Exploring HIV status as a mediator in the relationship of psychological distress with socio-demographic and health related factors in South Africa: findings from the 2012 nationally representative population-based household survey.

BACKGROUND: Psychological distress as measured by mental disorders like depression and anxiety is more prevalent in people living with HIV (PLHIV) than in the general population. However, the relationship between mental disorders and HIV is complex and bidirectional. Improved understanding of the relationship between mental disorders and HIV is important for designing interventions for this group. This paper explores the interrelationships of psychological distress with HIV and associated socio-demographic and health-related factors. METHODS: This secondary data analysis used the 2012 South African population-based household survey on HIV collected using a cross-sectional multi-stage stratified cluster sampling design. Generalized structural equation modelling (G-SEM) path analysis was used to explore the direct and indirect relationships of socio-demographic, health and HIV-related factors with psychological distress as measured by Kessler 10 scale using HIV status as a moderator variable. RESULTS: A total of 20,083 participants were included in the study, 21.7% reported psychological distress, of whom (32.6%) were HIV positive. In the final path model with HIV status as a moderator, psychological distress was significantly more likely among age group 25-49 years (AOR: 1.4 [95% CI 1.3-1.6]), age 50 years and older, (AOR: 1.4 [95% CI 1.2-1.6]), females (AOR: 1.6 [95% CI 1.4-1.8]), high risk drinkers (AOR: 1.9 [1.6-2.2]) hazardous drinkers (AOR: 4.4 [95% CI 3.1-6.3]), ever tested for HIV (AOR: 1.2 [95% CI 1.1-1.3]). Psychological distress was significantly less likely among the married [AOR: 0.8 (0.7-0.9)], other race groups [AOR: 0.5 (0.5-0.6)], those with secondary level education (AOR: 0.9 [95% CI 0.8-0.9]), and tertiary level education (AOR: 0.7 [95% CI 0.6-0.9]), those from rural informal [AOR: 0.8 (0.7-0.9)], and rural formal [AOR: 0.8 (0.7-0.9)] areas and those who rated their health as excellent/good [AOR: 0.4 (0.4-0.5)]. CONCLUSION: The findings highlight the importance of designing tailored interventions targeted at psychological distress among PLHIV especially the elderly, females, those with no education and / or low education attainment and those residing in informal urban areas.

Social distancing behaviour: avoidance of physical contact and related determinants among South Africans: twelve days into the COVID-19 lockdown.

Social distancing behaviour is a primary preventive measure for reducing COVID-19 transmission. Improved understanding of factors associated with adherence to social distancing is vital for mitigating the impact of COVID-19 in South Africa. The study assessed adherence to social distancing and its associated factors during the state-implemented lockdown in South Africa. Data was analysed from a large-scale public survey conducted in South Africa from 8 to 29 April 2020, which was administered online and telephonically. Invitations to participate were distributed widely on local websites and social media networks, including on a data-free platform. Adherence to social distancing was measured by self-report of having engaged in close physical contact with someone outside the home. Simple and multiple logistic regression models examined the association between social distancing and potential explanatory variables. Of the 17,586 participants, 9.2% came into close physical contact with a person outside their home by hugging, kissing, or shaking hands during the past 7 days. The odds of coming into close physical contact with other people were significantly higher for males, students, and those with incorrect knowledge on physical distancing, angry attitudes about the lockdown, lack of confidence in the government response, high-risk perception, movement out of the local area, travelling to shops using public transport, households with communal water facilities and higher household size. The 25-59-year olds compared to 18-24-year olds, and the White and Indian/Asian compared to the African population groups had significantly lower odds of close physical contact with others outside the home. The study identifies subgroups of individuals for whom public health interventions to improve adherence to social distancing should be prioritised and tailored. Interventions and policies should take cognisance of the social determinants of health as well as culturally accepted greeting practices like hand shaking.

Concurrent allergy and helminthiasis in underprivileged urban South African adults previously residing in rural areas.

