The Association Between Life Events and Incidence of Hypertension Among Government Employees in China: A Prospective Cohort Study. Front Psychol 2022; 13:822610. [PMID: 35707654 PMCID: PMC9190203 DOI: 10.3389/fpsyg.2022.822610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Accepted: 04/25/2022] [Indexed: 11/13/2022] Open
Abstract
Background Hypertension (HTN) is a global public health concern. However, the association between life events (LEs) and HTN is complex. Thus, we conducted a prospective cohort study to explore this complex association. Methods A total of 8,077 government employees without HTN were recruited through cluster sampling between 2018 and 2019 in Hunan Province, China. At baseline, information regarding sociodemographic characteristics, LEs, and behavioral factors was collected. After the 1-year follow-up, the participants were revisited to obtain the HTN diagnosis. Crude and adjusted Poisson regression models were constructed to calculate the incidence rate ratios (IRRs) and 95% confidence intervals (CIs). Cubic regression spline models were used to visualize the trends between LEs and HTN IRRs. Interactive and subgroup analyses were also performed. Results The 1-year HTN incidence rate among government employees in Hunan province was 4.30% (95% CI: 3.86-4.74%). LEs were associated with a higher HTN risk (IRR, 1.02; 95% CI, 1.00-1.04). When calculating positive and negative LEs scores separately, only the latter was a risk factor for HTN incidence (IRR, 1.04; 95% CI, 1.03-1.06); conversely, positive LEs reduced the risk (IRR, 0.90; 95% CI, 0.85-0.96). Compared with patients in the lowest quartile of LEs score, those in quartiles two (IRR, 1.28; 95% CI, 0.96-1.71), three (IRR, 1.43; 95% CI, 1.04-1.96), and four (IRR, 1.73; 95% CI, 1.26-2.37) were at progressively higher risk. In restricted spline curves, a non-linear association was noted between LEs and HTN risk. Regarding the subcategories of LEs, work-related LEs, personal LEs, and all subcategories of negative LEs were associated with an increased risk of HTN. However, among positive LEs, only the family-related cases were associated with a lower risk of HTN. Conclusion LEs had a non-linear association with an increased risk of HTN. Negative LEs were risk factors for HTN incidence, whereas positive LEs reduced the risk of HTN. Thus, the importance of LEs should be highlighted in the development of HTN prevention strategies and initiatives.

Behavioral and Sociodemographic Determinants of Hypertension and Its Burden among Bank Employees in Metropolitan Cities of Amhara Regional State, Ethiopia. Int J Hypertens 2021; 2021:6616473. [PMID: 34327014 PMCID: PMC8302382 DOI: 10.1155/2021/6616473] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 07/03/2021] [Accepted: 07/08/2021] [Indexed: 12/15/2022] Open
Abstract
Background Hypertension is the leading cause of cardiovascular disease and premature death worldwide. Bank workers are at higher risk of hypertension because of their work sedentary characteristics. However, little is known about the prevalence and determinants of hypertension among this group of population. Therefore, this study aimed to assess the prevalence and associated factors of hypertension among bank employees in metropolitan cities in Amhara Regional State of Ethiopia. Method An institution-based cross-sectional study was conducted among 368 bank employees. A simple random sampling technique was used to select participants. A pretested self-administered questionnaire and biophysical measurements were employed to collect the data. Descriptive statistics and logistic regression analyses were done to summarize the data and identify factors associated with hypertension, respectively. Result The overall prevalence of hypertension among bank employees was 52.4% (95% CI: 47.2, 57.7). Increased age (AOR = 1.1, 95% CI: 1.03, 1.11), male sex (AOR = 2.5, 95% CI: 1.2, 5.1), overweight (AOR = 2.7, 95% CI: 1.5, 5.2), obesity (AOR = 5.6, 95% CI: 2.0, 11.3), moderate/high physical activity (AOR = 0.36, 95% CI: 0.2, 0.62), daily fruit intake (AOR = 0.1, 95% CI: 0.04, 0.3), stressful life event experience (AOR = 1.8, 95% CI: 1.01, 3.4), family history of hypertension (AOR = 2.8, 95% CI: 1.5, 5.4), and poor knowledge of CVDs (AOR = 2.4, 95% CI: 1.2, 4.8) were significantly associated with hypertension. Conclusion The prevalence of hypertension among bank workers was very high. Increased age, male sex, overweight and obesity, daily fruit intake, moderate/high physical activity, the experience of stressful events, familial history of hypertension, and poor CVDs knowledge were associated with hypertension. Thus, raising awareness about cardiovascular disorders and behavior change interventions that enhance bank workers' engagement in physical exercise, screening behavior, and a healthy diet is urgently required for this group of population.

