Laws in individual jurisdictions
•
•
Malawi, Kenya, Nigeria, Rwanda, Tanzania,
Ghana and Uganda are among other African
countries that currently criminalize nonfatal

Electronic search of articles on suicide cases
carried out in Malawi since inception of online
newspapers (late 2006)

30 cases were found

alcohol use
Age
Suicide Methods
Psychosocial Stressors
Limitations
•
Print newspapers were not included
• Failed to get all reported cases because
did not meet eligibility criteria
• Sample is too small to generalize the
findings
Discussions
•
Use of media reports is one approach to
understand suicide in developing countries like
Malawi which usually have no organization
acting as central suicide registry12
• Central Suicide registry is important for a
country in order to understand burden and
develop proactive strategies

Discussions
•
Motivation or stressors for suicide in this review
are consistent with several studies11,10,14
•
Findings of suicide methods are different to
hospital-based study which revealed pesticide
poisoning, 66 cases out of 84 (79%) and self
immolation13

Conclusion
•
Suicide is indeed huge but preventable
public health problem
• It requires a concerted public health
response to reduce suicide by reducing
mental illness
• Mental health problems indeed constitute
major risk factor for suicide
Recommendations
Establishment of central suicide registry
 Comprehensive research on extent of
suicide in Malawi

 Psychological autopsies
 Epidemiological studies

Revise current pathway to care
Food for thought
Is decriminalization
or depenalization of
suicide important in
Malawi?
