Determinants of blood pressure control amongst hypertensive patients in Northwest Ethiopia

Uncontrolled hypertension among hypertensive patients in Sub-Saharan Africa: A systematic review and meta-analysis

INTRODUCTION

Hypertension is a major global public health problem. It currently affects more than 1.4 billion people worldwide, projected to increase to 1.6 billion by 2025. Despite numerous primary studies have been conducted to determine the prevalence of uncontrolled hypertension and identify its associated factors among hypertensive patients in Sub-Saharan Africa, these studies presented inconsistent findings. Therefore, this review aimed to determine the pooled prevalence of uncontrolled hypertension and identify its associated factors.

METHODS

We have searched PubMed, Google Scholar, and Web of Science databases extensively for all relevant studies. A manual search of the reference lists of included studies was performed. A weighted inverse-variance random-effects model was used to compute the overall pooled prevalence of uncontrolled hypertension and the effect size of its associated factors. Variations across the included studies were checked using forest plot, funnel plot, I2 statistics, and Egger's test.

RESULTS

A total of twenty-six primary studies with a sample size of 11,600 participants were included in the final meta-analysis. The pooled prevalence of uncontrolled hypertension was 50.29% (95% CI: 41.88, 58.69; I2 = 98.98%; P<0.001). Age of the patient [AOR = 1.57: 95% CI: 1.004, 2.44], duration of diagnosis [AOR = 2.57: 95% CI: 1.18, 5.57], non-adherence to physical activity [AOR = 2.13: 95% CI: 1.15, 3.95], khat chewing [AOR = 3.83: 95% CI: 1.59, 9.24] and habitual coffee consumption [AOR = 10.79: 95% CI: 1.84, 63.24] were significantly associated with uncontrolled hypertension among hypertensive patients.

CONCLUSIONS

The pooled prevalence of uncontrolled hypertension was considerably high. Older age, duration of diagnosis, non-adherence to physical activity, khat chewing and habitual coffee consumption were independent predictors of uncontrolled hypertension. Therefore, health professionals and other responsible stakeholders should encourage hypertensive patients to adhere to regular physical activity, and abstain from khat chewing and habitual coffee consumption. Early identification of hypertension and management of comorbidities is crucial, and it should be emphasized to control hypertension easily.

Blood pressure and the hypertension care cascade in The Gambia: Findings from a nationwide survey

Community treatment of hypertension in sub-Saharan Africa is hampered by gaps at several stages of the care cascade. We compared blood pressure (BP) levels (systolic, diastolic and pulse pressures) in four groups of participants by hypertension and treatment status. We conducted a nationally representative survey of adults 35 years and older using a multistage sampling strategy based on the 2013 Gambia Population and Housing Census. The BP measurements were taken in triplicate 5 min apart, and the average of the last two measurements was used for analysis. Systolic and diastolic BP levels and pulse pressure were compared by hypertension status using mean and 95% confidence intervals (CI). 53.1% of the sample were normotensive with mean systolic BP (SBP) of 119.2 mmHg (95% CI, 118.7-119.6) and diastolic BP (DBP) of 78.1 mmHg (77.8-78.3). Among individuals with hypertension, mean SBP was 148.7 mmHg (147.7-149.7) among those unaware of their hypertension, 152.2 mmHg (151.0-153.5) among treated individuals and was highest in untreated individuals at 159.3 mmHg (157.3-161.2). The findings were similar for DBP levels, being 93.9 mmHg (93.4-94.4) among the unaware, 95.1 mmHg (94.4-95.8) among the treated and highest at 99.1 mmHg (98.1-100.2) in untreated participants. SBP and DBP were higher in men, and SBP was as expected higher in those aged ≥55 years. BP level was similar in urban and rural areas. Our data shows high BP levels among participants with hypertension including those receiving treatment. Efforts to reduce the health burden of hypertension will require inputs at all levels of the care cascade.

Prevalence of uncontrolled hypertension and contributing factors in Ethiopia: a systematic review and meta-analysis

Background

Uncontrolled hypertension (HTN) is a major risk factor for cardiovascular and cerebrovascular disease. The prevalence of HTN in the Ethiopian adult population is almost 20%.This study aimed to determine the prevalence of uncontrolled HTN and its contributing factors among patients with HTN in Ethiopia undergoing treatment.

Methods

Electronic bibliographic databases such as PubMed, Google Scholar, Hinari (Research4Life), Embase, and Scopus were searched for original records in the English language that assessed HTN control in Ethiopia and were available before 29 June 2023. The data were extracted using a format prepared in Microsoft Excel and exported to the software STATA 17.0 for analysis. The study protocol was registered at PROSPERO with the reference number CRD42023440121.

Results

A total of 26 studies with 9,046 patients with HTN were included in the systematic review and meta-analysis, of which 11 studies were used to assess factors contributing to uncontrolled blood pressure (BP) in patients in Ethiopia. The estimated prevalence of uncontrolled HTN in the population of Ethiopia is 51% [95% confidence interval (CI), 42%-60%]. The subgroup analysis, based on the assessment tools, region, and follow-up period, revealed that the prevalence of uncontrolled BP was highest following the guidelines of the American Heart Association/American College of Cardiology (AHA/ACC) (89%; 95% CI: 87%-91%) and in Addis Ababa (58%; 95% CI: 40%-76%), and the lowest proportion of uncontrolled BP was in the 3-month follow-up period (34%; 95% CI: 29%-39%). The presence of diabetes mellitus showed the highest impact (pooled odds ratio: 5.19; CI: 1.41-19.11) for uncontrolled HTN. The univariate meta-regression method confirmed that the sample size, year of publication, and subgroups were not sources of heterogeneity in the pooled estimates. Egger's regression test did not indicate the presence of publication bias.

Conclusion

More than half of the hypertensive patients in Ethiopia have uncontrolled BP. Diabetes mellitus, advanced age, male sex, and the presence of comorbidities are among the factors contributing to uncontrolled HTN in Ethiopia. The concerned bodies working in this area should implement interventional strategies and recommendations that might be helpful in achieving optimal BP in hypertensive patients.

The prevalence and determinants of blood pressure control among hypertension patients in eastern Zimbabwe: A cross-sectional study

BACKGROUND

Uncontrolled blood pressure (BP), also known as hypertension, is a leading cause of morbidity and mortality globally. Lowering the elevated BP can significantly reduce one's risk for cardiovascular diseases. This study aimed to ascertain the determinants of BP control among hypertension patients.

METHODS

The data analyzed were from the exploratory survey of the Home Management of Hypertension (HoMHyper) project in eastern Zimbabwe. Hypertension patients were selected from the Chronic Disease Registers of five public health clinics using simple random sampling. A pretested interviewer-administered questionnaire was used to collect data, and the patient's BP was measured. The primary outcome, BP control, was used as a categorical variable (controlled vs. uncontrolled) to conduct a bivariate analysis. Variables significant at p<0.2 were included in the multivariable logistic regression analysis to control for confounding. Statistical significance in the final model was set at p<0.05.

RESULTS

Data from 321 hypertension patients were analyzed; their mean age was 62.3±11.9 years. The prevalence of controlled BP was 41.4% (95% Confidence interval-CI = 36.0%-46.9%). After adjusting for confounding, patients' residence and medication stocks were associated with BP control. Patients who resided in high-density suburbs had higher odds of uncontrolled BP than those who resided in middle- and low-density suburbs (Adjusted odds ratios-AOR = 2.5; 95% CI = 1.4-4.4; p<0.01). Hypertension patients who experienced medication stockouts over the last six months had higher odds of uncontrolled BP than patients who did not experience stockouts (AOR = 1.8; 95% CI = 1.1-2.9).

CONCLUSION

BP control among hypertension patients was suboptimal. Patient residence and antihypertensive medication stockouts were independent predictors of blood pressure control. We recommend exploring sustainable financing through private-public partnerships to ensure the availability of subsidized antihypertensive medication.

Risk factors for uncontrolled blood pressure among individuals with hypertension on treatment: the CONSTANCES population-based study

BACKGROUND

We aimed to assess factors associated with uncontrolled blood pressure (BP) among individuals with hypertension on treatment, by sex.

METHODS

We conducted a nested cross-sectional analysis using data from the population-based cohort study CONSTANCES, designed as a randomly selected sample of French adults aged 18-69 years at study inception. We included 11 760 participants previously diagnosed with hypertension and taking antihypertensive medications. Uncontrolled BP was defined as mean systolic BP ≥140 mmHg and/or mean diastolic BP ≥90 mmHg. Sex-specific age-adjusted multivariable analyses were performed using logistic regression models stratified by stages of uncontrolled hypertension.

RESULTS

The mean age of participants was 59.4 years. The prevalence of uncontrolled BP was 51.4%, and it was higher in men than in women [adjusted odds ratio (aOR), 1.80; 95% CI, 1.67-1.94]. In both sexes, the lower the age, the lower the prevalence of uncontrolled hypertension. Low level of education and history of cardiovascular events had, respectively, higher and lower odds of uncontrolled BP. In men, additional risk factors included overweight and obesity (aOR, 1.15; 95% CI, 1.00-1.32; and aOR, 1.45; 95% CI, 1.23-1.70, respectively), lack of physical activity (aOR, 1.20; 95% CI, 1.04-1.40), low adherence to a Dietary Approach to Stop Hypertension diet (aOR, 1.21; 95% CI, 1.05-1.40) and heavy alcohol consumption (aOR, 1.33; 95% CI, 1.08-1.63), with the last two factors persisting across different stages of uncontrolled BP.

