Concerns about contracting HIV, knowing partners' HIV sero-status and discussion of HIV/STI with sexual partners as determinants of uptake of HIV testing

Pooled prevalence, spatial variation and associated factors of HIV testing uptake among multiple sexual partners in Sub Saharan Africa: Spatial and multilevel analysis

BACKGROUND

Uptake of HIV testing is vital for the early diagnosis of HIV infection and initiation of treatment, which are used to eliminate the disease's progression and reduce HIV-related mortality. Even if determining HIV testing is imperative to prevent HIV/AIDS among multiple sexual partners who are at higher risk of sexually transmitted infections, most of the countries in Sub Saharan Africa did not fulfil the global targets of UNAIDS. Moreover there is a paucity of literature on spatial variation and factors associated with HIV testing among high-risk groups in SSA. This study aimed to assess the pooled prevalence, spatial variation and determinants of HIV testing uptake among multiple sexual partners in Sub Saharan Africa.

METHODS

The Demographic and Health Surveys data conducted between 2011 and 2021 in 30 Sub-Saharan Africa countries was used to analyze total weighted sample of 56,210 multiple sexual partners. Exploratory spatial data analysis, with countries as the unit of analysis was conducted using ArcGIS V10.7.1 and Sat Scan V 10.1 soft wares. A multilevel binary logistic regression model was used to identify the factors associated with the HIV testing uptake. The Adjusted odds Ratio with a 95% confidence interval was reported to declare the strength of association and their statistical significance.

RESULTS

The spatial patterns of HIV testing uptake were found to be non-random. Primary clusters were identified around western and central sub- regions. Multiple sexual partners who were ever married, those attended primary level and above education, those from rich wealth status, aged above 24 years, having good HIV related knowledge, and exposed to media were positive association with HIV testing uptake. However, being male, having working status and living in rural area were negatively associated with HIV testing uptake. At the community-level, multiple sexual partners from communities in Eastern and southern sub regions, countries with upper middle income and countries with the survey year after 2014 were more likely to utilize HIV testing services compared with their counterparts.

CONCLUSION

In this study, the pooled prevalence of the HIV testing uptake among multiple sexual partners was found to be lower than the universal target and showed differences in HIV testing uptake across Sub-Saharan Africa region. Both individual and community-level factors affected HIV testing uptake among multiple sexual partners. Stakeholders should implement interventions to help increase the uptake of HIV testing among those risky groups in this region.

Determinants of preventive sexual behaviours among first year university students in Beira city, central Mozambique: a cross-sectional study

BACKGROUND

Understanding determinants of preventive sexual behaviours is important for intervention efforts to support these behaviours and, thereby, reduce STIs and HIV burden. In general, there is limited insight into determinants of preventive behaviours among university students in Mozambique. Therefore, this study set out to assess both the prevalence and the determinants of condom use and voluntary counselling and testing (VCT) service use in first year university students.

METHODS

We conducted a cross-sectional study in May-September 2021, at the Universidade Católica de Moçambique and the Universidade Licungo, in Beira central Mozambique. We collected data on sociodemographic characteristics, heterosexual relationship experiences and personal determinants posited to be associated with condom use and VCT service use. We included 819 participants, who were selected using a clustered and random sampling design. We used Pearson's chi-square test to compare proportion and estimate the crude odd ratio as the effect size measure at 95% confidence interval, and Confidence Interval-Based Estimation of Relevance to determine correlation coefficients of means and the behaviours of interest at 95% confidence interval.

RESULTS

Condoms were used by 96.1% of male participants and 95.0% of female participants. Additionally, 55.1% of male participants and 57.5% of female participants had previously used VCT services. Condom use was associated with discussing sexuality with mother, and self-efficacy for condom use negotiation, and negatively associated with attitudes that condoms reduce pleasure. VCT service use was associated with discussing sexuality with mother, sexual debut, having a sexual partner, and being in what they consider an important heterosexual relationship. Knowledge, attitude, self-efficacy and subjective norms were weakly associated with VCT service use.

