Abstract

Background: Anxiety and depression are common among patients with hypertension. However, they are still unrecognized and untreated especially in developing countries. Identifying factors associated with anxiety and depression is helpful for early screening and management. Presence of depression and anxiety among hypertensive patients lead to lack of adherence to treatment and poor compliance to lifestyle adjustments, which increase patient’s risk of morbidity and mortality. 
Objectives: - To assess the magnitude and associated factors of depression and anxiety among people with hypertension in Hawassa city public hospitals, Sidama region, Ethiopia, 2022.
Method: A Hospital-based cross-sectional study was conducted in selected public Hospitals in Hawassa City Administration from April to August 2022. A total of 397 participants who have been followed hypertensive clinic were selected by systematic sampling. Depression and anxiety were assessed through Hospital Anxiety and Depression Scale. Pretested and structured questionnaire was used for data collection with face-to-face interview technique. Data were entered in to EPI info version 3.5.3 and exported to SPSS version 20 for further analysis. Descriptive statistics was used to explore the data in relation to relevant variables. Binary logistic regression analysis was employed. Odds ratio with 95% confidence intervals (CI) was computed to assess the magnitude of anxiety and depression among hypertensive patients attending public Hospitals in Hawassa city administration. Associations were determined by using AOR at 95% CI and p value less than or equal to 0.05.
Result – The prevalence of anxiety, depression and comorbid anxiety and depression were found to be 37.8%, 29.5% and 16.5% respectively.  Factors found to have significant association with depression were being female gender, presence of comorbid illnesses and with long duration of hypertension. Factors found to have significant association with anxiety were being female sex, presence of comorbid illnesses and retired and non-paid job. Similarly being female gender, presence of chronic comorbid illnesses, family history of depression, ever alcohol drinking were associated with comorbid anxiety and depression. 
Conclusion and Recommendation: - High prevalence of anxiety and depression were observed in Public Hospitals of Hawassa city administration. They are significantly associated with socio-demographic, clinical and behavioral factors. Clinicians and health sector leaders should consider mental health status of hypertensive patients. 
 

1.Introduction

Background: Today world is facing double burden of diseases, especially with increasing burden of non-communicable disease including cardiovascular diseases, cancer, chronic respiratory diseases and diabetes [1]. In 2016 non communicable diseases were estimated to account for 71% of the 57 million global deaths in addition to that 78% of all NCD deaths, and 85% of premature adult NCD deaths, occurred in low- and middle-income countries (LMICs) [2]. The burden of anxiety and depression among hypertensive patients are rapidly increasing. Anxiety and depression are common disorders that result in mental illnesses. Hypertensive patients suffering from anxiety and depression are at greater risk to develop cardiovascular diseases [3]. The total number of people living with anxiety and depression in the world are estimated to 322 million and 264 million, respectively [1].  Anxiety and depression are common in diabetic, hypertensive and heart failure patients than the general population [2]. 

Hypertension, also known as high or raised blood pressure, is a condition in which the blood vessels have persistently raised pressure. This raised blood pressure is one of the leading risk factors for different cardiovascular diseases. If left untreated hypertension contributes high financial burden, myocardial infarction, stroke, renal failure and burden to health systems [4]. 

 The highest prevalence of hypertension was observed in the African Region at 46% of adults aged 25 and above [5]. In Ethiopia NCDs are estimated to account for 39% of all deaths, in 2016. Around 275,000 deaths were due to NCDs in 2015 and nearly 24% were adults 18 years and over expected to have raised blood pressure [1, 2]. 

Anxiety and depression have a direct relation with chronic illnesses [6, 7]. A meta-analysis study conducted reported that anxiety and depression were common among patients with chronic illness in both developed and developing countries [8]. By 2020, 5.7% increment were expected in the global burden of disease because of depression and by 2030 it become the leading cause of disability worldwide, reduce individual’s productivity at work or school performance and at severe stages it can lead to suicide [6].

