure over human gestation predict newborn body composition and change in body composition from birth until 6 months age, after accounting for the effects of other established risk factors for obesity? (2) Are there sensitive periods during gestation when the developing fetus is particularly vulnerable to the effects of prenatal biological stress on body composition? (3) Are MPF biological stress measures of the intrauterine environment more specific and sensitive predictors of newborn and infant body composition than currently-used measures of birth outcomes or fetal and early postnatal growth? (4) What are the consequences of MPF endocrine/immune-related changes in body composition on metabolic function (insulin sensitivity)? (5) Are the effects of prenatal biological stress on body composition mediated through a change in energy balance homeostasis set points and energy flux over time? We propose to conduct a prospective, longitudinal, follow-up study in a population-based cohort of infants born to mothers who will participate in a NIH-funded study of biological and behavioral processes in pregnancy. We will have extensive characterization in this infant cohort over the course of their intrauterine life and birth with all the prenatal measures required to address the above questions, including serial measures of the maternal-placental- fetal endocrine and immune/inflammatory milieu, serial ultrasound-based measures of fetal biometry, clinical measures of obstetric complications, measures of maternal biophysical, sociodemographic, behavioral, psychosocial characteristics, and measures of the birth phenotype. From this cohort we will recruit a sample of 120-140 children at birth and follow them up until 6 months age. We propose two major study assessments at T1=0-2 weeks and T2=6 months age. At each assessment our primary study outcome, child body composition, will be quantified by dual energy x-ray absorptiometry (DXA); total energy expenditure (TEE) will be quantified using the doubly labeled water (DLW) method; and metabolic function (insulin sensitivity) will be quantified from measures of blood glucose and insulin. Infant nutrition and feeding practices will be assessed concurrently using multiple-pass 24h diet recalls. State-of-the-art statistical modeling techniques for parametric and non-parametric repeated measures, time- series data, including generalized additive models, polynomial distributed lag, classification and regression trees, and multivariate regression analysis will be used to address the study aims. The significance and impact of this study derives from the importance of achieving at a better understanding of the underlying causes for increased susceptibility for obesity, thereby informing the development of new markers for early identification of risk and targets for intervention.

描述（由申请人提供）：我们研究的目的是检查不良宫内条件或产前压力对新生儿和婴儿身体成分以及肥胖风险的影响。肥胖是我们国家面临的最重要的健康问题之一。个体层面的根本原因以及人口快速增长的原因尚不清楚。有证据表明，肥胖及其后遗症的起源可以追溯到生命的子宫内时期，此时在发育过程中暴露于次优条件可能会导致胎儿生理系统的编程，从而增加儿童时期和儿童时期肥胖的风险。成人生活。绝大多数关于胎儿肥胖规划的人类流行病学研究都依赖于出生时体型（例如低出生体重或小于胎龄出生）或胎儿和出生后早期生长速度的测量，作为不良宫内胎儿的标志。曝光。我们提出了胎儿编程范式的创新和新颖应用，强调使用一组与压力相关的宫内母体-胎盘-胎儿（MPF）生物过程作为暴露于宫内侮辱的主要标志物，因为MPF生物压力参数可能起作用作为宫内环境质量的“传感器”以及其对发育中的胎儿以及随后的儿童和成人肥胖风险的影响的“传感器”。我们研究中解决的具体问题包括以下内容：（1）在考虑其他既定风险因素的影响后，人类妊娠期间产前压力暴露的 MPF 指数是否可以预测新生儿的身体成分以及从出生到 6 个月大的身体成分变化为了肥胖？ (2) 妊娠期间是否存在敏感期，此时发育中的胎儿特别容易受到产前生物应激对身体成分的影响？ (3) 与目前使用的出生结局或胎儿和出生后早期生长的测量相比，宫内环境的 MPF 生物应激测量是否对新生儿和婴儿身体成分更具体、更敏感？ (4) 强积金内分泌/免疫相关的身体成分变化对代谢功能（胰岛素敏感性）有何影响？ (5) 产前生物应激对身体成分的影响是否是通过能量平衡稳态设定点和能量通量随时间的变化而介导的？我们建议对参与 NIH 资助的妊娠期生物和行为过程研究的母亲所生婴儿进行一项前瞻性、纵向、后续研究。我们将对这个婴儿队列在其宫内生活和出生过程中进行广泛的描述，并采取解决上述问题所需的所有产前措施，包括母体-胎盘-胎儿内分泌和免疫/炎症环境的系列测量、系列超声检查、胎儿生物统计的基础测量、产科并发症的临床测量、母亲生物物理、社会人口统计学、行为、心理社会特征的测量以及出生表型的测量。我们将从这个队列中招募 120-140 名出生儿童作为样本，并对他们进行跟踪直至 6 个月大。我们建议在 T1=0-2 周龄和 T2=6 个月龄时进行两项主要研究评估。每次评估时，我们的主要研究结果（儿童身体成分）将通过双能 X 射线吸收测定法 (DXA) 进行量化；总能量消耗（TEE）将使用双标记水（DLW）方法进行量化；代谢功能（胰岛素敏感性）将通过血糖和胰岛素的测量来量化。将使用多次 24 小时饮食召回来同时评估婴儿营养和喂养方法。将使用最先进的参数和非参数重复测量统计建模技术、时间序列数据（包括广义加性模型、多项式分布滞后、分类和回归树以及多元回归分析）来实现研究目标。这项研究的意义和影响源于更好地了解肥胖易感性增加的根本原因的重要性，从而为开发新的标记物以早期识别风险和干预目标提供信息。
