Schools can address childhood obesity by implementing comprehensive programs focused on nutrition and physical activity. These can include providing healthy meal options in cafeterias, offering nutrition education to students and parents, and incorporating physical education classes into the regular curriculum. Schools might also host fitness events and encourage active play during recess. Collaborating with health professionals can provide expert advice, while awareness campaigns can engage the community in promoting active lifestyles and balanced diets, mitigating obesity's prevalence among children.