Depression and anxiety can cause chronic stimulation of sympathetic nervous system that results in insulin resistance and affects the function of the heart and blood vessels [9]. Epidemiological studies suggest that relationship of psychological features, such as anxiety and depression and cardiovascular diseases may involve impaired regulation of the heart by autonomic nervous system [10]. 

There are different factors that influence depressive symptoms among patients with cardiovascular disorders. Both depressive symptoms and hypertension are psycho-physiologic phenomena [8]. The age, lack of social support, residence, educational level, sex and high numbers of prescribed medications were found as contributing factors for the development of depressive symptoms in hypertensive patients [10, 11]. 

Those with non-comorbid depressive disorder, non-comorbid anxiety disorder, and comorbid depression-anxiety were more likely to have hypertension compared to persons with neither a depressive nor an anxiety disorder [12].

1.2 statement of the problem

Hypertensive patients with chronic diseases are at higher risk to develop mental illnesses. Differently from general population, depression is more common among patients affected chronic illness (13). Having a chronic illness puts patients at higher risk of anxiety and depression [14]. A facility based cross-sectional study done in Ghana and Nigeria in 2013 revealed the prevalence of depression to be 41.7% and 26.6% respectively [32]. Another similar study done in Ethiopia showed the prevalence of depression to be 24.7% and anxiety 28.5% among hypertensive patients [34].

There were different factors known to affect the magnitude of anxiety, depression and comorbid anxiety and depression among hypertensive patients. A systematic review study done in Ethiopia showed that sex, age and duration of diseases were found to be contributing factors depression [17]. Also, there are other associated factors with anxiety and depression among hypertensive patients, such as low income, lack of social support, educational status and residence of the patients [11, 18, 19, 20, 21].

Anxiety and depression have various undesirable health significances in patients with chronic illnesses. Medication non adherence, rapid disease progression, interfere with a person’s ability to function day to day activities and poor quality of life as well as poor health outcomes were effects of untreated and unrecognized anxiety and depression [9, 10, 22]. 

The control of hypertension may insure on individuals being adherent to measure to reduce behavioral risk factors and drug treatment as prescribed [23]. Patient adherence with medical advice is one of the strategies in the management of chronic diseases, like hypertension that can be determined by Anxiety as well as depression [24, 25, 26]. 

Recognizing contributing factors of anxiety and depression in hypertensive patients is supportive for early identification of cases and management. Nonetheless, magnitude and factors associated with depression and anxiety in patients with hypertension are not evaluated sufficiently in developing countries including Ethiopia. Thus, current study was aimed to assess magnitude associated factors with anxiety and depression among patients attending hypertension follow up clinics in Hawassa city public Hospital, Sidama, Ethiopia.

1.3 Significance of the study

This research was expected to put a ground for the identification of the magnitude of anxiety, depression and comorbid anxiety-depression among hypertensive patients in the study area. And it also planned to determine contributing factors of depression and anxiety among hypertensive patients that will help to improve patient’s compliance to recommended proper lifestyle and adherence to anti-hypertensive treatment they are on, so that severity can be avoided. The findings of current study will also help hospitals and other similar institutes to better diagnose similar issues for furtherance in their process and also help as baseline information for future research. The study results will help to increase awareness among health care professionals for the early screening and treatment of this problem also.

4.5 Prevalence of comorbid anxiety-depression among hypertensive patients

From total participants of the study 16.5% (95% CI; 13.3-19.9%) of them had comorbid anxiety and depression and 50.9% (95% CI; 45.9-55.8%) of the participants had either depression or anxiety. In addition to this, 43.5% of hypertensive patients with depression had comorbid anxiety and 55.8% of the hypertensive patients with anxiety had comorbid depression.

4.6 Factors associated with depression, anxiety and comorbid anxiety and depression among hypertensive patients

4.6.1 Factors associated with depression

Bivariate logistic regression analysis was done to examine the association of each independent variables with depression. Variables with P-value of less than 0.25 on bivariate logistic regression, sex, marital status, monthly income, presence of comorbid illnesses, blood pressure control, duration of hypertension, family history of depression and current alcohol drinking status were entered into multivariable logistic regression. In the final 

model the strength of association was measured by AOR with 95% confidence interval and variables associated with depression with P-value <=0.05 considered as significantly associated. 

