Insights

The May Measurement Month Campaign in Brazil found that over two-thirds of participants had high blood pressure (hypertension). Many cases of hypertension remain undiagnosed, and a significant portion of treated patients have uncontrolled blood pressure.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Hypertension is a prevalent global health issue and the primary risk factor for coronary heart disease in Brazil.
  • The May Measurement Month Campaign (MMM18) aimed to assess hypertension prevalence and control across Brazil.
  • Previous findings from 2017 indicated significant challenges in hypertension management within the country.

Purpose of the Study:

  • To determine the prevalence of hypertension in a diverse Brazilian population.
  • To evaluate the proportion of undiagnosed and uncontrolled hypertension cases.
  • To analyze demographic and clinical factors associated with hypertension.

Main Methods:

  • A large-scale survey involving 12,413 participants from all Brazilian states.
  • Collection of questionnaire data on demographics, medical history, and lifestyle factors.
  • Performance of three blood pressure measurements per individual, with subsequent statistical analysis including multiple imputations.

Main Results:

  • An overall hypertension prevalence of 67.9% was identified (blood pressure >140/90 mmHg).
  • Among individuals not on medication, 27.9% were hypertensive; among those on medication, 40.3% had uncontrolled hypertension.
  • Systolic blood pressure showed a positive correlation with increasing age.

Conclusions:

  • The MMM18 campaign highlighted a substantial burden of undiagnosed hypertension in Brazil.
  • A high rate of uncontrolled hypertension persists, even among individuals undergoing treatment.
  • Urgent public health interventions are needed to improve hypertension detection and management in Brazil.

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Errors occurring during blood pressure monitoring01:25

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
