![]() ![]() ![]() BAI chooses the height and hip circumference measurements to determine body fat. The RFM calculations measured the height and waist size of the individual. When they compared the scans to the BAI, they were deemed to be reasonably accurate. In a study of 233 African-Americans and 1,733 Mexican-Americans, researchers measured the percentage of body fat with DXA. The BAI doesn’t just give you a number this calculation is tied to the percentage of body fat. This measurement is known as the body adiposity index (BAI). While RFM is accurate, there is another alternative to measure body fat. Researchers show that the RFM calculations were more accurate than the other formulas in the field. With these numbers, the RFM is starting to gain traction as a gauge of body fat. When they compared the numbers with the RFM measurements, they were close to those scanned by DXA. In one study, researchers scanned 3,456 patients with the DXA (dual-energy X-ray absorptiometry) body scan, which measures body tissue, bone, fat, and muscle. Men can calculate their RFM by using this formula: 64 – (20 x height/waist circumference).Īll these RFM measurements seem to be accurate, as well. The basic formula for women includes the calculation of 76 – (20 x height/waist circumference) to determine RFM. To determine your RFM measurement, you need to measure your waist and height circumference. Many in the medical field believe that this new measurement system gives a better idea of whether a person is healthy or not. With the RFM, your weight is not important for these measurements. The distance around your waist in relation to the person’s height will calculate your body fat. RFM even accounts for body fat around the waist. While the BMI needs a scale and tape measure for its calculation, you only need a tape measure for RFM. These researchers believe their RFM is more accurate than BMI. This new scale is known as the relative fat mass index or RFM. Some scientists have designed a new and improved scale. The problems with BMI have not been overlooked. In some cases, these scores can flag potential health problems if the person carries a high amount of weight. However, BMI can help track obesity over a period of time and throughout the general population. BMI is great for certain individuals, but most people are advised to find alternatives to figure out their ratio of body fat. In some cases, an athletically fit person can have a BMI which would qualify them as “obese.” With only height and weight as a guide, these charts do count lean muscle in their calculation of body fat. Under the BMI scale, body types are not taken into account to determine body fat. In a 2012 study, those individuals with large waists had a higher risk of developing these health issues. However, some studies are showing a link between high levels of abdominal fat and a higher risk of type 2 diabetes and heart disease. These numbers often don’t take into account the fat carried around the abdomen. BMI measures the weight and height of an individual. There are many issues with the BMI scores. BMI does not reflect gender differences, ages, and muscle mass. Many medical professionals understand that these numbers are not 100 percent accurate. You compare your number to charts of average weights ranging from 14.0 to over 30. If you want to determine your BMI, you must divide your weight (kilograms) by height (in meters) and then divide by your height for a second time. However, scientists are coming up with an improved way to measure body fat. BMI charts have been in use since the 1830s. This method of measurement takes your weight and height to index your body fat level. Have you ever seen those colorful charts depicting the body mass index? The body mass index (BMI) is the most widely used method for determining whether you’re overweight, underweight, or at a healthy level. ![]()