CONCLUSIONS

From a population-based perspective, socio-economic and behavioural characteristics were risk factors for uncontrolled hypertension, but they differed by sex and by stage of uncontrolled hypertension. Modifiable risk factors, such as weight, diet, physical activity and alcohol consumption, have an important role in the control of hypertension.

Adherence Behaviors and Related Factors Among Elderly Hypertensive Patients in China: Evidence from the China Health and Retirement Longitudinal Study

Background

Non-adherence or partial adherence is the main reason for poor therapeutic effect of hypertension. This paper aims to assess adherence behaviors and related factors among elderly hypertensive patients in China.

Methods

Participants aged ≥60 years, with hypertension, and with complete data in 2018 interviews of the China Health and Retirement Longitudinal Study (CHARLS) were included. The adherence behaviors included medication, blood pressure monitoring and the combined adherence behaviors. Referring to the social-ecological theory, correlates of adherence behaviors were divided into three layers, namely demographic characteristics, health behaviors, living environment and retirement. Univariate and multivariable logistic regression models were performed to identify factors of adherence behaviors.

Results

The prevalence of medication adherence (76.58%) was higher than that of blood pressure monitoring adherence (20.08%), and the full adherence rate was 18.53%. Self-rated health status, smoking status, living area, and health education status were detected to be associated with medication adherence and blood pressure monitoring adherence (all p < 0.05). Gender, sleep duration, health examination, and physical exercise were also detected to be associated with blood pressure monitoring adherence (all p < 0.05). Self-rated health status and health education status were detected to be associated with partially and fully adherence, while age, living area, and life satisfaction were detected to be associated with partially adherence, smoking status, sleep duration, health examination, and pension reliance were detected to be associated with fully adherence (all p < 0.05).

Conclusion

Our study reveals the poor adherence behaviors of elderly hypertensive patients in China. This is most evident among those who were male, 60-69 years old, living in rural areas, self-reported being healthier, those without health examination and health education. Targeting these vulnerable populations, we suggest to strengthen health education, increase the publicity of basic public health services and enhance the self-management ability of hypertensive patients.

Uncontrolled Hypertension, Treatment, and Predictors among Hypertensive Out-Patients Attending Primary Health Facilities in Johannesburg, South Africa

Hypertension is a poorly controlled risk factor for cardiovascular disease in South Africa, particularly among patients receiving care in the public sector who are mostly from low socioeconomic backgrounds. This cross-sectional study investigated uncontrolled hypertension, treatment, and predictors among hypertensive out-patients attending primary health care facilities in Johannesburg, South Africa. The WHO STEPwise approach to the surveillance of non-communicable diseases was used to collect data, including sociodemographic and lifestyle factors, health status, and measurements for anthropometry and blood pressure along with self-reported adherence to treatment, estimated through the general medication adherence scale. Uncontrolled hypertension was defined as systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg in diagnosed patients receiving anti-hypertensive treatment. Overweight and obesity were defined as a body mass index ≥25 and ≥30 kg/m2, respectively. Logistic regression models were used to assess the predictors of uncontrolled hypertension. Four hundred (n = 400) hypertensive out-patients (mean age: 50 ± 8 years) participated in this study, with most living in poor sociodemographic environments. The prevalence rate of uncontrolled hypertension was 57%. Obesity (62% vs. 42%, p ≤ 0.0001), salt consumption (90% vs. 55%, p ≤ 0.0001), alcohol intake (42% vs. 19%, p ≤ 0.0001), a smoking habit (23% vs. 4%, p ≤ 0.0001), alternative medicine use (51% vs. 40%, p = 0.043), and comorbidities (64% vs. 36%, p ≤ 0.0001) were higher in the uncontrolled group than the controlled group, whereas the prevalence of physical activity (38% vs. 15%, p ≤ 0.0001) was high in the controlled group vs. the uncontrolled. Overall, 85% of the patients moderately adhered to treatment, only 2% exhibited high adherence, and 13% demonstrated low adherence; over half of the patients received tri-therapy treatment. The predictors of uncontrolled hypertension are a number of prescribed antihypertensive therapies [adjusted odds ration = 2.39; 95% confidence interval: 1.48-3.87], treatment adherence [0.46; 0.21-0.97], salt consumption [28.35; 7.87-102.04], physical activity [0.22; 0.13-0.37], current alcohol use [2.10; 1.22-3.61], and current cigarette smoking [4.79; 1.88-12.18]. The high prevalence of uncontrolled hypertension in this study suggests a need to optimize prescriptions, adherence to BP-lowering medications, and lifestyle modifications. The management of comorbidities such as diabetes could offer considerable benefits in controlling blood pressure.

Physical activity level and sedentary time determinants among Moroccan hypertensive patients

INTRODUCTION

Hypertension is closely associated with an inactive lifestyle. Physical activity and/or exercise have been shown to delay the development of hypertension. This study aimed to assess the level of physical activity and sedentary time, and its determinants among Moroccan Hypertensive patients.

PATIENTS AND METHODS

A cross-sectional study was conducted between March and July 2019 including 680 hypertensive patients. We administered international physical activity questionnaire in face-to-face interview to assess the level of physical activity and sedentary time.

RESULTS

The results showed that only 43.4% of participants met recommended physical activity levels (≥ 600 MET min/week). Adherence to physical activity recommendations was observed more in male participants (p = 0.035), in participants aged less than 40 years (p = 0.040) and those aged between 41 and 50 years (p = 0.047). The average sedentary time was 37.19 ± 18.92 hours per week. This time was significantly longer in people aged 51 and over, in married, divorced, and widowed people, and in those with low levels of physical activity.

CONCLUSIONS

The level of physical inactivity and the sedentary time was high. In addition, participants with a high-level sedentary lifestyle had a low level of physical activity. Educational actions should be undertaken among this group of participants to prevent the risks associated with inactivity and sedentary behavior.

Determinants of blood pressure control among hypertensive patients of rural areas in a South Indian State: A community based cross sectional study

Introduction

Optimum blood pressure (BP) control is essential to prevent complications and improve the quality of life of patients with hypertension. This study aimed to explore the determinants of BP control in patients with hypertension on treatment without any other comorbidities.

Method

The study was conducted among 429 patients with essential hypertension aged > 30 years residing in four villages of a taluk/tahsil in a South Indian state. A pre-tested semi-structured questionnaire was used to collect data on socio-demographic characteristics, diagnosis and treatment of hypertension, lifestyle factors (e.g. diet and substance use), facilitators and barriers of BP control and anthropometric measurements. BP was measured using World Health Organization standards and classified using the Joint National Committee 8 Guidelines. Descriptive statistics were measured in terms of numbers and percentages. Univariate and multivariate logistic regression analyses were used to determine the significant determinants of BP control.

Results

Approximately 64.3% of the participants had their BP under control. The participants aged 46-59 years were more likely to have uncontrolled BP than those aged ≥60 years. The participants with <80% adherence to medication (non-adherent) had a five fold higher odds of having uncontrolled BP than those with >80% adherence.

Conclusion

Adherence to medication was the only significant factor for BP control in the present study. Hence, adherence to medication should be addressed with interventions targeted to improve BP control in patients with hypertension.

Undiagnosed hypertension and associated factors among adults in ethiopia: a systematic review and meta-analysis

BACKGROUND

Hypertension is a major public health problem, resulting in 10 million deaths annually. Undiagnosed hypertension affects more people than ever before. It is more likely to be linked to severe hypertension, which can lead to stroke, cardiovascular disease, and ischemic heart disease. Thus, this systematic review and meta-analysis aimed to synthesize the prevalence of undiagnosed hypertension and its associated factors in Ethiopia.

METHODS

Databases, such as Medline/PubMed, Google Scholar, Science Direct, AJOL, and the Cochrane Library, were systematically searched to find potential studies published until December 2022. A Microsoft Excel spreadsheet was used to enter the extracted data. The pooled prevalence of undiagnosed hypertension and its associated factors was estimated using a random effect model. I2 statistics and the Cochrane Q-test were used to assess statistical heterogeneity across the studies. Begg's and Egger's tests were performed to identify possible publication bias.

RESULTS

A total of ten articles with 5,782 study participants were included in this meta-analysis. In the random effects model, the pooled prevalence of undiagnosed hypertension was 18.26% (95% CI = 14.94-21.58). Being older (OR = 3.8, 95% CI = 2.56, 5.66), having a body mass index > 25 kg/m2 (OR = 2.71, 95% CI = 2.1, 3.53), having a family history of hypertension (OR = 2.22, 95% CI = 1.47, 3.36), and having DM comorbidity (OR = 2.44, 95% CI = 1.38, 4.32) were significantly associated with undiagnosed hypertension.

CONCLUSION

In this meta-analysis, the pooled prevalence of undiagnosed hypertension was found to be high in Ethiopia. Being older, having a BMI > 25 kg/m2, having a family history of hypertension, and having DM comorbidity were found to be risk factors for undiagnosed hypertension.

