Suicide rates are rising. In 2013, it was the third leading cause of death in children ages
10-14. It was the second leading cause of death for ages 15-24. Many risk factors for suicide
have been found. But it is hard to predict. Evidence is growing that some factors that may
make people vulnerable to suicide can be identified before birth or in early childhood.
Researchers want to study vulnerability to suicide. They want to look at different kinds of
development. These include prenatal, social, behavioral, cognitive, and neurologic. They will
do this by linking data from the United States Collaborate Perinatal Project (CPP) to the
National Death Index (NDI). The CPP data are from about 50,000 children born to mothers who
enrolled in the 1960s. The CPP observed and examined about 60,000 pregnancies. Then it
followed the babies from when they were born through age 7. The CPP collected data on things
like family and medical history, economic status, and behavior. The NDI has data on the date
and cause of death.
To link data from the CPP to the NDI in order to study certain precursors to suicide.
Offspring born to women who enrolled in the CPP in 1959-1966 and known to be alive at age 7
(Note: at the start of this study around in 2016, the youngest of those still alive would be
50 and the oldest would be 57 years old).
Data on children from the CPP will be submitted electronically to the NDI. It will be
encrypted and data from the NDI will be deidentified to protect confidentiality. It will then
be merged with existing CPP data. Researchers will analyze the data.
