Predictors of unprotected sexual intercourse among HIV-infected patients receiving antiretroviral drugs in the Niger Delta Region of Nigeria

This study aims to evaluate the predictor of unprotected sexual intercourse among HIV-infected adults receiving antiretroviral therapy (ART) in a tertiary facility in the Niger Delta Region of Nigeria. A cross sectional study was undertaken in a 200 bed tertiary hospital in Bayelsa state, south-south Nigeria. A standardized pre-tested interviewer administered questionnaire was used to collect demographic, clinical and sexual history from consecutive HIV-1 infected adults receiving ART for at least 6 months. Independent predictors of unprotected sexual intercourse (defined as irregular condom use or unprotected sex in previous 6months) were determined using an unconditional logistic regression model. Out of 241 patients studied, 71.8% were females, 48.5% were married, and 20.7% had a sexual partner that is HIV-1 infected. Sixty (24.9%) patients engaged in unprotected sex, 86 (35.7%) used condom consistently and 95 (39.4%) abstained. Female sex, being currently married, age18–35years, partner being HIV-positive and living with sexual partner were significant associated with risky sex. Female sex, age18–35years and being currently married were the only independent predictors of unprotected sex. HIV-infected adults receiving ART in resource limited settings are potential sources of secondary transmission of HIV. Condom use in the prevention of secondary transmission of HIV in study area should target females, young adults and married couples.     

Antiretroviral Treatment and Sexual Risk Behavior in South Africa

The sexual behavior of individuals living with HIV determines the onward transmission of HIV. With the understanding that antiretroviral therapy (ART) prevents transmission of HIV, the sexual behaviors of the individuals not on ART with unsuppressed viral loads becomes of the greatest importance in elucidating transmission. We assessed the association between being on ART and sexual risk behavior among those living with HIV in a nationally representative population-based cross-sectional survey of households in South Africa that was conducted in 2012. Of 2237 adults (aged 15–49) who tested HIV-seropositive, 667 (29.8 %) had detectable antiretroviral drugs in their blood specimens. Among males, 77.7 % of those on ART reported having had sex in the past year contrasted with 88.4 % of those not on ART (p = 0.001); among females, 72.2 % of those on ART reported having had sex in the past year while 80.3 % of those not on ART did (p < 0.001). For males and females, the odds of reporting consistent condom use and condom use at last sex were statistically significantly higher for individuals on ART compared to those not on ART (males: consistent condom use aOR 2.8, 95 % CI 1.6–4.9, condom use at last sex aOR 2.6, 95 % CI 1.5–4.6; females: consistent condom use aOR 2.3, 95 % CI 1.7–3.1, condom use at last sex aOR 2.3, 95 % CI 1.7–3.1), while there were no statistically significant differences in odds of reporting multiple sexual partners in the past year. In this nationally representative population-based survey of South African adults, we found evidence of less risky sexual risk behavior among people living with HIV on ART compared to those not on ART.     

Sexual behaviors during antiretroviral therapy among HIV-infected patients, Thailand

An increasing trend in sexual risk behavior has occurred in the era of antiretroviral therapy (ART) in Thailand. This study was conducted to identify sexual risk behavior and examine relationships between unprotected sex and CD4 levels among HIV-infected patients receiving ART in the National Antiretroviral Program. A cross-sectional survey was conducted in 460 HIV-infected patients age 18-49 years who visited the out-patient clinic of Bamrasnaradura Infectious Diseases Institute in February 2006 by using a standardized self-administered questionnaire. The results show that 60.4% of participants were men. The median most recent CD4 cell count during the prior 6 months was 261 cells/mm3. Twenty-three percent of the participants who had no sexual activity after they knew their HIV positive status started having sex again after receiving ART with a 12-week median duration period from starting ART to having first sex. There was a significant difference between the number of those having sexual activity before and after starting ART (p-value=0.013). Fifty-six percent of participants had sex during the previous 6 months. Of these, 26.5% had sex with commercial partners and 28.4% with non-regular partners. Inconsistent condom use, with commercial partners or non-regular partners, in females (35.3-36.8%) was higher than in males (7.8-11.1%). Participants with a known HIV-negative regular partner were 0.25 times more likely to have unprotected sex than those with a known HIV-positive regular partner (adjusted OR, 0.25; 95%CI, 0.09-0.73). No association between unprotected sex and CD4 levels was found. The findings support the need for reinforcing risk reduction programs among HIV-infected persons, particularly couple counseling, and promoting awareness of risk of acquirring sexually transmitted infections and drug-resistant strains of HIV.     

