Low serum cholesterol levels are linked to a small but significant increase in suicide completion risk. Past suicide attempts, particularly violent ones, are also associated with lower cholesterol. Cholesterol-lowering treatments did not significantly increase suicide risk.

Area of Science:

  • Neuroscience
  • Epidemiology
  • Psychiatry

Background:

  • Low serum cholesterol has been anecdotally linked to adverse health outcomes.
  • A potential association between cholesterol levels and suicidal behavior warrants investigation.

Purpose of the Study:

  • To systematically evaluate the association between low serum cholesterol and suicide risk.
  • To determine if cholesterol levels differ in individuals with a history of suicide attempts.

Main Methods:

  • A meta-analysis was conducted on existing studies.
  • Data from follow-up studies and case-control studies were synthesized.

Main Results:

  • A statistically significant, albeit small, increased risk of suicide completion was observed in individuals with lower serum cholesterol.

  • Individuals with a history of suicide attempts, especially those involving violent methods, exhibited lower cholesterol levels.
  • Cholesterol-lowering interventions did not result in a significant increase in completed suicides.

    • Conclusions:

    • Low serum cholesterol may be a risk marker for suicide completion.
    • Further research is needed to elucidate the biological mechanisms underlying this association.
    • Clinical interventions targeting cholesterol should consider this potential link.
