Common approach to childhood obesity in Japan.

Although the prevalence of childhood obesity is plateauing, it remains a social concern. The Japan Society for the Study of Obesity devised criteria for obesity disease as a morbid state that requires medical treatment in 2002. Moreover, the Japanese Ministry of Health, Labour and Welfare announced diagnostic criteria for childhood metabolic syndrome in 2010 because of the increasing number of children with lifestyle-related diseases. The treatment of obesity needs to be prioritized, and three principles, other than behavioral therapy, have been introduced in this study for the general medical treatment of obesity without underlying diseases: (1) diet therapy, (2) exercise, and (3) no pharmacotherapy. However, preventing obesity is more important than its treatment. A previous study reported the tracking of an overweight status from infancy; therefore, it is important to prevent infants from becoming overweight. The concept of the developmental origins of health and disease has been attracting more attention in recent years; however, preventative measures prior to birth should also be considered to reduce the incidence of obesity. Although the methods used to approach the treatment of childhood obesity change with differences in race or lifestyle, those who are engaged in the medical treatment of childhood obesity worldwide can contribute to its treatment and prevention by a mutual exchange of information.
