Sexual risk behaviors and HIV risk among Americans aged 50 years or older: a review

"Are they going to recollect who they need to contact?": understanding sexually transmitted infection transmission risks among older Canadians who winter in the United States

BACKGROUND

Sexually transmitted infections are on the rise in older populations globally, including among older travellers. International retirement migrants are older people who have retired from the workforce and travel abroad seasonally, typically during the winter months in their home countries. The transnational nature of this practice may challenge public health efforts to control the spread of sexually transmitted infection and encourage treatment. This study focuses on Yuma, Arizona, a popular destination for Canadian international retirement migrants who winter in the United States, to examine the sexual health risks associated with their seasonal travel.

METHODS

Utilizing a qualitative case study approach, this research involved semi-structured interviews conducted remotely with key informants in Yuma (n = 10) who held various health care and administrative roles. Participants provided insights into sexual health risks based on their extensive interactions with Canadian seasonal migrants and their knowledge of the social dynamics within retirement communities. Interviews were transcribed verbatim, coded using NVivo software, and thematically analyzed to identify risk factors for sexually transmitted infections among Canadian international retirement migrants wintering in Yuma.

RESULTS

Findings revealed three main risks that may contribute to exposure to sexually transmitted infections and potential transmission: social dynamics within tight-knit retirement migrant communities that facilitate unsafe sexual practices (i.e., risky practices); barriers to accessing diagnostic services, such as costs and lack of established local care (i.e., risky care access); and challenges in following standard treatment and public health protocols due to logistical difficulties in ensuring follow-up (i.e., risky treatment decisions). Key informants noted that lifestyle choices, including the use of alcohol and drugs, can exacerbate these risks. Health care access barriers driven by travel health insurance and mobility limitations further complicate the diagnosis and treatment of sexually transmitted infections for Canadian international retirement migrants while abroad.

CONCLUSIONS

This study highlights the complex interplay of social behaviours and health care barriers that heighten the risk of sexually transmitted infection transmission among Canadian retirement migrants in the transnational context of Yuma. Extended diagnostic and treatment services, comprehensive sexual health education in pre- and post-travel consultations, as well as inclusive travel health insurance coverage could significantly improve the sexual health outcomes for this population.

PrEP-eligible behaviours and condom use among sexually active older adults in China: Findings from the sexual well-being (SWELL) study

OBJECTIVES

Older adults remain sexually active and at risk of sexually transmitted infections (STIs). This study aimed to explore consistent condom use and pre-exposure prophylaxis (PrEP)-eligible behaviours and their correlates among sexually active older adults in China.

STUDY DESIGN

Cross-sectional study.

METHODS

Data were collected from a multicentre cross-sectional survey in China between June 2020 and December 2022. Eligibility criteria were community-dwelling older adults aged ≥50 years who were sexually active (i.e. had oral, vaginal or anal sex in the past year). In-person questionnaire interviews included demographic characteristics, general health and sexual health information.

RESULTS

In total, 1332 sexually active older adults were recruited in the study. Overall, 33.7 % (449/1332) of participants consistently used a condom in the past year and 7.9 % (105/1332) reported PrEP-eligible behaviours. Consistent condom use was significantly associated with the following characteristics: age (only for women aged 50-59 years [adjusted odds ratio (aOR) 0.60, 95 % confidence interval (CI): 0.36-0.98]; women aged 60-69 years [aOR 0.27, 95 % CI: 0.10-0.71]), living alone (men [aOR 0.40, 95 % CI: 0.20-0.79]; women [aOR 0.27, 95 % CI: 0.10-0.72]), body mass index (men [aOR 1.59, 95 % CI: 1.18-2.14]; women [aOR 1.76, 95 % CI: 1.13-2.73]), general health status (men reporting 'fair' health [aOR 0.62, 95 % CI: 0.39-0.97]; women reporting 'very good' health [aOR 0.39, 95 % CI: 0.16-0.96]), talking about sex (men [aOR 1.67, 95 % CI: 1.23-2.26]) and knowledge of condom use to prevent sexually transmitted infections (men [aOR 1.52, 95 % CI: 1.06-2.18]). PrEP-eligible behaviours were more likely in men (aOR 1.76, 95 % CI: 1.08-2.90) and in individuals who were not in a stable relationship (aOR 4.80, 95 % CI: 2.41-9.54) and who lived alone (aOR 2.02, 95 % CI: 1.07-3.82).

CONCLUSION

Consistent condom use was moderate among sexually active older adults in China. More than one-quarter of older adults who lived alone reported PrEP-eligible behaviours. Comprehensive intervention measures should consider the characteristics and health needs of community-dwelling older adults.

Increased trends in reported sexually transmitted infections according to age groups and sex in Spain, 2016-2022

OBJECTIVE

Our objective was to assess trends in three sexually transmitted infections (STIs) - gonorrhoea, chlamydia and syphilis - in Spain, by age group and sex from 2016 to 2022.

STUDY DESIGN

Retrospective observational study.

METHODS

Data from epidemiological surveillance system were used to calculate the incidence rate for each STIs by age group and sex. Poisson regression was employed to examine the trends for 2016 to 2022.

RESULTS

For gonorrhoea, higher incidence rates were observed among men than women for all period. The incidence rate ratio (IRR) varied between 1.14 (95% CI 1.12-1.16) for the 15-19 age group to 1.24 (1.23-1.25) for the 35-44 age group among men, and between 1.14 (1.09-1.19) for 55 years or more to 1.27 (1.24-1.29) for the 15-19 age group among women. For chlamydia, women showed higher incidence rate for all age groups than men during the period. Individuals aged 55 years and over showed the highest increase, IRR = 1.30 (1.27-1.34) for men, while it was the lowest for women, IRR = 1.22 (1.16-1.27). The incidence rates for syphilis were lower than for the other STIs. IRR values varied between 1.04 (1.02-1.06) in the 20-24 age group and 1.15 (1.14-1.16) in the 35-44 age group for males; and between 1.13 (1.06-1.16) for the 25-34 age group and 1.18 (1.13-1.25) for the 25-34 age group for females.

CONCLUSION

STIs are more frequent in people aged 25-34 and are increasing in all age groups. However, the rise is most pronounced among older men and among younger women.

A scoping review: Forced/coerced sterilization as a socio-cultural risk factor for sexually transmitted HIV for older Black women

Understanding socio-cultural factors that influence older (age 50 and up) Black women's risk for sexually transmitted HIV has often been absent from policies and programs. This scoping review asked: What does academic literature reveal about forced/coerced sterilization as a risk factor for older Black women who are disproportionately affected by sexually transmitted HIV? Using the Arksey and O'Malley scoping review methodology, the authors identified academic and gray literature published between 2000 and 2023. Of the 407 sources identified and screened, three articles met the criteria for inclusion. One study focused on birth control conspiracy beliefs, another focused on racial differences in Norplant use, and the third focused on the intergenerational transmission of mistrust of medical care that influences HIV prevention among Black Americans. The study findings suggest that because the link has not been made between socio-cultural factors that impact older Black women's reproductive health practices, further investigation is warranted.

