Abstract: Objective　To analyze blood pressure variability（BPV） in patients with essential hypertension from the local community health service center.Methods　A total of 130 patients with essential hypertension who had visited the local community health service center（Yan'an Rd，Shibei District，Qingdao） were selected as study samples from December 2016 to June 2017.Each patient was followed up in the community health service center once a month with more than three times of follow-up in total.Systolic blood pressure coefficient of variation（CV） was selected to represent BPV and was calculated during follow-up.Comparison was conducted among patients with different mean systolic blood pressure，comorbidities，medication intake and between patients with and without complications.Results　There was no statistical significance in systolic blood pressure CV among patients with different comorbidities and between patients with and without complications（P>0.05）．Statistical significance could be found in systolic blood pressure CV when comparing patients with different mean systolic blood pressure and medication intake（P<0.05）．Lower systolic blood pressure CV could be found in patients with mean systolic pressure<160 mm Hg comparing with those with mean systolic blood pressure≥160 mm Hg（P<0.05）．Patients who took medicine regularly showed lower systolic blood pressure CV than those who did not take medicine regularly（P<0.05）．Conclusion　Mean systolic blood pressure and medication intake have an impact towards long term BPV.Medical workers in community health service centers shall not only pay attention to the mean blood pressure of patients with essential hypertension，but also pay attention to their BPV.
