According to both the WHO and CDC, BMI growth charts for children and teens are sensitive to both age-and sex-specific groups, justified by the differences in body fat between sexes and among different age groups. [5] The CDC BMI-for-age growth charts use age-and-gender specific percentiles to define where the child or teenagers stands as ...
BMI is an accurate reflection of body fat percentage in the majority of the adult population. However it is less accurate in people such as body builders and pregnant women. [13] A formula combining BMI, age, and gender can be used to estimate a person's body fat percentage to an accuracy of 4%. [14]
The normal range for BMI in children vary with age and sex. While a BMI above the 85th percentile is defined as overweight, a BMI greater than or equal to the 95th percentile is defined as obesity by the Centers for Disease Control and Prevention (CDC).
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] The rate of obesity increases with age at least up to 50 or 60 years old. [12] Sex- and gender-based differences also influence the prevalence of obesity.
For children, obesity measures take age into consideration along with height and weight. For children aged 5–19, the WHO defines obesity as a BMI two standard deviations above the median for their age (a BMI around 18 for a five-year old; around 30 for a 19-year old).
Compared to traditional metrics, such as the body mass index (BMI), (which uses weight and height), BRI may improve predictions of the amount of body fat and the volume of visceral adipose tissue. Despite its common use, BMI can misclassify individuals as obese because it does not distinguish between a person's lean body mass and fat mass ...
