Clinical characteristics of people presenting with first episode psychosis pre- and during the COVID-19 pandemic in KwaZulu-Natal Province, South Africa.

BACKGROUND: The COVID-19 pandemic and the lockdown experience may have not only precipitated or exacerbated mental illness but also influenced access to care and the nature and content of the psychotic symptomatology of people with psychosis. AIM: This study aimed to evaluate the association of the COVID-19 pandemic and lockdown experience on clinical presentation and quality of life of people (QOL) with first episode psychosis (FEP). METHOD: Two first episode psychosis cohorts from the same epidemiological area collected prior to, and during the COVID-19 pandemic and lockdown were compared in terms of clinical symptomatology, substance use and QOL. All adult in- and outpatients with FEP at five clinical units in KwaZulu-Natal, South Africa, aged between 18 and 45 years, were assessed with the MINI interview for psychosis, Positive and Negative Symptoms Scale, WHO Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) and the WHO QOL scales. RESULTS: Eighty-eight FEP participants were recruited between 2019 and 2020 (cohort 1) before the pandemic. Study recruitment was suspended in March 2020 due to the pandemic. On study resumption from November 2020 to November 2022, 95 new participants (cohort 2) were recruited. There were no sociodemographic differences between the two cohorts, except unemployment status (57% vs. 65%) and household income. The cohort presenting post-COVID-19 pandemic onset had significantly more positive psychotic symptoms (21.9 vs. 23.7), lower PANSS domain depressive score, more lifetime use of tobacco, cannabis and alcohol. However, they reported improved QOL (196 vs. 239). CONCLUSION: Following the pandemic and lockdown experience participants presented with more severe psychotic symptoms and concomitant substance use but improved perceived QOL. This suggests the need to explore individual and social factors that may influence the clinical presentation.

Water, sanitation and depression in rural communities: evidence from nationally representative study data in South Africa.

Clean water and sanitation provisions are essential for good hygiene and health, with rural South Africa facing a simultaneous access crisis of both, the direct health effect of restricted access to both on mental health remaining scarce and largely overlooked. This study investigated the association between access to clean water and sanitation on depression in rural South Africa utilizing the most recent data (year 2017) from the South African National Income Dynamics Study. Our study outcome was depression, based on the 10-item abridged version of the Center for Epidemiologic Studies Depression Scale (data available in SA-NIDS), the main exposures being access to clean water and adequate sanitation facilities (i.e. flushing toilets). Two types of analyses were conducted: first, adjusted logistic regression models were fitted to assess the relationship between lack of access to clean water and adequate sanitation to depression. Second, we conducted mediation analysis to investigate whether access to clean water mediated the relationship between lack of access to toilets and depression. A high proportion of rural participants lacked access to clean water (n = 6,188, 47.6%) and adequate toilets (n = 9,797, 81.6%). The regression analyses indicated that lack of access to both clean water (OR = 1.21, 95% CI: 1.06-1.39) and adequate sanitation (OR = 1.36, 95% CI: 1.10-1.69) were significantly associated with greater odds of depression. The mediation analysis indicated that access to clean water partially mediated the relationship between lack of access to adequate sanitation and depression, the total mediated effect being 18.2% (95% CI: 11.0%-51.0%). Most rural communities in South Africa lack access to basic services that are essential for human dignity and a decent quality of life, leading to opportunities for poor mental health, with its various consequences for socio-economic development and personal wellbeing, including avoidable depression.

Developing and testing unconditional cash transfer strategies among young adults with first-episode psychosis in South Africa: a study protocol for a pilot randomised control trial (PRS-FEP trial).