As shown in table 5, in multivariable logistic regression analysis, females were 5.4 times more likely to have depression compared to males. Married subjects had 75% reduced odds of having depression compared to those who were single. Those who had comorbid illnesses were 3 times more likely to have depression when compared to those who have no any comorbid illnesses. And those with uncontrolled blood pressure were 2.8 times more likely to have depression when compared with those subjects who have controlled blood pressure. Participants with duration of hypertension 5 to 10 years are 3.2 times and more than 10 years are 5.8 times more likely to have depression compared to patients with less than 5 years of hypertension duration. Participants with family history of hypertension were 4.5 times more likely to have depression when compared to their counterparts. Currently alcohol drinker participants were 1.8 times more likely to have depression compared to those who were not alcohol drinkers currently.

4.6.2 Factors associated with anxiety

Bivariate logistic regression analysis was done to examine the association of each independent variable with anxiety. Variables with P-value of less than 0.25 on bivariate logistic regression, sex, employment status, monthly income, presence of comorbid illnesses, blood pressure control, duration of hypertension, family history of depression, current cigarette smoking, current alcohol drinking status and physical activity, were entered into multivariable logistic regression. In the final model the strength of association was measured by OR with 95% confidence interval and variables associated with anxiety with P-value <0>

As seen in table 6, in multivariable logistic regression analysis, female hypertensive subjects are 3.1 times more likely to have anxiety when compared with males. Those who are retired are 6.4 times and with non-paid job are 6.5 times more likely to have anxiety compared to subjects who work in non-governmental organization. 

Participants with comorbid illnesses are 3.1 times more likely to have anxiety when compared with participants who have no comorbid illnesses. Subjects with duration of hypertension 5 to 10 years were 2.7 times more likely to have anxiety compared to those with duration of hypertension less than 5 years. And participants with duration of hypertension more than 10 years were 4.9 times more likely to have anxiety compared to those with duration of hypertension less than 5 years. Those participants who drink alcohol currently were 2.2 times more likely to have anxiety compared with their counterparts.

4.6.3 Factors associated with comorbid depression and anxiety

As described in table 9, bivariate logistic regression analysis was done to examine the association of each independent variable with comorbid depression and anxiety. Variables with P-value of less than 0.25 on bivariate logistic regression, sex, monthly income, presence of comorbidities illness, blood pressure control, duration of hypertension, family history of hypertension, family history of depression, current smoking and ever alcohol drinking status, were entered into multivariable logistic regression. In the final model the strength of association was measured by OR with 95% confidence interval and variables associated with comorbid depression and anxiety with P-value <0>

Accordingly female hypertensive patients were 9.9 times more likely to have comorbid depression and anxiety when compared with male hypertensive subjects. Subjects with comorbid illnesses were 2.4 times more likely to have comorbid depression and anxiety when compared with hypertensive patients who have no any comorbid illnesses. 

Hypertensive patients with duration of hypertension more than 10 years were 5.2 times more likely to have comorbid depression and anxiety compared to participants with duration of hypertension less than 5 years. 

Study subjects with family history of hypertension were 4.5 times more likely to have comorbid depression and anxiety when compare with subjects who have no family history of hypertension. Participants who ever drink alcohol were 3.3 times more likely to have comorbid depression and anxiety when compared to those participants with no lifetime alcohol drinking status.

Table 7: Factors associated with comorbid anxiety and depression among hypertensive patients attending public hospitals in Hawassa, Sidama, Ethiopia, 2022

5. Discussion

The current study was carried out to assess the magnitude and factors associated with depression and anxiety among hypertensive patients attending selected public hospitals in Hawassa city administration. The result revealed that the prevalence of depression among hypertensive patients to be 37.8%, and it is consistent with study result in Ghana 41.7% [32], Pakistan 40.1 [28] and India 41% [27].

