Objective: To examine for a relationship between serum cholesterol and suicidal behavior.
Methods: Patients admitted after an overdose (N=120) were compared with controls (N=120) for their serum cholesterol levels.
Results: Patients who had overdosed had significantly lower serum cholesterol levels than controls (mean+/-S.D. 171+/-31 vs. 196+/-30 mg/dl, P<0.0001).
Conclusion: These results add to a grouping literature reporting that low serum cholesterol is associated with suicidal behavior.
