Ethnic differences in suicide behavior in Singapore.

Area of Science:

• Psychiatry
• Public Health
• Sociology

Background:

• Suicide attempts present a significant public health challenge globally.
• Understanding ethnic variations in risk and protective factors is crucial for effective prevention.

Purpose of the Study:

• To investigate ethnic differences in stressors, risk factors, and protective factors among individuals who attempted suicide in Singapore.
• To identify specific factors that may influence suicide risk across different ethnic groups.

Main Methods:

• Retrospective chart review of 626 attempted suicide cases in Singapore (2004-2006).
• Data collected on diagnoses (DSM-IV-TR), sociodemographic characteristics, stressors, risk, and protective factors.
• Statistical analyses included Chi-square tests and logistic regression to compare ethnic groups (Chinese, Malay, Indian, other).

Main Results:

• Women were more likely to attempt suicide but also had more protective factors than men.
• Older individuals had a higher likelihood of multiple risk factors.
• Ethnic variations were observed in psychiatric history and unemployment (risk factors) and most protective factors, but not stressors.
• Indians had significantly higher odds of multiple protective factors compared to Chinese (OR 7.74).

Conclusions:

• Suicide prevention programs in Singapore should consider ethnic-specific approaches.
• Targeting young adults and reinforcing protective factors across diverse ethnic groups is recommended.
• Further research into the nuances of ethnic differences in suicide attempts is warranted.
