Objectives The objective of this study was to compare depressive symptoms among people with HIV/AIDS and the general population sample. We also assessed the factors associated with depressive symptoms.
Design A comparative cross-sectional study was conducted.
Settings Antiretroviral therapy clinics in three primary healthcare facilities and semi-urban area in Northwest Ethiopia.
Participants A total of 1115 participants (558 people with HIV/AIDS and 557 comparison group) aged 18 years and above were recruited. A total of 1026 participants (530 people with HIV/AIDS and 496 comparison group) completed the interview. We excluded people with known HIV-positive status from the comparison group.
Outcome measure Patient Health Questionnaire (PHQ-9) was used to assess depressive symptoms. The proportion of depressive symptoms was compared between samples of the general population and people with HIV/AIDS using χ2 statistics. Multivariable logistic regression analysis was done to examine the associated factors.
Results The overall prevalence of depressive symptoms was 13.3% (11.2%–15.4%). The prevalence was significantly higher in people with HIV/AIDS compared with the community sample (16.6% vs 12.3%), p=0.001. The difference was also significant in the multivariable logistic regression (OR 1.7). For the overall sample, depressive symptoms were significantly associated with older age, being single, divorced/widowed marital status, and poor social support.
Conclusions Depressive symptoms were higher in people with HIV/AIDS compared with the general population. It is necessary to include mental healthcare and screening for depression in routine HIV/AIDS care.

Strengths and limitations of this study
Having a comparison group is one of the strengths of this study.
Matching of variables between the study and comparison group was not employed.
We were not able to exclude those who are HIV positive but who did not know their status in the comparison group.
Due to the cross-sectional nature of the study, we cannot report causal relationships.
HIV/AIDS continues to be a global public health threat with more than 75 million infections and 32 million AIDS-related deaths since the start of the epidemic.1 2 On the other hand, depression is also a major public health issue and has been considered as a global crisis because of its high contribution to the disease burden, high comorbidities with other medical conditions and associated disabilities.3 4 The comorbidity of depression and HIV/AIDS is common that ranged between 12% and 63%.5–7 This was more pronounced in low resource settings, particularly in sub-Saharan Africa.8 9 A global systematic review and meta-analysis also reported that 31% of people with HIV/AIDS had depression.10 The prevalence of depression in people with HIV/AIDS has been reported as at least twice that of the general population.5 11 The comorbidity between depression and HIV/AIDS has significant consequences in reducing antiretroviral therapy (ART) response that leads to poor quality of life.12–14
The magnitude of depression among HIV/AIDS patients is disproportionately high and its effect is mostly associated with poor disease progress and poor quality of life. This comorbidity is associated with multiple factors including sociodemographic, psychosocial and clinical factors.15–18 For instance, people living with HIV who received ART without HIV counselling and testing services are more likely to develop depression.19 Female gender and recent negative life events are also known contributors to depression in patients with HIV/AIDS.20 However, depression remains underdiagnosed in people with HIV/AIDS.21
Depression can be prevented and treated with available resources at the primary care level. This can be achieved by early detection of depression and identifying important factors associated with depression. To prevent and manage depression in HIV/AIDS, the most important contributing factors need to be explored. Despite the high prevalence and negative consequences of depression among HIV-positive individuals, there is substandard care for depression in most low-income countries’ HIV care programmes.22–24
In Ethiopia, the prevalence of depression was reported 14.6%–48.6% among people living with HIV/AIDS25–27 and 9.1% in the general population.16 However, there was no study that compares depression in HIV-positive people and general population. It is important to see if there is any significant difference in prevalence and possible modifiable factors of depressive symptoms between HIV-positive people and the general population. Therefore, the objectives of this study were:
To assess the level of depressive symptoms among HIV-positive individuals in the ART clinic compared with the general population.
To identify factors associated with depressive symptoms in HIV-positive people and the general population.
Methods and materials
Study design and setting
A comparative cross-sectional study was conducted in Mecha Demographic Surveillance and Field Research Center (MDSFRC). The site is located in Mecha district, Northwest Ethiopia, which is 540 km away from Addis Ababa. MDSFRC is one of the newly established research centres in Bahir Dar University. We recruited people with HIV/AIDS from the adult ART clinics in the district and the comparisons from the general population.