CONCLUSION

In first year university students in Mozambique, reported condom use was high but VCT services were only used by about half of the participants. Interventions aiming to increase VCT service use should focus on improving communication between parents and their adolescent or young adult children, providing personalized risk information, demonstrating that VCT service use is pleasant and non-judgmental, improving users' confidence to schedule a visit, and preparing users for possible positive testing results.

Estimation of HIV-1 Incidence Using a Testing History-Based Method; Analysis From the Population-Based HIV Impact Assessment Survey Data in 12 African Countries

BACKGROUND

Estimating HIV incidence is essential to monitoring progress in sub-Saharan African nations toward global epidemic control. One method for incidence estimation is to test nationally representative samples using laboratory-based incidence assays. An alternative method based on reported HIV testing history and the proportion of undiagnosed infections has recently been described.

METHODS

We applied an HIV incidence estimation method which uses history of testing to nationally representative cross-sectional survey data from 12 sub-Saharan African nations with varying country-specific HIV prevalence. We compared these estimates with those derived from laboratory-based incidence assays. Participants were tested for HIV using the national rapid test algorithm and asked about prior HIV testing, date and result of their most recent test, and date of antiretroviral therapy initiation.

RESULTS

The testing history-based method consistently produced results that are comparable and strongly correlated with estimates produced using a laboratory-based HIV incidence assay (ρ = 0.85). The testing history-based method produced incidence estimates that were more precise compared with the biomarker-based method. The testing history-based method identified sex-, age-, and geographic location-specific differences in incidence that were not detected using the biomarker-based method.

CONCLUSIONS

The testing history-based method estimates are more precise and can produce age-specific and sex-specific incidence estimates that are informative for programmatic decisions. The method also allows for comparisons of the HIV transmission rate and other components of HIV incidence among and within countries. The testing history-based method is a useful tool for estimating and validating HIV incidence from cross-sectional survey data.

HIV testing uptake and determinants among adolescents and young people in Burundi: a cross-sectional analysis of the Demographic and Health Survey 2016-2017

OBJECTIVES

To assess HIV testing uptake and its determinants among adolescents and young adults.

DESIGN

Cross-sectional design involving analysis of 2016 Demographic and Health Survey data.

SETTING

Nationally representative survey of Burundi.

PARTICIPANTS

A total of 7218 young women and 2860 young men were included.

PRIMARY AND SECONDARY OUTCOME

We estimated the proportion of adolescent (15-19 years) and young adult (20-24 years) women and men who had tested for HIV and received results in the 12 months preceding the survey. Multivariable logistic models for determining predictors of HIV testing uptake were fitted among respondents aged 15-24 regardless of sexual activity in the 12 months before the survey and separately among a subset that reporting having had sex in the 12 months preceding the survey.

RESULTS

An estimated 27.1% (95% CI 25.8% to 28.4%) women and 16.6% (95% CI 15.1% to 18.1%) men had tested for HIV and received results in the 12 months preceding the survey. The proportion was more than twice as high among those aged 20-24 years compared with 15-19 years, among both sexes. In multivariable analysis, older age (20-24 years) was associated with HIV testing (adjusted OR (aOR): 1.62, 95% CI 1.38 to 1.91) among women; (aOR: 1.78, 95% CI 1.32 to 2.40) among men. Higher educational level (aOR: 1.40, 95% CI 1.11 to 1.76) was significantly associated with HIV testing uptake among women. Male circumcision status, condom use, number of sex partners, history of STIs were not associated with HIV testing among the subset that reported having had sex in the 12 months preceding the survey.

CONCLUSION

Despite the interventions implemented to reach the 90-90-90 UNAIDS goals, HIV testing among youth in Burundi was low. Youth-friendly health centres should be part of strategies to stimulate young people to increase uptake of HIV preventive services in Burundi.

