7,735 men aged 40-59 were followed for nearly 15 years to examine the relationship between low cholesterol levels and causes of mortality.

The study found:
(a) Men with low cholesterol (below 4.8 mmol/l (185 mg/dL)) had a 60% increase in total death rates compared to men with cholesterol between 4.8-5.9 mmol/l (185-228 mg/dL).
(b) Men with low cholesterol (below 4.8 mmol/l (185 mg/dL)) had a significant increase in cancer death rates compared to men with cholesterol between 4.8-5.9 mmol/l (185-228 mg/dL).
(c) Low cholesterol levels were associated with an increased prevalence of several diseases and indicators of ill health.

To conclude: Low cholesterol levels are associated with an increase in death rates especially from cancer.
