Public health strategies play a vital role in reducing the growing global burden of diabetes. Effective prevention requires a combination of lifestyle interventions, population-based education, and supportive health policies. Programs promoting balanced nutrition, physical activity, and early screening can significantly delay or prevent diabetes onset. Governments and health organizations are focusing on creating healthier environments through food labeling regulations, urban planning for active living, and public awareness campaigns. Collaborative efforts between healthcare providers, policymakers, and communities ensure sustainable outcomes. Strengthening health systems and addressing social determinants of health are essential steps toward preventing diabetes and improving population well-being.
