Inequalities in undiagnosed hypertension among adult Nepalese population: Evidence from a nationally representative survey

Relationship between psychological distress, health behaviours and future reports of hypertension among adults in East Zimbabwe: a cohort study

INTRODUCTION

Extensive cross-sectional evidence has demonstrated an association between psychological distress (PD) and hypertension. However, evidence on the temporal relationship is limited, especially in low-income and middle-income countries. The role of health risk behaviours including smoking and alcohol consumption in this relationship is also largely unknown. The aim of this study was to investigate the association between PD and later development of hypertension, and how this association may have been influenced by health risk behaviours, among adults in east Zimbabwe.

METHODS

The analysis included 742 adults (aged 15-54 years) recruited by the Manicaland general population cohort study, who did not have hypertension at baseline in 2012-2013, and who were followed until 2018-2019. In 2012-2013, PD was measured using the Shona Symptom Questionnaire, a screening tool validated for use in Shona-speaking countries including Zimbabwe (cut-off point: 7). Smoking, alcohol consumption and use of drugs (health risk behaviours) were also self-reported. In 2018-2019, participants reported if they had diagnosed with hypertension by a doctor or nurse. Logistic regression was used to assess the association between PD and hypertension.

RESULTS

In 2012, 10.4% of the participants had PD. The odds of new reports of hypertension were 2.04 times greater (95% CI 1.16 to 3.59) among those with PD at baseline, after adjusting for sociodemographic and health risk behaviour variables. Female gender (adjusted odds ratio, AOR 6.89, 95% CI 2.71 to 17.53), older age (AOR 2.67, 95% CI 1.63 to 4.42), and greater wealth (AOR 2.10, 95% CI 1.04 to 4.24 more wealthy, 2.88, 95% CI 1.24 to 6.67 most wealthy) were significant risk factors for hypertension. The AOR for the relationship between PD and hypertension did not differ substantially between models with and without health risk behaviours.

CONCLUSION

PD was associated with an increased risk of later reports of hypertension in the Manicaland cohort. Integrating mental health and hypertension services within primary healthcare may reduce the dual burden of these non-communicable diseases.

Does the place of residence influence your risk of being hypertensive? A study-based on Nepal Demographic and Health Survey

Even though several studies have examined various risk factors for hypertension, residential influence is poorly explored especially in the low-income countries. We aim to investigate the association between residential characteristics and hypertension in resource limited and transitional settings like Nepal. A total of 14,652 individuals aged 15 and above were selected from 2016-Nepal Demographic and Health Survey. Individuals with blood pressure ≥140/90 mmHg or a history of hypertension (as identified by physicians/health professionals) or under antihypertensive medication were defined as hypertensive. Residential characteristics were represented by area level deprivation index, with a higher score representing higher level of deprivation. Association was explored using a two-level logistic regression. We also assessed if residential area modifies the association between individual socio-economic status and hypertension. Area deprivation had a significant inverse association with the risk of hypertension. Individuals from the least deprived areas had higher odds of hypertension compared to highly deprived areas 1.59 (95% CI 1.30, 1.89). Additionally, the association between literacy a proxy of socio-economic status and hypertension varied with a place of residence. Literate individuals from highly deprived areas were likely to have a higher odds of hypertension compared to those with no formal education. In contrast, literate from the least deprived areas had lower odds of hypertension. These results identify counterintuitive patterns of associations between residential characteristics and hypertension in Nepal, as compared with most of the epidemiological data from high-income countries. Differential stages of demographic and nutritional transitions between and within the countries might explain these associations.

Undiagnosed hypertension and its determinants among hypertensive patients in rural districts of northwest Ethiopia: a mediation analysis

BACKGROUND

Early detection of hypertension is associated with improved blood pressure control and a reduced risk of cardiovascular diseases. However, in rural areas of Ethiopia, evidence is scarce where access to healthcare services is low. This study aimed to estimate the proportion of undiagnosed hypertension and identify its determinants and mediators among patients with hypertension in rural northwest Ethiopia.

