Prevalence and Predictors of Depression Amongst Hypertensive Individuals in Karachi, Pakistan

Self-reported depression and its risk factors among hypertensive patients, Morocco: a cross-sectional study

Hypertensive patients are at an elevated risk of developing mental diseases such as depression, which can impair their quality of life. The purpose of this study is to measure the prevalence of self-reported depression among hypertensive patients treated at primary health care facilities in Marrakech. Between May 2021 and December 2022, a cross-sectional study of 1053 hypertensive patients attending primary health care facilities in Marrakech was conducted. A face-to-face questionnaire was used to collect socio-demographic, behavioral, and clinical data, as well as hypertension treatment characteristics and the care-patient-physician triad. The Patient Health Questionnaire-9 was used to assess self-reported depression. To identify self-reported depression risk factors, multivariate logistic regression was used. Depressive symptoms were reported by 56.1% of hypertensive patients. The patients' average age was 63.2 ± 9.5 years, and 508 (85.9%) were female. Female sex, stress, a low-salt diet, pain and physical discomfort, an urban living environment, a lack of self-monitoring of hypertension, an unsatisfactory relationship with the healthcare system, a family history of hypertension, and the perception of adverse effects of the antihypertensive drug were all associated with self-reported depression. Self-reported depression is prevalent among hypertensive patients in Marrakech. The mental health component should be emphasized while addressing hypertensive patients in primary health care facilities.

Depression and its associated factors among adult hypertensive patients attending follow-up in South Gondar zone public hospitals, Ethiopia, 2023

INTRODUCTION

Depression is the most common public health issue affecting the world's population. Like patients with other chronic medical diseases, hypertensive patients experience many intense emotions which increase their risk for the development of depression. This study aimed to assess the magnitude of depression and its associated factors among hypertensive patients in South Gondar zone governmental hospitals, Northwest Ethiopia, 2023.

METHODS

An institutional-based cross-sectional study was used in government hospitals of South Gondar Zone. A total of 311 patients were sampled randomly and included in the study. Statistical Package for Social Sciences (SPSS) version 25 was used for analysis. Data were analyzed mainly by using descriptive statistics and binary logistics regression.

RESULTS

A total of 311 patients participated with a 100% response rate. Almost half of the participants were female. The mean age of the respondents was 58.85 years. More than 60% of the respondents had a co-morbid illness. Among participants, 83 (26.7%) of hypertensive patients had depression. Being female, age, uneducated, having poor social support, the presence of co-morbid illness and complications, uncontrolled hypertension, having less than or equal to two dietary regimen and duration of hypertension greater than ten years were significantly associated with depression.

CONCLUSION

The magnitude of depression was found to be high. This indicated that depression is a common co-morbid illness among hypertensive patients. Healthcare professionals and other stakeholders should consider and diagnose co-morbid diseases like depression among hypertensive patients. It is also better to give particular emphasis to highly vulnerable groups like females, elders, uneducated and those who have poor social support.

Construction of a machine learning-based risk prediction model for depression in middle-aged and elderly hypertensive people in China: a longitudinal study

Background

Hypertension is a common chronic disease that can trigger symptoms such as anxiety and depression. Therefore, it is essential to predict their risk of depression. The aim of this study is to find the best prediction model and provide effective intervention strategies for health professionals.

Methods

The study subjects were 2733 middle-aged and older adults who participated in the China Health and Retirement Longitudinal Study (CHARLS) between 2018 and 2020. R software was used for Lasso regression analysis to screen the best predictor variables, and logistic regression, random forest and XGBoost models were constructed. Finally, the prediction efficiency of the three models was compared.

Results

In this study, 18 variables were included, and LASSO regression screened out 10 variables that were important for the establishment of the model. Among the three models, Logistic Regression model showed the best performance in various evaluation indicators.

Conclusion

The prediction model based on machine learning can accurately assess the likelihood of depression in middle-aged and elderly patients with hypertension in the next three years. And by combining Logistic regression and nomograms, we were able to provide a clear interpretation of personalized risk predictions.

