Perceived vulnerability and HIV testing among youth in Cape Town, South Africa

Factors associated with HIV self-testing among female university students in Uganda: a cross-sectional study

BACKGROUND

Adolescent girls and young women (AGYW) at institutions of higher learning are at high risk of HIV, and conventional HIV testing services may not reach them sufficiently. HIV self-testing (HIVST) scalability can be informed by identifying AGYW who have used or are interested in using HIVST. We aimed to determine factors associated with use and willingness to use HIVST among female university students.

METHODS

An online cross-sectional survey was conducted among 483 female students at Makerere University, Uganda. Proportions of students who have used or are willing to use HIVST and their associated factors were determined. Modified Poisson regression models were used to estimate prevalence ratios (PR) and their 95% confidence intervals (CI).

RESULTS

The median age of the participants was 22 (Interquartile range [IQR] 21-23) years, and 21% had never tested for HIV. Over 93% were willing to utilize HIVST, and 19% had ever used HIV self-test kits. Increasing age (adjusted prevalence ratio [aPR] 1.23 per year, 95% CI 1.07-1.43) was significantly associated with HIVST use. Predictors of willingness to self-test for HIV were college type (arts vs. science-based, aPR 0.92, 95% CI 0.88-0.97), number of sexual partners (one, aPR 1.07, 95% CI 1.03-1.12 or ≥ 2, aPR 1.08, 95% CI 1.04-1.19, vs. none), alcohol (aPR 1.04, 95% CI: 1.00-1.09) or injection drug (aPR 1.04, 95% CI 1.00-1.09) use, a history of sexually transmitted infections in past 12 months (aPR 1.05, 95% CI 1.01-1.09), and HIV testing experience (tested in past 12 months, aPR 1.12, 95% CI 1.02-1.22 or over 12 months, aPR 1.13, 95% CI 1.03-1.24, vs. never tested).

CONCLUSION

HIVST was highly acceptable despite its limited use. This study demonstrates female student characteristics that can be leveraged to scale up HIVST programs in higher institutions of learning.

HIV Testing among sexually active Ghanaians: an examination of the rural-urban correlates

HIV testing is critical in reducing the risk of HIV transmission. We investigated the rural-urban correlates of HIV testing amongst sexually active Ghanaians using data from the 2017/2018 Ghana Multiple Indicator Cluster Survey Six (GMICS 6). Robust Poisson models (reporting Adjusted Prevalence Ratios (APR) and 95% Confidence Intervals (CIs)) were used to achieve this aim. About 46% of the participants had ever tested for HIV. According to the results, approximately 52% and 39% of urban and rural dwellers, respectively, have undergone HIV testing. HIV knowledge, HIV stigma, gender, age, education, marital status, childbirth history, sexual history, health insurance coverage, media exposure, household wealth, and region of residence were significantly related to HIV testing with observed variations across rural-urban areas. The findings call for the expansion of advocacy efforts towards encouraging HIV testing, targeting sexually active Ghanaians particularly in rural areas.

Predictors of HIV Testing among Orphaned Youths in Three East African Countries

In parts of sub-Saharan Africa, where HIV prevalence is high, HIV is a leading cause of death among youths. Orphaned and separated youths are an especially vulnerable group, yet we know little about what influences their testing behavior. We conducted multiple logistical regression to examine theory-based predictors of past-year HIV testing among 423 orphaned and separated youths in Ethiopia, Kenya and Tanzania. We also conducted moderation, assessing whether predictors varied by sex. Over one-third of our sample reported past-year HIV testing. Those with greater perceived social support and those who reported sexual HIV risk behavior were more likely to report past-year testing. Furthermore, boys who reported ever previously testing for HIV were more likely, a year later, to report past-year HIV testing. In conclusion, our findings have important implications for intervention development, including the potential for enhanced perceived social support to positively influence HIV testing among orphaned and separated youths.