INTRODUCTION: Access to mental health services is a challenge, especially for young people who are over-represented in the unemployment and poverty index in South Africa. Therefore, continuing care is a problem after hospital discharge for young people with first-episode psychosis (FEP) due to a lack of clinical engagement and follow-up, for which they need support, including financial, to improve their outcomes. This pilot randomised control trial (RCT) aims to assess the feasibility and acceptability of financial support, in the form of an unconditional cash transfer (UCT), among young patients with FEP to prevent relapse. METHODS AND ANALYSIS: This study will use a 1:1 ratio two-arm open-label pilot RCT of 60 young participants (18-29 years) with FEP in remission, who will be recruited from specialised psychiatric facilities in KwaZulu-Natal Province, South Africa. This study will implement an UCT and assess its feasibility, acceptability and preliminary clinical outcomes (ie, medication adherence, relapse, quality of life, personal and social function). The follow-up time will be 3 months, the outcomes being measured at baseline, months 1 and 3. Descriptive and conventional content analysis will be done for quantitative and qualitative data, respectively. ETHICS AND DISSEMINATION: The study obtained provisional approval from the Biomedical Research Ethics Committee at the University of KwaZulu-Natal(#BREC/00004117/2022). Also is registered on the South African National clinical trial registry (#DOH-27-092022-5894) and approved by the KwaZulu-Natal department of health (#NHRD Ref: KZ_2002209_033). The results from this investigation will be actively disseminated through peer-reviewed journal publications, conference presentations and stakeholder engagement. TRIAL REGISTRATION NUMBER: DOH-27-092022-5894.

Course of psychotic experiences and disorders among apprentice traditional health practitioners in rural South Africa: 3-year follow-up study.

Background: Culture is inevitably linked with the experience, interpretation and course of what modern biomedicine understands to be psychotic symptoms. However, data on psychoses in low- and middle-income countries are sparse. Our previous study showed that psychotic and mood-related experiences, symptoms and disorders are common among individuals who had received the ancestral calling to become a traditional health practitioner (THP) in rural KwaZulu-Natal, South Africa. Our related ethnographic study suggested that ukuthwasa (the training to become a THP) may positively moderate these calling-related symptoms. As far as we know, no research has been conducted into the course of psychiatric symptoms among apprentice THPs. Objective: We studied the course of psychotic experiences, symptoms and disorders among apprentice THPs. We also assessed their level of functioning and expanded our knowledge on ukuthwasa. Materials and methods: We performed a 3-year follow-up of a baseline sample of apprentice THPs (n = 48). Psychiatric assessments (CAPE, SCAN), assessment of functioning (WHODAS) and a semi-structured qualitative questionnaire were completed for 42 individuals. Results: At 3-year follow-up, psychotic experiences were associated with significantly less distress and there was a reduction in frequency of psychotic symptoms compared to baseline. The number of participants with psychotic disorders had decreased from 7 (17%) to 4 (10%). Six out of seven participants (86%) with a psychotic disorder at baseline no longer had a psychiatric diagnosis at follow-up. Although the mean level of disability among the (apprentice) THPs corresponded with the 78th percentile found in the general population, 37 participants (88%) reported no or mild disability. Forty-one participants (98%) reported that ukuthwasa had positively influenced their psychiatric symptoms. Conclusion: In rural KwaZulu-Natal, psychotic experiences, symptoms and disorders have a benign course in most individuals who are undergoing the process of becoming a THP. Ukuthwasa may be an effective, culturally sanctioned, healing intervention for some selected individuals, potentially because it reframes distressing experiences into positive and highly valued experiences, reduces stigma, and enhances social empowerment and identity construction. This implies that cultural and spiritual interventions can have a positive influence on the course of psychosis.

Community disaster exposure and first onset of depression: A panel analysis of nationally representative South African data, 2008-2017.

Sub-Saharan Africa faces unprecedented disasters, with climate change expected to exacerbate the frequency and severity of unpredictable and stressful catastrophic events. Unlike developed nations, reconstruction in developing nations is hindered by resource constraints, with certain communities potentially experiencing multiple and enduring effects of disasters. Despite the potential danger of such cumulative community disaster exposure on mental health (e.g. depression), large-scale population-level evidence for the region is limited. We investigated the association between exposure to cumulative disaster and the first onset of depression in a nationally representative survey in South Africa. We used panel data from the South African National Income Dynamics Study (SA-NIDS) from 2008-2017, consisting of 17,255 adult study participants who were depression free at baseline. Risk of first depression onset between individuals exposed and unexposed to community disaster was measured, accounting for multiple disaster exposure over time by fitting generalized estimating equation (GEE) regression models. Data on the geographic location of disasters were obtained from the South African government gazette, and mapped with the government delineated SA-NIDS households' locations. Of the sampled individuals, 2,986 were exposed to disaster during the study duration (17.3%). Increased cumulative community disaster was significantly associated with the likelihood of depression onset (adjusted relative risk [aRR] = 1.20, p<0.01, 95% CI: 1.09-1.33), even after controlling for socio-demographic factors. In sub-group analyses, greater likelihood of depression onset was found among females [but not in men] (aRR = 1.23, p<0.01, 95% CI: 1.09-1.38), Black African [but not in other population group] (aRR = 1.21, p<0.01, 95% CI: 1.09-1.36), lower education attainment group [but not in tertiary and above educational attainment group] (aRR = 1.20, p<0.01, 95% CI: 1.08-1.33), and lower income attainment group [but not in the top income quartile group] (aRR = 1.24, p<0.01, 95% CI: 1.11-1.38), due to cumulative community disaster. Although cumulative community disaster exposure was significantly associated with the first onset of depression, its negative impact may be more pronounced among individuals considered chronically socially vulnerable (i.e. the groups above) in South Africa. Given that many individuals in South Africa rely on social, food parcel relief, and health services from government/public sector, timely access to community-based supportive intervention is needed for disaster survivors, prioritizing socially vulnerable groups to help mitigate problems associated with mental health challenges.

