In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
[3] 63% of adults were classified as overweight or obese (a body mass index of 25 or above), a 10 percent increase 1993. [3] More than two-thirds of men and 6 in 10 women were overweight or obese. [ 3 ] 28% of children aged between 2 and 15 years (inclusive) were overweight of them about 15% of children were obese.
Body roundness index (BRI) is a calculated geometric index used to quantify an aspect of a person's individual body shape. Based on the principle of body eccentricity, it provides a rapid visual and anthropometric tool for health evaluation. [1] Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat.
Body fat percentage is more suited for individual assessments, especially when precise body composition is critical. RELATED: 5 Science-Backed Ways To Lose Stubborn Body Fat.
BMI vs. Body Fat. We’ll start at the very beginning: Body mass index (BMI) is a measure of someone’s weight compared to their height whereas body fat percentage is a measure of how much body ...
Since body fat can be measured in several ways, statistics on the epidemiology of obesity vary between sources. While BMI is the most basic and commonly used indicator of obesity, other measures include waist circumference, waist-to-hip ratio, skinfold thicknesses, and bioelectrical impedance. [11]
Body fat percentage is total body fat expressed as a percentage of total body weight. There is no generally accepted definition of obesity based on total body fat. Most researchers have used >25% in men, and >30% in women, as cut-points to define obesity, [41] but the use of these values have been disputed. [42]
WHtR is a measure of the distribution of body fat. Higher values of WHtR indicate higher risk of obesity-related cardiovascular diseases , which are correlated with abdominal obesity . [ 1 ] A waist size less than half the height helps to stave off serious health problems.
