Sexually transmitted infections and risk behaviours in women who have sex with women

How LGBTQ+ Young Adults Navigate Personal Risk in App-Based Hookups: The Safety Spectrum Theory

Research on hooking up is rife with examinations of risky sexual health practices among LGBTQ+ young adults; yet, little has been written about the personal safety practices for this population. This omission is notable because safety practices can enhance the notable positive outcomes related to hooking up. Drawing on one-on-one interviews with 50 LGBTQ+ young adults (20 cismen, 20 ciswomen, two transmen, and eight others) in British Columbia, California, and Connecticut, we developed the safety spectrum theory, which used a spectral measurement to assess how LGBTQ+ young adults negotiate safety practices and implement safety rules. This spectrum was then applied to a three-step sequence of application (app)-based hookup rituals: online initiation, pre-meeting preparation, and in-person meetup. Results indicated that safety strategies may be dictated by situational factors, where individuals adapt to varying circumstances to be more in control of personal safety when hooking up. We further identified that participants move across the spectrum depending upon contextual factors, such as the gender of the potential hookup partner. This work suggests that LGBTQ+ young adults are mindful of their personal safety and deserve more credit than previously attributed in queer and sexual health research. From these findings, we provide evidence-based recommendations to make dating/hookup apps and public health campaigns more effective at mitigating hookup-related risks.

Syphilis seroprevalence and associated factors: A cross-sectional study in formal female sex workers in a province of Peru

Syphilis is a sexually transmitted infection (STI) considered a public health problem that affects vulnerable and at-risk populations, such as sex workers. We designed a retrospective cross-sectional study based on the review of health evaluation records of sex workers who attended consultations to obtain comprehensive health cards at a Health Center in the Province of San Vicente de Cañete in Peru during the year 2020. We obtained sociodemographic and employment information and the RPR (rapid plasma reagin) test results to diagnose syphilis. We evaluated 220 records of sex workers with a mean age of 27.9 ± 6.9 years and the initiation of sexual relations of 16.0 ± 1.6 years, while the accumulated time they had as sex workers was 2.9 ± 2.4 years. 85.9% of those evaluated reported being heterosexual. The prevalence of syphilis was 7.3% (CI95: 4.2%-11.5%). Being a homosexual sex worker was significantly associated with syphilis (OR: 19.6; 95% CI: 4.8-80.0) compared to heterosexuals. The prevalence of syphilis presented a value similar to that reported in other Latin American and national studies, and it is evident that it is a health problem among sex workers.

Sexually transmitted infections and associated risk factors among sexual minority women in China

There is a potential for transmission of sexually transmitted infections (STIs) within sexual minority women (SMW) in China. However, research specifically focused on STIs among SMW in China is severely limited. This study aims to evaluate the prevalence of STIs and identify associated risk factors among SMW in Beijing, China. This study comprised a baseline assessment followed by a follow-up evaluation. Consistent questionnaire interviews and STI tests were administered during both stages. Participants were recruited online in Beijing between 2020 and 2021 and factors associated with STIs were analyzed using logistic and Cox regression models. The baseline included 219 SMW, and 58.9% (129/219) of these individuals participated in the follow-up. During the baseline assessment, 4.1% (9/219) tested positive for chlamydia infection, while 5.0% (11/219) were HSV-2 seropositive. At the follow-up, the incidence of HSV-2 was 3.7 cases per 100 person-years. Notably, engaging in sexual activity with men and having an increased number of sexual partners were both identified as factors associated with a higher risk of STIs. The findings suggest that SMW in Beijing may face a significant risk of contracting STIs. As a preventive measure, there should be a concerted effort to promote STI testing within the SMW community.

Medical Counseling on Sexual Enrichment Aids: Women's Preferences and Medical Practitioner Expertise

OBJECTIVE

To investigate women's preferences and experiences regarding health counseling of safe sexual enrichment aid use and hygiene and current counseling behaviors of medical practitioners on this topic.

METHODS

This study used mixed methodology, leveraging quantitative data from a cross-sectional survey of 800 women and semi-structured qualitative interview data from 24 women across sexual practice groups. Additionally, we conducted a cross-sectional survey of 192 medical practitioners to understand current counseling behaviors and attitudes.

RESULTS

The majority of women (96.2%, 607/631) had never been counseled by a practitioner on safe sexual enrichment aid use and hygiene but would feel comfortable receiving counseling on the subject under certain circumstances. Overwhelmingly, women indicated the need for a nonjudgmental practitioner. Many cited the importance of having a female practitioner and preferred one within obstetrics and gynecology. Among medical practitioners, counseling on this topic was infrequent; 27.0% (52/192) stated that they counsel patients on safe sexual enrichment aid use and hygiene when discussing safe sex, and 21.4% (41/192) reported that this topic is included when counseling women after a sexually transmitted infection diagnosis. Only 7.4% (14/188) and 6.4% (12/188) had received training on this topic or were aware of any professional guidelines or recommendations, respectively.

