METHODOLOGY IN REPRODUCTIVE RESEARCH

工作总结：方法的目的 在这里进行的研究是为了准备大型和/或确定性的 研究环境毒物在环境中的作用的项目 生殖结果。方法学研究可以解决一个部分 困难的调查（如测量的有效性），或 他们可能是一个试点，以突出困难，在未来的研究， 已解决，或者它们可能是使用可访问代理的小型研究 （而不是罕见的环境暴露）来阐明 毒素影响生殖健康的机制。今年 方法学研究集中在孕龄结束时， 怀孕生殖流行病学的方法学工作 使用酒精作为典型的代理人正在进行中。年的另一项研究 妊娠期高血压的定义及其治疗进展 这种情况的诊断体征与ICD代码有关， 等国

Summary of Work: The purpose of the methodology studies undertaken here is to prepare for large and/or definitive projects that examine the role of environmental toxicants in reproductive outcome. Methodology studies may address one part of a difficult investigation (such as validity of measurement), or they may be a pilot to highlight difficulties in a future study to be resolved, or they may be small studies using an accessible agent (rather than a rare environmental exposure) to elucidate mechanisms by which toxins affect reproductive health. This year methodology studies have focused on gestational age at the end of a pregnancy. Methodologic work in reproductive epidemiology using alcohol as a prototypical agent is ongoing. Another study in progress addresses definitions of gestational hypertension and how the diagnostic signs of this condition related to ICD codes in this and other countries.