Uncontrolled blood pressure and associated factors in adult hypertensive patients undergoing follow-up at public health facility ambulatory clinics in Bishoftu town, Ethiopia: a multi-center study

BACKGROUND

Uncontrolled blood pressure is an important medical and public health problem in developing countries like Ethiopia. Improving the management of hypertension requires a better comprehension of the factors influencing blood pressure control and the application of interventions. But in clinical practice, blood pressure is still not adequately controlled. Thus, this study aimed to assess uncontrolled blood pressure and associated among adult hypertensive patients on follow-up at public health facility ambulatory clinics in Bishoftu, Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted among 398 adult hypertensive patients who were on treatment and follow-up from April to May 31, 2022. Systematic random sampling was used to select study participants. Data were collected using an interviewer-administered, semi-structured questionnaire and chart review. The Eighth Joint National Committee (JNC 8) criteria was applied to define blood pressure control status. Binary logistic regression analysis was used to model the association between dependent and independent variables. An adjusted odds ratio and 95% confidence interval were used to measure the strength of the association. Finally, at a p-value < 0.05, statistical significance was proclaimed.

RESULT

Of the total study participants, 249(62.6%) were male. The mean age was 62.26 ± 11.55 years. The overall proportion of uncontrolled blood pressure was 58.8% (95% CI: 54-64). Salt intake (AOR = 2.51; 95% CI: 1.49-4.24), lack of physical activity (AOR = 1.40; 95% CI: 1.10-2.62), habitual coffee consumption (AOR = 4.52; 95% CI: 2.67-7.64), higher BMI (AOR = 2.08; 95% CI: 1.24-3.49), and non-adherence to antihypertensive medications (AOR = 2.31; 95% CI: 1.3-3.89) were independent predictors of uncontrolled blood pressure.

CONCLUSION

More than half of the hypertensive patients in this study had uncontrolled blood pressure. Healthcare providers and other accountable stakeholders should urge patients to follow salt restriction, physical activity, and antihypertensive medication regimes. Reduced coffee consumption and weight maintenance are other crucial blood pressure control measures.

Joint modeling of longitudinal changes of blood pressure and time to remission of hypertensive patients receiving treatment: Bayesian approach

INTRODUCTION

Hypertension is a widespread condition when the blood's force on the artery walls is extremely high to develop adverse health effects. This paper aimed to jointly model the longitudinal change of blood pressures (systolic and diastolic) and time to the first remission of hypertensive outpatients receiving treatment.

METHODS

A retrospective study design was used to collect appropriate data on longitudinal changes in blood pressure and time-to-event from the medical charts of 301 hypertensive outpatients under follow-up at Felege Hiwot referral hospital, Ethiopia. The data exploration was done using summary statistics measures, individual profile plots, Kaplan-Meier plots, and log-rank tests. To get wide-ranging information about the progression, joint multivariate models were employed.

RESULTS

A total of 301 hypertensive patients who take treatment was taken from Felege Hiwot referral hospital recorded between Sep. 2018 to Feb. 2021. Of this 153 (50.8%) were male, and 124 (49.2%) were residents from rural areas. About 83(27.6%), 58 (19.3%), 82 (27.2%), and 25 (8.3%) have a history of diabetes mellitus, cardiovascular disease, stroke, and HIV respectively. The median time of hypertensive patients to have first remission time was 11 months. The hazard of the patient's first remission time for males was 0.63 times less likely than the hazard for females. The time to attain the first remission for patients who had a history of diabetes mellitus was 46% lower than for those who had no history of diabetes mellitus.

CONCLUSION

Blood pressure dynamics significantly affect the time to the first remission of hypertensive outpatients receiving treatment. The patients who had a good follow-up, lower BUN, lower serum calcium, lower serum sodium, lower hemoglobin, and take the treatment enalapril showed an opportunity in decreasing their blood pressure. This compels patients to experience the first remission early. Besides, age, patient's history of diabetes, patient's history of cardiovascular disease, and treatment type were the joint determinant factors for the longitudinal change of BP and the first remission time. The Bayesian joint model approach provides specific dynamic predictions, wide-ranging information about the disease transitions, and better knowledge of disease etiology.

Family support and medication adherence among residents with hypertension in informal settlements of Nairobi, Kenya: a mixed-method study

Suboptimal medication adherence is a major barrier to hypertension control in Kenya, especially among informal urban settlement areas (sometimes referred to as "slums"). The few studies that have specifically explored medication adherence among this population have received discordant results, implying that additional factors which influence medication adherence merit further investigation. This study explores the relationship between family support and medication adherence among people with hypertension in informal settlements in Nairobi, Kenya. We conducted a quantitative survey followed up by semi-structured qualitative interviews. The sampling frame comprised two health facilities in informal settlement areas of the Korogocho neighborhood and participants were recruited via convenience sampling. We performed multiple logistic regressions for quantitative data and thematic analysis for qualitative data. A total of 93 people participated in the survey (mean age: 57 ± 14.7, 66% female). Most participants reported high family support (82%, n = 76) and suboptimal medication adherence (43% by the Morisky Scale; 76% by the Hill-Bone Scale), with no significant associations between family support and medication adherence. During interviews, many participants reported they lacked health knowledge and education. We suggest that the lack of health knowledge among this population may have contributed to a failure for family support to meaningfully translate into improvements in medication adherence. Our results underscore the need for further research to improve hypertension control among this uniquely disadvantaged population, especially with respect to the possible mediating influence of health education on family support and medication adherence.

Uncontrolled Hypertension and Behavioral Risk Factors among Adult Hypertensive Patients at Saint Paul’s Hospital, Millennium Medical College, Addis Ababa, Ethiopia

Introduction. Uncontrolled hypertension is a state of systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg even though the patients are on antihypertension. The WHO states that it is the most prevalent risk factor for death and disability worldwide, particularly in developing nations. The goal of the current study was to investigate behavioral risk factors for uncontrolled hypertension among adult hypertensive patients in Ethiopia. Methods. From October to November 2020, a cross-sectional study design was carried out in the hypertension follow-up clinic at Saint Paul’s Hospital, Millennium Medical College. The choice of 474 study participants was made using a straightforward random sampling method. A semistructured questionnaire was used to obtain data through a chart review as well as an interview. The data were coded before being imported into Epi-data version 7.0 and exported to SPSS version 25 for analysis. To determine the factors associated with uncontrolled hypertension, a multivariate logistic regression model (AOR, 95% CI, and $p$ value 0.05) was used. Result. This study found that 52.1% of hypertensive patients had uncontrolled hypertension. Among hypertensive patients who are alcoholics, smokers, or salt consumers, the odds of having uncontrolled hypertension are AOR = 16.7, 95% CI = (8.13–34.346); AOR = 7.4, 95% CI = (1.211–45.29); and AOR = 13.4, 95% CI = (7.355–25.098), respectively. Uncontrolled hypertension is 3 (AOR and 95% CI) and 1.5 (AOR and 95% CI) times more prevalent in illiterates and obese people, correspondingly. Hypertensive patients from urban areas, those who did not engage in physical activity, and those who were overweight had uncontrolled hypertension odds that were 0.55, 0.43, and 0.25 (AOR and 95% CI) times lower, respectively. Conclusion. Uncontrolled hypertension is very common among adult hypertensive patients at the hospital. Behavioral practices and lifestyles factors have a strong association with uncontrolled hypertension. Health education and awareness are on the effect of poor behavior practices and lifestyles to increase adherence to hypertension-controlling medical advice.

Prevalence, Cause, and Associated Factors of Visual Impairment Among Diabetic Patients at the Debre Tabor General Hospital, Northwest Ethiopia

Introduction: Visual impairment is a major public health challenge for diabetics who have ocular comorbidities. In Ethiopia, data are lacking on the prevalence of visual impairment among diabetics as well as information on causes and predisposing factors. The current study was designed to assess the causes, risk factors, and levels of diabetes-related visual impairment within an Ethiopian population. Methods: The study enrolled a total of 296 diabetic patients at the Debre Tabor General Hospital (DTGH). Data were ascertained through face-to-face interview, from patients’ medical folder, and through comprehensive ocular health assessment. Descriptive and analytical statistics were performed. Result: Generally, the prevalence of visual impairment among adult diabetic patients was 39.5% (95% confidence interval [CI]: 33.8–45.6). Visual impairment was primarily due to diabetic retinopathy (44.4%), followed by refractive error (20.6%), cataract (13.9%), other ocular conditions (6.1%), and glaucoma (5.4%). Age >45 years (adjusted odds ratio [AOR] = 7.8, 95% CI: 3.5–18), female gender (AOR = 3.0, 95% CI: 1.4–7.7), low educational status (AOR = 8.1, 95% CI: 2.4–26.0), and longer span of diabetes (AOR = 3.7, 95% CI: 2.1–6.8) had a notable association with visual impairment among diabetic patients. Discussion: This study observed a high prevalence of visual impairment in diabetic patients. Diabetic retinopathy, refractive error, and cataract were the most common causes of visual impairment, followed by other ocular conditions and glaucoma. Older age, female gender, low educational status, and longer span of diabetes were important risk factors of visual impairment among diabetic patients. Implications for Practitioners: This result could alert health care professionals to inform their diabetic clients about the serious impacts of diabetes and the need for a regular eye check-up. Health care providers and policy makers should work to integrate the diabetic clinics into a general hospital with an eye care unit for an effective screening of diabetic eye disease and prevention of blindness.

