Objective   To investigate the condition and impact factors of blood pressure control among 35 – 74 years old hypertension patients in Luohu district, Shenzhen city of Guangdong province and to provide evidences to improve health management of the patients.

  Methods  Using stratified random sampling, we recruited 1 205 hypertension patients aged 35 – 74 years at 10 community health service centres affiliated to Shenzhen Luohu Hospital Group. Face-to-face surveys with a self-designed questionnaire, physical examination and laboratory tests were conducted among the patients during February 2019.

  Results  Of all the patients, 618 (51.3%) had their blood pressure well-controlled. The results of unconditional multivariate logistic regression analysis showed that the patients with following characteristics were more likely to have well-controlled blood pressure: with locally registered permanent residence (odds ratio OR = 1.379, 95% confidence interval 95% CI: 1.088 – 1.748), taking antihypertensive medication regularly (OR = 1.598, 95% CI: 1.173 – 2.177), and having a physical examination every year (OR = 1.578, 95% CI: 1.221 – 2.040); the results also revealed that male patients were less likely to have well-controlled blood pressure (OR = 0.762, 95% CI: 0.603 – 0.963) compared to female patients.

  Conclusion  Among 35 to 74 years old community hypertension patients in Luohu district of Shenzhen city, the blood pressure control rate was relatively high and was mainly influenced by gender, whether having local household registration, whether having antihypertensive medication regularly and whether taking a physical examination every year.