Abstract
Background Domestic abuse (DA) against women is a global public health problem. Although the possible health burden could be substantial, the associations between DA and subsequent cardiometabolic disease (cardiovascular disease, hypertension, and type 2 diabetes mellitus) and all-cause mortality are poorly understood. Methods and Results This retrospective cohort study consisted of UK-based primary care patients between January 1, 1995, to December 1, 2017. Overall, 18 547 women exposed to DA were matched to 72 231 unexposed women by age and lifestyle factors. The main outcomes, presented as adjusted incidence rate ratios (IRRs), were the risk of developing cardiovascular disease, hypertension, type 2 diabetes mellitus, and all-cause mortality. In total, 181 exposed women experienced a cardiovascular disease event compared with 644 of the unexposed control group, relating to an increased adjusted IRR of 1.31 (95% CI, 1.11-1.55; P=0.001). There was also an increased risk of subsequent type 2 diabetes mellitus (adjusted IRR: 1.51; 95% CI, 1.30-1.76; P<0.001) and all-cause mortality (adjusted IRR: 1.44; 95% CI, 1.24-1.67; P<0.001) following exposure to DA. This observation was not seen with hypertension (adjusted IRR: 0.99; 95% CI, 0.88-1.12; P=0.873). Conclusions There is an increased risk of subsequent cardiovascular disease, type 2 diabetes mellitus, and all-cause mortality in female survivors of DA. However, there is no association with the development of hypertension in this group, in keeping with previous literature. Considering the high prevalence of DA, clinicians should be made aware of the disproportionally increased risk and thus are encouraged to manage modifiable risk factors actively in this group.

Abstract
Despite progress made to prevent and control hypertension, its prevalence has
persisted in many countries. This study examined the associations between
psychosocial factors and hypertension among Ghanaian non-migrants and migrants.
Data were drawn from the Research on Obesity and Diabetes among African Migrants
(RODAM) project. Findings show that among migrant women, those who experienced
periods of stress at home/work had higher odds of hypertension. Among
non-migrants, women with depression symptoms were more likely to be
hypertensive. Furthermore, there was a positive association between negative
life events and hypertension among non-migrant men. The findings highlight the
importance of psychosocial factors in addressing hypertension prevalence in
Ghanaian populations.

Abstract
Stress is considered a risk factor associated with the development of various civilization diseases including cardiovascular diseases, malignant tumors and mental disorders. Research investigating mechanisms involved in stress-induced hypertension have attracted much attention of physicians and researchers, however, there are still ambiguous results concerning a causal relationship between stress and long-term elevation of blood pressure (BP). Several studies have observed that mechanisms involved in the development of stress-induced hypertension include increased activity of sympathetic nervous system (SNS), glucocorticoid (GC) overload and altered endothelial function including decreased nitric oxide (NO) bioavailability. Nitric oxide is well known neurotransmitter, neuromodulator and vasodilator involved in regulation of neuroendocrine mechanisms and cardiovascular responses to stressors. Thus NO plays a crucial role in the regulation of the stress systems and thereby in the BP regulation in stress. Elevated NO synthesis, especially in the initial phase of stress, may be considered a stress-limiting mechanism, facilitating the recovery from stress to the resting levels via attenuation of both GC release and SNS activity as well as by increased NO-dependent vasorelaxation. On the other hand, reduced levels of NO were observed in the later phases of stress and in subjects with genetic predisposition to hypertension, irrespectively, in which reduced NO bioavailability may account for disruption of NO-mediated BP regulatory mechanisms and accentuated SNS and GC effects. This review summarizes current knowledge on the role of stress in development of hypertension with a special focus on the interactions among NO and other biological systems affecting blood pressure and vascular function.

