Using Social and Behaviour Change in the Prevention of Overweight and Obesity in School‑aged Children

This guide outlines how social and behaviour change (SBC) approaches can be integrated into UNICEF’s work to prevent overweight and obesity in children aged 5–19 years. It addresses policy development, healthier food environments, and promoting healthy dietary practices. Key strategies include behaviourally informed policy-making, youth activism, choice architecture, social marketing, and community empowerment to shift norms and increase demand for nutritious foods. The guide emphasises tackling unhealthy food marketing and improving access to healthy options through schools and community engagement.