Adaptation and validation of a condom-related stigma scale for older adults in China

BACKGROUND

Condom use has long been recommended as an effective method for preventing HIV/AIDS. However, a large proportion of older adults in China reported not using condoms, leading to an alarming increase in HIV prevalence among this population. Negative attitudes, especially condom-related stigma, have been identified as the main barrier. However, no condom-related stigma scale has been developed or validated for older adults in the Chinese cultural context. This study aimed to adapt and validate a condom-related stigma scale for older adults (CRSS-OA) in China, based on a scale previously developed for men who have sex with men (CRSS).

METHODS

Based on qualitative interviews, we adapted and revised the CRSS to better address the ageism and unique stigma faced by older adults in the Chinese cultural context. The reliability and validity of the adapted CRSS-OA were examined using a random sample of 498 older adults in Hunan Province, south-central China. Reliability was assessed by calculating Cronbach's alpha. Construct validity was assessed through exploratory and confirmatory factor analyses. Concurrent validity was assessed by examining the correlation between each factor of the CRSS-OA and two criterion scales (the HIV/AIDS Stigma Scale and the Aging Sexual Attitudes Scale). Predictive validity was evaluated by analyzing the association between condom-related stigma and engagement in condomless sexual behavior.

RESULTS

The adapted scale included 16 items, loading on three factors, and collectively explaining 70.646% of the variance. These factors were named "labeling condom use," "shaming condom purchase," and "violating traditional sex beliefs," demonstrating strong internal consistency with Cronbach's alpha coefficients of 0.942, 0.850, and 0.852, respectively. Concurrent validity was established by evaluating the correlation between each factor of the CRSS-OA and two criterion scales, with Pearson correlation coefficients ranging from 0.227 to 0.508 (p < 0.05). Predictive validity was assessed by measuring the scale's ability to correctly predict condomless sexual behavior, with an average predictability of 0.77.

CONCLUSIONS

The adapted CRSS-OA has proven to be a valid and cultural-adaptive tool for assessing condom-related stigma among older adults in China. Further studies are needed to explore the external validity of this scale in the future.

HIV Knowledge, Risk Factors, and Utilization of Services in the US Rural Deep South

BACKGROUND

HIV prevalence in the rural South remains high among Black Americans due to limited access to prevention and treatment services and poverty. HIV care inequities for Black Americans living in the rural South are further intensified by high mortality rates, low HIV health literacy, stigma, and discrimination. Few studies have focused on HIV knowledge and risk factors within Black Americans in the rural South.

METHODS

This cross-sectional study examined the association between HIV risk factors, HIV knowledge, and utilization of HIV and/or sexually transmitted infection (STI) testing services among Black Americans (N = 200) living in the rural South. HIV knowledge, risk factors, and utilization of testing services were assessed via The HIV Knowledge Questionnaire, The HIV Risk Factor Questionnaire, and three investigator-generated questions, respectively. Linear regression was used to examine the relationship between demographic characteristics, HIV knowledge, utilization of testing services, and HIV risk factors.

RESULTS

Among 200 participants, a smaller percentage (37.7%, n = 75) reported using HIV/STI testing services compared to non-users. Controlling for demographic covariates in the model, HIV knowledge (p < .0001) and marital status (p = .010) were significantly associated with HIV risk factors. HIV risk factors decreased as HIV knowledge increased. Individuals who reported being single also reported having fewer risk factors.

CONCLUSION

Future research should examine the impact of HIV education tailored for individuals with greater HIV risk factors within rural Black Americans. Studies exploring barriers to the utilization of HIV/STI testing services within Black American rural communities are warranted.

Increases in the susceptibility of human endometrial CD4+ T cells to HIV-1 infection post-menopause are not dependent on greater viral receptor expression frequency

Epidemiological evidence suggests that post-menopausal women are more susceptible to HIV infection following sexual intercourse than are younger cohorts for reasons that remain unclear. Here, we evaluated how menopause-associated changes in CD4+ T cell numbers and subsets as well as HIV coreceptor expression, particularly CCR5, in the endometrium (EM), endocervix (CX), and ectocervix (ECX) may alter HIV infection susceptibility. Using a tissue-specific mixed cell infection model, we demonstrate that while no changes in CD14+ macrophage infection susceptibility were observed, CD4+ T cell HIV-1 infection frequency increases following menopause in the EM, but not CX nor ECX. Unexpectedly, the CD4+ T cell expression of two known correlates of HIV infection susceptibly, CCR5 and integrin-α4β7, increased following menopause across all three tissues despite only being associated with increased infection frequency in EM derived CD4+ T cells. After controlling for changes in the expression of either receptor, both CCR5 and α4β7 expressing CD4+ T cells isolated from the EM of post-menopausal women remained more susceptible to HIV-1 infection than those isolated from pre-menopausal women. Shifts in T helper subset composition, including increases in Th1 frequency and decreases in Th17 and Treg frequency were also observed in the EM only following menopause, but did not correlate with increased infection frequency. Treatment of EM derived CD4+ T cells with 17β-estradiol (E2) prior to viral infection, reduced infection frequency independent of changes in either CCR5 or α4β7 expression frequency. Our results demonstrate that the susceptibility of EM derived CD4+ T cells to HIV-1 infection increases post menopause but is unlikely to be driven by increased expression frequency of either CCR5 or integrin-α4β7. These findings contribute to our understanding of how advanced age alters HIV infection risk which will become increasingly important as the human population continues to age.

Sexual behaviour and condom use of older adults living with HIV/AIDS in a treatment centre at Osogbo, south-west Nigeria

Objective

This study assessed the condom use and sexual behaviour of older adults living with HIV/AIDS at Osogbo, Osun State, Nigeria.

Methods

A descriptive cross-sectional study involving all adults receiving care at an HIV treatment centre that completed an interviewer administered questionnaire on their sexual behaviour and condom use. Data were analyzed using descriptive and inferential statistics.

Results

A total of 186 older adults completed the study. Their mean age (SD) was 54.5 (5.6) years. There are 114 (61.3%) females and 72 (38.7%) males. Two fifth 87 (46.8%) were sexually active with over half using condom (45, 51.7%) at last sexual intercourse. The determinants of condom use at last sexual intercourse included age 50-59 years (OR=3.34, 95% CI=1.21-9.25, p=0.020), lower education (OR=3.00, 95%CI=1.04-8.69, p=0.043), being married or have a partner (OR=3.25, 95%CI=1.11-9.52, p=0.031), partner's awareness of respondents' HIV status (OR=13.00, 95%CI=4.25-39.80, p<0.0001) and stigma experience from partner (OR=11.70, 95%CI=4.03-33.99, p=0.0001).

Conclusion

Older adults engage in high-risk sexual behaviour. It is necessary to encourage safer sex practices, stigma reduction and couple HIV counseling and testing.