Uncontrolled blood pressure and contributing factors among patients with hypertension at outpatient care of Bedele General Hospital, Southwest Ethiopia: A cross-sectional study

Objective

This study aimed to assess uncontrolled blood pressure and contributing factors among patients with hypertension.

Methods

Hospital-based cross-sectional study was conducted from January to April 2021 at Bedele General Hospital. Data were collected using the semi-structured questionnaire. All patients with hypertension were included using consecutive sampling technique unless ineligible. EpiData 4.4.2 was used for data entry, and SPSS 24.0 was employed for analysis. Binary logistic regression analysis was performed to identify factors associated with uncontrolled blood pressure.

Results

A total of 219 patients with hypertension were included in the study. About 60.3% of participants were male. The mean age of the study participants was 48.54 ± 12.93 years. The prevalence of uncontrolled blood pressure among the study participants was 56.2%. The factors significantly associated with uncontrolled blood pressure were age >60 years (adjusted prevalence ratio = 4.42; 95% confidence interval = (1.71, 11.46); p = 0.002) and the presence of comorbidity (adjusted prevalence ratio = 2.16; 95% confidence interval = (1.22, 3.82); p = 0.008).

Conclusion

More than half of the study participants had uncontrolled blood pressure. Older age and comorbidity were the predictors of uncontrolled blood pressure. Attaining controlled blood pressure is important to avoid consequences of high blood pressure. So, healthcare provider should focus on achieving target blood pressure goal.

Determinants of Hypertension Among Patients with Diabetes mellitus in Public Hospitals of Kembata Tambaro Zone, South Nations Nationalities and Peoples Region, Ethiopia, 2021; A Case Control Study

Introduction

Hypertension is commonly defined as a persistently raised blood pressure in which systolic blood pressure reading (SBP) is greater than or equal to 140 mmHg and diastolic blood pressure (DBP) is greater than or equal to 90 mmHg. The comorbidity of hypertension and diabetes mellitus is complex and is associated with a high risk of complications. However, there are limited studies on determinants of hypertension among patients with diabetes in Ethiopia. Therefore this study aimed to identify the determinants of hypertension among patients with diabetes mellitus in public hospitals of the Kambata Tambaro Zone, Ethiopia.

Methods and Materials

A hospital-based unmatched case-control study was conducted among a total sample of 326 patients with diabetes from June 17, 2021 to August 17, 2021. This study was conducted in five public hospitals. The data were entered into EpiData version 3.1 software and exported to and analyzed using SPSS software version 25.0. Bivariable and multivariable binary logistic regression analyses were used to determine the association between the dependent and independent variables.

Results

Of the 336 study participants, 326 diabetic patients (163 cases and 163 controls) were interviewed resulting in a response rate of 97%. Age group ≥50 years (Adjusted Odds Ratio = 7.00, 95% CI = 1.69–28.9), inactivity in physical exercise (AOR = 5.84, 95% CI = 2.47–13.81), patients who have a history of drinking alcohol (AOR = 2.61, 95% CI = 1.35–5.03) and patients who had poor knowledge on diabetes (AOR = 3.04, 95% CI = 1.69–5.47) were more likely to develop hypertension among diabetic patients.

Conclusion

This study concluded that age, inactivity in physical exercise, history of alcohol intake and poor knowledge were determinants of hypertension among diabetic patients.

Adherence to Self-Care among Patients with Hypertension in Ethiopia: A Systematic Review and Meta-Analysis

Background

Self-care adherence for hypertensive patients is a cornerstone for the control of it and prevention of its complications. However, there are inconsistent findings for self-care adherence of hypertensive patients in Ethiopia. Thus, this systematic review and meta-analysis was done to determine the pooled estimate self-care adherence.

Methods

This systematic review and meta-analysis was reported based on the Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. An intensive search of online databases such as PubMed (MEDLINE), CINHAL, Google Scholar, and advanced Google search was made to access both published and unpublished articles that report self-care adherence among hypertensive patients in Ethiopia. The pooled estimate was done with STATA version 11 metan commands in a 95% confidence interval. The presence of heterogeneity and publication bias were detected by I² and Egger's test, respectively. A random-effect model was obtained, and subgroup analysis was done for the management of heterogeneity.

Result

A total of 24 articles with a total of 7224 participants were included in the final systematic review and meta-analysis. The pooled estimate of overall self-care adherence among hypertensive patients was 36.98% (95% CI: 27.13–46.83). In subgroup analysis, the highest overall self-care adherence was observed in the Amhara region at 53% (95% CI: 46.54, 59.47). The pooled estimate of self-care dimensions such as medication adherence, low-salt diet, physical activity, smoking abstinence, alcohol abstinence, and weight management was 62.71%, 65.96%, 47.28%, 92.53%, 67.59%, and 52.54%, respectively.

Conclusion

The pooled estimate of good self-care adherence among hypertensive patients was low. From the dimensions of self-care, the lowest level was in physical activity and the highest level was in smoking abstinence. Comparing all regions, the lowest level of overall self-care adherence was observed in Addis Ababa, Tigray region, and South Nations and Nationalities of Ethiopia. Screening of adherence to self-care and health education should be provided to every patient during every visit.

Uncontrolled hypertension and associated factors among adult hypertensive patients on follow-up at public hospitals, Eastern Ethiopia: A multicenter study

Objective:

The aim of this study was to assess the magnitude of uncontrolled hypertension and associated factors among adult hypertensive patients on follow-up at public hospitals in Eastern Ethiopia.

Methods:

A hospital-based cross-sectional study was conducted among 415 hypertensive patients in Eastern Ethiopia from June 15 to July 15, 2021. A systematic random sampling technique was used to select the study participants. Data were collected through face-to-face interviews and reviewing patients’ charts. Bivariable and multivariable logistic regression analyses were performed to identify factors associated with uncontrolled hypertension.

Results:

This study revealed that magnitude of uncontrolled hypertension was 48% (95% confidence interval = 43.1%−52.8%). Being male (adjusted odds ratio = 2.05, 95% confidence interval = 1.29–3.26), age ⩾55 years (adjusted odds ratio = 3.16, 95% confidence interval = 1.96–5.08), non-adherence to medication (adjusted odds ratio = 1.83, 95% confidence interval = 1.14–2.94), low diet quality (adjusted odds ratio = 4.04, 95% confidence interval = 2.44–8.44), physically inactive (adjusted odds ratio = 3.20, 95% confidence interval = 1.84–5.56), and having comorbidity (adjusted odds ratio = 3.04, 95% confidence interval = 1.90–4.85) were significantly associated with uncontrolled hypertension.

Conclusions:

In our sample of hypertensive patients on follow-up at public hospitals in Eastern Ethiopia, half had uncontrolled hypertension. Older age, male sex, non-adherence to antihypertensive medication, low diet quality, physically inactive, and having comorbidity were found to be predictors of uncontrolled hypertension. Therefore, sustained health education on self-care practices with special emphasis on older, males, and patients with comorbid conditions.

Antihypertensive prescribing pattern, prescriber adherence to ISH 2020 guidelines, and implication of outpatient drug price on blood pressure control at selected hospitals in Southern Ethiopia

PURPOSE

To determine the impact of drug prescribing pattern, outpatient drug price of medicines, and level of adherence to evidence-based international guidelines on blood pressure (BP) control at selected hospitals in Southern Ethiopia.

METHODS

Hospital-based cross-sectional study was conducted. The data entry and analysis were done by using SPSS version 21.0.

RESULTS

A mean age of participants was 55.87 ± 11.02 years. The rate of BP control was 17.5% based on International Society of Hypertension (ISH) guidelines 2020. In about two-thirds of patients, 270 (66.5%) were taking combination therapy. Mean annual cost of drugs for hypertension was 11.39 ± 3.98 US dollar (USD). Treatment was affordable for only 91 (22.4%) of patients. There was considerable variation on prescriber's adherence to evidence-based guidelines. Body mass index (BMI) of 18-24.9 kg/m², adjusted odds ratio (AOR) = 3.63 (95% confidence interval (C.I), 1.169-11.251, p = 0.026), physically activity, AOR = 12.69 (95% C.I, 1.424-113.17, p = 0.023), presence of no comorbidity, AOR = 12.82 (95% C.I, 4.128-39.816, p = 0.000), and taking affordable antihypertensive regimen, AOR = 3.493 (95% C.I, 1.4242-9.826, p = 0.018), were positively associated BP control.

CONCLUSION

The level of BP control, affordability of drugs for the management of hypertension and related comorbidities, and the prescriber's adherence to evidence-based guidelines were inadequate. Therefore, addressing factors associated with good BP control including affordability and clinician adherence to evidence-based guidelines by responsible stakeholders could improve BP control and reduce associated complications.

A prospective longitudinal study with treated hypertensive patients in Northern Bangladesh (PREDIcT-HTN) to understand uncontrolled hypertension and adverse clinical events: A protocol for 5-years follow-up

Introduction

Uncontrolled hypertension is the most common cause of major adverse clinical events (MACE), such as myocardial infarction, strokes, and death due to CVDs, in both developed and developing countries. Western-led studies found that treated hypertensive adults with uncontrolled hypertension were more at-risk of all-cause and CVD-specific mortality than normotensives. The PRospEctive longituDInal sTudy of Treated HyperTensive patients of Northern-Bangladesh (PREDIcT-HTN) study principally aims to estimate the incidence of MACE in treated hypertensive patients and identify the determinants of MACE. The secondary objective is to find the prevalence of uncontrolled hypertension in treated hypertensive patients and the associated risk factors.