Abstract
We aimed to obtain overall and regional estimates of hypertension prevalence, and to examine the pattern of this disease condition across different socio-demographic characteristics in low-and middle-income countries. We searched electronic databases from inception to August 2015. We included population-based studies that reported hypertension prevalence using the current definition of blood pressure ≥140/90 mm Hg or self-reported use of antihypertensive medication. We used random-effects meta-analyses to pool prevalence estimates of hypertension, overall, by World Bank region and country income group. Meta-regression analyses were performed to explore sources of heterogeneity across the included studies. A total of 242 studies, comprising data on 1,494,609 adults from 45 countries, met our inclusion criteria. The overall prevalence of hypertension was 32.3% (95% confidence interval [CI] 29.4-35.3), with the Latin America and Caribbean region reporting the highest estimates (39.1%, 95% CI 33.1-45.2). Pooled prevalence estimate was also highest across upper middle income countries (37.8%, 95% CI 35.0-40.6) and lowest across low-income countries (23.1%, 95% CI 20.1-26.2). Prevalence estimates were significantly higher in the elderly (≥65 years) compared with younger adults (<65 years) overall and across the geographical regions; however, there was no significant sex-difference in hypertension prevalence (31.9% vs 30.8%, P = 0.6). Persons without formal education (49.0% vs 24.9%, P < 0.00001), overweight/obese (46.4% vs 26.3%, P < 0.00001), and urban settlers (32.7% vs 25.2%, P = 0.0005) were also more likely to be hypertensive, compared with those who were educated, normal weight, and rural settlers respectively. This study provides contemporary and up-to-date estimates that reflect the significant burden of hypertension in low- and middle-income countries, as well as evidence that hypertension remains a major public health issue across the various socio-demographic subgroups. On average, about 1 in 3 adults in the developing world is hypertensive. The findings of this study will be useful for the design of hypertension screening and treatment programmes in low- and middle-income countries.

Abstract
CONTEXT Violence, experienced in either childhood or adulthood, has been associated with physical health outcomes, including cardiovascular disease. However, the consistency of the existing literature has not been evaluated. EVIDENCE ACQUISITION In 2013, the authors conducted a PubMed and Web of Science review of peer-reviewed articles published prior to August 2013 on the relation between violence exposure, experienced in either childhood or adulthood, and cardiovascular outcomes. To meet inclusion criteria, articles had to present estimates for the relation between violence exposure and cardiovascular outcomes (e.g., hypertension, blood pressure, stroke, coronary disease, or myocardial infarction) adjusted for demographic factors. Articles focusing on violence from television, video games, natural disasters, terrorism, or war were excluded. EVIDENCE SYNTHESIS The initial search yielded 2,273 articles; after removing duplicates and applying inclusion and exclusion criteria, 30 articles were selected for review. A consistent positive relation was noted on the association between violence experienced during childhood and cardiovascular outcomes in adulthood (i.e., hypertension, coronary heart disease, and myocardial infarction). Associations across genders with varying types of violence exposure were also noted. By contrast, findings were mixed on the relation between adult violence exposure and cardiovascular outcome. CONCLUSIONS Despite varying definitions of violence exposure and cardiovascular endpoints, a consistent relation exists between childhood violence exposure, largely assessed retrospectively, and cardiovascular endpoints. Findings are mixed for the adult violence-cardiovascular health relation. The cross-sectional nature of most adult studies and the reliance of self-reported outcomes can potentially be attributed to the lack of findings among adult violence exposure studies.