Ancestral calling, traditional health practitioner training and mental illness: An ethnographic study from rural KwaZulu-Natal, South Africa.

This qualitative ethnographic study complements an epidemiological study on first episode psychosis in Vulindlela, a rural area in KwaZulu-Natal, South Africa. It focuses on two themes that emerged from our data: (1) the calling of the ancestors to become a traditional health practitioner and (2) ukuthwasa, the training to become a traditional health practitioner. The purpose of this study is to describe the ancestral calling, and to explore whether ukuthwasa may help with the management of mental disturbances, including unusual perceptual experiences. We also provide a discussion of the changing sociopolitical context of healing in KwaZulu-Natal, as a background to our study. In-depth interviews were conducted with 20 (apprentice) traditional health practitioners, formal health practitioners, patients and relatives recruited through local traditional health practitioners and a health care clinic. Our results show that the ancestral calling might announce itself with symptoms of mental illness including unusual perceptual experiences, for which some participants consider ukuthwasa as the only effective cure. We found indications that in some individuals successful completion of ukuthwasa might promote recovery from their illness and lead to a profession in which the unusual perceptual experiences become a legitimate and positively valued aspect. We suggest that - in this particular community today, which has been subject to several sociopolitical changes - ukuthwasa may be a culturally sanctioned healing process which moderates experiences that a Western psychiatric system might characterize as psychotic symptoms, providing some individuals with a lucrative and respected role in society.

Psychopathology among apprentice traditional health practitioners: A quantitative study from rural KwaZulu-Natal, South Africa.

Sociocultural context seems to influence the epidemiology, phenotype, treatment, and course of psychosis. However, data from low- and middle-income countries is sparse. This research is part of a multidisciplinary and multimethod study on possible mental disturbances, including hallucinations, among (apprentice) traditional health practitioners (THPs) who have experienced the "ancestral calling to become a THP" in rural KwaZulu-Natal, South Africa. The aim of the current article is to examine whether the calling-related experiences can be assessed according to a psychiatric taxonomy. We included individuals who were identified with the calling and who were undergoing training to become a THP (ukuthwasa). IsiZulu-speaking formal mental health practitioners conducted thorough psychiatric interviews that measured psychological experiences with and without distress using the Community Assessment of Psychic Experiences, and psychiatric symptoms and disorders using the Schedule for Clinical Assessment in Neuropsychiatry. Of the 48 individuals who participated, 92% had psychotic experiences (PE), causing distress in 75%; and 23% met DSM-5 criteria for an unspecified psychotic disorder (15%) or mood disorder (8%). In conclusion, in rural KwaZulu-Natal, the ancestral calling may resemble phenomena that psychiatry would understand in the context of psychosis, ranging from subclinical PE to clinical psychotic disorder. Ukuthwasa might have a beneficial influence on the course of psychotic symptoms in some individuals, potentially because it reduces stigma and promotes recovery. Further multidisciplinary research is needed to investigate the psychopathology of the apprentice THPs and the underlying processes of ukuthwasa.

Spatial clustering of food insecurity and its association with depression: a geospatial analysis of nationally representative South African data, 2008-2015.

