RT Journal Article SR Electronic T1 Association between suicide attempts and homelessness in a population-based sample of US veterans and non-veterans JF Journal of Epidemiology and Community Health JO J Epidemiol Community Health FD BMJ Publishing Group Ltd SP 346 OP 352 DO 10.1136/jech-2018-211065 VO 73 IS 4 A1 Tsai, Jack A1 Cao, Xing YR 2019 UL http://jech.bmj.com/content/73/4/346.abstract AB Background Suicide and homelessness share many of the same risk factors, but there is little understanding of how they are related to each other.Methods Data on 36 155 US adults (3101 veterans and 33 024 non-veterans) in the National Epidemiological Survey of Alcohol and Related Conditions-III were analysed to examine the association between lifetime homelessness and suicide, net of other factors, in a nationally representative US sample.Results US veterans with homeless histories were 7.8 times more likely to have attempted suicide than veterans with no homeless histories (24.5% vs 2.8%). Non-veterans with homeless histories were 4.1 times more likely to have attempted suicide than those with no homeless histories (23.1% vs 4.5%). Lifetime homelessness was independently associated with lifetime suicide attempts in veterans (AOR=3.75, 95% CI 3.72 to 3.77) and non-veterans (AOR=1.83, 95% CI 1.83 to 1.84).Conclusion The findings suggest a unique link between homelessness and suicide, especially among US veterans. Strategies to synergise homeless and suicide prevention services, particularly in the Veterans Health Administration, may benefit high-risk individuals.