CONCLUSION

Evidence-based guidelines should be developed that practitioners can use to counsel patients, ensuring that women are able to engage in sexual enrichment aid use safely.

Patterns of Sexual Practices, Sexually Transmitted Infections and Other Genital Infections in Women Who Have Sex with Women Only (WSWO), Women Who Have Sex with Men Only (WSMO) and Women Who Have Sex with Men and Women (WSMW): Findings from a Sexual Health Clinic in Melbourne, Australia, 2011-2019

Despite rises in sexually transmitted infection (STI) notifications among Australian women in the last decade, limited STI surveillance data exist specifically for women who have sex with women. This study aimed to compare differences in sexual practices and positivity for STIs and other genital infections among women who have sex with men only (WSMO), women who have sex with women only (WSWO), and women who have sex with men and women (WSMW), and whether these changed over time. In this retrospective repeated cross-sectional study, women attending the Melbourne Sexual Health Centre for the first time between 2011 and 2019 were categorized as "WSMW," "WSWO," or "WSMO" according to self-reported sexual practices in the previous 12 months. Demographic information, sexual practices, and positivity for STIs and other genital infections were compared between the three groups and over time. A total of 36,147 women (2618 WSMW, 534 WSWO, and 32,995 WSMO) were included. WSMW reported more sexual partners (median = 6; IQR = 4-10) than WSMO (median = 3; IQR = 2-5) and WSWO (median = 2; IQR = 1-4) (p < .001). A higher proportion of WSMW always used condoms with casual male partners compared to WSMO (20.4% vs 15.9%; p < .001). The proportion of women who always used condoms with casual male partners decreased over time in WSMO, (19.9% in 2011 to 15.2% in 2019, p_trend < .001) but not in WSMW. Bacterial vaginosis was more common in WSWO (14.8%) than in WSMW (11.8%) and WSMO (7.7%) (p < .001). Chlamydia was more common in WSMO (9.3%) than in WSMW (6.6%) and WSWO (1.2%) (p < .001). Syphilis was more common in WSMO (1.0%) than in WSMW (0.3%) and WSWO (0.0%) (p = .004). Over time, chlamydia positivity in WSWO increased (from 0.0% to 2.7%, p_trend = .014), and syphilis positivity in WSMW increased (from 0.0% to 0.7%, p_trend = .028); however, positivity of these STIs did not change in other groups. Sexual practices and positivity for STIs and other genital infections differed according to the sex of women's partners in the previous 12 months. Knowledge of these differences is important to account for future changes in STI trends that may occur in these subpopulations.

Sexual health behavior, health status, and knowledge among queer womxn and trans men in Kenya: An online cross-sectional study

Introduction

Little research has been conducted on the sexual health needs and risk behaviors of queer womxn and trans men, making it difficult to identify specific health needs and disparities. This is especially the case in the Global South, where their needs are poorly understood. This study presents findings on demographics, sources of information, sexual (risk) behaviors, and substance use in Kenyan queer womxn and trans men.

Methods

An online survey among 335 Kenyan queer womxn and trans men was used to collect data on sexual health, risk behavior, health information sources, and substance use. The participants needed to have had at least one self-identified female sexual partner.

Results

The sample presented young, highly-educated queer womxn and trans men. A high incidence of childhood sexual trauma found was found. Risk behaviors included sexual activities with partners of multiple genders, violence, and low use of barrier methods. One in three participants had been treated for an STD in the previous year. The incidences of smoking and drinking were high, and a quarter of participants indicated having taken drugs at least once a month or more. The internet was either the first or second most important source of sexual health information for 44.1% of the participants, followed by schools (30.9%).

Discussion and conclusion

Our findings indicate that queer womxn and trans men are at risk of negative sexual health outcomes due to a lack of appropriate information, risk behavior, substance use, and low uptake of sexual health services. Kenya’s Penal Code still criminalizes consensual same-sex activities and may play a role in perpetuating barriers that prohibit them from making healthier choices. Developing tailored programming and policies require local, national, and global stakeholders to engage with the inclusion of queer womxn and trans men’s sexual health needs within strategic planning and healthcare delivery.

Infertility and same-sex attraction in women

A polygyny hypothesis of female sexual fluidity proposes that women may have been evolutionarily selected to be sexually fluid, in order to have occasional sex with their cowives in polygynous marriage to reduce tension and conflict inherent in such marriage, while at the same time reproducing children with their husbands. Among others, the hypothesis predicts that women who are biologically (but not surgically) infertile would experience greater same-sex attraction. Biological infertility stems from natural, evolutionarily familiar causes such as menopause, whereas surgical infertility stems from artificial, evolutionarily novel causes such as tubal ligation or hysterectomy. Consistent with the prediction, the analyses of the National Survey of Family Growth data showed that biological infertility, but not surgical infertility, was significantly associated with same-sex self-identified labels, behavior and sexual attraction in women. Biological infertility nearly doubled the odds of women having engaged in same-sex behavior and the number of same-sex partners in the last 12 months and nearly tripled the number of same-sex partners in life. In sharp contrast, biological infertility was not associated (and surgical infertility was significantly negatively associated) with same-sex attraction in men.

