ABSTRACT
BACKGROUND: Hypertension represents a major public health challenge globally, with a rising prevalence in China. This study aims to explore the factors shaping blood pressure (BP) control among hypertensive patients managed in community health centres (CHCs), with a particular emphasis on the association with age.
METHODS: This was a population-based, observational study that used healthcare records from CHC in Shenzhen, covering the period from 1 January 2000 to 8 October 2024. Univariate and multivariate logistic regression analyses were employed to assess the independent associations of various factors with BP control rate. Additionally, the study evaluated the relationship between age and BP control across six distinct age subgroups.
RESULTS: The study included 1 073 914 participants who met the eligibility criteria, with 955 415 (88.97%) patients achieving BP control. The median baseline age was 55.9 (IQR 18-109) years. Individuals aged 45 years and above demonstrated better BP control rates (46-55, OR 1.053, 95% CI 1.020 to 1.087; 56-65, OR 1.246, 95% CI 1.205 to 1.289; 66-75, OR 2.183, 95% CI 2.103 to 2.265; >75, OR 2.159, 95% CI 2.060 to 2.262). Among young adults aged 18-35 years, increasing age was consistently associated with poorer BP control across most subgroups. For the middle-aged groups (36-45 and 46-65 years), age had little impact on BP control. In the 66-75 years age range, older age was linked to better BP control in some groups.
CONCLUSION: The association between age and BP control varied across age groups. Hypertension management strategies should be tailored to address the unique needs of different age groups, geographical regions and targeted populations.
