项目摘要
According to the “prenatal programming of mental illness” hypothesis, the prenatal period is one of the earliest
sensitive periods in development when maternal psychosocial stress exposure can have enduring effects on
offspring mental health. Currently, many measurement tools exist to characterize the occurrence of maternal
psychosocial stress exposure (e.g., depression; anxiety, stressful life events, etc). However, these measures
may not fully record the presence and timing of these experiences, especially when administered to mothers
retrospectively. To better assess the biological consequences of maternal psychosocial stressors on children,
objective tools are additionally needed to capture the prenatal and perinatal presence and timing of maternal
stressful life experiences. With a broader array of available tools, our field will be better poised to identify
children who are most vulnerable and intervene. Our group has been exploring children’s shed primary teeth
as objective and non-invasive tools that record the occurrence and timing of pre- and perinatal stressful life
events. Since teeth provide a fossilized record of their formation process, our working hypothesis is that early
life stressors– and particularly the timing of these psychosocial events – can be non-invasively measured in
shed teeth that began forming in utero. In this R21, we will test this hypothesis across two aims by analyzing
data collected from a separately-funded study called STRONG (Stories Teeth Record of Newborn Growth).
STRONG was funded in 2019 to build a biorepository of teeth from children whose mothers were exposed to
the 2013 Boston Marathon Bombing and manhunt events. In Aim 1, we will use techniques standardly
deployed in anthropology/archaeology (e.g., microCT imaging; histology; light microscopy) alongside newer
approaches (e.g., laser confocal microscopy) to derive a stress and other markers in teeth and determine the
parameters for when and how the Marathon bombing is visible in shed teeth. In Aim 2, we will pair these tooth-
based measures with subjective (self-report and electronic-health records) data of the bombing exposure to
compare the strength of the association between these two sets of measures on levels of child
psychopathology symptoms. As far as we know, this study would be the first to determine the degree to which
primary teeth mark the presence and timing of maternal psychological stress in relation to a traumatic event. If
validated as biomarkers, teeth would transform the study of sensitive periods by providing a new, non-invasive
measure for capturing and dating pre- and perinatal psychosocial exposures. Teeth could be used alongside
existing tools to screen children for early life stress exposure and to understand its biological consequences.
根据“产前编程的精神疾病”假说,产前时期是最早的一个

后代心理健康目前,存在许多测量工具来表征孕产妇死亡的发生。
心理社会压力暴露(例如,抑郁、焦虑、压力性生活事件等)。但这些措施
可能无法完全记录这些经历的存在和时间,特别是当对母亲进行管理时
回顾性为了更好地评估产妇心理社会压力对儿童的生物后果,
此外,还需要客观的工具,以捕捉产前和围产期的存在和产妇的时间,
紧张的生活经历有了更广泛的可用工具,我们的领域将更好地确定

事件由于牙齿提供了其形成过程的详细记录,我们的工作假设是,
生活压力源-特别是这些心理社会事件的时间-可以通过非侵入性测量,
在子宫里就开始脱落牙齿在本R21中,我们将通过分析两个目标来测试这一假设。
这些数据来自一项名为STRONG(新生儿成长的故事牙齿记录)的独立资助研究。
STRONG于2019年获得资助,用于建立一个牙齿生物储存库,这些牙齿来自母亲暴露于
2013年波士顿马拉松爆炸和搜捕事件。在目标1中,我们将使用标准的技术
部署在人类学/考古学中(例如,microCT成像;组织学;光学显微镜),