METHODS

A community-based cross-sectional study was conducted from September to November 2020. A three-stage sampling technique was used to select a total of 2436 study participants. Blood pressure was measured using an aneroid sphygmomanometer two times, 30 min apart. A validated tool was used to assess participants' beliefs and knowledge of hypertension. The proportion, determinants, and mediators of undiagnosed hypertension were determined among patients with hypertension. The regression-based approach used to calculate the direct and indirect effects of determinants of undiagnosed hypertension. Joint significance testing was used to determine the significance of the indirect effect.

RESULTS

The proportion of undiagnosed hypertension was 84.0% (95% CI: 81.4-86.7%). Participants aged 25-34 years (AOR = 6.03; 95% CI: 2.11, 17.29), who drank alcohol (AOR = 2.40; 95% CI: 1.37, 4.20), were overweight (AOR = 0.41; 95% CI: 0.18, 0.98), had a family history of hypertension (AOR = 0.32; 95% CI: 0.20, 0.53), and had comorbidities (AOR = 0.28; 95% CI: 0.15, 0.54) were significantly associated with undiagnosed hypertension. The mediation analysis revealed that hypertension health information mediated 64.1% and 68.2% of the effect of family history of hypertension and comorbidities on undiagnosed hypertension, respectively. Perceived susceptibility to hypertensive disease mediated 33.3% of the total effect of age on undiagnosed hypertension. Health facility visits also mediated the effect of alcohol drinking (14.2%) and comorbidities (12.3%) on undiagnosed hypertension.

CONCLUSION

A higher proportion of hypertensive patients remain undiagnosed. Being young, drinking alcohol, being overweight, having a family history of hypertension, and having comorbidities were significant factors. Hypertension health information, knowledge of hypertensive symptoms, and perceived susceptibility to hypertension were identified as important mediators. Public health interventions aimed at providing adequate hypertension health information, particularly to young adults and drinkers, could improve knowledge and perceived susceptibility to hypertensive disease and reduce the burden of undiagnosed hypertension.

Prevalence and associated factors of undiagnosed hypertension among adults in the Central African Republic

The study aimed to estimate the prevalence and associated factors of undiagnosed hypertension (HTN) among adults in the Central African Republic (CAR). In the cross-sectional 2017 CAR (Bangui and Ombella M'Poko) STEPS survey, 3265 persons aged 25 to 64 years (non-pregnant and with complete blood pressure measurement), responded to an interview, biomedical and physical, including blood pressure, measurements. Undiagnosed HTN was classified as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg among adults who had never been told by a doctor or other health worker that they had raised blood pressure or hypertension and had not been taking antihypertensive medication. Binary logistic regressions are used to estimate factors associated with undiagnosed HTN. Among those with HTN (N = 1373), the proportion of undiagnosed HTN was 69.8% and 30.2% diagnosed HTN. In the adjusted logistic regression analysis, male sex (AOR: 2.12, 95% CI 1.39-3.23), current tobacco use (AOR: 1.58, 95% CI 1.03-2.42), and high physical activity (AOR: 1.93, 95% CI 1.00-3.71) were positively associated, and age (AOR: 0.75, 95% CI 0.59-0.96), and underweight (AOR: 0.58, 95% CI 0.37-0.90) were inversely associated with undiagnosed HTN. In addition, among men, ever screened for glucose (AOR: 0.07, 95% CI 0.02-0.27) was negatively associated with undiagnosed HTN, and among women, married or cohabiting (AOR: 1.20, 95% CI 1.00-1.44), current heavy drinking (AOR: 1.41, 95% CI 1.04-1.91) were positively associated with undiagnosed HTN. Seven in ten of the adult population with HTN had undiagnosed HTN in CAR. Efforts should be reinforced to screen for HTN in the general population.

Determinants affecting utilisation of health services and treatment for children under-5 in rural Nepali health centres: a cross-sectional study

Background

Large inequalities in child health remain in Nepal, with caste, ethnicity and sex being major determinants of deprivation and negative outcomes. The purpose of this study was to explore whether key demographics of under 5s were associated with health seeking behaviours, utilisation of health care, and treatment received.

Methods

Data came from Integrated Management of Neonatal & Childhood Illness (IMNCI) records of 23 health centres across five districts. After digitising the paper records, the data was analysed by district, caste/ethnicity, sex, and age to investigate differences in the time taken to present at a health facility after the onset of symptoms of ARI, diarrhoea and fever; accuracy of diagnosis for pneumonia; and whether the correct treatment was prescribed for pneumonia as per IMNCI guidelines.

