To date, there have been very limited studies regarding the clinical epidemiology of attempted suicide in Chinese individuals with
heroin-dependence. The objective of this study was to examine the prevalence and correlates of suicide attempt in Chinese individuals receiving
methadone maintenance treatment for
heroin dependence. Demographic, clinical, and psychosocial data of 603
methadone-maintained patients with
heroin dependence were collected with a standardized self-administered questionnaire. The presence of suicide attempt and
antisocial personality disorder was assessed by using a single question and the Mini-International Neuropsychiatric Interview 5.0. The one-month and lifetime prevalence rates of suicide attempt were 9.5% and 34.2%, respectively. In multivariable logistic regression, lifetime suicide attempt was significantly associated with female gender (OR = 2.81), being 20-39 years old (OR = 2.73), an education level of primary school or lower (OR = 2.07), poor economic status (OR = 3.06), injecting
heroin before
methadone maintenance treatment (OR = 2.92), depressive symptoms (OR = 3.46), anxiety symptoms (OR = 1.88), and
antisocial personality disorder (OR = 2.85). Suicide attempt is very prevalent among Chinese individuals receiving
methadone maintenance treatment for
heroin dependence. Services for patients with
heroin dependence in
methadone maintenance treatment clinics in China should include psychosocial supports, periodic screening for suicide attempt and other suicidal behaviors and, when needed, psychiatric treatment and crisis intervention.
