Prevalence of psychological distress and associated factors in tuberculosis patients in public primary care clinics in South Africa

BackgroundPsychological distress has been rarely investigated among tuberculosis patients in low-resource settings despite the fact that mental ill health has far-reaching consequences for the health outcome of tuberculosis (TB) patients. In this study, we assessed the prevalence and predictors of psychological distress as a proxy for common mental disorders among tuberculosis (TB) patients in South Africa, where over 60 % of the TB patients are co-infected with HIV.MethodsWe interviewed 4900 tuberculosis public primary care patients within one month of initiation of anti-tuberculosis treatment for the presence of psychological distress using the Kessler-10 item scale (K-10), and identified predictors of distress using multiple logistic regressions. The Kessler scale contains items associated with anxiety and depression. Data on socio-demographic variables, health status, alcohol and tobacco use and adherence to anti-TB drugs and anti-retroviral therapy (ART) were collected using a structured questionnaire.ResultsUsing a cut off score of ≥28 and ≥16 on the K-10, 32.9 % and 81 % of tuberculosis patients had symptoms of distress, respectively. In multivariable analysis older age (OR = 1.52; 95 % CI = 1.24-1.85), lower formal education (OR = 0.77; 95 % CI = 0.65-0.91), poverty (OR = 1.90; 95 % CI = 1.57-2.31) and not married, separated, divorced or widowed (OR = 0.74; 95 % CI = 0.62-0.87) were associated with psychological distress (K-10 ≥28), and older age (OR = 1.30; 95 % CI = 1.00-1.69), lower formal education (OR = 0.55; 95 % CI = 0.42-0.71), poverty (OR = 2.02; 95 % CI = 1.50-2.70) and being HIV positive (OR = 1.44; 95 % CI = 1.19-1.74) were associated with psychological distress (K-10 ≥16). In the final model mental illness co-morbidity (hazardous or harmful alcohol use) and non-adherence to anti-TB medication and/or antiretroviral therapy were not associated with psychological distress.ConclusionsThe study found high rates of psychological distress among tuberculosis patients. Improved training of providers in screening for psychological distress, appropriate referral to relevant health practitioners and providing comprehensive treatment for patients with TB who are co-infected with HIV is essential to improve their health outcomes. It is also important that structural interventions are promoted in order to improve the financial status of this group of patients.

Predictors of tuberculosis (TB) and antiretroviral (ARV) medication non-adherence in public primary care patients in South Africa: a cross sectional study

BackgroundDespite the downward trend in the absolute number of tuberculosis (TB) cases since 2006 and the fall in the incidence rates since 2001, the burden of disease caused by TB remains a global health challenge. The co-infection between TB and HIV adds to this disease burden. TB is completely curable through the intake of a strict anti-TB drug treatment regimen which requires an extremely high and consistent level of adherence.The aim of this study was to investigate factors associated with adherence to anti-TB and HIV treatment drugs.MethodsA cross-sectional survey method was used. Three study districts (14 primary health care facilities in each) were selected on the basis of the highest TB caseload per clinic. All new TB and new TB retreatment patients were consecutively screened within one month of anti-tuberculosis treatment. The sample comprised of 3107 TB patients who had been on treatment for at least three weeks and a sub-sample of the total sample were on both anti-TB treatment and anti-retro-viral therapy(ART) (N = 757). Data collection tools included: a Socio-Demographic Questionnaire; a Post-Traumatic-Stress-Disorder (PTSD) Screen; a Psychological Distress Scale; the Alcohol Use Disorder Identification Test (AUDIT); and self-report measures of tobacco use, perceived health status and adherence to anti-TB drugs and ART.ResultsThe majority of the participants (N = 3107) were new TB cases with a 55.9% HIV co-infection rate in this adult male and female sample 18 years and older. Significant predictors of non-adherence common to both anti-TB drugs and to dual therapy (ART and anti-TB drugs) included poverty, having one or more co-morbid health condition, being a high risk for alcohol mis-use and a partner who is HIV positive. An additional predictor for non-adherence to anti-TB drugs was tobacco use.ConclusionsA comprehensive treatment programme addressing poverty, alcohol mis-use, tobacco use and psycho-social counseling is indicated for TB patients (with and without HIV). The treatment care package needs to involve not only the health sector but other relevant government sectors, such as social development.

