obesity and coronary heart disease
Last reviewed 05/2021
- waist circumference is the most practical marker for abdominal obesity
- overweight and abdominal obesity are associated with other cardiovascular risk factors including small and dense atherogenic LDL cholesterol, low HDL cholesterol, raised triglycerides, elevated blood pressure, insulin resistance, and impaired glucose regulation including diabetes
- weight reduction results in a lower blood pressure, lower LDL cholesterol and triglycerides, higher HDL cholesterol, and an improvement in hyperinsulinaemia and hyperglycaemia (1)
- obese women have four times the risk of CHD than non-obese women (2)
- in men being obese (BMI >30) or overweight is strongly associated with an increase in the risk of atherosclerotic disease (3)
- a cohort study revealed that the adverse effects of overweight on blood pressure and cholesterol levels could account for about 45% of the increased risk of CHD (4)
- NICE state that severe obesity (body mass index greater than 40 kg/m2) affects CVD risk and should be considered when using risk scores to inform treatment decisions (5)
