Using the body mass index as a measure of weight-related health, with data from 2014, age-standardised global prevalence of underweight in women and men were 9.7% and 8.8%, respectively. These values were lower than what was reported for 1975 as 14.6% and 13.8%, respectively, indicating a worldwide reduction in the extent of undernutrition. [6]
The BRI models the human body shape as an ellipse (an oval), with the intent to relate body girth with height to determine body roundness. A simple tape measure suffices to obtain waist circumference and height. [1] [2] These values are factored with an eccentricity equation in a calculator. [1] [2

Death rate from obesity, 2019. Obesity is a risk factor for many chronic physical and mental illnesses.. The health effects of being overweight but not obese are controversial, with some studies showing that the mortality rate for individuals who are classified as overweight (BMI 25.0 to 29.9) may actually be lower than for those with an ideal weight (BMI 18.5 to 24.9).

A similar 2016 study found that, of the BMI ranges studied (which ranged from 18.5 to >30), the "normal" 18.5–22.4 BMI range combined with healthy eating, high levels of physical activity, not smoking, and no more than moderate alcohol consumption was associated with the lowest risk of premature death.

When it comes to stroke prevention, the guideline stresses the need for risk assessment—including with a risk assessment calculator that estimates 10-year and 30-year stroke and heart disease ...
However, this belief can be misleading, as BMI doesn’t differentiate between muscle and fat, and it doesn’t account for factors like genetics, age, sex and body fat distribution, says Davis.
