The HIV care continuum for sexually active transgender women in three metropolitan municipalities in South Africa: findings from a biobehavioural survey 2018-19

BACKGROUND

Despite high HIV prevalence in transgender women in sub-Saharan Africa, to our knowledge no study presents data across the HIV care continuum for this population in the region. The aim of this study was to estimate HIV prevalence and present data to develop the HIV care continuum indicators for transgender women in three South African metropolitan municipalities.

METHODS

Biobehavioural survey data were collected among sexually active transgender women in the metropolitan municipalities of Johannesburg, Buffalo City, and Cape Town, South Africa. Transgender women (aged ≥18 years, self-reporting consensual sex with a man in the 6 months before the survey) were recruited using respondent-driven sampling (RDS). An interviewer-administered questionnaire was used to determine awareness of HIV status; blood specimens were collected on dried blood spots to test for HIV antibodies, antiretroviral treatment (ART) exposure, and viral load suppression. Population-based estimates of HIV 95-95-95 cascade indicators were derived by use of individualised RDS weights with RDS Analyst software. Multivariate stepwise backward logistic regression modelling was used to determine factors associated with each cascade indicator. All eligible participants were included in the final analysis.

FINDINGS

Between July 26, 2018, and March 15, 2019, we enrolled 887 sexually active transgender women: 323 in Johannesburg, 305 in Buffalo City, and 259 in Cape Town. HIV prevalence was highest in Johannesburg where 229 (74·1%) of 309 tests were positive (weighted prevalence estimate 63·3%, 95% CI 55·5-70·5), followed by Buffalo City where 121 (43·7%) of 277 were positive (46·1%, 38·7-53·6), and then Cape Town where 122 (48·4%) of 252 were positive (45·6%, 36·7-54·7). In Johannesburg, an estimated 54·2% (95% CI 45·8-62·4) of transgender women with HIV knew their positive status, in Cape Town this was 24·2% (15·4-35·8), and in Buffalo City this was 39·5% (27·1-53·4). Among those who knew their status, 82·1% (73·3-88·5) in Johannesburg, 78·2% (57·9-90·3) in Cape Town, and 64·7% (45·2-80·2) in Buffalo City were on ART. Of those on ART, 34·4% (27·2-42·4) in Johannesburg, 41·2% (30·7-52·6) in Cape Town, and 55·0% (40·7-68·4) in Buffalo City were virally suppressed.

INTERPRETATION

Innovative strategies are needed to inform efforts to diagnose and to treat transgender women living with HIV promptly to achieve viral load suppression. Differentiated HIV services tailored to transgender women of race groups other than Black South African, and those with low education attainment and low outreach exposure, innovative testing, and adherence strategies should be developed to improve the HIV cascade for South African transgender women.

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 pretested structured questionnaire was administered to a consented sample of barbers sampled using a multistage random sample design. Descriptive and inferential statistics were performed using Stata version 14.0 software programme where 0.05 level was used as a measure of significance. The knowledge level of the barbers regarding HIV/AIDS was inadequate (63.6%). Knowledge was significantly associated with work experience [AOR = 13.56 (95% CI: 2.73-67.25); p = 0.001], with attitude [AOR = 4.07 (95% CI: 1.27-13.08); p = 0.018], with level of education [AOR = 10.22 (95% CI: 2.24-46.64); p = 0.003], with marital status [AOR = 0.07 (95% CI: 0.01-0.50); p = 0.008] and with number of clients per day [AOR = 0.13 (95% CI: 0.03-0.52); p = 0.004]. The attitude of barbers was also inadequate (58.7%). Attitude was significantly associated with the mode of learning the barbing profession [AOR = 0.32 (95% CI: 0.11-0.89); p = 0.029], and with level of knowledge [AOR = 5.48 (95% CI: 2.01-14.93); p = 0.001]. Majority of the participants exhibited poor prevention practices regarding HIV/AIDS (87.6%). Prevention practice was significantly associated with work experience [AOR = 24.92 (95% CI: 2.08-297.86); p = 0.011] and with level of knowledge [AOR = 12.57 (95% CI: 1.35-116.86); p = 0.026]. The barbers in Ho exhibited inadequate knowledge and attitude regarding HIV/AIDS, and also manifested poor prevention practices regarding HIV/AIDS. Programmes aimed at improving the knowledge, attitudes and prevention practices should be implemented among barbers, with focus on those without any formal education, those with less than five years work experience and those with more than ten clients a day.

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.

