Abstract
AIMS Our main target was to investigate the relationship of blood pressure (BP) unawareness and poor antihypertensive drug adherence with the clinical outcomes of the stroke including hospitalization time, degree of disability, and mortality rate. METHODS AND RESULTS In this cross-sectional study, we evaluated 530 eligible patients (male = 313; female = 217), aged 18 years and older who had a proven diagnosis of nontraumatic first-ever stroke and were referred to the Shahid Beheshti Hospital of Hamadan, Iran, during the period from March 2019 to September 2021. The prevalence of BP unawareness was 19.6%, and 31.8% of antihypertensive drug users (14.3% of all studied population) had poor drug adherence, in which, older age, male gender, marriage, rural residence, and smoking were associated with the lack of appropriate drug adherence. There was no significant difference between patients with diverse stroke types (ischemic or hemorrhagic) from the points of BP awareness and adherence to antihypertensive drugs; nevertheless, patients with a positive history of cardiac diseases had a significantly higher awareness of their BP status ( P = 0.037). BP unawareness was associated with poor clinical prognosis, and could significantly increase stroke mortality ( P = 0.001) and disability ( P < 0.001) rates as well as the duration of hospitalization ( P < 0.001). Moreover, those who survived the stroke (modified Rankin Scale < 6) had the highest odds to be aware of their BP status (adjusted odds ratio [AOR] = 2.380 [95% confidence interval [CI] = 1.39-4.07]). Additionally, nonsmokers (AOR = 7.740), urban residents (AOR = 3.314), and literate patients (AOR = 2.092) had the highest odds of having appropriate drug adherence. CONCLUSION Stroke mortality and morbidity rates can be significantly modified by persuading people to monitor their BP regularly and maximize antihypertensive medication adherence. In the meantime, increasing the literacy level in society and reducing the smoking rate can play important roles in achieving these goals.

Pirasath S, Sundaresan T. Descriptive cross-sectional study on knowledge, awareness and adherence to medication among hypertensive patients in a tertiary care center, Eastern Sri Lanka. SAGE Open Med 2021; 9:20503121211012497. [PMID: 34017590 PMCID: PMC8114314 DOI: 10.1177/20503121211012497] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Accepted: 04/01/2021] [Indexed: 11/29/2022] Open
Abstract
Introduction: Hypertension is one of the common non-communicable diseases and public health problem among developed and developing countries. The lack of knowledge and awareness on hypertension and poor adherence of medication are a major challenge to control hypertension and prevent its complications. Our study aimed to assess the knowledge, awareness of hypertension and adherence to medication among hypertensive patients attending the medical clinics of a tertiary care center, Eastern Province of Sri Lanka. Methods: A descriptive cross-sectional study was conducted among hypertensive patients to assess knowledge, awareness of hypertension and adherence to medication in medical clinics in a tertiary care for 6 months duration. Data were collected by using pretested and validated Hypertension Facts Questionnaire. Their medication adherence and the reasons for nonadherence were studied using Medication Adherence Scale. Data were analyzed using SPSS (version 18) analytical package and the chi-square test was performed. The scoring system was used to categorize the level of knowledge and awareness of hypertension among patients. Results: The majority of patients had moderate-to-high knowledge (101, 65.8%) about hypertension and had moderate-to-high awareness (111, 73.2%) on hypertension. Even though, 134 (87.6%) patients knew that they have hypertension, and 108 (70.6%) patients did not know their blood pressure value at the time of diagnosis. Most of the patients (90, 58.8%) had good drug adherence, and most of them (141, 92.1%) thought that taking medicine plays a key role to control their blood pressure. The main reasons for nonadherence of medication were forgetfulness (39, 32%) and expenses (46, 35.4%). The knowledge and awareness about hypertension among respondents were significantly associated with educational level (p < 0.05) Conclusion: Most of the patients had adequate knowledge on the risk factors and complications of hypertension. But they were unaware about their disease status, and their diagnosis, target organ damage and recent blood pressure values. The drug adherence was reasonably adequate. The main reasons for nonadherence of medication were forgetfulness and expenses.

