Childhood obesity
Résumé
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 of childhood obesity
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.
The US Preventive Service Task Force reported that not all children with a high BMI need to lose weight though. High BMI can identify a possible weight problem, but does not differentiate between fat or lean tissue. Additionally, BMI may mistakenly rule out some children who do have excess adipose tissue. It is therefore beneficial to supplement the reliability of a BMI diagnosis with additional screening tools such as adipose tissue or skin fold measurements.
Social stigma of obesity
The first problems to occur in obese children are usually emotional or psychological. Obese children often experience bullying by their peers. Some are harassed or discriminated against by their own family.
