To calculate your WHR, follow the following simple steps: A high WHR is also a more accurate predictor- than BMI-to predict adverse outcomes in trauma patients.WHR is considered a more accurate tool than BMI to predict hypertension.What are the advantages of using this method? Used in conjunction with BMI it is a more accurate way to evaluate your weight and health. WHR is a quick and easy way to check how much weight you carry around your middle. WHtR is also considered a more accurate tool for predicting high blood pressure compared to BMI and BMI for people with type 2 diabetes. if your height is 70 inches, your waist must not exceed 34 inches. Ideally, your waist should measure half your height. By factoring in the impact of waist circumference and height on body fat composition, WHtR is a good predictor of health risk. But adults with the same waist circumference measurement will not have the same body fat percentage if their heights are unequal. It factors in height, which is a proven predictor for hypertension and diabetes, and body fat percentage, which is an independent risk factor for heart disease.īy and large, in the same BMI range, people of shorter stature have noticeably plumper midsections than taller individuals. WHtR is also one of the most accurate anthropometric indexes to screen for health risks. These radios are good determinants not just for weight loss but also predictors of non-communicable chronic diseases like BP, diabetes and cardiovascular problems. These include measurements like Waist-to-Hip Ratio and Waist to Height Ratio (WHtR). For more accuracy or health risks from excess weight or to measure weight loss, there are other measurements that are more accurate for certain adult populations. While BMI is one of the most popular tools to determine body mass, it is by no means infallible. PregnancyīMI cannot, for obvious reasons, be used as a health indicator for pregnant women. For this reason BMI charts for children between two and 20 years factor in age-and gender as well. AgeīMI charts for children are not the same as for adults, as BMI changes substantially in children as the volume of fat carried varies with sex and age. ![]() This is because men tend to have more muscle mass, whilst women are often pear shaped, I.e. BMI charts for adult males differs from BMI charts for females. When calculating BMI it is important to consult the correct chart. People of South Asian origin, for instance, are often routinely found to be suffering from diseases like diabetes despite having a normal BMI. EthnicityĮthnic origin also affects BMI, which limits its use as a risk predictor for lifestyle diseases. Thus BMI is not sensitive to the difference between adipose tissue and lean muscle mass. by virtue of their higher muscle mass, will be adjudged overweight or obese, despite having a lean midsection. Since muscle is heavier than fat, heavily muscled people, like athletes, weightlifters, boxers, etc. In other words, it doesn’t take into account that taller people have different linear proportions (broader frames) than shorter people. The mathematics of calculating BMI by dividing weight means that it returns too large a number for short people and too small a number for taller people: short people will be rated as being thinner and tall people fatter than they actually are. 1.7 meters, and your weight is 65 kg, your BMI is To calculate your BMI, simply divide your weight-measured in kilograms-by your height squared-measured in meters The WHO today recognizes the validity of the Body mass index (BMI) and has set the following ranges to determine the distinction between being thin and being overweight or obese. It is a simple numerical measurement that enables the classification of people on the basis of their body composition. In the mid-19th Century, Adolphe Quetelet, a Belgian mathematician, devised the system of Body Mass Index (BMI) to more accurately measure this correlation.īody Mass Index is thus the ratio to body weight (measured in kilograms) to height (measured in meters). ![]() The correlation of height to weight is one of the most obvious determinants of obesity.
