Objective: To examine for a relationship between serum cholesterol and suic
idal behavior. Methods: Patients admitted after an overdose (N = 120) were
compared with controls (N = 120) for their serum cholesterol levels. Result
s: Patients who had overdosed had significantly lower serum cholesterol lev
els than controls (mean+/-S.D. 171+/-31 vs. 196+/-30 mg/dl, P < 0.0001). Co
nclusion: These results add to a grouping literature reporting that low ser
um cholesterol is associated with suicidal behavior. (C) 2000 Elsevier Scie