Association of depression and anxiety with uncontrolled hypertension: A cross-sectional study in Southwest Nigeria

Background

Hypertension is a medical condition of public health concern that increases the risk of chronic noncommunicable diseases and mortalities. In recent years, understanding its coexistence with other comorbidities has been the focus of better management. However, the relationship between hypertension and depression or anxiety has been contentious issue, with diverse findings reported by different studies. Understanding this relationship will be crucial for blood pressure control and reducing the mortality associated with hypertension. Therefore, this study was conducted to determine the association between depression or anxiety and hypertension control.

Methods

A cross-sectional study was conducted among 321 hypertensive patients accessing care in two hospitals. Depression and anxiety symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). The relationship between blood pressure control and depression or anxiety was assessed using binary logistic regression.

Results

The prevalence of depression and anxiety was 12.1% and 23.1%, respectively. Up to 261 (81.3%) participants had uncontrolled blood pressure. Of these 261 participants, 14.2% and 23.4% had depression and anxiety, respectively. Depression was associated with an increased risk of uncontrolled blood pressure after adjusting for sex, smoking cigarettes, age, marital status, and exercise (odds ratio (OR) = 7.751, 95% confidence interval (CI) = 1.79-43.4, P = 0.011).

Conclusion

Depression appears to be independently associated with an increased risk of uncontrolled blood pressure. It is therefore relevant for healthcare providers to assess for depression in patients with hypertension to ensure better hypertensive control.

Prevalence of undiagnosed depression among patients with hypertension: A cross-sectional study of Malaysian primary care perspective

Introduction

This study aimed to determine the prevalence of suspected depression and its associated factors among patients with hypertension in a Malaysian primary care clinic.

Method

This cross-sectional study was conducted in a primary care clinic from 1 June to 31 August 2019 using the Patient Health Questionnaire-9.

Results

The prevalence of suspected depression was 9.0%. The significant predictors of depression were Indian ethnicity (adjusted odd ratio [AOR]: 2.373; confidence interval [CI]: 1.147-4.907), divorce (AOR: 3.5; CI: 1.243-9.860), singleness (AOR: 2.241; CI: 1.182-4.251), heavy episodic drinking (AOR: 7.343; CI: 2.494-21.624), low physical activity level (AOR: 1.921; CI: 1.0932.274), low fibre intake (AOR: 1.836; CI: 1.061-3.178), uncontrolled blood pressure (AOR: 1.800; CI: 1.134-2.858) and presence of hypertension complications (AOR: 3.263; CI: 2.053-5.185).

Conclusion

Primary health care providers must screen for depression among patients with hypertension, particularly those within high-risk groups, and implement interventions that address modifiable risk factors.

Depression and anxiety among people with hypertension on follow-up in Eastern Ethiopia: A multi-center cross-sectional study

Background

People with hypertension have a high risk of developing mental disorders, such as depression and/or anxiety. However, there is a paucity of data regarding comorbid depression and anxiety symptoms among people with hypertension in study settings.

Objective

The study determined the prevalence and associated factors of depression, and anxiety symptoms among people with hypertension on follow-up at public hospitals, in Eastern Ethiopia.

Materials and methods

A cross-sectional study was carried out among 471 people with hypertension who were randomly chosen from four public hospitals in Harar town and the Dire Dawa Administration. The data were collected by interviewer-administered structured questionnaires. A validated nine-item Patient Health Questionnaire and Generalized Anxiety Disorder scales were used to assess depression and anxiety symptoms, respectively. A logistic regression model was used to identify the association among depression, anxiety, and their predictors. An adjusted odds ratio and a 95% confidence interval were used to report the association. The statistical significance was set at a p-value of < 0.05.

