Mental distress in the general population in Zambia: impact of HIV and social factors

Determinants of psychological distress among individuals who are aware of their HIV serostatus in South Africa: findings from the 2017 national HIV prevalence, incidence, behavior, and communication survey

Introduction

Psychological distress is a growing public health challenge among people living with HIV. This study investigated the prevalence of psychological distress among individuals who know their HIV positive or negative serostatus in South Africa using 2017 data from a nationwide cross-sectional household-based population survey.

Methods

The data for this secondary analysis was collected using a multi-stage stratified cluster randomized sampling design. Multivariable backward stepwise generalized linear regression models were fitted to determine factors associated with psychological distress as measured by the Kessler Scale (K10) among HIV-positive and HIV-negative individuals who know their serostatus in South Africa.

Results

Of 18,662 participants, psychological distress was 27.4% (95% CI: 25.3-29.7) among those HIV-positive and 20.1% (95% C: 18.8-21.4) among those HIV-negative. The odds of psychological distress were significantly higher among HIV-positive individuals who rated their health as fair/poor [AOR = 1.22 (95% CI: 1.09-1.35), p < 0.001], and the odds were lower among those residing in rural formal/farm areas [AOR = 0.85 (95% CI: 0.78-0.93), p < 0.001], and those with tertiary education level [AOR = 0.88 (95% CI: 0.78-0.99), p = 0.033]. The odds of psychological distress in HIV-negative individuals were significantly higher among females than males [AOR = 1.09 (95% CI: 1.05-1.14), p < 0.001], high-risk alcohol drinkers [AOR = 1.26 (95% CI: 1.02-1.57), p = 0.035] and hazardous alcohol drinkers [AOR = 1.09 (95% CI: 1.01-1.18), p = 0.028] than abstainers and those who rated their health as fair/poor rather than excellent/good [AOR = 1.18 (95% CI: 1.10-1.26), p < 0.001].

Conclusion

The study underscores the importance of addressing, alcohol misuse and socio-structural inequalities linked to gender and race-based disparities, such as low educational attainment and unemployment, as critical factors associated with psychological distress in the study population.

Prevalence of mental distress in adults with and without a history of tuberculosis in an urban Zambian community

People with tuberculosis (TB) are susceptible to mental distress. Mental distress can be driven by biological and socio-economic factors including poverty. These factors can persist beyond TB treatment completion yet there is minimal evidence about the mental health of TB survivors. A cross-sectional TB prevalence survey of adults was conducted in an urban community in Zambia. Survey participants were administered the five-item Self Reporting Questionnaire (SRQ-5) mental health screening tool to measure mental distress. Associations between primary exposure (history of TB) and other co-variates with mental distress were investigated using logistic regression. Of 3,393 study participants, 120 were TB survivors (3.5%). The overall prevalence of mental distress (SRQ-5 ≥ 4) in the whole study population was 16.9% (95% CI 15.6%-18.1%). Previous TB history was not associated with mental distress (OR 1.20, 95% CI 0.75-1.92, p-value 1.66). Mental distress was associated with being female (OR 1.23 95% CI 1.00-1.51), older age (OR 1.71 95% CI 1.09-2.68) and alcohol abuse (OR 1.81 95% CI 1.19-2.76). Our findings show no association between a previous TB history and mental distress. However, approximately one in six people in the study population screened positive for mental distress.

Validation of the combined Patient Health Questionnaire Anxiety and Depression Scale among people with HIV in Vietnam

BACKGROUND

Our study aims to examine the factor structure, validity, and reliability of the combined scale Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS) among people with HIV (PWH) in Vietnam.

METHODS

Baseline data from an alcohol-reduction intervention trial among ART clients in Thai Nguyen, Vietnam were used for this analysis (n = 1547). A score ≥10 on the PHQ-9, GAD-7 and PHQ-ADS scale was considered having clinically meaningful depression, anxiety and distress symptoms. Factor structure of the combined PHQ-ADS scale was validated using confirmatory factor analysis, and three models were tested: a one-factor, a two-factor, and a bi-factor model. Reliability and construct validity were examined.

RESULTS

The prevalence of clinically meaningful depression and anxiety symptoms was 7% and 2%, respectively, while 19% had distress symptoms. A bi-factor model had the best fit to the data (RMSEA = 0.048; CFI = 0.99; TLI = 0.98). The Omega index of the bi-factor model was 0.97. The scale showed good construct validity through negative associations between depression, anxiety, distress symptoms and quality of life.

CONCLUSIONS

Our study supports the use of a combined scale to measure general distress for PWH, which has good validity, reliability and is unidimensional enough to justify the use of a composite depression and anxiety score.

Qualitative study of patient experiences of mental distress during TB investigation and treatment in Zambia

Background

The mental health and TB syndemic is a topic that remains under-researched with a significant gap in acknowledging and recognizing patient experiences, particularly in the sub-Saharan African region. In this qualitative study conducted in Zambia, we aimed to explore the lived mental health experiences of TB patients focusing on their multi-layered drivers of distress, and by so doing highlighting contextual factors that influence mental distress in TB patients in this setting.

Methods

The study draws on qualitative data collected in 2018 as part of the Tuberculosis Reduction through Expanded Antiretroviral Treatment and Screening for active TB trial (TREATS) being conducted in Zambia. The data was collected through in-depth interviews with former TB patients (n = 80) from 8 urban communities participating in the TREATS trial. Thematic analysis was conducted. Additional quantitative exploratory analysis mapping mental distress symptoms on demographic, social, economic and TB characteristics of participants was conducted.