Abstract
The whole range of blood pressure (BP) has important implications. Yet, published studies focus primarily on hypertension and hypotension, the two extremes of BP continuum. This study aims at exploring quantile-specific associations of BP with common factors. The study used cross-sectional survey, collected information about gender, age, education, body mass index (BMI), alcohol intake, diet risk behavior, life event index, physical activity, fasting capillary glucose (FCG), and systolic/diastolic blood pressure (SBP/DBP) and pulse pressure (PP) from farmers living in 18 villages from rural Anhui, China, and performed descriptive and multivariate and quantile regression (QR) analysis of associations of SBP, DBP, or PP with the 9 factors surveyed. A total of 4040 (86.3%) eligible farmers completed the survey. Average hypertension prevalence rate and SBP, DBP, and PP values estimated 43.20 ± 0.50% and 141.37 ± 21.98, 87.76 ± 12.23, and 53.63 ± 15.72 mm Hg, respectively. Multivariate regression analysis revealed that all the 9 factors were significantly (P < 0.05) associated with one or more of SBP, DBP, and PP. QR coefficients of SBP, DBP, or PP with different factors demonstrated divergent patterns and age, BMI, FCG, and life event index showed substantial trends along the quantile axis. Hypertension prevalence rate was high among the farmers. QR modeling provided more detailed view on associations of SBP, DBP, or PP with different factors and uncovered apparent quantile-related patterns for part of the factors. Both the population group studied and the trends in QR coefficients identified merit specific attention.

Abstract
Background Hypertension is highly prevalent among recent sub-Saharan African (SSA) migrants in western countries and some tend to associate their hypertension to psychosocial stress. However data on the relationship between hypertension and psychosocial stress among SSA migrants are rare. We assessed the relationship between psychosocial stress and hypertension among the largest SSA migrant population (Ghanaians) in Amsterdam, the Netherlands. Methods Data were obtained from structured interviews along with medical examination among 212 participants from a cross-sectional study: the GHAIA study in 2010 in Amsterdam. Blood pressure was measured with a validated Oscillometric automated digital blood pressure device. Psychosocial stress was assessed by questionnaires on perceived discrimination, depressive symptoms and financial problems. Binary logistic regression was used to study associations between psychosocial stress and hypertension. Results The overall prevalence of hypertension was 54.7%. About two thirds of the study population experienced a moderate (31%) or high (36%) level of discrimination. 20.0% of the participants had mild depressive symptoms, whilst 9% had moderate depressive symptoms. The prevalence of financial stress was 34.8%. The psychosocial stresses we assessed were not significantly associated with hypertension: adjusted odds ratios comparing those with low levels and those with high levels were 0.99 (95% CI, 0.47–2.08) for perceived discrimination, 0.81 (95% CI, 0.26–2.49) for depressive symptoms and 0.71 (95% CI, 0.37–1.36) for financial stress, respectively. Conclusion We did not find evidence for the association between psychosocial stress and hypertension among recent SSA migrants. More efforts are needed to unravel other potential factors that may underlie the high prevalence of hypertension among these populations.

Endothelial dysfunction in experimental models of arterial hypertension: cause or consequence? BIOMED RESEARCH INTERNATIONAL 2014.

Abstract
Hypertension is a risk factor for other cardiovascular diseases and endothelial dysfunction was found in humans as well as in various commonly employed animal experimental models of arterial hypertension. Data from the literature indicate that, in general, endothelial dysfunction would not be the cause of experimental hypertension and may rather be secondary, that is, resulting from high blood pressure (BP). The initial mechanism of endothelial dysfunction itself may be associated with a lack of endothelium-derived relaxing factors (mainly nitric oxide) and/or accentuation of various endothelium-derived constricting factors. The involvement and role of endothelium-derived factors in the development of endothelial dysfunction in individual experimental models of hypertension may vary, depending on the triggering stimulus, strain, age, and vascular bed investigated. This brief review was focused on the participation of endothelial dysfunction, individual endothelium-derived factors, and their mechanisms of action in the development of high BP in the most frequently used rodent experimental models of arterial hypertension, including nitric oxide deficient models, spontaneous (pre)hypertension, stress-induced hypertension, and selected pharmacological and diet-induced models.

The involvement and role of endothelium-derived factors in the development of endothelial dysfunction in individual experimental models of hypertension may vary, depending on the triggering stimulus, strain, age, and vascular bed investigated. This brief review was focused on the participation of endothelial dysfunction, individual endothelium-derived factors, and their mechanisms of action in the development of high BP in the most frequently used rodent experimental models of arterial hypertension, including nitric oxide deficient models, spontaneous (pre)hypertension, stress-induced hypertension, and selected pharmacological and diet-induced models.

Genotype-related effect of crowding stress on blood pressure and vascular function in young female rats. BIOMED RESEARCH INTERNATIONAL 2014; 2014:413629.