Sexually Transmitted Infections Treatment Guidelines, 2021

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11–14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

Bacterial vaginosis: controversial issues

The purpose of the review. Consideration of the most controversial issues regarding the possibility of sexual transmission of BV-associated microorganisms (bacterias) in women and men. Basic provisions. Bacterial vaginosis (BV) is a common disease associated with an increased risk of contracting sexually transmitted infections (including human papillomavirus and human immunodeficiency virus) in women and their male sexual partners. BV is characterized by polymicrobial transformations caused by Gardnerella vaginalis, which is the main etiological microorganism of this disease. G. vaginalis has a proven ability to form microbial biofilms on the mucosal surface. As a rule, from 10 to 12 different G. vaginalis genotypes can simultaneously reside in one biofilm, which provides it with a longer lifespan and viability. It has been shown that microorganisms in the biofilm acquire properties that reduce sensitivity to standard etiotropic therapy even at high doses of antibiotics. It was found that the cause of BV is a polymicrobial gardnerella biofilm, all components of which are transferred as a whole (for example, with the help of key cells), including during sexual contact. In this regard, the article discusses the possibility of using a new term biofilm gardnerellosis, which more accurately reflects the essence of this problem. Microbial biofilms organized by G. vaginalis are found in a significant number of women with BV and their sexual partners.

Factors associated with sexually transmitted infection diagnosis in women who have sex with women, women who have sex with men and women who have sex with both

INTRODUCTION

Many US women report same sex behaviour, yet data on risk factors and STIs in women who have sex with women (WSW), women who have sex with both men and women (WSB) and how these compare to women who have sex with men only (WSM) remain limited. Here we compared self-identified WSW, WSB and WSM attending two STI clinics in Baltimore, Maryland.

METHODS

This was a retrospective analysis using a database of first clinic visits 2005-2016. WSW and WSB were compared with an age-matched random sample of WSM. Proportions were compared using the χ² test. Acute STI (aSTI) was defined as gonorrhoea (Neisseria gonorrhoeae, GC), chlamydia (Chlamydia trachomatis, CT), trichomonas (Trichomonas vaginalis, TV) or early syphilis. Logistic regression was used to assess aSTI predictors. CT testing was not uniformly done, so a sensitivity analysis removing CT from the aSTI definition was conducted.

RESULTS

Visits from 1095 WSW, 1678 WSB and 2773 WSM were analysed. WSB had equal or higher test positivity for all STIs except urogenital chlamydia, had more sexual partners, were more likely to engage in transactional sex and were more likely to report drug use and binge drinking than WSM (p≤0.01). WSW had lower test positivity for urogenital GC and CT than WSM or WSB, but comparable test positivity for TV, higher reported binge drinking and comparable reported substance use as WSM. Younger age and cocaine use predicted STI diagnosis only in WSM.

CONCLUSIONS

WSB in these clinics bear an equal or higher burden of most STIs, have more partners and report more substance use than WSM. WSW carry a lower, but still substantial burden of STIs, and many report substance use. Factors predicting STI diagnosis differ between WSW, WSB and WSM suggesting that tailored STI prevention and testing approaches are needed in these groups.

Southern African Lesbian and Bisexual Women Responses to Symptoms of Sexually Transmitted Infections

Sexually transmitted infection (STI) in lesbian and bisexual women is a relatively unexplored topic, particularly for women from low- and middle-income countries. Despite perceptions that women who have sex with women (WSW) are at negligible risk of contracting STI, existing research demonstrates that WSW do become infected with STI. Given the opposition between assumptions of invulnerability and the observed risks, we explored how WSW would respond to symptoms of STI (i.e., wait until symptoms passed, see a medical doctor, and inform sexual partners). We used data collected as part of a collaboration between academic researchers and community-based LGBTQ organizations in Botswana, Namibia, South Africa, and Zimbabwe. Chi-squared tests were used to test whether participants' responses to hypothetical STI symptoms varied in relation to several intrapersonal, interpersonal, and structural factors. Multivariable logistic regression (backward) was used to assess whether these variables were independently associated with women's responses. Most women would be proactive in response to potential STI symptoms and would see a medical doctor. However, most women would not inform their sexual partner of symptoms of STI. Findings demonstrate several intrapersonal, interpersonal, and structural factors that influence WSW's health agency, and show a clustering of high-risk factors among women who would not be proactive about their health. Our findings suggest the need for improved health and health care of WSW in Southern Africa.

