Precision assessment of a hypertension prevalence survey

BACKGROUND

Population surveys are crucial for public policy planning and provide valuable representative data. In the health sector studies to identify and assess the prevalence of Arterial Hypertension (AH), a chronic non-communicable disease (NCD), along with its associated risk factors have been conducted.

OBJECTIVES

This study aims to assess the effectiveness of a population health survey in estimating the prevalence of arterial hypertension (AH) in the Sorocaba municipality between August 2021 and June 2023.

METHODS

The analyzed performance indicator is the precision (design effect - deff) of AH prevalence in adults (≥ 18 years) and their exposure to primary risk factors. The total sample included 1,080 individuals from the urban area, deemed sufficient to estimate a deff of 1.5. This cluster-based study utilized census sectors as clusters, with data collected through household interviews, standardized questionnaires, and measurements of blood pressure and biometric parameters. The deff calculation formula used was weighted variance / raw variance. The Research Ethics Committee approved this study, with registration CAAE 30538520-1-0000-5373.

RESULTS

The deff values ranged from 0.44 for chronic obstructive pulmonary disease to 1.63 for asthma, with a deff of 1.00 for AH prevalence.

CONCLUSION

The study demonstrated good precision in its results, with high receptivity and cooperation from participants. The cost-effectiveness of the research deemed appropriate. The technique of selecting households within clusters (census sectors) based on detailed mapping and demographic data from the Instituto Brasileiro de Geografia e Estatística (IBGE) proved to be practical and efficient, suitable for replication in other municipalities and for studying other NCDs.

Occurrence and preventability of adverse events in hospitals: a retrospective study

OBJECTIVES

to analyze the incidence of preventable adverse events related to health care in adult patients admitted to public hospitals in Brazil.

METHODS

observational, analytical, retrospective study based on medical records review.

RESULTS

medical records from 370 patients were evaluated, 58 of whom had at least one adverse event. The incidence of adverse events corresponded to 15.7%. Adverse events were predominantly related to healthcare-related infection (47.1%) and procedures (24.5%). Regarding the adverse event severity, 13.7% were considered mild, 51.0% moderate, and 35.3% severe. 99% of adverse events were classified as preventable. Patients admitted to the emergency room had a 3.73 times higher risk for adverse events.

CONCLUSIONS

this study's results indicate a high incidence of avoidable adverse events and highlight the need for interventions in care practice.

[Hypertension in female prisoners in Brazil: far beyond the biological aspects]

The scope was to estimate the prevalence of arterial hypertension (AHT) and associated risk factors among female prisoners. Data from the National Health Survey of the Female Prison Population and Prison Guards were used, investigating sociodemographic variables, prison characteristics, health behaviors and conditions. Information was collected through a self-administered questionnaire, and the magnitude of the association was estimated by the odds ratio and 95% confidence interval. Of the 1,327 prisoner participants, 24.4% were hypertensive, the majority were 31 years of age or older (54.6%), and 51.5% self-reported mixed race. After adjustment for associated risk factors in the bivariate analysis, a direct relationship between age and AHT was observed, in which age equal to/over 41 years was independently associated with a 7-fold greater chance of having AHT, compared to those under 25 years of age. Those who self-reported mixed race, had high cholesterol, were obese and were also independently associated with a higher prevalence of AHT. The greater the number of people with whom the inmate shares a cell was associated with a higher prevalence of AHT, but without a dose-response relationship. The conclusion drawn is that age, race, obesity, physical inactivity and stress are risk factors for AHT in female prisoners.

Health of female prisoners in Brazil

Abstract The majority of the women in prisons comes from the poorest strata of society with limited access to education, income and health services. This contributes to the fact that female prisoners have a higher burden of adverse health events than both male prisoners and women in general population We objectived to estimate the prevalence of different morbidities and risk factors among female prisoners in Brazil. A total of 1,327 women were recruited in this cross-sectional study. Data were collected using a using audio computer-assisted self-interviewing questionnaire, rapid antibody tests and physical examination. The higher prevalences was of syphilis, infection sexually disease, arterial hypertense, asthma, common mental disorders and severe physical violence. Regarding risk factors, 36.3% have good knowledge about HIV, 55.8% were smokers, 72.3% had ever used any illicit drug, 92.1% are sedentary and 92.1% maintained an unhealthy diet. Female prisoners are disproportionately affected by various adverse health conditions. There is a need for an effective surveillance system inside prisons for early diagnosis and treatment.

Determinants of self-reported hypertension among women in South Africa: evidence from the population-based survey

Background

Hypertension (HTN), characterized by an elevation of blood pressure, is a serious public health chronic condition that significantly raises the risks of heart, brain, kidney, and other diseases. In South Africa, the prevalence of HTN (measured objectively) was reported at 46.0% in females, nonetheless little is known regarding the prevalence and risks factors of self-reported HTN among the same population. Therefore, the aim of this study was to examine determinants of self-reported HTN among women in South Africa.

Methods

The study used data obtained from the 2016 South African Demographic and Health Survey. In total, 6,027 women aged ≥ 20 years were analyzed in this study. Self-reported HTN was defined as a case in which an individual has not been clinically diagnosed with this chronic condition by a medical doctor, nurse, or health worker. Multiple logistic regression models were employed to examine the independent factors of self-reported HTN while considering the complex survey design.

Results

Overall, self-reported HTN was reported in 23.6% (95% confidence interval [CI], 23.1–24.1) of South African women. Being younger (adjusted odds ratio [aOR], 0.04; 95% CI, 0.03–0.06), never married (aOR, 0.69; 95% CI, 0.56–0.85), and not covered by health insurance (aOR, 0.74; 95% CI, 0.58–0.95) reduced the odds of self-reported HTN. On the other hand, being black/African (aOR, 1.73; 95% CI, 1.17–2.54), perception of being overweight (aOR, 1.72; 95% CI, 1.40–2.11), and perception of having poor health status (aOR, 3.53; 95% CI, 2.53–5.21) and the presence of other comorbidities (aOR, 7.92; 95% CI, 3.63–17.29) increased the odds of self-reported HTN.

Conclusions

Self-reported HTN was largely associated with multiple sociodemographic, health, and lifestyle factors and the presence of other chronic conditions. Health promotion and services aiming at reducing the burden of HTN in South Africa should consider the associated factors reported in this study to ensure healthy aging and quality of life among women.

Twenty-year Follow-up of Patients With Epidemic Glomerulonephritis due to Streptococcus zooepidemicus in Brazil

Introduction

Post-streptococcal glomerulonephritis (PSGN) has a good prognosis in children, but few studies have evaluated the long-term renal outcomes in adults with PSGN.

Methods

In a follow-up study, 47 predominantly adult patients with PSGN due to group C Streptococcus zooepidemicus were reassessed 20 years after an outbreak in Nova Serrana, Brazil. We evaluated clinical characteristics, renal outcomes, and the trajectory of the estimated glomerular filtration rate (eGFR) by the creatinine-based chronic kidney disease-epidemiology collaboration equation from 5 follow-up assessments. Logistic regression and mixed-effects regression were used in the analysis.

Results

After 20 years, the participants’ mean age was 56.6±15.1 years. Thirty-four (72%) patients had hypertension, 21 (44.7%) had eGFR <60 ml/min per 1.73 m², 8 of 43 (18.6%) had urine protein-to-creatinine ratio >150 mg/g, and 25 (53%) had CKD (low eGFR and/or increased proteinuria). Increasing age was associated with CKD (odds ratio: 1.07; 95% confidence interval [CI]: 1.02–1.13; P = 0.011) in multivariate analysis. The mean eGFR decline in the last 11 years of follow-up was −3.2 ml/min per 1.73 m² per year (95% CI: −3.7 to −2.7). Older age at baseline (coefficient −1.05 ml/min per 1.73 m² per year; 95% CI −1.28 to −0.81; P < 0.001), and hypertension 5 years after the outbreak (coefficient −7.78 ml/min/1.73 m²; 95% CI −14.67 to −0.78; P = 0.027) were associated with lower eGFR during the whole study period.

Conclusion

There was a marked worsening of renal function and a high prevalence of CKD and hypertension after 20 years of PSGN outbreak. Long-term follow-up is warranted after PSGN, especially among older patients.