While food insecurity is a persistent public health challenge, its long-term association with depression at a national level is unknown. We investigated the spatial heterogeneity of food insecurity and its association with depression in South Africa (SA), using nationally-representative panel data from the South African National Income Dynamics Study (years 2008-2015). Geographical clusters ("hotpots") of food insecurity were identified using Kulldorff spatial scan statistic in SaTScan. Regression models were fitted to assess association between residing in food insecure hotspot communities and depression. Surprisingly, we found food insecurity hotspots (p < 0.001) in high-suitability agricultural crop and livestock production areas with reliable rainfall and fertile soils. At baseline (N = 15,630), we found greater likelihood of depression in individuals residing in food insecure hotspot communities [adjusted relative risk (aRR) = 1.13, 95% CI:1.01-1.27] using a generalized linear regression model. When the panel analysis was limited to 8,801 participants who were depression free at baseline, residing in a food insecure hotspot community was significantly associated with higher subsequent incidence of depression (aRR = 1.11, 95% CI:1.01-1.22) using a generalized estimating equation regression model. The association persisted even after controlling for multiple socioeconomic factors and household food insecurity. We identified spatial heterogeneity of food insecurity at a national scale in SA, with a demonstrated greater risk of incident depression in hotspots. More importantly, our finding points to the "Food Security Paradox", food insecurity in areas with high food-producing potential. There is a need for place-based policy interventions that target communities vulnerable to food insecurity, to reduce the burden of depression.

Major Depression and Stigma among Individuals with Multidrug-Resistant Tuberculosis in South Africa.

Stigma is an important social determinant of health-seeking behavior; however, the nature and extent of its association with depression among people living with multidrug-resistant tuberculosis (MDR-TB) are not well-understood. We enrolled 200 microbiologically confirmed MDR-TB inpatients at a TB specialist hospital in KwaZulu-Natal Province, an area considered the epicenter for MDR-TB coinfection in South Africa. Four aspects of stigma and their association with major depression were assessed through individual interviews: 1) community and 2) patient perspectives toward TB, and 3) community and 4) patient perspectives toward HIV. A major depressive episode (MDE), HIV coinfection, and low income were significantly associated with greater stigma subscales. Based on an adjusted regression model, the MDE was the only factor independently associated with (all aspects of) stigma. These results indicate the potential utility of addressing stigma associated with the MDE as an important step in improving health-seeking behavior to promote adherence and retention in care.

Exposure to waste sites and their impact on health: a panel and geospatial analysis of nationally representative data from South Africa, 2008-2015.

BACKGROUND: Rapid population growth, urbanisation, and economic development have led to an unprecedented number of waste sites in developing countries. This challenge has become a contentious international relations issue, with an unsustainable amount of waste and its health consequences often being borne by developing countries. However, little national-level evidence is available in sub-Saharan Africa to quantify the association between exposure to waste sites and health. METHODS: We used panel data from the South African National Income Dynamics Study (SA-NIDS) to investigate the association between exposure to waste sites and asthma, tuberculosis, diabetes, and depression. The SA-NIDS is a panel survey of a nationally representative sample in South Africa, which includes data reporting the health status of 32 255 individuals between 2008 and 2015. The study exposure was distance of households, in km, to the nearest waste site, derived from waste site geospatial locations from the South Africa Waste Information System. FINDINGS: We observed a substantial increase in exposure of households to waste sites between 2008 and 2015. The median distance between study households and waste sites decreased from 68·3 km (IQR 31·1-111·7) to 8·5 km (3·0-23·7). Residing within 5 km of a waste site was significantly associated with asthma (adjusted relative risk 1·41; 95% CI 1·20-1·64), tuberculosis (1·18; 1·02-1·36), diabetes (1·25; 1·05-1·49), and depression (1·08; 1·03-1·14). The association persisted even after controlling for multiple socioeconomic factors. INTERPRETATION: We identified multiple adverse health outcomes in individuals living close to waste sites at a national level in South Africa, suggesting the need to reduce the number and size of waste sites to diminish harmful effects on health and wellbeing for communities living in close proximity to such sites.

Neurocognitive functioning in MDR-TB patients with and without HIV in KwaZulu-Natal, South Africa.