[Literature review on studies of women who have sex with women]

Women who have sex with other women are a group that has been mostly invisible from public health policies. This category includes the group of lesbians, bisexual women, heterosexual behaviour, and homosexual practices, who have sexual relations with transsexual and transgender (trans) women and trans men who have sex with women. In the absence of a Spanish literature review of a study that addresses women who have sex with other women, a narrative bibliographic review was done using the PubMed/MEDLINE, Scopus, Dialnet, and Taylor and Francis databases. From a universe of 679 articles and after applying the inclusion criteria, 40 documents were analysed, from 1998 to 2019. Three meta-categories were identified (sexual education, the incidence of certain sexually transmitted infections, and aspects related to sexual practices), concerning prevention and risky behaviours. Women who have sex with other women are a particularly vulnerable group when it comes to sexually transmitted infections. These may include bacterial vaginitis, human papillomavirus and acquired immunodeficiency virus. Likewise, there is a lack of specific training and information in health and education professionals, as well as in women who have sex with other women.

Examination of multilevel domains of minority stress: Implications for drug use and mental and physical health among Latina women who have sex with women and men

There has recently been growing attention and concern in the U.S. on the detrimental drug use and related health conditions impacting diverse sexual minority populations. While some evidence indicates that bisexual women are at increased risk of substance use, little attention has been given to disadvantaged and racial/ethnic minority bisexual women, who are particularly vulnerable to a complexity of stressors and risk. Using data from a 15-year longitudinal study in San Antonio, Texas, the current study examines drug use, incarceration histories, stressful life events, and infections among 206 young adult Mexican-American women who report engaging in sex with both men and women (WSWM) (n = 61) and those indicating having exclusively male sex partners (WSM) (n = 145). A bivariate analysis finds that WSWM experienced more frequent (p = 0.001) and longer total time incarcerated (p = 0.001), as well as exposure to more stressful life events (p = 0.003). WSWM also have higher rates of past 30 day injection drug use (p = 0.026) and related Hepatitis C Virus (HCV) infection (p = 0.001), as well as greater symptomatology associated with depression (p = 0.014), PTSD (p = 0.005), and suicidal ideation (p = 0.036). Findings indicate a significantly elevated risk profile for socio-economically marginalized WSWM. This knowledge is timely and central to policy discourse to develop interventions and health campaigns aimed at reducing and/or preventing further health disparities among this highly susceptible population of minority women.

Sexual Orientation Differences in Pregnancy and Abortion Across the Lifecourse

OBJECTIVES

We examined sexual orientation-related differences in various pregnancy outcomes (e.g., teen pregnancy, abortion) across the lifespan.

METHODS

We collected data from 124,710 participants in three U.S. longitudinal cohort studies, the Nurses' Health Study 2 and 3 and Growing Up Today Study 1, followed from 1989 to 2017. Multivariate regression was used to calculate differences of each outcome-ever had pregnancy, teen pregnancy, ever had abortion, and age at first birth-by sexual orientation groups (e.g., heterosexual, mostly heterosexual, bisexual, lesbian), adjusting for potential confounders of age and race/ethnicity.

RESULTS

All sexual minority groups-except lesbians-were generally more likely than heterosexual peers to have a pregnancy, a teen pregnancy, and an abortion. For example, Growing Up Today Study 1 bisexual participants were three times as likely as heterosexuals to have had an abortion (risk ratio, 3.21; 95% confident interval, 1.94-5.34). Lesbian women in all of the cohorts were approximately half as likely to have a pregnancy compared with heterosexual women. Few sexual orientation group differences were detected in age at first birth.

CONCLUSIONS

The increased risk of unintended pregnancy among sexual minority women likely reflects structural barriers to sexual and reproductive health services. It is critical that sex education programs become inclusive of sexual minority individuals and medical education train health care providers to care for this population. Health care providers should not make harmful heteronormative assumptions about pregnant patients and providers must learn to take sexual histories as well as offer contraceptive counseling to all patients who want to prevent a pregnancy regardless of sexual orientation.

Adolescent Sexual Health: Identity, Risk, and Screening for Sexually Transmitted Infections

Development of SOGIE (sexual orientation and gender identity and expression) is not unique to minority populations, as all adolescents grapple with their sexuality and identity. Health care providers straddle the unique positions of authority figure and advocate and can help these young people establish behaviors that will allow them to flourish as adults. This article discusses the appropriate language to use while conducting a sexual history, summarizes the epidemiologic data on sexually transmitted infections, and reviews the screening and reporting guidelines set forth by the United States Preventive Services Task Force and the Centers for Disease Control and Prevention.

Interest, Personality, and Sexual Traits That Distinguish Heterosexual, Bisexual, and Homosexual Individuals: Are There Two Dimensions That Underlie Variations in Sexual Orientation?

