ObjectiveTo investigate the incidence of hypertension and its influencing factors in community-dwellers at risk for high blood pressure in Minhang District of Shanghai， and to provide scientific evidence for the community management. MethodsA retrospective cohort study was conducted using the electronic health records of community-dwellers at risk for high blood pressure in Minhang District， Shanghai from January 1， 2011 to December 31， 2017. The study end-point was the occurrence of hypertension，and the followup was finished in December 2021. A total of 17 265 community-dwellers at risk for high blood pressure were enrolled in our study. Log-rank test and Cox regression analysis were used to determine the influencing factors. ResultsAfter 6.04 years of follow-up， the hypertension incidence among community-dwellers at risk for high blood pressure in Minhang District of Shanghai was 25.5%. Family history of hypertension （HR=1.250， 95%CI： 1.168‒1.338）， family history of stroke （HR=1.295， 95%CI： 1.080‒1.553）， history of diabetes （HR=1.203， 95%CI： 1.076‒1.345）， daily smoking （HR=1.187， 95%CI： 1.087‒1.296）， overweight （HR=1.393， 95%CI：1.308‒1.484）， obesity（HR=1.903， 95%CI： 1.719‒2.106）， high values of normal blood pressure （HR=1.275， 95%CI： 1.195‒1.359） and advanced age （HR=1.033， 95%CI： 1.030‒1.036） were all risk factors. Emaciation （HR=0.649， 95%CI： 0.500‒0.840） was a protective factors. ConclusionBlood pressure monitoring should be strengthened for people elderly， with family history of hypertension， family history of stroke， diabetes or high values of normal blood pressure， so as to diagnose hypertension early. Timely intervention measures should be taken for community-dwellers with unhealthy lifestyles such as smoking， overweight and obesity.

ObjectiveTo determine the complications of hypertension among local residents in Minhang district of Shanghai， and provide scientific evidence for key preventive intervention. MethodsWe retrieved the data from the electronic health records， in which hypertensive patients were included for community-based management， in Minhang district of Shanghai from January 1st， 2014 to December 31st， 2018. A total of 38 599 hypertensive patients who had not had hypertension related clinical symptom when included in the electronic health records were enrolled in our study. Chi-square test and Cochran-Mantel-Haenszel test were used to determine the complications of hypertension. ResultsThe incidence proportion of complications was 10.77%， of which cerebrovascular damage was the highest （7.44%）， followed by cardiac damage （3.55%） and peripheral vascular damage （0.81%）. The incidence proportions in patients aged 18‒59， 60‒69， 70 and above were 5.53%， 9.61% and 16.19%， respectively. There was significant difference in the incidence proportions of complications among age groups （χ²=668.670， P<0.05）. Cochran-Mantel-Haenszel test showed that in the hypertensive patients aged 60‒69， the incidence proportion of complications in females was lower than that in males （χ²=5.937， P<0.05）. However， in those aged above 70， the incidence proportion of complications in females was higher than that in males （χ²=11.619， P<0.05）. ConclusionIn patients with hypertension， the incidence proportions of cardiovascular and cerebrovascular diseases remains relatively high in Minhang district of Shanghai. Additionally， both age and gender have influence on the incidence of complications.
