Abstract
OBJECTIVE: We sought to establish whether low cholesterol concentration may be associated with a personal history of attempted suicide or a family history of completed suicide in psychiatric out-patients on maintenance lithium treatment, who represent a population at risk for suicide. METHOD: We retrospectively reviewed charts regarding 783 out-patients consecutively admitted to a lithium clinic from 1976 to 1999. Individual age- and gender-specific quartile of serum cholesterol concentration were correlated against personal lifetime suicide attempts and completed suicide in first-degree relatives. RESULTS: The proportion of men with a personal lifetime history of attempted suicide, especially if violent, and that of men with history of completed suicide in a first-degree relative were significantly higher among the group with cholesterol concentration in the lowest quartile compared to the group with cholesterol levels above the 25th percentile. CONCLUSION: Low cholesterol concentration should be studied further as a potential biological/genetic marker of suicide risk.File | Size | Format | |
