Abstract
|
BACKGROUND: Many risk factors for suicidal behavior have been identified. Much less has been done to associate risk factors with recurrence of suicidal behavior.
METHODS: We compared prevalence of 30 potential risk factors among 8496 depressive patient-subjects from the BRIDGE consortium with no (NSA, n = 6267), one (1SA, n = 1123), or repeated (≥2) suicide attempts (RSA, n = 1106).
RESULTS: Prevalence of most factors ranked: RSA ≥ 1SA > NSA, with a notable opposite trend for the diagnosis of type II bipolar disorder (BD). Factors independently and significantly more present among RSA than 1SA subjects were: borderline personality, substance abuse, mood-switching with antidepressant treatment, female sex, and unsatisfactory response to antidepressant treatment. There also were notably strong associations of RSA with type I or probable BD and associated factors, including family history of BD, young onset, mixed and psychotic features.
LIMITATIONS: Potential effects of treatment on risk of suicidal acts could not be evaluated adequately, as well as associations between levels of suicidal behavior and eventual death by suicide.
CONCLUSIONS: In a large cohort of depressive patients, there were significant associations not only with suicidal behavior generally, but also with the intensity of suicide attempts.