Latent Class Analysis of Sexual Partnerships and Substance Use Across Generations

Sexually transmitted infections (STIs) remain an important public health concern for people of all age groups, with older age groups experiencing a notable increase in STI burden. Historically, most research into STI risk behaviors has focused on adolescents and young adults, leaving a paucity of research on the ways STI risk factors change over the life course. Additionally, age and cohort trends in STI risk factors can be challenging to investigate with standard statistical tools as they can be collinear and are subject to sociocultural and generational influences. To help address these issues, we used multi-group latent class analysis to identify and compare risk behavior profiles defined by responses to three sexual activity and three substance use variables, across and within four age groups. We identified six behavior profiles in the unstratified dataset and five behavior profiles in each of the four age stratified groups. The five behavior profiles identified in each of the age categories appear to reflect a similar set of five underlying profile "archetypes," with the exact composition of each age category's five profiles varying in the magnitude that specific behaviors are endorsed. Interestingly, despite the similarity of profiles across the four age groups, analyses indicate that the experience of belonging to any one of these five archetypes differs by age group. This variance is likely due group specific age, period, and cohort effects, and may indicate that, when estimating one's STI risk, it is better to compare them to their peers than to the population as a whole.

"I suppose in our culture, old means no sex": PLWH and healthcare provider views on factors influencing late HIV testing and diagnosis among older adults in Malaysia

The proportion of new HIV diagnoses among older adults aged ≥50 years continues to rise. Older adults are at higher risk of late diagnosis which is associated with higher treatment complexity and poorer health outcomes. Few studies in the Asia-Pacific region have explored factors contributing to late presentation and diagnosis in this population. Thus, our study aimed to explore factors influencing late HIV diagnosis among older adults ≥50 years in Malaysia. We conducted in-depth interviews with 16 older adults newly diagnosed with HIV (OPLWH) and focus group discussions with seven healthcare providers (HCPs) from different specialties in an academic tertiary hospital in Malaysia. All sessions were audio-recorded, transcribed verbatim and analysed thematically. Three main themes related to late diagnosis among OPLWH emerged: (1) challenge in recognizing HIV symptoms among older persons, (2) older persons and HCPs having low index of suspicion of HIV and (3) poor acceptance of HIV testing among older persons due to perceived personal and social identities. HCPs often missed HIV symptoms and these collectively culminated in OPLWH experiencing complex diagnostic journeys resulting in late HIV diagnosis. To reduce delays in HIV diagnosis, strategies are needed to improve HIV knowledge and risk perception among both older adults and HCPs.

The Association Between HIV-Related Stigma and the Uptake of HIV Testing and ART Among Older Adults in Rural South Africa: Findings from the HAALSI Cohort Study

HIV testing and antiretroviral therapy (ART) remain critical for curbing the spread of HIV/AIDS, but stigma can impede access to these services. Using data from the Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI), we used a multivariable logistic regression to examine the correlation between HIV-related stigma, HIV testing and ART uptake in older adults. We used four questions to measure stigma, with three assessing social stigma (reflecting social distancing preferences) and one assessing anticipated stigma (disclosure concern). We combined the three social stigma questions to generate a social stigma score ranging from 0 to 3, with higher scores indicating higher stigma. Anticipated stigma was prevalent 85% (95% CI 0.84-0.86), and social stigma was also frequent 25% (95% CI 0.24-0.27). Higher social stigma scores correlated with decreased HIV testing for all participants with social stigma. Compared to those with a score of 0, odds of testing decreased with higher stigma scores (OR = 0.66, 95% CI 0.53-0.81, p = 0.000) for a score of 1 and (OR = 0.56, 95% CI 0.38-0.83, p = 0.004) for a score of 3. ART uptake also decreased with higher social stigma scores among people living with HIV (PLWH), although it was significant for those with a score of 2 (OR = 0.41, 95% CI 0.19-0.87, p = 0.020). These findings emphasize that HIV-related stigma hampers testing and ART uptake among older adults in rural South Africa. Addressing stigma is crucial for improving testing rates, early diagnosis, and treatment initiation among the older population and achieving UNAIDS 95-95-95 targets.

Virologic failure and all-cause mortality among older people living with HIV/AIDS in South China

This retrospective cohort study investigated older people living with HIV/AIDS (PLWHA) characteristics, HIV care, and treatment outcomes among all cases between 1996 and 2019 in Guangxi, China. Secondary data were extracted from two national surveillance databases. Older (≥50 years old) and younger (18-49 years old) PLWHA were compared regarding demographic and behavioral characteristics, HIV care, virologic failure, and all-cause mortality. Older PLWHA accounted for 41.6% of all HIV cases (N = 144,952) between 1996 and 2019. The proportion of older cases increased from 10.4% to 64.8% for men and from 2.4% to 66.7% for women between 2002 and 2019. Heterosexual contact accounted for 96.0% of older adults. Moreover, older PLWHA had a lower median CD4 count at the HIV diagnosis (193 vs. 212 cells/μL, p < 0.0001) and were less likely to receive antiretroviral therapy (ART) than younger adults (72.1% vs. 86.1%, p < 0.001). The all-cause mortality risk of older PLWHA was 2.87 times of younger adults [adjusted hazard ratio (AHR) 2.87; 95% confidence interval (CI) 2.76-2.98]. In addition, older PLWHA reported an 18% increase in odds for virologic failure than younger adults (AOR 1.18; 95% CI 1.08-1.30). Therefore, enhanced HIV prevention and care are urgently needed in older people.

Individual, Social, and Structural Vulnerability for Black Women in the South: Implications for PrEP

Pre-exposure prophylaxis (PrEP) is an effective biomedical HIV prevention option, yet adoption among Black women, who are disproportionately impacted by HIV, is low. A nuanced understanding of the multi-level factors that contribute to elevated risk is necessary to better contextualize PrEP uptake. Qualitative data from Black women residing in the Southern U.S. who self-screened as HIV-negative, were collected via four focus groups (N = 27) to understand influences on HIV vulnerability and the potential role of PrEP in mitigating risk. Content analysis of transcribed data yielded multiple themes addressing: the pervasiveness of sexual partner sharing; lack of transparency regarding HIV status, disclosure, and testing; and social/cultural influences on HIV risk. Experiences with the health care system and providers were of particular concern. Findings demonstrate support for PrEP in this population and contribute to our understanding of individual, social, and structural factors to better inform PrEP promotion.

Sexual Satisfaction of Midlife Women Living With HIV in Canada: A Prospective Cohort Analysis

BACKGROUND

Although sexual activity and function decline in older women living with HIV, positive dimensions of sexual health, such as satisfaction, are relatively unexplored. We evaluated the prevalence of sexual satisfaction for midlife women with HIV and assessed its relation to women's physical, mental, and sociostructural experiences.

SETTING

We studied women in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) over 3 survey waves (2013-2018).

METHODS

We included women living with HIV aged ≥45 years who reported ever having consensual sex. Sexual satisfaction was assessed using an item from the Sexual Satisfaction Scale for Women and was dichotomized into satisfactory ("completely/very/reasonably satisfactory") and not satisfactory ("not very/not at all satisfactory"). Probable depression was based on CES-D ≥10. Multivariable logistic regression and fixed effects models determined correlates of sexual satisfaction. Reasons for sexual inactivity and alternate forms of sexual expression were also explored.

