geographical variations in hypertension prevalence awareness treatment and control in china findings from a nationwide and provincially representative survey objectives hypertension has been the most important risk factor for disease burden in china we aimed to conduct the first national spatial analysis of hypertension status awareness treatment and control in chinamethods choropleth maps were used to examine the spatial patterning of hypertension awareness treatment and control in a nationally and provincially representative sample of 174389 adults from the 2013 to 2014 china chronic disease and risk factors surveillance multilevel regressions were used to analyze each outcome across provinces counties towns and villagesresidential committees and to test the proportion of arealevel variances explained by known risk factorsresults hypertension prevalence was highest in the north eg liaoning377 and lowest in the south eg hainan179 among participants found to have hypertension awareness was generally low especially in the south eg guizhou180 receipt of treatment among those who were aware of their hypertension status was above 70 in all provinces except for tibet 377 and guizhou 545 control of hypertension among those receiving treatment sbp140 and dbp90mmhg was generally low especially in northeastern and southwestern provinces adjustment for demographic socioeconomic and behavioral factors weight status healthcare use and urbanization of residence accounted for 577 of variation between provinces in hypertension status 485 in awareness 476 in treatment and 180 in controlconclusion hypertension is spatially patterned in china and there is an unmet need at each step from diagnosis to receiving treatment and achieving controlled hypertension geographically targeted strategies are required to enhance hypertension prevention and management in china
