Waist - wikipedia Waist For other uses , see Waist ( disambiguation ) . Not to be confused with waste . This article needs additional citations for verification .

On people with slim bodies , the waist is the narrowest part of the torso . The waistline refers to the horizontal line where the waist is narrowest , or to the general appearance of the waist . Contents 1 Structure 1.1 Waist measurement 1.2 Waist -- hip ratio 2 Society and culture 2.1 Fashion 2.2 Waist reduction and training 3 History 3.1 Etymology 4 See also 5 References 6 External links Structure ( edit ) Because of this and because the waist is often synonymous with the stomach , one can become confused as to the exact location of the waist . Another confusing factor is that the waistline differs on different people . A study showed that self - reported measurements as opposed to measurement done by a technician , underestimated waist circumference and this underestimation increased with increased body size . In the study , waist circumference measured at the level of the umbilicus was larger than that measured at the natural 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 . Waist measurement ( edit ) Strictly , the waist circumference is measured at a level midway between the lowest rib and the iliac crest . An alternative approximation of high relevance in anthropometry is Small of the Back ( SOB ) + 2cm . In anthropometrics , the location of the waist ( height ) can be predicted as 72 % of the neck height , or between the iliac crest ( 60 % of total height ) and the lowest palpable rib ( 64 % of total height ) . The waist - hip ratio equals the waist circumference divided by the hip circumference . Practically , however , the waist is usually measured at the smallest circumference of the natural waist , usually just above the belly button . In case the waist is convex rather than concave , such as is the case in pregnancy and obesity , the waist may be measured at a vertical level 1 inch above the navel . 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 . The size of a person 's waist or waist circumference , indicates abdominal obesity . Excess abdominal fat is a risk factor for developing heart disease and other obesity related diseases . The National Heart , Lung , and Blood Institute ( NHLBI ) classifies the risk of obesity - related diseases as high if men have a waist circumference greater than 102 cm ( 40 in ) and women have a waist circumference greater than 88 cm ( 35 in ) . A study published in the European Heart Journal April 2007 showed that waist circumference and waist - hip ratio were predictors of cardiovascular events . Waist -- hip ratio ( edit ) Main article : Waist -- hip ratio Waist -- hip ratio is the ratio of the circumference of the waist to that of the hips . It measures the proportion by which fat is distributed around the torso . Waist -- hip ratios of 0.7 for women and 0.9 for men have been shown to correlate strongly with general health and fertility . Colloquially this shape is compared to the hourglass shape . Society and culture ( edit ) Fashion ( edit ) In modern clothing the region referred to as the waist is considerably below the waist as defined anatomically . With the advent of pants and skirts that do not require support from above , the clothing waist moved down to a position where the body starts to expand to form the buttocks and a support is therefore available . However , the waist region remains a highly important measurement and anthropometric landmark in garment construction . Jewellery , such as a belly chain , may be worn around either the clothing or anatomical waist . Waist reduction and training ( edit ) Waist reduction or waist training refer to the act of wearing a corset or other constricting garment to reduce or alter the waistline . The four floating ribs may be permanently compressed or moved by such garments . A girdle may also be used to alter the appearance of the 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 . History ( edit ) Etymology ( edit ) Definition : `` middle part of the body , '' also `` part of a garment fitted for the waist , portion of a garment that covers the waist '' ( but , due to fashion styles , often above or below it ) , probably from Old English * wæst `` growth , '' hence , `` where the body grows , '' from Proto - Germanic * wahs - tu - ( cognates : Old English wæstm , Old Norse vöxtr , Swedish växt , Old High German wahst `` growth , increase , '' Gothic wahstus `` stature , '' Old English weaxan `` to grow '' .