Results

From 116 register books spanning 23 health centres, 30,730 child patient records were considered for analysis. The median age of attendance was 18 months (Inter-Quartile Range = 10, 32), while were more male children that attended (55.7% vs. 44.3% for females). There were statistically significant differences for the time taken to attend a health centre between different districts for ARI, diarrhoea and fever, with children in the remote Humla and Mugu districts taking significantly longer to present at a health facility after the onset of symptoms (all p < 0.001, except Mugu for ARI days). Children from underprivileged ethnic groups, Madhesi and Dalit, were less likely to be given a correct diagnosis of pneumonia (p = 0.014), while males were more likely to receive a correct diagnosis than females (73% vs. 67%, p = 0.001). This sex difference remained in the adjusted regression models for diagnosis of pneumonia (p < 0.001) but not for treatment of pneumonia (p = 0.628). All districts, in comparison to Gorkha, had increased odds of correct diagnosis and treatment of pneumonia, but only significant in children from Mugu after adjustment (p ≤ 0.001).

Conclusion

Significant demographic differences were found based on ethnicity, sex, and district when examining health seeking behaviours for ARI, diarrhoea, and fever. Significant associations were seen for these same factors when exploring accuracy of diagnoses of pneumonia, but not for treatment. This study has emphasised the importance of a digitalised healthcare system, where inequalities can be identified without the reliance on anecdotal evidence.

Burden of undiagnosed hypertension and associated factors among adult populations in Wolaita Sodo Town, Wolaita Zone, Southern Ethiopia

Background

Hypertension is defined as two or more measurements of systolic blood pressure equal to or greater than 130 mm Hg or diastolic blood pressure equal to or greater than 80 mm Hg. At the community level, symptoms of hypertension are not often detected in the early stages and it leads to many people being left undiagnosed with the disease. Undiagnosed hypertension increases the risk of complications like heart failure, kidney failure, myocardial infarction, stroke, and premature death. There is a paucity of studies concerning the burden of undiagnosed hypertension in Ethiopia including the study area. Therefore, this study aimed to assess the burden of undiagnosed hypertension among adults in Wolaita Sodo Town, Wolaita Zone, Southern Ethiopia,2021.

Methods and materials

A community-based cross-sectional study involving 662 study participants was conducted at Wolaita Sodo Town from May 3 to July 3, 2021. A systematic random sampling technique was used to select the total number of participants. The data was entered using Epidata version 3, and analyzed by SPSS version 25 respectively. Binary logistic regression was used to check for a possible association. P-values < 0.05 and 95% CI were used on multi-variable analysis as the threshold for the significant statistical association.

Results

A total of 644 have participated in the study giving a response rate of 97.3%. The mean (± SD) age of the study participants was 39.18 (± 10.64) years. This finding showed that the burden of undiagnosed hypertension was 28.8% (95% CI: 24.7–33.2%). Body mass index with overweight (AOR = 2.83, 95% CI: 1.17–6.86), the presence of unrecognized diabetic mellitus (AOR = 1.31 95% CI: 1.11–2.15) habit of alcohol drinking (AOR = 2.91, 95% CI: 1.31–4.48), triglyceride (AOR = 3.48 95% CI: 1.22–9.95), age 31–43 years (AOR = 1.50, 95% CI: 1.02–2.01) were significantly associated factors with undiagnosed hypertension.

Conclusions

The burden of undiagnosed hypertension findings was high. Body mass index with overweight, unrecognized diabetic mellitus the habit of alcohol drinking, triglyceride, and age 31–43 years were the factors with undiagnosed hypertension. These findings suggested that preventing risk factors and screening for hypertension at the community level should be encouraged for early detection, and monitoring of the burden of hypertension with ages more than 30 years old, high body mass index, and undiagnosed diabetic mellitus in the population.

Factors affecting reductions in dietary salt consumption in people of Chinese descent: An integrative review

Aims

To identify and synthesize the evidence on the perceptions of the health effects of dietary salt consumption and barriers to sustaining a salt‐reduced diet for hypertension in Chinese people.