A diverse U.S. sample comprising 1437 men and 1474 women was assessed on sexual orientation, masculinity-femininity of occupational preferences (MF-Occ), self-ascribed masculinity-femininity (Self-MF), Big Five personality traits, sex drive, and sociosexuality (positive attitudes toward uncommitted sex). Discriminant analyses explored which traits best distinguished self-identified heterosexual, bisexual, and homosexual individuals within each sex. These analyses correctly classified the sexual orientation of 55% of men and 60% of women, which was substantially better than a chance rate (33%) of assigning participants to one of three groups. For men, MF-Occ and Self-MF distinguished heterosexual, bisexual, and gay men, with heterosexual men most gender typical, gay men most gender atypical, and bisexual men intermediate. Independently, higher sex drive, sociosexuality, and neuroticism and lower conscientiousness distinguished bisexual men from other groups. For women, gender-related interests and Self-MF distinguished lesbians from other groups, with lesbians most gender atypical. Independently, higher sociosexuality, sex drive, and Self-MF distinguished non-heterosexual from heterosexual women. These findings suggest that variations in self-reported sexual orientation may be conceptualized in terms of two broad underlying individual difference dimensions, which differ somewhat for men and women: one linked to gender typicality versus gender atypicality and the other linked to sex drive, sociosexuality, and various personality traits.

The discursive construction of low-risk to sexually transmitted diseases between women who are sexually active with women

This paper uses a discursive analytical method to explore dominant discourses concerning the sexual health of women who have sex with women. In-depth interviews were conducted with a cross-cultural sample of women from England and Brazil. Sex between women was discursively constructed as 'safe', and women who have sex with women were seen as being at low to negligible risk of contracting/transmitting sexually transmitted infections. Analysis identified two discourses underlying these constructions: a binaries discourse which focused on dichotomies of gender, sexuality and risk; and a sexual double-standard discourse, which focused on the positioning of sex between women as safe and the use of barrier methods of protection as indicative of not engaging in or fully enjoying the sexual act.

Patient-Provider Sexually Transmitted Infection Prevention Communication among Young Adult Sexual Minority Cisgender Women and Nonbinary Assigned Female at Birth Individuals

BACKGROUND

Health care providers are an important source of sexually transmitted infection (STI) prevention information for young adult sexual minority women (SMW). However, very few studies have described patient-provider STI communication in this understudied and underserved population. We explore sexual minority women's experiences communicating with health care providers about sexual health, with particular attention to STI prevention, to inform programs and practices that address their unique needs and concerns.

METHODS

We conducted 29 in-depth interviews with sexual minority cisgender women and nonbinary assigned female at birth (AFAB) individuals aged 18-36 years. The sample included White (55%), Asian (31%), Black (17.2%), and Latina (3.4%) participants. We used thematic analysis with deductive and inductive coding to identify themes related to patient-provider STI prevention communication.

RESULTS

Heteronormative health care provider assumptions inhibited participants' willingness to disclose their sexual orientation and discuss sexual health issues with providers. Most sexual health conversations focused on pregnancy and contraception, which many felt was irrelevant to them, and limited STI prevention recommendations to condom use. Participants reported that some providers lacked medical knowledge on AFAB-to-AFAB STI transmission and were not able to provide relevant STI prevention information. Providers' bias related to gender identity and race/ethnicity furthered some participants' mistrust generated from providers' heteronormative assumptions.

CONCLUSIONS

Our study describes several barriers that AFAB sexual minorities felt inhibited their patient-provider sexual health communication. Interventions are needed to improve patient-provider STI prevention conversations with AFAB sexual minorities so they can access the sexual health information they need to effectively protect themselves from STIs.

A Life History Approach to the Female Sexual Orientation Spectrum: Evolution, Development, Causal Mechanisms, and Health

Women's capacity for sexual fluidity is at least as interesting a phenomenon from the point of view of evolutionary biology and behavioral endocrinology as exclusively homosexual orientation. Evolutionary hypotheses for female nonheterosexuality have failed to fully account for the existence of these different categories of nonheterosexual women, while also overlooking broader data on the causal mechanisms, physiology, ontogeny, and phylogeny of female nonheterosexuality. We review the evolutionary-developmental origins of various phenotypes in the female sexual orientation spectrum using the synergistic approach of Tinbergen's four questions. We also present femme-specific and butch-specific hypotheses at proximate and ultimate levels of analysis. This review article indicates that various nonheterosexual female phenotypes emerge from and contribute to hormonally mediated fast life history strategies. Life history theory provides a biobehavioral explanatory framework for nonheterosexual women's masculinized body morphology, psychological dispositions, and their elevated likelihood of experiencing violence, substance use, obesity, teenage pregnancy, and lower general health. This pattern of life outcomes can create a feedback loop of environmental unpredictability and harshness which destabilizes intrauterine hormonal conditions in mothers, leading to a greater likelihood of fast life history strategies, global health problems, and nonheterosexual preferences in female offspring. We further explore the potential of female nonheterosexuality to function as an alloparental buffer that enables masculinizing alleles to execute their characteristic fast life history strategies as they appear in the female and the male phenotype. Synthesizing life history theory with the female sexual orientation spectrum enriches existing scientific knowledge on the evolutionary-developmental mechanisms of human sex differences.

