Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health.[1]: 6 The World Health Organization (WHO) classifies obesity by body mass index (BMI). BMI is further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors.[2][3]: xiv In children, a healthy weight varies with sex and age, and obesity determination is in relation to a historical normal group.[4]
