Ambulatory Blood Pressure Profiles And Correlation With Cardiovascular Risk Factors In A Sample Of 3

In this descriptive cross-sectional analysis, researchers examined the association between 24-hour ambulatory blood pressure (BP) monitoring (ABPM) profiles and cardiovascular risk factors vs clinic BP among Muhimbili University of Health and Allied Sciences employees. There were 390 employees who took part in this study, with a mean age of 40.5 ± 8.9 years. The mean office systolic and diastolic BP were found to be 126 ± 12 mmHg and 78± 13 mmHg, respectively, while the corresponding values for mean 24-hour ABPM were estimated to be 122± 14 and 75± 10 mmHg. For hypertension, the prevalence was estimated to be 23.1%. The prevalence of white coat hypertension was reported to be 16.2%, while the presence of masked hypertension and nocturnal non-dipping was noted in 11.5 and 66.7%, respectively. Male gender, age ≥ 40 years, family history of hypertension, central obesity, elevated cholesterol and uric acid concentrations were identified as independent associated factors of hypertension. Overall, stronger correlations with cardiovascular risk factors in this population were displayed by ABPM measurements vs office BP, and thus ABPM measurements likely to reflect true BP. High proportion of masked, white coat and nocturnal non-dipping was revealed by ABPM, therefore, the use of ABPM to identify these clinically essential BP profiles is supported.