RESULTS

Among 508 midlife women, 61% were satisfied with their sexual lives at baseline. Women with probable depression had lower odds of sexual satisfaction than those without (aOR: 0.44; 95% CI: 0.27 to 0.71) and worsening depressive symptoms over time were associated with poorer sexual satisfaction ( P = 0.001). Increased sexual activity was associated with higher sexual satisfaction (aOR: 2.75; 95% CI: 1.54 to 4.91); however, 51% of women reporting sexual satisfaction were sexually inactive. Sexually inactive women engaged in alternate forms of sexual expression such as self-pleasure (37%) and intimate relationships without sex (13%).

CONCLUSION

Midlife women with HIV have high rates of sexual satisfaction, even in the absence of sexual activity. Depressive symptoms were closely associated with sexual dissatisfaction, alerting providers to the importance of screening for depression and sexual health together.

Pattern of contributing behaviors and their determinants among people living with HIV in Iran: A 30-year nationwide study

Introduction

A major shift in the routes of HIV transmission seams to be taking place in Iran. Our study aimed to investigate the 30-year trend of major HIV related behaviors in Iran.

Methods

The national HIV/AIDS registry database (from September 1986 to July 2016 with data on 32,168 people newly diagnosed with HIV) was used to study the 30 years trend and demographic determinants of major HIV related behaviors.

Results

The highest rate of drug injection (DI) among people living with HIV (PLHIV) was reported during 1996 to 1999 (p-for trend < 0.001) while the highest rate of sexual activity by minorities or hard to reach groups was during 2004 to 2011 (p-for trend < 0.001). Among males, drug injection was directly associated with being single (OR_{single/married} = 1.34), being unemployed (OR_{unemployed/employed} = 1.94) and having lower level of education (OR_{<highschool/≥highschool} = 2.21). Regarding females, drug injection was associated with being housewife (OR_{housewife/employed} = 1.35) and lower level of education (OR_{<highschool/≥highschool} = 1.85). In females, condomless sexual contact was more common among those younger (OR_20-29/<20 = 6.15), and married (OR_{married/single} = 7.76). However, among males those being single (OR_{married/single} = 0.82), being more educated (OR_{≥highschool/<highschool} = 1.24), and being unemployed (OR_{unemployed/employed} = 1.53) reported more sexual activity by minoritised or hard to reach groups.

Discussion

The pattern of major HIV related behaviors among Iranian males and females have been rapidly changing and people living with HIV (PLHIV) are being diagnosed at a younger age. Health education to younger individuals is an essential HIV controlling strategy among Iranian population. Implementation of surveys in hidden and hard-to-reach populations is also recommended.

Sexual Repertoire, Duration of Partnered Sex, Sexual Pleasure, and Orgasm: Findings from a US Nationally Representative Survey of Adults

In a confidential U.S. nationally representative survey of 2,525 adults (1300 women, 1225 men), we examined participants' event-level sexual behaviors, predictors of pleasure and orgasm, and perceived actual and ideal duration of sex, by gender and age. Event-level kissing, cuddling, vaginal intercourse, and oral sex were prevalent. Sexual choking was more prevalent among adults under 40. While women and men reported a similar actual duration of sex, men reported a longer ideal duration. Participants with same-sex partners reported a longer ideal duration than those with other-sex partners. Finally, findings show that gendered sexual inequities related to pleasure and orgasm persist.

An analysis of the relationship between HIV risk self-perception with sexual behaviour and HIV status in South African older adults

Objective: To examine how older adults perceive their own risk of acquiring HIV; and how this perception correlates with their sexual behaviour and HIV status.Methods: We used cross-sectional survey data for 435 adults aged 50 years and older from South Africa. All participants completed a questionnaire on their basic socio-demographic and economic factors, self-reported health, sexual behaviour, HIV knowledge and attitudes, and self-perceived risk of HIV acquisition. In addition, anthropometrical measurements (weight, height, blood pressure, cholesterol) and HIV testing were conducted. Multinomial logistic regressions were used to determine the association between self-perceived HIV risk (categorised as "not at risk", at "low risk", at "high risk" and "didn't know") and being sexually active and testing HIV-positive, controlling for socio-demographic, behavioural and health-related factors.Results: Of the 435 respondents, 9.4% perceived themselves as at high risk of HIV infection, 18.9% as at low risk and 53.6% believed they were not at risk of HIV. Most respondent who perceived themselves as at low risk or not-at-risk at all of HIV were not sexually active. Older adults that were sexually active were more likely to consider themselves as at high risk of acquiring HIV (relative risk ratio [RRR] 2.05; 95% confidence interval (CI) 1.05-4.00; p = 0.036), as well as to test HIV positive (RRR 10.5; 95% CI 3.8-29.1; p < 0.001). Self-perceived HIV risk was significantly associated with age, sex, population group, and a greater awareness about HIV and how it is transmitted.Conclusions: Older persons who perceived themselves as at high risk of HIV were closely associated with sexual activity and testing HIV positive. Therefore, there is an urgent need for older persons, particularly those who remain sexually active, to screen and test for HIV routinely. Furthermore, there should be policy and programme interventions, such as the development of a simple risk-assessment tool for older adults to determine their risk for HIV. Older persons have been neglected in sexual health and HIV programmes. There is, therefore, a need to encourage older persons to take up appropriate HIV risk reduction and prevention behaviours.

Sex Differences in HIV Testing among Older Adults in Sub-Saharan Africa: A Systematic Review

Background

Despite being sexually active and engaging in risky sexual behaviours similar to young adults, older adults (50 years or older) are less likely to receive HIV testing, and disaggregated data are still scarce about HIV prevention and treatment in this vulnerable population in sub-Saharan Africa (SSA). This systematic review is aimed at examining sex differences in HIV testing and counseling (HTC) among older adults in SSA.

Methods

A systematic search of four databases, namely, MEDLINE (Ovid), EMBASE (Ovid), Web of Science, and Global Health, was conducted from 2000 to January 2020. The primary outcome of interest for this study was gender differences in HTC among older adults in SSA. Observational studies including cross-sectional, retrospective, and prospective cohort studies were included. Eligible studies must have reported sex differences in HIV testing uptake in a standard HTC service among older adults in SSA.

Results

From the database search, 4143 articles were identified. Five studies were ultimately included in the final review. Of the 1189 participants, 606 (51.1%) and 580 (48.9%) were female and male, respectively. The review findings suggested that both men and women preferred HTC providers that are the same sex as them with women additionally preferring a provider who is also of a similar age. Men and women differed in their pathways to getting tested for HIV. The review documented mixed results with regard to the associations between sex of older adults and uptake of HTC. Older adult HTC uptake data are limited in scope and coverage in sub-Saharan Africa.