OBJECTIVES: Optimising medication adherence is one of the essential factors in reversing the tide of a TB-HIV syndemic in sub-Saharan Africa, especially South Africa. Impairment in key neurocognitive domains may impair patients' ability to maintain adherence to treatment, but the level of cognition and its relationship to HIV status has not been examined in individuals with drug-resistant TB. We therefore investigated performance on several key neurocognitive domains in relationship to HIV status in a multidrug-resistant tuberculosis patients (MDR-TB) sample. METHODS: We enrolled microbiologically confirmed MDR-TB inpatients at a TB-specialist referral hospital in KwaZulu-Natal province, South Africa. We collected cross-sectional data on sociodemographic, clinical and neurocognitive function (e.g. attention, memory, executive functioning, language fluency, visual-spatial, eye-hand coordination). For the primary analysis, we excluded participants with major depressive episode/substance use disorder (MDE/SUD). We fitted adjusted Poisson regression models to explore the association between HIV and neurocognitive function. RESULTS: We enrolled 200 people with MDR-TB; 33 had MDE/SUD, and data of 167 were analysed (151 HIV+, 16 HIV-). The mean age of participants was 34.2 years; the majority were female (83%), and 53% had not completed secondary school. There was evidence of impaired neurocognitive functioning across all domains in both HIV+/- study participants. Based on the regression analyses, individuals with co-infection (MDR-TB/HIV+), as well as those who had longer duration of hospital stays experienced significantly lower cognitive performance in several domains. Poor cognitive performance was significantly related to older age and lower educational attainment. The presence of major depression or substance use disorders did not influence the significance of the findings. CONCLUSIONS: Adults with MDR-TB have significant neurocognitive impairment, especially if HIV positive. An integrated approach is necessary in the management of MDR-TB as cognitive health influences the ability to adhere to chronic treatment, clinical outcomes and functionality.

OBJECTIFS: L'optimisation de l'adhésion au traitement est l'un des facteurs essentiels pour inverser la tendance d'un syndrome TB-VIH en Afrique subsaharienne, en particulier en Afrique du Sud. Des déficiences dans des domaines neurocognitifs clés peuvent entraver la capacité des patients à maintenir l'adhésion au traitement, mais le niveau de cognition et sa relation avec le statut VIH n'ont pas été examinés chez les personnes atteintes de TB résistante aux médicaments. Nous avons donc étudié les performances de plusieurs domaines neurocognitifs clés en relation avec le statut VIH dans un échantillon de tuberculose multirésistante (TB-MDR). MÉTHODES: Nous avons recruté des patients hospitalisés pour une TB-MDR confirmée microbiologiquement dans un hôpital de référence spécialisé dans la TB dans la province du KwaZulu-Natal, en Afrique du Sud. Nous avons recueilli des données transversales sur les fonctions sociodémographiques, cliniques et neurocognitives (par exemple l'attention, la mémoire, le fonctionnement exécutif, la maîtrise du langage, la coordination visuelle-spatiale et œil-main). Pour l'analyse primaire, nous avons exclu les participants souffrant d'un épisode dépressif majeur ou d'un trouble lié à la consommation de substances (EDM/TCS). Nous avons appliqué des modèles de régression de Poisson ajustés pour explorer l'association entre le VIH et la fonction neurocognitive. RÉSULTATS: Nous avons recruté 200 personnes atteintes de TB-MDR, 33 d'entre elles étaient atteintes de EDM/TCS, les données des 167 autres ont été analysées (151 VIH-positives, 16 VIH-négatives). L'âge moyen des participants était de 34,2 ans; la majorité étaient des femmes (83%) et 53% n'avaient pas terminé leurs études secondaires. Les participants à l'étude VIH+ et VIH- présentaient des signes de dysfonctionnement neurocognitif dans tous les domaines. D'après les analyses de régression, les personnes coinfectées (TB-MDR/VIH), ainsi que celles qui ont été hospitalisées pendant une longue période, présentent des performances cognitives nettement inférieures dans plusieurs domaines. Les mauvaises performances cognitives étaient significativement liées à l'âge plus élevé et à un niveau d'éducation plus faible. La présence d'une dépression majeure ou de troubles liés à la consommation de substances n'a pas influencé la signification des résultats. CONCLUSIONS: Les adultes atteints de TB-MDR présentent une importante déficience neurocognitive, surtout s'ils sont VIH-positifs. Une approche intégrée est nécessaire dans la prise en charge de la TB-MDR car la santé cognitive influence la capacité d'adhésion à un traitement chronique, les résultats cliniques et la fonctionnalité.