Sexual risk behaviors among heterosexual HIV serodiscordant couples in the era of post-exposure prevention and viral suppressive therapy

OBJECTIVES: To describe awareness and use of antiretroviral treatments, viral load monitoring, and post-exposure prevention; to assess changing concerns about HIV transmission; and to examine the effect of these advances on sexual behavior in HIV-serodiscordant heterosexual couples. METHODS: Cross-sectional analysis of a baseline sample of 104 couples (n = 208 individuals) from the California Partners Study II, an intervention trial for HIV-serodiscordant couples in California. Questions on sexual practices, viral load testing, HIV treatment, post-exposure prevention, and their effect on sexual behaviors, risk taking and transmission concerns were measured at intake. RESULTS: Over two-thirds of couple members surveyed reported unprotected sex with their partner in the past 6 months. Among seropositive respondents, 37% were taking protease inhibitor therapy, 92% had undergone viral load testing, and of those, 40% said it had ben undetectable at their most recent test. Most respondents, regardless of serostatus, said that viral load testing and awareness of post-exposure prevention had no effect on their condom use. In addition, perceiving that their partner had an undetectable viral load was associated with having protected sex among seronegative subjects (P < 0.05). Seropositive respondent taking protease inhibitors were 2.4 times less likely to report unprotected sex compared with those not taking protease inhibitors (P = 0.05). However, up to 33% of seropositive and 40% of seronegative respondents acknowledged decreased transmission concerns in the light of the new HIV treatments. In comparison with their seropositive partners, seronegative individuals were more likely to acknowledge increased risk taking and decreased HIV transmission concerns (P < 0.05). CONCLUSIONS: New medical advances were not associated with unprotected sex in HIV-serodiscordant couples. However, new treatment options may decrease concerns about HIV transmission, particularly among seronegative partners. Providers should discuss the effect of antiretroviral treatments on sexual transmission risk with their patients. The inclusion of seronegative partners in counseling interventions may decrease risk taking in serodiscordant couples.     

Safer sexual behaviors after 12 months of antiretroviral treatment in Mombasa, Kenya: a prospective cohort

Roll-out of antiretroviral treatment (ART) raises concerns about the potential for unprotected sex if sexual activity increases with well-being, resulting in continued HIV spread. Beliefs about reduced risk for HIV transmission with ART may also influence behavior. From September 2003 to November 2004, 234 adults enrolled in a trial assessing the efficacy of modified directly observed therapy in improving adherence to ART. Unsafe sexual behavior (unprotected sex with an HIV-negative or unknown status partner) before starting ART and 12 months thereafter was compared. Participants were a mean 37.2 years (standard deviation [SD] = 7.9 years) and 64% (149/234) were female. Nearly half (107/225) were sexually active in the 12 months prior to ART, the majority (96/107) reporting one sexual partner. Unsafe sex was reported by half of those sexually active in the 12 months before ART (54/107), while after 12 months ART, this reduced to 28% (30/107). Unsafe sex was associated with nondisclosure of HIV status to partner; recent HIV diagnosis; not being married or cohabiting; stigma; depression and body mass index <18.5 kg/m(2). ART beliefs, adherence, and viral suppression were not associated with unsafe sex. After adjusting for gender and stigma, unsafe sex was 0.59 times less likely after 12 months ART than before initiation (95% confidence interval [CI] = 0.37-0.94; p = 0.026). In conclusion, although risky sexual behaviors had decreased, a considerable portion do not practice safe sex. Beliefs about ART's effect on transmission, viral load, and adherence appear not to influence sexual behavior but require long-term surveillance. Positive prevention interventions for those receiving ART must reinforce safer sex practices and partner disclosure.     