Results

Most participants (76%) shared that they had experienced some form of mental distress during their TB investigation and treatment period. The reported symptoms ranged in severity. Some participants reported mild distress that did not disrupt their daily lives or ability to adhere to their TB medication, while other participants reported more severe symptoms of distress, for example, 15% of participants shared that they had suicidal ideation and thoughts of self-harm during their time on treatment. Mental distress was driven by unique interactions between individual, social and health level factors most of which were inextricably linked to poverty. Mental distress caused by individual level drivers such as TB morbidity often abated once participants started feeling better, however social, economic and health system level drivers of distress persisted during and beyond TB treatment.

Conclusion

The findings illustrate that mental distress during TB is driven by multi-layered and intersecting stresses, with the economic stress of poverty often being the most powerful driver. Measures are urgently needed to support TB patients during the investigation and treatment phase, including increased availability of mental health services, better social security safety nets during TB treatment, and interventions targeting TB, HIV and mental health stigma.

Effects of Two Alcohol Reduction Interventions on Depression and Anxiety Symptoms of ART Clients in Vietnam

Little is known about the potential mental health impacts of cognitive behavioral therapy and motivational interviewing interventions that focus on alcohol reduction among people with HIV (PWH). Our study aimed to assess the impact of two evidence-based alcohol reduction interventions on depression and anxiety symptoms of antiretroviral therapy (ART) clients with hazardous alcohol use. We conducted a secondary data analysis of data from a three-arm randomized controlled trial among ART clients in Thai Nguyen, Vietnam that evaluated the impacts of two alcohol reduction interventions in Vietnam. ART clients 18 years old or more with hazardous alcohol use (based on the Alcohol Use Disorders Identification Test-Consumption) were enrolled and randomized into one of three arms: Combined intervention, Brief intervention, and Standard of care (SOC). Symptoms of depression, measured with the Patient Health Questionnaire-9, and anxiety, measured with the Generalized Anxiety Disorder-7 scale, were assessed at baseline and 3, 6, and 12 months post-intervention. Generalized estimating equations were used to evaluate the effects of the interventions on depression and anxiety symptoms. The prevalence of depression and anxiety symptoms at baseline was 25.1% and 16.1%, respectively. Decreases in depression and anxiety symptoms were observed in all three arms from baseline to 12-month follow-up. There were no significant differences in depression and anxiety symptoms among participants receiving either intervention, relative to the SOC. Interventions with a dual focus on alcohol and mental health are needed to achieve more pronounced and sustainable improvements in depression and anxiety symptoms for PWH with hazardous alcohol use.

The longitudinal association between depression, anxiety symptoms and HIV outcomes, and the modifying effect of alcohol dependence among ART clients with hazardous alcohol use in Vietnam

INTRODUCTION

Mental health disorders may negatively impact HIV outcomes, such as viral suppression (VS) and antiretroviral (ART) adherence among people with HIV (PWH) with hazardous alcohol use. This study evaluates the longitudinal association between depression, anxiety symptoms, VS and complete ART adherence among ART clients with hazardous alcohol use in Vietnam; and examines alcohol dependence as a modifier in this association.

METHODS

This was a secondary data analysis of a trial for hazardous drinking ART clients in Thai Nguyen, Vietnam. From March 2016 to May 2018, 440 ART clients with an Alcohol Use Disorders Identification Test-Concise (AUDIT-C) score ≥4 for men and ≥3 for women were enrolled. Individuals were randomized to either a combined intervention, a brief intervention or a standard of care. Data on sociodemographics, depression, anxiety symptoms, alcohol use, VS and ART adherence were collected at baseline, three, six, and twelve months. Generalized estimating equation models controlling for intervention exposure were used to estimate time-lagged associations. Risk ratios were estimated using Poisson regression with robust variance estimation.

RESULTS

The mean age of participants was 40.2. The majority was male (96.8%), had at least some secondary school education (85.0%) and had a history of injection drug use (80.9%). No overall effect of depression and anxiety symptoms on VS was observed. When stratified by time, increased anxiety symptoms at six months were associated with VS at 12 months (adjusted risk ratio (aRR) = 1.09; 95% CI 1.02 to 1.17). An increase in depression or anxiety symptoms was associated with a decreased probability of complete ART adherence (depression symptoms: aRR = 0.95; 95% CI: 0.91 to 0.99; anxiety symptoms: aRR = 0.93; 85% CI: 0.88 to 0.99). The negative effects of anxiety symptoms on ART adherence were stronger among participants with alcohol dependence, compared to those without.

CONCLUSIONS

Depression and anxiety symptoms had no overall effect on VS, although they were associated with a lower probability of complete ART adherence. Interventions focusing on mental healthcare for PWH with hazardous alcohol use are needed, and integration of mental healthcare and alcohol reduction should be implemented in HIV primary care settings.