People living with HIV/AIDS aged 18 years and above (69.8% female) in the adult ART clinics of the district were included in the study group. For the general population comparison group, adult residents of Merawi town (a town in Mecha district) aged 18 years and above (48.4% female) who resided for at least 6 months were included. In the comparison group, individuals with known HIV-positive status were excluded.
Data collection and procedures
Data collection was conducted through face-to-face interviews by trained data collectors in March 2018. Clinical data were retrieved from the participants’ medical records. Participants were assured of confidentiality and the anonymity of the questionnaire. Supervisors and data collectors counterchecked the questionnaire every day for its completeness. Sample size was calculated using Epi Info by considering 80% power, 95% CI, 9.1% depression in the general population,16 14.9% depression in HIV-positive people,28 10% non-response rate, and 1:1 ratio of the study and comparative groups to detect 1.7 odds of depression in the study group. The final sample size was 1115 (558 people with HIV/AIDS and 557 comparison group).
In the community comparison group, we selected administrative villages from Merawi town by multi-stage sampling method. We randomly selected the households from the administrative villages using the registration of MDSFRC. We selected one participant using lottery method for those households with more than one eligible participant. For the study group, around 1200 individuals were estimated to attend their ART follow-up during the data collection period. We used a systematic random sampling method to select participants in every two individuals based on their appointment from the ART clinic registration logbook.
Variables and measurements
We measured depressive symptoms by Patient Health Questionnaire-9 (PHQ-9). PHQ-9 is a tool with nine items and validated in the Ethiopian population with good psychometric properties (86% sensitivity and 67% specificity at cut-off point 10).29 Severity of depressive symptoms were also described based on PHQ-9 score (0–4=no depressive symptoms, 5–9=mild depressive symptoms, 10–14=moderate depressive symptoms, 15–19=moderately severe symptoms, 20+=severe depressive symptoms).30 The tool also had good reliability in the current study (Cronbach’s alpha=0.79). We have used PHQ-9 at cut-off score of 10 to identify depressive symptoms that require clinical intervention (moderate to severe depressive symptoms).
The independent variables were:
Sociodemographic variables: sex, age, marital status, educational status and perceived relative income.
Psychosocial variables: social support, problematic alcohol use and khat chewing
HIV-related variables: CD4 level, duration of HIV-positive status and ART use, ART regimen, and presence of opportunistic infections
Social support was assessed using Oslo Social Support Scale (OSSS-3), a three-item scale which has a sum score that ranges from 3 to 14 (poor social support=3–8, intermediate social support=9–11, strong social support=12–14).31 Perceived general quality of life was assessed by asking the participants to rate their quality of life, adapted from WHO’s quality of life assessment tool.32 Relative wealth of the participants was assessed by asking what they perceived about their wealth in relation to others in their neighbourhood.33 Problematic alcohol use was assessed by Alcohol Use Disorder Identification Test–Consumption (AUDIT–C) which is a three-item scale with 72% specificity and 86% sensitivity for men, and 94% specificity and 66% sensitivity for women.34 35
Data entry was done with Epi Info V.7 and analysis was done with SPSS V.21. Chi-squared test was used to compare simple frequencies in between groups. We ran univariate logistic regression for each variable to select variables (p<0.2) for the final model.36 Multivariable logistic regression analysis was done to identify the associated variables. The strength of associations was indicated by OR with a 95% CI. Variables with p values <0.05 were considered as statistically significant.
Socio-demographic characteristics of the participants
From the total of 1115 participants, 1026 (496 from the general population and 530 from the ART clinics) agreed to participate in the study. The reasons for non-response were lack of time to complete the interview (n=47), no interest to participate (n=23) and withdrew from the interview without giving reason (n=19). The mean age of participants was 38.85 years (SD ±10.72) and most of them were in the age group of 25–44 years. The overall divorce and widow rates were 22.9% and 7.6%, respectively. This is significantly higher in the HIV-positive sample (35.5% and 11.3%) as compared with the community sample (9.5% and 3.6%), p<0.001 (table 1).
Psychosocial and related characteristics
Khat (Catha edulis, evergreen, psychoactive leaf which is commonly cultivated in East Africa) was chewed by 6% of participants (9.5% in the community sample and 2.8% in the HIV sample); p<0.001. The HIV-positive participants reported relatively good social support as compared with the community participants (table 2).