Methods and analysis

The treated hypertensive patients were obtained from the Hypertension and Research Center (H&RC), Rangpur, Bangladesh, from January to December 2020. Based on the eligibility criteria, 2643 patients were included to constitute the PREDIcT-HTN cohort. Baseline data was retrieved from the H&RC registry, and five follow-up waves are planned yearly (2021–2025). A questionnaire will be administered at each follow-up visit on hypertension control status, behavioral factors, quality of life, dietary adherence, and high blood pressure compliance-related variables. The participant will be right censored if the patient develops MACE, death due to any cause, loss to follow-up, or at the end of the study. A proportional hazard model will identify the risk factors of MACE. Multinomial logistic regression analyses will be performed to determine the predictors of the hypertension control status by medication and dietary adherence after adjusting confounders.

Ethics and dissemination

The ethical approval for this study was obtained from the Institutional Review Board, North South University [Ref: 2019/OR-NSU/IRB-No.0902]. The participants will provide written consent to participate. The findings will be disseminated through manuscripts in clinical/academic journals and presentations at professional conferences and stakeholder communication.

Blood Pressure and Blood Glucose Control and Associated Factors Among Adults with Hypertension at Three Public Hospitals in Southern Ethiopia

INTRODUCTION

There is inadequate information on blood pressure (BP) and FBG (Blood pressure and Fasting blood glucose) control among adult hypertensive patients in Southern Ethiopia.

AIM

To determine the level and factors associated with poor BP and FBG control among adult hypertensive patients on regular follow-up at three public hospitals RESULTS: We included 406 adult hypertensives with mean age of 55.87 ± 11.03 years. Mean systolic BP was 134.46 ± 13.44 mmHg; and mean diastolic BP was 82.10 ± 9.44 mmHg. More than eight out of 205 (86.2%) of patients did not achieve BP and FBG target level. Having body mass index 18-24.9 kg/m², Adjusted odds ratio (AOR) = 0.317 (95% C.I. for AOR, 0.135-0.740, p = 0.008); having no comorbidity, AOR = 0.425 (95% C.I. for AOR, 0.232-0.779, p = 0.006); physically activity, AOR = 0.303 (95% C.I., 0.110-0.829, p = 0.020); having low perceived health risk, AOR = 0.095 (95% C.I., 0.014-0.632, p = 0.015); taking monotherapy, AOR = 3.34 (95% C.I. for AOR, 1.121-10.524, p = 0.033); and history of hospitalization, AOR = 7.048 (95% C.I. for AOR, 2.486-19.954, p = 0.000) were associated with poor BP and FBG control.

CONCLUSIONS

The level of BP and FBG control was low. Improving screening of hypertensive patients for diabetes; addressing obesity and mental health; strengthening healthy life style interventions and enhancing appropriate dose intensification of prescribed anti-hypertensives by responsible bodies are critical to improve BP and FBG control.

Prevalence of diabetic retinopathy among diabetic patients in Northwest Ethiopia-A cross sectional hospital based study

BACKGROUND

Diabetic retinopathy is the most common microvascular complication of diabetes mellitus on eye and it is the leading cause of visual impairment among productive segment of the population. Globally, the prevalence of diabetic retinopathy is reported to be 27%. In Ethiopia, sufficient data is lacking on the prevalence of diabetic retinopathy as well as information on its predisposing factors. The study was required to assess the prevalence of diabetic retinopathy and its predisposing factors in diabetic patients attending at a General Hospital in Ethiopia.

METHODS

An institution based cross sectional study was employed on 331 diabetic patients recruited with a systematic random sampling technique. Data were collected through structured questionnaire, tracing patients' medical folder and ocular health examination. Data were analyzed with Statistical Package for Social Science Version 20. Logistic regression methods of analysis were used to figure out predisposing factors of diabetic retinopathy. Adjusted odds ratio with 95% confidence interval was used to determine the strength of association.

RESULT

A total of 331 diabetic patients completed the study with a response rate of 99.10%. The median duration of diabetes was 5 years. The prevalence of diabetic retinopathy was 34.1% (95%Confidence Interval (CI): 28.7%-39.3%). Low family monthly income (Adjusted Odds Ratio (AOR) = 7.43, 95% CI: 2.44-22.57), longer duration of diabetes (AOR = 1.44, 95% CI: 1.30-1.58), poor glycemic control (AOR = 4.76, 95%CI: 2.26-10.00), and being on insulin treatment alone (AOR = 3.85, 95%CI: 1.16-12.74) were independently associated with diabetic retinopathy.

CONCLUSION AND RECOMMENDATION

The prevalence of diabetic retinopathy was 34.1%, higher than national and global figures. Low family monthly income, longer duration of diabetes, poor glucose control and being on insulin treatment alone were important risk factors of diabetic retinopathy. Proper diabetes self management and early screening of diabetic retinopathy in all diabetic patients were recommended.

Development and Psychometric Validation of the Hypertension Beliefs Assessment Tool Among Adult Population in Northwest Ethiopia

BACKGROUND

In Ethiopia, the majority of hypertension cases remain undiagnosed, untreated, and uncontrolled. Beliefs about hypertension and its complications play an important role in hypertension management behaviors. Accurate assessment of individuals' beliefs towards the disease is of paramount importance in the design of hypertension education. This study aimed to develop and validate a hypertension belief assessment tool based on the Health Belief Model for the general population among rural adults in northwest Ethiopia.

METHODS

The study included item construction, face and content validation, factor analysis, and establishment of reliability and validity of the tool. A total of 308 rural adults participated in the study. Inter-item and item-to-total correlations were used to examine the items assessed with the same content on a scale. Principal component analysis with promax rotation was used to extract the factors. Internal consistency reliability was assessed using Cronbach's alpha coefficient. Convergent and discriminant validity were assessed using average variance extraction and maximum shared variance.

RESULTS

The median age of the participants was 41 (IQR: 31-55) years. Of the participants, 175 (56.8%) were female and 287 (93.2%) were farmers. Kaiser-Meyer-Olkin test value of 0.84 and significant Bartlett's test of sphericity (p=0.000) revealed that the data were suitable for exploratory factor analysis. The principal component analysis identified 6 factors, which explained 70.06% of the variation of the hypertension belief. Cronbach's alpha was 0.85 for the entire scale, ranging from 0.74 to 0.92 for the sub-domains. The average variance extracted was above 0.5 for all factors, indicating convergent validity. The maximum shared variance between the two constructs was lower than the average variance extracted from each factor, indicating that discriminating validity had been established.

CONCLUSION

The hypertension belief assessment tool was found to be valid and reliable, which can be used to measure the health beliefs on hypertension for the rural adult population.

Heavy khat (Catha edulis) chewing and dyslipidemia as modifiable hypertensive risk factors among patients in Southwest, Ethiopia: Unmatched case-control study

BACKGROUND

The burden of hypertension is more devastating in low-and middle-income countries, including sub-Saharan Africa than in high-income countries. Among the modifiable risk factors, dyslipidemia and khat chewing were expanding at an alarming rate in Ethiopia but were still underestimated. Thus, this study aimed to assess heavy khat (Catha edulis) chewing and dyslipidemia as modifiable hypertensive risk factors among patients in the southwest, Ethiopia.

METHODS

A facility-based case-control study was conducted among 136 cases and 270 controls from May 15 to July 30, 2017. A consecutive sampling technique was used in this study. Epi data version 3.1.1 and SPSS version 21 were used for data entry and analysis. Descriptive statistics and bivariate and multivariate logistic regression analyses were performed. Both crude and adjusted odds ratios and 95% confidence intervals were reported.

RESULTS

The majority of the cases had a total cholesterol to high-density lipoprotein ratio of >5 (72.1%). The odds of hypertension increased among participants who had attended no formal education [AOR = 2.25, 95% CI: (1.05-4.82)], history of alcohol consumption [AOR = 5.93,95% CI:(3.11-11.30)], moderate khat chewing [AOR = 3.68, 95% CI:(1.69,8.01)], heavy khat chewing [AOR = 18.18, 95% CI: (3.56-92.89)], mild intensity physical activity [AOR = 3.01, 95% CI: (1.66-5.47)], type of oil used for food preparation [AOR = 2.81, 95% CI: (1.49-5.28)], and dyslipidemia [AOR = 6.68, 95% CI: (2.93-15.23)].

CONCLUSION

The study showed that modifiable risk factors were the major factors associated with the development of hypertension. The findings of this study highlighted that health education is needed to focus on physical exercise, quitting excess alcohol consumption, quitting khat chewing by giving special emphasis to those who had no formal education. In addition, consideration should be given to a healthy diet free of cholesterol and unhealthy behavior.

Rate of blood pressure control and its determinants among adult hypertensive patients at Jimma University Medical Center, Ethiopia: Prospective cohort study

Introduction

Despite the fact that the goals for the management of hypertension are well-defined and effective therapies are available, control of hypertension remains poor in countries with low resources including Ethiopia. This study aimed to determine blood pressure control rate and its determinants among ambulatory adult hypertensive patients at Jimma University Medical Center.

