Hypertension is a pathology of high prevalence in the world. In Brazil, it is the main risk factor for the major cause of death in the country, coronary heart disease. The May Measurement Month Campaign in 2017 (MMM17) included a population with representation from all Brazilian states and reflects some of the characteristics of hypertension in Brazil. Questionnaire data were collected and three measures of blood pressure (BP) were performed. The sample consisted of 7260 individuals, 40% were white, 56.4% were women. The average age was 52 years. Diabetes was present in 11.9%, previous myocardial infarction in 4.0% and stroke in 2.7%. About 8.4% were smokers and 26.2% were users of alcoholic drinks. The average BMI was 26.9 kg/m2. Considering the means of the last two measures of BP 47.0% were hypertensive (>140/90 mmHg). Of the individuals who did not use medication, 19.5% were hypertensive and of those who used anti-hypertensive medication 40.0% were uncontrolled. Systolic BP increased with age. The use of alcohol was related to higher BP levels, as well as diabetes and obesity. The MMM17 campaign demonstrated a large number of unknown hypertensives and a high rate of uncontrolled hypertension in Brazil.