This study investigated whether prior exposure to helminths (Ascaris IgE, Ascaris eggs and Trichuris eggs) either in childhood or in adulthood, and residence in rural and resource-limited urban areas influence allergy outcomes (asthma, rhinitis, IgE atopy and food allergy) in a South African population. Participants historical and present allergies data were collected through questionnaires and clinical record files. Coproscopy and immunoassays (ImmunoCAPTM Phadiatop, total IgE and allergen-specific fx3 IgE immunoassays and Ascaris IgE radioallergosorbent [RAST] tests) were used for active helminthiasis and allergy screens respectively. Data were analysed using logistic regression analysis, and models were adjusted for age, gender and locality. High Ascaris IgE was significantly associated with asthma (adjusted odds ratio [aOR] = 2.20, p = .047), IgE atopy (aOR = 18.18, p < .0001) and food allergy (aOR = 14.47, p < .0001). Asthma was significantly less likely among participants with Ascaris eggs (aOR = 0.43, p = .048) and Trichuris eggs (aOR = 0.36, p = .024). The findings of co-occurrent helminthiasis and allergic disorders in a population that has resided both in rural and peri-urban informal settlements both oppose and agree with two main notions of the hygiene hypothesis that (i) individuals residing in rural settings with poor sanitation and geohelminth infection are less prone to allergy, and (ii) helminth infections protect against allergy respectively. Further research is warranted.

HIV Prevalence and Associated Factors Among Men in South Africa 30 Years into the Epidemic: The Fifth Nationwide Cross-Sectional Survey.

We investigated HIV prevalence and associated factors among men ≥ 15 years in South Africa using data from a 2017 nationwide cross-sectional survey. HIV prevalence was 10.5% among 6 646 participants. Prevalence increased from 4.1% in the younger men (15-24 years), 12.5% in young men (25-34 years) to 12.7% in older men (≥ 35 years). Odds of being infected with HIV were lower among younger men who had secondary level education and those who reported poor/fair self-rated health. Young and older men of other race groups had lower odds of HIV infection. Odds of infection were lower among young men who had moderate/high exposure to HIV communication programmes. Men not aware of their HIV status had higher odds of HIV infection, including older men who never married. Improved access to education, behavioral change programmes, and awareness of HIV status are necessary to reduce the risk of HIV infection among Black African men.

Racial disparities in psychological distress in post-apartheid South Africa: results from the SANHANES-1 survey.

PURPOSE: South Africa has long endured a high prevalence of mental disorders at the national level, and its unique social and historical context could be a contributor to an increased risk of mental health problems. Our current understanding is limited regarding the relative importance of various social determinants to mental health challenges in South Africa, and how existing racial inequities may be explained by these determinants. METHODS: This study attempted to elucidate potential social determinants of mental health in South Africa using data from the nationally representative South African National Health and Nutrition Examination Survey (SANHANES-1). The main outcome of interest was psychological distress, measured with the Kessler-10 scale. Hierarchical linear regression models included covariates for demographic and socioeconomic factors, count of traumatic events, and a series of stress-related constructs. Analyses were conducted on two populations: the entire sample (n = 15,981), and the African subpopulation (n = 10,723). RESULTS: Regression models on the entire sample indicated racial disparities in psychological distress, with Africans experiencing higher distress than White and Coloured individuals. Results within the African sub-population indicated geo-spatial disparities, with Africans in formal urban settings experiencing higher psychological distress than those living in formal and informal rural locales. Across both samples, results indicated a cumulative association between count of stressors and traumatic events and distress. CONCLUSION: We found racial disparities across several mental health-related domains. Africans had greater exposure to traumatic events, social stressors, and psychological distress. This research is a necessary foundation for public health interventions and policy change to effectively reduce inequities in psychological distress.

Factors associated with age-disparate sexual partnerships among males and females in South Africa: a multinomial analysis of the 2012 national population-based household survey data.