Burden of Depression in Outpatient HIV-Infected adults in Sub-Saharan Africa; Systematic Review and Meta-analysis

Despite the substantial burden of HIV in Africa, and the knowledge that depression causes worse HIV outcomes, the burden of depression in people living with HIV in Africa is unknown. We searched Pubmed and four other databases using key terms: depression, Africa, HIV, and prevalence from 2008 to 2018. We summarized depression prevalence by country. We estimated the burden of depression using our prevalence data and 2018 UNAIDS HIV estimates. Our search yielded 70 articles across 16 African countries. The overall prevalence of major depression in those HIV-infected using a diagnostic interview was 15.3% (95% CI 12.5-17.1%). We estimate that 3.63 million (99.7% CI 3.15-4.19 million) individuals with HIV in Sub-Saharan Africa have major depression and provide country-level estimates. We estimate that 1.57 million (99.7% CI 1.37-1.82 million) DALYs are lost among people with depression and HIV in Sub-Saharan Africa. There is a significant burden of depression in Africans with HIV. Further work to screen for and treat depression in Sub-Saharan Africa is needed to improve HIV outcomes and achieve the 90-90-90 UNAIDS goals.

Social support, mental health needs, and HIV risk behaviors: a gender-specific, correlation study

BACKGROUND

The HIV/AIDS epidemic continues to threaten the health and wellbeing of millions in the United States and worldwide. Syndemic theory suggests that HIV/AIDS can cooccur with other afflictions. As close to 20% of US adults live with a mental health condition, it is critical to understand the correlation between HIV risk behaviors and mental health needs, as well as protective factors such as social support in intervening the association between mental distress and HIV risk behaviors. Furthermore, as past research has shown mixed results concerning the function of social support on HIV risks by gender, it is important to conduct a gender-specific analysis.

METHODS

To assess the relationship between mental health needs, social support, and HIV risk behaviors, and to assess if social support can be a buffer, weakening the effect of mental health needs on HIV risk, in 2018, we analyzed representative, cross-sectional data from 2016 BRFSS collected from 33,705 individuals from four states in the United States, stratified by gender. Weighted logistic regression analyses, adjusted for age, race, marital status, education, and annual income, assessed the correlation between mental health needs, social support, and HIV risk behaviors. Furthermore, interaction analyses were performed to see if social support modifies the slope of mental health needs as a function of HIV risk behaviors.

RESULTS

For both genders, the odds of participating in HIV risk behaviors increase with mental health needs and decrease with the level of social support. Furthermore, social support mitigates the association between mental health needs and HIV risk behavior involvement for males, as males receiving high level of social support have least odds of HIV risk behaviors relative to males receiving low level of social support. Notably, for females, social support does not serve as a buffer against HIV risk behaviors when their mental health needs increase.

CONCLUSION

The study contributes to the knowledge base of HIV prevention and highlights the important role of mental health and social support against HIV risk behaviors when developing gender-specific prevention strategies.

Food insecurity, mental distress and suicidal ideation in rural Africa: Evidence from Nigeria, Uganda and Ghana

BACKGROUND

In sub-Saharan Africa, mental and substance-related disorders account for 19% of all years lived with disability, yet the intersection between poverty and mental distress is poorly understood since most psychiatric research is conducted in high-income countries.

AIMS

To examine the prevalence of and associations between food insecurity, mental distress and suicidal ideation in three rural village clusters in sub-Saharan Africa.

METHOD

Cross-sectional multivariate analysis of sociodemographic variables associated with mental distress and suicidal ideation in three countries. The sample included 1,142 individuals from three rural village clusters in Nigeria ( n = 380), Uganda ( n = 380) and Ghana ( n = 382). Food insecurity was measured based on the number of months in the previous year that the respondent's family reported being 'unable to eat two square meals per day'. Mental distress was assessed using the Kessler non-specific psychological distress scale (K6) and suicidal ideation was measured using an item from PRIME-MD. Other sociodemographic variables included gender, age, literacy and occupation.

RESULTS

The prevalence of individuals with moderate or severe mental distress in Nigeria, Uganda and Ghana were higher than previously reported in the literature: 35.5%, 30.8% and 30.4%, respectively, and suicidal ideation rates were 29.7%, 21.3% and 10.9%. No differences were observed in mental distress between men and women in any of the sites. Being a farmer (vs student or other) was protective for mental distress in two sites (Uganda and Ghana) but no other social indicators, such as age, gender, literacy and food insecurity, were significantly associated with mental distress. Risk for suicidal ideation differed across sites: it was associated with food insecurity in Nigeria, female gender in Uganda, and older age in Uganda.

CONCLUSIONS

Mental distress and suicidal ideation were highly prevalent in three settings of extreme poverty across all groups, in ways that were not always consistent with the global literature. These findings suggest that more research is needed in to better understand the social etiology of mental distress in sub-Saharan Africa.

Body and mind: retention in antiretroviral treatment care is improved by mental health training of care providers in Ethiopia

BACKGROUND

Ethiopia has achieved a high coverage of antiretroviral treatment (ART), but maintaining lifelong care is still a great challenge. Mental illnesses often co-exist with HIV/AIDS and may compromise the retention on ART. In order to improve prolonged retention in ART care, basic training in mental health care was introduced for ART providers, but this hasn't been evaluated yet. The aim of this study was to examine if this training has improved patient retention in care.

METHOD

A retrospective cohort study was employed to compare attrition from ART between clients attended by care provider trained with basic mental health service (exposed) and those in the standard ART follow-up care (unexposed) in public health facilities. A routine patient follow-up electronic database enrolled for ART between 2005 and 2017 was abstracted for the study. The Kaplan-Meier plot was used to compare the attrition rates between the two groups. The log-rank test was used to assess differences in the groups. The Cox proportional hazards regression model was used to determine predictors of attrition. We used estimated effect size of hazard ratios (HR) with 95% confidence intervals (CI).