Results

Depression and anxiety symptoms were present in 27.2 and 32.7% of people with hypertension, respectively. Being women (AOR = 1.74, 1.09-2.78), having no formal education (AOR = 2.19, 1.19-4.81), presence of other medical illnesses (AOR = 2.23, 1.39-3.56), having a family history of depression (AOR = 2.01, 1.25-3.19), and poor social support (AOR = 2.80, 1.60-5.22) were statistically associated with depressive symptoms, whereas being women (AOR = 1.54, 1.01-2.35), widowed and divorced (AOR = 2.22, 1.41-3.52), presence of other medical illnesses (AOR = 1.64, 1.06-2.53), and poor social support (AOR = 3.54, 2.09-6.01) were statistically associated with anxiety symptoms.

Conclusion

More than a quarter of people with hypertension reported symptoms of depression and anxiety. Findings demonstrated that being a woman, having an additional medical illness and having poor social support were statistically associated with depressive and anxiety symptoms. Regular screening, early detection, and offering the proper intervention should be on top priorities for healthcare professionals.

Anxiety and Depression among Hypertensive Adults in Tertiary Care Hospitals of Nepal

Introduction

Cooccurrence of hypertension and depression/anxiety increases the chance of cardiovascular mortality and morbidity. Therefore, this study is aimed at assessing the prevalence of anxiety and depression and their association with hypertension among hypertensive adults in a tertiary care hospital in Kathmandu, Nepal.

Methods

A descriptive cross-sectional study was conducted using a semistructured self-administered questionnaire based on Hamilton Anxiety and Hamilton Depression Rating Scale. The data was entered in EPI Data and analyzed using descriptive and inferential statistics in SPSS version 22. P value < 0.05 was considered statistically significant.

Results

A total of 260 individuals participated in the study, with a mean age of 42.6 years. About 46% of patients did not have any symptoms of depressed mood, and 73 (28.1%) of the participants experienced feelings of depressed mood only on questioning. Similarly, (151) 58.1% did not have feelings of guilt, and 48 (18.5%) participants who had the feeling of guilt had let people down. Among 260 respondents, most participants ((102) 39.2%) had mild symptoms of anxious mood, followed by (86) 33.1% participants with moderate symptoms. Only (4) 1.5% of participants had severe symptoms. Similarly, the majority of participants ((114) 43.8%) had a mild form of mental and emotional strain, followed by (72) 27.7% with moderate mental and emotional strain while (43) 16.5% had no mental and emotional strain. The occupation and marital status of the hypertensive individual was associated with anxiety and depression (P = ≤0.01).

Conclusion

In conclusion, anxiety and depression were common among patients with hypertension. Anxiety and depression were linked to some of the patients' sociodemographic and clinical features. This study demonstrates that treating hypertension alone is not enough to improve patients' quality of life; mental illness screening among chronically ill individuals is also required.

Psychological Backgrounds of Medically Compromised Patients and Its Implication in Dentistry: A Narrative Review

The number of medically compromised dental patients is increasing every year with the increase in the super-aged population. Many of these patients have underlying psychiatric problems and diseases, which need to be recognized by dental professionals for better treatment outcomes. The aim of this narrative review article is to summarize the psychological and psychiatric backgrounds of medically compromised patients who are frequently visited and taken care of by dentists using findings from recent systematic reviews and meta-analyses. Anxiety and symptoms of depression, post-traumatic stress disorders, panic disorders, poor cognitive functions, and poor quality of life were some of the common psychological backgrounds in medically compromised patients. Additionally, the consequences of these psychological problems and the considerations that need to be taken by the dentist while treating these patients have been discussed. Dental professionals should be aware of and recognize the different psychological backgrounds of medically compromised dental patients in order to provide appropriate dental treatment and to prevent oral conditions from worsening.

Depression and associated risk factors among hypertensive patients in primary health care centers in Dammam, Kingdom of Saudi Arabia

Introduction

depression is a common mental illness and Hypertension is a chronic disease and due to the negligence depression is co-morbidity with hypertension. The aim of this study was to determine the prevalence of depression and its associated factor among hypertensive patients in Dammam.

Methods

it was a cross-sectional study and 342 hypertensive patients were selected from primary health care centers in Dammam, KSA. Beck Depression Inventory scale was used to determine the depression. The logistic regression analysis was used to assess the correlation between depression (dependent) and other variables. The P-value of less than 0.05 has been set to be statistically significant.