BACKGROUND: In South Africa, age-disparate to sexual relationships where the age difference between partners is 5 years or greater is an important contributor to the spread of HIV. However, little is known about the predictors of age-disparate sexual relationships. This study investigates factors associated with age-disparate sexual relationships among males and females in South Africa. METHODS: This analysis used the 2012 nationally representative population-based household survey conducted using multi-stage stratified cluster sampling design. Multivariate multinomial stepwise logistic regression models were used to determine factors associated with age-disparate sexual relationships. RESULTS: Of 15,717 participants, who responded to the question on age-disparate sexual relationships, 62% males versus 58.5% females had partners within 5 years older or younger, 34.7% of males versus 2.7% of females had partners at least 5 years younger and 3.3% of males versus 38.8% of females had partners at least 5 years older. Among both males and females predictors of age-disparate sexual relationships were education, employment, socioeconomic status, locality type, age at sexual debut, condom use at last sexual act and HIV status while race was also an additional predictor for among females. Including unprotected sex and risk of HIV infection among adolescent girls and young women with sexual partners 5 years older their age. CONCLUSIONS: This study suggest that there is a need for reprioritizing the combination of behavioural and structural interventions to address risky sexual behaviours, unprotected sex, poverty, limited education and gender inequitable norms related to age-disparate sexual relationships and HIV.

Trends and correlates of HIV prevalence among adolescents in South Africa: evidence from the 2008, 2012 and 2017 South African National HIV Prevalence, Incidence and Behaviour surveys.

BACKGROUND: Adolescents are at increased risk of HIV infection compared to other age groups. There is an urgent need for strategic information that will inform programmes to reduce risk and vulnerability to HIV and reverse the pattern of increasing HIV infection as they transition to adulthood. This paper analysed trends and factors associated with HIV prevalence among adolescents in South Africa using the national HIV population-based household surveys conducted in 2008, 2012 and 2017. METHODS: All three surveys used a multistage cross-sectional design. A trend analysis was conducted to assess the differences in HIV prevalence and covariates overtime using P-trend Chi-squared statistic. Univariate and multivariate logistic regression models were used to determine factors associated with HIV prevalence. RESULTS: Overall there was a significant increase in HIV prevalence among adolescents aged 12-19 years from 3.0% (n = 2892) in 2008 to 3.2% (n = 4829) in 2012 and 4.1% (n = 3937) in 2017 (p = 0.031). The odds of being HIV positive among adolescents aged 12-19 years was significantly higher among females [AOR = 2.24; 95% CI (1.73-2.91); p < 0.001] than males, those residing in KwaZulu-Natal province [AOR = 2.01; 95% CI (1.-3.99); p = 0.027] than Northern Cape, and those who did not attend an educational institution and were unemployed [AOR = 2.66; 95% CI (1.91-3.67); p < 0.001] compared to those attending an educational institution. The odds were significantly lower among Whites [AOR = 0.29; 95% CI (0.09-0.93); p = 0.037], Coloureds [AOR = 0.21; 95% CI (0.11-0.37); p ≤ 0.001] and Indian/Asian [AOR = 0.08; 95% CI (0.02-0.34); p = 0.001] population groups than Black Africans. CONCLUSION: The observed increasing trend and gender disparities in HIV prevalence suggests an urgent need for age appropriate and gender specific HIV interventions tailored and targeted at identified drivers of HIV infection among adolescents.

Trends, prevalence and factors associated with hypertension and diabetes among South African adults living with HIV, 2005-2017.