Conclusion

This review revealed shortage of evidence to evaluate optimum HTC utilization among older adults. Few studies examined sex differences in HIV testing among older adults in the region. There is a need for stakeholders working in the area of HIV prevention and treatment to focus on older adult health utilization evidence organization, disaggregated by age and sex. Hence, high-quality research designs are needed on the topic in order to generate good quality evidence for targeted interventions to improve HTC among older adults in sub-Saharan Africa.

Social Cognitive Theory as a Theoretical Framework to Predict Sexual Risk Behaviors among Older Adults

OBJECTIVES

Older adults vary in their safe and unsafe sexual behaviors. While researchers are beginning to understand more about the sexual and intimate expression of older adults, only recently are they beginning to understand how older adults make decisions about sexual risk. Bandura's social cognitive theory offers a frame for understanding how self-efficacy, environmental factors, and goal motivation are related to sexual risk behaviors for older adults, including the interplay between these variables.

METHODS

Using a diverse sample of older adults (n = 720) age 50+ years, social cognitive theory was modeled to determine the relationship between environment variables (age, gender, and sexual health conversations with practitioners), behavioral variables (self-efficacy), and cognitive variables (importance of sexual wellness goals) with the outcome variable of sexual risk behaviors.

RESULTS

Self-efficacy had an indirect effect on sexual risk via sexual wellness goal motivation. Healthcare provider conversations had both direct and indirect effects on older adults' sexual risk through sexual wellness goal motivation. Models were similarly predictive for older men and women.

CONCLUSIONS

Sexual risk behaviors among older adults are more influenced by environmental factors in their healthcare settings and their perception and prioritization of sexual wellness goals.

CLINICAL IMPLICATIONS

Providers play a key role in initiating and maintaining sexual health discussions with older patients, potentially mitigating sexual risk and bolstering self-efficacy.

The HIV prevalence in older men who have sex with men in Western & Central Europe and North America-a meta-analysis

The age of patients living with human immunodeficiency virus (HIV) is increasing and the greatest proportion of aged HIV patients occurred in Western and Central Europe and North America (WCENA). In aged HIV patients in WCENA, older MSM is the main population. The aim of our study was to evaluate the HIV prevalence in older MSM in WCENA. A meta-analysis was conducted. We searched Medline, Embase, PsycINFO, Web of Science, Cochrane library, Ageline databases, and government websites. Studies that estimated HIV prevalence in older MSM in WCENA were selected. The pooled HIV prevalence and odds ratio (OR) of the risk of living with HIV in older MSM were calculated. In total of 23000 records were initially records were identified and 12 records were included. The total sample size of older MSM was 6118. The pooled HIV prevalence in older MSM in WCENA was 26% (95% CI 18%-33%), which was much higher than that in younger MSM (18%, 95% CI 14%-21%). Notably, the HIV prevalence in older MSM has been continuously increasing in the past two decades in WCENA, raising from 16% to 33%. The pooled OR for older MSM to be living with HIV was 1.68 compared to younger MSM. The HIV prevalence in older MSM in WCENA is disproportionately high, with a continuously increasing trend in the past two decades. Older MSM also carry significantly higher risk of living with HIV than younger MSM.

Prevalence of HIV/AIDS Among Elderly People and Associated Factors in Habru Woreda, Amhara Region, Northeast Ethiopia

INTRODUCTION

Sub-Saharan African countries are the most affected region by HIV/AIDS. Data from Demographic and Health Survey (DHS) indicated that in Ethiopia older adults who are HIV positive were 2.1% which accounted 17.7% from all HIV positive people aged ≥15. Scarce data are available regarding the prevalence of HIV and associated factors among elderly peoples in Habru district.

OBJECTIVE

To assess the prevalence of HIV and associated factors among older people ≥50 years' age in the study area.

METHODS

A community-based cross-sectional study was employed. A multi-stage simple random sampling technique was employed and a total of 1689 study subjects were involved. Data were collected by trained health professionals and analyzed using descriptive and analytical statistics. Binary and multivariate logistic regressions were used to identify factors associated with the prevalence of HIV. P-value ≤0.05 was considered statistically significant.

RESULTS

Total of 1689 participants were involved and tested for HIV sero-status of which 51.1% were females and the mean age was 62.4±12.34 years. The prevalence for HIV+ was 6.2%. From the multivariate regression model, significant association between prevalence and condom use at last sexual intercourse [AOR= 11.099; 95% CI (2.357,52.268)], condom use at high-risk sexual intercourse [AOR=0.088; 95% CI (0.020, 0.398)], marital status [AOR= 0.409; 95% CI (0.252,0.666)], religion [AOR= 0.431; 95% CI (0.241, 773)], types of previous work [AOR= 0.301; 95% CI (0.117, 0.770)], older people self-perception to risk of HIV infection [AOR= 3.731; 95% CI (2.280, 6.104)], care for HIV infected and non-infected grand children [AOR= 0.434; 95% CI (0.235, 800)], presence of care and support program [AOR= 6.128; 95% CI (1.532, 24.514)] was noticed.

CONCLUSION

The prevalence of HIV in Habru was higher (6.2%) than the national level (2.1%) and efforts should be concentrated on designing new HIV intervention programs targeting older people aged ≥50years.

Newly diagnosed cases of HIV in those aged 50 years and older and those less than 50: 2008-2017

BACKGROUND

Canada's population is aging, with nearly forty percent of Canadians aged 50 years or more. As the population ages, unique challenges related to health are becoming evident, including increasing rates of sexually transmitted and bloodborne infections. Understanding the epidemiology of HIV in older adults is important to guide prevention and control programs.

OBJECTIVE

To assess trends in newly diagnosed cases of HIV in Canada among those aged 50 years and older (≥50 years) and those aged less than 50 (<50 years), and to compare their basic demographic characteristics and exposure categories for the period of 2008 to 2017.

METHODS

National surveillance of HIV is conducted by the Public Health Agency of Canada through voluntary submission of data by provincial/territorial public health authorities. Descriptive analyses were conducted on reported cases of HIV between January 1, 2008, to December 31, 2017 to compare the demographic profiles and exposure category for the two age groups.

RESULTS

Between 2008 and 2017, the proportion of newly diagnosed HIV cases among those ≥50 years increased from 15.1% to 22.8%. The HIV diagnosis rates for both older males and older females increased over time, with a relatively higher increase for females. A higher proportion of newly diagnosed HIV cases were male in the older group (81.2%) compared to the younger group (74.6%). Among both older and younger males, the most common exposure category for HIV was being gay, bisexual and other men who have sex with men (gbMSM), followed by heterosexual contact and injection drug use; however, the relative proportions varied by age with the gbMSM category being higher in the <50 group.

CONCLUSION

In Canada, over 20% of all newly diagnosed cases of HIV are now in people 50 years of age and older. HIV testing and prevention initiatives, historically aimed at younger populations, may not have the same impact for older populations. These data can be used to inform future public health actions designed to address HIV in older populations.