Results

the proportion of depression with various degrees of severity among study participants was 19.6%. After Adjustment of covariates, older age [aOR 3.33, 95% CI 1.22-9.10; p= 0.019,low income [a OR 3.19, 95% CI 1.02-9.11; p= 0.003, illiterate [aOR 3.41, 95% CI 1.09-7.65; p= 0.005], physical inactivity [aOR 2.65, 95% CI 1.21-9.65; p= 0.051], ever smoker [aOR 2.99, 95% CI 1.09-3.77; p= 0.002], long standing hypertension > 3 years [aOR 3.765, 95% CI 1.01-7.10; p= 0.049] were more likely significantly associated with depression among hypertensive patients.

Conclusion

depression is common among hypertensive patients in our setting. The associated multiple risk factors are older age, low income (< 3000 SR), physical inactivity, long standing hypertension.

Undiagnosed Depression among Hypertensive Individuals in Gaza: A Cross-sectional Survey from Palestine

BACKGROUND

The aim of this study was to estimate the prevalence and to determine the associated factors of undiagnosed depression amongst hypertensive patients (HTNP) at primary health care centers (PHCC) in Gaza.

METHODS

A cross-sectional survey was conducted including 538 HTNP as a recruitment phase of a clustered randomized controlled trial. Data were collected through face-to-face structured interview, and depression status was assessed by Beck's Depression Inventory (BDI-II). Data were analyzed by STATA version 14 using standard complex survey analyses, accounted for unresponsiveness and clustering approach. Generalized linear regression analysis was performed to assess associations.

RESULTS

The prevalence of undiagnosed clinical depression was 11.6% (95% confidence interval [CI]: 8.1, 16.3). Moreover, prevalence of 15.4% (95% CI: 10.8, 21.6) was found for mild depression symptoms. We found that non-adherence to antihypertensive medications (AHTNM) (β = 0.9, 95% CI: 0.17, 1.7), having more health-care system support (β = 2.8, 95% CI: 1.6, 3.9) and number of AHTNM (β = 1.5, 95% CI: 0.6, 2.5) remain significantly positively associated with BDI-II score. On the other hand, older age (β = -0.1, 95% CI: -0.2, -0.02), having better social support (β = -6.8, 95% CI: -8.9, -4.7) and having stronger patient-doctor relationship (β = -4.1, 95% CI: -6.9, -1.2) kept significantly negative association.

CONCLUSION

The prevalence of undiagnosed depression was about one-quarter of all cases; half of them were moderate to severe. Routine screening of depression status should be a part of the care of HTNP in PHCC.

Epidemiology of depressive disorders in people living with hypertension in Africa: a systematic review and meta-analysis

OBJECTIVES

Better knowledge of epidemiology of depressive disorders in people living with hypertension can help to implement pertinent strategies to address its burden. The objective was to estimate the prevalence of depressive disorders and symptoms in people living with hypertension in Africa.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PubMed, EMBASE, African Index Medicus, African Journals OnLine were searched up to 31 January 2020, regardless of the language of publication.

ELIGIBILITY CRITERIA

We included studies conducted among adult patients with hypertension (≥18 years) living in Africa and reporting the prevalence of depressive disorders and symptoms.

DATA EXTRACTION AND SYNTHESIS

Two independent investigators selected studies, extracted data and assessed the methodological quality of included studies by using the tools developed by Joanna Briggs Institute. Multivariate random-effects meta-analysis served to pool data by considering the variability between diagnostic tools used to identify patients with depressive disorders or symptoms.

RESULTS

We included 11 studies with 5299 adults with hypertension. Data were collected between 2002 and 2017, from South Africa, Nigeria, Ghana, Ethiopia and Burkina Faso. The mean age varied between 50.3 years and 59.6 years. The proportion of men ranged from 28% to 54%. The adjusted prevalence of depressive disorders taking into account the variance between diagnostic tools was 17.9% (95% CI 13.0% to 23.4%). The prevalence of depressive symptoms and major depressive symptoms was 33.3% (95% CI 9.9% to 61.6%) and 7.8% (95% CI 3.0% to 14.5%), respectively. There was heterogeneity attributable to the diagnostic tools for depressive disorders and symptoms. There was no publication bias.