Screening and brief interventions for hazardous and harmful alcohol use among patients with active tuberculosis attending primary public care clinics in South Africa: results from a cluster randomized controlled trial

BackgroundIn 2008 the World Health Organization (WHO) reported that South Africa had the highest tuberculosis (TB) incidence in the world. This high incidence rate is linked to a number of factors, including HIV co-infection and alcohol use disorders. The diagnosis and treatment package for TB and HIV co-infection is relatively well established in South Africa. However, because alcohol use disorders may present more insidiously, making it difficult to diagnose, those patients with active TB and misusing alcohol are not easily cured from TB. With this in mind, the primary purpose of this cluster randomized controlled trial was to provide screening for alcohol misuse and to test the effectiveness of brief interventions in reducing alcohol intake in those patients with active TB found to be misusing alcohol in primary public health care clinics in three districts in South Africa.MethodsWithin each of the three provinces targeted, one district with the highest TB burden was selected. Furthermore, 14 primary health care facilities with the highest TB caseload in each district were selected. In each district, 7 of the 14 (50%) clinics were randomly assigned to a control arm and another 7 of the 14 (50%) clinics assigned to intervention arm. At the clinic level systematic sampling was used to recruit newly diagnosed and retreatment TB patients. Those consenting were screened for alcohol misuse using the Alcohol Use Disorder Identification Test (AUDIT). Patients who screened positive for alcohol misuse over a 6-month period were given either a brief intervention based on the Information-Motivation-Behavioural Skills (IMB) Model or an alcohol use health education leaflet.ResultsOf the 4882 tuberculosis patients screened for alcohol and agreed to participate in the trial, 1196 (24.6%) tested positive for the AUDIT. Among the 853 (71%) patients who also attended the 6-month follow-up session, the frequency of positive screening results at baseline/follow-up were 100/21.2% for the AUDIT (P < 0.001) for the control group and 100/16.8% (P < 0.001) for the intervention group. The intervention effect on the AUDIT score was statistically not significant. The intervention effect was also not significant for hazardous or harmful drinkers and alcohol dependent drinkers (AUDIT: 7–40), alcohol dependent drinkers and heavy episodic drinking, while the control group effect was significant for hazardous drinkers (AUDIT: 7–19) (P = 0.035).ConclusionThe results suggest that alcohol screening and the provision of a health education leaflet on sensible drinking performed at the beginning of anti-tuberculosis treatment in public primary care settings may be effective in reducing alcohol consumption.Trial registrationsPACTR201105000297151

Quality of life among tuberculosis (TB), TB retreatment and/or TB-HIV co-infected primary public health care patients in three districts in South Africa

IntroductionTB and HIV co-morbidity amount to a massive burden on healthcare systems in many countries. This study investigates health related quality of life among tuberculosis (TB), TB retreatment and TB-HIV co-infected public primary health care patients in three districts in South Africa.MethodsA cross sectional study was conducted among 4900 TB patients who were in the first month of anti-TB treatment in primary public health care clinics in three districts in South Africa. Quality of life was assessed using the social functioning (SF)-12 Health Survey through face to face interviews. Associations of physical health (Physical health Component Summary = PCS) and mental health (Mental health Component Summary = MCS) were identified using logistic regression analyses.ResultsThe overall physical and mental health scores were 42.5 and 40.7, respectively. Emotional role, general health and bodily pain had the lowest sub-scale scores, while energy and fatigue and mental health had the highest domain scores. Independent Kruskal–Wallis tests found significant positive effects of being TB-HIV co-infected on the domains of mental health functioning, emotional role, energy and fatigue, social function and physical role, while significant negative effects were observed on general health, bodily pain and physical function. In multivariable analysis higher educational, lower psychological distress, having fewer chronic conditions and being HIV negative were significantly positively associated with PCS, and low poverty, low psychological distress and being HIV positive were positively significantly associated with MCS.ConclusionTB and HIV weaken patients’ physical functioning and impair their quality of life. It is imperative that TB control programmes at public health clinics design strategies to improve the quality of health of TB and HIV co-infected patients.

