Impact of Enhanced Family Education on BMI Changes in Children and Adolescents With Overweight or Obesity: Study Protocol for a City-Wide Cluster Randomized Controlled Trial

This study protocol addresses the urgent need for effective interventions to combat the increasing prevalence of childhood and adolescent obesity in Guangdong Province. Given the significant underrecognition of the need for consistent reporting to parents, the proposed enhanced family-based educational intervention aims to fill this gap by raising parental awareness and promoting healthier lifestyles among children and adolescents. If successful, this approach could significantly reduce the risk of overweight and obesity in Chinese populations, which account for approximately one-fifth of the world's population. The findings will provide insights into the efficacy of family-centered interventions and underscore the importance of integrating routine parental reporting into existing surveillance programs.
