DESCRIPTION (provided by applicant): This project will link an existing population level dataset consisting of all California births between 1996 and 2006 (over five million children, over 60,000 twin pairs, and over 1 million full and half sibling groups) and outcome data on autism and receipt of developmental services to the CDC's National Assisted Reproductive Technology Surveillance System registry for California infertility clinics for the same period. We will use ths detailed dataset from a large ethnically and geographically diverse state to assess the relationship, if any, between Assisted Reproductive Technology (ART), including in vitro fertilization and related procedures, and autism and to identify the pathways through which this association operates. ART and autism have both increased rapidly in recent decades, and although a relationship is widely suspected, existing research has reported mixed and inconclusive findings, largely a result of insufficient samples. Our design, which enables us to identify about 50,000 ART births and about 24,000 cases of autistic disorder over ten consecutive years, overcomes previous limitations and promises to enable an accurate estimation of autism risk associated with ART. Further, the detailed information we will have on child, parent and family characteristics, residence at birth, ART methods and procedures, and autism outcomes will allow us to better understand the mechanisms at play. With this information, we can 1) identify whether such an association is confounded by individual characteristics selective for both autism and ART, such as parental age, SES, and infertility factors; 2) identify whether an observed association between ART and autism is uniform across ART protocols or is specific to certain method(s); 3) explore the role of clinic-level factors; and 4) ascertain the temporal and spatial correlates of the association of ART and autism. Against the background of rapidly rising autism prevalence and the increasingly important role of ART in reproductive decision-making, this research has important scientific and public health implications. This project has the potential to make significant contributions to our understanding of the etiology of autism as well as the long-term outcomes of ART births, neither of which are well understood. PUBLIC HEALTH RELEVANCE: The prevalence of autism has increased rapidly over the last three decades, although its causes remain poorly understood; meanwhile the use of Assisted Reproductive Technology (ART) has also increased dramatically, although the long-term risks to children conceived this way remain largely unknown. This project will contribute to public health by creating a unique population- level dataset designed to ascertain any potential association between ART or its subtypes and autism as well as identify the mechanisms of the association. This will better enable individuals and their health care providers to weigh the risks and benefits of ART procedures and to recognize a potentially modifiable risk factor for autism.

描述(由申请人提供)：该项目将链接现有的人口水平数据集，包括1996至2006年间加州出生的所有儿童(超过500万名儿童 60,000对双胞胎和100多万个完全和同父异母的兄弟姐妹)和自闭症的结果数据，以及在同一时期接受美国疾病控制与预防中心加州不孕不育诊所国家辅助生殖技术监测系统登记的发育服务的数据。我们将使用来自种族和地理不同的州的详细数据集来评估辅助生殖技术(ART)(包括体外受精和相关程序)与自闭症之间的关系，并确定这种联系的运作途径。近几十年来，ART和自闭症都迅速增加，尽管人们广泛怀疑两者之间的关系，但现有研究报告的结果喜忧参半，而且没有定论，主要是因为样本不足。我们的设计使我们能够在连续十年内识别约50,000名ART新生儿和约24,000例自闭症障碍病例，克服了以前的限制，并承诺能够准确估计与ART相关的自闭症风险。此外，我们将获得有关儿童、父母和家庭特征、出生时居住地、ART方法和程序以及自闭症结果的详细信息，这将使我们更好地了解起作用的机制。有了这些信息，我们可以1)确定这种联系是否被选择孤独症和ART的个体特征所混淆，如父母年龄、SES和不孕因素；2)确定ART和自闭症之间的观察到的关联在ART方案中是一致的，还是特定于某些方法(S)；3)探索临床水平因素的作用；以及 4)确定艺术与自闭症之间的时间和空间关联。在自闭症患病率迅速上升和ART在生殖决策中的作用日益重要的背景下，这项研究具有重要的科学和公共卫生意义。这个项目有可能对我们的理解做出重大贡献 自闭症的病因以及ART出生的长期结果，这两者都不是很好的理解。 与公共卫生相关：自闭症的患病率在过去30年里迅速增加，尽管其原因仍然鲜为人知；与此同时，辅助生殖技术(ART)的使用也大幅增加，尽管以这种方式受孕的儿童的长期风险在很大程度上仍不清楚。该项目将通过创建一个独特的人口水平的数据集来促进公共卫生，旨在确定ART或其亚型与自闭症之间的任何潜在联系，并确定这种联系的机制。这将使个人和他们的医疗保健提供者能够更好地权衡风险和收益 ART程序，并认识到自闭症的潜在可改变的风险因素。