Hazardous and harmful alcohol use and associated factors in tuberculosis public primary care patients in South Africa.

The aim of this study was to assess the prevalence of hazardous and harmful alcohol use and associated factors among patients with tuberculosis in South Africa. In a cross-sectional survey new tuberculosis (TB) and TB retreatment patients were consecutively screened using the Alcohol Use Disorder Identification Test (AUDIT) within one month of anti-tuberculosis treatment. The sample included 4,900 (54.5% men and women 45.5%) tuberculosis patients from 42 primary care clinics in three districts. Results indicate that, overall 23.2% of the patients were hazardous or harmful alcohol drinkers, 31.8% of men and 13.0% of women were found to be hazardous drinkers, and 9.3% of men and 3.4% of women meet criteria for probable alcohol dependence (harmful drinking) as defined by the AUDIT. Men had significantly higher AUDIT scores than women. In multivariable analyses it was found that among men poor perceived health status, tobacco use, psychological distress, being a TB retreatment patient and not being on antiretroviral therapy (ART), and among women lower education, tobacco use and being a TB retreatment patient were associated with hazardous or harmful alcohol use. The study found a high prevalence of hazardous or harmful alcohol use among tuberculosis primary care patients. This calls for screening and brief intervention and a comprehensive alcohol treatment programme as a key component of TB management in South Africa.

Prevalence of post-traumatic stress symptoms and associated factors in tuberculosis (TB), TB retreatment and/or TB–HIV co-infected primary public health-care patients in three districts in South Africa

High rates of tuberculosis (TB) and TB/HIV co-infection is often linked with mental health issues such as post-traumatic stress disorder (PTSD) symptoms, which is further associated with poor health outcomes. In a country such as South Africa where rates of these infectious diseases are high, it is concerning that there is limited/no data on prevalence rates of mental disorders such as PTSD and its associated factors. Therefore, the aim of this study was to establish the prevalence of PTSD symptoms and associated factors in TB, TB retreatment and/or TB–HIV co-infected primary public health-care patients in three districts in South Africa. Brief screening self-report tools were used to measure: PTSD symptoms, psychological distress (anxiety and depression) and alcohol misuse. Other relevant measures, such as adherence to medication, stressful life events and sexual risk-taking behaviours, were obtained through structured questions. A total of 4900 public primary care adult patients from clinics in high TB burden districts from three provinces in South Africa participated. All the patients screened positive for TB (either new or retreatment cases). The prevalence of PTSD symptoms was 29.6%. Patients who screened positive for PTSD symptoms and psychological distress were more likely to be on antidepressant medication. Factors that predicted PTSD symptoms were poverty, residing in an urban area, psychological distress, suicide attempt, alcohol and/or drug use before sex, unprotected sex, TB–HIV co-infected and the number of other chronic conditions. Health-care systems should be strengthened to improve delivery of mental health care, by focusing on existing programmes and activities, such as those which address the prevention and treatment of TB and HIV.

Social and structural factors associated with vulnerability to HIV infection among young adults in South Africa