BACKGROUND: Many people are now living longer with HIV due to access to antiretroviral treatment. In turn, there has been an increase in the burden of hypertension and diabetes. The paucity of data on the burden of hypertension and diabetes in adults living with HIV in South Africa is a public health concern. The paper aimed to describe the prevalence and factors associated with hypertension and diabetes among adults living with HIV (ALHIV). METHODS: This was a secondary data analysis of the population based on the South African National HIV Prevalence, Incidence, Behaviour and Communication surveys for 2005, 2008 and 2017. Descriptive statistics were used to summarise the characteristics of the study sample. Bivariate and multivariate logistic regression analyses were used to determine factors associated with hypertension and diabetes. RESULTS: The total study population of ALHIV aged 25 years and older was 978, 1023 and 2483 for 2005, 2008 and 2017. The prevalence of hypertension showed an increasing trend at 11.8% in 2005, 9.5% in 2008 and 14.3% in 2017. The prevalence of diabetes was 3.3% in 2005, 2.8% in 2008 and 3.2% in 2017. Increased odds of hypertension among adults living with HIV were consistently associated with being female and the age group 45 years older across all the survey years, including pensioners and the sick, living in urban areas, high risk of hazardous alcohol consumption, diabetes and heart disease. Increased odds of diabetes were consistently associated with hypertension across all the survey years, including age group 45 years and older, and poor health. While having a secondary level of education and above was protective against diabetes. CONCLUSION: The study showed that the prevalence of hypertension is high and has increased over time among adults living with HIV while the prevalence of diabetes has remained constant. Findings identified factors consistently associated with the prevalence of both diseases overtime, including contemporary risk factors that should be targeted in the integrated management of chronic disease and HIV care model.

Prevalence and factors associated with intimate partner violence among the adolescent girls and young women in South Africa: findings the 2017 population based cross-sectional survey.

BACKGROUND: Evidence indicate that intimate partner violence (IPV) is disturbingly high among South African adolescent girls and young women (AGYW). Understanding prevalence and risk factors for IPV among these emerging adults is critical for developing appropriate interventions to prevent adverse health outcomes later in life. This study investigates the prevalence and factors associated with lifetime physical IPV experience among AGYW, aged 15-24 years, using the South African national HIV prevalence, incidence, behaviour and communication survey conducted in 2017. METHODS: The data used in this secondary analysis was obtained from a cross-sectional, population-based household survey data, conducted using a multi-stage stratified random cluster sampling approach. Multivariate stepwise backward logistic regression modelling was used to determine factors associated with IPV. RESULTS: Of 716 AGYW that responded to the two commonly answered questions on IPV, 13.1% (95% CI: 9.6-17.6) indicated that they experienced IPV. The odds of reporting experiences of IPV were significantly lower among AGYW residing in high SES households [AOR = 0.09 (95% CI: 0.02-0.47), p = 0.004] than low SES households, and those residing in rural informal/tribal areas [AOR = 0.01 (95% CI: 0.00-0.22), p = 0.004] than urban areas. AGYW experiencing IPV had higher odds of reporting psychological distress compared to their counterparts [AOR = 4.37 (95% CI, 0.97-19.72), p = 0.054]. CONCLUSION: The findings highlight the need for targeted structural and psychosocial interventions in low SES households and especially in urban areas.

Socio-economic differences in the uptake of HIV testing and associated factors in South Africa.

BACKGROUND: Improved understanding of barriers to HIV testing is important for reaching the first of the UNAIDS 90-90-90 targets, which states that 90% of HIV positive individuals ought to know their HIV status. This study examined socio-economic status (SES) differences in HIV testing uptake and associated factors among youth and adults 15 years and older in South Africa. METHODS: This study used data from a national cross-sectional, population-based household survey conducted in 2017 using a multi-stage sampling design. A composite SES score was created using multiple correspondence analyses of household assets; households were classified into wealth quintiles and dichotomised into low SES/poorest (lowest 3 quintiles) and high SES/less-poor (highest 2 quintiles). Bivariate and multivariate logistic regression models were used to examine factors associated with the uptake of HIV testing in low and high SES households. RESULTS: HIV testing uptake was 73.8 and 76.7% among low and high SES households, respectively, both of which were below the first 90 targets. Among both low and high SES households, increased HIV testing uptake was significantly associated with females than males. The decreased likelihood was significantly associated with residing in rural formal areas than urban areas, those with no education or low levels of educational attainment and alcohol drinkers among low SES households. Whites and Indians/Asians had a decreased likelihood than Black Africans in high SES households. CONCLUSIONS: HIV testing interventions should target males, residents in rural formal areas, those with no or low education and those that consume alcohol in low SES households, including Whites and Indians/Asians from high SES households in order to bridge socio-economic disparities in the uptake of HIV testing. This should entail expanding HIV testing beyond traditional centres for voluntary counselling and testing through outreach efforts, including mobile testing and home-based testing.