Variabilidade da Pressão Arterial em Única Visita e Risco Cardiovascular em Participantes do ELSA-Brasil

Fundamento

A variabilidade da pressão arterial (VPA) tem valor prognóstico para desfechos cardiovasculares fatais e não fatais.

Objetivos

Este estudo teve como objetivo avaliar a associação entre a VPA em uma única visita e o risco cardiovascular em participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil).

Métodos

O presente estudo transversal foi conduzido com dados basais (2008-2010) de 14.357 participantes do ELSA-Brasil, sem história de doença cardiovascular. A VPA foi quantificada pelo coeficiente de variação de três medidas padronizadas da pressão arterial sistólica (PAS) realizadas com um oscilômetro. Medidas antropométricas e exames laboratoriais também foram realizados. O risco cardiovascular foi avaliado pelo estimador de risco de doença cardiovascular aterosclerótica (ASCVD), e se empregou a análise de regressão logística multivariada com nível de significância de 5%.

Resultados

Um risco cardiovascular significativamente maior foi determinado por uma VPA elevada para ambos os sexos. Uma prevalência significativamente maior de alto risco foi observada mais em homens que em mulheres em todos os quartis, com a maior diferença observada no quarto quartil de variabilidade (48,3% vs. 17,1%). Comparações entre quartis por sexo revelaram um risco significativamente mais alto para homens no terceiro (OR=1,20; IC95%: 1,02 - 1,40) e no quarto quartis OR=1,46; IC95%: 1,25 -1,71), e para mulheres no quarto quartil (OR=1,27; IC95%: 1,03 - 1,57).

Conclusão

Análises de dados basais de participantes do ELSA-Brasil revelaram que a variabilidade da pressão arterial se associou com risco cardiovascular aumentado, especialmente nos homens.

Body mass index is superior to other body adiposity indexes in predicting incident hypertension in a highly admixed sample after 10-year follow-up: The Baependi Heart Study

Hypertension is the leading cause of overall mortality in low- and middle-income countries. In Brazil, there is paucity of data on the determinants of incident hypertension and related risk factors. We aimed to determine the incidence of hypertension in a sample from the Brazilian population and investigate possible relationships with body adiposity indexes. We assessed risk factors associated with cardiovascular disease, including adiposity body indexes and biochemical analysis, in a sample from the Baependi Heart Study before and after a 10-year follow-up. Hypertension was defined by the presence of systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg or the use of antihypertensive drugs. From an initial sample of 1693 participants, 498 (56% women; mean age 38 ± 13 years) were eligible to be included. The overall hypertension incidence was 24.3% (22.3% in men and 25.6% in women). Persons who developed hypertension had higher prevalence of obesity, higher levels for blood pressure, higher frequency of dyslipidemia, and higher body adiposity indexes at baseline. The best prediction model for incident hypertension includes age, sex, HDL-c, SBP, and Body Mass Index (BMI) [AUC = 0.823, OR = 1.58 (95% CI 1.23-2.04)]. BMI was superior in its predictive capacity when compared to Body Adiposity Index (BAI), Body Roundness Index (BRI), and Visceral Adiposity Index (VAI). Incident hypertension in a sample from the Brazilian population was 24.3% after 10-year follow-up and BMI, albeit the simpler index to be calculated, is the best anthropometric index to predict incident hypertension.

Risk of all-cause mortality and its association with health status in a cohort of community-dwelling older people: FIBRA study

This article aims to estimate the risk of death according to sociodemographic characteristics, chronic diseases, frailty, functional capacity, and social participation in older people as well as determine the median time of death in relation to health status and social participation. A retrospective longitudinal study was conducted with older people (≥65 years) in 2008-09 and 2016-17 in the city of Campinas and the subdistrict of Ermelino Matarazzo in the city of São Paulo. Face-to-face interviews were conducted at community centers and the participants' homes. The cumulative incidence of death was estimated and associations with the predictor variables were analyzed using Poisson multiple regression. The Kaplan-Meier method and the log-rank test were also used. Among the 741 individuals located at follow-up, 192 had deceased. The incidence of death was higher among those who reported having heart disease and those who were dependent on others regarding the performance of instrumental activities of daily living. The incidence of death was lower among women, individuals in the highest income stratum, and those who performed three or more activities related to social inclusion. No differences in median survival times were found. Predictors of mortality can contribute to broadening knowledge on the singularities of the aging process.

Impact of the Health Gym Program on mortality from Systemic Arterial Hypertension in Pernambuco state, Brazil

The aim of this paper was to analyze the impact of the Health Gym Program (HGP) on the Systemic Arterial Hypertension mortality rate in Pernambuco state, Brazil. This public policy impact analysis used a quasi-experimental approach which consisted of the application of Propensity Score Matching in the years 2010 and 2017. Socioeconomic, demographic, and epidemiological data of 89 municipalities that implemented HGP (treated) and 54 that did not (controls) were collected from the Brazilian Health Data Department, Brazilian Institute of Geography and Statistics, and other databases. The impact of HGP on hypertension mortality rate was estimated through a logit model using the Kernel algorithm. Treated municipalities presented a decrease of 12.8% in global hypertension mortality rate, 12.5% in brown-skinned people and 13.1% in those over 80 years of age. The balancing test attests to the robustness of the estimated model to explain the impact of the program on mortality due to hypertension. The implementation of the program proved to be effective in decreasing the mortality rate in the treated municipalities, indicating that it seems to contribute to controlling the progress of chronic non-communicable diseases.

Coping with Hypertension among Indigenous Peoples in Brazil and the Role of the Primary Care Nurse: A Critical Review from a Transcultural Perspective

Our objective is to critically review the literature addressing the strategic role of nurses in the daily primary care of arterial hypertension in Indigenous communities in Brazil. We selected studies based on an initial keyword search of major bibliographic indexing databases for the years 2000 to 2020 and manual search. Further selection was based on topical, methodological, and thematic relevance, as well as evaluation of scholarship quality and pertinence to our chosen narrative. The literature demonstrates Indigenous peoples do not receive health services that measure up to national standards in large part due to a marked lack of academic and employer preparation for nurses operating in transcultural settings. Inequities were apparent in recurrent reports of victim-blaming, deficient clinical communication with patients, clinical malpractice, devaluation of hypertension as a problem for Indigenous peoples, insufficient intercultural training for nurses, and discrimination against Indigenous students in nursing education programs. This systemic problem needs to be addressed by universities and the Indigenous Health Care Subsystem in Brazil.

A RELAÇÃO ENTRE HIPERTENSÃO ARTERIAL, ANSIEDADE E ESTRESSE: UMA REVISÃO INTEGRATIVA DA LITERATURA

  Este estudo teve por objetivo realizar uma revisão integrativa de literaturapara verificar o que os estudos têm abordado sobre a relação entre estresse e ansiedade em pessoas hipertensas. Para tanto, o levantamento dos estudos foi realizado nas bases PsycINFO, Portal da Capes, Scielo e Medline BVS-PSI, utilizando os descritores ‘hipertensão arterial’ and ‘estresse’ and ‘ansiedade’, e seus correspondentes na língua inglesa ‘arterial hypertension’ and ‘stress’ and ‘anxiety’ e espanhola ‘hipertensión’and ‘estrés’ and ‘ansiedad’, considerando os últimos seis anos (2013 a 2018). Foram selecionados 14 estudos. Os resultados foram agrupados em três categorias: a) o impacto causado pelo diagnóstico de doenças crônicas não transmissíveis, b) fatores psicológicos associados à hipertensão arterial e c)relação saúde física versus saúde mental: uma questão também de método. Os resultados mostraram que ansiedade e estresse, além da depressão podem apresentar-se como aspectos moduladores da hipertensão arterial. Portanto, considera-se necessária a desmistificação da lógica cartesiana entre mente e corpo, para que sejam efetivadas ações de cuidado integral dos sujeitos e de promoção à saúde. Espera-se que os resultados obtidos reafirmem a importância de considerar os aspectos psicológicos e emocionais nas doenças crônicas e que estudos futuros com diferentes delineamentos sejam desenvolvidos na área da psicologia.