In contrary to this finding, the current finding is lower than study in Afghanistan which was 58.1% [29]. The reason for the difference could be the health facilities set up of the countries. In opposite to this study, the lower prevalence of depression obtained from the study conducted in Jimma, Western Ethiopia, in 2019 found to be 24.7% [33]. Studies in Ghana and Nigeria found prevalence of depression to be 11% [26] and 26.6% [32] respectively. The difference might be due to geographical variations, readiness of health facilities and method of assessment of depression. 

The prevalence of anxiety among hypertensive patients was found to be 29.5%, which is nearly consistent with study conducted in Menelik Hospital, in Ethiopia, in 2016, which was 28.5% of participants with hypertension to have anxiety (34). However, the finding of this study is smaller than a study in Afghanistan 42.3 %[29] and Saudi Arabia 38.4 %[31]. The difference could arise from cultural and environmental difference. In contrary to this study, the prevalence of anxiety among hypertensive patients in Ghana was found to be 57% [20]. The possible reason for these variations might be due to difference in instrument and the settings studies conducted [29]. 

The finding of this study showed that 16.5% of participants have comorbid depression and anxiety and half of subjects suffer from either anxiety or depression. High prevalence of comorbid anxiety and depression reported from a study in Afghanistan which is 28.2% [29], similarly a study in Saudi Arabia reported 29.5% to have comorbid anxiety and depression and prevalence of either of the disorders were 57.3% [31]. The above-mentioned reasons could explain the difference observed.

According to this study, hypertensive females have 5.4 times increased chance to be depressed. This is higher than a study finding from South Africa, which is 3.5 times [26] and much higher than study findings from Jimma Medical center, Western Ethiopia, a 2.6 times increased risk [33]. Similarly, majority of literature suggests the same findings [27, 28, 30, 31, 35]. Possible explanation for this variation might be socio-cultural variation. In addition to this, higher magnitude of depression in females could rise from changes in sex hormone and influences in females related to social norms and gender issues, which are parents restrictive behaviors towards their daughter than sons affects their daughters senses of self-control and self-esteem and make them vulnerable to depression. Sexual and domestic violence could also contribute for the higher risks in females [25]. 

With respect to marital status, married hypertensive patients have 75% reduced chance being depressed. The study in India, Bosnia and Herzegovina reported same findings [27, 35]. Differently from this, studies in Ethiopia, South Africa, Pakistan, Afghanistan and Ghana found that marital status of hypertensive patients have no association with their depression status [26, 27, 28, 29, 32]. The possible reason for this could be married hypertensive patients are being stable, sharing the increasing burden of living cost and retaining positive healthy behaviors. 

The study finding revealed that hypertensive patients with comorbid illnesses are 3 times more likely to be depressed. Similar result was obtained from the study conducted in Afghanistan that hypertensive patients with comorbid diabetes were 22.7 times more likely to have depressed [29]. A possible reason could be that comorbid illnesses may increase the stress. 

In respect to blood pressure control, the result showed that hypertensive patient with blood pressure is uncontrolled are 2.8 times more likely to be depressed. The finding of this study is consistent with a study in Saudi Arabia [30]. It could be because of poor adherence of hypertensive patients to their medications result in poor blood pressure. 

Also this study examined that hypertensive patient with duration of hypertension 5 to 10 years and more than 10 years have 3.2 and 5.8 times increased chance of being depressed respectively. This finding is consistent with previous study conducted in Pakistan [27]. The reason might be that as time of being comorbid increase the worries also increase and the client might be depressed. 

A family history of depression are 4.5 times more like to have depression. Similar finding was also obtained from the study conducted at Jimma, Western Ethiopia, hypertensive patients with family history of depression have 7 times higher chance of being depressed [33]. The reason might be that similarity in genetically factors. 