Methods

A general prospective cohort study was conducted among adult hypertensive patients who had regular follow-up at Jimma University Cardiac Clinic from 20 March to 20 June 2018. Hypertensive patients who fulfilled the inclusion criteria were selected in the first month of the data collection period. Then, only those patients who visited the clinic at the first month were consequently followed-up for the next 3 months. The Eighth Joint National Committee guideline was used to categorize controlled and uncontrolled blood pressures. Patients' specific data were collected using a structured data collection tool. Data were analyzed using the statistical software package SPSS version 21.0. Bivariate and multivariable logistic regression analysis was used to identify independent variables influencing blood pressure control. p-values of less than 0.05 were considered statistically significant.

Results

From a total of 416 patients, 237 (57.0%) were male with a mean age of 56.50 ± 11.96 years. Two hundred and fifty eight (62.0%) participants had comorbid conditions and 275 (66.1%) were on combination therapy. The rate of blood pressure control was 42.8%. Age ⩾60 years was negatively associated with uncontrolled blood pressure (adjusted odd ratio = 0.52, confidence interval = 0.31-0.88, p = 0.015). Medication non-adherence (adjusted odd ratio = 1.64, confidence interval = 1.04-2.58, p = 0.034) and non-adherence to international guidelines (adjusted odd ratio = 2.33, confidence interval = 1.49-3.64, p < 0001) were positively associated with uncontrolled blood pressure.

Conclusion

The rate of blood pressure control among hypertensive patients was suboptimal. Age, clinicians' non-adherence to international guidelines, and patients' non-adherence to medications were independent predictors of blood pressure control. Physicians and clinical pharmacists should adhere to guidelines for better treatment and care of hypertensive patients.

Self-care practice among hypertensive patients in Ethiopia: systematic review and meta-analysis

BACKGROUND

In high-income and low-income countries, including Ethiopia, hypertension (HTN) is a serious public health concern. As a consequence, a massive self-care practice (SCP) is necessary, and the domains of SCP, including adherence to medication, physical activity, weight management, low-salt diet, non-smoking, moderate alcohol usage, and dietary management, are required. However, there is no nationwide study on HTN SCPs in Ethiopia. This meta-analysis, therefore, aimed to estimate the pooled level of HCP among individuals living with HTN in Ethiopia.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guideline was used to report this systematic review and meta-analysis. We systematically searched the databases PubMed/MEDLINE, Embase, Google Scholar and Science Direct for studies conducted in Ethiopia. All observational studies published until July 2020 were included. Data were analysed using R V.3.5.3 software, and the pooled prevalence with 95% CIs was presented using tables and forest plots. The presence of statistical heterogeneity (I ²) within the included studies was evaluated. We used a funnel plot to identify evidence of publication bias. The random-effects meta-analysis model was employed to estimate the pooled proportion of good HTN SCPs.This was submitted for registration with the International Prospective Register of Systematic Reviews in March 2020 and accepted with the registration number CRD42020175743 (https://www.crd.york.ac.uk/PROSPERO).

RESULTS

Our search databases produced 356 papers. Twelve of these papers fulfilled the inclusion and were found suitable for the review. The total population in this study was 3938. Off these hypertensive populations, 44% (95% CI 34 to 53) had good SCP. The subgroup analysis for each component of SCP was done. The subgroup analysis of good adherence to low-salt diet, alcohol abstinence, medication adherence, non-smoking, physical exercise and weight management was 52% (95% CI 39% to 66%), 77% (95% CI 69% to 88%), 65% (95% CI 45% to 85%), 92% (95% CI 88% to 95%), 43% (95% CI 30% to 56%) and 51% (95% CI 32% to 69%), respectively. In conclusion, nearly half of patients with HTN had good SCPs.

The Role of Health Care Quality in Hypertension Self-Management: A Qualitative Study of the Experience of Patients in a Public Hospital, North-West Ethiopia

Purpose

Hypertension is becoming a global epidemic in all population groups. For its effective management and control, patients should have enhanced self-management skills and get adequate support from care providers. Although the quality of health care is critical in enhancing self-management behaviors of patients with hypertension, the issue has not been fully explored in the Ethiopian context. Therefore, the purpose of this study was to explore the experience of hypertensive patients on the quality of health care and the self-management practice in a public hospital in North-west Ethiopia.

Patients and Methods

This qualitative study involves a phenomenological approach. Participants were hypertension patients who are on treatment follow-up. They were recruited purposively with maximum variation approach. Eleven in-depth interviews and two key informant interviews were undertaken using a semi-structured interview guide with hypertensive patients and nurses respectively. Interviews were audio recorded, transcribed verbatim, translated into English, and then analyzed thematically by the investigators.

Results

The analysis identified two main themes and seven sub-themes. The first theme “experience in self-management practice” describes medication adherence, lifestyle modification, and self-monitoring of blood pressure. The second theme “experience in the quality of health care” discusses access to health services, patient-centered care, behavior of health care providers, and time and patient flow management.

Conclusion

The self-management practice of hypertensive patients is sub-optimal. Although several individual patient issues were identified, facility-level problems are mainly responsible for poor self-management practice. The main facility-level barriers, as reported by participants, include shortage of medicines, high cost of medicines, busyness of doctors due to high patient load, lack of appropriate education and counseling services, poor patient-provider interaction, and long waiting times. Intervention areas should focus on providing appropriate training for health care providers to enhance the patient–provider relationship. Improving the supply of hypertensive medications is also paramount for better medication adherence.

Blood Pressure Control with Reference to Intensive Blood Pressure Targets Among Hypertension Patients on Chronic Follow-Up at Dessie Referral Hospital, Northeast Ethiopia

Background

Hypertension is a risk factor for heart, brain, kidney, and other diseases. It is also the major cause of premature death. Thus, it is important to prevent, treat, and control hypertension and to reduce the risk of cardiovascular disease.

Objective

To determine the level of blood pressure control and associated factors based on the new intensive blood pressure goals (<130/80 mmHg).

Methods

A cross-sectional study design was used to assess the level of blood pressure control and associated factors from February 15 to April 15, 2019. Two hundred and sixteen patients were selected through a systematic sampling technique.

Results

From 203 hypertension patients incorporated in the study, 102 (50.2%) were females. The mean age of patients documented during the last date of follow-up was 55.2 (SD=±14.47). About 51.2% of patients were less than 5 years from the day of diagnosis of hypertension. The majority of the study participants (111, 54.7%) were using two antihypertensives. The most common anti-hypertensive medication was hydrochlorothiazide (HCT), at 25 (12.3%). The most common combination drug therapy used was the combination of HCT and calcium channel blockers, at 62 (30.5%). Heart failure (22, 20.8%), stroke (18, 16.98%), and dyslipidemia (17, 16.04%) were the top three comorbidities. Based on the new intensive targets of blood pressure control (<130/80 mmHg), the blood pressure was controlled for only 25 (12%) patients.

Conclusion

The level of blood pressure control for hypertensive patients on chronic follow-up at Dessie Referral Hospital was very poor.

Sight-threatening Diabetic Retinopathy and Associated Risk Factors Among Adult Diabetes Patients at Debre Tabor General Hospital, Northwest Ethiopia

BACKGROUND

People with diabetes have an increased risk of developing sight-threatening conditions. Sight threatening diabetic retinopathy (STDR) is an advanced microvascular of complication of diabetes on the eye. It remains one of the leading causes of preventable blindness among working age adults around the world. There is a paucity of evidence on the prevalence of STDR and its associated factors in Ethiopia, particularly in the study area. Therefore, the aim of our study was to determine the prevalence of STDR and its associated factors among adult diabetes patients at Debre Tabor General Hospital (DTGH), Northwest Ethiopia.

MATERIALS AND METHODS

An institution-based cross-sectional study was conducted on 306 diabetes patients at Debre Tabor General Hospital with systematic random sampling technique. Semi-structured questionnaire, document review and physical examination were applied to collect the data. Binary and multivariable logistic regression model were used to identify associated factors for STDR.

RESULTS

The majority of the participants 163 (53.3%) were type 1 diabetes (T1DM) and the mean age of T1 and T2 DM participants was 34.5 (12.8) and 58.7 (10.7) years respectively. The prevalence of STDR was 15.3% (95%CI: 9.6%-20.9%) and 11.9% (6.6-17.5) in T1DM and T2DM, respectively. Low family monthly income (adjusted odds ratio (AOR)=4.4, 95%CI: 1.05-18.40) among T2DM, longer duration of diabetes (AOR=10.9, 95%CI: 2.94-40.4) among T1DM (AOR=3.54, 95CI: 1.06-11.8) among T2DM and poor glycemic control (AOR=3.93, 95%CI: 1.06-14.5) and hypertension (AOR=5.86, 95%CI: 1.20-28.6) among T1DM and BMI (AOR=4.79, 95%CI: 1.35-17.00) among T2DM were significantly associated with STDR.

CONCLUSION AND RECOMMENDATION

The prevalence of STDR was high. Low family monthly income, longer duration of diabetes, poor glycemic control, hypertension and obesity were positively associated with STDR. Early screening of STDR and improving diabetes self management in all diabetes patients were recommended.

