RESUMO

Objective: Hypertension is the major modifiable risk factor for cardiovascular diseases and most of hypertensive patients will require medication for the control of blood pressure. This study analyses the prevalence of self-reported hypertension and the utilization of antihypertensive agents by adults in São Paulo City, Brazil, according to socioeconomic and demographic variables. Methods: Analysis of data from the Health Survey of São Paulo City – ISA Capital, a cross-sectional, population-based survey conducted in 2003 with 1668 adults aged 20 years or over. To investigate the distribution of the main antihypertensive drug classes, utilization of generic drugs and information about how the drugs were obtained, individuals who self-reported hypertension were asked about any drug use for high blood pressure in the previous three days. Results: The prevalence of self-reported hypertension was 16.9%. Advanced age, lower education and not having a job were independently associated with hypertension. The consumption of antihypertensive drugs was 73.1%. Among those who took antihypertensive drugs 38.3% and 35.3%, respectively, obtained the medication from the Brazilian Public Health System (SUS) and used generics. Angiotensin-converting enzyme inhibitors (ACEi) (41.9%) and diuretics (24.6%) were the most used drugs utilized as monotherapy and the most used combinations were ACEi + diuretics (36.0%) and diuretics + beta-blockers (22.3%). Conclusions: The distribution of self-reported hypertension is not equal among different subgroups of the population. The equity in the delivery of antihypertensive drugs is an important component of treatment and control of hypertension and the SUS could perform it to the less advantaged people. The classes consumed do not agree fully with the hypertension guidelines.
