Biostatistics and Data Management Core (BDM-Core)

生物统计和数据管理核心(BDM-Core)将提供数据管理和分析支持 到项目项目中。它的服务将包括统计和研究设计指导、方案编制 协助和评价、统计分析和解释结果、数据管理和质量 保证。位于儿童营养研究中心，所有人都可以很容易地接触到BDM-Core 项目负责人。BDM-核心人员将由博士和硕士级别的生物统计学家和一名数据库管理员组成。 核心将处理方案内的二级数据分析请求，并将未识别的数据提交给 NICHD数据和样本中心。 为了促进计划内的协同作用和成本效益，BDM-Core将与Digital 评估核心，以促进TDM和加速度计派生数据集中的结构和可变格式 供所有项目使用。与行政核心的合作将通过为其教育做出贡献来实现 在其电子管理系统中开展外联活动、支持数字和广播事业以及分享相关信息。 将通过配备一个数据库管理员来建立和维护中央RedCap来促进成本效益 所有项目的数据库，支持科学方案编制、数据统一、传播科学数据 所有项目的技术知识、成果讨论和解释，以及促进 长期可持续性。BDM-核心成员在评估肥胖风险和执行方面拥有专业知识 功能结果，在几个先进领域有多年经验，如临床试验，非 随机观察性研究、研究设计和样本量估计、纵向数据分析、 广义线性混合模型、多水平结构方程建模、因果推断、缺失数据。

The Biostatistics and Data Management Core (BDM-Core) will provide data management and analysis support to the program projects. Its services will include statistical and study design guidance, protocol preparation assistance and evaluation, statistical analysis and interpretation of results, data management and quality assurance. Housed in the Children’s Nutrition Research Center, the BDM-Core is easily accessible to all Project leads. BDM-Core personnel will consist of PhD- and MS-level biostatisticians and a database manager. The Core will handle requests for secondary data analysis within the program, and submit de-identified data to the NICHD Data and Specimen Hub. To promote synergy and cost-effectiveness within the program, the BDM-Core will collaborate with the Digital Assessment Core to facilitate the structure and variable formats in TDM and accelerometer-derived data sets for use by all projects. Collaboration with the Administrative Core will occur by contributing to its educational outreach activities, DSMB support, and sharing of pertinent information in its Electronic Management System. Cost-effectiveness will be promoted by housing a database manager to build and maintain a central REDCap database for all projects, support for scientific programming, data harmonization, dissemination of scientific and technical knowledge, results discussion and interpretation across all projects, and activities to promote long-term sustainability. BDM-Core members have expertise in assessing obesity risk and executive functioning outcomes, with years of experience in several advanced areas, such as clinical trials, non- randomized observational studies, study design and sample size estimation, longitudinal data analysis, generalized linear mixed models, multilevel structural equation modeling, causal inference, missing data.
