Abstract

BACKGROUND: A major risk factor for suicide is suicide attempts. The aim of the present study was to assess risk factors for nonfatal suicide attempts.

METHODS The study's cohort consisted of 246,814 soldiers who were divided into two groups: soldiers who made a suicide attempt (n=2310; 0.9%) and a control group of soldiers who did not (n=244,504; 99.1%). Socio-demographic and personal characteristics as well as psychiatric diagnoses were compared.

RESULTS The strongest risk factors for suicide attempt were serving less than 12 months (RR=7.09) and a history of unauthorized absence from service (RR=5.68). Moderate risk factors were low socioeconomic status (RR=2.17), psychiatric diagnoses at induction (RR=1.94), non-Jewish religion (RR=1.92), low intellectual rating score (RR=1.84), serving in non-combat unit (RR=1.72) and being born in the former Soviet Union (RR=1.61). A weak association was found between male gender and suicide attempt (RR=1.36). Soldiers who met more frequently with a primary care physician (PCP) had a higher risk for suicide attempt, as opposed to a mental health professional (MHCP), where frequent meetings were found to be a protective factor (P<0.0001). The psychiatric diagnoses associated with a suicide attempt were a cluster B personality disorder (RR=3.00), eating disorders (RR=2.78), mood disorders (RR=2.71) and adjustment disorders (RR=2.26). LIMITATIONS: Mild suicidal behavior constitutes a much larger proportion than among civilians and may have secondary gain thus distorting the suicidal behavior data.

CONCLUSIONS: Training primary care physicians as gatekeepers and improved monitoring, may reduce the rate of suicide attempts.
