This clinical trial aims to compare the adiposity and weight status among mother-child dyads with overweight or obesity who receive the Fam-Ce-HLP intervention with the mother-child dyads with overweight or obesity who did not receive the intervention. The main question[s] it aims to answer are:
* Is there a significant difference in the adiposity and weight status of mother-child dyads with overweight or obesity who received the Fam-Ce-HLP intervention compared with the mother-child dyads with overweight or obesity who did not receive the intervention?
* Is there a significant difference in the health behaviors, obesity stage level, and ripple effect of mother-child dyads with overweight or obesity who received the Fam-Ce-HLP intervention compared with the mother-child dyads with overweight or obesity who did not receive the intervention? Participants will be asked to attend a seven-month program comprising two primary therapies: a three-month intensive behavioral therapy (IBT) and a four-month maintenance behavioral therapy (MBT).
Researchers will compare the intervention group with the treatment-as-usual group (control group) to see if there is a difference in adiposity, weight status, health behaviors, obesity stage level, and ripple effect.
