Projected impact of urbanization on cardiovascular disease in china

Abstract

Objectives: The Coronary Heart Disease (CHD) Policy Model-China, a national scale cardiovascular disease computer simulation model, was used to project future impact of urbanization. Methods: Populations and cardiovascular disease incidence rates were stratified into four submodels: North- Urban, South-Urban, North-Rural, and South-Rural. 2010 was the base year, and high and low urbanization rate scenarios were used to project 2030 populations. Results: Rural-to-urban migration, population growth, and aging were projected to more than double cardiovascular disease events in urban areas and increase events by 27.0-45.6 % in rural areas. Urbanization is estimated to raise age-standardized coronary heart disease incidence by 73-81 per 100,000 and stroke incidence only slightly. Conclusions: Rural-to-urban migration will likely be a major demographic driver of the cardiovascular disease epidemic in China.© Swiss School of Public Health 2012.
