The results of the comparative study on children’s QOL in 4 Asian countries(Japan, China, Vietnam, Thailand) conducted conjointly by International Inequity Group and Childrearing Inequity Group were presented by researchers from China, Vietnam and Japan.

Significant regional differences in sub-domains of QOL were noted in Vietnam and China, while such regional differences were not found in Japan. Children’s behavioral problems have found to affect their QOL. It is of note that low self-esteem that is characteristic in Japanese children was also present in Thai children.(30. Jan. 2012)
