Statistical Consulting Service: Epidemiologic Research

研究环境因素对人类健康的影响是研究所使命的重要组成部分。由于这类研究几乎总是观察性的，而不是实验性的，因此对数据的解释是复杂的。在所有阶段，包括概念、设计、分析和解释，良好的统计协作对这项工作的成功至关重要。在过去的一年里，我们在许多项目上都是积极的合作者。其中包括对农业工作的各个方面对成人神经系统和呼吸系统结局的影响的研究，对产前接触有机氯与胎儿和儿童后期结局之间关系的研究，以及对儿童接触铅的决定因素的研究。还包括旨在更好地了解某些生殖条件的生物学和治疗结果的研究。

Studies of the effects of environmental agents on human health are a vital part of the mission of the institute. As such studies are almost always observational rather than experimental, interpretation of the data is complex. Good statistical collaboration in all phases, including conception, design, analysis, and interpretation, is essential to the success of this work. During the current year, we were active collaborators on many projects. Included were studies of the impact of various aspects of agricultural work on neurologic and respiratory outcomes in adults, studies of the relationship of prenatal exposures to organochlorines and fetal and later childhood outcomes, and studies of the determinants of lead exposure in children. Also included were studies aimed at better understanding of the biology of certain reproductive conditions and studies of treatment outcomes.