Trends in the prevalence of systemic arterial hypertension and health care service use in Brazil over a decade (2008-2019)

The global burden and the prevalence of systemic arterial hypertension (SAH) have increased over the last two decades, especially in low- and middle-income countries, and are a concern to health authorities. This study analyzed the prevalence of SAH reported by Brazilian adults in 2008, 2013, and 2019, and individual disease control in 2013 and 2019. Data from the National Household Sample Survey (2008) and National Health Survey (2013-2019) were employed. We calculated the disease's prevalence ratios using Poisson regression, adjusted for sociodemographic characteristics. Regarding health care and PHC organization indicators, we calculated proportions by gender, age group, ethnicity, and region. The results reveal persistent regional inequalities, with lower prevalence in the North and Northeast and higher prevalence in the Southeast and South. While the health care access and use indicators are positive, reflecting PHC improvements in recent years, we highlight the importance of adopting multifaceted SAH prevention and control strategies in the country.

Contraception use and family planning inequalities among Brazilian women

BACKGROUND

Brazil has shown a considerable decline in fertility rates in recent decades. However, sociodemographic differences still have a direct impact on access to family planning in the country.

OBJECTIVE

To estimate the prevalence of contraceptive use according to sociodemographic variables among Brazilian women in reproductive age.

METHODS

A cross-sectional study conducted with 17,809 women who have responded to the National Health Survey. We estimated the prevalence as well as the 95% confidence intervals and we used Pearson's chi-square test at a significance level of 5% to analyze differences between groups.

RESULTS

More than 80% of the women reported to use some contraception method, the most used method was oral contraceptive (34.2%), followed by surgical (25.9%) and condoms (14.5%). Black/Brown, northerly, and low-educated women are more frequently sterilized, while white women, with higher schooling and those living in the south and southeast are the ones who use oral contraception and double protection the most.

CONCLUSION

Despite the observed improvements, there was no decrease in the prevalence for not using any CM and there are inequalities in access to contraception in the country.

Distribution and spatial autocorrelation of the hospitalizations for cardiovascular diseases in adults in Brazil

OBJECTIVES

To analyze the distribution and spatial autocorrelation of the hospitalization rates for cardiovascular diseases in adults, and to verify the correlation with socioeconomic and health factors in Brazil.

METHODS

An ecological study of hospitalization rates for cardiovascular diseases in adults from 2005 to 2016. Spatial dependence was analyzed by the Moran Global and Local autocorrelation coefficients. The correlation between hospitalization rates and socioeconomic and health variables was calculated using the Spearman's correlation coefficient.

RESULTS

The highest hospitalization rates were observed in the states of Santa Catarina, Paraná, São Paulo, and Mato Grosso, with high-high autocorrelation clusters for ischemic heart disease. The hospitalizations for cardiovascular diseases were strongly correlated with low schooling, alcohol consumption, and diagnosis of hypertension.

CONCLUSION

The high rates of hospitalization in the states mentioned, linked to socioeconomic and health factors, suggest public policies focused on the theme.

Hipertensión arterial autorreferida en adultos mayores brasileños: uso de medicación y recomendaciones para el control

Objetivo Estimar la prevalencia de hipertensión arterial (HA) autorreferida y del uso de medicación en los adultos mayores brasileños (≥65 años), según las características sociodemográficas, y evaluar el uso de los servicios de salud y de las recomendaciones de los médicos y profesionales de salud para el control de la enfermedad. Método Estudio transversal con datos de la Pesquisa Nacional de Salud del 2013 (n=7.712). Resultados La prevalencia de HA fue del 54,1%, con diferencia entre los sexos. En los hombres, la prevalencia de HA fue mayor en las regiones Sur y Sudeste, y en las mujeres fue mayor en los subgrupos de 75 a 79 años y de menor escolaridad. El uso de medicación para la HA fue mencionado por el 91,7%, sin diferencia entre los sexos. Las mujeres fueron diagnosticadas con más precocidad (≤39 años) que los hombres (≥65 años). Conclusión El mantenimiento de una alimentación saludable y el consumo reducido de sal se observaron con mayor frecuencia en las mujeres. Los resultados destacan la necesidad de intervenciones para promover el autocuidado, sobre todo entre los hombres.

Clinical indicators and aetiological factors of sedentary lifestyle in patients with arterial hypertension

AIMS

The aim of this study is to verify the clinical validity of clinical indicators and aetiological factors of sedentary lifestyle in individuals with arterial hypertension.

BACKGROUND

Diagnostic validation is performed to expand nursing taxonomies and to revise or confirm the described concepts. New elements listed in the literature and those identified by the NANDA International definition for sedentary lifestyle need to be evaluated.

DESIGN

This is a cross-sectional and diagnostic validation study. The STROBE guidelines were used in this study.

METHODS

Two hundred and fifty subjects aged over 18 years were evaluated. The diagnostic status of the participants was obtained by latent class analysis. Logistic regression was used to identify aetiological factors with the manifestation of sedentary lifestyle, considering a significance level of 5%.

RESULTS

A total of 57.8% of the study participants met the diagnostic criteria for sedentary lifestyle. The clinical indicators with high sensitivity were as follows: "Average daily physical activity is less than recommended for gender and age"; "Does not perform physical activity during leisure time"; "Preference for activity low in physical activity" and "Overweight." The significantly related factors associated with the diagnosis of sedentary lifestyle were as follows: "Insufficient knowledge on physical activity," "Lack of time," "Negative self-perception of health," "Lack of security," "Lack of appropriate place," "Lack of motivation," "Activity intolerance," "Lack of sports ability," "Having a partner," "Using public transportation," "Perception of physical disability," "Pain," "Having a job/studying," "Laziness," "Impaired mobility," "Living in an urban area," "Education in a public institution," "Female gender," "Lack of confidence to practice physical exercise," "Education level," "Age" and "Lack of social support for the practice of physical exercise."

CONCLUSION

Four out of eight clinical indicators had a good adjustment by the latent class analysis. Of the 27 aetiological factors, 22 were significantly associated with sedentary lifestyle.

RELEVANCE TO PRACTICE

The correct identification of sedentary lifestyle and its elements supports care planning, especially for health promotion and disease prevention.

Vulnerabilidade da população negra brasileira frente à evolução da pandemia por COVID-19

Introdução: Devido as iniquidades históricas, o contexto pandêmico do COVID-19 tem impactado de maneira distinta os segmentos sociais, exigindo um acompanhamento especial às minorias étnico-raciais que vivem em situação de vulnerabilidade. Nesse sentido, o estudo tem como objetivo analisar a vulnerabilidade da população negra brasileira frente à evolução da pandemia por COVID-19. Materiais e Métodos: Trata-se de um estudo documental, descritivo, quantitativo, realizada a partir dos boletins epidemiológicos coronavírus publicados pelo Ministério da Saúde do Brasil. Foram avaliadas duas variáveis dos boletins epidemiológicos coronavírus a partir da raça/cor: hospitalizações por síndrome respiratória aguda grave e óbito por Covid-19. Resultados: Entre os boletins nº 9 e nº 18 evidenciou-se o aumento sustentado nas taxas de internação por síndrome respiratória aguda grave (de 23,9% para 54,7%) e óbito (de 34,3% para 61,3%) entre pessoas de raça/cor negra e redução constante na hospitalização (de 73% para 43,3%) e óbito (de 62,9% para 36,5%) entre pessoas brancas. Constata-se que pessoas negras têm maiores chances de internação por SRAG e morte por COVID-19 no Brasil, o que implica maior situação de vulnerabilidade. Discussão: Acredita-se que esse cenário desfavorável entre pessoas negras se deve a dificuldade ou impossibilidade de realização de isolamento social, à prevalência de comorbidades que precipitam quadros graves do COVID-19, as dificuldades no acesso aos serviços de saúde e ao racismo institucional. Conclusão: faz-se necessário a implementação de uma rede de proteção social a esse grupo racial, com o objetivo de reduzir o acometimento da doença e a letalidade do vírus.

