This paper examined the relationship between low density lipoprotein (LDL) cholesterol and death rates. The study lasted for eight years and included 26,000 men and women.
The study found:
(a) The death rate of men whose LDL cholesterol levels were below 100 mg/dL (2.6 mmol/l) were higher than in men whose LDL cholesterol levels were between 100 mg/dL and 160 mg/dL (2.6-4.1 mmol/l).
(b) The death rate of women whose LDL cholesterol levels were below 120 mg/dL (2.6 mmol/l) were higher than in women whose LDL cholesterol levels were above 120 mg/dL (2.6 mmol/l).
The results from this study show that lower LDL cholesterol levels are associated with an earlier death.
