PROJECT SUMMARY/ABSTRACT The rates of suicide and suicidal ideation and behaviors (SIB) among Black youth have increased drastically in the past decade, with the rate of suicide rising from 2.55 per 100,000 to 4.82 per 100,000 from 2007 to 2017. As compared to their White counterparts, the risk of suicide for Black youth under 13 years old has doubled in the same time period. The overarching goals of this study are to improve our understanding of the uniqueness and complex etiology of Black youth suicide and SIB through a multi-dimensional approach and to provide valuable information for future policies targeting suicide reduction among the Black youth population. To do so, I will first identify risk and protective factors for Black youth (aged 10-24 years) suicide and SIB by jointly considering individuals’ medical history, neighborhood-level social integration level, and the geographic distributions of neighborhoods and suicide rates. A large electronic health records (EHR) database from multiple healthcare systems across New York City (NYC) will be used so that I can gather enough cases of Black youth suicide and SIB along with their clinical data. Secondly, more culturally sensitive theories are needed to explain the underlying mechanism driving Black youth suicide and SIB. Suicide and SIB tend to cluster in geographic space. Prior research using US county-level mortality data has found that the geographic clustering of suicide rates is affected by both social integration and imitation. Durkheim's social integration theory suggests that the more socially integrated a person is, the less likely one is to end his/her life. Tarde’s imitation theory explains suicide as a result of humans adopting the beliefs and behaviors of others in neighboring areas, suggesting suicide as a contagion. Both the social integration and imitation theories have been tested on the general youth population as well as the aboriginal and Inuit youth population. However, whether they can explain contemporary Black youth suicide and SIB is yet to be evaluated. I will develop a composite measure to quantify neighborhoods’ social integration level, which will be used to evaluate the social integration theory along with the imitation theory on the Black youth population. Finally, the counterfactual effects of these social factors on Black youth suicide and SIB risk reduction will also be evaluated. The proposed study addresses an important public health crisis and the completion of the study will inform the design of social and clinical policies that have greater efficiency in reducing the rates of Black youth suicide and SIB. Given the array of new competencies and the multidisciplinary nature of the proposed work, this K99/R00 award is a necessary step to achieve the candidate’s career goal of leading an interdisciplinary team committed to closing the gaps of youth mental health disparities.

项目摘要/摘要 黑人青年中的自杀和自杀思想和行为（SIB）的发生率急剧增加 在过去的十年中，从2007年到2017年的自杀率从每100,000的2.55增加到每100,000的4.82。 与他们的白人同行相比，13岁以下的黑人青年自杀的风险增加了一倍 同一时期。这项研究的总体目标是提高我们对独特性的理解 通过多维方法，黑人青年自杀和同胞的复杂病因，并提供 对于黑人青年人口减少自杀的未来政策，有价值的信息。为此， 我将首先通过共同确定黑人青年（10-24岁）自杀的风险和保护因素 考虑个人的病史，社区级别的社会融合水平和地理 社区和自杀率的分布。来自大型电子健康记录（EHR）数据库 将使用纽约市（NYC）的多个医疗保健系统，以便我可以收集足够的案例 黑人青年自杀和SIB及其临床数据。其次，更文化敏感的理论是 需要解释驱动黑人青年自杀和同胞的潜在机制。自杀和同胞倾向于 集群在地理空间中。先前使用美国县级死亡率数据的研究发现地理 自杀率的聚集受社会融合和模仿的影响。涂尔干的社会融合 理论表明，一个人在社会上的融合越多，结束他/她的生命的可能性就越小。塔德的 模仿理论解释了人类采用他人的信念和行为的结果 邻近地区，认为自杀是一种传染。社会融合和模仿理论都有 我们对一般青年人口以及原住民和因纽特人的青年人口进行了测试。然而， 他们是否可以解释当代黑人青年自杀和SIB仍有待评估。我会发展一个 复合措施来量化社区的社会融合水平，该水平将用于评估 社会融合理论以及黑人青年人口的模仿理论。最后， 这些社会因素对黑人青年自杀和降低SIB风险的反事实影响也将是 评估。拟议的研究解决了重要的公共卫生危机，研究的完成将会 告知设计在降低黑人青年速度效率更高的社会和临床政策的设计 自杀和同胞。考虑到拟议工作的一系列新能力和多学科的性质， 这项K99/R00奖是实现候选人的职业目标的必要步骤 团队致力于缩小青年心理健康差异的差距。