RESULT

During the 12 years of observation, 8009 study participants under ART were followed for 33,498 person-years. The incidence of attrition was 6.5 per 100 person-years and 21% higher in the unexposed group (HR 1.21; 95% CI 1.1, 1.3), and retention in care was significantly higher in the mental health exposed group throughout the study period. WHO clinical staging III/IV, tuberculosis coinfection, the male gender, and poor functional status were independent risk factors for attrition.

CONCLUSION

We found that clients in the group exposed to mental health care training tended to have better retention in ART care with some variation according to gender, WHO Clinical stage and functional status. Training of ART providers in mental health may be considered in order to strengthen ART retention in low resource settings.

PLHIV are more likely to have mental distress: evidence from a comparison of a cross-section of HIV and diabetes patients at Tertiary Hospitals in Nigeria

HIV is now regarded as a chronic disease because of the availability of treatment. However, it is not well known if there are differences (clinically and in magnitude) between the mental health status of PLHIV and people living with other chronic diseases. The aim of this study was to compare the mental health status of patients attending antiretroviral clinics to patients attending diabetes clinics at tertiary hospitals in Ogun State, Nigeria. A comparative hospital-based cross-sectional study of mental distress among 639 HIV-positive and 639 diabetic patients was carried out. Multivariate logistic regression analysis was used to control for confounders and to predict the probability of mental distress in PLHIV. The mean age of the participants was 44.87 (± 13.83) years and it had a range of 63 years (17 to 80). The prevalence of mental distress was higher among HIV-positive participants (46.79%) than diabetic participants (33.02%) (p < 0.0001). HIV-positive participants had greater odds of mental distress than diabetics (odds ratio = 1.78; 95% CI = 1.41-2.25). HIV-positivity, female sex, lower levels of education, being unemployed, poorer housing conditions and separated, widowed or divorced were associated with higher odds of mental distress (p < 0.05). Mental distress was predicted by HIV-positivity, occupation and current marital status. HIV infection and social inequalities are independent risk factors for mental distress. The odds of having mental distress is higher among PLHIV compared with diabetic patients. Addressing social inequalities might be the critical factor in the control of mental distress among PLHIV.

Depression among female heads-of-household in rural Mozambique: A cross-sectional population-based survey

BACKGROUND

An estimated 350 million people live with depression worldwide. In Mozambique, there are no national data quantifying the burden of mental illnesses. With the sixth highest suicide rate in the world, there is strong evidence of an unmet mental health need. We conducted a survey to measure the prevalence of depression among female heads of household and assess individual, social, and cultural risk factors associated with a positive depression screening.

METHODS

This survey was conducted across 14 rural districts in central Mozambique in 2014. We gathered information from 3543 female heads of household (100% response rate) on > 500 variables, including a depression screening tool (PHQ-8). Weighted percentages of survey responses are reported.

RESULTS

Among female heads of household, 14% screened positive for depression (PHQ-8 score ≥ 10). Our adjusted models show increased odds of depression per additional year of age (aOR: 1.02 [1.01, 1.04]; p = 0.002), additional year of education (aOR: 1.06 [1.02, 1.11]; p = 0.006), and additional kilometer from the nearest clinic (aOR: 1.05 [1.02, 1.07]; p = < 0.001). Experiencing food insecurity (aOR: 1.05 [1.02, 1.08]; p = 0.003) was associated with increased odds of depression. Being single (aOR: 0.42 [0.29, 0.60]) or divorced/widowed/separated (aOR: 0.57 [0.34, 0.98]; p < 0.001) vs. married was protective against depression, as was a perceived "sufficient" household income (aOR: 0.37 [0.19, 0.69]; p = 0.008).

LIMITATIONS

Social desirability bias may have led women to underreport feelings of depression.

CONCLUSIONS

The association of more education and marriage with increased odds of depression may reflect a frustration with limited opportunity for success experienced by some women in rural Mozambique.

Mental distress and associated factors among undergraduate students at the University of Hargeisa, Somaliland: a cross-sectional study

Background

Mental distress is a common finding among University students. Empirical research has confirmed that the University student population has a higher prevalence of mental disorder than the general population. However, no previous study has examined the mental health conditions of students in Somaliland.

Methods

An institution based cross-sectional study was conducted on a sample of 570 undergraduate students at the University of Hargeisa in October, 2013. Study subjects were selected using a stratified random sampling. The Self-reporting questionnaire (SRQ-20) was used to assess mental distress. Multiple logistic regression analysis was carried out to identify factors independently associated with mental distress.

Results

The point prevalence of mental distress was found to be 19.8%. Mental distress was associated with being female (AOR = 3.52, 95% CI 1.94, 6.39), having a monthly income of 100 United States dollars (USD) or less (AOR = 2.19, 95% CI 1.12, 4.28), and not having a satisfying relationship with the family (AOR = 11.52, 95% CI 3.18, 41.72) and friends (AOR = 7.33, 95% CI 2.83, 18.93). Nearly one in five students (18.6%) has been using Khat in the previous 12 months. Khat use was also associated with greater likelihood of mental distress (AOR = 2.87, 95% CI 1.26, 6.56). In addition, financial difficulties and the poor prospect of finding a job were common sources of stress among the students.

Conclusions

A significant proportion of the students at the University of Hargeisa suffer from mental distress which might have a detrimental effect on their academic performance. The mental health needs of the University students require attention with special emphasis on female students, students experiencing financial hardships, students who use Khat and those who have interpersonal problems.

