Epidemiology and control of hypertension and diabetes in Costa Rica.

Costa Rica is one of the countries that make up Central America, neighboring Nicaragua and Panama. Costa Rica shares with its neighbors the social and economic problems characteristic of developing countries; however, one difference is that Costa Rica can derive a great part of its budget and expense to health and education, as it had abolished the army in 1948. It is for this reason that Costa Rica shares diseases characteristic of their region like the Dengue, yet at the same time have a true explosion in the fields of hypertension (HTA), diabetes (DM), and cardiovascular disease. The health system of Costa Rica has nearly universal coverage, reaching 98% of the population with primary and secondary diverse levels of attention that give appropriate and satisfactory treatment to all hypertensive and diabetic patients. The HTA and the DM are true public health problems; however, before 2004, there weren't appropriate data on their prevalence and management. Small studies showed an increase in the prevalence of HTA from 9 to 24%, though no data on the prevalence of DM were available. In 2004, the Multinational Survey of Diabetes and Hypertension and Other Factors of Risk carried out in San José, Costa Rica, determined a prevalence of HTA of 25% and of DM of 8%. Likewise, the methodology of the survey allowed an evaluation of the quality of the attention of the HTA (Tracer of Arterial Hypertension) and, consequently, appropriate control of hypertensive patients in Costa Rica; through it, it was determined that greater effort was required for earlier detection and resource optimization to better handle hypertensive and diabetic patients and thus reduce cardiovascular morbidity-mortality and chronic renal disease.