Preparedness for self-isolation or quarantine and lockdown in South Africa: results from a rapid online survey.

BACKGROUND: The World Health Organization (WHO) declared the COVID-19 pandemic a public health emergency of international concern. South Africa, like many other countries, initiated a multifaceted national response to the pandemic. Self-isolation and quarantine are essential components of the public health response in the country. This paper examined perceptions and preparedness for self-isolation or quarantine during the initial phase of the pandemic in South Africa. METHODS: The analysis used data obtained from an online quantitative survey conducted in all nine provinces using a data-free platform. Descriptive statistics and multivariable logistic regression models were used to analyse the data. RESULTS: Of 55,823 respondents, 40.1% reported that they may end up in self-isolation or quarantine, 32.6% did not think that they would and 27.4% were unsure. Preparedness for self-isolation or quarantine was 59.0% for self, 53.8% for child and 59.9% for elderly. The odds of perceived possibility for self-isolation or quarantine were significantly higher among Coloureds, Whites, and Indians/Asians than Black Africans, and among those with moderate or high self-perceived risk of contracting COVID-19 than those with low risk perception. The odds were significantly lower among older age groups than those aged 18-29 years, and those unemployed than fully employed. The odds of preparedness for self-isolation or quarantine were significantly less likely among females than males. Preparedness for self, child and elderly isolation or quarantine was significantly more likely among other population groups than Black Africans and among older age groups than those aged 18-29 years. Preparedness for self, child and elderly isolation or quarantine was significantly less likely among those self-employed than fully employed and those residing in informal dwellings than formal dwellings. In addition, preparedness for self-isolation or quarantine was significantly less likely among those with moderate and high self-perceived risk of contracting COVID-19 than low risk perception. CONCLUSION: 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.

Narratives of young black men on barriers to health care and poor health care seeking behaviours at a university setting: a qualitative study.

BACKGROUND: Institutions of higher learning provide education, training, independence and life-long skills for young people. However, for students to achieve their optimal growth and intellectual development they need to be healthy psychologically, mentally and physically. This can be achieved through the development of effective health programs for all university students. This qualitative study was designed to explore Black male students' perspectives and experiences regarding the utilization of on-campus health services at the University of KwaZulu-Natal. METHODS: The study population was selected using purposive sampling. Data were collected using four focus group discussions (FGDs) with 36 participants and three key informant interviews. Thematic analysis was conducted to identify the key patterns and themes that emerged from the data. RESULTS: Emerging themes included poor knowledge and awareness, negative perceptions and attitudes, fear and lack of privacy, and negative experiences leading to poor access and utilization of campus health services. The findings suggested a need for more advocacy and awareness campaigns especially among first year students, campaigns for normalization of sexual health, addressing HIV stigma and discrimination, providing youth friendly services to improve students' use of sexual health services, and ultimately, their overall health and well-being. CONCLUSIONS: The findings give valuable insights from male students on the barriers and potential solutions to campus health services and highlight where improvements can be directed to increase access and use of health services by the study population.

Establishing a community advisory group (CAG) for partnership defined quality (PDQ) towards improving primary health care in a peri-urban setting in KwaZulu-Natal, South Africa.