Exploring HIV concern in a population of Dominican American women midlife and older

BACKGROUND

The feminization and ethnic diversification of HIV infection, has resulted in a call for gender- and culture-specific prevention strategies for at-risk groups including Latinos in the United States. The steadily changing demographic profile of the AIDS epidemic challenges prevention strategies to remain relevant and up-to-date, particularly in populations of women midlife and older where an understanding of risk remains under explored. As the CDC requests country-specific HIV risk profiles for Latino communities in the US, understanding the socio-economic, behavioral and personal risk reasons of HIV risk for older Dominican women is critical for prevention.

METHODS

We conducted focus group discussions informed by the Theory of Gender and Power (TGP). The three constructs of the TGP: 1) Affective influences/social norms; 2) Gender-specific norms and. 3) Power and Authority guided the thematic analysis and identified themes that described the socio-cultural and contextual reasons that that contribute to perceptions of HIV risk.

RESULTS

Sixty Dominican American women ages 57-73 participated in our focus group discussions. Sexual Division of Labour: 1) Economic Dependence; 2) Financial Need and 3) Education and Empowerment. Sexual Division of Power: 4) HIV Risk and 5) Relationship Dynamics. Cathexis: Affective Influences/Social Norms: 6) HIV/AIDS Knowledge and 7) Prevention and Testing. Importantly, participants were concerned about partner fidelity when visiting the Dominican Republic, as the country accounts for the second highest HIV rates in the Caribbean.

CONCLUSIONS

Our results confirm previous findings about perceptions of HIV risk and provide additional insight into aging-related aspects of HIV risk for Latino women midlife and older.

Higher Risks of Virologic Failure and All-Cause Deaths Among Older People Living with HIV in Chongqing, China

Older people living with HIV (PLWH) may have delayed diagnosis and access to care and therefore have poorer disease outcomes. Little is known about HIV care and disease outcomes among older PLWH in China. This retrospective cohort study used data from all adult HIV/AIDS cases during 1988-2017 in Chongqing, China from two national databases. We compared demographic and behavioral profiles, HIV care, virologic suppression, and mortality between two age groups of 18-49 and ≥50 years. Multivariate logistic and cox regression analyses were used to calculate adjusted odds ratio (AOR) and adjusted hazard ratio (AHR) among older versus younger PLWH. Of 46,580 adult HIV/AIDS cases, 76.1% were men and 38.2% were 50 years of age or older. The proportion of older cases in men increased from 2.4% in 2002 to 51.8% in 2017, and in women from 3.3% to 57.9%. Older PLWH had a lower CD4 count than their younger counterparts at HIV diagnosis (median 323 vs. 391 cells/μL; p < .001). The average time from HIV diagnosis to initiation of antiretroviral therapy (ART) were 6.3 months among older and 12.8 months among younger PLWH (p < .001). Nearly one tenth (9.6%) had virologic failure within 12 months of ART initiation, and the odds of virologic failure among older PLWH was 80% higher [AOR 1.8; 95% confidence interval (CI), 1.1-3.0] than among younger ones after controlling for calendar year of initiating ART and other covariates. The mortality rate within 12 months of initiating ART was 9.8 deaths per 100 person years, and the risk of mortality among older PLWH was three times among younger ones (AHR, 3.1; 95% CI, 2.1-4.6). Older people represented an increasing proportion of new HIV/AIDS cases and were more likely to have virologic failure and mortality within 12 months of ART initiation.

Social representations of HIV/AIDS by older people and the interface with prevention

OBJECTIVE

To apprehend the social representations elaborated by older people about HIV/AIDS and to understand how they relate to the prevention of HIV infection.

METHOD

Descriptive and qualitative research based on the Theory of Social Representations with 42 older people assisted at primary care. Data were produced through in-depth interviews with a semi-structured instrument, processed in the IRaMuTeQ software, and analyzed by means of the descending hierarchical classification.

RESULTS

Five classes emerged: "HIV/AIDS: a problem of young people"; "Quality of life improvement for people living with HIV/AIDS"; "Vulnerability to HIV/AIDS among heterosexual women in a stable union"; "HIV/AIDS Information Network: process of creation and transformation of social representations" and "Prevention versus stigma".

FINAL CONSIDERATIONS

The social representations that older people have about HIV/AIDS influence the adoption of preventive measures negatively because stigma is present and HIV/AIDS is attributed to young men, and to men who have sex with other men.

HIV Knowledge and Risk Behaviors Among Older Church-Affiliated Blacks

There is an emerging population of older adults living with HIV, and among them, Black older adults experience the greatest burden of the disease. This is a growing public health concern, as older adults are disproportionately diagnosed at a later stage of the disease, while reporting similar risk factors as younger adults. It has also been shown that the Black Church is well positioned to offer health screenings. Thus, this study aimed to assess HIV knowledge, beliefs, and risk behaviors of older church-affiliated Black adults. Data were collected from a sample of Black adults (N = 543) from four predominately Black churches in Kansas City, MO. Participants were surveyed on measures assessing demographic characteristics, HIV knowledge and attitudes, and HIV testing and risk behaviors. Results indicated that compared to younger Black adults, Black older adults were less knowledgeable about the transmission of HIV and were less willing to be tested for HIV in church settings. However, there was no significant difference on the perceived seriousness of HIV in the community. Results further showed that Black older adults were less likely to use condoms/barriers during the past 6 months and over their lifetime. We discuss the implications of results for HIV intervention programs.

Perceived sexual self-control and condom use with primary and casual sex partners: age and relationship agreement differences in a Portuguese sample

OBJECTIVE

Consistent condom use is still not ideal. Research showed that perceived sexual self-control is associated with greater likelihood of using condoms. However, this association seems to vary according to age and relationship agreement (i.e. non-consensual non-monogamy, NCNM vs. consensual non-monogamy, CNM).

DESIGN

Cross-sectional study with 307 heterosexual users of a dating web site for romantically involved individuals (81.8% men; M_age = 42.24, SD = 9.65, range: 23-76 years). All individuals were in a romantic relationship (M_length = 13.47 years, SD = 9.39).

MEASURES

Demographic information, perceived sexual self-control, condom use frequency (casual sex partners; primary partner in the last 3 months) and relationship agreement.

RESULTS

Independently of relationship agreement, perceived sexual self-control was positively associated with condom use frequency with casual sex partners among younger and middle age participants, but not older ones (>49 years). Regarding the primary partner, a similar pattern emerged for CNM participants. In contrast, no significant association between perceived sexual self-control and condom use frequency with the primary partner emerged for NCNM individuals, regardless of age.

CONCLUSION

Our findings can inform evidence-based strategies to promote consistent condom use as an effective behaviour to prevent sexually transmitted infections, especially among older and NCNM individuals.

