Largest research project in U.S. military history, started in 2001, follows 187K service members for 21 years
The largest research project in U.S. military history aimed at studying the long-term effects of post-traumatic stress disorder has now passed the halfway point.
The Millennium Cohort Study, run out of the Naval Health Research Center in San Diego, is a 21-year study that is comprehensively following the lives and habits of 187,000 service members. Researchers began accumulating data 11 years ago, in 2001. The project is scheduled to run another decade, until 2022.
Researchers hope the massive amount of data they collect will help them pinpoint who gets PTSD and why.