BACKGROUND: Community advisory groups (CAGs) have been shown to be catalysts who bridge the gap between communities and primary health care facilities by sustaining good working relationships through community engagement to improve the quality of the health care services. This study aimed to explore the establishment, operation, and accomplishments of a CAG towards building a strong partnership between the health facilities and local communities in support of the Partner Defined Quality (PDQ) process, to improve the delivery of quality maternal and neonatal care in a peri-urban setting in the province of KwaZulu-Natal, South Africa. METHODS: The study used a qualitative exploratory research design. Recruitment followed a purposive sampling approach. The study targeted leadership representatives from the community, potential beneficiaries, and health care providers in the selected catchment areas. Participants were identified during community mobilization events that took place during the preparatory stage to ensure key stakeholder support. A participatory research approach was used to discuss membership, composition, the selection criteria, including formulation, and agreement on terms of reference of the CAG membership, roles and responsibilities. A rapid assessment method was used for data collection and analysis of establishment of the CAG, its activities and accomplishments. RESULTS: The community nominated 24 CAG members during the consultative meetings and the organogram provides clear terms of reference, roles and responsibilities. Immediately after inception, the CAG used four indicators (weaknesses, threats and risks, strengths, and opportunities) to review the community and primary health care challenges that affect their communities. These CAG activities were linked with the phases of the PDQ process. The CAG committed itself going forward to continue to create an enabling environment for all stakeholders working to improve the well-being of the community, especially the PDQ teams working on improving the care of pregnant mothers and their babies pre- and post-delivery. CONCLUSION: This work shows that developing community relationships and infrastructure are critical initial stages before embarking on PDQ planning and implementation. Empowerment, local ownership, funding, technical resources and ongoing support are critical elements for sustainability of CAG activities.

Intersectionality of cultural norms and sexual behaviours: a qualitative study of young Black male students at a university in KwaZulu-Natal, South Africa.

BACKGROUND: Sexual risk behaviours that occur among young men are based on dominant notions and practices that prevail in cultural contexts. As such, understanding the intersection of cultural norms and sexual risk behaviours among young men is very important. METHODS: The study used a qualitative design and conducted four focus group discussions with 36 male students who were purposively selected from different levels of study at the University of KwaZulu-Natal. Data were analysed through line-by-line coding, and grouped into emerging themes and sub-themes facilitated by the use of Atlas.ti. RESULT: The findings emphasize that socialisation agents such as the family, peers and community play an important role in prescribing acceptable and unacceptable sexual behaviour of young men. Some of the young men seemed to adhere to prescribed gender norms of what it means to be a man while some rejected them for alternative versions of being a man. In the context of the university environment, these findings reveal that male students cannot make informed decisions regarding condom use when they are intoxicated, and thus expose themselves to sexually transmitted infections and other risks. CONCLUSION: University sexual risk reduction programs should be developed considering the specific cultural context, using strategies that empower young men to challenge the widely accepted cultural norms that may predispose them to sexual risks. Sexual behaviours and cultural norms are interconnected, it is through culture that people learn how to behave and understand the world around them. In many cultural contexts, young men are taught from a very young age how to behave based on dominant notions of what it means to be a man in that particular context. As such, in some cultural context sexual risk-taking such as having multiple sexual partners and unprotected sex are perceived as normal behaviour for men. Some young men embrace such normalised sexual behaviours which often has negative implications on their future. This study explored the influence of cultural norms on the sexual behaviour of young men. This qualitative study was conducted at the University of KwaZulu-Natal. Four focus group discussions were conducted among first-year students to postgraduate students who were between the ages of 18 to 30 years. Our findings revealed that there other influences on the sexual behaviours of the young men, which included family, community and peers. It also emerged that gender norms regarding what it means to be a man still prevailed which some of the young men in the study adhered to, notably such notions seemed to be rejected by some of them. The university setting appeared to be space where a lot of sexual risk-taking took place, which potentially exposed the young men in the study to many sexual risks. In conclusion, targeted programs for the university setting should aim to challenge gender norms that expose young men to sexual risks.

Socio-demographic and behavioural profile of women in polygamous relationships in South Africa: a retrospective analysis of the 2002 population-based household survey data.