Predictors of quality of life among community psychiatric patients in a peri-urban district of Gauteng Province, South Africa.

BACKGROUND: Few studies on quality of life (QoL) among people with mental illness have been conducted in South Africa, and none in community dwelling individuals. However, a greater understanding of subjective QoL may inform community-based medical, psychotherapeutic, or social interventions. This study examined the QoL, clinical and sociodemographic characteristics of psychiatric patients attending community mental health clinics in the Gauteng Province of South Africa. METHODS: A cross sectional interview-based study was conducted with 121 adult patients attending community psychiatric clinics. To reduce the impact of acute psychiatric symptoms on subjective QoL, only clinically stable patients were included. Sociodemographic details and clinical characteristics were recorded. Subjective QoL was assessed using the World Health Organization QOL-Bref scale (WHOQOL-Bref), and severity of psychiatric illness measured with the Brief Psychiatric Rating Scale, expanded version 4.0 (BPRS-E). RESULTS: Just over half of the sample rated their overall QoL as good or very good. Residual psychiatric symptomatology was the strongest predictor of a poor QoL in all four domains of the WHOQOL-Bref. The most severe BPRS scores were for the symptoms of depression, anxiety and somatic concern. Perceived social support significantly predicted a better QoL in the psychological, social relationships and environmental domains. CONCLUSION: This study highlights the negative impact of residual psychiatric symptoms on subjective QoL and the importance of social support in enhancing QoL.

Neurocognitive Impairment Risk Among Individuals With Multiple Drug-Resistant Tuberculosis and Human Immunodeficiency Virus Coinfection: Implications for Systematic Linkage to and Retention of Care in Tuberculosis/Human Immunodeficiency Virus Treatment.

Although neurocognitive impairment (NCI) is a well-recognized challenge in human immunodeficiency virus (HIV), there is little evidence regarding it among individuals with multiple drug-resistant tuberculosis (MDR-TB) within HIV endemic sub-Saharan Africa. The extent of NCI risk, particularly HIV-associated neurocognitive disorders (HAND) risk, was investigated in 200 microbiologically confirmed inpatients with MDR-TB at a TB-specialist hospital in KwaZulu-Natal Province, South Africa. Within this population, the prevalence of HIV coinfection, major depressive episode, and substance use disorder was 89.50%, 10.50%, and 7.00%, respectively. After excluding individuals with major depressive episode/substance use disorder and monoinfection (i.e., MDR-TB without HIV), the prevalence of HAND risk was 43.5%. Older and low-income individuals had significantly greater odds of HAND risk, whereas those with family members/relatives who work(ed) in the health services had lower odds. The role of timely linkage to and retention of care in TB/HIV treatment to offset cognitive decline in MDR-TB/HIV coinfected individuals needs to be investigated further.

Major depression and household food insecurity among individuals with multidrug-resistant tuberculosis (MDR-TB) in South Africa.

PURPOSE: Household food insecurity in South Africa is a pervasive public health challenge. Although its link to chronic health conditions is well established, its relationship to mental illness, particularly major depression, is not well-understood. Despite KwaZulu-Natal Province being the epicenter of the drug-resistant tuberculosis (MDR-TB) epidemic, and having the largest share of poverty in South Africa, this relationship remains unexamined. This study investigated the association between major depressive episode (MDE) and household food insecurity among individuals with MDR-TB. METHODS: We enrolled and interviewed 141 newly admitted microbiologically confirmed MDR-TB inpatients at a specialized TB hospital in KwaZulu-Natal Province, South Africa. Logistic regression models were fitted to assess the relationship between MDE and household food insecurity, while accounting for socio-demographic status (e.g., age, gender, education, marital status, social grant status, income, and preference for living in one's community). RESULTS: The prevalence of MDE and household food insecurity was 11.35% and 21.01%, respectively. MDE was significantly associated with household food insecurity (aOR 4.63, 95% CI 1.17-18.38). Individuals who are female (aOR 6.29, 95% CI 1.13-35.03), young (aOR 8.86, 95% CI 1.69-46.34), have low educational attainment (aOR 6.19, 95% CI 1.70-22.59) and receive social grants (aOR 7.60, 95% CI 2.36-24.48) were most at risk of household food insecurity. CONCLUSIONS: MDE in individuals with MDR-TB was significantly associated with household food insecurity, independent of socio-economic status. Although MDR-TB is not exclusively a disease of the poor, individuals from socio-economically disadvantaged backgrounds (e.g., female, young adults, low education, and social grant recipients) were more likely to experience household food insecurity. Our study underscores the need to address the co-occurring cycles of food insecurity and untreated MDE in South Africa.