Int J Hypertens 2020; 2020:1320109. [PMID: 32832144 PMCID: PMC7422006 DOI: 10.1155/2020/1320109] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Revised: 06/10/2020] [Accepted: 06/23/2020] [Indexed: 12/03/2022] Open
Abstract
Objective This study was aimed to assess the patient's knowledge and awareness about hypertension and adherence to antihypertensive medication among hypertensive patients. Methods The descriptive cross-sectional study was conducted in three medical clinics of Colombo South Teaching hospital, Kalubowila, Sri Lanka, from April 2019 to September 2019. Total of 384 hypertensive patients were recruited by systematic randomized controlled sampling and interviewed with validated questionnaires to assess their knowledge about hypertension and adherence to antihypertensive medication. Data were analyzed using SPSS (version 21) analytical package, and the chi-squared test was performed. Results The total sample consisted of 384 hypertensive patients with a mean age of 59.32 (±12.34SD). This included 180 (46.9%) males and 204 (53.1%) females. The male : female ratio was approximately 9 : 10. Most of patients were with primary and ordinary educational status (65.9%), normal body mass index (54.9%), mild elevation of LDL cholesterol (76.3%), and coexistent ischemic heart disease (39.6%). The knowledge about hypertension among majority of patients was reasonable. However, they were unaware about normal values of blood pressure (69%, 95% of CI 1.92–2.09) and diagnostic values of hypertension (90.1%, 95% of CI 2.26–2.40). Moreover, they were unaware of their blood pressure values at time of diagnosis (75.3%, 95% of CI 2.09–2.25), at recent clinic visit (71.3%, 95% of CI 2.0-2.17), and target level (81.8%, 95% of CI 2.25-2.41). Most patients had adequate knowledge about the risk factors and complications of hypertension and were aware of their target organ damage (70.3%). Most patients believed that medication alone is not sufficient to control blood pressure (41.7%, 95% of CI 1.40-1.51) and adequate control of their blood pressure reduces complications (68.2%, 95% of CI 1.37-1.51). Most of the patients (71.8%) had reasonable good drug compliance. The forgetfulness was commonly attributed for nonadherence (69%, 95% of CI 1.26-1.36). Conclusions The knowledge about hypertension among majority of patients was reasonable. But, they were unaware about their disease status and their diagnosis, target, and recent blood pressure values. Most of patients had adequate knowledge about the risk factors and complications of hypertension. However, they were unaware about their target organ damage due to hypertension. The drug compliance was reasonable among them. The forgetfulness was common reason for nonadherence. Therefore, healthcare professionals should implement individualized educational programmes to increase the awareness of disease status, appropriate blood pressure levels, and adherence of treatment to improve the outcome of patients.

Abstract
Objective To assess the patient's knowledge and awareness about hypertension and adherence to antihypertensive medication among hypertensive patients with validated Morisky questionnaires in a tertiary care centre of northern Sri Lanka. Methods A cross-sectional descriptive comparative study was carried out at Teaching Hospital Jaffna, from January 2017 to April 2017. Hypertensive patients were recruited by systematic randomized controlled sampling and interviewed with validated Morisky questionnaires to assess their knowledge about hypertension. Data were analyzed using SPSS (version 21) analytical package. Results 73 of 303 patients were males. 69.9% of patients had adequate knowledge about hypertension. 40.5% of patients were unaware of their disease status. 75.8% of patients could not recall their blood pressure values at the time of diagnosis. 72.3% of patients were unaware of their values of blood pressure during their last outpatient clinic visit. 48.2% of patients had awareness of target organ damage due to hypertension (kidney, 72, 23.7%; heart, 128, 42.2%; brain, 140, 46.7%; eye, 42, 13.8%). Most of the patients had poor drug compliance. The most common reasons for nonadherence were forgetfulness (70, 23.1%) and interruptions of daily routine (53, 17.5%). Conclusion The knowledge about hypertension among majority of patients was reasonable. But they were unaware of their disease status. The drug compliance among them was poor. Forgetfulness and interruptions of daily routine were common reasons attributed for nonadherence.