The associations of voluntary counseling and testing acceptance and the perceived likelihood of being HIV-infected among men with multiple sex partners in a South African township

This paper examines the socio-demographic factors and sexual risk behaviors (condom use, number of sexual partners, STI symptoms) associated with voluntary counselling and testing (VCT) acceptance and self-perceived risk of being HIV-infected among black men with multiple and younger sex partners in a South African township outside of Cape Town. Using respondent driven sampling, we interviewed 421 men, of whom 409 (97.3%) consented to provide a dried blood spot, 12.3% were HIVinfected (95% confidence intervals [CI.] 8.3, 16.9) and 47.2% (CI. 41.1, 53.6) accepted on site VCT. Twenty six percent (CI. 20.2, 30.7) reported having an HIV test in the past year. Few men perceived themselves as very likely to be infected with HIV (15.6%; CI. 10.4, 20.5). VCT acceptance was significantly associated with being older, married or living with a partner, having higher education, having four to six partners in the past three months and testing HIV positive. Self-perceived likelihood of being HIV infected was significantly associated with low condom use and having seven or more partners in the past three months, and testing HIV positive. These findings indicate that men correctly understand that engaging in certain HIV risk behaviors increases the likelihood of HIV-infection. However, those who perceive themselves at high risk of having HIV do not seek testing. Further investigation into the psychological and cultural barriers to reducing risky sexual behaviors and accessing VCT and other HIV services is recommended.     

Sexual Risks Among Southern Thai Drug Injectors

Sexual risks for HIV transmission among injection drug users (IDUs) in Thailand are not well characterized. We surveyed 272 male IDUs about their background, sexual behaviors, and drug use at drug treatment clinics in southern Thailand. HIV seroprevalence was determined using enzyme immunoassay. Fifty-six percent of participants were sexually active, of whom 88% had sex mostly with a noninjecting regular partner (wife or steady girlfriend), reporting low rates (34%) of condom use. Among sexually active IDUs, 43% were HIV infected and only a few were aware of their HIV serostatus. Condom use was associated with history of HIV voluntary counseling and testing (VCT) and poor perceived health status in multivariate analysis. Unprotected sex with regular sexual partners is frequent among IDUs in southern Thailand, where most IDUs have not sought VCT services. AIDS prevention efforts should address access to VCT and condom promotion to sexually active couples to prevent sexual transmission of HIV.     

Fertility desires and preferences for safer conception strategies among people receiving care for HIV at a publicly-funded clinic in Seattle,WA

Understanding fertility desires and preferences for HIV prevention among individuals living with HIV, including the potential use of pre-exposure prophylaxis (PrEP) by HIV uninfected partners, can inform the delivery of safer conception counseling to reduce the risk of HIV transmission during pregnancy attempts. Men and women, predominantly heterosexual, engaged in HIV care in Seattle, WA, self-administered a questionnaire and we abstracted antiretroviral therapy (ART) status and HIV viral levels from medical records. We summarized participants’ sexual behavior, fertility desires, and preferences for safer conception strategies and used log-binomial regression to identify demographic, sexual, and behavioral factors associated with perceived acceptability of PrEP for HIV uninfected partners during pregnancy attempts. 52% of the 150 participants were female and the mean age was 48 years (range 23–74). 94.7% of participants were using ART and 79.3% had HIV viral load < 40 copies/mL. 22.2% of men and 34.6% of women reported that a healthcare provider had initiated discussion about fertility desires. 28.7% of participants were reproductive-age and desired children. Among sexually active reproductive-age participants with fertility desires, 56.3% reported inconsistent condom use and 62.5% did not report using effective birth control. 74.4% of reproductive age participants with fertility desires perceived that PrEP would be acceptable to an HIV uninfected partner and there were no significant predictors of PrEP acceptability. Nearly one third of reproductive-aged individuals living with HIV expressed fertility desires, highlighting a need for safer conception counseling in this setting. PrEP and ART were favored safer conception strategies.     

Living with discordance: knowledge, challenges, and prevention strategies of HIV-discordant couples in Uganda

Prevalence of HIV-discordance among couples in sub-Saharan Africa is high. Negative partners are at high risk of HIV infection but few HIV/AIDS service providers have developed effective counseling messages for HIV-discordant couples. To identify clients' explanations for discordance, challenges, and prevention strategies, 24 in-depth interviews and 4 focus group discussions were conducted with 32 female and 35 male members of HIV-discordant couples who sought HIV voluntary counseling and testing (VCT) in Uganda. In addition, counselor explanations for discordance were gathered from 62 counselor trainers during 3 interactive workshops. Misconceptions about discordance were widespread among clients and counselors. Common explanations included: the concept of a hidden infection not detectable by HIV tests, belief in immunity, the thought that gentle sex protected HIV-negative partners, and belief in protection by God. Such explanations for discordance reinforced denial of HIV risk for the negative partner within discordant couples and potentially increased transmission risk. Couples identified negotiation of sexual relations as their most formidable challenge. Prevention strategies included condom use, abstinence and separation of beds, contractual agreements for outside sexual partners, and relationship cessation. Discordant couples represent a critical risk group and improved counseling protocols that clearly explain discordance, emphasize high risk of transmission, and support risk reduction are urgently needed.     