Sexual Health Risk Behavior Disparities Among Male and Female Adolescents Using Identity and Behavior Indicators of Sexual Orientation

Sexual minority adolescent sexual risk behavior studies often overlook young women, do not consider behavior- and identity-based sexual orientation indicators in combination, and focus mainly on condomless sex. We examined multiple risk behaviors in a large sample of adolescent young men and women using combined behavior- and identity-based indices. The 2015 Dane County Youth Assessment data included 4734 students in 22 high schools who had ever voluntarily engaged in sexual contact (51.7% male; 76.0% White, non-Hispanic). Items assessed having sex with unfamiliar partners, sex while using substances, using protection, and STI testing. Logistic regressions tested for disparities based on combined identity- and behavior-based sexual orientation indicators. For both young men and women, youth who reported heterosexual or questioning identities-but who had sex with same-sex partners-were at consistently greater risk than heterosexual youth with only different-sex partners. Also, for both young men and women, bisexuals with partners of both sexes more consistently reported higher risk than heterosexual youth than did bisexuals with only different-sex partners. Risk behavior for gay young men who had sex only with men mirrored those in extant literature. Risk levels differed for specific groups of sexual minority young women, thus deserving further attention. Findings underscore the need for sexual health research to consider sexual orientation in a more multidimensional manner.

[Vulnerability to sexually transmitted infections of women who have sex with women]

The scope of this study was to assess the degree of vulnerability to sexually transmitted infections of women who have sex with women. It involved a cross-sectional study of 150 women between 2015 and 2017. A structured questionnaire was applied, and a gynecological examination was performed to diagnose Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and papillomavirus. Blood tests were conducted to detect HIV, hepatitis B and syphilis. The outcome variable was sexual infection and the independent variables comprised the vulnerability level in the individual, social and programmatic dimensions. Data analyses were performed through logistic regression. The results showed a high prevalence of infections (47.3%) and only variables of individual vulnerability were associated with the outcome. The incidence of infection was four times higher among women who had had prior infections. The fact of never having had a blood test tripled the chance of having sexually transmitted infections. The fact of also having sexual intercourse with men in the previous 12-month-period increased the risk of the outcome by a factor of approximately nine. The conclusion drawn is that these women are vulnerable to sexually transmitted infections due to their individual vulnerability.

Factors Associated with Sexual Risks and Risk of STIs, HIV and Other Blood-Borne Viruses Among Women Using Heroin and Other Drugs: A Systematic Literature Review

This systematic literature review identified factors associated with sexual risks related to sexually transmitted infections (STI), HIV and other blood-borne viruses (BBV) among women using heroin and other drugs. The search strategy included five databases (PubMed, EMBASE, PsycNET, Web of Science, Scopus), and PsycEXTRA for grey literature. Out of the 12,135 publications screened, 30 peer-reviewed articles were included. Most publications were cross-sectional (n = 25), quantitative (n = 23) and included 11,305 women. Factors identified were: (1) socio-demographics; (2) gender roles and violence against women; (3) substance use; (4) transactional sex; (5) partner characteristics, partner's drug use, and context of sex; (6) preferences, negotiation and availability of condoms; (7) HIV status and STIs; (8) number of sexual partners; (9) love and trust; (10) reproductive health and motherhood; and (11) risk awareness and perception of control. Overall, this review highlights important implications for future research and practice, and provides evidence for developing STI/BBV preventive strategies.

Impact of social factors and sexual behaviors on the knowledge of sexually transmitted infections among women who have sex with women/women who have sex with women and men

Although heterosexual individuals' knowledge of sexually transmitted infections (STIs) has been examined, no studies have been conducted in Poland of the STI knowledge in women who have sex with women (WSW) and women who have sex with women and men (WSWM). We enrolled a group of 146 WSW and 113 WSWM and asked them to complete a study questionnaire that contained items about socioeconomic factors, sexual behaviors, and STI knowledge. The level of STI knowledge among the studied WSW was insufficient. The frequency of correct answers was higher in WSWM. A multivariate regression model revealed that only the higher importance of sex to the respondents ( F(1) = 4.31, p = 0.04) and a higher number of same-sex sexual partners within the last 12 months ( F(1) = 14.86, p = 0.0001) influenced the level of STI knowledge. The results of the study allowed us to conclude that WSW have insufficient STI knowledge, whereas WSWM have better knowledge, and this is influenced by awareness that STI risk is not associated with the partner's gender, age, importance of sex, sexual behaviors, and openness to discussing STIs with a sexual partner.

