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, which is determined by the ratio of weight to height. The normal range for BMI in children varies 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 Centers for Disease Control and Prevention. 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.
In the present book, thirteen typical literatures about childhood obesity published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on child’s health concerning obesity. We hope this book can demonstrate advances in childhood obesity as well as give references to the researchers, students and other related people.