Determinants of common mental disorder, alcohol use disorder and cognitive morbidity among people coming for HIV testing in Goa, India

OBJECTIVE

To investigate associations between background characteristics (psychosocial adversity, risk behaviours/perception of risk and HIV-related knowledge, perceptions and beliefs) and psychological and cognitive morbidity among people coming for testing for HIV/AIDS in Goa, India.

METHODS

Analysis of cross-sectional baseline data (plus HIV status) from a prospective cohort study. Participants were recruited at the time of coming for HIV testing.

RESULTS

Consistent with associations found among general population samples, among our sample of 1934 participants, we found that indicators of psychosocial adversity were associated with CMD (common mental disorder - major depression, generalised anxiety and panic disorder) among people coming for testing for HIV. Similarly, perpetration of intimate partner violence was associated with AUD (alcohol use disorder). Two STI symptoms were associated with CMD, and sex with a non-primary partner was associated with AUD. Suboptimal knowledge about HIV transmission and prevention was associated with low cognitive test scores. In contrast with other studies, we found no evidence of any association between stigma and CMD. There was no evidence of modification of associations by HIV status.

CONCLUSIONS

Among people coming for testing for HIV/AIDS in Goa, India, we found that CMD occurred in the context of social and economic stressors (violence, symptoms of STI, poor education and food insecurity) and AUD was associated with violence and risky sexual behaviour. Further research is necessary to understand the role of gender, stigma and social norms in determining the relationship between sexual and mental health. Understanding associations between these background characteristics and psychological morbidity may help inform the design of appropriate early interventions for depression among people newly diagnosed HIV/AIDS.

Generalized psychological distress among HIV-infected patients enrolled in antiretroviral treatment in Dilla University Hospital, Gedeo zone, Ethiopia

BACKGROUND

Psychological disorders like depression and anxiety are potentially dangerous conditions. In the context of HIV/AIDS, this can influence health-seeking behavior or uptake of diagnosis and treatment for HIV/AIDS, add to the burden of disease for HIV patients, create difficulty in adherence to treatment, and increase the risk of mortality and morbidity. The objective of this study was to assess the prevalence and correlates of generalized psychological distress among HIV-infected subjects on antiretroviral treatment (ART).

DESIGN

An institution-based cross-sectional study was conducted. Interviews were conducted with 500 patients initiating ART at Dilla Referral Hospital. Generalized psychological distress was measured using the Hospital Anxiety and Depression Scale (HADS). A cutoff score ≥19 was used to identify possible cases of patients with generalized psychological distress. Multivariable logistic regression analysis using SPSS Version 20 was performed to identify factors associated with psychological distress.

RESULTS

The prevalence of generalized psychological distress among the population of this study was 11.2% (HADS≥19). Factors independently associated with generalized psychological distress were moderate stress (OR=6.87, 95% CI 2.27-20.81), low social support (OR=10.17, 95% CI 2.85-36.29), number of negative life events of six and above (OR=3.99, 95% CI 1.77-8.99), not disclosing HIV status (OR=5.24, 95% CI 1.33-20.62), and CD4 cell count of <200 cells/mm(3) (OR=1.98, 95% CI 0.45-0.83) and 200-499 cells/mm(3) (OR=3.53, 95% CI 1.62-7.73).

CONCLUSIONS

This study provides prevalence of psychological distress lower than the prevalence of common mental disorders in Ethiopia and comparable to some other studies in sub-Saharan Africa. The findings are important in terms of their relevance to identifying high-risk groups for generalized psychological distress and preventing distress through integrating mental health services with HIV/AIDS care and support program.

Frequency and correlates of anxiety and mood disorders among TB- and HIV-infected Zambians

We determined the frequency and correlates of current common mental disorders (CMDs) in a consecutive series of 649 adult patients with human immunodeficiency virus (HIV), tuberculosis (TB) or both receiving treatment at 16 primary health care centres across Zambia. Data on socio-demographic variables, clinical disease features, anxiety and mood disorders were collected. The frequency of any anxiety disorder (AD) was 30.8% and major depressive disorder (MDD) 11.3%. Although differences by disease group did not reach statistical significance, rates of suicidality (34.8%) and panic disorder (4.1%) were highest for the TB-HIV group (n = 269), while rates of generalised AD (13.3%), obsessive compulsive disorder (7.6%), posttraumatic stress disorder (7.4%) and any AD (37.8%) were highest for the HIV group (n = 149). Female gender (p = 0.004) predicted any current AD as well as current suicidality (p = 0.009), while lower education status (p < 0.001) predicted current MDD. World Health Organisation (WHO) clinical staging and antiretroviral treatment status were not significantly associated with MDD or anxiety in the HIV and co-infected groups. This study indicates the importance of early identification of CMDs in TB, HIV and co-infected patients, especially women and uneducated patients, newly initiated on treatment in primary care settings.

Depression and affective temperaments are associated with poor health-related quality of life in patients with HIV infection

INTRODUCTION

Human immunodeficiency virus (HIV) represents one of the most chronic and debilitating infections worldwide. Hopelessness and affective temperaments (mood that is characteristic of an individual's habitual functioning) may play important roles in the health-related quality of life (HRQoL) of patients with HIV. The purpose of this study was to examine affective temperaments in a sample of patients with HIV, the impact of hopelessness on HRQoL, and associations among HRQoL, hopelessness, and affective temperaments.

