Background:　Hypertension　is　one　of　the　leading　causes　of　disease　burden　across　the　world.　In　China,　the　latest　nationwide　survey　of　prevalence　of　hypertension　was　ten　year　ago.　More　information　about　hypertension　prevalence　in　China　could　help　to　improve　overall　antihypertensive　health　care.　Methods:　The　total　population　included　421　selected　resident　communities　from　16　provinces　was　1196422.　This　screening　program　was　supported　by　Ministry　of　Health　as　one　of　national　actions　of　stroke　prevention　and　control　and　leaded　directly　by　the　office　of　China　Stroke　and　High　Risk　Population　Screening　Program　affiliated　to　Ministry　of　Health　of　China　with　close　collaboration　of　local　governments　of　the　16　selected　provinces　from　April　2012　to　Dec　2012.　Results:　The　prevalence　rates　of　hypertension　patients　in　study　population　aged　40　and　older　were　22.9　%　in　total,　21.8%　in　men　and　23.9　%　in　women.　The　prevalence　rate　of　hypertension　increased　remarkably　from　10.0%　in　population　age　40-49　to　42.6%　in　population　age　70-79.　The　rate　decreased　to　36.2%　in　population　age　80　and　over.　Urban　population　had　higher　prevalence　rate　of　hypertension　than　rural　population　did　(23.1%　vs　22.6%).　Population　in　eastern　coastal　China　had　higher　prevalence　rates　of　hypertension　than　western　China　(26.6%,　21.7%).　76.3%　of　the　survival　stroke　patients　had　hypertension.　Conclusions:　The　prevalence　rates　of　hypertension　patients　in　study　population　aged　40　and　older　were　22.9　%　in　total,　21.8%　in　men　and　23.9　%　in　women.　Urban　population　had　higher　prevalence　rate　of　hypertension　than　rural　population　did.　Population　in　eastern　coastal　China　had　higher　prevalence　rates　of　hypertension　than　western　China.
