The study examined the association of cholesterol levels in schizophrenic patients with and without suicide attempts. The study included 16 medication-free schizophrenic patients with and without suicide attempts and in 16 healthy controls.
The study found:
(a) The schizophrenic patients had lower cholesterol levels compared with the controls.
(b) The schizophrenic patients who had attempted suicide had significantly lower cholesterol levels compared with the schizophrenic patients who had not.
(c) Cholesterol levels were lower in violent suicide attempters when compared with non-violent suicide attempters.
The results of the study show that low cholesterol is significantly associated with schizophrenia, especially in suicide attempters and even more so in violent suicide attempters.
