The waist is the part of the Human abdomen between the rib cage and hips. On people with slim bodies, the waist is the narrowest part of the torso.
Waistline refers to the horizontal line where the waist is narrowest, or to the general appearance of the waist.
To locate the natural waistline, one need simply stand upright and then tilt over to the side keeping the legs and hips straight. Where the torso creases is the natural waistline.

Retrieved Dec 2010Where the waist is convex rather than concave, as in pregnancy and obesity, the waist may be measured at a vertical level 1 inch above the navel. name="Brown">
Strictly, the waist circumference is measured at a level midway between the lowest palpable rib and the iliac crest,
It is important to note that variables such as posture significantly influence the measurement of the waist, and therefore any measurements for a group need to maintain a constant posture between the subjects.
Waist size (waist circumference) is an indicator of abdominal obesity. Excess abdominal fat is a risk factor for developing heart disease and other obesity related diseases. A study published in the European Heart Journal April 2007
showed that waist circumference and waist–hip ratio (defined as waist circumference divided by hip circumference) were predictors of cardiovascular events. The National Heart, Lung, and Blood Institute (NHLBI)
Jewellery, such as a belly chain, may be worn around either the clothing or anatomical waist.
Waist reduction may be used simply to reduce the width of the waist. This change can be permanent or temporary.
Waist training may be used to achieve a certain permanent waist shape, such as a pipe-stem waist.

classifies the risk of obesity-related diseases as high if men have a waist circumference greater than and women have a waist circumference greater than . Further, whether waist circumference or BMI is a better predictor of adverse health outcomes is debatable. For example, those who lift weights may have high BMI but are at relatively low risk for cardiovascular consequences. For these people, waist circumference may be a better indicator of overall health. Some research suggests waist circumference can be predicted from Human brain function, therefore capturing the neurobehavioral pathophysiology of obesity.