CONCLUSION

Notwithstanding the representativeness lack of some (sub) regions of Africa, weakening the generalisability of findings to the entire region; depressive disorders and symptoms are prevalent in people living with hypertension in Africa, indicating that strategies from clinicians, researchers and public health makers are needed to reduce its burden in the region.

Older adults with hypertension have increased risk of depression compared to their younger counterparts: Evidence from the World Health Organization study of Global Ageing and Adult Health Wave 2 in Ghana

BACKGROUND

Depression and hypertension interact through a complex interplay of social, behavioral and biological factors. Despite the huge burden of hypertension in the African sub-region, very little information exists on depression among hypertensive patients. This study assessed the prevalence and factors associated with depression among young and older adult hypertensive patients in Ghana.

METHOD

Data from the World Health Organization Study on Global AGEing and Adult Health wave 2 (2014/2015) for Ghana was used. Depression was estimated among participants with blood pressure 140/90mmHg and above. Weighted descriptive statistics and logistic regression with adjusted predictions were carried out. The analysis was performed using Stata 15.

RESULT

The overall prevalence of depression was 6.3%. Older hypertensive patients had almost twice the prevalence of depression compared with younger patients (8.4% vs 4.5%). The factors which predicted depression among hypertensive patients were educational level, marital status, religion, region of residence, work status, self-rated health (SRH), and unhealthy lifestyle. Participants with no religion were more than 7 times likely to be depressed compared with Christians [aOR(95%CI)=7.52(2.11-26.8)]. Those in the Volta region were more than 8 times likely to be depressed compared to those in the Greater Accra region [aOR(95%CI)=8.58(2.51-29.3)].

CONCLUSION

Older adult hypertensive patients were more likely to experience depressive symptoms. Multiple factors predicted depression in both young and old hypertensive patients; thus a comprehensive care package including psychological support for patients with hypertension is essential for optimum clinical management.

Social capital, depressive symptoms, and perceived quality of care among hypertensive patients in primary care

Background

Depression is an important issue in the management of hypertension. However, little attention has been paid to addressing such aspects of psychological health among patients with hypertension. We aimed to estimate the prevalence of depressive symptoms among patients with hypertension in primary care settings and to identify the potential role of social capital in predicting depressive symptoms. The influence of psychological well-being on the perceived quality of hypertensive care was also examined.

Methods

In Shenzhen, China, an on-site cross-sectional study was conducted from March to September 2017. In total, 1046 respondents completed a face-to-face survey interview. We examined the associations between social capital, depressive symptoms, and perceived quality of care.

Results

The results showed that 10.7% of patients with hypertension who attended primary care facilities had depressive symptoms. Two components of social capital—social ties (9.63 vs. 10.67; OR = 1.314, 95% CI 1.165–1.483; P < .001) and trust (3.46 vs. 3.89; OR = 2.535, 95% CI 1.741–3.691; P < .001)—were protective factors for depression among patients with hypertension in primary care settings. We also found that depressive symptoms were negatively associated with perceived quality of care (30.5 vs. 32.5; β = 1.341, 95% CI 0.463–2.219; P = .003)..

Conclusions

We found inverse associations between depressive symptoms and perceived quality of care and between social capital and the occurrence of symptoms of depression. Our findings suggest that strategies addressing both hypertension and depressive symptoms should be implemented to better manage hypertension. Appropriate social interventions should be designed and implemented.