Demographic and socioeconomic characteristics of Brazilian adults and COVID-19: a risk group analysis based on the Brazilian National Health Survey, 2013

This study aimed to characterize risk groups for COVID-19 in Brazil and to estimate the number of individuals living in the same household with persons in the risk group. Data were used from the Brazilian National Health Survey (PNS) of 2013. To characterize the risk groups, a binary multiple logistic regression model was adjusted in which the response variable was the presence or absence of at least one condition associated with COVID-19 and the explanatory variables were age, sex, major geographic region, color or race, schooling, and workforce status of the residents interviewed by the study. The results show that age is the principal risk factor for comorbidities associated with COVID-19, but the risk is also greater for persons in more vulnerable categories, such as those with less schooling and blacks and browns. An estimated 68.7% of Brazilians were living with at least one person in the risk group: 30.3% lived with at least one elderly individual and another 38.4% had no elderly individuals in their households, but there was at least one adult resident with preexisting medical conditions. The proportion of persons living in households with at least one resident in the risk group was 50% or greater for all ages and increased from 35 years of age, but there were also high numbers of persons 10 to 25 years of age living with persons in the risk group. The results suggest that due to the difficulties in avoiding close household contact, the exclusive isolation of specific population groups is not a feasible strategy in the Brazilian context, but should be combined with social distancing of the population as a whole.

Treatment adherence and frailty syndrome in hypertensive older adults

OBJECTIVE

To analyze the association between adherence to antihypertensive treatment and frailty syndrome in hypertensive older adults.

METHOD

A descriptive, cross-sectional study with a quantitative approach with older adults. The data collection took place between November 2017 and March 2018, evaluating sociodemographic information, adherence to antihypertensive treatment, lifestyle and frailty through the Edmonton Frail Scale. The Kruskal-Wallis test and the Chi-squared test were used for data analysis, considering a 95% confidence interval and a significance level of p<0.05.

RESULTS

There were 193 older adults who participated in the study. The average age was 80.94 (sd ± 7.17) years, with a predominance of females (72%) and widows (43.5%). The factors which were associated with adherence to treatment were diastolic blood pressure, education and the time that the older adult had smoked (p<0.05). Frailty was not associated with treatment adherence levels (p=0.095).

CONCLUSION

There was no association between frailty scores and control of arterial hypertension; however, adequate monitoring and nursing care are essential in assessing adherence to treatment in order to reduce the aggravations of the disease and frailty syndrome development.

Prevalence and Risk Factors for Self-Report Diabetes Mellitus: A Population-Based Study

The aim of this study was to estimate the prevalence and risk factors for self-reported diabetes mellitus (DM) in the adult population of the Central-West region of Brazil. In 2013, a cross-sectional study using the data from the National Health Survey and comprising 7519 individuals aged ≥18 years from the Central-West region was conducted. Participants were interviewed at their homes about sociodemographic data and risk factors for DM. To verify the risk factors with DM, the Poisson regression model was used. The analyses were performed for the total sample and stratified according to sex. The prevalence of DM was 6.5% (95% confidence interval [95% CI], 5.7–7.3). The diagnosis of self-reported DM was 4.3% in men and 7.5% in women. In the global sample, it was found that age between 40–59 years and ≥60 years, previous smoking (former smoker), self-reported hypertension, self-reported dyslipidemia, overweight, and obesity were independently associated with self-reported DM. In men, risk factors were: Age ≥ 60 years, self-reported hypertension, self-reported dyslipidemia, and obesity. In women, risk factors were: Age 30–39 years, 40–59 years, and ≥60 years, previous smoking (former smoker), self-reported hypertension, self-reported dyslipidemia, overweight, and obesity. Conclusion: The prevalence of DM was 6.5%. DM was associated with advanced age; previous smoking (former smoker), hypertension, dyslipidemia, overweight, and obesity. Some differences in risk factors between men and women were noted.

RESUMO Trata-se da avaliação de um programa de prevenção e tratamento de Doenças Crônicas Não Transmissíveis (DCNT) oferecido à comunidade de uma universidade pública por ambulatório localizado em suas dependências. O processo avaliativo teve como objetivo apreender a dinâmica e compreender a forma de interação entre os atores envolvidos no cotidiano do programa, partindo do entendimento dos seus grupos de interesse, formados pela equipe, usuários, gestores e profissionais encaminhadores. Realizou-se pesquisa qualitativa de caráter participativo e com dimensão formativa para ampliar a possibilidade de aperfeiçoamento do programa pelos sujeitos envolvidos a partir de elementos oriundos de sua prática. A Avaliação de Quarta Geração de Guba e Lincoln e o Método Paideia de Campos foram norteadores metodológicos da pesquisa. A análise do material empírico foi agrupada em três núcleos temáticos: método de trabalho, equipe e gestão do programa. Constatou-se que uma escuta reflexiva dos profissionais é fator decisivo para ampliar a autonomia dos usuários e sua adesão terapêutica; a realização de grupos educativos no local de trabalho favoreceu a captação para tratamento e participação dos usuários, especialmente os do gênero masculino; e os encontros dos grupos possibilitam diversos ganhos objetivos e subjetivos, como a interação social entre pessoas de diferentes áreas da universidade.

Factors associated with not adopting healthy behavior among hypertensive individuals: a population-based study in Brazil

Adoption of a healthy lifestyle is strongly recommended for the control of hypertension, but professional advice alone does not ensure uptake of healthy behavior. Therefore, this study aimed to investigate the factors-associated with non-adoption of healthy behaviors among individuals with a medical diagnosis of hypertension. It was a cross-sectional study using data from the National Health Survey (PNS) carried out in Brazil in 2013, based on interviews with adults (≥18 years) (n = 60,202). The outcome variable was the non-adoption-two or fewer-of healthy behaviors (regular physical activity, recommended consumption of fruit and vegetables, no excessive alcohol consumption, no smoking, and very low/low salt intake [self-perceived]). A logistic regression model was used to verify the factors-associated with non-adoption of healthy behaviors. Approximately 64% of the study sample did not adopt healthy behaviors, i.e., they adopted two or fewer healthy habits. The most frequently mentioned healthy behaviors were not drinking excessively (91.5%), followed by not smoking (86%). Short time since disease diagnosis (OR = 1.20, 95% CI: 1.01-1.43), not using antihypertensive medication (OR = 1.38, 95% CI: 1.13-1.68), not making regular doctor visits (OR = 1.43, 95% CI: 1.23-1.65), and good self-rated health (OR = 1.16, 95% CI: 1.01-1.36) increased the chance of individuals not adopting healthy behaviors compared with their respective reference categories, independently of gender, age, schooling, and economic status. Counseling strategies should consider patient particularities, and health professionals need to be aware of issues that can interfere with the adoption of healthy behaviors of hypertensive patients.

Reasons for non-vaccination against influenza among older adults with hypertension in Brazil: a cross-sectional study

The aim of this study was to estimate the prevalence of non-vaccination against influenza among Brazilian older adults with systemic arterial hypertension and determine the main reasons for non-adherence. A cross-sectional study was conducted using data from older adults (≥ 60 years of age) with hypertension who participated in the 2013 National Health Survey and reported not having been vaccinated against flu over the previous 12 months (n = 1,295). The analyses were performed using the Stata 14.0 software. The data were weighted because of the sampling design. An estimated 3,026,080 older adults with hypertension had not received a flu vaccine over the 12 months prior to the survey (22.6%). No significant associations were found with sex, age group or schooling. The prevalence of unvaccinated older adults was lower in the southern and southeastern regions of Brazil than in the northern and northeastern regions, even after adjusting for age. The prevalence was higher among individuals without private health insurance. The main reasons for non-vaccination were fear of a reaction, rarely having the flu and not believing in the protection of the vaccine. The present findings underscore the need for healthcare professionals to explain to the population the benefits of the vaccine for preventing severe influenza (protective effect and possible reactions) and for secondary prevention of cardiovascular events. Increasing the prevalence of vaccination in older adults with hypertension and other cardiovascular diseases is of fundamental importance within the realm of public health as a strategy for reducing occurrences of complications and deaths associated with influenza.