Prevalent Long-Term Trends of Hypertension in Austria: The Impact of Obesity and Socio-Demography. PLoS One 2015; 10:e0140461.

Abstract
Background Globally there are only less long-term-studies on hypertension available to provide reliable estimates and identify risk groups. This study aims to analyse the prevalence and long-term-trend of hypertension in Austria, recognize affected subpopulations and investigate social inequalities. Methods This representative population-based study is based on self-reported data of adults (mean age: 47.7 ± 17.5; n = 178,818) that were taken from five health surveys between 1973 and 2007. An adjustment of self-reported BMI was performed based on a preliminary validation study. Absolute changes (AC) and aetiologic fractions (AF) were calculated from logistic regressions in order to measure trends. To quantify the extent of social inequality, a relative index of inequality (RII) was computed. Results During the study period the age-standardized hypertension prevalence increased from 1.0% to 18.8%, with a considerable rise from 1991 onwards. There was a positive trend in all subpopulations, with the highest AC among obese women (+50.2%) and obese subjects aged 75 years and older (+54.4%), whereas the highest risk was observed among the youngest obese adults (AF: 99.4%). The RII for hypertension was higher for women than men, but in general unstable during the investigation period. Conclusions Obesity and older age are significant factors for increased morbidity of hypertension. The most undesirable trends occurred in obese women and obese subjects aged 75 years and older. These risk groups should be given special attention when planning hypertension prevention programs. The high increase in the prevalence of hypertension is due to different aspects, e.g. a demographic change and a change in the definition of hypertension. These findings help to understand why hypertension is becoming more common in the Austrian population.

Abstract
BACKGROUND Misperceptions detract from effective disease management in a number of conditions but the nature of underlying illness beliefs and their relative consistency in patients with chronic hypertension (cHTN) who present to the Emergency Department (ED) with poor blood pressure control is not known. OBJECTIVES 1) To explore disease knowledge in ED patients with cHTN using explanatory modelling; and 2) to compare gaps in cHTN knowledge across racially similar but geographically divergent ED patients. METHODS Emergency department patients of African origin with cHTN were recruited from three sites: Detroit Receiving Hospital (DRH - Detroit, MI), the Tanzanian Training Center for International Health (TTCIH - Ifakara, TZ) and the University Hospital of the West Indies (UHWI - Kingston, JA). Demographic and baseline data were collected along with open-ended responses to a series of questions related to cHTN. Qualitative responses were coded into predefined, disease-relevant quantitative domains by two separate, blinded reviewers and multilevel comparisons were performed using Kruskal-Wallis or analysis of variance (ANOVA) tests, where appropriate. RESULTS One hundred and ninety-seven patients were enrolled; mean age (50.5 years vs 51.6 years vs 50.8 years; p = 0.86) and gender distribution (% male: 49.5 vs 44 vs 40; p = 0.53) were similar across sites but patients at DRH (vs TTCIH vs UHWI) were more hypertensive at presentation (mean systolic BP in mmHg: 166.8 vs 153 vs 152.7; p = 0.003), had a longer mean duration of cHTN (12.1 years vs 4.6 years vs 9.1; p < 0.0001), and were less likely to be on antihypertensive therapy (84.5% vs 92% vs 100%, p = 0.001). Explanatory models revealed limited recognition of cHTN as a "disease" (19.6% vs 28% vs 16%; p = 0.31) and consistency in the belief that cHTN was curable (44.3% vs 36% vs 42%; p = 0.62). Stress (48.4% vs 60% vs 50%; p = 0.31) and, especially at DRH, diet (62.2% vs 22% vs 36%; p < 0.0001) were identified most frequently as causes of cHTN and an association with symptoms was common (83.5% vs 98% vs 78%; p = 0.15). Clear differences existed for perceived benefits of treatment and consequences of poor control by site, but in general, both were under-appreciated. CONCLUSIONS Misperceptions related to cHTN are common in ED patients. While specific areas of disconnect exist by geographic region, failure to recognize cHTN as a dire and fixed disease state is consistent, suggesting that a uniform educational intervention may be of benefit in this setting.

