Key result
Prior suicide attempt is linked to ~52% higher all-cause mortality, with elevated CVD death risk.
Cohort
Yes
Little is known about the cause-specific deaths among young suicide attempters from the general population, and the time window for intervention to reduce the elevated rate of death was unclear. We analyzed a nationally representative sample of young adults (17-39 years old) who participated in the third National Health and Nutrition Examination Survey (NHANES III, 1988-1994) and were followed up with vital status through December 31, 2006. The history of attempted suicide was associated with an increased rate for all-cause death (HR = 1.52 [95% CI = 0.92-2.52]) with borderline statistical significance. Previous suicide attempters experienced a 3-fold (HR = 2.68[=1.01-7.09]) increased rate for cardiovascular diseases (CVD), and a 7-fold (HR = 7.10 [95% CI = 1.37-36.9]) increased rate of death due to completed suicide compared with non-attempters. The survival curves of the attempters declined rapidly for the first 3 years of follow-up, and the distance between curves remained consistent starting from the third year to the end of the follow-up. Prevention services should be tailored not only for suicide, but also for cardiovascular diseases among populations with suicidal tendency, and the service should be intensified within first 3 years after suicidal behaviors occur.

Al‐Sayegh et al. (2015) conducted a cohort in History of attempted suicide. History of attempted suicide vs. Non-attempters was evaluated on All-cause death (with cause-specific mortality for cardiovascular diseases and completed suicide) (HR 1.52, 95% CI 0.92-2.52). History of attempted suicide was associated with higher mortality from CVD (HR 2.68; 95% CI 1.01-7.09), suicide (HR 7.10; 95% CI 1.37-36.9), and all causes (HR 1.52; 95% CI 0.92-2.52).
