Sexual Risk and Protective Behaviors Among Reproductive-Aged Women in the United States

Modeling the impact of changing sexual behaviors with opposite-sex partners and STI testing among women and men ages 15-44 on STI diagnosis rates in the United States 2012-2019

Objective

To estimate the potential contributions of reported changes in frequency of penile-vaginal sex (PVS), condom use and STI screening to changes in gonorrhea and chlamydial diagnoses from 2012 to 2019.

Methods

An agent-based model of the heterosexual population in the U.S. simulated the STI epidemics. Baseline was calibrated to 2012 diagnosis rates, testing, condom use, and frequency of PVS. Counterfactuals used behaviors from the 2017-2019 NSFG, and we evaluated changes in diagnosis and incidence rates in 2019.

Results

Higher testing rates increased gonorrhea and chlamydia diagnosis by 14% and 13%, respectively, but did not reduce incidence. Declining frequency of PVS reduced the diagnosis rate for gonorrhea and chlamydia 6% and 3% respectively while reducing incidence by 10% and 9% respectively. Declining condom use had negligible impact on diagnosis and incidence.

Conclusion

Understanding how changing behavior drives STI incidence is essential to addressing the growing epidemics. Changes in testing and frequency of PVS likely contributed to some, but not all, of the changes in diagnoses. More research is needed to understand the context within which changing sexual behavior and testing are occurring.

Condom use and HIV testing among adults in Switzerland: repeated national cross-sectional surveys 2007, 2012, and 2017

BACKGROUND

Monitoring of HIV and sexually transmitted infection (STI) prevention is important for guiding national sexual health programmes for both the general population and key populations. The objectives of this study were to examine trends and patterns of condom use at last intercourse and lifetime HIV testing in 2007, 2012 and 2017 in Switzerland, and to explore factors associated with these behaviours in men and women with opposite-sex partners and with same sex partners.

METHODS

We analysed data from the 2007, 2012 and 2017 Swiss Health Survey. For each time point, outcome and population group, we conducted a descriptive analysis of weighted data and conducted multivariable logistic regression to obtain adjusted odds ratios (aOR) with 95% confidence intervals (CI) and compared outcomes between the timepoints.

RESULTS

In total, 46,320 people were interviewed: 21,847 men and 23,141 women, who reported having sex only with partners of the opposite sex, 633 men who reported sex with a male partner and 699 women who reported sex with a female partner. Among the three surveys the prevalence of condom did not change but varied from 22 to 26% of men and 15 to 21% in women with only opposite-sex partners (aOR men, 0.93, 95% CI 0.82, 1.06; women 0.98, 95% CI 0.86 to 1.11). In men with any same sex partner the prevalence of condom use was 40% in 2007, 33% in 2012 and 54% in 2017 (aOR 1.80, 95% CI 0.97, 3.34). In multivariable analysis, the factor most strongly associated with condom use was sex with an occasional partner at last intercourse. HIV testing ever increased across all three survey years in people with opposite sex partners: 2017 vs. 2007, aOR men with only opposite-sex partners 1.64 (95% CI 1.49, 1.82), women with only opposite-sex partners 1.67 (1.51, 1.85), men with any same sex partner 0.98 (0.49, 1.96), women with any same sex partner 1.31 (0.74, 2.30).

CONCLUSIONS

Monitoring of condom use, and HIV testing should continue and contribute to the development of the national sexual health programme. Stronger promotion of condoms for people with opposite-sex partners might be needed, since overall condom use at last intercourse has not changed since 2007.

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.

Changes in Sexual Behaviors with Opposite-Sex Partners and Sexually Transmitted Infection Outcomes Among Females and Males Ages 15-44 Years in the USA: National Survey of Family Growth, 2008-2019

Rates of reported gonorrhea and chlamydial infections have increased substantially over the past decade in the USA and disparities persist across age and race/ethnicity. We aimed to understand potential changes in sexual behaviors, sexual network attributes, and sexually transmitted infection (STI) screening that may be contributing to these trends. We analyzed data from 29,423 female and 24,605 male respondents ages 15-44 years from the National Survey of Family Growth, 2008-2019. We used survey-weighted linear or logistic regression to evaluate linear temporal trends in sexual behaviors with opposite-sex partners, network attributes, and STI testing, treatment, and diagnosis. Significant declines were observed in condom use at last vaginal sex, mean number of vaginal sex acts, proportion of condom-protected sex acts in the past 4 weeks, and racial/ethnic homophily with current partners among males and females from 2008-2010 through 2017-2019. Among males, mean number of female partners in the past 12 months and concurrency also declined, while the percent reporting ever having sex with another male increased. Past-year testing for chlamydia and any STI increased among females. Research is needed to understand how these changes interact and potentially contribute to increasing reported gonorrhea and chlamydia diagnoses and identify avenues for future intervention.