Abstract
We assessed the differences in the knowledge and level of awareness of hypertension among patients with hypertension from Central Poland; 248 (57.6% females) patients diagnosed with hypertension completed a questionnaire. Most (79%) of the patients were unaware of the optimal blood pressure (BP) range. The elderly patients did not know the symptoms of hypertension (23.7%), were not willing to make lifestyle changes (57%-65%), and had a poor awareness of hypertension therapy in the absence of symptoms (28.7%). Poor BP control occurred mainly in rural residents (10.7%) and in people with higher education (39.3%). Untreated patients with hypertension did not know the symptoms of hypertension (29.2%), rarely measured BP (37.5%), but were more likely to engage in regular physical activity (70.8%). Efforts should be made to improve knowledge of hypertension, especially among the rural population, the elderly patients, those with a low-education level, and in young males who had the highest BP.

Abstract
BACKGROUND Blood pressure (BP) awareness is a main focus of public health efforts. In Austria, an increase of knowledge and perception regarding hypertension was seen after a nationwide educational campaign in 1978, but subsequent surveys documented only short-term impact. We report results of the latest survey in 2009 in comparison to 1978 and 1998. METHODS Balanced for Austrian demographic characteristics 1,005 men and women older than 15 years of age were randomly selected for face-to-face interviews about BP awareness, risk factors, and hazards of hypertension and treatment options including life-style interventions. RESULTS Overall, 15% identified themselves as hypertensive, which is similar to results from 1978 (14%) but significantly higher than 1998 (12%; P < 0.01). The proportion of hypertensives not undertaking any measure (i.e., pharmacotherapy or life-style changes) significantly decreased since 1998 (5% vs. 10%; P < 0.0001). Thirty-three percent recalled to have measured their BP within the last 3 months, which is comparable to 1998 (34%) but lower than in 1978 (49%) after the nationwide educational BP campaign (P < 0.0001). Alarmingly, an unchanged proportion of 8% reported no BP measurement ever (1978 and 1998: 8%, respectively). Sixty-one percent believed they would be able to clearly identify symptoms of hypertension, while only 19% knew that hypertension might not be noticeable. Heart attack and stroke were considered the most common sequelae of hypertension. CONCLUSION Despite a high understanding of the risks of hypertension among the Austrian population, a widespread misconception regarding BP symptoms and infrequent personal checks are worrisome and might also be valid in other Western countries.

Abstract
Knowledge of population distribution of blood pressure is useful for predicting blood pressure related health burden as well as for planning prevention strategy. The aim of this investigation is to determine the distribution of systolic blood pressure (SBP), diastolic blood pressure (DBP), arterial blood pressure (ABP), and heart rate among normotensive adults resident from all regions of Jordan. This study is the first detailed description of these parameters in Jordan at a national level. A total of 14,310 adult males (7,400) and females (6,910) were selected randomly in various regions of Jordan. For each individual, the SBP, DBP, and heart rate were measured three times with 10-15-minute intervals in the sitting position and at the resting state. The ABP was calculated from the measured SBP and DBP. The mean values were distributed according to age and sex. Student's t-test was used for statistical analysis. Males had significantly higher SBP, DBP, ABP, and heart rate values than females. There also was an increase of these values with advancing age. Moreover, cases of hypotension and bradycardia were higher in the female population than in males, whereas cases of hypertension and tachycardia were higher in males. Distribution of blood pressure and heart rate among adults in Jordan was determined. Cases of undiagnosed hypertension, hypotension, and an increase or a decrease in heart rate were detected through our random screening in the target population. Individuals with these abnormalities require further clinical investigations to confirm or exclude these findings.

