  3. GLOBAL BURDEN OF DISEASE:COMMON CVD RISK FACTORS Risk factor Exposure Variable Theoretical Contribution Minimum to GBD High BP Usual SBP 115mmHg (SD6) 4.4% Tobacco Smoking impact ratio; No use 4.1% oral tobacco use High cholesterol Usual TC 3.8mmol/L (SD0.6) 2.8% High BMI BMI 21kg/m2 (SD1) 2.3% Low fruit and Intake daily 600g (SD50) 1.8%veg.

  5. DRIVERS OF THE CVD EPIDEMIC • Urbanisation • Global trade and marketing developments • Tobacco industry • Physical inactivity Tobacco use, inappropriate diet and physical inactivity (expressed through unfavourable lipid profiles, overweight and raised BP) explain at least 75% of new CHD cases Global CVD

  13. FRAMEWORK CONVENTION ON TOBACCO CONTROL • Key provisions encourage countries to: • Enact comprehensive bans on tobacco advertising, promotion and sponsorship; • Obligate placement of rotating health warnings on tobacco packaging that cover at least 30% (but ideally ≥ 50%) of principal display areas; • Ban use of deceptive terms such as “light” and “mild”; • Protect citizens from exposure to tobacco smoke in workplaces, public transport and indoor public places; • Combat smuggling, including placing of final destination markings on packs; • Increase tobacco taxes Tobacco

  14. PUBLIC HEALTH POLICY • Comprehensive health programs led by primary care • Appropriate balance between primary and secondary prevention • Particularly population approaches (Only 5% in wealthy countries at ideal cholesterol, BP, weight) • Also high-risk approaches to primary prevention (although latter may increase inequalities) • Acute management and secondary prevention • Surveillance and monitoring Global CVD

  15. NCD PREVENTION AND CONTROL 94% 88% 88% 76% 65% 39% Percentage of countries with integration of components of NCD prevention and control programmes in primary health care WHO 2001 Global CVD

  16. PRIORITIES FOR DEVELOPING COUNTRIES • Control strategies, initially based on extrapolation from knowledge from other population, e.g. tobacco control: whole population initiatives • Cross-sectional surveys (ecological comparisons), case-control studies and prospective longitudinal studies for incidence data • Workforce training and capacity building • Low cost, high yield interventions CHD prevention

  17. PRIORITIES FOR DEVELOPED COUNTRIES • Prevention including implementation of proven strategies • Chronic disease strategies • Health inequalities • Primary care strategies • Strategies to combat overweight CHD prevention
