Key result
Being divorced or widowed (OR 3.1, P=0.01) and a history of myocardial infarction (OR 0.41, P=0.04) predicted poor blood pressure control among 251 outpatients in South Africa.

Despite high rates of reported adherence and polypharmacy, blood pressure control remains sub-optimal in this South African outpatient cohort, with marital status and prior MI predicting poor control.
Low control rates and factor associations merit attention in outpatient care; hypothesis-generating and should not yet change practice.
OBJECTIVE: To determine the prevalence and factors associated with blood pressure (BP) control. METHODS: In a cross-sectional study involving 251 consecutively-sampled patients, a semi-structured questionnaire collected information on socio-demography, co-morbidities, hypertension treatments and BP control. Data analysis included descriptive statistics and logistic regression. RESULTS: Most participants were: on treatment for >5 years (60.6%); on three or more drugs (93.6%); treated according to guidelines (77%); and reported not missing medications in the last week (86.5%). BP control was achieved in only 31.5% and 16.7% of participants at the current and last visits, respectively. In multivariate regression analysis, a history of myocardial infarction (odd ratio [OR] = 0.41; P = 0.04) and being divorced/widowed (OR = 3.1; P = 0.01) predicted poor BP control. CONCLUSION: This study confirms the prevalent sub-optimal control of BP and suggests the need for further studies to examine the relationship between marital support, critical medical events and BP control.

Batubenga et al. (2015) conducted a cross-sectional in Hypertension (n=251). Divorced/widowed marital status and history of myocardial infarction vs. Other marital statuses and no history of myocardial infarction was evaluated on Poor blood pressure control (OR 3.1, p=0.01). Being divorced or widowed (OR 3.1, P=0.01) and a history of myocardial infarction (OR 0.41, P=0.04) predicted poor blood pressure control among 251 outpatients in South Africa.