[Factors associated with arterial hypertension: a systematic review]

A systematic review of demographic, socioeconomic, behavioral and anthropometric factors associated with hypertension. We included observational studies, of populations aged 18 or older, from the past ten years, published in English, Portuguese or Spanish from Pubmed, Web of Science, Scopus and Lilacs bases. The most found factors related to the greater chance of having hypertension were age and the Body Mass Index (BMI). Other factors associated with the disease were: gender (male), education (lower education), income (lower income) and waist circumference (high). Never having smoked, never having consumed alcohol and white skin color were characteristics related to a lower chance of having hypertension. As demonstrated, demographic, socioeconomic, behavioral and anthropometric characteristics are important factors associated with a greater chance of having hypertension in the adult population. However, while most of the factors associated with it are amenable to intervention, broader health promotion policies will be needed to reduce socioeconomic inequalities in the prevalence of the disease.

Hypertension in Workers: The Role of Physical Activity and its Different Dimensions

BACKGROUND

Physical activity, each type in its own manner, whether occupational, domestic or leisure, can play a significant role regarding high blood pressure (HBP). However, practicing physical activity only at leisure time, or in specific situations, can be insufficient to achieve the effective control of HBP.

OBJECTIVE

To analyze the isolated and cumulative effect of different types of physical activity and the prevalence of HBP among workers.

METHODS

A cross-sectional study with 1,070 Urban Cleaning and Footwear Industry workers in Bahia, who answered a survey, conducted by an interviewer on sociodemographic, occupational, lifestyle and hypertensive morbidity aspects. Weight, height, waist circumference and blood pressure were measured. Case of HBP: Systolic blood pressure ≥140 or diastolic blood pressure ≥90, or regular treatment for HBP. The occupational, domestic and leisure aspects of Physical Activity were studied. A multivariate analysis with Cox Regression was performed for cross-sectional studies.

RESULTS

The prevalence of HBP was 24%, being 37% among workers aged between 35-44 years, and 51% among workers aged between 45-54 years. The multivariate model showed that workers who were active in one form of physical activity only or no forms had 62% higher BP levels and that these levels were 25% higher among workers who were active in two out of three physical activity forms. Being a male, being older (> 31 years old) and being overweight were characteristics associated with HBP, with prevalence ratios of 1.62, 2.10 and 2.26, respectively.

CONCLUSIONS

There was a cumulative effect of the form of physical activity on the occurrence of HBP. Classifying active subjects at work or at home as inactive persons by relying only on the leisure form can lead to methodological errors. (Arq Bras Cardiol. 2020; 114(5):755-761).

Abordagem dietética para controle da hipertensão: reflexões sobre adesão e possíveis impactos para a saúde coletiva

Resumo A dieta DASH (Dietary Approach to Stop Hypertension) é considerada um padrão alimentar saudável, sendo preconizada para o controle da hipertensão arterial. O objetivo do artigo foi revisar a literatura sobre a dieta DASH e verificar sua adesão pela população brasileira. Realizou-se revisão integrativa nas bases Medline/PubMed, SciELO e LILACS, nos idiomas inglês e português. A literatura sobre dieta DASH é extensa, entretanto quatro estudos mostrando a adesão pela população brasileira foram encontrados. A dieta DASH representa uma intervenção potencialmente acessível e aplicável que poderia melhorar a saúde da população. Os estudos diferiram entre si nos métodos de avaliação utilizados e a baixa adesão evidencia a necessidade de implementação de ações no âmbito da atenção nutricional ao hipertenso. Estratégias inovadoras serão necessárias para determinar a melhor forma de minimizar as barreiras para disseminação e adesão a esse padrão alimentar saudável. Sugere-se planos alimentares e orientações flexíveis, pouco restritivas, compatíveis, com objetivos claros, direcionados para mudanças graduais, com monitoramento frequente de equipe multiprofissional de saúde.

The influence of the Family Health Strategy on hypertensive adults in health care use in Brazil

INTRODUCTION

Systemic arterial hypertension (SAH) has a high prevalence in Brazil and impacts on the use of health services.

OBJECTIVE

This study verified the influence of the Family Health Strategy (FHS) on the use of health services by adults ≥ 18 years old who reported SAH in the National Health Survey (Pesquisa Nacional de Saúde - PNS) 2013.

METHODS

The Propensity Score (PS) method was used to correct the lack of homogeneity between the groups with SAH under exposed or not to the FHS. PS was estimated using binary logistic regression, which reflected the conditional probability of receiving the household register in the FHS according to socioeconomic, demographic and health covariates of adults and their families. After estimating the PS, the stratification was used to group hypertensive adults into five mutually exclusive strata (pairing them). Prevalence and confidence intervals at 95% were estimated of medical consultations and hospitalizations. The effects of the complex NHS sampling were incorporated into all phases of the analysis.

RESULTS

It was verified that hypertensive adults enrolled in FHS had worse socioeconomic, health and health conditions, but similar prevalence of medical consultations and hospitalizations to adults without a FHS registry and with better living and health conditions. The FHS has attenuated individual and contextual inequalities that impact the health of Brazilians by favoring the use of health services.

CONCLUSION

The FHS can favor the care and control of SAH in Brazil. Thus, it must receive investments that guarantee its effectiveness.

Epidemiological analysis of 1404 patients with intracranial aneurysm followed in a single Brazilian institution

Background:

We sought to evaluate the epidemiology of intracranial aneurysms in relation to location, gender, age, presence of multiple aneurysms, and comorbidities in the Brazilian population.

Methods:

We performed a prospective analysis of a cohort of 1404 patients diagnosed with intracranial aneurysm admitted to the Hospital das Clinicas of the University of Sao Paulo, a referral hospital for the treatment of cerebrovascular diseases in Brazil. Patients admitted between September 2009 and September 2018 with radiological diagnosis of intracranial aneurysm were included in the study.

Results:

A total of 2251 aneurysms were diagnosed. Females accounted for 1090 aneurysms (77.6%) and the mean age at diagnosis was 54.9 years (ranging 15–88). The most common location was middle cerebral artery (MCA) with 593 aneurysms (26.3%) followed by anterior cerebral artery (ACA) with 417 aneurysms (18.5%) and internal carotid artery in the posterior communicating segment with 405 aneurysms (18.0%). Males had higher rates of ACA aneurysms (29.7%) while females had higher rates of MCA aneurysms (26.1%). Sorting by size, 492 aneurysms were <5 mm (21.8%), 1524 measured 5–10 mm (67.7%), 119 size 11–24 mm (5.3%), and 116 were >24 mm (5.2%). The occurrence of multiple aneurysms was associated with female gender (P < 0.001) and smoking (P < 0.001), but not with hypertension (P = 0.121).

Conclusion:

In this population, the occurrence of intracranial aneurysm is related to several factors, including gender, age, smoking, and hypertension. Our study brought to light important characteristics of a large number of Brazilian patients regarding epidemiology, location, size, and multiplicity of intracranial aneurysms.

Pressão arterial não controlada entre pessoas idosas hipertensas assistidas pela Estratégia Saúde da Família

Resumo Objetivo Investigar a prevalência de pressão arterial (PA) não controlada e fatores associados em pessoas idosas hipertensas assistidas pela Estratégia Saúde da Família em um município do Piauí, Brasil. Método Estudo transversal realizado com uma amostra de 384 pessoas idosas hipertensas, selecionadas por amostragem aleatória. Utilizou-se questionário contendo aspectos sociodemográficos, comportamentos de saúde, presença de comorbidades e tratamento para hipertensão. A PA foi aferida por técnica padronizada utilizando aparelhos digitais. Para testar a associação entre as variáveis independentes (sexo, idade, escolaridade, consumo de bebida alcoólica, tabagismo, presença de outras doenças, adesão ao tratamento medicamentoso, entre outras) e a presença de PA não controlada foram realizadas regressões de Poisson com variância robusta, de forma a estimar a razão de prevalência (RP) e intervalos de confiança (IC) de 95%. Resultados A prevalência de PA não controlada foi de 61,7% e 51,8% apresentaram baixa adesão à medicação anti-hipertensiva. A prevalência de PA não controlada foi maior entre os participantes com baixa adesão à medicação (RP=2,41; IC95%: 1,96-2,97) quando comparada àqueles com alta adesão. Associações estatisticamente significativas não se mantiveram para as demais variáveis estudadas. Conclusão Os achados destacam a alta prevalência de PA não controlada entre os idosos e uma associação importante entre PA não controlada e baixa adesão ao tratamento. Intervenções eficientes para melhor controle da hipertensão continuam sendo necessárias, bem como estratégias para o manejo adequado da doença no âmbito da atenção básica, desde ações de prevenção até planos de tratamento apropriados a cada indivíduo.

