The suicide rates in Denmark have been declining during the last two decades. The decline was relatively larger among women than among men. All age groups experienced a decline except the very young with stable rates and the very old with increasing rates. ⋯ A meta-analysis of risk factors of repetition of suicide attempt has not been carried out, and the quality of the identified studies did not allow a formal meta-analysis. Large randomised clinical trials examining the effectiveness of interventions on reducing rate of suicide attempt and suicide should have high priority. Suicide is a major public health problem and should be given high priority with regard to prevention and research. (ABSTRACT TRUNCATED)