Self-Reported Sexually Transmitted Infections After Incarceration in Women with or at Risk for HIV in the United States, 2007-2017

Background: U.S. women who have been incarcerated report high rates of sexual risk behavior and sexually transmitted infections (STIs). Materials and Methods: We estimated the effect of incarceration on the time to first incident STI in a multicenter cohort of U.S. women with or at risk for HIV. We used marginal structural models to compare time to first self-reported gonorrhea, chlamydia, or trichomonas infection for nonincarcerated women and incarcerated women. Covariates included demographic factors, HIV status, sex exchange, drug/alcohol use, and prior incarceration. Results: Three thousand hundred twenty-four women contributed a median of 4 at-risk years and experienced 213 first incident STI events. The crude incidence of STIs was 3.7 per 100 person-years for incarcerated women and 1.9 per 100 person-years for nonincarcerated women. The weighted hazard ratio for incident STIs was 4.05 (95% confidence interval: 1.61-10.19). Conclusion: Women with or at risk for HIV in the United States who have recently experienced incarceration may be at increased STI risk.

A Systematic Review Exploring Racial Disparities, Social Determinants of Health, and Sexually Transmitted Infections in Black Women

OBJECTIVE

To explore and describe racial disparities, the role of social determinants of health, and individual risk behaviors among Black women as related to sexual health and/or sexually transmitted infections (STIs).

DATA SOURCES

Electronic resource databases used were PubMed, CINAHL, and Google Scholar. Peer-reviewed articles published during 2010 to 2020 were considered.

STUDY SELECTION

Thirty-two studies met the criteria and included data for a total of 18,904 Black women.

DATA EXTRACTION

Data were extracted from each study using the subheadings author (year), purpose, design, sample demographics and setting, key measures, key findings, and quality assessment. In addition, PRISMA-E and PROGRESS-Plus guided data extraction to illustrate health inequity.

DATA SYNTHESIS

Black women who were more likely to report having an STI over the course of their lifetime engaged in behaviors associated with greater risk, the most common of which were unprotected sex, disproportionate partner power, and substance abuse. The primary social determinants of health associated with increased risk were lower income and lower levels of education. Black women were less likely to discuss or feel comfortable discussing their sexual health with health care providers. By contrast, engagement in safe sexual practices stemmed from internal, social, and relationship factors.

CONCLUSION

Identifying Black women who are at risk of contracting an STI is essential in driving clinical decision-making. Health care providers should be cognizant of the long-standing mistrust that Black women have of health care providers and, therefore, work to establish positive respectful and trusting relationships with open communication.

Safer Sex Self-Efficacy Among Women With Experiences of Intimate Partner Violence

Women who have experienced intimate partner violence (IPV) are more likely to engage in risky sexual behaviors that increase the likelihood of adverse sexual health outcomes, including HIV acquisition. This study explored key predictors of safer sex self-efficacy in a sample of racially/ethnically diverse abused women. A total of 173 women were recruited from domestic violence agencies and completed a battery of measures that assessed risk factors associated with HIV risk. Both individual- and relationship-level predictors of safer sex self-efficacy were examined, including IPV, partner dependence, HIV knowledge, condom attitudes, self-esteem, and alcohol use. Hierarchical linear regression analysis results indicated several key predictors for safer sex self-efficacy, including IPV (B = -0.01, p < .05), partner dependence (B = -0.45, p < .001), condom attitudes (B = 0.63, p < .001), and alcohol use (B = - 0.24, p < .05). It is evident that a number of individual- and relationship-level factors affect the degree of safer sex self-efficacy among abused women. In work with this population, researchers and clinicians should intentionally attend to the identified predictors to most effectively address the needs of these women.

Missed Opportunities for HIV Prevention in Perinatal Care Settings in the United States

Universal opt-out HIV screening in pregnancy is an essential intervention toward eliminating perinatal HIV transmission in the US. However, it fails to identify pregnant people who are HIV negative at the time of testing but are at ongoing risk for HIV acquisition. Those of us involved in caring for women living with HIV are acutely aware of the many diagnoses of HIV that might have been prevented if only a partner had been tested for HIV or preexposure prophylaxis (PrEP) had been offered to a patient. This perspective article will review current recommendations and evidence-based interventions to evaluate missed opportunities for HIV prevention in US perinatal care settings. We identified three barriers to implementation of HIV prevention strategies during pregnancy and breastfeeding: (1) HIV risk for women is underestimated and poorly defined in clinical practice; (2) Partner testing is challenging and implementation studies in the US are lacking; and (3) PrEP remains underutilized. In March 2020, the National Perinatal HIV Hotline convened a group of clinicians and researchers specializing in perinatal HIV care to a case-based discussion of missed opportunities in perinatal HIV prevention. From our review of the literature via PubMed search as well as expert opinions gathered in this discussion, we make recommendations for addressing these barriers.

