Ages & Stages Questionnaire - 22 Month in Environmental influences on Child Health Outcomes (ECHO)-wide Cohort - 3rd Release

Ages & Stages Questionnaire - 22 Month
Study Description
The National Institutes of Health launched the Environmental influences on Child Health Outcomes (ECHO) initiative in September 2016. The Program focuses on five pediatric outcome areas: obesity, neurodevelopment, upper and lower airways, pre-, peri-, and postnatal outcomes, and positive health. The ECHO-wide Cohort Study, presented here, incorporates longitudinal data on a growing 30,000 pregnancies and 50,000 children from 69 pediatric cohorts to investigate how exposure to environmental factors — including physical, chemical, biological, social, behavioral, natural, and built environments — impact child health and development. By bringing data together into one large ECHO-wide Cohort, scientists can address questions that no single cohort, or a few working together, can answer. Most of the cohorts existed prior to ECHO, bringing a wealth of extant data for compilation and harmonization, in addition to standardized collection of new essential and recommended data elements. This is the third release of the public use data from the ECHO Cohort Study. This release includes shareable data from all eligible participants at the end of the first funding cycle and retains the data from participants in previous releases if the participant is eligible to share data in this release. As of October 31, 2023, 36,027 pregnancies (among 24,370 pregnant persons) and 35,353 children agreed to participate in new ECHO-wide Cohort data collection. Longitudinal data are collected for pregnancies and life stages of the child to 21 years of age.

研究概况
美国国立卫生研究院（National Institutes of Health）于2016年9月启动儿童健康结局环境影响（Environmental influences on Child Health Outcomes，ECHO）计划。该计划聚焦五大儿科健康结局领域：肥胖、神经发育、上下呼吸道疾病、产前、产时及产后结局，以及正向健康。
本次展示的ECHO全队列研究，整合了来自69个儿科队列的纵向数据，涵盖3万余例妊娠及5万名儿童，旨在探究物理、化学、生物、社会、行为、自然及建成环境等各类环境因素暴露对儿童健康与发育的影响。
通过将多源数据整合为这一大型ECHO全队列，科研人员可解答单个队列或少数队列联合研究无法解决的科学问题。
多数队列早在ECHO计划启动前便已建立，除对新增必要及推荐数据要素开展标准化采集外，还提供了大量可用于整合与协调的现存数据。
本数据集为ECHO全队列研究公开数据的第三版发布成果。
本次发布包含首个资助周期结束时所有符合数据共享条件的参与者的可共享数据；若参与者符合本次发布的数据共享要求，则保留其此前各版发布中的数据记录。
截至2023年10月31日，共计36027例妊娠（涉及24370名妊娠个体）及35353名儿童同意参与ECHO全队列新增数据采集工作。
研究将对妊娠过程及儿童直至21岁的各生命阶段开展纵向数据采集。