Abstract
This study investigated the influence of chronic crowding stress on nitric oxide (NO) production, vascular function and oxidative status in young Wistar-Kyoto (WKY), borderline hypertensive (BHR) and spontaneously hypertensive (SHR) female rats. Five-week old rats were exposed to crowding for two weeks. Crowding elevated plasma corticosterone (P<0.05) and accelerated BP (P<0.01 versus basal) only in BHR. NO production and superoxide concentration were significantly higher in the aortas of control BHR and SHR versus WKY. Total acetylcholine (ACh)-induced relaxation in the femoral artery was reduced in control SHR versus WKY and BHR, and stress did not affect it significantly in any genotype. The attenuation of ACh-induced relaxation in SHR versus WKY was associated with reduction of its NO-independent component. Crowding elevated NO production in all strains investigated but superoxide concentration was increased only in WKY, which resulted in reduced NO-dependent relaxation in WKY. In crowded BHR and SHR, superoxide concentration was either unchanged or reduced, respectively, but NO-dependent relaxation was unchanged in both BHR and SHR versus their respective control group. This study points to genotype-related differences in stress vulnerability in young female rats. The most pronounced negative influence of stress was observed in BHR despite preserved endothelial function.

Abstract
BACKGROUND Mental health problems in those with physical ailments are often overlooked, especially in the former Soviet Union (fSU) where this comorbidity has received little attention. Our study examines the comorbidity of psychological distress and hypertension in the fSU. METHODS Nationally representative household survey data from Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia and Ukraine in 2001 and 2010 were analysed to compare the levels of psychological distress in people with and without self-reported hypertension. Multivariate regression analysed determinants of psychological distress in hypertensive respondents, and prevalence rate ratios were calculated to compare the change in distress between the two groups. RESULTS There were significantly higher levels of psychological distress among hypertensive respondents (9.9%) than in the general population (4.9%), and a significant association between the two conditions [odds ratio (OR) = 2.27 (1.91; 2.70)]. Characteristics associated with distress among hypertensive respondents included residing in Armenia or Kyrgyzstan, being female, over age 50, with a poor economic situation, lower education, poor emotional support and limited access to medical drugs. Levels of distress declined between 2001 and 2010, but at a lesser rate in hypertensive respondents [rate ratio (RR) = 0.85 (0.75; 0.95)] than non-hypertensive respondents [RR = 0.65 (0.56; 0.75)]. CONCLUSIONS There is a significant association between psychological distress and hypertension in the region.

Abstract
Although lay beliefs commonly relate high blood pressure (BP) to psychological stress exposure, research findings are conflicting. This study examined the association between current perceived stress and high BP, and explored the potential impact of occupational status on this association. Resting BP was measured in 122 816 adults (84 994 men), aged ≥30 years (mean age±standard deviation: 46.8±9.9 years), without history of cardiovascular and renal disease and not on either psychotropic or antihypertensive drugs. High BP was defined as systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg. Perceived stress in the past month was measured with the 4-item perceived stress scale. A total of 33 154 participants (27.0%) had high BP (151±14/90±9 mm Hg). After adjustment for all variables except occupational status, perceived stress was associated with high BP (odds ratio [OR] for a 5-point increase: 1.06; 95% confidence interval [CI]: 1.03-1.09). This association was no longer significant after additional adjustment for occupational status (OR: 1.01; 95% CI: 0.99-1.04). There was a significant interaction (P<0.001) between perceived stress and occupational status in relation to BP: perceived stress was negatively associated with high BP among individuals of high occupational status (OR: 0.91; 95% CI: 0.87-0.96), but positively associated among those of low status (OR: 1.10; 95% CI: 1.03-1.17) or unemployed (OR: 1.13; 95% CI: 1.03-1.24). Sensitivity analyses yielded similar results. The association between current perceived stress and BP depends on occupational status. This interaction may account for previous conflicting results and warrants further studies to explore its underlying mechanisms.

Health-related quality of life is worse in individuals with hypertension under drug treatment: results of population-based study. J Hum Hypertens 2011; 26:374-80.