RESUMO: Objetivo: Analisar o comportamento da prevalência de hipertensão arterial no município de São Paulo e seus fatores associados. Métodos: O presente trabalho utilizou os dados do Inquérito de Saúde no Município de São Paulo (ISA Capital), estudo transversal de base populacional executado no município de São Paulo. Foram utilizados dados de 1.667 e de 3.184 indivíduos em 2003 e 2015, respectivamente, com idade de 20 anos e mais. Fizeram-se análises descritivas das prevalências de hipertensão arterial com respectivos intervalos de 95% de confiança. Análises simples e múltiplas foram realizadas para analisar possíveis associações com as variáveis socioeconômicas, demográficas e de estilo de vida por meio de regressão de Poisson. Resultados: A prevalência de hipertensão arterial passou de 17,2% em 2003 para 23,2% em 2015. Os fatores associados à hipertensão foram: sexo feminino; idade (60 anos e mais); situação conjugal (casados, separados e viúvos); ter religião; baixa escolaridade; ter nascido no estado de São Paulo (exceto capital); estado nutricional (baixo peso, sobrepeso e obesidade); e ex-fumantes. Conclusão: A prevalência de hipertensão autorreferida aumentou significativamente no período estudado em São Paulo. Considerando o impacto dessa doença na sociedade, conhecendo sua atual prevalência e identificando seus principais fatores associados, evidencia-se a necessidade de intensificar atividades que contribuam para a prevenção desse agravo, atenuando os danos aos indivíduos e gastos públicos.

Epidemiology of artherial hypertension in pregnants

OBJECTIVE

To investigate the epidemiological data of hypertension in pregnant women, as well as to identify its possible associated events.

METHODS

Data collection was performed at the high-risk prenatal outpatient clinic and in the maternity ward at a public hospital in the São Paulo city, during the morning and afternoon periods, from October 2015 to July 2016. A questionnaire with 22 questions prepared by the researchers was used. The margin of error was 5% and the confidence level was 95%. For the calculation, the two-proportion equality, Pearson correlation and ANOVA tests were used.

RESULTS

Among the interviewees, 43% had chronic hypertension, 33.3% presented with up to 20 weeks of gestation, 23.7% presented after the 20th week of gestation, 62.3% were between 18 and 35 years of age, 78.1% had a family history of hypertension, and among those aged 36 to 45 years, 11.4% were in the first gestation, and 26.3% in the second gestation. Considering the associated conditions, diabetes prevailed with 50%; obesity with 22.2%, and the most selected foods for consumption among pregnant women, 47.5% had high energy content (processed/ultraprocessed).

CONCLUSION

After an epidemiological analysis of the prevalence of hypertension, pregnant women with chronic hypertension, preexisting hypertension diagnosed during pregnancy, and hypertensive disease of pregnancy were identified. Regarding the possible factors associated with arterial hypertension, higher age, family history of hypertension, preexistence of hypertension, late pregnancies, diabetes, obesity and frequent consumption of processed/ultraprocessed foods were found.

Social inequalities in the prevalence of indicators of active aging in the Brazilian population: National Health Survey, 2013

OBJECTIVE

To analyze social inequalities in the prevalence of indicators of active aging in the Brazilian older adult population.

METHODS

This is a cross-sectional study with a sample of 11,177 older adults who participated in the Brazilian National Health Survey in 2013. We estimated the prevalence of five domains of active aging (social activities, civic engagement, leisure-time physical activity, paid work, and volunteer work) according to gender, ethnicity, schooling, income, and private health insurance. Prevalence ratios and confidence intervals were calculated using Poisson regression.

RESULTS

The percentage of involvement in organized social activities, civic engagement, and physical activity was 25.1, 12.4, and 13.1%, respectively. Regarding work, 20.7% of the sample had a paid job, and 9.7% participated in volunteer work. Women had a higher prevalence of participation in organized social activities and volunteer work; while civic engagement and paid work were more frequent among men. White people were more likely to participate in social activities, volunteer work, and leisure-time physical activity, explained by their schooling. The strata with a higher level of schooling, income, and who had private health insurance showed a greater incidence of participation in all activities studied.

CONCLUSION

The five activities analyzed are challenging for the proposed policy of active aging, as they are marked by considerable social inequality.

Falha no diagnóstico e no tratamento medicamentoso da hipertensão arterial em idosos brasileiros – Estudo FIBRA

Resumo O objetivo deste estudo foi investigar prevalências de falhas no diagnóstico, no uso de anti-hipertensivos e na eficácia do tratamento medicamentoso da hipertensão, e a associação destes parâmetros com variáveis sociodemográficas, de saúde e acesso ao serviço de saúde em idosos não institucionalizados. O estudo foi descritivo, transversal, com 3478 idosos, analisados separadamente em regiões Norte/Nordeste e Sul/Sudeste. Utilizou-se a regressão múltipla de Poisson para estimar razões de prevalência brutas e ajustadas pelo tipo de serviço de saúde utilizado. Do total, 29,6% dos idosos apresentaram falhas no diagnóstico, 4,6% no uso de anti-hipertensivos e 65,3% na eficácia medicamentosa. A falha no diagnóstico associou-se ao sexo masculino, menos morbidades, ter um companheiro, raça/cor branca, ter acesso ao convênio ou serviço privado de saúde, possuir renda pessoal inferior/média e ainda trabalhar. A falha no uso de anti-hipertensivos esteve associada à renda pessoal inferior/média e trabalhar. As falhas no manejo da hipertensão são prevalentes em idosos não institucionalizados. Há necessidade de ações que minimizem os impactos negativos destas insuficiências em saúde, em um país com diferenças sociais, econômicas e étnicas.

Prevalence of Systemic Arterial Hypertension Diagnosed, Undiagnosed, and Uncontrolled in Elderly Population: SABE Study

Systemic arterial hypertension is the most prevalent chronic noncommunicable disease among older people. This study aimed to estimate the prevalence of hypertension in the elderly and to analyze factors associated with diagnosed, undiagnosed, and uncontrolled hypertension. This is a cross-sectional study of data from the SABE study-Health, Well-Being, and Aging Survey-a multiple-cohort study, obtained in 2010, composed of a probabilistic sample representative of the population of the São Paulo city aged ≥60 years. Hypertension was self-reported or defined by increased blood pressure. Multinomial regression assessed factors associated with diagnosis and lack of diagnosis of hypertension (reference: no hypertension), and logistic regression assessed factors associated with uncontrolled hypertension (reference: controlled). The prevalence of hypertension was 79.5%, and in 51% of individuals with the condition, hypertension was uncontrolled. Undiagnosed hypertension was associated with nonwhite skin color (OR: 1.89, CI: 1.11-3.19), being uninsured (OR: 1.77, CI: 1.04-3.03), overweight (OR: 2.38, CI: 1.09-5.19), higher education (OR: 0.46, CI: 0.22-1.94), and ≥1 chronic disease (OR: 0.28; CI: 0.13-0.58). Diagnosed hypertension was associated with age between 70 and 79 years (OR: 2.02, CI: 1.34-3.05), age ≥80 (OR: 2.73, CI: 1.72-4.31), nonwhite skin color (OR: 1.48, CI: 1.01-2.18), being uninsured (OR: 1.70, CI: 1.18-2.47), at least one medical consultation in the last year (OR: 1.86, CI: 1.06-3.25), obesity (OR: 2.50, CI: 1.61-3.88), and ≥1 chronic disease (OR: 2.81, CI: 1.94-4.08). Among those with hypertension, being uncontrolled was associated with widowhood (OR: 1.73, CI: 1.23-2.43), being uninsured (OR: 1.38, CI: 1.02-1.87), and female gender (OR: 0.61, CI: 0.43-0.87). The prevalence of hypertension was high in this population, and its diagnosis and control were associated with socioeconomic, demographic, and healthcare access factors.