Dysregulation in Genital Tract Soluble Immune Mediators in Postmenopausal Women Is Distinct by HIV Status

A rise in new HIV diagnoses among older adults is characterized by poor prognosis and reduced survival times. Although heterosexual transmission remains the main route of infection in women, little is known regarding immune functions in the genital tract of postmenopausal women, especially those who are HIV positive. Furthermore, effects of hormone replacement therapy (HRT) on the genital tract immune system are unclear. Using the Women's Interagency HIV Study repository, we obtained cervical-vaginal lavage (CVL) samples from premenopausal and postmenopausal HIV-positive and HIV-negative women, some of whom were on HRT. Samples were assayed for interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-α, secretory leukocyte protease inhibitor (SLPI), Elafin, human beta defensin-2 (HBD2), and macrophage inflammatory protein (MIP)-3α using ELISA. Anti-HIV activity in CVL was measured using TZM-bl indicator cells. Among HIV-positive women, the plasma viral load was significantly higher and CD4 count was significantly lower in postmenopausal compared with premenopausal women. Postmenopausal women, irrespective of HIV status, had significantly lower levels of HBD2 compared with premenopausal women. Among the HIV-negative individuals, postmenopausal women had significantly lower levels of MIP-3α, IL-6, and SLPI compared with premenopausal women. In contrast, HIV-positive postmenopausal women had significantly higher levels of TNF-α compared with HIV-positive premenopausal women. In most cases, HRT groups resembled the postmenopausal groups. No significant differences in anti-HIV activity by menopausal or by HIV status were noted. Our findings indicate that the female genital tract immune microenvironment is distinct by menopausal status and HIV status. Further studies are needed to assess the risk of HIV acquisition/transmission in this population.

Evaluating HIV Educational Materials for Older People

OBJECTIVE

To address the gap in knowledge about HIV risk reduction materials that target older adults. This review offered a comprehensive and rigorous examination of HIV risk reduction education materials that targeted older adults in the United States, assessing the gap in their coverage and content.

METHOD

A cross-sectional review of both print and Internet sources from state departments of public health, state and area agencies on aging, and web resources that targeted older populations was performed.

RESULTS

Of 29 health departments and 13 state and area agencies on aging that responded to the request, there were 9 HIV education materials identified that targeted older people. Of those materials, only 2 addressed the majority of aging-specific recommendations made from a previous study that described important HIV risk reduction information.

DISCUSSION

Recommendations are made about dissemination ideas to increase awareness and utilization of HIV educational materials.

HIV testing and counselling experiences: a qualitative study of older adults living with HIV in western Kenya

BACKGROUND

Finding HIV infected persons and engaging them in care is crucial in achieving UNAIDS 90-90-90 targets; diagnosing 90% of those infected with HIV, initiating 90% of the diagnosed on ART and achieving viral suppression in 90% of those on ART. To achieve the first target, no person should be left behind in their access to HIV testing services. In Kenya, HIV prevention and testing services give less emphasis on older adults. This article describes HIV testing experiences of older adults living with HIV and how their age shaped their interaction and treatment received during HIV testing and diagnosis.

METHODS

We conducted a qualitative study in two HIV clinics (rural and urban) in western Kenya, and recruited 57 HIV infected persons aged ≥50 years. We conducted in depth interviews (IDIs) with 25 participants and 4 focus group discussions (FGDs) with a total of 32 participants and audio recorded all the sessions. Participants recruited were aged between 54 and 79 years with 43% being females. We transcribed audio records and analyzed the data using thematic content analysis method.

RESULTS

Older persons' experiences with HIV testing depended on where they tested (hospital or community setting); whether they actively sought the testing or not; and the age and gender of the healthcare provider who conducted the test. Participants expressed concerns with ageist discrimination when actively seeking HIV care testing services in hospital settings, characterized by providers' reluctance or refusal to test. The testing and counseling sessions were described as short and hurried within the hospital settings, whereas the interactions with service providers in home-based testing were experienced as appropriate and supportive. Participants in this study expressed preference for healthcare providers who were older and of similar gender.

CONCLUSION

HIV testing services are still not tailored to target older adults' needs in our setting resulting in late diagnosis among older persons. We argue that a scale-up of community level testing services that provide adequate testing and counselling time and actively reach out to older adults is key to attaining the UNAIDS targets of having 90% of PLWH know their status.

"I'm in control: I'm not stumbling in the dark anymore": Midlife women's experiences of successfully negotiating safer sex with new partners

The rates of STIs in women over 45 years have been steadily increasing in Australia and other Western countries. Traditionally sexual health and STI prevention and research has positioned young people as the priority population; to date, insufficient attention has been paid to the sexual health of women over 45 years. Using a strengths-based approach, the objective of this study was to explore the factors and mechanisms that enable Australian women aged 45 to 64 years to successfully negotiate safer sex practices in new relationships. Interpretative Phenomenological Analysis (IPA) was employed for an in-depth exploratory study of a sample of eight women. Three broad themes emerged: being informed, being prepared, and being empowered. These findings provide a valuable insight into how we can initiate change and support safer sex practices for this target group.

Unsafe Sexual Behavior Among Gay/Bisexual Men in the Era of Combination Antiretroviral Therapy (cART)

The aim of this study was to determine the association between psychosocial determinants of unprotected receptive anal intercourse (URAI) and unprotected insertive anal intercourse (UIAI). Data from 417 HIV positive men who have sex with men (MSM) in the Multicenter AIDS Cohort Study from April 1999 to March 2012 were analyzed and adjusted odds were calculated. It was found that 66% (n = 277) and 72% (n = 299) reported any UIAI or URAI over follow-up, respectively. Cumulative cART-years (median = 5.30 years) was associated with 33 and 47% increases in UIAI and URAI, respectively. Not having reduced concern about HIV transmission (UIAI: OR 0.37, p-value = 0.0004; URAI: OR 0.57, p-value = 0.04), increased safe sex fatigue (UIAI: OR 2.32, 95% p-value = 0.0002; URAI: OR 1.94, p-value = 0.003), and sexual sensation seeking (UIAI: OR 1.76, p-value = 0.002; URAI: OR 1.56, p-value = 0.02) were associated with UIAI and URAI. Serosorting was associated with UIAI (OR 6.11, p-value < 0.0001) and URAI (OR 6.80, p-value < 0.0001). Findings suggest that negative attitudes about HIV transmission are sustained among older men who have sex with men.

A Comparison of Actual and Perceived Sexual Risk Among Older Adults

Sexual risk among older adults (OAs) is prevalent, though little is known about the accuracy of sexual risk perceptions. Thus, the aim was to determine the accuracy of sexual risk perceptions among OAs by examining concordance between self-reported sexual risk behaviors and perceived risk. Data on OAs aged 50 to 92 were collected via Amazon.com's Mechanical Turk. Frequency of sexual risk behaviors (past six months) were reported along with perceived risk, namely, sexually transmitted infection (STI) susceptibility. Accuracy categories (accurate, underestimated, overestimated) were established based on dis/concordance between risk levels (low, moderate, high) and perceived risk (not susceptible, somewhat susceptible, very susceptible). Approximately half of the sample reported engaging in vaginal (49%) and/or oral sex (43%) without a condom in the past six months. However, approximately two-thirds of the sample indicated they were "not susceptible" to STIs. No relationship was found between risk behaviors and risk perceptions, and approximately half (48.1%) of OAs in the sample underestimated their risk. Accuracy was found to decrease as sexual risk level increased, with 93.1% of high-risk OAs underestimating their risk. Several sexual risk behaviors are prevalent among OAs, particularly men. However, perception of risk is often inaccurate and warrants attention.