Spatial structure of depression in South Africa: A longitudinal panel survey of a nationally representative sample of households.

Wider recognition of the mental health burden of disease has increased its importance as a global public health concern. However, the spatial heterogeneity of mental disorders at large geographical scales is still not well understood. Herein, we investigate the spatial distribution of incident depression in South Africa. We assess depressive symptomatology from a large longitudinal panel survey of a nationally representative sample of households, the South African National Income Dynamics Study. We identified spatial clusters of incident depression using spatial scan statistical analysis. Logistic regression was fitted to establish the relationship between clustering of depression and socio-economic, behavioral and disease risk factors, such as tuberculosis. There was substantial geographical clustering of depression in South Africa, with the excessive numbers of new cases concentrated in the eastern part of the country. These clusters overlapped with those of self-reported tuberculosis in the same region, as well as with poorer, less educated people living in traditional rural communities. Herein, we demonstrate, for the first time, spatial structuring of depression at a national scale, with clear geographical 'hotspots' of concentration of individuals reporting new depressive symptoms. Such geographical clustering could reflect differences in exposure to various risk factors, including socio-economic and epidemiological factors, driving or reinforcing the spatial structure of depression. Identification of the geographical location of clusters of depression should inform policy decisions.

Psychosocial and behavioural interventions towards HIV risk reduction for serodiscordant couples in Africa: A systematic review.

BACKGROUND: Sexual transmission of HIV frequently occurs in the context of a primary relationship between two partners; however, HIV prevention interventions generally focus on individuals at risk, rather than specifying couples as a unit of change and analysis, neglecting the crucial role that partners may play in sexual behaviour. This article reviews published scientific literature addressing couple-oriented HIV counselling and testing and other behavioural interventions using an online search for peer-reviewed papers. METHODS: A systematic review was conducted to evaluate what has been published on psychosocial interventions in HIV serodiscordant couples in Africa. Electronic databases were searched from January 1990 to December 2015. Quality assessment of included studies was conducted using the Systematic Appraisal of Quality in Observational Research tool. RESULTS: The electronic database searches initially retrieved 493 records; after cross-referencing, removing duplicates and applying strict inclusion and exclusion criteria, only eight papers were included in this review. All the studies under review showed that couples-focused counselling and educational programmes were associated with positive outcomes including reduced HIV transmission, reduced unprotected sex, increased rates of status disclosure and high levels of treatment adherence. CONCLUSIONS: The literature on interventions for HIV serodiscordant couples is sparse. However, most interventions indicate that couples-focused interventions are effective in HIV risk reduction. In spite of the limited available data and repeated recommendations by different health authorities, couple-centred approaches to HIV prevention have not been implemented on a large scale.

Sexual trauma and post-traumatic stress among African female refugees and migrants in South Africa.

BACKGROUND: While there is considerable research in developed countries on the nature and extent of post-traumatic stress among refugees and migrants, few report on female Africans migrating within Africa. AIM: The aim of this study was to investigate the association between exposure to traumatic life events and post-traumatic stress disorder risk in refugees and migrants in Durban, South Africa, with specific focus on sexual trauma events among women. METHODS: Interviews were conducted on 157 consenting non-South African adults using a sociodemographic questionnaire, Life Events Checklist (documenting traumatic events experienced) and the Harvard Trauma Questionnaire (measuring post-traumatic symptomatology). Associations between total number of traumatic events and post-traumatic stress were explored using adjusted regression models. RESULTS: The results of one model indicated that greater numbers of traumatic life events experienced by women were associated with raised odds of post-traumatic stress disorder risk (ß = 1.48; p < 0.001). Another model indicated that exposure to sexual trauma events were associated with greater odds of post-traumatic stress disorder risk (ß = 4.09; p = 0.02). CONCLUSION: Our findings highlight the critical importance of mental health service for females with history of sexual traumatic events for this vulnerable population.

Income inequality and depression: a systematic review and meta-analysis of the association and a scoping review of mechanisms.

