Effect of an online lifestyle intervention on the BMI z-score of Mexican school children: a protocol for an outcome assessor-blinded pilot randomized controlled trial during the COVID-19 pandemic.

Abstract

Introduction: School closures due to the COVID-19 pandemic represent a risk factor for the development of childhood obesity, due to the increase in unhealthy behaviors.