HIV and other related characteristics of HIV-positive participants
The median duration since HIV status determined was 84 months (IQR 60 months) with a minimum of 2 months and a maximum of 159 months. The median duration since ART started was 60 months (IQR 60 months) with a minimum of 1 month and a maximum of 144 months. The commonly prescribed ART regimens were 1e and 1c, and opportunistic infections in the last 1 month prior to the data collection time were reported by 12 (2.3%) of participants (table 3).
Prevalence and associated factors of depressive symptoms
The overall prevalence of depressive symptoms was 13.3% (11.2%–15.4%). The prevalence was significantly higher in people with HIV/AIDS, 16.6% (13.4%–19.8%) as compared with the community sample, 9.7% (7.1%–12.3%), p=0.001. Variables significantly associated with depressive symptoms were older age (adjusted OR (AOR) 2.3, 95% CI 1.1 to 5.1), HIV-positive sample (AOR 1.7, 95% CI 1.1 to 2.6), being single (AOR 1.9, 95% CI 1.1 to 3.5), divorced/widowed (AOR 2.3, 95% CI 1.5 to 3.5) and poor social support (AOR 3.9, 95% CI 1.7 to 9.8) (table 4).
This study reported that the prevalence of moderate to severe depressive symptoms is significantly higher in HIV-positive participants (16.6%) compared with the general population sample (9.7%). This variation was also indicated in the multivariable logistic regression analysis where the odds of depressive symptoms in people with HIV/AIDS was 1.7 times higher than the community sample. The additional burdens in HIV-positive participants including opportunistic infections, ART drug side effects and lower level of CD4 count (54.5% of HIV-positive participants have less than 500 CD4) may contribute to this increased prevalence of depressive symptoms in the HIV-positive sample. The finding is in line with the Chinese study (18.33%),37 higher than Ugandan (8.1%) and US (12.2%)38 39 studies, and lower than the Cameroon study (26.7%) and other sub-Saharan countries (26%–28%).40–42
Multiple conditions including HIV-related stigma,43–45 poor adherence to antiretroviral therapy46–48 and the direct effect of the virus49 are possible reasons for the excess odds of depressive symptoms in HIV-positive individuals. New perspectives towards non-medical services and resource allocation,50 and interventions focusing on reduction of risk behaviour and social stigma would decrease the prevalence of depressive symptoms in HIV-positive individuals.51 The advancements in HIV prevention and treatment are becoming promising in ending the HIV epidemic. However, this might be difficult to achieve without addressing depression and other mental health issues in HIV/AIDS care.
Marital status, age and social support were important factors associated with depressive symptoms in the overall sample of this study. The odds of depressive symptoms in single and divorced/widowed participants was nearly twofold as compared with their married counterparts. Marital tragedies are the most stressful events52 that can lead to a sense of insecurity and hopelessness. The odds of having depressive symptoms at the age of 45 years and above was more than twofold as compared with those with younger age (25 years and below). Poor social support is also strongly and positively associated with depressive symptoms in which participants with poor social support were about four times more likely to have depressive symptoms compared with participants with high social support. Social interaction between family members and the family’s ability to react positively to life changes are important to reassuring individuals and maintaining social cohesion.53 On the other hand, if this social connectedness gets loose, the individual might feel lonely and depressed. This finding is supported by the study in Ethiopia and other sub-Saharan countries.41 54
In general, this study provided evidence about depressive symptoms in patients with HIV/AIDS by comparing it with the general population. In the current study, gender, perceived quality of life compared with others, and substance use (khat chewing and alcohol do not involve intravenous administration) were not statistically significant. However, recent finding indicates HIV-positive individuals with drug injection were more likely to have depression.55
The study has some limitations to take into consideration in interpretations of the result. The first limitation is with matching. It would have been better if we did a matching of important variables for depression such as sex and age in both groups. The other potential limitation is that we did not conduct HIV testing in the general population comparison group to exclude those with positive HIV test results. Although we excluded those who reported their HIV-positive status in the comparison group, we were not able to exclude those who are HIV positive but who did not know their status.
Depressive symptoms are significantly higher in people with HIV/AIDS compared with the general population. The higher prevalence of depressive symptoms in people with HIV/AIDS is an important public health issue that urges the incorporation of mental healthcare and depression screening in routine HIV/AIDS care.
