How are BMI Calculations Used?
BMI calculations are primarily used for recording statistical information on the obesity of the population and determining patients with risk factors for obesity-related health problems. However, these numbers do not take into account many factors that can also affect weight, such as frame size and muscularity. The tool is very easy to use and can be done quickly without any expensive equipment, making it an ideal choice for a clinical setting. It is also commonly used to determine rates for health insurance coverage, as higher BMIs have been associated with more illness and on-going health problems. How Reliable is BMI? The results for BMI are very strongly correlated with overall health. There are varying results and thresholds based on sex, race, and age. These include: • With the same BMI, women generally have more body fat than men • With the same BMI, older people generally have more body fat than younger adults • Elite athletes tend to have high BMIs because of increased muscle
