A body mass index (BMI) according to age chart is a graph that shows the relationship between BMI and age for people of different ages. Historically developed by Adolphe Quetelet in 1830, it is a metric used to assess body fat based on height and weight.
BMI is an important measure of health because it can be used to identify people who are overweight or obese. Being overweight or obese increases the risk of developing a number of health problems, including heart disease, stroke, type 2 diabetes, and some types of cancer.