Physical Comorbidity and Health Literacy Mediate the Relationship Between Social Support and Depression Among Patients With Hypertension

Depression is a common comorbidity among patients with hypertension. Patients with hypertension and depression have worse health outcomes compared to those without depression. The combined effects of social support, physical comorbidity, and health literacy on depression among individuals with hypertension remain unclear. A survey was conducted between December 2017 and May 2018 to investigate the relationships among social support, physical comorbidity, health literacy, and depression in a population of patients with hypertension in rural areas of Sichuan province, China. Multiple linear regression was used to examine factors that influenced depression, and structural equation modeling (SEM) was used to examine the relationships among the four study variables. The mean scores of 549 patients with hypertension were 37.17 ± 6.84 for social support, 14.62 ± 6.26 for health literacy, and 3.56 ± 3.05 for depression; furthermore, 34.2% of participants had physical comorbidity. Gender and per capita annual family income were significantly associated with depression. Physical comorbidity was directly positively related to depression while health literacy was directly negatively related to depression. Social support had an indirect negative association with depression by the mediating effects of health literacy and physical comorbidity. Adequate social support and health literacy, and less physical comorbidity could potentially contribute to reducing depression. The study highlights the importance of social support in maintaining mental health among patients with hypertension. Strategies that target the enhancement of social support and health literacy should be prioritized to relieve depression among patients with hypertension. More attention should be paid to women, low-income individuals, and patients with physical comorbidities.

Magnitude and Associated Factors of Depression Among Hypertensive Patients Attending Treatment Follow Up in Chronic OPD at Hawassa University Comprehensive Specialized Hospital, Hawassa, Southern Ethiopia

Background

Hypertension and depression are among the most common public health issues affecting the population around the world. Like patients with other chronic medical conditions, hypertensive patients experience many intense emotions which increase their risk for the development of depression. Globally, depression is the leading cause of disability and 382 million people suffer worldwide.

Objective

The aim of this study was to assess the magnitude and factors associated with depression among hypertensive patients attending treatment follow up in the chronic OPD at Hawassa University Comprehensive Specialized Hospital (HUCSH) from March to May, 2019.

Methods

An institutional-based cross-sectional study was conducted with 310 hypertensive patients attending treatment follow up at the chronic Out-Patient Department of HUCSH at Hawassa from March to May, 2019. A validated patient health questionnaire (PHQ−9) was used to assess depression. The data were entered using EPI-data version 3.1 and analyzed in SPSS version 22. Binary logistic regression was used to determine the association of independent variables with dependent variables.

Results

The magnitude of depression among hypertension (HPN) patients was found to be 73 (24.7%). The independent predictors were sex 2.6 (1.16, 5.83), age 11.2 (2.98, 42), educational status, social support 2.55 (1.09, 5.94), family history of depression 7.12 (1.48, 34.26), hypertension 7.57 (2.67, 21.44), and medication adherence 11.6 (4.23, 31.78).

Conclusion

The magnitude of depression among HPN patients was high. So, continuous health information dissemination at a different level regarding factors affecting them should be given. Strengthening a referral linkage with a psychiatric unit for psycho-behavioral therapy will bring good clinical outcome. Besides, controlling hypertension was crucial to bring good clinical outcome.

A cross-sectional study of psychiatric morbidity and quality of life among participants utilizing the preventive health-care services of a tertiary hospital

BACKGROUND

The burden of mental disorders has been increasingly recognized and 450 million people globally are suffering from mental illness. Mental-physical comorbidity has adverse effects on the overall outcome. Research is scarce with regard to mental health screening in the context of "preventive health care" in India. Thus, the study aimed to identify the prevalence of mental illness and the effect on quality of life (QOL) among participants attending preventive health-care unit (PHCU).

SETTINGS AND DESIGN

This was a cross-sectional study conducted in PHCU of a tertiary hospital in Puducherry.

MATERIALS AND METHODS

All consecutive participants (>18 years) attending PHCU were included in the study. The Standard for Clinicians' Interview in Psychiatry (SCIP) screening module, Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Level 1 Cross-Cutting Symptom Measure, Mini-Cog, and Quality of Life Enjoyment and Satisfaction Questionnaire were administered. Relevant diagnostic modules of SCIP were applied to participants who screened positive on SCIP. Data analysis was performed using SPSS (version 17.0).