METHODS

The study involved 88 participants who were administered the short- form health survey (SF-36), the Beck hopelessness scale (BHS), the suicidal history self-rating screening scale (SHSS), the Gotland male depression scale (GMDS), and the temperament evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-A).

RESULTS

Patients with a poorer HRQoL reported more severe depression and hopelessness than patients with a higher HRQoL. Patients with a poorer HRQoL also had higher scores on all dimensions of the TEMPS-A with a depressive component compared to patients with a higher HRQoL. The small sample size in this study limits the generalizability of the findings.

CONCLUSION

Patients with a poorer HRQoL were more depressed and also at an increased risk of suicide as indicated by the more severe hopelessness they reported compared to patients with higher HRQoL. These patients were also more likely to have depressive affective temperaments than those with a higher HRQoL.

Health status and socio-economic factors associated with health facility utilization in rural and urban areas in Zambia

Abstracts

STRENGTHENING THE HEALTH SYSTEM TO ENHANCE MENTAL HEALTH IN ZAMBIA: A POLICY BRIEF

Background: Mental illness constitutes a large proportion of the burden of disease in Zambia. Yet mental health services at the primary care level are either provided in a fragmented manner or are lacking altogether.

Methods: A literature review focused on terms including mental health and primary care and strategic options were analyzed.

Results: From the analysis, two options were considered for integrating mental health into primary health care. An incremental option would start with a pilot project introducing mental health services into primary care with a well-designed evaluation before scaling up. One key advantage of this option is that it is possible to make improvements in the plan, if needed, before scaling up. A comprehensive option would entail introducing mental health services into primary care in all nine provinces of Zambia. In this option, scaling up could occur more rapidly than an incremental approach.

Conclusions: Strategies to implement either option must address several barriers, including insufficient funding for mental health services, inadequate mental health indicators, lack of general public awareness of and social stigma attached to mental illnesses and mental health care not being perceived as cost-effective or affordable.

The burden of knowing: balancing benefits and barriers in HIV testing decisions. a qualitative study from Zambia

Background

Client-initiated HIV counselling and testing has been scaled up in many African countries, in the form of voluntary counselling and testing (VCT). Test rates have remained low, with HIV-related stigma being an important barrier to HIV testing. This study explored HIV testing decisions in one rural and one urban district in Zambia with high HIV prevalence and available antiretroviral treatment.

Methods

Data were collected through 17 in-depth interviews and two focus group discussions with individuals and 10 in-depth interviews with counsellors. Interpretive description methodology was employed to analyse the data.

Results

'To know your status' was found to be a highly charged concept yielding strong barriers against HIV testing. VCT was perceived as a diagnostic device and a gateway to treatment for the severely ill. Known benefits of prevention and early treatment were outweighed by a perceived burden of knowing your HIV status related to stigma and fear. The manner in which the VCT services were organised added to this burden.

Conclusions

This study draws on social stigma theory to enhance the understanding of the continuity of HIV related stigma in the presence of ART, and argues that the burden of knowing an HIV status and the related reluctance to get HIV tested can be understood both as a form of label-avoidance and as strong expressions of the still powerful embodied memories of suffering and death among non-curable AIDS patients over the last decades. Hope lies in the emerging signs of a reduction in HIV related stigma experienced by those who had been tested for HIV. Further research into innovative HIV testing service designs that do not add to the burden of knowing is needed.

Validation of brief screening tools for depressive and alcohol use disorders among TB and HIV patients in primary care in Zambia

BACKGROUND

This study was conducted to evaluate the diagnostic accuracy and determine the optimum cut-off scores for clinical use of the Center for Epidemiological Studies Depression scale (CES-D) and Alcohol Use Disorders Identification Test (AUDIT) against a reference psychiatric diagnostic interview, in TB and anti-retroviral therapy (ART) patients in primary care in Zambia.

METHODS

This was a cross-sectional study in 16 primary level care clinics. Consecutive sampling was used to select 649 participants who started TB treatment or ART in the preceding month. Participants were first interviewed using the CES-D and AUDIT, and subsequently with a psychiatric diagnostic interview for current major depressive disorder (MDD) and alcohol use disorders (AUDs) using the Mini-International Neuropsychiatric Interview (MINI). The diagnostic accuracy was calculated using the Area Under the Receiver Operating Characteristic curve (AUROC). The optimum cut-off scores for clinical use were calculated using sensitivity and positive predictive value (PPV).

RESULTS

The CES-D and AUDIT had high internal consistency (Cronbach's alpha = 0.84; 0.98 respectively). Confirmatory factor analysis showed that the four-factor CES-D model was not a good fit for the data (Tucker-Lewis Fit Index (TLI) = 0.86; standardized root-mean square residual (SRMR) = 0.06) while the two-factor AUDIT model fitted the data well (TFI = 0.99; SRMR = 0.04). Both the CES-D and AUDIT demonstrated good discriminatory ability in detecting MINI-defined current MDDs and AUDs (AUROC for CES-D = 0.78; AUDIT = 0.98 for women and 0.75 for men). The optimum CES-D cut-off score in screening for current MDD was 22 (sensitivity 73%, PPV 76%) while that of the AUDIT in screening for AUD was 24 for women (sensitivity 60%, PPV 60%), and 20 for men (sensitivity 55%, PPV 50%).