Improving Research, Policy, and Practice to Address Women's Sexual and Reproductive Health Care Needs During Emerging Adulthood

Women in the period of emerging adulthood (18-25 years of age) have the greatest rates of unintended pregnancy and sexually transmitted infections. Despite this disproportionate risk, women's sexual and reproductive health needs during emerging adulthood are poorly understood. As a result, few age-specific policies or person-centered practice guidelines are available to reduce sexual risk. In this commentary we explore the unique characteristics of emerging adulthood that contribute to greater sexual and reproductive health risks for women. Current evidence on sexual and reproductive health outcomes of women during emerging adulthood and limited practice guidelines are discussed. Recommendations for health care providers, especially nurses, for guiding personalized care for women in emerging adulthood are discussed.

The Effects of Trauma, Violence, and Stress on Sexual Health Outcomes Among Female Clinic Clients in a Small Northeastern U.S. Urban Center

Background: Threats to sexual health can emerge across one's life span and are influenced by individual and interpersonal experiences, as well as certain environmental exposures. Although previous research has recognized the importance of ecological frameworks to understand the complexity of health and behaviors in marginalized communities, there continues to be a dearth of research that truly utilizes this perspective to gain insight into the multifaceted factors that can concurrently influence threats to sexual health among women. Methods: A sample of 279 ethnoracially diverse women were recruited from a U.S. northeastern small urban center health clinic to participate in a parent study on trauma and immunity. A hierarchical block analysis was conducted to investigate associations between women's experiences of trauma, stress and violence (i.e., childhood trauma (CHT), intimate partner violence (IPV), neighborhood stressors), and sexual health outcomes and behaviors (i.e., lifetime sexually transmitted infection [STI] diagnosis, concurrent partnerships, and lifetime sex trading). Results: In the full hierarchical model, IPV and life stress trauma were associated with lifetime sex trading and partner concurrency. Also in the full model, sexual CHT was associated with lifetime STI acquisition and partner concurrency, while emotional CHT was associated with lifetime sex trading. Lastly, as neighborhood disorder increased, so did the number of lifetime sex trading partners. Conclusion: Sexual health assessments in clinical and community settings require a holistic, comprehensive, and meaningful approach to inform person-centered health promotion intervention. Prevention and treatment interventions require a focus on parents and families, and should assist adolescents and young adults to adopt therapies for healing from these experiences of trauma, violence, and stress. Interventions to enhance sexual health promotion must also include the following: advocacy for safe environments, social policy that addresses lifelong impacts of CHT, and fiscal policy that addresses economic vulnerability among women and threatens sexual health. Further recommendations are discussed.

Incarceration and Number of Sexual Partners After Incarceration Among Vulnerable US Women, 2007-2017

Objectives. To examine whether women's incarceration increases numbers of total and new sexual partners.Methods. US women with or at risk for HIV in a multicenter cohort study answered incarceration and sexual partner questions semiannually between 2007 and 2017. We used marginal structural models to compare total and new partners at visits not following incarceration with all visits following incarceration and visits immediately following incarceration. Covariates included demographics, HIV status, sex exchange, drug or alcohol use, and housing instability.Results. Of the 3180 participants, 155 were incarcerated. Women reported 2 partners, 3 or more partners, and new partners at 5.2%, 5.2%, and 9.3% of visits, respectively. Relative to visits not occurring after incarceration, odds ratios were 2.41 (95% confidence interval [CI] = 1.20, 4.85) for 2 partners, 2.03 (95% CI = 0.97, 4.26) for 3 or more partners, and 3.24 (95% CI = 1.69, 6.22) for new partners at visits immediately after incarceration. Odds ratios were similar for all visits following incarceration.Conclusions. Women had more total partners and new partners immediately and at all visits following incarceration after confounders and loss to follow-up had been taken into account.

HIV Pre-Exposure Prophylaxis and Women: Survey of the Knowledge, Attitudes, and Beliefs in an Urban Obstetrics/Gynecology Clinic

Uptake of HIV pre-exposure prophylaxis (PrEP) is low among women at risk for HIV acquisition. Of 468,000 women, whom the United States Centers for Disease Control and Prevention estimates to be eligible for PrEP, only 10,000 unique women have begun therapy through the third quarter of 2015. These data suggest insufficient HIV prevention efforts. This study, conducted at the site of an urban academic medical center with an emergency department HIV prevalence rate of 4%, assesses the knowledge, attitudes, and beliefs of women toward PrEP. A self-administered survey was conducted among women at a family planning obstetrics/gynecology clinic at Temple University Hospital (Philadelphia, PA). Participants assessed their HIV acquisition risk and answered eight questions regarding knowledge, attitudes, and beliefs toward PrEP. Three hundred eighty-nine surveys met inclusion criteria. Sixty-five percent of women were black, and 73% were between 18 and 33 years of age. The median self-perceived risk score was 0 (interquartile range = 2) using a Likert scale. Thirty-three percent of women believed that PrEP could work, and 27% knew that such a regimen existed. Concerns existed toward cost (44%) and side effects (39%). Fifty-seven percent of women surveyed stated that they would take a medication to prevent HIV, and 64% felt comfortable discussing the subject with her doctor. Our data demonstrate a lack of PrEP knowledge, although willingness for uptake among women at risk for HIV acquisition, and a need for directed education and outreach.

