Main Challenges in Prevention and
Control of Chronic Disease in China
• an enormous burden of premature cardiovascular disease
• low awareness, poor control and limited resources
• evidence-based clinical guidelines for the management of hypertension and cardiovascular disease well established, but not implemented in rural areas
15
• Financing and resourcing health system for prevention and control of nonecommunicable diseases should be well included as an important component of future urbanization plan of China.