CONCLUSIONS

The CES-D and AUDIT showed high discriminatory ability in measuring MINI-defined current MDD and AUD respectively. They are suitable mental health screening tools for use among TB and ART patients in primary care in Zambia.

Urogenital schistosomiasis in women of reproductive age in Tanzania's Lake Victoria region

We conducted a community-based study of 457 women aged 18-50 years living in eight rural villages in northwest Tanzania. The prevalence of female urogenital schistosomiasis (FUS) was 5% overall but ranged from 0% to 11%. FUS was associated with human immunodeficiency virus (HIV) infection (odds ratio [OR] = 4.0, 95% confidence interval [CI] = 1.2-13.5) and younger age (OR = 5.5 and 95% CI = 1.2-26.3 for ages < 25 years and OR = 8.2 and 95% CI = 1.7-38.4 for ages 25-29 years compared with age > 35 years). Overall HIV prevalence was 5.9% but was 17% among women with FUS. We observed significant geographical clustering of schistosomiasis: northern villages near Lake Victoria had more Schistosoma mansoni infections (P < 0.0001), and southern villages farther from the lake had more S. haematobium (P = 0.002). Our data support the postulate that FUS may be a risk factor for HIV infection and may contribute to the extremely high rates of HIV among young women in sub-Saharan Africa.

Poor mental health and sexual risk behaviours in Uganda: a cross-sectional population-based study

BACKGROUND

Poor mental health predicts sexual risk behaviours in high-income countries, but little is known about this association in low-income settings in sub-Saharan Africa where HIV is prevalent. This study investigated whether depression, psychological distress and alcohol use are associated with sexual risk behaviours in young Ugandan adults.

METHOD

Household sampling was performed in two Ugandan districts, with 646 men and women aged 18-30 years recruited. Hopkins Symptoms Checklist-25 was used to assess the presence of depression and psychological distress. Alcohol use was assessed using a question about self-reported heavy-episodic drinking. Information on sexual risk behaviour was obtained concerning number of lifetime sexual partners, ongoing concurrent sexual relationships and condom use.

RESULTS

Depression was associated with a greater number of lifetime partners and with having concurrent partners among women. Psychological distress was associated with a greater number of lifetime partners in both men and women and was marginally associated (p = 0.05) with having concurrent partners among women. Psychological distress was associated with inconsistent condom use among men. Alcohol use was associated with a greater number of lifetime partners and with having concurrent partners in both men and women, with particularly strong associations for both outcome measures found among women.

CONCLUSION

Poor mental health is associated with sexual risk behaviours in a low-income sub-Saharan African setting. HIV preventive interventions should consider including mental health and alcohol use reduction components into their intervention packages, in settings where depression, psychological distress and alcohol use are common.

Conceptual models for mental distress among HIV-infected and uninfected individuals: a contribution to clinical practice and research in primary-health-care centers in Zambia

Background

Mental distress is common in primary care and overrepresented among Human Immunodeficiency virus (HIV)-infected individuals, but access to effective treatment is limited, particularly in developing countries. Explanatory models (EM) are contextualised explanations of illnesses and treatments framed within a given society and are important in understanding an individual's perspective on the illness. Although individual variations are important in determining help-seeking and treatment behaviour patterns, the ability to cope with an illness and quality of life, the role of explanatory models in shaping treatment preferences is undervalued. The aim was to identify explanatory models employed by HIV-infected and uninfected individuals and to compare them with those employed by local health care providers. Furthermore, we aimed to build a theoretical model linking the perception of mental distress to treatment preferences and coping mechanisms.

Methods

Qualitative investigation nested in a cross-sectional validation study of 28 (male and female) attendees at four primary care clinics in Lusaka, Zambia, between December 2008 and May 2009. Consecutive clinic attendees were sampled on random days and conceptual models of mental distress were examined, using semi-structured interviews, in order to develop a taxonomic model in which each category was associated with a unique pattern of symptoms, treatment preferences and coping strategies.

Results

Mental distress was expressed primarily as somatic complaints including headaches, perturbed sleep and autonomic symptoms. Economic difficulties and interpersonal relationship problems were the most common causal models among uninfected individuals. Newly diagnosed HIV patients presented with a high degree of hopelessness and did not value seeking help for their symptoms. Patients not receiving anti-retroviral drugs (ARV) questioned their effectiveness and were equivocal about seeking help. Individuals receiving ARV were best adjusted to their status, expressed hope and valued counseling and support groups. Health care providers reported that 40% of mental distress cases were due to HIV infection.

Conclusions

Patient models concerning mental distress are critical to treatment-seeking decisions and coping mechanisms. Mental health interventions should be further researched and prioritized for HIV-infected individuals.

Depression and HIV in Botswana: a population-based study on gender-specific socioeconomic and behavioral correlates

Background

Depression is a leading contributor to the burden of disease worldwide, a critical barrier to HIV prevention and a common serious HIV co-morbidity. However, depression screening and treatment are limited in sub-Saharan Africa, and there are few population-level studies examining the prevalence and gender-specific factors associated with depression.

Methods

We conducted a cross-sectional population-based study of 18–49 year-old adults from five districts in Botswana with the highest prevalence of HIV-infection. We examined the prevalence of depressive symptoms, using a Hopkins Symptom Checklist for Depression (HSCL-D) score of ≥1.75 to define depression, and correlates of depression using multivariate logistic regression stratified by sex.

