| Summary: | BackgroundTwo circulatory diseases, cardiovascular and cerebrovascular diseases have become the leading death causes in China, and their morbidity and mortality are still rising. Revealing the urban/rural-specific, gender-specific and region-specific differences in the order of circulatory diseases ranked by mortality and its changing trend will provide a scientific basis for the prevention and control of circulatory diseases.ObjectiveTo analyze the spectrum of mortality from circulatory diseases ranked by mortality, mainly cardiovascular and cerebrovascular diseases, in China from 2004 to 2015, by areas (urban/rural) , sex and region and its changing trend.MethodsInformation about deaths and mortality due to circulatory diseases stemmed from the data of circulatory disease from 2004 to 2015 defined by National Disease Surveillance System Cause-of-Death Surveillance Data Set. The urban/rural-specific, gender-specific and region-specific differences in the mortality from circulatory diseases and their changing trend were analyzed with χ2 test by SPSS 13.0.ResultsDuring 2004 to 2013, the six circulatory diseases leading to deaths ranked by mortality in a descending order were: cerebrovascular disease, ischemic heart disease, other circulatory diseases, hypertensive heart disease/kidney disease, rheumatic fever and rheumatic heart disease. And the order of these diseases from 2014—2015 was: cerebrovascular disease, ischemic heart disease, hypertensive heart disease/kidney disease, other circulatory diseases, rheumatic fever and rheumatic heart disease. From 2006 to 2015, the mortality of cerebrovascular and ischemic heart diseases increased year by year. From 2004 to 2015, the mortality of hypertensive heart disease/kidney disease increased slowly year by year. There was no significant change in the mortality of rheumatic fever and rheumatic heart disease but a double wave change in the mortality of other circulatory diseases with peaks in 2006 and 2013. The urban/rural-specific mortality: the difference was statistically significant for cerebrovascular disease each year, for rheumatic fever and rheumatic heart disease each year except in 2006 and 2015, for hypertensive heart disease/kidney disease each year except in 2005, for ischemic heart disease each year except in 2015, and for other diseases of the circulatory system each year except in 2004, 2005, 2011 and 2012 (P<0.05) . The gender-specific mortality: the difference was statistically significant for rheumatic fever and rheumatic heart disease, ischemic heart disease and cerebrovascular disease each year, for other diseases of the circulatory system each year except in 2005, and for hypertensive heart disease/kidney disease only in 2005 and 2015 (P<0.05) . The region-specific mortality: the difference was statistically significant for each disease in each year of the period (P<0.05) .ConclusionThere were extremely significant urban/rural-specific, gender-specific and region-specific differences in the mortality of circulatory diseases. The incidence of ischemic heart disease was high in urban areas, while that of other circulatory diseases was high in rural areas. The incidence of rheumatic fever and rheumatic heart disease was high for females, while that of other circulatory diseases was high in males. The region-specific mortality difference was statistically significant for rheumatic fever and rheumatic heart disease, hypertensive heart disease/kidney disease, ischemic heart disease and cerebrovascular disease as well as other circulatory diseases. Therefore, prevention and treatment priorities for circulatory diseases should be determined and targeted interventions should be delivered according to region-specific differences.