Sexual Orientation and Exposure to Violence Among U.S. Patients Undergoing Abortion

OBJECTIVE

To assess the characteristics of patients undergoing abortion in the United States according to sexual orientation and exposure to sexual and physical violence.

METHODS

Data for this observational study come from the Guttmacher Institute's 2014 Abortion Patient Survey, which obtained information from 8,380 individuals obtaining abortions at nonhospital facilities in the United States; 7,656 of those (91%) provided information on sexual orientation identity. We used simple logistic regression to assess differences between heterosexuals and three sexual minority groups-bisexual, lesbian, and something else-according to demographic characteristics and exposure to sexual and physical violence. Multivariate logistic regression was used to assess associations between sexual orientation and exposure to violence.

RESULTS

Among patients undergoing abortion in 2014, 4.1% identified as bisexual (n=316), 1.1% as something else (n=81), and 0.4% as lesbian (n=28); 94.4% identified as heterosexual (n=7,231). Similar proportions of lesbian and heterosexual respondents reported a prior birth (53.6% and 58.2%, P=.62), whereas respondents who identified as something else were more likely to report having had a prior abortion (58.0% vs 43.9%, P=.01). Exposure to sexual violence was substantially and significantly higher among all three sexual minority groups compared with heterosexuals, and lesbian and bisexual respondents were also more likely than their heterosexual peers to report exposure to physical violence by the man involved in the pregnancy (33.3% and 8.7% vs 3.6%, P<.001).

CONCLUSION

No patient should be presumed to be heterosexual. Understanding the disproportionate role of sexual violence in unintended pregnancies among sexual minorities may aid in the design of interventions and clinical guidelines that address the needs of sexual minority patients.

Sexual Orientation Differences in Health and Wellbeing Among Women Living with HIV in Canada: Findings from a National Cohort Study

Sexual orientation differences in health and wellbeing among women living with HIV (WLH) are underexplored. Limited research available, however, suggests that sexual minority WLH may experience barriers to HIV care. Cross-sectional baseline data was analyzed from a Canadian cohort study with WLH (sexual minority women [SMW]: n = 180; heterosexual women: n = 1240). SMW (median age 38 years, IQR 13) included bisexual (58.9%), lesbian (17.8%) and other sexualities (23.3%). In multivariable analyses adjusting for age, poverty, education, and ethnicity, SMW identity was associated with increased odds of: clinical (80% vs. 100% antiretroviral adherence), intrapersonal (previous/current injection drug use [IDU] vs. no IDU history, depression, lower resilience), interpersonal (childhood abuse, sex work, adulthood abuse), and structural (HIV support services barriers, unstable housing, racial discrimination, gender discrimination) factors in comparison with heterosexual identity. Sexual minority WLH experience social and health disparities relative to heterosexual WLH, highlighting the need for interventions to promote health equity.

“La solución es la tijera”: Programa de Salud Sexual para Mujeres Lesbianas y Bisexuales

RESUMEN La inclusión de las mujeres lesbianas y bisexuales en las agendas de promoción de la salud sexual es escasa. Sin embargo, los riesgos en sus prácticas sexuales han sido reconocidos científicamente. Este artículo presenta los resultados principales del programa de intervención “La solución es la tijera” dirigido a mujeres lesbianas y bisexuales jóvenes de Cali, Colombia. Participaron 23 mujeres entre los 18 y los 25 años de edad (X= 21.7; DS=1.78). La evaluación se realizó de manera pre- post a través de una metodología mixta. Se encontró un cambio significativo en los niveles de conocimientos y las actitudes frente al VIH. Asimismo, se reportó el fortalecimiento de la identidad, el empoderamiento en su sexualidad y los conocimientos sobre derechos sexuales y reproductivos.

Family Planning for Sexual Minority Women

The family planning needs of sexual minority women (SMW) are an understudied but growing area of research. SMW have family planning needs, both similar to and distinct from their exclusively heterosexual peers. Specifically, SMW experience unintended pregnancies at higher rates than their exclusively heterosexual peers, but factors that increase this risk are not well understood. Contraception use is not uncommon among SMW, but lesbian women are less likely to use contraception than bisexual or exclusively heterosexual women. High rates of unintended pregnancy suggest contraception is underused among SMW. Contraception counseling guidelines specific to SMW do not yet exist, but greater adoption of current best practices is likely to meet the needs of SMW. SMW may have unique needs for their planned pregnancies as well, for which obstetrics and gynecology (Ob/Gyn) providers should provide care and referrals. In general, understandings of the distinct family planning needs for SMW are limited and further research is needed, with particular attention to issues of overlapping health disparities related to status as a SMW and other factors such as race/ethnicity that may add additional layers of stigma and discrimination. Clinical resources are needed to help Ob/Gyns make their practice more welcoming to the needs of SMW.