Sexual Risk Behaviors Among HIV-Infected South African Men and Women with Their Partners in a Primary Care Program: Implications for Couples-Based Prevention

We studied 1163 sexually-active HIV-infected South African men and women in an urban primary care program to understand patterns of sexual behaviors and whether these behaviors differed by partner HIV status. Overall, 40% reported a HIV-positive partner and 60% a HIV-negative or status unknown partner; and 17.5% reported >2 sex acts in the last 2 weeks, 16.4% unprotected sex in the last 6 months, and 3.7% >1 sex partner in the last 6 months. Antiretroviral therapy (ART) was consistently associated with decreased sexual risk behaviors, as well as with reporting a HIV-negative or status unknown partner. The odds of sexual risk behaviors differed by sex; and were generally higher among participants reporting a HIV-positive partner, but continued among those with a HIV-negative or status unknown partner. These data support ART as a means of HIV prevention. Engaging in sexual risk behaviors primarily with HIV-positive partners was not widely practiced in this setting, emphasizing the need for couples-based prevention.     

Sexual behaviors of individuals with HIV living in South India: a qualitative study.

Formative data on the sexual behaviors of HIV-infected individuals in regions disproportionately affected by the epidemic can help generate hypotheses about sexual risk taking in HIV-infected individuals and shape interventions to prevent further transmission. India is home to the highest number of HIV-infected individuals in the world, and very little information is available about the sexual behaviors of HIV-infected Indians. The present qualitative study presents themes from individual in-depth interviews with 30 HIV-infected individuals in South India. The sample included individuals from demographic groups that may experience different risk factors (five individuals each: from men who have sex with men, sex workers, married men, married women, injection drug users, and truck drivers ormen who travel for work). Across the groups, the three most frequently discussed themes involved (a) sexual behavior change (sexual risk reduction after HIV diagnosis, sexual behavior remaining safe after initiation of ART treatment), (b) motivations to reduce risk (motivation to protect one's self against further infection, to protect others from infection), and (c) barriers to reduce risk (complexity and stigma associated with condom negotiation, perception of HIV-infected peers being less concerned about protecting others, condom use as linked to gender and sexual roles, condom use as inconvenient or unappealing). This qualitative data can be used to generate hypotheses about sexual risk taking in HIV-infected individuals in South India, to inform models of risky behaviors of HIV-infected individuals for quantitative studies, and to lay the groundwork for secondary prevention intervention efforts that enhance facilitators and reduce barriers of safer sex articulated by the interviewees.     

A qualitative study of sexual behavior change and risk compensation following adult male circumcision in urban Swaziland

Male circumcision has been shown to reduce the risk of heterosexual transmission of HIV infection in men by up to 60% in three randomized controlled trials. Less is known, however, about sexual behavior change in men who have been circumcised and whether male circumcision's protective effect leads to riskier sexual behaviors. This study used qualitative in-depth interviews to understand men's sexual behavior after circumcision and to determine whether and how men participated in riskier sexual behaviors following male circumcision. Men in urban Swaziland, circumcised in the previous 12 months, were recruited and asked about their perceptions of sexual risk and sexual behavior post-circumcision. Results showed that following circumcision, men experience changes in both their sexual attitudes and behavior, which can be considered both protective and risky for HIV transmission. Most of them described protective changes (e.g., more responsible attitudes towards safe sex, reducing sexual temptation and partners, easier condom use). A minority, however, experienced increased sexual risk-taking, typically during a brief period of sexual experimentation shortly after circumcision. HIV counseling and counseling throughout the circumcision process is shown to be critical in influencing protective behaviors. Findings in this study confirm the existence of risk compensation following circumcision; however, this study adds important contextual insight about precisely when and why such risk-taking occurs. Nevertheless this study suggests that male circumcision scale-up as an HIV prevention strategy is likely to foster protective behavior change among men. The integration of HIV counseling with circumcision provision remains critical for effectively mitigating HIV risk behavior as male circumcision gains momentum as a viable HIV prevention tool.     

Acquisition of new sexual partners among women with HIV infection: patterns of disclosure and sexual behavior within new partnerships.

