This qualitative study explored themes that described families with obese children in Chinese society. Eight obese children and their families participated in the study. Six of the children were male and two were female, ranging in age from 7 to 13. The themes found were: over-involvement between allied parent and obese child, coalition, diffused boundary between extended family and nuclear family, lack of conflict resolution, and disengaged couple boundary. In this study, the significant role that may be played by the extended family in contributing to a child's obesity, as well as female power dominance in the domestic sphere are considered. Implications for therapy are discussed.