Results

Of 1,268 participants surveyed, 25.3% of women and 31.4% of men had depression. Among women, lower education (adjusted odds ratio [AOR] 2.07, 95% confidence interval [1.30–3.32]), higher income (1.77 [1.09–2.86]), and lack of control in sexual decision-making (2.35 [1.46–3.81]) were positively associated with depression. Among men, being single (1.95 [1.02–3.74]), living in a rural area (1.63 [1.02–2.65]), having frequent visits to a health provider (3.29 [1.88–5.74]), anticipated HIV stigma (fearing discrimination if HIV status was revealed) (2.04 [1.27–3.29]), and intergenerational sex (2.28 [1.17–4.41]) were independently associated with depression.

Discussion

Depression is highly prevalent in Botswana, and its correlates are gender-specific. Our findings suggest multiple targets for screening and prevention of depression and highlight the need to integrate mental health counseling and treatment into primary health care to decrease morbidity and improve HIV management efforts.

Multi-centred mixed-methods PEPFAR HIV care & support public health evaluation: study protocol

BACKGROUND

A public health response is essential to meet the multidimensional needs of patients and families affected by HIV disease in sub-Saharan Africa. In order to appraise current provision of HIV care and support in East Africa, and to provide evidence-based direction to future care programming, and Public Health Evaluation was commissioned by the PEPFAR programme of the US Government.

METHODS/DESIGN

This paper described the 2-Phase international mixed methods study protocol utilising longitudinal outcome measurement, surveys, patient and family qualitative interviews and focus groups, staff qualitative interviews, health economics and document analysis. Aim 1) To describe the nature and scope of HIV care and support in two African countries, including the types of facilities available, clients seen, and availability of specific components of care [Study Phase 1]. Aim 2) To determine patient health outcomes over time and principle cost drivers [Study Phase 2]. The study objectives are as follows. 1) To undertake a cross-sectional survey of service configuration and activity by sampling 10% of the facilities being funded by PEPFAR to provide HIV care and support in Kenya and Uganda (Phase 1) in order to describe care currently provided, including pharmacy drug reviews to determine availability and supply of essential drugs in HIV management. 2) To conduct patient focus group discussions at each of these (Phase 1) to determine care received. 3) To undertake a longitudinal prospective study of 1200 patients who are newly diagnosed with HIV or patients with HIV who present with a new problem attending PEPFAR care and support services. Data collection includes self-reported quality of life, core palliative outcomes and components of care received (Phase 2). 4) To conduct qualitative interviews with staff, patients and carers in order to explore and understand service issues and care provision in more depth (Phase 2). 5) To undertake document analysis to appraise the clinical care procedures at each facility (Phase 2). 6) To determine principle cost drivers including staff, overhead and laboratory costs (Phase 2).

DISCUSSION

This novel mixed methods protocol will permit transparent presentation of subsequent dataset results publication, and offers a substantive model of protocol design to measure and integrate key activities and outcomes that underpin a public health approach to disease management in a low-income setting.

Indicators of Adherence to Antiretroviral Therapy Treatment Among HIV/AIDS Patients in 5 African Countries

As the HIV epidemic threatens the social fabric of countries struggling with HIV prevalence rates as high as 10% to 30%, access to antiretroviral therapy (ART) alone is only the beginning of the clinical challenge. There is a need to identify adherence indicators that will ensure long-term treatment success. A cross-sectional review of 921 adult patients on ART for at least 1 year was conducted. Through an administered adherence survey, key indicators were found to be highly correlated with patient adherence. The adherence rate in this sample was 72% after being on treatment for an average of 15 months. This data suggest that having a high perceived quality of care and owning one’s own home positively affected patients’ adherence. Indicators such as alcohol use in the last month and a high level of depression negatively affected patients’ adherence. Targeting specific indicators for specific interventions will guard against nonadherence, leading to treatment failure.

Comparative validity of screening instruments for mental distress in zambia

Background:

The recognition of mental health as a major contributor to the global burden of disease has led to an increase in the demand for the inclusion of mental health services in primary health care as well as in community-based health surveys in order to improve screening, diagnosis and treatment of mental distress. Many screening instruments are now available. However, the cultural validity of these instruments to detect mental distress has rarely been investigated in developing countries. In these countries, limited trained staff and specialized psychiatric facilities hamper improvement of mental health services. It is therefore imperative to develop a quick, low cost screening instrument that does not require specialized training. We validated different well established screening instruments among primary health care clinic attendees in Lusaka, Zambia. We also assess the face, content and criterion validity of the SRQ’s and determined the most commonly reported symptoms for mental distress.

Methods:

The screening instruments, SRQ-20, SRQ-10 and GHQ-12 were used as concurrent criteria for each other and compared against a gold standard, DSM-IV. Their correlation, sensitivity and specificity were assessed. All instruments were administered to 400 primary health care clinic attendees. In-depth interviews were also conducted with 28 of these clinic attendees.

Results:

Both the SRQ-20 and SRQ-10 had high properties for identifying mental distress correctly with an AUC of 0.96 and 0.95 respectively while the GHQ-12 had modest properties (AUC, 0.81). The optimum cut-off points for this population were 7 and 3 for the SRQ and GHQ-12 respectively. The SRQ was also found to have good face and content validity.

Conclusion:

The study establishes the utility of the SRQ-20 for detecting mental distress cases and also underscores the importance of validating instruments to suit the context of the target population. It also validates the SRQ-10 as the first reliable abbreviated and easy-to-use screening instrument for mental distress in primary health care facilities in Zambia.