Abstract
Regular blood pressure (BP) measurements are required to identify people with hypertension and to optimally manage their cardiovascular risk. Analyses of data from the 2000-2001 Canadian Community Health Survey showed that most adult Canadians have had a BP assessment in the previous 2 years and few have never had one. Large numbers of persons without BP recordings were observed, however, among persons who were younger, were male, who did not have either a regular doctor or physician contact in the previous year, who were recent immigrants or visible minorities (nonwhite and non-Aboriginal), and who spoke neither French nor English. Common reasons reported for not having a BP assessment included believing it was not necessary and simply not getting around to it. Education programs targeting those at risk as well as more convenient BP screening may improve awareness and testing.

Abstract
This article uses census records and deaths records to analyze trends in educational inequalities in mortality for Austrian women and men aged 35-64 years between 1981/1982 and 1991/1992. We find an increasing gradient in mortality by education for circulatory diseases and especially ischaemic heart disease. Respiratory diseases and, in addition for women, cancers showed the opposite trend. Using decomposition analysis, we give evidence that in many cases changes in the age-structure within the 10-year interval had a bigger effect than direct improvements in mortality on the analyzed subpopulations.

Abstract
STUDY OBJECTIVES The aim of this study was to examine the extent of the general public's knowledge concerning HDL-cholesterol and to identify the role of gender, age, population size of the locality and socio-economic factors. DESIGN Cross-sectional population-based telephone survey. SETTING Austrian general population. PARTICIPANTS Nine hundred and ninety nine subjects aged 16 years or over, randomly selected from the official telephone directory in Austria. MAIN RESULTS 13.9% of the 999 participants were familiar with the term HDL-cholesterol, correctly identified HDL-cholesterol as the favourable cholesterol component and indicated that HDL-cholesterol should be high rather than low. Knowledge of HDL-cholesterol increased with population size of the locality, total net income of the household and educational level. Respondents in bigger localities had their HDL-cholesterol measured more frequently. Older people and males reported making significantly more attempts to positively influence their HDL-cholesterol level. 29.6% of those respondents familiar with the term HDL-cholesterol reported having had their HDL-cholesterol measured at some point. Physicians, newspapers and television were identified as the most important sources of information on HDL-cholesterol by 79.7, 19.9 and 10.3% of the study subjects, respectively. CONCLUSIONS Although measuring HDL-cholesterol plays a major role in the assessment of cardiovascular risk, public knowledge about HDL-cholesterol is scarce.

Abstract
OBJECTIVE Improved recognition of the importance of systolic blood pressure (SBP) has been identified as one of the major public health and medical challenges in the prevention and treatment of hypertension (HTN). SBP is a strong independent risk factor for cardiovascular disease but no information is available on whether patients understand the importance of their SBP level. The purpose of this study was to assess HTN knowledge, awareness, and attitudes, especially related to SBP in a hypertensive population. DESIGN/SETTING/PATIENTS We identified patients with HTN (N=2,264) in the primary care setting of a large midwestern health system using automated claims data (International Classification of Diseases, Ninth Revision [ICD-9] codes 401.0-401.9). We randomly selected 1,250 patients and, after excluding ineligible patients, report the results on 826 completed patient telephone interviews (72% response rate [826/1,151]). MAIN RESULTS Ninety percent of hypertensive patients knew that lowering blood pressure (BP) would improve health and 91% reported that a health care provider had told them that they have HTN or high BP. However, 41% of patients did not know their BP level. Eighty-two percent of all patients correctly identified the meaning of HTN as "high blood pressure." Thirty-four percent of patients correctly identified SBP as the "top" number of their reading; 32% correctly identified diastolic blood pressure (DBP) as the "bottom" number; and, overall, only 30% of patients were able to correctly identify both systolic and diastolic BP measures. Twenty-seven percent of patients with elevated SBP and DBP (as indicated by their medical records) perceived that their BP was high. Twenty-four percent of patients did not know the optimal level for either SBP or DBP. When asked whether the DBP or SBP level was more important in the control and prevention of disease, 41% reported DBP, 13% reported SBP, 30% reported that both were important, and 17% did not know. CONCLUSIONS These results suggest that, although general knowledge and awareness of HTN is adequate, patients do not have a comprehensive understanding of this condition. For instance, patients do not recognize the importance of elevated SBP levels or the current status of their BP control. An opportunity exists to focus patient education programs and interventions on the cardiovascular risk associated with uncontrolled HTN, particularly elevated SBP levels.