Relationships between changes in HIV risk perception and condom use in East Zimbabwe 2003-2013: population-based longitudinal analyses

BACKGROUND

Perceiving a personal risk for HIV infection is considered important for engaging in HIV prevention behaviour and often targeted in HIV prevention interventions. However, there is limited evidence for assumed causal relationships between risk perception and prevention behaviour and the degree to which change in behaviour is attributable to change in risk perception is poorly understood. This study examines longitudinal relationships between changes in HIV risk perception and in condom use and the public health importance of changing risk perception.

METHODS

Data on sexually active, HIV-negative adults (15-54 years) were taken from four surveys of a general-population open-cohort study in Manicaland, Zimbabwe (2003-2013). Increasing condom use between surveys was modelled in generalised estimating equations dependent on change in risk perception between surveys. Accounting for changes in other socio-demographic and behavioural factors, regression models examined the bi-directional relationship between risk perception and condom use, testing whether increasing risk perception is associated with increasing condom use and whether increasing condom use is associated with decreasing risk perception. Population attributable fractions (PAFs) were estimated.

RESULTS

One thousand, nine hundred eighty-eight males and 3715 females participated in ≥2 surveys, contributing 8426 surveys pairs. Increasing risk perception between two surveys was associated with higher odds of increasing condom use (males: adjusted odds ratio [aOR] = 1.39, 95% confidence interval [CI] = 0.85-2.28, PAF = 3.39%; females: aOR = 1.41 [1.06-1.88], PAF = 6.59%), adjusting for changes in other socio-demographic and behavioural factors. Those who decreased risk perception were also more likely to increase condom use (males: aOR = 1.76 [1.12-2.78]; females: aOR = 1.23 [0.93-1.62]) compared to those without change in risk perception.

CONCLUSIONS

Results on associations between changing risk perception and increasing condom use support hypothesised effects of risk perception on condom use and effects of condom use on risk perception (down-adjusting risk perception after adopting condom use). However, low proportions of change in condom use were attributable to changing risk perception, underlining the range of factors influencing HIV prevention behaviour and the need for comprehensive approaches to HIV prevention.

HIV risk perception and sexual behaviors among female sex workers in Tehran, Iran

Background: An adequate perception of the degree to which one is at risk of having or contracting HIV is necessary for behavioural change and the adoption of safe behaviours. There are limited data regarding HIV risk perceptions among female sex workers in Iran. This study aimed to determine the HIV risk perception status and its association with sexual behaviours among female sex workers in Tehran. Methods: A cross sectional study was conducted among 170 female sex workers in Tehran. Participants were recruited using a combination of snowball, purposeful, and convenience sampling methods. Multiple logistic regression was used to identify adjusted associations between background factors, sexual behaviours, and HIV risk perception. The analysis was conducted by the "logistf" package in the R statistical system. P-value less than .05 was considered as statistically significant. Results: Among the participants, 122 (77%) reported high HIV risk perception. Most female sex workers with high HIV risk perception reported that they did not consistently use condoms (n=120, 98%. Female sex workers with a higher frequency of sex work (AOR=1.18, 95% CI: 1.08, 1.31), inconsistent condom use (AOR=0.15, 95% CI: 0.02, 0.66), a history of HIV testing (AOR=5.1, 95% CI: 1.2, 26.0), and low HIV knowledge (AOR=0.97, 95% CI=0.95, 0.996) were more likely to report high HIV risk perception. Conclusion: Most female sex workers with risky sexual behaviours had a high HIV risk perception. Effective educational programs are suggested to enable female sex workers to correctly assess their own HIV risk and change risk behaviors based on self-assessment of actual risk.

Youth paying for sex: what are the associated factors? Findings from a cross-sectional study in Cambodia

BACKGROUND

At-risk male youth in Cambodia who purchase sex are at greater risk for HIV compared to the general population. Factors associated with paying for sex among youth are poorly studied, both globally and in Cambodia. This study aimed to identify specific factors associated with transactional sex with women among most-at-risk male youth in Cambodia.

METHODS

This cross-sectional questionnaire survey was conducted with 405 sexually active male youth aged 16-24 recruited at 'hotspots' in the capital city of Phnom Penh and seven provinces. We collected data on demographic factors, sexual behaviors, HIV testing and other potential factors. Multivariable logistic regression analysis was used to identify factors associated with transactional sex.

