[Case-control analysis and follow-up study on risk factors of suicide attempt in a rural population in Shandong Province].

In order to prevent suicide behavior and propose a comprehensive strategy for suicide prevention, a cases-control study and then follow-up study in a rural population were conducted. The data were analyzed by Logistic model so as to look for the risk factors of suicide attempts. The results showed that suicide attempts were significantly positive associated with recent stress in life events, mental illness, higher scores for lifetime aggression and impulsivity while suicide attempts were negative associated with higher scores for the quality of life and higher scores for the family cohesion. The study suggested: (1) the most important risk factors for suicide was recent stressful life events followed by the mental illness as the second, (2) the higher scores for lifetime impulsivity was one of the independent risk factor for suicide attempts, (3) the model of suicide in rural population in our country is different from that in western country. It is important to develop strategies of prevention and intervention for this population at higher risk.