"It Had a Lot of Cultural Stuff in It": HIV-Serodiscordant African American Couples' Experiences of a Culturally Congruent Sexual Health Intervention

Objective

The increased life expectancy of people living with HIV has brought about an increase in serodiscordant couples, in which there is risk of HIV transmission. Therefore, interventions that promote sexual health and reduce risk are critical to develop for these couples. Given the disproportionate burden of HIV among populations of color, it is also critical that these interventions are culturally congruent. The EBAN intervention for African American serodiscordant couples recognizes the centrality of culture in shaping sexual behaviors and helps couples develop intimacy and positive prevention behaviors. The analytic objective of our study was to examine the knowledge and awareness gained by participants in the intervention.

Participants

Participants (n=17) who completed at least half of the eight intervention sessions.

Methods

Brief post-implementation semi-structured interviews were conducted between January 1, 2016 and December 31, 2016. Team-based, targeted content analysis focused on knowledge and awareness gains.

Results

Participants described learning about sexual health, expanded sexual options, and sexual communication. The "EBAN café," a component that gives couples a menu of options for safer sex behaviors, was particularly popular. Participants also noted the value of learning how to communicate with one another about their sexual health-related concerns and preferences. They appreciated the "cultural stuff" that was infused throughout the sessions, including the emphasis on learning from one another as couples.

Conclusions

Couples at risk for HIV transmission benefit from strengthening skills and knowledge related to healthy sexuality. A behavioral intervention that aligns with cultural values and imparts culturally congruent sexual health information appeals to couples who seek ways to enhance their intimacy and sexual options while also reducing risk.

HIV risks associated with patronizing alcohol serving establishments in South African Townships, Cape Town

Alcohol use has been closely linked with HIV risk behaviors in South Africa. The places where people drink are often the same settings in which they meet new sex partners and may contribute independently to sexual risk. This current study examines the independent effects of patronizing alcohol serving establishments (shebeens) and alcohol use in predicting HIV risk behaviors. Men (n = 981) and women (n = 492) were recruited from inside shebeens and surrounding areas proximal to shebeens in eight separate neighborhoods in a Township in Cape Town, South Africa. Anonymous community surveys measured demographic characteristics, alcohol use, shebeen attendance, and sexual risk behaviors. Comparisons of 1210 (82 %) participants who patronized shebeens in the past month with 263 (18 %) participants who did not patronize shebeens demonstrated higher rates of alcohol use frequency and quantity, more sexual partners, and higher rates of vaginal intercourse without condoms for the patrons. Multiple linear regression analysis found shebeen attendance in the past month predicted greater sexual risk for HIV beyond demographic characteristics and alcohol use. Social influences and environmental factors in shebeens could be contributing to sexual risk behavior independently of alcohol consumption. Further research is needed to understand the environmental factors of shebeens that promote and influence HIV risk behaviors.

Does perceived life stress mediate the association between HIV status and alcohol use? Evidence from adults living in Cape Town, South Africa

South Africa has the highest prevalence of HIV in the world. Because living with HIV is stressful and because alcohol consumption is often used to cope with stress, we examined whether stress mediates the association between HIV status and alcohol use among adults residing in South African townships. Field workers approached pedestrians or patrons of informal alcohol-serving venues (i.e., shebeens) and invited their participation in a survey. Of the 1717 participants (98% Black, 34% women, mean age = 31 years), 82% were HIV-negative, 9% were HIV-positive, and 9% did not know their test result. Participants living with HIV reported greater perceived life stress compared to participants whose HIV status was negative or unknown. Perceived stress was associated with an increase in the frequency of alcohol use (drinking days, intoxication, and drinking in shebeens/taverns). Subsequent analyses showed that stress mediated the association between HIV status and alcohol use. These findings indicate that greater frequency of drinking days, perceived intoxication, and drinking at shebeens was associated with elevated stress levels among participants who were HIV positive. Perceived life stress mediates the association between HIV status and alcohol use. Programs to enhance stress management among HIV-positive South Africans may help to reduce alcohol consumption, which may, in turn, lead to reduced rates of HIV transmission.

Impact of HIV testing on sexual health communication in South Africa

OBJECTIVES

The South African government recently launched a national campaign to test 15 million South Africans for HIV by 2011. Little is known about how receipt of HIV testing might influence interpersonal communication. To explore these questions, the authors examined the effects of prior HIV testing on sexual health communication among South Africans.

METHODS

Adults (N=1284; 98% black, 36% women, mean age 31) residing in a South African township completed street-intercept surveys.

RESULTS

Of the 1284 participants, 811 (63%) had been tested for HIV. Among those who had been tested, 77% tested negative, 12% tested positive, and 11% did not know their test result or refused to answer. Compared with those who had not been tested, participants who had been tested for HIV were more likely to communicate with community members about (a) HIV/AIDS, (b) getting tested for HIV, and (c) using condoms. Testing positive for HIV was associated with communication with sexual partners about condom use. Among participants who had been tested for HIV, exploratory analyses revealed that those who had engaged in sexual health communication with community members or sexual partners reported more condom-protected sex than those who had not engaged in sexual health communication.