RESULTS

In total, this study included 405 male youth with a mean age of 21.3 (SD = 2.2). Of the total respondents, 82.5% (n = 334) have ever paid for sex. After controlling for potential confounding, participants who purchased sex in the last 12 months remained significantly more likely to be older than 18 (AOR = 3.60, 95% CI = 1.26-10.62), reside in an urban area (AOR = 2.29, 95% CI = 1.24-4.20), never have been married (AOR = 9.58, 95% CI = 4.34-21.12), spend less than 2.55 USD per day (AOR = 2.22, 95% CI = 1.12-4.40), and have had more than 4.6 sexual partners in the past year (AOR = 16.73, 95% CI = 4.71-59.36).

CONCLUSIONS

This study highlights the high proportion of Cambodian male youth who paid for sex and the potential challenges to addressing this issue. While the majority of HIV prevention interventions surrounding sex work are aimed at female sex workers themselves, targeting the demand side of sex work, particularly the local demand, may be an important next step towards a sustainable HIV prevention.

Modeling Beliefs, Attitudes, and Intentions of Condom Use Among Secondary School Students in Kenya

As in other parts of sub-Saharan Africa, youth in Kenya report low rates of condom use. Although several studies have explored reasons for the low condom use among Kenyan youth, not many have established linkages between lack of use and normative beliefs and attitudes around condoms. Using the Theory of Planned Behavior (TPB), this article examined whether beliefs and attitudes around condoms influenced intentions and actual condom use. Data for the study were restricted to 1453 sexually active youth during the last school break. Path analysis was used to examine the relationship between the TPB constructs and condom use among Kenyan youth. Results indicated a direct relationship between attitudes and condom use for male respondents and an indirect relationship between these two variables for females. Both males and females who expressed greater intentions to use condoms were significantly more likely to report they used condoms consistently. Also, male and female youth with higher perceived behavioral control were significantly more likely to have used condoms consistently. Males with friends who used condoms were significantly more likely to use condoms consistently. The findings suggest the importance of examining young people's attitudes toward condoms-in particular, those deeply rooted in misconceptions that serve to discourage safer sexual behaviors.

Accuracy and determinants of perceived HIV risk among young women in South Africa

BACKGROUND

HIV risk perceptions are a key determinant of HIV testing. The success of efforts to achieve an AIDS-free generation - including reaching the UNAIDS 90-90-90 target - thus depends critically on the content of these perceptions. We examined the accuracy of HIV-risk perceptions and their correlates among young black women in South Africa, a group with one of the highest HIV incidence rates worldwide.

METHODS

We used individual-level longitudinal data from the Cape Area Panel Study (CAPS) from 2005 to 2009 on black African women (20-30 years old in 2009) to assess the association between perceived HIV-risk in 2005 and the probability of testing HIV-positive four years later. We then estimated multivariable logistic regressions using cross-sectional data from the 2009 CAPS wave to assess the relationship between risk perceptions and a wide range of demographic, sexual behaviour and psychosocial covariates of perceived HIV-risk.

RESULTS

We found that the proportion testing HIV-positive in 2009 was almost identical across perceived risk categories in 2005 (no, small, moderate, great) (χ ²  = 1.43, p = 0.85). Consistent with epidemiologic risk factors, the likelihood of reporting moderate or great HIV-risk perceptions was associated with condom-use (aOR: 0.57; 95% CI: 0.36, 0.89; p < 0.01); having ≥3 lifetime partners (aOR: 2.38, 95% CI: 1.53, 3.73; p < 0.01); knowledge of one's partner's HIV status (aOR: 0.67; 95% CI: 0.43, 1.07; p = 0.09); and being in an age-disparate partnerships (aOR: 1.73; 95% CI: 1.09, 2.76; p = 0.02). However, the likelihood of reporting moderate or great self-perceived risk did not vary with sexually transmitted disease history and respondent age, both strong predictors of HIV risk in the study setting. Risk perceptions were associated with stigmatising attitudes (aOR: 0.53; 95% CI: 0.26, 1.09; p = 0.09); prior HIV testing (aOR: 0.21; 95% CI: 0.13, 0.35; p < 0.01); and having heard that male circumcision is protective (aOR: 0.38; 95% CI: 0.22, 0.64; p < 0.01).