This study describes the sexual behavior of HIV-positive women within new versus more established relationships and determines whether beliefs about HIV antiretroviral therapy (ART) impact these behaviors. The Women's Interagency HIV Study is a longitudinal cohort study of HIV among women in the United States. Sexually active HIV-positive women (N = 1,090) completed interviews on beliefs and behaviors at 6-month intervals. Data were analyzed for the period between April 2002 and March 2003. Of 1,517 sexual partners reported, 32% were newly acquired within the previous 6 months. As compared with more established sexual relationships, newer partnerships were characterized by greater condom use consistency (odds ratio = 1.8, 95% confidence interval = 1.4 -2.3). Holding beliefs that ART is protective for HIV transmission impacted the relationship between partner type and condom use. In established relationships, 63% reported consistent condom use if they believed that ART is not protective, whereas 54% reported consistent condom use if they believed that ART is protective. Conclusions: These findings highlight the importance of ongoing support for sexual risk reduction among women with HIV-infection and for strategies that reduce the strength of relationships between ART beliefs and sexual risk behavior.     

Sexual behaviors and sexual risk in a prospective cohort of HIV-positive men and women in New York City, 1994-2002: implications for prevention.

As an ever-increasing number of people infected with HIV are living longer, healthier lives, concerns about continued transmission are growing along with an awareness of the need to develop "prevention for positives." This study of HIV-positive adults in New York City is the first examination of patterns of sexual behavior in a large, representative cohort of HIV-infected individuals followed over an extended time period. A total of 968 HIV-positive adults were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many persons were not sexually active at all for months at a time; some continued to have multiple partners. Over one third of the cohort had one or more periods when they had engaged in unprotected sex with a partner who was HIV-negative or status unknown (unsafe sex) and one in five reported exchanging sex. Periods of unsafe sex alternated with periods of safer sex. Predictors of sexual risk varied by gender, and among men who had sex with men, and men sexually active with women only. Contextual factors such as partner relations, housing status, and receipt of HIV services were as important as individual attributes as predictors of unsafe sex and sex exchange. The variability observed in sexual risk behavior reported over time provides new insight into the importance of engaging persons living with HIV in ongoing prevention programs.     

Engagement in HIV care and sexual transmission risk behavior among men who have sex with men using online social/sexual networking in Latin America

HIV/AIDS in Latin America is concentrated among men who have sex with men (MSM). However, accurate estimates of engagement in HIV care in this population can be difficult to ascertain because many do not self-identify as MSM. Given evidence of decreased HIV transmissibility in the context of antiretroviral therapy (ART) adherence, identifying individuals not in care who are engaging in HIV transmission risk behavior is crucial for secondary prevention. Primary aims of this study were to examine engagement in care from testing to ART adherence among MSM using online social/sexual networking across Latin America, and whether individuals not in care at each step reported greater sexual transmission risk behavior than those in care. In the overall sample (n = 28,779), approximately 75% reported ever being tested for HIV, and 9% reported having received an HIV diagnosis. Among known HIV-infected individuals, 20% reported not being in care, 30% reported not taking ART, and 55% reported less than 100% ART adherence. Over one-third of HIV-infected individuals reported sexual HIV transmission risk behavior, defined as unprotected anal intercourse (UAI) with a male partner of different/unknown HIV serostatus in the past three months. HIV-infected individuals not engaged in care more often reported UAI compared to those in care (OR = 1.29; 95% CI = 1.01–1.66). Although not statistically significant, HIV-infected individuals not on ART more often reported UAI compared to those on ART (OR = 1.18; 95% CI = 0.94–1.47). Individuals who reported less than 100% ART adherence more often reported UAI compared to individuals with 100% adherence (OR = 1.55; 95% CI = 1.26–1.90). Findings demonstrate that a substantial portion of HIV-infected MSM in Latin America who are likely not virologically suppressed from lack of ART use or adherence report sexual HIV transmission risk. Tailoring secondary HIV prevention for MSM in Latin America who are not in HIV care or adherent to ART may be warranted.     