Awareness of HIV serostatus by sex partners of women living with HIV in North-Central Nigeria: correlates and predictive analyses

Non-communication of HIV status among sex partners is a notable hurdle in halting transmission, largely due to socio-cultural factors. This study aimed to predict the determinants of male partners' awareness of women's serostatus. A total of 8825 women of reproductive age living with HIV who were clients at five comprehensive HIV treatment centres in Benue State, North-Central Nigeria were surveyed between June and December 2017, and 6655 reported having a sexual partner at the time of the survey selected for analysis. A regression model was used to estimate the determinants of male partner awareness of serostatus from the perspective of women. Conditional marginal analyses were conducted to evaluate the marginal effects of identified predictors on the probability of outcomes. Partners of married women were found to have greater odds of being aware of their spouse's serostatus (adjusted OR (aOR): 3.20; 95%CI: 2.13-4.81) than non-married partners. Similarly, the odds of male partner awareness increased with the years women had been on antiretroviral therapy (aOR: 1.13; 95%CI: 1.07-1.20). The probability of partners of married respondents being aware of their spouse's HIV serostatus was 97%. The conditional marginal effects of being educated to primary or higher level were 1.2 (95% CI: -0.2 to 2.7) and 1.8 (95% CI: 0.09-3.4) percentage points higher respectively when compared with women with no formal education. Being unemployed or being a trader significantly decreased the probability of partners being aware of respondents' serostatus when compared with farmers; conditional marginal effects of -6.7 (95% CI: -12.0 to -1.4) and -3.9 (95% CI: -5.7 to -2.2) percentage points, respectively. The study found that relationship status and girl-child education are factors that can improve communication of HIV status to sex partners. Policies and interventions aimed at improving the social determinants of health, and social support for healthy communications in relationships, are recommended to reduce HIV transmission between sex partners.

Distance as explanatory factor for sexual health centre utilization: an urban population-based study in the Netherlands

Background

The central sexual health centre (SHC) in the greater Rotterdam area in the Netherlands helps finding people unaware of their STI/HIV status. We aimed to determine a possible association between SHC utilization and travel distance in this urban and infrastructure-rich area. Insight in area-specific utilization helps adjust outreach policies to enhance STI testing.

Methods

The study population consists of all residents aged 15–45 years in the greater Rotterdam area (2015–17). We linked SHC consultation data from STI tested heterosexual clients to the population registry. The association between SHC utilization and distance was investigated by multilevel modelling, adjusting for sociodemographic and area-specific determinants. The data were also stratified by age (aged < 25 years) and migratory background (non-Western), since SHC triage may affect their utilization. We used straight-line distance between postal code area centroid and SHC address as a proxy for travel distance.

Results

We found large area variation in SHC utilization (range: 1.13–48.76 per 1000 residents). Both individual- and area-level determinants determine utilization. Travel distance explained most area variation and was inversely associated with SHC utilization when adjusted for other sociodemographic and area-specific determinants [odds ratio (OR) per kilometre: 0.95; 95% confidence interval (CI): 0.93–0.96]. Similar results were obtained for residents <25 years (OR: 0.95; 95% CI: 0.94–0.96), but not for non-Western residents (OR: 0.99; 95% CI: 0.99–1.00).

Conclusions

Living further away from a central SHC shows a distance decline effect in utilization. We recommend to enhance STI testing by offering STI testing services closer to the population.

HIV testing and self-testing coverage among men and women in South Africa: an exploration of related factors

OBJECTIVES

Uptake of HIV testing is critical to halting the spread of HIV. Our study aimed to examine the coverage of HIV testing and self-testing and the individual-level, household-level and community-level factors associated with HIV testing and self-testing awareness.

METHODS

We analysed data of 12 312 men and women from 2016 SADHS and used multilevel mixed-effects models to examine the factors associated with uptake of HIV testing and self-testing awareness.

