Reports of attempted suicide among Brazilian addicts.

Both substance dependence and depressive mood seem to be associated with increased suicide risk. Clinical information on suicide attempts and depressive symptoms were obtained from a sample of 211 psychoactive substance dependents attending a university clinic program for addicts in Brazil. 49 subjects (23.4%) had attempted suicide at least once, and the frequency of reporting attempts was 4.32 times greater among women than among men. Male addicts also tended to engage in potentially more dangerous attempt methods than women. Depressive male addicts were 2.17 times more likely to have attempted suicide than nondepressive addicted men. Among women, no association could be established between having attempted suicide and the presence of depression. Substance addicts have a relatively high risk of attempting suicide and the co-occurrence of depression seems to increase prevalence of suicidal behavior among men.