Effectively Addressing Human Immunodeficiency Virus Disparities Affecting US Black Women

Black women have disproportionately higher rates of human immunodeficiency virus (HIV) infection, and low percentages being linked to care and becoming virally suppressed, compared with women of other races/ethnicities. To date, few evidence-based HIV prevention and care interventions tailored for black women exist. We highlight three essential factors to consider in designing culturally and gender-appropriate studies to address HIV-related disparities affecting black women: (1) social determinants of HIV risk, (2) determinants of equity, and (3) perceptions of black women's sexuality. Synergy between a strong evidence base and developing strong partnerships could accelerate progress toward HIV-related health equity for black women.

A latent class analysis of alcohol and drug use immediately before or during sex among women

BACKGROUND

Alcohol and drug use by women is related to high-risk sexual practices and protective behaviors.

OBJECTIVES

To determine sexual risk and protective behaviors using information about women's drug use immediately before or during sex.

METHODS

Latent class analysis using PROC LCA in SAS software was used to determine classes of women using both past 30-day drug use and before or during sex. Participants were recruited from a community-based research site located in a low socio-economic area of Los Angeles County and completed the Risk Behavior Assessment, which elicits information on drug and sex risk behaviors.

RESULTS

The Risk Behavior Assessment and HIV and sexually transmitted infections testing was obtained on 812 women. Five distinct groups were identified by PROC LCA: An Abstinent group comprised of 26% of participants; an Alcohol and Marijuana group (16%); an Amphetamine group (11%); a No Sex-with-Alcohol group (37%); and a Poly Drug group (11%). Multinomial logistic regression revealed that sexual behaviors and condom use were different across the five groups: The Alcohol and Marijuana group had a higher odds of vaginal intercourse, while the No Sex-with-Alcohol group was most likely to use condoms for vaginal intercourse. The Poly Drug group had the highest risk for anal intercourse while the Amphetamine and Poly Drug groups had high proportions of women with injection-drug using and men-who-have-sex-with-men sexual partners.

CONCLUSION

Identifying women based on drug use immediately before or during sex can help providers understand prevention and risk-reduction practices and interventions for drug-using women.

Optimizing Delivery of HIV Preexposure Prophylaxis for Women in the United States

Preexposure prophylaxis (PrEP) is a highly effective HIV prevention method; however, it is underutilized among women who are at risk for acquisition of HIV. Women comprise one in five HIV diagnoses in the United States, and significant racial disparities in new HIV diagnoses persist. The rate of new HIV diagnoses among black and African American women in 2015 was 16 times greater than that of white women. These disparities highlight the importance of HIV prevention strategies for women, including the use of PrEP. PrEP is the first highly effective HIV prevention method available to women that is entirely within their control. However, because so few women who may benefit from PrEP are aware of it, few women's healthcare providers offer PrEP to their patients, PrEP has not yet achieved its potential to reduce HIV infections in women. This article describes individual and systemic barriers for women related to the uptake of PrEP services; explains how providers can identify women at risk for HIV; reviews how to provide PrEP to women; and outlines client-centered models for HIV prevention services. Better access to culturally acceptable and affordable medical and social services may offer support to women for consistent and ongoing use of PrEP. This discussion may be used to inform HIV prevention activities for women and guide interventions to decrease racial/ethnic disparities in rates of HIV infection among US women.

Exploring Factors Associated with Declining HIV Diagnoses Among African American Females

HIV diagnoses among females in the USA declined 40% during 2005-2014 with the largest decline (42%) among Black/African Americans. African American females remain disproportionately affected. We explored contributions of STD rates and sexual risk behaviors among African American females, HIV diagnoses among potential male partners, and sexual risk behaviors and viral suppression rates among HIV-positive potential male partners to declining rates of HIV diagnoses among African American females. Results suggest temporal trends in the factors that increase HIV infectiousness and transmissibility within sexual networks, i.e., decreases in rates of other sexually transmitted infections among African American females, decreases in HIV diagnoses among potential male partners, and increases in viral suppression among heterosexual and bisexual HIV-positive potential male partners in care, may explain the decline. Findings highlight a need for future research that provides context to the sexual risk behaviors and sexual network factors in order to continue progress.
