A Long-term Study of the Association between the Relative Poverty Rate and Suicide Rate in Japan

The Association Between Relative Deprivation, Depression, and Youth Suicide: Evidence From a Psychological Autopsy Study

OBJECTIVE

Suicide is a serious public health concern in China. In the present study, we investigated the specific mechanisms underlying relative deprivation and suicide in rural China.

METHODS

A large psychological autopsy study was conducted in rural China, in which 392 suicides and 416 community-living controls were consecutively recruited. Multiple logistic regression analysis was used to assess the relationship between relative deprivation and suicide, with depression as a potential mediator.

RESULTS

Young people who experienced relative deprivation were at a greater risk of suicide and depression. Depression plays a mediating role in the relationship between relative deprivation and suicide.

LIMITATIONS

Due to the limitations of the data, we cannot know whether there is mutual causation between relative deprivation and depression. The self-reported relative deprivation may also produce some influence on the results.

CONCLUSIONS

The current findings demonstrate the importance of relative deprivation as one of the four sources of psychological strain to explain how relative status is associated with suicide. The findings also can be translated into the clinical and preventive practice for suicide.

Influence of Area-Level Characteristics on the Suicide Rate in Korean Adolescents

OBJECTIVE

We aimed to investigate the influence of area-level factors on adolescent suicide and to determine which variables differ according to age and sex.

METHODS

We selected variables that were available for collection through an online database from 2005 to 2015 in the Korean Statistical Information Service and the Korea Labor Institute. We used administrative districts of Korea in 2017 for geographical classification. We examined the relationships between regional suicide rates and area-level variables in male and female subjects aged 10-14 years and 15-19 years. In addition, we analyzed area-level variables in adolescents aged 15-19 years according to sex.

RESULTS

Our findings indicated that several area-level variables affected adolescent suicide rates, varying according to age and sex. Economic problems were shown to be more associated with suicide in male adolescents than in female adolescents. On the other hand, social fragmentation and health services were shown to be more associated with suicide in females.

CONCLUSION

Suicide in adolescents was attributable to area-level factors such as economic status, social fragmentation, and community health services. By identifying area-level variables affecting adolescent suicide rates, we will be able to contribute to implement mental health policies related to adolescent suicide.

Suicide prevention in low- and middle-income countries: part perceptions, partial solutions

Suicide, a common cause of death in many low- and middle-income countries, has often been viewed through a medical/psychiatric lens. Such perspectives medicalise social and personal distress and suggest individual and medication-based treatments. This editorial argues for the need to examine suicide from a public health perspective and suggests the need for population-based social and economic interventions.