Design

A systematic integrated review integrating quantitative and qualitative studies using the PRISMA guidelines.

Data sources

Three databases, MEDLINE, PubMed and CINAHL, were systematically searched for articles published between January 2001 and July 2020.

Review methods

The quality of the included studies was appraised using the Joanna Briggs Institute's critical appraisal tools for cross‐sectional and qualitative studies. Descriptive analysis and constant comparison methods were used to analyse the extracted data.

Results

Fourteen studies met the inclusion criteria. The synthesized results identified that (i) adequate salt‐related health education had a positive influence on dietary behaviour modifications, (ii) the level of educational exposure to the health benefits of salt reduction influenced Chinese people's perceptions of the health impact associated with high salt intake, (iii) the complexity of salt measurement was a barrier to salt reduction, (iv) salt reduction is a challenge to Chinese food culture, and (v) Chinese migrants may experience linguistic and cultural challenges when they seek appropriate dietary education and advice for hypertension management in their host countries.

Conclusion

There is room for improvement in recognizing and translating the knowledge of salt‐related health issues and the benefits of that knowledge about salt reduction into action. Future nursing interventions should incorporate individuals' cultural needs and the dietary culture of immediate family members.

Impact

This integrative review reveals that unique Chinese customs and practices reduce the effectiveness of salt reduction campaigns. The effects of education vanish without family support, resulting in suboptimal adherence to dietary salt reduction strategies.

The Determinants of Undiagnosed Hypertension Among Indonesian Adults: A Cross-sectional Study Based on the 2014-2015 Indonesia Family Life Survey

Objectives

This study investigated the determinants of undiagnosed hypertension among Indonesian adults.

Methods

This study involved an analysis of secondary data from the 2014 Indonesia Family Life Survey (IFLS) on 5914 Indonesian adults (≥40 years). The determinant variables examined in this cross-sectional study were education level, monthly per capita expenditures (PCE), whether the participant experienced headaches in the morning, and other general health variables. The outcome variable was undiagnosed hypertension, which was defined as participants with hypertension who had not received a hypertension diagnosis from a health professional and had never been prescribed medication for treating hypertension. The data were analyzed using logistic regression.

Results

A total of 3322 participants (56.2%) were found to have undiagnosed hypertension. The odds ratios (ORs) and 95% confidence intervals (CIs) of undiagnosed hypertension were significantly higher among those who completed primary school or lower (OR, 1.60; 95% CI, 1.29 to 1.98), had low monthly PCE (OR, 1.28; 95% CI, 1.13 to 1.43), did not report experiencing headaches in the morning (OR, 1.97; 95% CI, 1.76 to 2.21), and reported a general health status of healthy (OR, 2.05; 95% CI, 1.82 to 2.30) than those who had a higher education level, had high monthly PCE, experienced headaches in the morning, and were unhealthy.

Conclusions

Education level, monthly PCE, the experience of headaches in the morning, and general health status were associated with undiagnosed hypertension. The monitoring system for detecting undiagnosed hypertension cases must be strengthened. Health promotion is also necessary to reduce the prevalence of undiagnosed hypertension.

Acceptability of a mHealth strategy for hypertension management in a low-income and middle-income country setting: a formative qualitative study among patients and healthcare providers

BACKGROUND

Understanding contextual needs and preferences is important for a successful design and effective outcome of a mHealth strategy.

OBJECTIVES

This formative study aimed to explore the perspectives of patients and providers on the acceptability of a mHealth (text message) strategy and elicit preferred features of a mHealth strategy for hypertension management.

DESIGN

A qualitative study was conducted using in-depth interviews and focus group discussions guided by the technology acceptance model.

SETTING

The study was conducted at primary healthcare facilities and at a tertiary level referral hospital in Kathmandu, Nepal.

PARTICIPANTS

A total of 61 participants, patients with hypertension (n=41), their family members (n=5), healthcare workers (n=11) and key informants (n=4) were included. We purposively recruited patients with hypertension aged 30-70 who attended the selected healthcare facilities to obtain maximum variation based on their age, sex and literacy.