Medication Adherence and Its Association With Quality of Life Among Hypertensive Patients Attending Primary Health Care Centers in Saudi Arabia

Background Chronic diseases require long-term medication and adherence to medication is important for the control of disease as well as prevention of complications. Non-compliance may lead to worsening of the disease, which may affect patients' quality of life. This study aimed to assess the level of medication adherence and its association with quality of life (QOL) among hypertensive patients in Buraidah, Saudi Arabia. Methods A cross-sectional study was carried out in which 299 hypertensive patients were recruited from the randomly selected primary health care centers. Medication adherence was assessed by Hill-Bone Medication Adherence Scale, and quality of life was assessed by the World Health Organization's Quality of Life (WHOQOL)-BREF. Multivariate linear regression was used to assess the association of medication adherence with quality of life. Data was analyzed using SPSS version 21.0 (IBM Inc., Armonk, USA). Results The prevalence of poor adherence was found to be 38.8%. We did not find a significant association of medication adherence with any of the four (physical, psychological, social relationship, and environmental) domains of WHOQOL-BREF. However, poor medication adherence was associated with poor perceived overall QOL adjusted β=-0.012 (95% confidence interval [CI]: -0.021 to -0.002; p=0.018) and health adjusted β=-0.013 (95% CI: -0.025 to -0.002; p<0.018). Conclusion We found a high prevalence of non-adherence among hypertensive patients. This calls for developing interventions to improve compliance with medications to prevent complications of hypertension. Our study could not find a significant association of medication adherence with any of the domains of QOL, while poor adherence was associated with lower overall perceived QOL and health. Nonetheless, worsening of disease due to non-adherence may affect the QOL of patients. We recommend large scale prospective studies to explore the relationship between medication adherence and QOL.

Level of Physical Activity and Its Associated Factors Among Type II Diabetes Patients in Dessie Referral Hospital, Northeast Ethiopia

BACKGROUND

Overweight and obesity results in poor control of chronic illnesses such as diabetes mellitus. The main reason for being overweight and obese among patients with chronic illness is low level of physical activity. Thus, this study aimed to assess level of physical activity and its associated factors among type II diabetes patients at Dessie Referral Hospital, Northeast Ethiopia.

METHODS

A hospital-based cross-sectional study was employed from October 1 to November 25 2019 in Dessie Referral Hospital. The study utilized systematic sampling technique to recruit the sample population of 364 diabetic patients. Face-to-face exit interview was used to collect the data. The data were presented with text and tables. Bivariable and multivariable binary logistic regression was employed to identify independent predictors of low level of physical activity at a P-value of <0.05.

RESULTS

From the total study participants, 110 (33.1%) of them did not perform health enhancing physical activity. Patients whose body mass index was below 18.5 kg/m2 did not perform health enhancing physical activity twice more likely compared with patients whose weight was normal (AOR=2.36, 95%CI: 0.02-5.42). Patients who were depressed did not perform health enhancing physical activity five times more likely compared with their counterparts (AOR=4.83, 95%CI: 1.46-15.96). In addition, being widowed (P=0.037), living in an urban area (P=0.028) and duration of disease (P=0.020) were statistically associated with low level of physical activity.

CONCLUSION AND RECOMMENDATIONS

The level of physical activity among patients with type II diabetes was low. Being widowed, living in an urban area, being underweight, duration of disease and being depressed were independent predictors of low level of physical activity. Health education should be given in every visit to patients with type II diabetes. Promotion of physical activity through campaign should be done.

Characterizing Patients with Uncontrolled Blood Pressure at an Urban Hospital in Hanoi, Vietnam

Great efforts to advance the diagnosis and treatment of hypertension for controlling hypertension have been made; however, the rates of uncontrolled blood pressure are still high. This study explored the rate of uncontrolled hypertension in patients with hypertension managed in an urban hospital of Vietnam and identified associated factors. A cross-sectional survey was performed from August to October 2019 among hypertensive patients at an urban hospital in Hanoi, Vietnam. Blood pressure was evaluated at the time of medical examination. Demographic, clinical, and behavioral characteristics were also collected. Multivariate logistic regression was used to identify the factors related to uncontrolled hypertension. Among 220 patients, the rate of uncontrolled hypertension was 40.5%. Females had a lower likelihood of having uncontrolled hypertension compared to males (adjusted OR = 0.33; 95% CI = 0.11–0.98). Higher duration of diseases (adjusted OR = 1.07; 95% CI = 1.01–1.14) and higher body mass index (adjusted OR = 1.23; 95% CI = 1.05–1.45) were positively associated with uncontrolled hypertension. Patients who carried supplies needed for self-care, cut down on stress, exercised regularly, and stopped/cut down on smoking were also less likely to develop uncontrolled hypertension. This study reveals that uncontrolled hypertension was common among hypertensive patients in Vietnam. Improving self-care capacity and encouraging healthy behaviors are critically important to control blood pressure, particularly among patients who were males and had high disease duration and body mass index.

Prevalence and factors associated with uncontrolled hypertension among adult hypertensive patients on follow-up at Northern Ethiopia, 2019: cross-sectional study

Introduction

uncontrolled hypertension is a major risk factor for cardiovascular, renal, and cerebrovascular morbidities and mortalities. This study aims to assess the prevalence and factors associated with uncontrolled hypertension among adult hypertensive patients.

Methods:

hospital-based cross-sectional study was conducted. Systematic random sampling technique was used to select 396 hypertensive patients. Respondents were interviewed and their medical charts were reviewed using pretested structured questionnaire. Bivariable logistic regression was employed to examine the crude associations between the outcome variable and determinant variables. This was followed by multivariable logistic regression analysis using those variables with P-value ≤ 0.25 in the bivariable analysis.

Results

of the total 396 hypertensive patients the prevalence of uncontrolled hypertension was found to be 48.6%. One fourth (26.1%), 231(59.1%), 289(73.9%), and 151(38.6%) hypertensive respondents were non adherent to anti-hypertensive medication, physical exercise, low salt diet, and weight management respectively. Age ≥50 years old (AOR = 2.33, 95%CI: 1.25, 4.35), non-adherence to anti-hypertensive medication, (AOR = 1.82 95%CI: 1.08, 3.04), non-adherence to physical exercise (AOR = 1.79 95%CI: 1.13, 2.83), non-adherence to low-salt diet (AOR = 1.98 95%CI: 1.18,3.31), and non-adherence to weight management (AOR = 2.06, 95%CI: 1.31, 3.23) were significantly associated with uncontrolled hypertension.

Conclusion

the prevalence of uncontrolled hypertension was high. Older hypertensive patients, non-adherent to their medications, physical inactivity, non-adherent to low salt diet and non-adherent to weight management were more likely to have uncontrolled hypertension. Therefore, more effort should be dedicated to those identified modifiable risk factors to maximize blood pressure control.

Managing Cardiovascular Risk Factors without Medications: What is the Evidence?

In this era of potent medications and interventional cardiovascular (CV) procedures, the importance of beginning with and including Therapeutic Lifestyle Changes (TLC) is frequently forgotten. A major goal of this review article is to show and emphasize that modification of CV risk with nonmedication approaches makes an essential contribution to CV risk reduction. Available information on TLC and modifiable CV risk factors was reviewed and assessed. Modifiable major CV risk factors include diabetes mellitus, hypertension, hyperlipidemia, tobacco abuse, obesity, stress, and a sedentary lifestyle. Age as a major CV risk factor is, of course, not susceptible to modification. A contribution to the control of CV risk factors can occur without the start of medications and there is proof of benefit for beginning with a non-pharmacological approach. TLC can benefit all of the major modifiable CV risk factors and there is good evidence for the additional benefit of supervised and group TLC. TLC includes physical activity, diet, and smoking cessation. Evidence for the benefits of TLC in reducing CV disease events is well established. However, medications must be added in those patients with higher CV risk to obtain maximum cholesterol reduction (lower is better for the low-density lipoprotein cholesterol) and good blood pressure control. The benefit of TLC is frequently forgotten in this era of potent medications and invasive procedures. The benefits of diet and physical activity are emphasized with supporting data. Many motivated patients can prolong their lives significantly by dedication to TLC. Therapeutic Lifestyle Change (TLC) especially encompasses increased physical activity, a healthy diet, and smoking cessation. There is extensive proof for the benefit of TLC in contributing to cardiovascular (CV) disease prevention. CV diseases have strong metabolic and inflammatory components, both of which can be improved by TLC.

Treatment resistant hypertension among ambulatory hypertensive patients: A cross sectional study

BACKGROUND

Treatment resistant hypertension(TRH) is detrimental risk of cardiovascular and premature deaths. Globally, the prevalence of resistant hypertension is inclining from time to time and it is yet to be determined in Ethiopia.

OBJECTIVE

To assess the prevalence of apparent TRH and its predictors among ambulatory hypertensive patients on follow up in hypertension clinic of Mekelle Hospital, Northern Ethiopia.

METHOD

A hospital based cross sectional study was conducted from Nov 25, 2018 to July 20, 2019, among 338 adult ambulatory hypertensive patients on follow up in Mekelle Hospital hypertension clinic. Hypertensive patient aged ≥18 years who were on regular follow up and taking antihypertensive medications for at least 6 months were included in the study. A simple random sampling technique was used to recruit the study patients.