There is increasing focus on social and structural factors following the marginal success of individual-level strategies for HIV prevention. While there is evidence of decreased HIV prevalence among young individuals in South Africa, there is still a need to monitor HIV incidence and prevalence in this vulnerable group as well as track and prevent high-risk sexual behavior(s). This study investigated the social and structural factors that shape the context of vulnerability to increased risk of exposure to HIV infection. A mixed-methods approach including qualitative and quantitative design components was employed. Young adults in the age group 18–24 were interviewed from four provinces in South Africa. The qualitative results produced strong support for the effectiveness of loveLife’s HIV prevention programs. The household-based survey results showed that the strongest predictors of self-reported HIV infection (indicating a greater chance of being infected) using adjusted odds ratios (aOR) are: being diagnosed with an STI in a lifetime (aOR 13.68 95% Confidence Interval (CI) [4.61–40.56]; p < .001), inconsistent condom use (aOR 6.27 95% CI [2.08–18.84]; p < .01), and difficulty in accessing condoms (aOR 2.86 95% CI [1.04–7.88]; p < .05). The strongest predictors that indicated a decreased chance of being infected with the HI virus are: talking with partner about condom use in the past 12 months (aOR .08 95% CI [.02–.36]; p < .001) and having a grade 8 (aOR .04 95% CI [.01–.66]; p < .05) and higher educational level (aOR .04 95% CI [.01–.43]). These results show that social and structural factors serve as risk and protective factors for HIV prevention among young people. Intervention programs need to continue to focus on effective communication strategies and healthy relationships. Structural adjustments have to be made to encourage school attendance. Finally, social/health policies and health service delivery have to also be refined so that young people have access to youth friendly health services.

Inconsistent condom use among public primary care patients with tuberculosis in South Africa.

The high rate of HIV infections among tuberculosis (TB) patients in South Africa calls for urgent HIV reduction interventions in this subpopulation. While correct and consistent condom use is one of the effective means of HIV prevention among sexually active people, there is insufficient research on condom use among TB patients in South Africa. The aim of this paper was to determine the prevalence of inconsistent condom use among public primary care TB patients and its associated factors using a sample of 4900 TB patients from a cross-sectional survey in three health districts in South Africa. Results indicated that when asked about their consistency of condom use in the past 3 months, 63.5% of the participants reported that they did not always use condoms. In the multivariable analysis, being married (OR = 1.66; 95% CI 1.25–2.20) or cohabitating or separated, divorced, or widowed (OR = 3.67; 1.85–7.29), lower educational level (OR = 0.66; 0.46–0.94), greater poverty (OR = 1.60; 1.25–2.20), not having HIV status disclosed (OR = 0.34; 0.25–0.48), sexual partner on antiretroviral treatment (OR = 0.38; 0.23–0.60), and partner alcohol use before sex (OR = 1.56; 1.30–1.90) were significantly associated with inconsistent condom use in the past 3 months. The low proportion of consistent condom use among TB patients needs to be improved.

A community-based study to examine the effect of a youth HIV prevention programme in South Africa.

The aim of this study was to examine the relationships among changes in self-reported HIV and sexually transmitted infection (STI) and exposure to the loveLife youth HIV prevention programmes. A cross-sectional population-based household survey was conducted using a multistage stratified cluster sampling approach. The total sample included 3123 participants, aged 18–24, 54.6% men and 45.4% women, from four provinces (Eastern Cape, Gauteng, KwaZulu-Natal and Mpumalanga). Results indicate a self-reported STI past-year prevalence of 2.6%, experienced genital sores or ulcers in the past year prevalence of 3.9% and an HIV self-reported prevalence of 7.4%. In multivariable analyses it was found that knowing a person living with HIV and a person who has died from AIDS, lower education, having had two or more sexual partners in the past year, not having talked with a partner about condom use, difficulty of getting condoms and not having been male circumcised were associated with having been diagnosed with an STI in the past 12 months and/or HIV. Face-to-face and multimedia youth HIV prevention programmes had limited effect.

How Later Adolescents With Adult Responsibilities Experience HIV Bereavement in Nigeria: Application of a Bereavement Model

&NA; Conceptual models assist in the better understanding of phenomena and also in the planning of effective responses. We applied the Dual Process Model (DPM) to examine how six later adolescents (ages 18‐24 years) experienced the multiple stressors of bereavement, maturational tasks, and caregiving roles. Using a semi‐structured interviewing approach, participants who were purposively recruited narrated how parental loss to HIV impacted their lives. In relation to the proposition of the DPM model, the study revealed that participants (a) anticipated grief before the death of their parents, (b) engaged in activities to return to normalcy after parental loss, and (c) neglected grief emotions in order to cope with the demands of caregiving. The application of a model to examine responses to bereavement can assist health care practitioners to appreciate and have a deeper understanding of how best to approach caring interventions for late adolescents with multiple stressors.
