conditions - obesity

Question 1

definition

Answer 1

“when a child is well above the normal weight for his or her age and height” (Mayo Clinic Staff, 2008).

“Obesity and overweight are a result of an imbalance between food consumed and physical activity” (Centers for Disease Control and Prevention, Division of Nutrition, Physical Activity and Obesity, 2008).

Diagnosis depends on:
The measurement used
The cutoff point which determines whether or not body fat is excessive

In adults, the BMI (body mass index) is used to determine whether an individual is overweight or obese

Due to the changing body shapes of children as they grow and develop over time, there is no agreed upon tool of measurement for obesity in children

Varying classification systems can be utilized
