This study explored the relationship between cholesterol levels and suicide risk in patients with depression. The study included 149 major depressive disorder patients admitted to an emergency room following a suicide attempt, 149 non-suicidal depressive controls, and 251 normal controls.
The study found:
(a) Depressed suicidal patients had 21% lower cholesterol levels than the normal subjects.
(b) Depressed non-suicidal patients had 5% lower cholesterol levels than the normal subjects.
(c) In suicide patients, cholesterol levels were 12% lower in violent suicide patients than non-violent suicide patients.
This study suggests that low cholesterol levels are associated with an increased risk of suicide.
