This paired case-control study aimed to compare characteristics between suicide attempters with high and low suicide intent in rural China. We evaluated 409 suicide attempters and their paired controls who were matched with the same gender, age (a difference of no more than 3 years), and similar residence. Compared to paired control, suicide attempt with high and low suicide intent shared the 3 common risk factors of negative life event, high depression score, and low social support score. In addition, mental disorder was an independent risk factor of suicide attempt with high intent. Having a low education level and occupation as a farmer were risk factors of suicide attempt with low intent. Mental disorder and depression were associated with a significantly increased risk of suicide attempt with high intent compared to low intent. Depression was found to be related to suicide attempt with high intent compared to low intent in the subgroups of male or female aged 35-54 or 55-70 years. Distinct characteristics were found in the suicide attempters with different intent. These findings are important and the aim is to transform them into concrete ideas for the prevention of suicide attempt in rural China.
