ENTREN-F family-system based intervention for managing childhood obesity: Study protocol for a randomized controlled trial at primary care.

Background: Pediatric obesity is a primary public health concern, and designing effective programs for managing it is of the utmost importance. The objective of this study was to describe the protocol study of a three-arm, parallel, randomized controlled trial aimed at assessing the efficacy of a family-system-based intervention ("ENTREN-F" program) for managing childhood obesity, compared to the "ENTREN" program (no "F" - without specific family-system-based workshop) and a control group (behavioral monitoring).

Methods/design: The ENTREN-F program was a multicomponent family-system-based intervention carried out by a multidisciplinary team in the primary health care setting.