RESULTS

About 80% of participants had ever tested for HIV, and 64% had tested in the past year. Only 49% of adolescents aged 15-19 years had ever tested for HIV compared with over 80% of adults. Self-testing awareness was low (22%), and only 2.9% of respondents had ever self-tested for HIV. The odds of having ever tested for HIV were significantly higher among respondents who were aged 25-29 (AOR: 4.02; 95% CI: 3.27-4.95), had a higher level of education (AOR: 3.18; 95% CI: 2.19-4.61), were married (AOR: 1.63; 95% CI: 1.36-1.94), had high media exposure (AOR: 1.23; 95% CI: 1.06-1.44) and had ever had sex (AOR: 5.57; 95% CI: 4.67-6.64), but lower among men (AOR: 0.39; 95% CI: 0.35-0.44).

CONCLUSION

In conclusion, HIV testing coverage is high in South Africa relative to most countries in sub-Saharan Africa, but falls short of the UNAIDS first 95. We found no evidence of socioeconomic and geographic inequalities in access to HIV testing. However, adolescents had a lower level of HIV testing uptake, suggesting a need for interventions to expand testing in this age group.

Feasibility and acceptability of a pilot, peer-led HIV self-testing intervention in a hyperendemic fishing community in rural Uganda

Background

Novel interventions are needed to reach young people and adult men with HIV services given the low HIV testing rates in these population sub-groups. We assessed the feasibility and acceptability of a peer-led oral HIV self-testing (HIVST) intervention in Kasensero, a hyperendemic fishing community (HIV prevalence: 37–41%) in Rakai, Uganda.

Methods

This study was conducted among young people (15–24 years) and adult men (25+ years) between May and August 2019. The study entailed distribution of HIVST kits by trained “peer-leaders,” who were selected from existing social networks and trained in HIVST distribution processes. Peer-leaders received up to 10 kits to distribute to eligible social network members (i.e. aged 15–24 years if young people or 25+ years if adult man, not tested in the past 3 months, and HIV-negative or of unknown HIV status at enrolment). The intervention was evaluated against the feasibility benchmark of 70% of peer-leaders distributing up to 70% of the kits that they received; and the acceptability benchmark of >80% of the respondents self-testing for HIV.

Results

Of 298 enrolled into the study at baseline, 56.4% (n = 168) were young people (15–24 years) and 43.6% (n = 130) were adult males (25+ years). Peer-leaders received 298 kits and distributed 296 (99.3%) kits to their social network members. Of the 282 interviewed at follow-up, 98.2% (n = 277) reported that they used the HIVST kits. HIV prevalence was 7.4% (n = 21). Of the 57.1% (n = 12) first-time HIV-positives, 100% sought confirmatory HIV testing and nine of the ten (90%) respondents who were confirmed as HIV-positive were linked to HIV care within 1 week of HIV diagnosis.

Conclusion

Our findings show that a social network-based, peer-led HIVST intervention in a hyperendemic fishing community is highly feasible and acceptable, and achieves high linkage to HIV care among newly diagnosed HIV-positive individuals.

Low coverage of HIV testing among adolescents and young adults in Nigeria: Implication for achieving the UNAIDS first 95

Background

Most studies on HIV testing among young people in Nigeria are not nationally representative. As such, recent nationally representative data, such as the Multiple Indicator Cluster Survey (MICS), could help assess the current level of HIV testing among young people, a key target population for HIV prevention in the country. In this study, we examined the coverage and factors associated with HIV testing among adolescents and young adults (AYA).

Methods

We used the data for 14,312 AYA that examined recent and lifetime HIV testing from the 2017 MCIS. Our outcomes of interest were ever tested for HIV and recently tested for HIV. We examined the association between socio-demographic factors (e.g., age, marital status, education attainment, wealth status), stigma belief, exposure to media and HIV knowledge, and uptake of HIV testing using adjusted and unadjusted logistic regression models.

