Woolcott and his co author dr. In the validation dataset the performance of rfm to estimate dxa measured body fat percentage was overall more consistent than that of bmi among women and men across ethnic groups young middle.
Will The Relative Fat Mass Rfm Replace The Body Mass Index
Rfm measurement body fat. High body fat is associated with increased risks of poor health and early mortality. Richard bergman call the new measure the relative fat mass index or rfm. It plugs your height and your waist circumference into a formula and the resulting number is roughly equal to your body fat percentage. The relative fat mass rfm index estimates body fat percentage based on the ratio of height and waist measurements. The rfm formula needs to be applied in long term studies to see what rfm measure constitutes healthy and unhealthy body weight. Rfm is considered a simple anthropometric procedure easier to estimate than other body fat percentage methods and more accurate than the body mass index bmi.
Their recent study found this simple measure is better at predicting body fat percentage than bmi. Relative fat mass rfm is a simple formula for the estimation of overweight or obesity in humans that requires only a calculation based on a ratio of height and waist measurements. Woolcott richard n. The waist to height ratio to body fat percentage formula comes from relative fat mass rfm as a new estimator of whole body fat percentage a cross sectional study in american adult individuals orison o. Relative fat mass rfm as a new estimator of whole body fat percentage a cross sectional study in american adult individuals. Rfm is a simple anthropometric procedure that is claimed to be more convenient than body fat percentage and more accurate than.
Based on data from 3456 adult patients in the us the rfm measurements closely matched those taken by a high tech dxa body scan widely considered the gold standard for measuring body tissue bone muscle and fat. The rfm reached using the above formulae was found to correspond most. In other words rfm was almost as good a gauge of body fat as a specialist bit of medical equipment and all it needs is a tape. Determining body fat percentage using relative fat mass rfm a recently published study systematically explored more than 350 anthropometric measurements with the aim of identifying a simple linear equation that is more accurate than bmi at estimating whole body fat percentage in both men and women. Scientific reports 2018. The caliper and dxa conversion methodology can be found inside our body fat.
We still need to test the rfm in longitudinal studies with large. Body fat percentage and dxa to caliper to conversion methodology. Dxa scans are used to measure bone density and are considered an accurate way to measure body tissue bone muscle and fat.
