Childhood obesity
condition where excess body fat negatively affects a child's health or well-being
Childhood obesity is a condition where excess body fat negatively affects a child's health or well-being. As methods to determine body fat directly are difficult, the diagnosis of obesity is often based on BMI. Due to the rising prevalence of obesity in children and its many adverse health effects it is being recognized as a serious public health concern. The term overweight rather than obese is often used when discussing childhood obesity, as it is less stigmatizing, although the term overweight can also refer to a different BMI category. The prevalence of childhood obesity is known to differ by sex and gender.
Classification
Body mass index (BMI) is acceptable for determining obesity for children two years of age and older. It is determined by the ratio of weight to height.
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). Obesity is further categorized as class 1 obesity with BMI at or above the 95th percentile to 119% of the 95th percentile, class 2 obesity with a BMI 120 to 139% of the 95% percentile and class 3 obesity which is 140% or greater of the 95th percentile. The CDC has published tables for determining this in children.

Why this record matters
The phrase “condition where excess body fat negatively affects a child's health or well-being” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q3241451. The Library of Congress control number is sh85093649. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