CONCLUSIONS

HIV testing is associated with sexual health communication among South African community members and sexual partners. Offering HIV testing to all South Africans may increase communication and lead to reductions in sexual risk.

Anopheles arabiensis and An. quadriannulatus resistance to DDT in South Africa

The malaria control programme of KwaZulu-Natal Province, South Africa, includes Mamfene and Mlambo communities. Western-type houses there are currently sprayed with deltamethrin, whereas traditional houses are sprayed with DDT for malaria control. In 2002, mosquitoes of the Anopheles gambiae complex (Diptera: Culicidae) were collected from DDT-sprayed houses, by window exit traps, and from man-baited nets outdoors. Larval collections were also carried out at Mzinweni Pan near Mlambo. Species of the An. gambiae complex were identified by rDNA polymerase chain reaction assay. The majority of samples collected by window trap and baited nets were identified as the malaria vector An. arabiensis Patton, with a few An. merus Dönitz and An. quadriannulatus (Theobald). The larval collections were predominantly An. quadriannulatus with a small number of An. arabiensis. Standard WHO insecticide susceptibility tests using 4% DDT and 0.05% deltamethrin were performed on both wild-caught females and laboratory-reared progeny from wild-caught females. Wild-caught An. arabiensis samples from window traps gave 63% and 100% mortality 24-h post-exposure to DDT or deltamethrin, respectively. Wild-caught An. arabiensis samples from man-baited net traps gave 81% mortality 24-h post-exposure to DDT. The F1 progeny from 22 An. arabiensis females showed average mortality of 86.5% 24-h post-exposure to DDT. Less than 80% mortality was recorded from five of these families. Biochemical analyses of samples from each of the families revealed comparatively high levels of glutathione-S-transferases and non-specific esterases in some families, but without significant correlation to bioassay results. Wild-caught An. quadriannulatus larvae were reared through to adults and assayed on 4% DDT, giving 47% (n = 36) mortality 24-h post-exposure. Finding DDT resistance in the vector An. arabiensis, close to the area where we previously reported pyrethroid-resistance in the vector An. funestus Giles, indicates an urgent need to develop a strategy of insecticide resistance management for the malaria control programmes of southern Africa.

Anopheles funestus resistant to pyrethroid insecticides in South Africa

Northern Kwazulu/Natal (KZN) Province of South Africa borders on southern Mozambique, between Swaziland and the Indian Ocean. To control malaria vectors in KZN, houses were sprayed annually with residual DDT 2 g/ m2 until 1996 when the treatment changed to deltamethrin 20-25 mg/m2. At Ndumu (27 degrees 02'S, 32 degrees 19'E) the recorded malaria incidence increased more than six-fold between 1995 and 1999. Entomological surveys during late 1999 found mosquitoes of the Anopheles funestus group (Diptera: Culicidae) resting in sprayed houses in some sectors of Ndumu area. This very endophilic-vector of malaria had been eliminated from South Africa by DDT spraying in the 1950s, leaving the less endophilic An. arabiensis Patton as the only vector of known importance in KZN. Deltamethrin-sprayed houses at Ndumu were checked for insecticide efficacy by bioassay using susceptible An. arabiensis (laboratory-reared) that demonstrated 100% mortality. Members of the An. funestus group from Ndumu houses (29 males, 116 females) were identified by the rDNA PCR method and four species were found: 74 An. funestus Giles sensu stricto, 34 An. parensis Gillies, seven An. rivulorum Leeson and one An. leesoni Evans. Among An. funestus s.s. females, 5.4% (4/74) were positive for Plasmodium falciparum by ELISA and PCR tests. To test for pyrethroid resistance, mosquito adults were exposed to permethrin discriminating dosage and mortality scored 24h post-exposure: survival rates of wild-caught healthy males were 5/10 An. funestus, 1/9 An. rivulorum and 0/2 An. parensis; survival rates of laboratory-reared adult progeny from 19 An. funestus females averaged 14% (after 1h exposure to 1% permethrin 25:75cis:trans on papers in WHO test kits) and 27% (after 30 min in a bottle with 25 microg permethrin 40:60cis:trans). Anopheles funestus families showing >20% survival in these two resistance test procedures numbered 5/19 and 12/19, respectively. Progeny from 15 of the families were tested on 4% DDT impregnated papers and gave 100% mortality. Finding these proportions of pyrethroid-resistant An. funestus, associated with a malaria upsurge at Ndumu, has serious implications for malaria vector control operations in southern Africa.
