GPH 98: NCD Prevention

Non-communicable diseases (NCDs) - including cardiovascular disease, cancer, chronic respiratory disease, and diabetes - are now the leading causes of global mortality. Unlike acute infectious outbreaks, NCDs emerge from long-term exposure to behavioural and environmental risk factors.This chapter explores the epidemiology of NCDs, shared risk factors such as tobacco use, unhealthy diet, physical inactivity, harmful alcohol consumption, and air pollution. It examines population-level prevention strategies, regulatory policy, taxation, food reformulation, urban planning, and global action plans.NCD prevention requires shifting focus from individual blame to structural design. Health-promoting environments, policy frameworks, and cross-sector coordination are central to sustainable impact.Prevention becomes architecture - shaping daily choices before disease develops.Key Takeaways* NCDs are the leading global cause of mortality.* Major modifiable risk factors are shared across diseases.* Behaviour is shaped by environment, regulation, and social context.* Population-level interventions outperform individual-only strategies.* Policy tools include taxation, regulation, urban planning, and health promotion.* Global frameworks coordinate NCD prevention efforts.* Sustainable prevention requires multi-sectoral governance.
