Experts agree that body mass index (BMI) is used to determine the risk of overweight and obesity-related health problems, but its inaccuracy causes it to go slowly to the lamas. New research, published in the journal PLoS ONE, provides evidence that not only the quantity but also the location of adipose tissue determines the susceptibility to diseases associated with obesity. Thus, a new, more accurate tool ABSI indicator has been developed. Learn how to calculate it!
The ABSI Index
The Abody Shape Index (ABSI) is utilized for the assessment of potential health risks, with its value estimated based on body height, body weight, and waist circumference. The incorporation of this latter parameter renders ABSI more precise than the previously employed Body Mass Index. The team of Prof. Krakauer at the City College of New York calculated the ABSI and BMI of over 14,000 Americans with varied body proportions and sizes. Based on the study results, ABSI appears to be more accurate than BMI in predicting obesity mortality. Individuals with the highest ABSI value had a twofold higher risk of premature death than those with a normal index value. Researchers discovered that in some individuals, even when BMI was within the normal range, ABSI indicated that they might be in a risk zone. Scientists admit that it is too early to determine whether ABSI could become the sole parameter of ,good health”, but they agree that the loss of body weight, especially in the waist area, is effective in combating many health issues.
Computation of the Body Shape Index (ABSI)
Determining the index value requires a bit more effort than the Body Mass Index (BMI). In addition to body weight, the index also takes into account a parameter such as waist circumference (WC). To find out the numerical value of the index, you should use the formula: Body Shape Index (ABSI) = WC/[(BMI^(2/3))*(growth^(1/2))]. If you are not good at mathematics, you can also use the calculator available on this page.
How to understand the result?
If your ABSI is: below 1, you are in the low-risk group. If it is 1, you are in the medium-risk group. If it is above 1, you are in the high-risk group. People with apple-shaped belly fat have higher ABSI values, meaning they have the highest risk of developing diseases associated with excess body weight. People with pear-shaped belly fat, on the other hand, have a lower risk of heart disease. However, they are more prone to osteoporosis, joint degeneration in the lower limbs, and venous problems. If you are not satisfied with your result, consider making some changes to your lifestyle. Maintain a healthy diet and increase your physical activity. Start with small steps, such as reducing salt intake and adequate hydration. Remember to drink at least 2 liters of water a day. Include more fruits and vegetables in your diet and choose products rich in polyunsaturated fats, which lower the bad cholesterol LDL level. Avoid products containing harmful trans fats. Good health will be the best reward for your efforts.