CONCLUSIONS

Results indicate that HIV-risk perceptions are inaccurate. Our findings suggest that this inaccuracy stems from HIV-risk perceptions being driven by an incomplete understanding of epidemiological risk and being influenced by a range of psycho-social factors not directly related to sexual behaviour. Consequently, new interventions are needed to align perceived and actual HIV risk.

Efficacy of Mobile Serious Games in Increasing HIV Risk Perception in Swaziland: A Randomized Control Trial (SGprev Trial) Research Protocol

Background

The human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) continue to be a major public health problem in Sub-Saharan Africa (SSA), particularly in Swaziland, which has the highest HIV prevalence in this region. A wide range of strategies and interventions have been used to promote behavior change, though almost all such interventions have involved mass media. Therefore, innovative behavior change strategies beyond mass media communication are urgently needed. Serious games have demonstrated effectiveness in advancing health in the developed world; however, no rigorous serious games interventions have been implemented in HIV prevention in SSA.

Objective

We plan to test whether a serious game intervention delivered on mobile phones to increase HIV risk perception, increase intention to reduce sexual partnerships, and increase intention to know own and partners HIV status will be more effective compared with current prevention efforts.

Methods

This is a two-arm randomized intervention trial. We will recruit 380 participants who meet the following eligibility criteria: 18-29 years of age, own a smartphone running an Android-based operating system, have the WhatsApp messaging app, live in Swaziland, and can adequately grant informed consent. Participants will be allocated into a smartphone interactive, educational story game, and a wait-list control group in a 1:1 allocation ratio. Subsequently, a self-administered Web-based questionnaire will be issued at baseline and after 4 weeks of exposure to the game. We hypothesize that the change in HIV risk perception between pre- and post-intervention assessment is greater in the intervention group compared with the change in the control group. Our primary hypothesis is based on the assumption that increased perceived risk of HIV provides cues to engage in protective behavior. Our primary outcome measure is HIV risk perceived mean change between pre- and post-intervention compared with the mean change in the wait-list control group at 4-weeks post-intervention. We will use standardized regression coefficients to calculate the effect of the intervention on our primary outcome with P values. We will conduct both intention to treat and as treated analysis.

Results

This study is funded by Hayao Nakayama Foundation for Science & Technology and Culture; Grant number H26-A2-41. The research and development approval has been obtained from Kyoto University Graduate School and Faculty of Medicine Ethics Committee, Japan, and Swaziland’s Ministry of Health Ethics and Scientific committee. Results are expected in February 2017.

Conclusions

This study will provide evidence on the efficiency of a mobile phone interactive game in increasing HIV risk perception in Swaziland. Our findings may also be generalizable to similar settings in SSA.

Persistent misconceptions about HIV transmission among males and females in Malawi

Background

The prevalence of HIV in Malawi is one of the highest in sub-Saharan Africa, and misconceptions about its mode of transmission are considered a major contributor to the continued spread of the virus.

Methods

Using the 2010 Malawi Demographic and Health Survey, the current study explored factors associated with misconceptions about HIV transmission among males and females.

Results

We found that higher levels of ABC prevention knowledge were associated with lower likelihood of endorsing misconceptions among females and males (OR = 0.85, p < 0.001; OR = 0.85, p < 0.001, respectively). Compared to those in the Northern region, both females and males in the Central (OR = 0.54, p < 0.001; OR = 0.53, p < 0.001, respectively) and Southern regions (OR = 0.49, p < 0.001; OR = 0.43, p < 0.001, respectively) were less likely to endorse misconceptions about HIV transmission. Moreover, marital status and ethnicity were significant predictors of HIV transmission misconceptions among females but not among males. Also, household wealth quintiles, education, religion, and urban–rural residence were significantly associated with endorsing misconceptions about HIV transmission.

Conclusion

Based on our findings, we recommend that education on HIV transmission in Malawi should integrate cultural and ethnic considerations of HIV/AIDS.
