Abstract: Objective To analyze the distribution features of systemic vascular resistance(SVR)disorder in healthy subjects in Guangxi province．Methods SVR and systolic blood pressure(SBP)，diastolic blood pressure(DBP)，mean arterial pressure(MAP)，pulse pressure(PP)， cardiac output(CO)，cardiac index(CI)，stroke volume(SV)，stroke index(SI)，left ventricular ejection time (LVET)，left cardiac work (LCW) and cardiovascular function were determined with Bioz.com Cardio Dynamics． Results The incidence of SVR disorder in youngster and elder was higher than other subjects .The prevalence of SVR disorders was higher among females than among males(P <0.001)．SVR was positively correlated with SBP，DBP，MAP，PP，LVET，body mass index(BMI)，HR was inversely associated with CO，CI，SV，SI，LCW，and arterial compliance(AC)．CO and MAP were independent influencing factors with SVR．Conclusion SVR disorder is associated with age，sex，and blood pressure in populations in Guangxi province and may be a marker of vascular injury．
