Psychometric evaluation of the Kessler 10 measure of psychosocial distress using the 2022 South African population-based household survey
The Kessler Psychological Distress Scale (K10) is widely used in epidemiological research but requires validation within South Africa’s multilingual setting. This study evaluated the psychometric properties of the K10 using national population-based survey data and Item Response Theory (IRT). Graded Response Models (GRM) were used to assess factor loadings, item discrimination, and difficulty parameters, while Test Information Curves evaluated me…
Piloting the feasibility of a population-based joint TB-HIV survey in KwaZulu-Natal Province, South Africa, 2019
South Africa bears a high burden of infectious diseases, including intersecting epidemics of human immunodeficiency virus (HIV) and tuberculosis (TB). Among people living with HIV, TB is the predominant cause of death. Since 2002, South Africa has conducted six national population-based HIV surveys, and its first national TB prevalence survey between 2017 and 2019. Given the epidemiologic overlap of these conditions and dwindling resources, a joi…
Prevalence, associated factors and geospatial patterns of HIV drug resistance in South Africa among the virally unsuppressed adults
South Africa bears the highest HIV burden globally, with substantial antiretroviral therapy (ART) scale-up. HIV drug resistance (HIVDR) threatens progress toward UNAIDS 95–95-95 targets. We assessed national HIVDR prevalence and associated factors among virally unsuppressed adults in 2017, before dolutegravir (DTG)-rollout. Secondary analysis of the 2017 national HIV household survey, included 1 253 virally unsuppressed (defined as ≥ 1 000 copies…
Heterogeneity in Covid-19 infection among older persons in South Africa
Background: The 2021 World Health Organization study on the impact of COVID-19 on older people (≥60 years) in the African region highlighted the difficulties they faced as the virus spread across borders and dominated the way of life. These difficulties included disruptions to both essential health care services and social support, as well as disconnections from family and friends. Among those who contracted COVID-19, the risks of severe illness,…
Seroprevalence survey of anti-Sars-CoV-2 antibody and associated factors in South Africa

This study reports findings of a national household population SARS-CoV-2 serosurvey in people 12 years and older in South Africa. This cross-sectional multi-stage random stratified cluster survey undertaken from November 2…

This paper presents key findings from the fifth HIV prevalence, incidence, and behaviour survey conducted in 2017 following policy, programme, and epidemic change since the prior survey was conducted in 2012. A cross-section…

In this paper, risk compensation among individuals on antiretroviral therapy (ART), using the 2017 South African national survey on HIV, is explored. A multi-stage stratified cluster random sampling approach was used to realize 11,130 participants 15 years and older. Logistic regression analysis assessed the association between multiple sexual partners, condom use at last sexual encounter, consistency of condom usage and potential explanatory var…

Determinants of Confidence in Overall Knowledge About Covid-19 Among Healthcare Workers in South Africa
Background: Adequate information and knowledge about COVID-19 has been shown to induce the confidence and positive performance among healthcare workers (HCWs). Therefore, assessing the relationship between confidence in knowledge and associated factors among HCWs is vital in the fight against COVID-19. This paper investigates factors associated with HCWs' confidence in their overall knowledge about COVID-19 in South Africa in the early stages of …
Preparedness for self-isolation or quarantine and lockdown in South Africa
The findings highlight the challenge of implementing self-isolation or quarantine in a country with different and unique social contexts. There is a need for public awareness regarding the importance of self-isolation or quarantine as well as counter measures against contextual factors inhibiting this intervention, especially in impoverished communities
Prevalence and factors associated with intimate partner violence among the adolescent girls and young women in South Africa

Knowledge, attitudes and prevention practices regarding HIV/Aids among barbers in Ho municipality, Ghana
The barbing industry poses particular public health risks if it is not conducted in a safe and hygienic manner. These risks can lead to the transmission of infectious diseases like the Human Immunodeficiency Virus (HIV) to the barbers or their clients. This study investigated the knowledge, attitudes and prevention practices regarding HIV transmission among barbers in the Ho Municipality. A descriptive cross-sectional design was employed. A prete…
Towards achieving the 90–90–90 HIV targets
South Africa appears to be on track to achieve the first 90 indicator by 2020. However, it is behind on the second 90 indicator with ART coverage that was ~ 20-percentage points below the target among people who knew their HIV status, this indicates deficiencies around linkage to and retention on ART. Overall viral suppression among those on ART is approaching the target at 87.4%, but this must be interpreted in the context of low reported ART co…
Determinants of excellent/good self-rated health among HIV positive individuals in South Africa
To have positive health effects and improve the perceived health status for PLWH social interventions should seek to enhance to support for the elderly HIV-positive individuals, and address the challenge of socio-economic inequalities and underlying comorbid conditions resulting in hospitalization
Determinants of HIV infection among adolescent girls and young women aged 15–24 years in South Africa
These findings support the need to design combination prevention interventions which simultaneously address socio-economic drivers of the HIV epidemic, promote education, equity and access to schooling, and target age-disparate partnerships, inconsistent condom use and risky alcohol consumption
New insights into HIV epidemic in South Africa
This article presents key findings from the 2012 HIV prevalence, incidence and behaviour survey conducted in South Africa and explores trends in the HIV epidemic. A representative household based survey collected behavioural and biomedical data among people of all ages. Chi-squared test for association and formal trend tests (2002, 2005, 2008 and 2012) were used to test for associations and trends in the HIV epidemic across the four surveys. In 2…
HIV risk perception and behavior among medically and traditionally circumcised males in South Africa
There is a need to strengthen and improve the quality of the counselling component of VMMC with the focus on education about the real and present risk for HIV infection associated with multiple sexual partners and alcohol abuse following circumcision
HIV Serostatus Disclosure to Sexual Partners Among Sexually Active People Living with HIV in South Africa
HIV Status and Labor Market Participation in South Africa
We use econometric methods based on the propensity score to estimate the causal effect of HIV status on employment outcomes in South Africa. Relying on rich data from a national survey, which included HIV testing, we control for systematic differences between HIV-positive and HIV-negative individuals. We provide the first nationally representative estimates of the impact of HIV status on employment outcomes for southern Africa. Being HIV positive…

Epidemiology of health and vulnerability among children orphaned and made vulnerable by HIV/Aids in sub-Saharan Africa
The HIV/AIDS epidemic in sub-Saharan Africa has already orphaned a generation of children, and it is projected that by 2010, 18 million African children under the age of 18 are likely to be orphans from this single cause (UNICEF, 2005, The state of the Worlds Children: Childhood under threat. New York: UNICEF). Results from a Kellogg funded OVC project (Skinner et al., 2004, Definition of orphaned and vulnerable children. Cape Town: HSRC) support…
