简介:BACKGROUND:Intracerebralhemorrhage(ICH)andcoronaryheartdisease(CHD)havethesamepathologicalbase,atherosclerosis,andthesimilarriskfactors,suchassmoking,drinking,hypertension,hyperlipemia,diabetesmellitus,etc;butthedistributionsoftwodiseasesareverydifferentinthepopulations.Thismayberelatedtotheexposureofriskfactorsanddifferenteffectsofriskfactorsontwodiseases.OBJECTIVE:ToanalyzethedistributiondifferenceofriskfactorsforICHandCHDinthepopulationsofTongliaocityofNeiMonggolAutonomousRegion.DESIGN:Retrospectiveanalysis.SETTING:SchoolofRadiationMedicineandPublicHealth,SoochowUniversity;TongliaoHospital,NeiMonggolAutonomousRegion.PARTICIPANTS:Randomsamplingwasusedtoselect6hospitalsfrom10hospitalsaffiliatedtoTongliaoCityofNeiMonggolAutonomousRegion.Totally1672medicalrecordsofpatientswithICHand2195medicalrecordsofpatientswithCHDadmittedtoDepartmentofNeurologyandDepartmentofCardiovascularInternalMedicineofabove-mentioned6hospitalsbetweenJanuary2003andDecember2005werecollectedaccordingtotheinvestigationneed.METHODS:Thesubjects,whosemedicalrecordswereinvolved,wereperformedretrospectiveanalysiswithpre-preparedquestionnaire'StrokeandCoronaryHeartDiseaseEpidemiologicQuestionnaire'.Themaincontentsincluded:①Socialdemographycondition:Thedistributionsofgender,age,nationality,etc.②Previoushistoryofdisease:hypertension,diabetesmellitus,etc.③Relatedriskfactors:systolicbloodpressure,diastolicbloodpressure,totalcholesterol,triglyceride,high-densitylipoproteincholesterol,low-densitylipoproteincholesterol,smoking,drinkingandglucose(GLU).ThedatabaseofEpidatawastransformedtoSPSSdatabase.Single-andmultiple-factornon-conditionalLogisticregressionanalysiswereperformedonthedata,andORvalueand95%CIwerecalculated.Thedistributiondifferencesofriskfactorsfortwodiseaseswerecompared