Prevalence and factors associated with underweight among Brazilian older adults

The aim of this study was to estimate the prevalence of underweight among older adults according to socio-demographic characteristics in different regions of Brazil as well as determine associated contextual and individual factors. Cross-sectional population-based study with older adults (≥ 65 years) interviewed by telephone survey in 2014. The body mass index was calculated based on weight and height. Associations were determined using Pearson's chi-square test, considering a 5% significance level. Adjusted prevalence ratios were estimated using multilevel Poisson regression. Mean age was 73.3 years and the prevalence of underweight was 15.6% (95%CI: 14.1-17.1%). Higher prevalence rates of underweight were found among women, individuals aged ≥ 80 years, smokers and those who reported the regular consumption of beans. The prevalence rate of underweight was lower among those who reported abusive alcohol intake and those with a medical diagnosis of hypertension. The northern region of the country had the highest prevalence of underweight after adjusting for associated individual factors. The findings demonstrate the subgroups with higher prevalence rates of underweight that demand greater attention from the health services in terms of recovering of an adequate nutritional status.

Factors associated with blood pressure disorders in Afro-descendant children and adolescents

BACKGROUND

Hypertension (AH) is an emerging disease that has rapidly increased in the last decades throughout the world. The increase in blood pressure (BP) is observed with growth and development and, although the manifestation of the disease is rare in childhood and adolescence, its occurrence is increasing and the causes are likely to be from different combinations of factors. Afrodescendants have been consistently observed in many populations, including Brazil, which has the largest population of Afrodescendants outside Africa; nevertheless, data is scarce on the disease in children and adolescents. In this study, we investigated BP disorders in children and adolescents of "Quilombola" populations of the state of Tocantins, northern Brazil, and determined the disease occurrence with some factors, namely food consumption, body composition, anthropometric measures, and biochemical data.

METHODS

We carried out a cross-sectional study with 67 children aged 10-17 years, comparing the variables studied between the normotensive and non-normotensive groups, using the Chi-square test for qualitative variables and the appropriate tests, according to data adherence to the Gaussian distribution for the quantitative variables. High blood pressure was defined as mean systolic or diastolic blood pressure ≥ 90 percentile for age, height, gender.

RESULTS

The rate of adolescents with BP disorders was 19.4% (prehypertension 14.9% and hypertension 4.5%). There were no significant differences between the sexes for high blood pressure. In the Poisson regression analysis, the high fat percentage was associated with elevated blood pressure (p = 0.021) for adolescents. Similar associations were observed for non-HDL-c (p < 0.001) and low calcium intake (p = 0.015).

CONCLUSION

Most children and adolescents in "Quilombola" communities had normal blood pressure. However, higher levels of dyslipidemia and low calcium intake are factors associated with prehypertension in the population studied with high BP.

Reclassification of the Framingham risk score and its agreement with other three calculations

Objective: To investigate the concordance between the modified Framingham score using the ankle-brachial index and the high-sensitivity C-reactive protein with the other scores. Materials and method: Cross-sectional study nested with a cohort, with elderly population, from January to March, 2018. The population characterization was presented as mean, median, absolute and relative frequencies according to degree of normality. The Kappa concordance of the modified Framingham score was calculated with the Framingham score itself, with the Systematic Coronary Risk Evaluation (Score) and with the Prospective Cardiovascular Munster (Procam). Results: The modified Framingham score shows moderate Kappa concordance with the Framingham score and the Score (p < 0.001), but weak with Procam. The ultra-sensitive C-reactive protein presented more reclassification of individuals among risk strata than the ankle-brachial index. Conclusions: The Framingham score modified with the Framingham score itself, and then with the Score obtained a higher proportion of concordant cases in the high-risk stratum. High-sensitivity C-reactive protein and the ankle-brachial index modify cardiovascular risk as emerging factors to provide an accurate risk stratification and to infer better management of the therapy. Thus, the Framingham score with its reclassification is the best screening tool for cardiovascular risk.

Prevalence of arterial hypertension in Brazilian adults and its associated factors and activity limitations: a cross-sectional study

BACKGROUND

Hypertension is a serious global public health problem that affects a large part of the Brazilian adult population and can cause limitations and losses of quality of life.

OBJECTIVE

The objective of this study was to analyze the association of hypertension and its correlated limitations, with sociodemographic and epidemiological factors.

DESIGN AND SETTING

Cross-sectional study analyzing information on 44,271 adults (30 years or older) from the Brazilian National Health Survey of 2013.

METHODS

The prevalence of hypertension and the degree of limitation of the patients' activities associated with hypertension, according to sociodemographic characteristics, anthropometric measurements and lifestyles, were calculated for both sexes. To analyze the strength of association, bivariate and multivariate Poisson regression were used.

RESULTS

Hypertension was the most prevalent risk factor among Brazilian adults aged 30 years or older (40.7%). It was strongly associated with the aging process (prevalence ratio, PR 3.51), obesity (PR 1.73), heart disease (PR 1.67) and stroke (PR 1.86). Furthermore, limitations associated with hypertension were more prevalent among those with comorbidities from noncommunicable diseases relating to hypertension complications (stroke PR 1.47; heart disease PR 1.69) and with incomplete elementary education (PR 1.19).

CONCLUSIONS

This study showed sociodemographic inequality in the prevalence of hypertension, especially in the population with some degree of limitation associated with hypertension. It showed that improvements in access to primary care services for controlling hypertension at its initial stages are essential in order to avoid comorbidities of greater severity and limitations and losses of quality of life, especially among socially disadvantaged people.

Association between follow-up in health services and antihypertensive medication adherence

OBJECTIVE

To analyze the association between the characteristics of follow-up in health services and adherence to antihypertensive medication in patients with cardiovascular disease.

METHOD

Analytical study carried out with 270 patients suffering from hypertension and hospitalized due to cardiovascular complications. Data collection occurred between November 2015 and April 2016, involving sociodemographic variables, presence of self-reported diabetes, accessibility and use of health services, blood pressure levels and medication adherence (analyzed through the Morisky-Green Test).

RESULTS

The rate of adherence to antihypertensive therapy was 63.0%. Enrollment in the Hiperdia program had no statistical significance to medication adherence. People who attended at least between 4 and 6 nursing consultations throughout the data collection period (p = 0.02) had better adherence.

CONCLUSION

The study's findings provide support for the reorientation of health services and their public policies towards improving adherence to antihypertensive therapeutics.

Prevalência simultânea de hipertensão e diabetes em idosos brasileiros: desigualdades individuais e contextuais

Resumo A prevalência da simultaneidade de doenças específicas nos idosos ainda é pouco descrita na literatura. O objetivo do estudo foi estimar a prevalência simultânea de hipertensão arterial e diabetes mellitus em idosos brasileiros, e os fatores contextuais e individuais a ela associados. Estudo transversal de base populacional com idosos (≥ 60 anos) entrevistados pelo Vigitel em 2012 (n = 10.991). As análises foram realizadas por meio de regressão de Poisson multinível no Stata 12. A média de idade dos idosos foi de 69,4 anos e a prevalência simultânea das doenças foi de 16,2% com variação nas capitais brasileiras. Em São Paulo e Curitiba as prevalências foram mais elevadas do que em Boa Vista e Manaus. Maiores prevalências foram observadas nas capitais das regiões Sul/Sudeste/Centro-Oeste, nos idosos de cor preta e parda, naqueles com escolaridade ≤ 8 anos de estudo, nos não fumantes e ex-fumantes, e com excesso de peso. Verificou-se o efeito da região geográfica na prevalência simultânea pela elevação de 23,5% na magnitude da razão de prevalencia, após ajuste para todas as variáveis individuais. Por meio do estudo, foi possível dimensionar o efeito do contexto onde estão inseridos os idosos (região de residência) sobre a prevalência das principais doenças que acometem e relacionam-se à mortalidade na população idosa na atualidade.

