Abstract
This chapter describes the classification of childhood obesity and the current prevalence and time trends of childhood obesity worldwide. Various references and standards have been used over the past two decades and at present to define overweight and obesity in children, although in general most are based on age-sex-specific body mass index (BMI) cut points (percentile or other cut points), and they can give different estimate of the rates.
Childhood obesity has become a global public health crisis, and the prevalence varied considerable across countries and is still growing in many parts of the world. The prevalence is highest in Western and industrialized countries, but still low in some developing countries. The prevalence also varies by age and gender within and across countries. The WHO Americas and Eastern Mediterranean Regions had higher prevalence of overweight and obesity (30–40 %) than the European (20–30 %), South East Asian, Western Pacific, and African Regions (10–20 % in the latter three). Forty-three million children (35 million in developing countries) were estimated to be overweight or obese; 92 million were at risk of overweight in 2010. The global overweight and obesity prevalence has increased dramatically since 1990, e.g., in preschool age children, from approximately 4 % in 1990 to 7 % in 2010. If this trend continues, the prevalence may reach 9 % or 60 million people in 2020. Vigorous efforts including national policies and programs are needed to combat the epidemic.