Results

Less than a quarter of the AYA (23.7%) had ever tested for HIV, and an even lower proportion (12.4%) tested in the year preceding the survey. More females (25.4%) compared to males (20.8%) had ever tested for HIV. Young people who were aged 20–24 years (AOR 1.52, 95% CI 1.34–1.72), married (AOR 2.42, 95% CI 1.98–2.97), had higher educational attainment (AOR 5.85, 95% CI 4.39–7.81), and belonged to the wealthiest quintile (AOR 1.99, 95% CI 1.53–2.60), had higher odds of having ever tested for HIV compared to those aged 15–19 years, never married, had no formal education and belonged to the poorest wealth quintile. Also, those who had positive stigma belief towards people living with HIV (AOR 2.93, 95% CI 2.47–3.49), had higher HIV knowledge (AOR 1.62, 95% CI 1.24–2.11), and higher media exposure (AOR 1.64, 95% CI 1.36–1.97), had higher odds of having ever tested compared to those who had more negative stigma belief, had low knowledge of HIV and low media exposure.

Conclusion

The HIV testing coverage among AYA in Nigeria is well below the national target of 95% indicated in the national HIV/AIDS strategic framework (2017–2021). Also, the low rate of HIV testing found in this study means realising the UNAIDS first 95 will require interventions targeting AYA. These interventions should focus on improving young people's knowledge of HIV, reducing negative stigma belief through media campaigns and increasing access to HIV testing through home-based testing and "opt-out" strategy at the point of care.

Achieving the first of the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets: understanding the influence of HIV risk perceptions, knowing one's partner's status and discussion of HIV/sexually transmitted infections with a sexual partner on uptake of HIV testing

This study assessed how HIV risk perceptions, knowledge of one's partner's status and discussion of HIV/sexually transmitted infections (STIs) with one's sexual partner influence the uptake of HIV testing. Data were obtained from 833 young adults, selected using stratified random sampling in a South African university in 2018. Adjusted and unadjusted logistic regression models were employed to examine determinants of HIV testing uptake. The majority of students (69.9%) had previously tested for HIV, but only 58.4% tested for HIV in the last year. Being highly concerned about contracting HIV/STIs was positively associated with having tested for HIV (adjusted OR [AOR]: 4.28; CI: 2.50 to 7.34) and getting an HIV test in the past year (AOR: 1.83; CI: 1.20 to 2.80). Knowing one's partner's status was associated with a higher probability of ever having been tested for HIV (AOR: 3.07; CI: 1.89 to 4.97) or having received an HIV test in the previous year (AOR: 2.66; CI: 1.77 to 3.99). Discussion of HIV/STIs was associated with higher odds of having ever been tested for HIV (AOR: 3.81; CI: 2.44 to 5.96) and recent HIV testing (AOR: 3.22; CI: 2.17 to 4.77). HIV testing was below the Joint United Nations Programme on HIV/AIDS UNAIDS 90-90-90 target. Being concerned about contracting HIV, discussion of HIV/STIs with a sexual partner and knowing one's partner's HIV status were associated with the uptake of HIV testing.

Low awareness and use of pre-exposure prophylaxis among adolescents and young adults in high HIV and sexual violence prevalence settings