RESULTS

The mean age of participants was 43.38 ± 13.99 years. Of 203 participants enrolled, 28.1% screened positive and 26.1% were confirmed to have psychiatric disorder. About 4% screened positive for cognitive impairment. Most commonly diagnosed disorders were alcohol use disorder and major depressive disorder. The prevalence of depressive disorder was higher in patients with physical disorder. Participants with psychiatric disorder alone or with both psychiatric and physical disorders had significantly poorer QOL (F = 27.13; P < 0.001).

CONCLUSION

One-fourth of the participants attending preventive health-care services were found to have psychiatric disorders. The presence of psychiatric disorder was associated with significantly poorer QOL. This highlights the importance of routine mental health screening in this setting.

Anxiety and Depression among Hypertensive Outpatients in Afghanistan: A Cross-Sectional Study in Andkhoy City

There is a relationship between mental and physical health. Depression and anxiety are linked with the development of several chronic diseases. The purpose of the present study was to determine the prevalence and factors associated with anxiety and depression among adult hypertensive outpatients in Afghanistan. Methods. Two hundred thirty-four consecutive hypertensive patients from December 2015 to August 2016 were recruited to complete the Hospital Anxiety and Depression Scale (HADS) questionnaire, which has scores for classifying the participants having anxiety and depression symptoms. Results. Of the total 234 patients, 81 (34.6%) were males and 153 (65.4%) were females. The mean age was 54.6 ± 12.7 for the hypertensive patients with anxiety and 63.8 ± 15.0 for the hypertensive patients with depression while this figure was 49.5 ± 10.2 for the adult participants in general population in Kabul city (Saeed, 2013). The prevalence of anxiety and depression (42.3% vs. 58.1%) among hypertensive persons is compared with the same mental disorders among Afghan refugees (39.3% vs. 22.1%) in Dalakee Refugee Camp (in Iran) (Hosseini Divkolaye and Burkle, 2017). Of the total participants, 99 had anxiety (42.3%), 136 had depression (58.1%), and 66 had (28.2%) comorbid anxiety-depression. Multivariate analysis was used. For anxiety age, female gender, smoking, diabetes mellitus, and 2 or more chronic diseases had a significant association. For depression, age and diabetes mellitus had a significant association, and for comorbid anxiety, depression, age, diabetes mellitus, and 2 or more chronic diseases had a significant association. Conclusion. This study shows that anxiety and depression are highly prevalent among hypertensive patients in an outpatient clinic in Afghanistan. There was an association between some sociodemographic and clinical characteristics and anxiety and depression. More studies are needed on a national level to inform the development of strategies for the prevention and control of psychological distress among patients with chronic diseases in Afghanistan.

Predictive markers of depression in hypertension

Hypertension and depression, as 2 major public health issues, are closely related. For patients having hypertension, in particular, depression is a risk factor for mortality and jeopardizes their wellbeing. The aim of the study is to apply support vector machine (SVM) learning to blood tests and vital signs to classify patients having hypertension complicated by depression and patients having hypertension alone for the identification of novel markers.Data on patients having both hypertension and depression (n = 147) and patients having hypertension alone (n = 147) were obtained from electronic medical records of admissions containing the records on blood tests and vital signs. Using SVM, we distinguished patients having both hypertension and depression from gender- and age-matched patients having hypertension alone.SVM-based classification achieved 73.5% accuracy by 10-fold cross-validation between patients having both hypertension and depression and those having hypertension alone. Twelve features were selected to compose the optimal feature sets, including body temperature (T), glucose (GLU), creatine kinase (CK), albumin (ALB), hydroxybutyrate dehydrogenase (HBDH), blood urea nitrogen (BUN), uric Acid (UA), creatinine (Crea), cholesterol (TC), total protein (TP), pulse (P), and respiration (R).SVM can be used to distinguish patients having both hypertension and depression from those having hypertension alone. A significant association was identified between depression and blood tests and vital signs. This approach can be helpful for clinical diagnosis of depression, but further studies are needed to verify the role of these candidate markers for depression diagnosis.