Abstract
STUDY OBJECTIVE To assess period and point prevalence of headache in Austria and the influence of sociodemographic factors and seasonal variations. DESIGN Data for the prevalence of headache were drawn from the database of seven representative surveys in the SERMO study (Self-Reported Morbidity Study). The aims of the SERMO study are to describe and monitor the characteristics of background morbidity in the Austrian population. The study is based on face-to-face interviews. Headache/migraine was one of 36 disorders the interviewed persons were asked about. SETTING The representative samples of the Austrian general population were selected by the "quota-procedure". Thus each cross sectional sample is representative for the entire Austrian population. PARTICIPANTS The study population consisted of 7,162 Austrian people over 15 years of age. RESULTS About one fifth (20.1%) of the Austrian adult population reported having headaches during the year (prevalence 26.4% in women vs. 13.0% in men, p<0.001). Period prevalences varied from 19.6% in August to 23.1% in October 1995. Mean point prevalence in the general population was 5.7% (3.6% in men vs. 7.7% in women, p<0.001). The highest point prevalence (8.0%) was observed among people over 60. Whereas period prevalence showed no trend with age or education, we found increasing point prevalence with age and lower levels of education. In general, significantly more people with self-reported headache suffered from stress (39.1% vs. 33.7%, p<0.001) and chronic diseases (33.6% vs. 23.2%, p<0.001) and took drugs regularly (all kinds of medication: 44.3% vs. 26.8%, p<0.001). CONCLUSIONS Headache is one of the most commonly experienced symptoms in Austria. The most common concomitant disease in the study population as a whole was hypertension. People with headache had a higher prevalence of hypertension, rheumatic diseases, venous diseases, diabetes and a higher consumption of drugs. Therefore, headache, as one aspect of multimorbidity or a symptom of other diseases, could be an indicator of impaired well-being and poor health.

Abstract
OBJECTIVES To determine prevalence, awareness, treatment, and control of hypertension, and its risk factors in an urban Korean population. DESIGN AND SETTING A cross-sectional survey in Ansan-city, Korea. SUBJECTS AND METHODS Population-based samples of people aged 18-92 years in Ansan-city, Korea, were selected, yielding 2278 men and 1948 women, and their blood pressures were measured using a highly standardized protocol. Hypertension was defined as a systolic BP > or = 140 mmHg or diastolic BP > or = 90 mmHg or reported treatment with antihypertensive medications, and subclassified according to 1999 WHO-ISH guidelines. Isolated systolic hypertension (ISH) defined as a systolic BP > or = 140 mmHg and diastolic BP < 90 mmHg was also examined. Data were stratified by age and sex. RESULTS The overall prevalence of hypertension in this study was 33.7%. Among these, 64.9% had Grade 1 hypertension, 22.5% Grade 2, and 12.5% Grade 3. Age-specific prevalence of hypertension increased progressively with age, from 14.19% in 18 to 24 year-olds to 71.39% in those 75 years or older. Hypertension prevalence was significantly higher in men (41.5%) than in women (24.5%) (P < 0.001). Isolated systolic hypertension had significantly lower prevalence (4.33%) within the population, although in the elderly aged 55 years or more it rose by 11.13%. Overall, 24.6% of hypertensive individuals were aware that they had high blood pressure, as much as 78.6% were being treated with antihypertensive medications, and 24.3% were under control. Hypertension awareness as well as treatment and control rates varied by sex, with women higher in all three rates. Multivariate analysis revealed that age, body mass index and abdomen circumference were significantly associated with prevalence of hypertension both in men and women. CONCLUSIONS Hypertension is highly prevalent in Korea. Despite the high rate of treatment, the rates of awareness and control are relatively low, suggesting the nationwide demand for preventing and controlling high blood pressure in Korea in order to avert an epidemic of cardiovascular disease.