Sexual Behaviors and HIV Status: A Population-Based Study Among Older Adults in Rural South Africa

OBJECTIVE

To identify the unmet needs for HIV prevention among older adults in rural South Africa.

METHODS

We analyzed data from a population-based sample of 5059 men and women aged 40 years and older from the study Health and Aging in Africa: Longitudinal Studies of INDEPTH Communities (HAALSI), which was carried out in the Agincourt health and sociodemographic surveillance system in the Mpumalanga province of South Africa. We estimated the prevalence of HIV (laboratory-confirmed and self-reported) and key sexual behaviors by age and sex. We compared sexual behavior profiles across HIV status categories with and without age-sex standardization.

RESULTS

HIV prevalence was very high among HAALSI participants (23%, 95% confidence interval [CI]: 21 to 24), with no sex differences. Recent sexual activity was common (56%, 95% CI: 55 to 58) across all HIV status categories. Condom use was low among HIV-negative adults (15%, 95% CI: 14 to 17), higher among HIV-positive adults who were unaware of their HIV status (27%, 95% CI: 22 to 33), and dramatically higher among HIV-positive adults who were aware of their status (75%, 95% CI: 70 to 80). Casual sex and multiple partnerships were reported at moderate levels, with slightly higher estimates among HIV-positive compared to HIV-negative adults. Differences by HIV status remained after age-sex standardization.

CONCLUSIONS

Older HIV-positive adults in an HIV hyperendemic community of rural South Africa report sexual behaviors consistent with high HIV transmission risk. Older HIV-negative adults report sexual behaviors consistent with high HIV acquisition risk. Prevention initiatives tailored to the particular prevention needs of older adults are urgently needed to reduce HIV risk in this and similar communities in sub-Saharan Africa.

HIV and Aging Research in Women: An Overview

This paper reviews some background issues as a foundation to place the ensuing supplement papers of this special issue section in context. The articles in this special supplement issue deepen and expand our understanding of biomedical, neurocognitive, and psychosocial aspects involved in human immunodeficiency virus (HIV) of older women, primarily through the use of the Women's Interagency HIV Study (WIHS) prospective cohort study. As it relates to research on the intersection between HIV and aging in women, we discuss (i) epidemiology as introduction, (ii) the cohort study design featuring the WIHS, (iii) definitions, (iv) models, and (v) section articles.

Caring for Older Adults with the Human Immunodeficiency Virus

Increasing proportions of older adults are living with the human immunodeficiency virus (HIV). It is estimated that more than 50% of individuals with HIV in the United States are aged 50 and older. Part of this group consists of individuals who have aged with chronic HIV infection, but a large proportion also results from new HIV diagnosis, with approximately 17% of new HIV diagnoses in 2013 occurring in individuals aged 50 and older. Although many of the recommendations on management of HIV infection are not age-specific, individuals with HIV aged 50 and older differ from their younger counterparts in many aspects, including immune response to antiretroviral therapy, multimorbidity, antiretroviral toxicities, and diagnostic considerations. This article outline these differences, offers a strategy on how to care for this unique population, and provides special considerations for problem-based management of individuals with HIV aged 50 and older.

Reduced levels of genital tract immune biomarkers in postmenopausal women: implications for HIV acquisition

BACKGROUND

Rates of HIV infections are increasing in older adults. Although it is known that the HIV/AIDS epidemics affects women disproportionately, little is known regarding immune functions in the genital tract of postmenopausal women, as relevant to HIV susceptibility.

OBJECTIVE

The objective of the study was to compare levels of female reproductive tract immune mediators that are important for HIV-associated immune responses as well as intrinsic anti-HIV activity in the cervical vaginal lavages collected from HIV-negative pre- and postmenopausal women.

STUDY DESIGN

Cervical vaginal lavage from 20 premenopausal and 20 postmenopausal women were assayed for interleukin-6, interleukin-8, tumor necrosis factor-α, secretory leukocyte protease inhibitor, elafin, human β-defensin-2, and macrophage inflammatory protein-3α using standard enzyme-linked immunosorbent assays. Anti-HIV activity of cervical-vaginal lavage was measured using TZM-bl indicator cells against HIV-1 IIIB and BaL. Whereas each postmenopausal woman provided only 1 sample, each premenopausal woman provided 3 samples, during proliferative, ovulatory, and secretory stages, based on menstrual dates.

RESULTS

We observed significantly lower levels of tumor necrosis factor-α, MIP-3α, secretory leukocyte protease inhibitor, elafin, and human β-defensin-2 in cervical vaginal lavage from postmenopausal women compared with premenopausal women. Inhibition of HIV-1 infection was observed for both pre- and postmenopausal women, but cervical vaginal lavage from postmenopausal women showed significantly higher inhibition against HIV-1 BaL after adjusting for total protein concentration, genital pH, and reproductive tract infections. No change in mediators or HIV inhibition was observed through the stages of menstrual cycle. In addition, we observed that postmenopausal women with reproductive tract infections had significantly higher levels of tumor necrosis factor-α and significantly lower levels of interleukin-8, which were not observed in premenopausal women.

CONCLUSION

Our findings suggest that female reproductive tract immune microenvironment is distinct in HIV-negative postmenopausal women. Further studies are needed to assess the risk of HIV acquisition/transmission in this population.

Disclosure and Self-Efficacy Among HIV-Positive Men Who Have Sex with Men: A Comparison Between Older and Younger Adults

Men who have sex with men (MSM) continue to be disproportionately affected by HIV in the US. HIV among older adults also continues to be an important public health problem. Age is associated with disclosure of HIV serostatus and self-efficacy for condom use. However, studies examining self-efficacy and disclosure among older MSM (age 50 and older) living with HIV are lacking. The aim of this study was to assess the associations between being 50 and older, and disclosure behaviors, intentions and attitudes, and self-efficacy for condom use, disclosure, and negotiation for safer sex practices among HIV-positive MSM. Data were gathered from 340 participants at the baseline assessment of a longitudinal disclosure intervention study. Linear regression was used to determine the association between being older (age 50 and older) and disclosure behaviors, intentions and attitudes, and self-efficacy for condom use, disclosure, and negotiation for safer sex practices. After adjusting for time since diagnosis and number of sexual partners, MSM aged 50 and older scored lower in disclosure behavior (β = -7.49; 95% CI: -14.8, -0.18) and in self-efficacy for negotiation of safer sex practices (β = -0.80; 95% CI: -1.57, -0.04) compared to MSM 18-34 years. Intervention and prevention programs should endeavor to improve disclosure and self-efficacy for negotiating safer sex practices among older HIV-positive MSM. More health care providers should initiate sexual health discussions, especially among older HIV-positive MSM populations, which may help to improve their disclosure behavior and self-efficacy for negotiating safer sex practices.
