Stroke in the People’s Republic of China: I. Geographic Variations in Incidence and Risk Factors

Abstract: Background and Purpose Stroke is a major cause of death in the People’s Republic of China (PRC), and the geographic distribution of stroke death varies substantially. We conducted an ecological analysis to investigate the relationship of prevalence of hypertension and other risk factors with stroke incidence and mortality in the PRC. Methods The relationship between prevalence of risk factors and stroke incidence and mortality in the PRC was assessed in 29 provinces by examining risk factor data from PRC national surveys and incidence and mortality from the 1986 PRC National Stroke Study. Results A highly statistically significant correlation between prevalence of hypertension and stroke incidence (r=.838, P<.001) and mortality (r=.841, P<.001) was observed. Prevalence of hypertension explained over 70% of the geographic variability in stroke incidence (partial R2=.703) and mortality (partial R2=.707) in the PRC. There was a north-south gradient, with a higher prevalence of hypertension and stroke inciden...
