Assessment of hypertension management and control: a registry-based observational study in two municipalities in Cuba.

Background: To determine the prevalence of hypertension treatment and control among hypertensive patients in the Cuban municipalities of Cardenas and Santiago and to explore the main associated predictors.

Methods: Cross-sectional study, with multistage cluster sampling, conducted between February 2012 and January 2013 in two Cuban municipalities. We interviewed and measured blood pressure in 1333 hypertensive patients aged 18 years or older. Hypertension control was defined as blood pressure lower than 140/90 mmHg.

Results: The mean age ± standard deviation (SD) of participants was 59.8 ± 14 years, the mean systolic and diastolic blood pressure ± SD was 130.0 ± 14.4 and 83.1 ± 9.0 mmHg respectively. The majority of patients (91, 95%CI 90-93) were on pharmacological treatment, 49% with a combination of 2 or more classes of drugs. Among diagnosed hypertensive patients 58% (95%CI 55-61) had controlled hypertension. There was no association between hypertension control and gender, age and socio-economic condition. Levels of hypertension control depended on health area and control furthermore was positively associated with post-primary education, not being obese and white ethnicity: adjusted Odds Ratio (95% CI) 1.71 (1.26-2.34), 1.43 (1.09-1.88) and 1.41 (1.09-1.81) respectively.

Conclusions: The observed figures are outstanding at the international level and illustrate that hypertension treatment and control are achievable in a resource-constrained setting such as Cuba. The country's primary health care approach and social equity in access to health care can be seen as key determinants of this success. Nevertheless, there is still room for improvement, as over a third of patients did not have controlled hypertension.