[Prevalence of arterial hypertension, diabetes mellitus, and adherence to behavioral measures in the city of São Paulo, Brazil, 2003-2015]

The objective was to compare the estimates for prevalence of diabetes, hypertension, and behavioral measures to control these diseases. Data were analyzed for the adult population from Health Surveys in the city of São Paulo, Brazil, in 2003, 2008, and 2015. Prevalence rates and 95% confidence intervals (95%CI) were calculated for the following: hypertension, diabetes, and practices to control these diseases (diet, physical activity, oral medication, insulin, nothing). Estimates were compared by age and sex-adjusted Poisson regression and analyzed according to the 20-59-years and 60-and-older age brackets. The data were presented comparing 2008 to 2003 and 2015 to 2003. Among persons 20 to 59 years of age, there was an increase in the prevalence rates for: hypertension in 2003-2015 (PR = 1.27; 95%CI: 1.03-1.60) and diet for both periods (2003-2008, PR = 2.04; 95%CI: 1.42-2.91; and 2003-2015, PR = 1.51; 95%CI: 1.05-2.15). Among persons 60 years and older: diabetes (PR = 1.29; 95%CI: 1.08-1.56) and oral medication to control diabetes (PR = 1.38; 95%CI: 1.17-1.63), both in 2003-2015; hypertension in 2003-2015 (PR = 1.19; 95%CI:1.05-1.39); and diet and oral medication to control hypertension in 2003-2008 (PR = 1.20; 95%CI: 0.95-1.51 and PR = 1.02; 95%CI: 0.95-1.09, respectively). The results are important for surveillance and monitoring of the target indicators and provide backing for planning health care activities in the city of São Paulo. Linking and aligning effective and integrated interventions is indispensable for reducing and controlling these chronic noncommunicable diseases.

Cytotoxic and genotoxic effects of antihypertensives distributed in Brazil by social programs: Are they safe?

Hypertension, a chronic non-transmissible multifactorial condition, it is highly frequent in Brazil, affecting about 32.5% of the population over 25 years of age. It is characterized by the sustained increase in systolic and diastolic blood pressure levels above 140 mmHg and 90 mmHg, respectively. It is the major aggravating factor in cardiovascular complications and the appearance of other comorbidities. Aiming to promote greater adherence to treatment and improve the population's access to basic medicament, in 2004 the Federal Government created the Programa Farmácia Popular do Brasil (PFPB); partnership with private institutions that provides the population with medicament to control hypertension, free of charge or subsidized at up to 90% of the value. The PFPB distributes the anti-hypertensives atenolol, captopril, enalapril, hydrochlorothiazide, losartan and propranolol. In this way, this work aims to evaluate the genotoxic potential of antihypertensives in human lymphocytes and macrophages, since they are widely used drugs and with few studies about their genotoxicological safety. The tests were developed from cell cultures treated with five different antihypertensive concentrations, all based on plasma peaks, evaluating cell viability, DNA damage index and DNA double strand breakdown. The results show that, as the concentration of captopril and enalapril maleate increased, cell viability decreased. In addition, a DNA damage was observed with the use Captopril and Enalapril in the higher concentrations. Hydrochlorothiazide also caused DNA damage in the five doses tested. Regarding the breaking of double strands of DNA, all the compounds showed increased ruptures. This decrease in dsDNA is dose dependent for all compounds tested. The set of results shows that the use although frequent still requires care and greater knowledge. In general, the antihypertensive drugs that proved to be safer in relation to the genetic damage tested were Losartan and Propranolol.

Cardiovascular risk stratification among hypertensive patients: the influence of risk factors

OBJECTIVE

to assess the cardiovascular risk in hypertensive patients and the influence of risk factors on the stratification scores.

METHODS

this is a cross-sectional study with hypertensive patients undergoing outpatient follow-up from November 2014 to February 2015. The Global Risk Score was used to assess cardiovascular risk. To assess the influence of the risk factors with the stratification of the cardiovascular risk score, the main components analysis was used.

RESULTS

57 patients participated in the study, and the majority (93.1%) was considered to be at high cardiovascular risk; the analysis of the main components identified five components that explain 85.2% of the total variation.

CONCLUSION

the cardiovascular risk assessment demonstrated the importance of the identification of risk factors and, consequently, the need to implement actions aimed at controlling these factors, which constitutes a challenge in the adequate management of arterial hypertension.

Ageing with Chagas disease: an overview of an urban Brazilian cohort in Rio de Janeiro

BACKGROUND

Chagas disease control programmes have decreased the prevalence of Chagas disease in Latin America. Together with migration to urban areas and increase in life expectancy, a new scenario for Chagas disease has emerged in Brazil with most patients currently elderly individuals living in urban areas. However, acute Chagas disease cases still occur due to vector transmission by sylvatic vectors and oral transmission by contaminated food. Therefore, we characterized the clinical and epidemiological profile of the patients followed at Evandro Chagas National Institute of Infectious Diseases in Rio de Janeiro, Brazil. We aimed to identify the clinical forms, associated co-morbidities, and geographical areas where younger patients originate from. This will aid in the identification of potential challenges to be currently faced.

RESULTS

This is a cross-sectional study. Adult patients with chronic Chagas disease were recruited between March 2013 and April 2016. Clinical and epidemiological data were obtained from electronic medical records and interviews. The clinical form of the Chagas disease presented by the patients was determined following the Brazilian Consensus on Chagas disease. Six hundred and nineteen patients (mean age 60 ± 12 years; 56.9% women) were included in this study. Patients' clinical forms were classified as follows: indeterminate 29.1%; cardiac 55.4%; digestive 5.5%; and mixed 10.0%. Patients aged over 65 years comprised 38% of the population. Hypertension was present in 347 (56%) patients, dyslipidemia in 261 patients (42%) and diabetes mellitus in 185 patients (30%). There were no differences regarding gender, race, comorbidities frequency or place of origin across Chagas disease clinical forms. Most of the elderly population originated from Bahia, Minas Gerais and Pernambuco states, while most of the younger patients were born in Ceará, Paraíba and Rio de Janeiro states.

CONCLUSIONS

We described a great proportion of elderly patients in the composition of an urban Brazilian Chagas disease patient cohort with a high prevalence of comorbidities. We also identified a change in the pattern of the place of origin among younger patients.

Accuracy of self-reported hypertension in Brazilian adolescents: Analysis of the Study of Cardiovascular Risk in Adolescents

Given the high prevalence of hypertension in adolescents, it is important to investigate alternatives for estimating the magnitude of the disease. Our objective was to investigate the accuracy of self-reported hypertension. The study assessed participants of the Study of Cardiovascular Risk in Adolescents (ERICA). The following were calculated: sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The associations between inaccurate self-reporting and socioeconomic factors were investigated. The accuracy of self-reported hypertension had a sensitivity of 7.5% (95% CI, 6.9-8.2), a specificity of 96.6% (95% CI, 96.5-96.7), a PPV of 18.9% (95% CI, 17.4-20.5), and a NPV of 90.8% (95% CI, 90.6-91.0). The prevalence of inaccurate self-reported hypertension was smaller among girls (PR 0.68; 95% CI, 0.55-0.83) and younger boys (PR 0.68; 95% CI, 0.54-0.86) who were attending private schools. The use of self-reported hypertension was not a good strategy for investigating the hypertension in adolescents.

[Arterial prehypertension in slave-descendant communities in southeast Bahia State, Brazil]

Arterial prehypertension is a precursor of arterial hypertension and a risk factor for cardiovascular diseases. Vulnerable populations are more prone to this condition due to difficulties in access to health services. A previous study in quilombola communities (descendants of African slaves) reported a high prevalence of arterial hypertension. The current study aimed to estimate the prevalence of arterial prehypertension in quilombolas and to assess associated factors. This was a cross-sectional population-based study in individuals 18 years and older. Prehypertension was defined as arterial systolic pressure ≥ 121mmHg and < 140mmHg and/or diastolic ≥ 81mmHg and < 90mmHg. Multivariate Poisson regression with robust variance was used. Population-attributable fractions (PAF) were also calculated for the modifiable associated factors. Prevalence of prehypertension was 55% (95%CI: 50.2-59.7). Male gender (PR = 1.54), 1 to 4 complete years of schooling (PR = 1.44), and BMI classified as overweight (PR = 1.39) and obesity (PR = 1.87) showed positive association with prehypertension. Higher attributable fractions were observed in individuals with 1 to 4 years of schooling (13.7%) and those classified as overweight (9.35%) and obese (4.6%). Prevalence of prehypertension in quilombola communities was high, and its identification may allow screening and awareness-raising in a group with increased risk of cardiovascular disease and progression to full-blown hypertension. The study highlights the need for broad access to health services and specific measures for orientation, prevention, and health promotion in this population.