RESULTS

A total of 338 adult ambulatory hypertensive patients were analysed. More than half, 182 (53.8%) patients were females and the average age of the patients was 58.9 ±11.5. Three hundred thirty-three (98.5%) patients had no family history of hypertension. Majority, 66.8% of the patients were on monotherapy. The prevalence of apparent TRH was calculated to be 8.6% [Confidence Interval = 0.056-0.116]. Patients with Body Mass Index(BMI) greater than 30[Adjusted Odds Ratio(AOR) = 12.1, 95%CI:2.00-73.19, p = 0.007] and longer duration of hypertension were the predictors of resistant hypertension.

CONCLUSION

Even if escalation of antihypertensive medications was not aggressive, apparent TRH was common in the study setting. Obesity (BMI greater than 30) and longer duration of hypertension since diagnosis were the predictors of TRH. Meticulous emphasis should be placed on to detect the prevalence of true hypertension resistance and future studies should discover the impact of aggressive antihypertensive medications scale up on the risks of TRH.

Uncontrolled hypertension in Ethiopia: a systematic review and meta-analysis of institution-based observational studies

Background

Uncontrolled hypertension is one of the major risk factors of cardiovascular and cerebrovascular diseases. The prevalence of hypertension in Ethiopia is expected to reach up to 30%. The aim of this study was to determine the prevalence of uncontrolled hypertension among hypertensive patients on treatment in Ethiopia.

Methods

Electronic databases and search engines including EMBASE (Ovid), PubMed/Medline, and Google Scholar were searched for original records in the English language addressing hypertension control in Ethiopia from 2000 to 2018. Data were extracted using a format prepared in Microsoft Excel and exported to STATA 15.0 software for analyses. The study protocol is registered at PROSPERO with reference number ID: CRD42018116336.

Results

A total of 13 studies with 5226 hypertension patients were included for systematic review and meta-analysis. The pooled prevalence of uncontrolled hypertension in Ethiopia was 48% (95% confidence interval (CI): 36, 61%). The result of the sub-group analysis, based on the year of publications, revealed that the prevalence of uncontrolled BP was highest in 2016 (63%; CI: 60, 67%) and in 2015 (59%; CI: 53, 65%). Univariate meta-regression revealed that sampling distribution was not a source of heterogeneity for the pooled estimate as well as the sub group analysis.

Conclusion

The prevalence of uncontrolled hypertension was high in Ethiopia. This alarming public health issue fuels the ever-increasing cardiovascular and cerebrovascular diseases. The ministry of health has to design a policy and implementation mechanisms to reduce uncontrolled hypertension prevalence and improve awareness on blood pressure control.

Practice and predictors of self-care behaviors among ambulatory patients with hypertension in Ethiopia

BACKGROUND

Despite the benefits of evidence-based self-care behaviors in the management of hypertension, hypertensive patients have low rate of adherence to the recommended self-care behaviors. Studies related to self-care behaviors among hypertensive patients are limited in Ethiopia.

OBJECTIVE

To assess the rate of adherence to self-care behaviors and associated factors among hypertensive patients.

METHOD

A cross-sectional study was conducted at the cardiac clinic of Ayder comprehensive specialized hospital among ambulatory hypertensive patients. Self-care behaviors were assessed using an adopted Hypertension Self-Care Activity Level Effects (H-SCALE). Data were collected through patient interview and review of medical records. Binary logistic regression analysis was performed to identify predictors of self-care behaviors.

RESULT

A total of 276 patients were included in the study. The majority of the participants were nonsmokers (89.9%) and alcohol abstainers (68.8%). Less than half of the participants were adherent to the prescribed antihypertensive medications (48.2%) and recommended physical activity level (44.9%). Moreover, only 21.45% and 29% were adherent to weight management and low salt diet recommendations, respectively. Our finding indicated that rural resident (adjusted odds ratio [AOR]: 0.45, 95% confidence interval [CI]: 0.21-0.97), comorbidity (AOR: 0.16, 95% CI: 0.08-0.31), and negative medication belief (AOR: 0.25, 95% CI: 0.14-0.46) were significantly associated with medication adherence. Female sex (AOR: 0.46, 95% CI: 0.23-0.92), old age (AOR: 0.19, 95% CI: 0.06-0.60) and lack of knowledge on self-care behaviors (AOR: 0.13, 95% CI: 0.03-0.57) were significantly associated with adherence to weight management. Female sex (AOR: 1.97, 95% CI: 1.03-3.75) and lack of knowledge on self-care (AOR: 0.07, 95% CI: 0.03-0.16) were significantly associated with adherence to alcohol abstinence. Female sex (AOR: 6.33, 95% CI: 1.80-22.31) and khat chewing (AOR: 0.08, 95% CI: 0.03-0.24) were significantly associated with non-smoking behavior. There was also a significant association between female sex and physical activity (AOR: 0.22, 95% CI: 0.12-0.40).

CONCLUSION

The rate of adherence to self-care behaviors particularly weight management, low salt intake, physical exercise, and medication intake was low in our study. Elders, females, khat chewers, rural residents, and patients with negative medication belief, comorbidity, and inadequate knowledge of SCBs were less adherent to self-care behaviors compared to their counterparts. Therefore, health care providers should pay more emphasis to patients at risk of having low self-care behaviors.

Plasma Renin Activity Is a Predictive Biomarker of Blood Pressure Response in European but not in African Americans With Uncomplicated Hypertension

BACKGROUND

Interindividual variability in blood pressure (BP) response to antihypertensives has been reported. Although plasma renin activity (PRA) is a potential biomarker for personalizing antihypertensive therapy in European American (EA) and African American (AA) hypertensives, clinical utility of PRA-guided prescribing is incompletely understood.

METHODS

Using systematic-phased approach, PRA's clinical utility was assessed. After categorizing by baseline PRA, clinic systolic BP (SBP) responses to metoprolol and chlorthalidone were compared in 134 EAs and 102 AAs enrolled in the Pharmacogenomics Evaluation of Antihypertensive Responses-2 (PEAR-2) trial. Receiver operating characteristic (ROC) analysis was conducted in EAs. Data from PEAR-2 AAs were used to estimate an optimal PRA cut point using multivariable linear regression models. The derived cut point in AAs was tested in a meta-analysis of 2 independent AA cohorts, and its sensitivity and specificity were assessed.

RESULTS

EAs with PRA < 0.65 ng/ml/hour had a greater decrease in SBP to chlorthalidone than metoprolol (by -15.9 mm Hg, adjusted P < 0.0001), whereas those with PRA ≥ 0.65 ng/ml/hour had a greater decrease in SBP to metoprolol than chlorthalidone (by 3.3 mm Hg, adjusted P = 0.04). Area under ROC curve (0.69, P = 0.0001) showed that PRA can predict SBP response among EAs. However, we observed no association between PRA and SBP response in PEAR-2 AAs. Among independent AA cohorts, those with PRA ≥ 1.3 ng/ml/hour (PEAR-2-derived cut point) responded better to atenolol/candesartan than hydrochlorothiazide (meta-analysis P = 0.01). However, sensitivity of the derived cut point was 10%.

CONCLUSIONS

PRA at the previously established 0.60-0.65 ng/ml/hour cut point is an effective predictive biomarker of BP response in EAs. However, we were unable to identify PRA cut point that could be used to guide antihypertensive selection in AAs.

Uncontrolled hypertension and associated factors among adult hypertensive patients in Ayder comprehensive specialized hospital, Tigray, Ethiopia, 2018

Background

Despite the availability and improvement in diagnostic and therapeutic interventions with proven benefits in reducing cardiovascular morbidity and mortality, control rates of hypertension remain poor and grossly inadequate. Around one billion individuals are living with uncontrolled hypertension globally. Uncontrolled hypertension among hypertensive patients on treatment in Ethiopia ranges from 11.4 to 69.9%. Therefore, the aim of this study was to determine the magnitude and associated factors of uncontrolled hypertension among hypertensive patients in Ayder comprehensive specialized hospital, Tigray, Ethiopia 2018.

Methods and materials

Hospital-based cross-sectional study design was conducted from February 16–April 30/2018. Simple random sampling method was used to select 320 participants. Data was collected using interviewer administered standard structured questionnaire. Self-care practice measuring tool was adopted from hypertension self-care activity level effects (H-scale). Data was entered to and cleaned by Epi Info version 7 and it was exported to SPSS version 22 for analysis. Binary logistic regression model (AOR, 95% CI and p-value < 0.05) was used to determine the predictors of uncontrolled hypertension.

Result

From the total respondents, 164 (51.2%) were females. The mean age of the respondents was 53.83 + 14.52 years. Prevalence of uncontrolled hypertension was found 52.5%. Overweight (AOR = 4.527, 95% CI: 2.247–9.123), co-morbidity (AOR = 2.112, 95% CI: 1.218–3.662), non-adherence to anti-hypertensive medication (AOR = 2.062, 95% CI: 1.030–4.129), non-adherence to physical activity (AOR = 1.931, 95% CI: 1.074–3.470) and non-adherence to alcohol abstinence (AOR = 2.093, 95% CI: 1.109–3.948) are independent predictors of uncontrolled hypertension.

Conclusion

the prevalence of uncontrolled hypertension is high. Patients’ adherence to antihypertensive medication, physical exercise and alcohol abstinence should be maximized. Weight reduction and early identification and management of co-morbidities are also crucial.
