Incidence of hypertension in a prospective cohort study of adults from Porto, Portugal
BMC Cardiovascular Disorders, 2012
Background: During the past 30 years, Portugal has been described as one of the countries with highest median blood pressure levels in Europe, but the incidence of hypertension is unknown. The aim of this study was to estimate the incidence of hypertension, according to socio-demographic characteristics and lifestyles.

Aims. We aimed to describe the temporal trends of the mean blood pressure and prevalence of hypertension in studies that evaluated Portuguese adults. Methods. Pubmed was searched and 42 eligible studies were identifi ed. Reference screening and data extraction were conducted independently by two researchers. We fi tted linear regression models to compute ecological estimates of hypertension prevalence and mean blood pressure, adjusting for sex, age and signifi cant interaction terms. Results. Between 1990 and 2005, the prevalence of hypertension defi ned as blood pressure Ն 140/90 mmHg and/or drug treatment remained approximately constant in young adults and decreased in middle-aged and older adults, whereas the prevalence of self-reported hypertension increased 0.4% per year (95% confi dence interval 0.1 -0.7) overall. Between 1975 and 2005, mean systolic and diastolic blood pressures decreased in middle-aged and older adults, reaching a 32-mmHg decrease in systolic blood pressure among women at average age 70. Conclusion. The trends in the last decades show a decrease in blood pressure levels, probably attributable to increasing awareness and a higher treatment proportion. Although this absolute trend in blood pressure parallels the observed in other high income European countries, Portugal maintains its position above the mean levels in other Western settings.

Introduction: Cardiovascular disease is an important cause of death and disability worldwide, and hypertension is responsible for at least 45% of all deaths due to heart disease and 51% of deaths due to stroke. This study aimed to estimate and describe the distribution of prevalence, awareness, treatment and control of hypertension in the Portuguese population in 2015. Methods: A national survey using a representative sample of 4911 individuals residing in Portugal and aged between 25 and 74 years was implemented. Trained nurses performed a health interview and a physical examination, including blood pressure measurement (right arm, three measurements at 1-min intervals). The prevalence of hypertension was stratified by gender, age group, marital status, education, occupation and type of residential area. Associations between hypertension prevalence and sociodemographic factors were assessed using bivariate and multivariate Poisson regression.
Construct validity and reliability of the Brazilian version of Hypertension Knowledge-Level Scale
Revista gaúcha de enfermagem, 2021
Objective: To validate the construct and test the reliability of the Brazilian version of Hypertension Knowledge-Level Scale. Methods: Methodological research with 220 participants in a primary health care unit from Curitiba, Paraná. The data were collected with a social demographic questionnaire and the Brazilian version of the scale. The construct validity and reliability were assessed using Cronbach's Alpha, Pearson's Correlation and Analysis of Variance. The discriminant validity was verified comparing groups of people with hypertension and without, using T test. Results: Cronbach's Alpha was 0.74. The groups comparison showed that people with hypertension had better results (p<0,001). Pearson's Correlation showed that the questions measure different aspects of the same construct, justifying its organization in subdimensions. Conclusion: The Brazilian version of Hypertension Knowledge-Level Scale is a reliable instrument, which had its construct and criterion validated to measure knowledge about hypertension among Brazilian people. It can help health professionals with planning educative actions.
Knowledge about cardiovascular disease in Portugal
Revista portuguesa de cardiologia : orgao oficial da Sociedade Portuguesa de Cardiologia = Portuguese journal of cardiology : an official journal of the Portuguese Society of Cardiology, 2018
To characterize specific knowledge on cardiovascular disease, particularly stroke and myocardial infarction (MI), and its relationship with sociodemographic factors, health literacy and clinical history, among the Portuguese population. In a cross-sectional study conducted in 2012, a total of 1624 Portuguese-speaking residents of mainland Portugal, aged between 16 and 79 years, were assessed through face-to-face interviews using a structured questionnaire. Around 30% of participants were unable to estimate the risk of MI or stroke. On average, those who responded estimated that 34.2% and 35.6% of Portuguese will suffer a stroke or MI, respectively, during their lifetime. "Not smoking" (36.8%) and a "healthy diet" (32.8%) were identified as the most important behaviors for prevention of cardiovascular disease, and less than half of the participants responded that the most appropriate option in the presence of acute cardiovascular signs or symptoms was to call the ...

Background: Around 30% of Brazilian population is hypertensive. Brazilian's Family Health Strategy (FHS) is a community-based approach to provide primary health care and control chronic disease as hypertension. The aims of this pilot study were to study hypertension prevalence and awareness and to analyze the feasibility of FHS program with community healthy agents (CHA) to collect data about hypertensive subjects in Matao, Brazil. Methods: A cross-sectional study was conducted in subjects equal or older than 40 years old in a neighborhood belonging to FHS program. CHA were trained to collect data and to assess blood pressure (BP) with an automated device. Hypertension diagnosis was defined if systolic blood pressure ≥ 140 mm Hg or diastolic blood pressure ≥ 90 mm Hg or subject had previous use of hypertensive drug. Chi-square test and univariate logistic regression analysis were applied with significance level of 5% and a confidence interval of 95%. Results: In 625 subjects, hypertension prevalence was 68.8% and women (71.9%) were more hypertensive than men (63.2%) (P = 0.02). Prevalence of hypertension increased with age group, from 46.3% (40-49 years) to 82.5% (70-79 years) (P < 0.001). The overall prevalence of pre-hypertension was 40.1%: stage 1, 25.7% and stage 2, 17.0%. Hypertension awareness was 81.8% and 79.8% reported use of anti-hypertensive drugs. BP was not controlled in 61.8% and 67.7% of them was using anti-hypertensive drugs. CHA reported no difficulties to collect data and BP assessment with the automated device. Conclusion: We observed a high hypertension prevalence rate, awareness, and subjects with uncontrolled hypertension even with use of anti-hypertensive drugs. CHA from FHS program are a feasible option to BP control in future studies involving larger populations.

Hypertension is a common condition causing cardio and cerebrovascular complications. Portugal has one of the highest mortality rates from stroke and a high prevalence of hypertension. Systolic Blood Pressure (SBP) is an important risk factor for cardiovascular events (myocardial infarction and stroke) and premature mortality, particularly in the elderly population. The present study aims to estimate the prevalence of hypertension in a Portuguese population living in a coastal city and to identify some of its determinants (namely gender, age, the body mass index and physical activity frequency). A total of 91 adults who attended three pharmacies of a coastal city in the center of Portugal, between May and August of 2013 were evaluated. Attendants who reported to have diabetes or taking antihypertensive drugs in the 2 previous weeks were excluded from the study. Sociodemographic factors, BMI, habits of exercise and BP were assessed. Hypertension was defined as blood pressure ≥140/90 m...
