To measure the waist circumference accurately, you should measure it mid-way between the lower rib and the iliac crest (the top of the pelvic bone at the hip), this is the method recommended by the World Health Organization, says Ashwell. This is a much easier thought to hold in mind than BMI, where not only do you have to work out the ratio of your weight in kilos to the square of your height in metres, but also remember what the healthy range is. For example, someone with a 95 centimetre waist and a 100 centimetre hip circumference has a waist-to. It is a simple but useful measure of fat. Divide the waist measurement by the hip measurement. The Waist-to-hip Ratio (WHR) looks at the proportion of fat stored on your body around your waist and hip. Using a tape, measure your waist at its narrowest point, and the hips at their widest point.

Divide the measurement from step 2 by the measurement from step 3. To calculate your waist to hip ratio, follow these steps. Find the widest point of your hips and measure in inches. Last year, Ashwell co-authored a paper on the increasing importance of using Waist-to-Height Ratio (WHtR) to assess cardiometabolic risk, and pleaded for scientists to use a consistent terminology to express the ratio so it can easily be searched for in the literature.Īn advantage of WHtR is the simplicity of the health message “keep your waist circumference to less than half your height”. Find the narrowest point of your waist and measure in inches. However, it does not take into account the distribution of fat around the body.Ībdominal fat affects organs like the heart, liver and kidneys more adversely than fat around the hips and bottom, in terms of cardiometabolic risk. It is a ratio of a person’s weight in kilos to the square of their height in metres. An association was shown of the obesity assessed by WHtR in predicting risk factors for cardiovascular diseases, metabolic syndrome, and diabetes compared to other anthropometric parameters.BMI (short for Body Mass Index) is a widely used measure of obesity. Five manuscripts showed evidence of WHtR being the best anthropometric index when used alone, four showed that both WHtR and WC had the best discriminatory power in predicting cardiovascular risk factors compared to the other indices, and two ranked WHtR at the same performance level as waist-to-hip ratio (WHR) and BMI.

In all studies, the body mass index (BMI) and waist circumference (WC) received special attention for analysis along with WHtR. The receiver-operating characteristic (ROC) curves was the validity measure explored in 13 papers, followed by sensitivity and specificity measures. This is definitely not a peer-review source and might eventually be a good approximation only for white males (or whoever they considered to take these measurements on) but if we believe this image, then the ratio head-to-waist over waist-to-floor is 0.52 0.485 1.072. Sixteen papers were selected, most of which with high methodological quality. The review consisted in a search of papers published on the databases Pubmed, Web of Science, and Lilacs, with no restriction regarding period of publication, using the following combinations: abdominal fat or overweight or obesity and waist-to-height ratio or waist height or waist ht or WHtR or waist to stature ratio or wst stature or WSR or stature and girth. A systematic review was carried out aiming to collect evidence on the use of the waist-to-height ratio (WHtR) on the elderly population, focusing on validity measures to identify the best anthropometric indicator in assessing obesity associated with non-communicable diseases.