Most countries have witnessed a dramatic increase of income inequality in the past three decades. This paper addresses the question of whether income inequality is associated with the population prevalence of depression and, if so, the potential mechanisms and pathways which may explain this association. Our systematic review included 26 studies, mostly from high-income countries. Nearly two-thirds of all studies and five out of six longitudinal studies reported a statistically significant positive relationship between income inequality and risk of depression; only one study reported a statistically significant negative relationship. Twelve studies were included in a meta-analysis with dichotomized inequality groupings. The pooled risk ratio was 1.19 (95% CI: 1.07-1.31), demonstrating greater risk of depression in populations with higher income inequality relative to populations with lower inequality. Multiple studies reported subgroup effects, including greater impacts of income inequality among women and low-income populations. We propose an ecological framework, with mechanisms operating at the national level (the neo-material hypothesis), neighbourhood level (the social capital and the social comparison hypotheses) and individual level (psychological stress and social defeat hypotheses) to explain this association. We conclude that policy makers should actively promote actions to reduce income inequality, such as progressive taxation policies and a basic universal income. Mental health professionals should champion such policies, as well as promote the delivery of interventions which target the pathways and proximal determinants, such as building life skills in adolescents and provision of psychological therapies and packages of care with demonstrated effectiveness for settings of poverty and high income inequality.

A comparative study of socio-demographic and substance use correlates in early-onset psychosis.

BACKGROUND: Comorbid substance use, particularly cannabis among adolescents with mental illness, is a major public health concern in developing countries with limited mental health resources. Better understanding of the association between cannabis use and other polysubstance use and early mental illness will provide for more targeted early interventions. AIM: This aim of this study was to examine the socio-demographic profile and cannabis use characteristics among adolescents with first-episode early-onset psychosis (EOP) and compare with age-matched and gender-matched adolescents with first-episode non-psychotic mental illness (controls). METHOD: Forty-five adolescents with first-episode EOP and 45 controls were assessed using a clinical interview, Positive and Negative Syndrome Scale and World Health Organization Alcohol, Smoking and Substance Involvement Screening test (ASSIST) for substance-related problems. RESULTS: There were significant socio-demographic differences among the adolescents with EOP (73% Black, 64% from low family income, 44% from rural areas) compared with controls (24% Black, 53% from low family income, 2% from rural areas). Although there was no difference in lifetime cannabis use, EOP adolescents differed in motivation for cannabis use, had increased current cannabis use (38%, P = 0.01) and more frequent use (52%, P = 0.04) compared with controls (16% current and 18% frequent use). EOP adolescents reported more hazardous use with higher ASSIST mean cannabis-specific involvement scores (EOP 10,2; controls 2,3; P = 0.004). CONCLUSION: The differences in socio-demographic variables may reflect the marked disparity in access to mental health care for rural Black youth. Psychotic youth may be more vulnerable to comorbid cannabis-related problems than other mentally ill adolescents. The study highlights the need for early introduction of substance use interventions among adolescents with mental illness.

Epidemiological patterns of mental disorders and stigma in a community household survey in urban slum and rural settings in Kenya.

PURPOSE: This study investigated the epidemiological patterns of mental illness and stigma in community households in Kenya using a cross-sectional community household survey among 846 participants. METHODS: A cross-sectional community household survey was conducted around urban slum (Kangemi) and rural (Kibwezi) selected health facilities in Kenya. All households within the two sites served by the selected health facilities were included in the study. To select the main respondent in the household, the oldest adult who could speak English, Kiswahili or both (the official languages in Kenya) was selected to participate in the interview. The Opinion about Mental Illness in Chinese Community (OMICC) questionnaire and the MINI-International Neuropsychiatric Interview-Plus Version 5 (MINI) tools were administered to the participants. Pearson's chi-square test was used to compare prevalence according to gender, while adjusted regression models examined the association between mental illness and views about mental illness, stratified by gender. RESULTS: The overall prevalence of mental illness was 45%, showing gender differences regarding common types of illness. The opinions about mental illness were similar for men and women, while rural respondents were more positively opinionated than urban participants. Overall, suffering from mental illness was associated with more positive opinions among women and more negative opinions among men. CONCLUSION: More research is needed into the factors explaining the observed differences in opinion about mental illness between the subgroups, and the impact of mental illness on stigma in Kenya in order to create an evidence-based approach against stigma.
