The bigger the waist circumference, the bigger the neck circumference is not necessarily. Waist circumference is not directly related to neck circumference. Waist circumference and neck circumference are important indicators to measure health. Especially the neck circumference, is closely related to cardiovascular health. When the neck circumference increases, the high-density lipoprotein cholesterol (also known as "good cholesterol") in the body can be reduced, resulting in more cholesterol not being transported to the liver for metabolism. When the high-density lipoprotein cholesterol in men's blood is lower than 1.04mmol/L and that in women is lower than 1.3mmol/L, the risk of heart disease will increase.
