The study investigated the relationship between depressive illness and low cholesterol levels in 1,020 elderly men.
The study found that among men aged 70 years and older, depression was three times more common in the group with low cholesterol levels (less than 4.14 mmol/L or 160 mg/dL) than in those with higher concentrations.
Morgan concluded: "Our finding that low plasma cholesterol is associated with depressive symptoms in elderly men is compatible with observations that a very low total cholesterol
may be related to suicide and
violent death".
