These nationally representative surveys asked identical questions to 69 341 adults, 21 years and older, concerning the occurrence and timing of suicide attempts.
Additive interactions tests compared the magnitude of trends in prevalence of suicide attempts across levels of sociodemographic and psychiatric disorder groups.
In both surveys, most adults with recent suicide attempts were female (2004-2005, 60.17%; 2012-2013, 60.94%) and younger than 50 years (2004-2005, 84.75%; 2012-2013, 80.38%).
Several prior reports18- 21 have characterized trends in deliberate self-harm events among individuals presenting for emergency medical or mental health care.
As a result, relatively little is known about the underlying epidemiology of suicide attempts and how it may have changed in recent years.
The 69 341 adult study participants included 34 629 in the 2004-2005 cohort and 34 712 in the 2012-2013 cohort.
During the study period, the risk for attempting suicide increased for young adults but did not significantly increase for middle-aged or older adults. »