Abstract
Patients with hypertension usually report lower health-related quality of life (HRQoL), but it is unclear whether this is secondary to high blood pressure (BP) per se, drug treatment or awareness of disease. In a cross-sectional study using a multistage population-based sample, participants were interviewed and examined at home. Hypertension was defined by BP ≥140/90 mm Hg or use of BP-lowering drugs. HRQoL was assessed through the Short-Form Health Survey (SF-12) and presented as the physical component summary (PCS), mental component summary (MCS) and the SF-12 eight-domain scale. In total, 1858 individuals were evaluated, being 60.1% women, aged 52.5 ± 4.1 years old, and 39.9% men, aged 47.2 ± 9.1 years old. Prevalence of hypertension was 34.2% (95% CI 31.5-36.9). The PCS scores for hypertensive and normotensive participants were 49.4 (CI 48.6-50.2) and 51.06 (CI 50.4-51.7) (P=0.01), respectively, and the MCS scores were 49.1 (CI 47.9-50.3) and 50.5 (CI 49.6-51.2) (P=0.06), respectively. Participants with hypertension and not using BP drugs had higher HRQoL scores (PCS 49.6; MCS 51.9) than those using BP drugs either with uncontrolled (PCS 45.3; MCS 49.4) or controlled BP (PCS 46.2; MCS 47.7; P<0.05). We concluded that individuals with hypertension have worse quality of life, particularly when their BP is controlled by drugs. This perception may lead to lower rates of adherence to treatment.

Abstract
OBJECTIVE Most, but not all cross-sectional surveys have identified lower quality of life among patients with hypertension. We summarized the estimates for this association in a systematic review and in a meta-analysis of cross-sectional studies. METHODS Studies that used the Short-Form Health Survey (SF) to compare the quality of life of normotensive and hypertensive individuals were searched in Embase, MEDLINE/PubMed, LILACS, Ovid, ScienceDirect, SciELO and Cochrane databases using 'hypertension' and 'quality of life' medical subject heading (MeSH) terms and the words 'health survey, SF-12, SF-36 and their spelling variations (SF12, SF 12, SF36 and SF 36)'. Data extraction was conducted by two researchers. Data were analyzed with MIX 1.7 using random effects model. Results of the meta-analysis were expressed as differences of mean scores between hypertensive and normotensive individuals. RESULTS Most of the 20 studies selected for the systematic review identified lower quality of life in patients with hypertension, but they were very heterogeneous in regard to selection criteria and comparison groups, limiting their external validity. The meta-analysis identified lower scores in hypertensive patients for physical [-2.43; 95% confidence interval (CI) -4.77 to -0.08] and mental (-1.68; 95% CI -2.14 to -1.23) components. Quality of life was lower in the eight domains of the SF-36: physical and functional functioning, role physical and emotional, bodily pain, general health, vitality and mental health. CONCLUSION Quality of life of individuals with hypertension is slightly worse than that of normotensive individuals. The influence of high blood pressure and of the awareness to have hypertension requires further investigation.

Abstract
OBJETIVO: Analisar a freqüência de hipertensão arterial sistêmica auto-referida e fatores associados. MÉTODOS: Estudo baseado em dados do sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL), coletados em 2006 nas capitais brasileiras e Distrito Federal. Estimou-se a freqüência de hipertensão arterial sistêmica entre 54.369 adultos, estratificada por sexo, região geográfica, variáveis sociodemográficas e comportamentais e morbidades auto-referidas. Foram calculadas os odds ratios brutos de hipertensão e ajustados para variáveis do estudo. RESULTADOS: A freqüência de hipertensão auto-referida foi de 21,6%, maior entre mulheres (24,4% versus 18,4%), menor nas regiões Norte e Centro-Oeste e maior na Sudeste. A freqüência de hipertensão aumentou com a idade, diminuiu com a escolaridade, foi maior entre negros e viúvos e menor entre solteiros. A chance de hipertensão, ajustada para variáveis de confusão, foi maior para os indivíduos com excesso de peso, diabetes, dislipidemia e de eventos cardiovasculares. CONCLUSÕES: Cerca de um quinto da população referiu ser portadora de hipertensão arterial sistêmica. As altas freqüências de fatores de risco modificáveis indicam os segmentos populacionais alvos de intervenção, visando à prevenção e controle da hipertensão.