RESULTS

The respondents perceived the mHealth strategy to be useful as it would reinforce medication compliance and behaviour change. Participants valued the trustworthiness of information from health authorities that could be delivered privately. Some implementation challenges were identified including a lack of technical manpower, resources for software development, gaps in recording a patient's essential information and digital illiteracy. Solutions proposed were having system-level preparedness for recording the patient's details, establishing a separate technical department in the hospital and involving a family member to assist illiterate/elderly patients. In addition, participants preferred text messages in the local language, containing comprehensive contextual content (disease, treatment, cultural foods and misconceptions) delivered at regular intervals (2-3 times/week) preferably in the morning or evening.

CONCLUSIONS

We found that a simple text messaging strategy was acceptable for hypertension management in this low/middle-income country setting. However, meticulous planning must address the needs of a diverse range of participants to ensure the mHealth strategy is acceptable to wider groups.

Inequalities in Undiagnosed Hypertension Among Adult Population in Bangladesh: Evidence from a Nationally Representative Survey

INTRODUCTION

Bangladesh has experienced a rising trend in hypertension in recent years and women are suffering from this non-communicable disease more than men. About one-fifth of the adult population is suffering from hypertension and almost three-fifth of them are undiagnosed.

AIM

This study aims to assess the prevalence and determinants of undiagnosed hypertension and to examine the extent of socioeconomic inequalities in undiagnosed hypertension among adult Bangladeshi population (≥ 18 years).

METHODS

This study used nationally representative Bangladesh Demographic and Health Survey 2017-18 data. Undiagnosed hypertension was defined as having systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg and was never told by the health professionals to lower/control blood pressure. Multiple logistic regression analysis was performed to assess factors associated with undiagnosed hypertension. Further, socioeconomic inequalities in the prevalence of undiagnosed hypertension were estimated using Concentration Index.

RESULTS

Out of total 3196 hypertensive adults, half (50.1%) were undiagnosed. In the adjusted model, older age, overweight/obesity, female gender, richest wealth quintiles had lower odds of being undiagnosed. Overall concentration index showed that poor patients were disproportionately affected by undiagnosed hypertension (Concentration Index: - 0.103, Standard Error (SE) of Concentration Index: 0.024; P value < 0.001). The poor(Q1)-to-rich(Q5) ratio of 1.3 also demonstrates that poorest hypertensive Bangladeshi adults have higher prevalence of undiagnosed hypertension than their richest counterparts.

CONCLUSION

Awareness building program should be targeted towards adults belong to poor wealth quintiles for checking blood pressure regularly. Hypertension should be diagnosed and treated to prevent further complications.

Undiagnosed elevated blood pressure and its life style related risk factors among adults: Cross sectional survey

BACKGROUND

Globally, high blood pressure (BP) is a main health problem among adult population. High BP is considered as a major risk factor which may lead to many cardiovascular diseases. Globally, it is also the leading cause of death. According to the American Heart Association, a BP of 120/80 mm of Hg is a normal range but when the systolic blood pressure ≥130 and diastolic blood pressure ≥80, it is always labeled as hypertension.

OBJECTIVES

In the present study, the researchers wanted to identify the prevalence of undiagnosed elevated blood pressure in the adult population of Uttarakhand, India and also try to explore its lifestyle-related risk factors.

METHODS

This study was an exploratory survey with a cross-sectional design. Data were collected from 440 participants by using the cluster sampling technique.

RESULTS

The male:female ratio among participants was 1:4 and most of the participants were aged 25-30 years. The study found that the prevalence of high blood pressure was 26%, in which marginal elevated BP prevalence was 16%, hypertension stage I was 7%, and hypertension Stage II was 3% which is significantly higher in number at a young age. Lifestyle-related risk factors showed a significant association of hypertensive status with gender, consumption of balanced diet, and personal habits. This increases the chances of elevated blood pressure in young adults.

CONCLUSION

All health professionals must be sensitized for elevated blood pressure problems among the young adult populations. Elevated blood pressure should be considered as a warning alarm at an early age when prescribing any medication and during any invasive procedure. Awareness should be created among public regarding elevated blood pressure issues at a younger age and motivate people to adopt a healthy and stress-free lifestyle.