BACKGROUND: The prevalence and effect of polygamous relationships may have serious reproductive and /or health consequences for women. In South Africa, unlike in other sub-Saharan countries, no nationwide survey has investigated polygamy except for the 2002 HIV/AIDS population-based household survey. The aim of this study was to profile socio-demographic and behavioural characteristics associated with women in polygamous relationships in South Africa using the 2002 survey data. METHODS: The survey data were collected using a multi-stage stratified cluster randomised sampling design. Bivariate and multivariate logistic regression models were used to assess the relationship between polygamy, and selected socio-demographic and behavioural factors. RESULTS: Of 1437 women who responded to the question on polygamy, 8.3% reported being in a polygamous marriage. Women in polygamous marriages were significantly less likely to have tertiary education [OR = 0.03(95% CI: 0.00-0.28), p = 0.003], to have money for food and clothes [OR = 0.12 (95% CI: 0.06-0.27), p < 0.001], to have a sexual partner five years younger [OR = 0.10 (95% CI: 0.01-0.94), p = 0.044] or sexual partner within 5 years older or younger [OR = 0.35 (95% CI: 0.13-0.991), p = 0.032]. They were also significantly more likely to have two or more sexual partners [OR = 20.42 (95% CI: 1.10-379.89), p = 0.043]. CONCLUSION: The finding that polygamy is associated with uneducated and women of low economic means, who have relationships with older men and multiple sexual partners warrants further attention. Contemporary studies on polygamy are needed in South Africa.

Determinants of HIV infection among adolescent girls and young women aged 15-24 years in South Africa: a 2012 population-based national household survey.

BACKGROUND: South Africa is making tremendous progress in the fight against HIV, however, adolescent girls and young women aged 15-24 years (AGYW) remain at higher risk of new HIV infections. This paper investigates socio-demographic and behavioural determinants of HIV infection among AGYW in South Africa. METHODS: A secondary data analysis was undertaken based on the 2012 population-based nationally representative multi-stage stratified cluster random household sample. Multivariate stepwise backward and forward regression modelling was used to determine factors independently associated with HIV prevalence. RESULTS: Out of 3092 interviewed and tested AGYW 11.4% were HIV positive. Overall HIV prevalence was significantly higher among young women (17.4%) compared to adolescent girls (5.6%). In the AGYW model increased risk of HIV infection was associated with being young women aged 20-24 years (OR = 2.30, p = 0.006), and condom use at last sex (OR = 1.91, p = 0.010), and decreased likelihood was associated with other race groups (OR = 0.06, p < 0.001), sexual partner within 5 years of age (OR = 0.53, p = 0.012), tertiary level education (OR = 0.11, p = 0.002), low risk alcohol use (OR = 0.19, p = 0.022) and having one sexual partner (OR = 0.43, p = 0.028). In the adolescent girls model decreased risk of HIV infection was associated with other race groups (OR = 0.01, p < 0.001), being married (OR = 0.07), p = 0.016], and living in less poor household (OR = 0.08, p = 0.002). In the young women's models increased risk of HIV infection was associated with condom use at last sex (OR = 2.09, p = 0.013), and decreased likelihood was associated with other race groups (OR = 0.17, p < 0.001), one sexual partner (OR = 0.6, p = 0.014), low risk alcohol use (OR = 0.17, p < 0.001), having a sexual partner within 5 years of age (OR = 0.29, p = 0.022), and having tertiary education (OR = 0.29, p = 0.022). CONCLUSION: 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.

Proliferative capacity and cytokine production by cells of HIV-infected and uninfected adults with different helminth infection phenotypes in South Africa.