Antiretroviral resistance and high-risk transmission behavior among HIV-positive patients in clinical care

BACKGROUND: HIV-positive patients receiving antiretroviral therapy (ART) who engage in HIV transmission behaviors may harbor and transmit drug-resistant HIV. However, little is known about the risk behaviors of these patients, potential partners exposed and the relationship of these to ART resistance. OBJECTIVE: To determine the relationship of HIV drug resistance and continuing HIV transmission risk behavior among HIV-positive patients in care. METHODS: A retrospective, cross-sectional study of HIV transmission risk behavior and HIV drug resistance data from 333 HIV-positive patients. RESULTS: Among a diverse population of 333 HIV-positive patients, 75 (23%) had unprotected sex during the previous 3-months, resulting in 1126 unprotected sexual events with 191 partners of whom 155 were believed by patients to be HIV-negative or of unknown status. Eighteen of the 75 (24%) had resistant HIV and 207 unprotected sexual events, exposing 18% of the HIV- or status unknown partners. There was no difference in the proportion of patients engaging in unprotected sex who had undetectable viral load (VL) (22%): VL > 400 copies/ml without resistance (20%) and VL > 400 copies/ml with resistance (26%). Resistance and risk behavior was predicted only by lower mental health scores (odds ratio, 10.3; 95% confidence interval, 1.7-18.6). CONCLUSION: A substantial minority (23%) of patients in clinical care engaged in HIV sexual transmission risk behavior. A small subset of these also had ART-resistant HIV. However, this core group (approximately 5% of all patients) accounted for a large number of high-risk HIV transmission events with resistant virus, exposing a substantial number of partners.     

Disclosure of HIV Status to Sex Partners Among HIV-Infected Men and Women in Cape Town, South Africa

This study examines factors influencing HIV sero-status disclosure to sex partners among a sample of 630 HIV-infected men and women with recent sexual contact attending anti-retroviral therapy (ART) clinics in Cape Town, South Africa, with a focus on sex partner type, HIV-related stigma, and ART as potential correlates. About 20% of the sample had not disclosed their HIV status to their most recent sex partners. HIV disclosure to sex partner was more likely among participants who had a steady sex partner [Adjusted odds ratio (AOR) = 2.7; 95% CI: 1.6–4.6], had a partner with known-HIV status [AOR = 7.8; 95% CI: 3.2–18.7]; perceived less stigma [AOR = 1.9; 95% CI: 1.2–2.9]; and were on ART [AOR = 1.6; 95% CI: 1.1–2.3]. Stratified analyses by the type of sex partner further reveals that stigma and ART were significantly associated with HIV disclosure within steady relationships but were not significant correlates of HIV disclosure with casual sex partners. The findings support a positive prevention strategy that emphasizes increased access to ART, and behavioral interventions to reduce casual sex partnerships for persons who are HIV-positive. Mitigating the influence of HIV stigma on HIV status disclosure particularly within steady sex partnerships is also important and may be accomplished through individual and couple counseling.     

Childhood victimization and HIV risk behaviors among university students in Saint-Petersburg,Russia

Exposure to childhood victimization and abuse has been shown to affect HIV risk in adult populations. In Russia, the existence of child abuse was largely unrecognized until 1990s and its behavioral consequences remain understudied. Our goal was to assess childhood victimization and HIV risk behavior among young adults in Saint-Petersburg, Russia: 743 students from 15 local universities were surveyed. Unprotected sexual intercourse was the most common type of HIV risk behavior: study participants reported no condom use at last intercourse (65.17%), inconsistent condom use (58.43%) and 30.81% never used condoms in the past 3 months. Childhood sexual victimization was significantly associated with unprotected sex at last intercourse and with inconsistent condom use in the past 3 months. Young adults in Russia are vulnerable to HIV epidemic due to the pervasiveness of unprotected sexual intercourse, and childhood sexual victimization is associated with risky sexual behavior in this population. Efforts to combat HIV epidemic in Russia must include programming for the prevention of childhood sexual abuse and the development of services for the survivors of childhood victimization.     

Sexual behavior and HIV risk across the life course in rural South Africa: trends and comparisons

There is limited information about sexual behavior among older Africans, which is problematic given high HIV rates among older adults. We use a population-based survey among people aged 15–80+ to examine the prevalence of sexual risk and protective behaviors in the context of a severe HIV epidemic. We focus on variation across the life course, gender and HIV serostatus to compare the similarities and differences of young, middle aged, and older adults. Younger adults continue to be at risk of HIV, with potential partners being more likely to have been diagnosed with an STI and more likely to have HIV, partner change is high, and condom use is low. Middle aged and older adults engage in sexual behavior that makes them vulnerable at older ages, including extramarital sex, low condom use, and cross-generational sex with people in age groups with the highest rates of HIV. We find insignificant differences between HIV positive and negative adults’ reports of recent sexual activity. This study provides new information on sexual behavior and HIV risk across the life course in rural South Africa to inform HIV prevention and treatment programing.