The hypertensive patient who drink alcohol have 1.8 times increased chance of being depressed. This finding is similar with study findings in South Africa, which was 1.9 times higher chance of being depressed [25]. The possible reason for this could be influence of health effect, social problem, economic and productivity loss associated with alcohol increase the risk of depression and anxiety. 

According to this study, female hypertensives are 3.1 times more likely to be anxious. This finding is comparable with study findings in Ethiopia and in South Africa, a 2.57 and 3.2 times higher chance of anxiety among female hypertensives respectively [26, 34]. In addition to this, study conducted in China, found significant association with occurrence and severity of anxiety among female hypertensives patients [21]. The possible explanation could be the higher burden for females, domestic and gender based violence could also contribute. 

Also this study finding showed that study participants who are retired and non-paid job are more likely to be anxious. In contrary to this few studies showed no association of occupational status with hypertensive patient of being anxious were reported [21, 26]. The reason might be retired peoples are less interact with other peoples because of their limited movement which makes them unable to share their ideas and feelings that lead them to feeling of being isolated and ignored.     

The findings of this study also shown that hypertensive patient with duration of hypertension 5 to 10 years and more than 10 years are 2.7 and 4.9 times more likely to be anxious respectively when compared to subjects with duration of hypertension less than 5 years. The result is in line with studies which studied that severity of anxiety increases with duration of hypertension when persists for more than 5 years [21]. The reason might be that due the increase of stress as time increases. 

According to this study, female hypertensive patient were 9.9 times more likely to develop comorbid anxiety and depression. This is also supported with other studies’ result that female hypertensive subject had 12.5 higher odd of being comorbid anxious and depressed compared to male hypertensive subjects [26]. The above suggested reasons for anxiety and depression could explain the higher odd of females to have comorbid anxiety and depression. 

With respect to comorbid illnesses, the study revealed that comorbid illnesses with hypertension to increase the probability of being comorbid anxious and depressed by 2.4 times. This is consistent with the study result obtained from Indian which reported hypertensive subject with comorbid diabetes are 10.2 times more likely to have comorbid anxiety and depression [29].

This study also reported that ever alcohol drinker hypertensive subjects are 3.3 times more likely to have comorbid anxiety and depression compared to their counter parts. The above predicted reason for depression and anxiety might attribute for the higher odds of comorbid anxiety and depression among subjects with comorbid illnesses. 

Strength and Limitation of the study

Current study had numerous strengths. Among these, outcome variables (anxiety and depression) are assessed through validated tools (HADS)it was carried out in representative selected public hospitalsLikewise there were limitations of the study also. Due to its cross sectional nature of study it was difficult to known temporal relationship, there was possibility of recall bias and since the study was done in institutions, it might not be generalized to the general population with hypertension. 

 Conclusion 

High prevalence of anxiety, depression and their correlate were observed in selected public hospitals of Hawassa city administration. Depression was significantly associated with female gender, being married, presence of comorbid illnesses, uncontrolled blood pressure, duration of hypertension 5 to 10 and more than 10 years, family history of depression and current alcohol drinking. On the other hand, anxiety was found to be significantly associated with the being female gender, presence of comorbid illnesses, duration of hypertension 5 to 10 and more than 10 years, current alcohol drinking, retired and hypertensive subjects with non-paid job. Comorbid anxiety and depression were also found to have significant association with the being female gender, presence of comorbid illnesses, duration of hypertension more than 10 years, family history of depression and drinking alcohol ever. 

Recommendations: Based on the findings of the study the following recommendations are suggested:- Prepare trainings for health professionals to widen their understandings about high burden and determinant factors of anxiety and depression among hypertensives, provide hypertension clinics with anxiety and depression screening tool, educate hypertensive patients about depression and anxiety risks and modifiable factors like alcohol drinking. Providing depression and anxiety screening for those who are at more risk and link to a psychiatric clinic those who are in need. Need for psychiatric evaluation, counseling, and support services for hypertensive patients as an important component for the management of hypertension especially at advanced stage. Finally Researches and policy makers are needed to develop strategies for the prevention and control of psychological distress among patients with hypertension.