BACKGROUND: It has been suggested that the proliferative capacity of cells from individuals with HIV or both HIV and helminth infections is attenuated and cytokine production is dysregulated. This study describes peripheral blood mononuclear cell proliferation capacity and cytokine profile from individuals with HIV or both HIV and helminth infections in South Africa. METHODS: Forty HIV-infected and 22 HIV-uninfected participants were randomly selected and stratified into different helminth infection phenotypes by egg excretion and Ascaris lumbricoides specific -immunoglobulin-E (IgE) levels. Five day cell cultures of participants, unstimulated or stimulated with Phytohaemaglutinnin, Streptokinase, HIV-1 p24 and Ascaris lumbricoides worm antigens were stained with monoclonal antibody-fluorochrome conjugates (Ki67-FITC and CTLA-APC-4). Percentage expression of Ki67 and CTLA-4 was measured to determine cell proliferation and regulation, respectively. Culture supernatants were analysed for the expression of 13 cytokines using the Bioplex (BioRad) system. Kruskal Wallis was used to test for differences in variables between helminth infected subgroups who were either having eggs in stool and high IgE (egg+IgEhi); or eggs in stool and low IgE (egg+IgElo); or no eggs in stool and high IgE (egg-IgEhi) and those without helminth infection (egg-IgElo). RESULTS: Individuals excreting eggs in stool with high serum IgE (egg+IgEhi phenotype) had potent mitogen responses but consistently produced low, but statistically non-significant antigen-specific (HIV-1 p24 (p = 0.41) and Ascaris (p = 0.19) and recall antigen (Streptokinase; p = 0.31) Ki67 responses. The group also had reduced type 1 cytokines. Individuals excreting eggs in stool with low serum IgE( egg+IgElo phenotype) had a more favourable antiviral profile, characterized by higher IFNγ, IL-2, lower IL-4 and higher IL-10 production. CONCLUSION: The findings suggest that dual HIV/helminth infection with egg excretion and/or high Ascaris IgE phenotye may be linked with poor proliferative capacity and deleterious cytokine profile with regards to HIV control.

Prevalence and factors associated with external HIV-related stigma in the South African population: Results from the 2017 population-based household survey.

External HIV-related stigma remains pervasive, and its effect debilitating among PLHIV in South Africa, even though the country has made many advances against HIV. External HIV-related stigma impedes both HIV prevention and access to health care and reduces the quality of treatment and care received. This study examined the prevalence of and factors associated with higher levels of HIV-related stigma among youth and adults 15 years and older in South Africa. The analysis used a nationally representative population-based household survey data collected using a multistage cluster random sampling design. Exploratory factor analysis was used to calculate the primary outcome (higher and lower HIV stigma index scores above and below the mean, respectively), based on the total number of factors retained from the 10 item self-reported questions relating to attitudes and beliefs against PLHIV. Bivariate and multivariate generalised linear models with a log link and binomial distribution were fitted to estimate crude and adjusted risk ratios (ARR) with 95% confidence intervals (CI) for factors associated with external HIV-related stigma. Of 38 919 respondents, 49% (49.8%; 95% CI: 48.6-51.1) were categorised as having higher levels of external HIV-related stigma. Higher levels of HIV-related stigma were significantly associated with those who had secondary level education than those with no education/primary education [ARR = 1.14 (95% CI: 1.05-1.24), p = 0.002], those employed than unemployed [ARR = 1.08 (95% CI: 1.02-1.14), p = 0.006], those in rural areas than urban areas [ARR = 1.15 (95% CI: 1.07-1.23), p<0.001], those who were aware of their HIV status than not aware [ARR = 1.34 (95% CI: 1.12-1.61), p<0.001], those who were HIV positive than HIV negative [ARR = 1.09 (95% CI: 1.02-1.17), p = 0.018], and those with no correct HIV knowledge and myth rejection than their counterparts [ARR = 1.09 (95% CI: 1.03-1.15), p = 0.002]. The findings highlight the need for peer-facilitated HIV-stigma reduction interventions targeting all types of educational institutions and the strengthening of work-based interventions. The findings emphasise the prioritisation of rural informal settings/tribal areas when developing and implementing HIV stigma reduction interventions. The study suggests that stigma reduction should be considered an important component of HIV testing and awareness. Addressing public misconceptions about HIV can mitigate externalised stigma.

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.
