- Background: Hypertension is a key potentially modifiable risk factor for cardiovascular disease-the leading cause of death in the UK. Good blood pressure (BP) control reduces mortality; however, health inequalities may lead to variability in hypertension management.
Aim: To investigate health inequities related to ethnicity, sex, age, and socio-economic status in the treatment and control of BP in a large cohort of adult patients with hypertension.
Design and Setting: A cross-sectional cohort study of adults with hypertension registered with general practices in North East London on 1st April 2019.
Methods: Multivariable logistic regression was used to estimate associations of demographics and treatment intensity on the following hypertension management indicators: 1) BP recording in last 12 months, 2) BP on age-adjusted target, 3) BP on age-adjusted target and BP recorded in last 12 months.
Results: In total, 156,296 adults were included. Black/Black British ethnic groups were less likely to have controlled BP than White ethnic groups (OR 0.89, 95% CI = 0.86-0.92). Asian/Asian British ethnic groups were more likely to have controlled blood pressure (OR 1.29, 95% CI = 1.25-1.34). Ethnic differences in control could not be explained by the likelihood of having a recent blood pressure recording, nor by treatment intensity differences. Older adults were more likely to have controlled hypertension than younger patients.
Conclusion: Black/Black British and younger people are less likely to have controlled hypertension and may warrant targeted interventions. Possible explanations for these findings are presented and further research is needed on reasons for ethnic differences.
