The prevalence of obesity was found to be twice as high in 11-14 year-old white children when using percent body fat as compared to body mass index (BMI) according to a study from England. BMI vs Percent Body Fat
BMI vs Percent Body Fat: 5.6% boys, 6.1% girls vs 11.9% boys, 15.3% girls
When using BMI, 5.6 percent of boys and 6.1 percent of girls were identified as obese compared to 11.9 percent of boys and 15.3 percent of girls when percent body fat was used.
Inaccuracy of BMI
BMI is the least accurate way of measuring obesity
This study points out the inaccuracy of using BMI to identify people and children who are overweight and obese.
BMI is not the most accurate way of measuring obesity as I heard a nationally-recognized radio doctor on the radio once say.
BMI is probably the least accurate way of measuring obesity.
BMI is a vast generalization of determining obesity which is useful if you are analyzing data on thousands of people.
It is also useful when making calculations on self-reported data.
But for an individual, BMI is the least accurate.
Percent body fat is the most accurate way because it is a direct of fat.
