The study investigated the relationship of cholesterol levels with mortality rates in 10,856 men aged 36 to 65 with up to 14 years of follow up.
The study found:
(a) Those with cholesterol levels between 213-231 mg/dL (5.5-6.0 mmol/l) had a 9.4% decreased risk of death compared to those with cholesterol levels below 190 mg/dL (4.9 mmol/l).
(b) Those with low density lipoprotein (LDL) cholesterol levels between 138-155 mg/dL (3.5-4.0 mmol/l) had an 18% decreased risk of death compared to those with low density lipoprotein (LDL) cholesterol levels below 117 mg/dL (3.0 mmol/l).
(c) Those with high density lipoprotein (HDL) cholesterol levels over 55 mg/dL (1.4 mmol/l) had a 76% decreased risk of death compared to those with high density lipoprotein (HDL) cholesterol levels below 37 mg/dL (.95 mmol/l).
This study shows there is an increase in mortality at low levels of total cholesterol, LDL cholesterol and HDL cholesterol in middle-aged men.
