This study investigated the association between cholesterol levels and death rates in elderly people. The study lasted for 12 years and included 800 people aged 60-85 years.
The study found:
(a) Those with cholesterol levels above 200 mg/dL (5.1 mmol/L) had a 24% decreased risk of death compared to those with cholesterol levels below 200 mg/dL (5.1 mmol/L).
(b) Those with low density lipoprotein (LDL) cholesterol levels above 130 mg/dL (3.3 mmol/L) had a 27% decreased risk of death compared to those with low density lipoprotein (LDL) cholesterol levels below 130 mg/dL (3.3 mmol/L).
(c) Those with cholesterol levels below 170 mg/dL (4.4 mmol/L) had a 60% increased risk of death compared to those with cholesterol levels above 170 mg/dL (4.4 mmol/L).
(d) Those with high density lipoprotein (HDL) cholesterol levels below 40 mg/dL (1.0 mmol/L) had a 20% increased risk of death compared to those with high density lipoprotein (HDL) cholesterol levels above 40 mg/dL (1.0 mmol/L).
The data from the study shows that low cholesterol leads to an early death.
