For the past 10 years, the National Institutes of Health has been funding a study following 100,000 children from birth to age 21 to track the effects of environmental and biological factors on their health.
Now, 10 years and $1.3 billion dollars later, the National Children's Study has been cancelled, according to Kaiser Health News.
The study received questioning and criticism over its design, research methodology and management, raising concerns about whether the study should continue, according to the report. An NIH group was tasked with investigating and evaluating these concerns.
"Based on the working group's findings and internal deliberation, I am accepting…findings that the NCS is not feasible," said NIH director Francis Collins, according to the report.
NIH said they will use certain experiences gleaned from the study, such as best practices on data collection and recruitment, to look at links between the environment and child development in smaller studies slated to begin in 2015, according to the report.
NIH has 90 days to submit a new research proposal to Congress, according to the report.
