EPA Officials, Advisors Question Children's Study Design Changes

摘要

EPA officials and children's health advisors are raising concerns that ongoing changes to the study design of the National Children's Study (NCS) may prevent the large, longitudinal study from meeting its original goals of assessing American children's health and the environmental factors that could affect normal development and longevity. The project has come under scrutiny in recent years as its budget has swelled and study officials at the National Institutes of Health (NIH) have yet to finalize the design for the main study, which is also yet to begin.