South Africa has adopted pre-exposure prophylaxis (PrEP) as a preventive strategy for populations at-risk for HIV, though uptake is low among adolescents and young adults. We examined the awareness and use of PrEP among adolescents and young adults in the Eastern Cape, South Africa.This cross-sectional study was conducted between June and November 2018 among 772 adolescents and young adults (aged 16-24 years) selected using stratified random sampling in a South African university. An electronic self-administered questionnaire was used to elicit demographic information, behavioral, family-related characteristics, awareness and use of PrEP. Adjusted and unadjusted logistic regression models were used to examine the predictors of PrEP awareness.The overall level of PrEP awareness was 18.8%; however, only 1.7% of participants had used PrEP, 7.5% of had seen it, 4.8% knew how much it cost, and 14.8% knew where and how to get it. In the adjusted regression analysis, only adequate family support (AOR: 2.11; CI: 1.47-3.04) and discussions of HIV and sexually transmitted infections with sexual partners (AOR: 1.78; CI: 1.19-2.67) were associated with a higher likelihood of being aware of PrEP.The level of awareness and use of PrEP is still very low among adolescents and young adults who may need it to prevent HIV infection. Poor awareness of PrEP among adolescents and young adults in high HIV risk settings may limit its use. Thus, concerted efforts are needed to promote awareness and access to PrEP among young South African adults.

Factors associated with consistent condom use: a cross-sectional survey of two Nigerian universities

Background

Consistent condom use is central to the prevention of transmission of human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs), especially among young adults. This study drew from a cross-sectional survey of two Nigerian universities to determine the level of consistent condom use, explored the determinants of condom use consistency and reasons for inconsistent condom use.

Methods

We adopted a descriptive cross-sectional design, which involves the recruitment of 800 male and female students using stratified random sampling. Adjusted and unadjusted logistic regression models were used to examine the factors associated with consistent condom use among a final sample of 498 students who engaged in sex in the last year preceding the study.

Results

Only 38.6% of sexually active participants (n = 498) used condoms consistently in the previous year. High condom self-efficacy score (AOR: 2.40; 95% CI: 1.58–3.64), discussion of HIV/STIs with sexual partner (AOR: 1.91; 95%CI: 1.29–2.83), knowing partner’s HIV status (AOR: 1.48; 95% CI: 1.02–2.16), being students of university located in a high HIV prevalence area (AOR: 2.86; 95% CI: 1.92–4.28) and engaging in sex with only steady partner (AOR: 1.74; 95% CI: 1.17–2.60) were associated with a higher odds of consistent condom use. Trust, unavailability of condoms, dislike of condoms and a perception that condoms reduced sexual pleasure were the main reasons for inconsistent use of condoms.

Conclusion

The study found a low level of consistent condom use among study participants. Counselling young adults in Nigeria on condom self-efficacy, providing condoms on campuses and encouraging the discussion of sexually transmitted infections with sexual partners are central to improving the level of consistent condom use among Nigerian university students.

Protective sexual behaviours among young adults in Nigeria: influence of family support and living with both parents

Background

Many studies have focused on risky sexual behaviour among adolescents and young adults; however, literature on protective sexual practices among this age cohort is still evolving. Since young adults are disproportionately burdened by sexually transmissible infections, including HIV, understanding factors that influence protective sexual behaviour among the age group is crucial in developing age-appropriate interventions. Drawing from a cross-sectional survey conducted among adolescents and young adults in two Nigerian universities, we examined gender differences in protective sexual behaviours and the influence of family support and living with both parents on these behaviours.

Methods

A total of 800 male and female university students in two Nigerian universities were recruited using stratified random sampling between February and April 2018. Analysis was, however, based on 599 participants aged between 15 and 24 . Adjusted and unadjusted multinomial logistic regression models were used to examine the influence of family support, and living with both parents on protective sexual behaviours at a 95% confidence interval.

Results

Findings show that the largest proportion of our participants engaged in protective sexual behaviours. We found no gender differences in protective sexual behaviours, including sexual abstinence, consistent condom use, and sexual fidelity. Family support and living with both parents were positively associated with protective sexual behaviours among adolescents and young adults.

Conclusion

This study found that a majority of adolescents and young adults in Nigerian Universities engage in protective sexual behaviours. Adequate family support and living with both parents are positively associated with protective sexual behaviours. The study however revealed that about one-fifth of our participants engaged in high-risk sexual behaviour. This suggests a need for behavioural change interventions, provision of sexual health services and empowerment of students who receive inadequate family support.
