The objective of the study was to evaluate whether cholesterol levels are associated with death rates and to verify whether or not this is true for both genders. The study lasted 12 years and included a total of 3,257 subjects aged 65–95 years.
The study found:
(a) Women with the highest cholesterol levels had a 34% lower death rate than women with the lowest cholesterol levels.
(b) Men with cholesterol levels over 4.66 mmol/L (180 mg/dL) and a Body Mass Index above 25 had a 28% lower death rate than men with cholesterol levels below 4.66 mmol/l (180 mg/dL) and a Body Mass Index above 25.
(c) Men with cholesterol levels over 4.66 mmol/L (180 mg/dL) and a Body Mass Index above 25 had a 38% lower death rate than men with cholesterol levels below 4.66 mmol/l (180 mg/dL) and a Body Mass Index below 25.
The results of the study indicate that higher cholesterol levels in both men and women are linked to a longer life.