Considerations for the design of Human Immunodeficiency Virus (HIV) prevention programs for lesbian and bisexual women

Several strategies and guidelines for HIV prevention in different population groups have been established throughout the epidemic. However, there is an urgent need to include lesbian and bisexual women (LB women) in prevention programs and address their particular health care needs. This paper discusses key aspects that must be considered in the design of HIV prevention programs oriented toward this specific population. Due to the lack of research assessing prevention strategies for LB women, these reflections emerged by reviewing literature in similar groups and by the direct work of the authors within this group. Their inclusion in the HIV prevention agenda is essential to safeguard their right to health care in terms of receiving accurate information about sexuality and health, participating in health care programs and being treated equally and without any discrimination.

Current Treatment of Bacterial Vaginosis-Limitations and Need for Innovation

Practitioners and patients alike widely recognize the limitations of current therapeutic approaches to the treatment of bacterial vaginosis (BV). Options remain extremely limited, and our inability to prevent the frequently, often relentless symptomatic recurrences of BV and to reduce serious sequelae such as preterm delivery, remains an acknowledged but unresolved shortcoming. Our incomplete understanding of the pathophysiology of this unique form of vaginal dysbiosis has been a significant impediment to developing optimal treatment and prevention approaches. New drugs have not been forthcoming and are not likely to be available in the immediate future; hence, reliance on the optimal use of available agents has become essential as improvised often unproven regimens are implemented. In this review, we will explore the limitations of currently recommended therapies, with a particular focus on the contribution of reinfection and pathogen persistence to BV recurrence, and the development of interventions that target these mechanisms. Ultimately, to achieve sustained cure and effectiveness against BV-associated sequelae, it is possible that we will need approaches that combine antimicrobials with biofilm-disrupting agents and partner treatments in those at risk of reinfection.

Correlates of Human Papillomavirus Infection Among a National Sample of Sexual Minority Women

BACKGROUND

Many sexual minority women are infected with human papillomavirus (HPV), yet little is known about correlates of HPV infection among this population.

MATERIALS AND METHODS

We analyzed data from a national sample of sexual minority women (i.e., women who either reported a history of female sexual partners or identified as nonheterosexual) aged 20-59 from the 2003 to 2012 National Health and Nutrition Examination Survey (n = 830). Weighted logistic regression identified correlates of infection with any HPV type and infection with a high-risk HPV type.

RESULTS

About 53% of women were infected with any HPV type, and about 37% were infected with a high-risk HPV type. Women who reported five or more sexual partners during their lifetime (adjusted odds ratio [aOR] = 5.07, 95% confidence interval [CI]: 2.26-11.42) were more likely to be infected with a high-risk HPV type. Compared to women aged 20-29, women aged 40-49 (aOR = 0.51, 95% CI: 0.32-0.81) or 50-59 (aOR = 0.27, 95% CI: 0.14-0.53) were less likely to be infected with a high-risk HPV type, as were women who were married or living with a partner (aOR = 0.62, 95% CI: 0.44-0.89). Mostly similar correlates were identified for infection with any HPV type, although infection with any HPV type was also less common among women who identified as lesbian compared to those who identified as heterosexual (aOR = 0.38, 95% CI: 0.21-0.68).

CONCLUSIONS

Demographic and health-related characteristics were associated with HPV infection outcomes. Findings can inform HPV prevention efforts for sexual minority women by providing information about risk factors and subgroups at particular risk for infection.

Adolescent Sexuality: Updates to the Sexually Transmitted Infection Guidelines

Adolescents are at high risk for acquisition and transmission of sexually transmitted infections (STI) secondary to both cognitive and biological susceptibility. The prevention, diagnosis, and treatment of STIs are a critical part of adolescent health care. This article discusses the most common bacterial, parasitic, and viral STIs encountered in this age group with an emphasis on new guidelines for screening and management.

Condomless Sex Among Homeless Youth: The Role of Multidimensional Social Norms and Gender

Most studies of condomless sex among homeless youth have focused on peer norms, while excluding other potentially pertinent influences. This study explored how different types of relationships contributed to norms about condomless sex and whether such norms were associated with engagement in condomless sex among homeless youth. Additionally, because recent work has noted gender differences in social networks of male and female homeless youth, gender differences in social network norms of condomless sex were also assessed. Egocentric network data were collected from homeless youth accessing services at two drop-in centers in Los Angeles, CA (N = 976). Multivariate analyses (non-stratified and stratified by gender) assessed associations between descriptive, injunctive, and communicative norms and participants' engagement in condomless sex. Multivariate analyses indicated that perception of peer condom use and communication with sexual partners were significantly associated with not engaging in condomless sex. These relationships, however, varied by gender. Implications for interventions are discussed.

Lesbian and bisexual women's likelihood of becoming pregnant: a systematic review and meta-analysis

BACKGROUND

Few data exist regarding pregnancy in lesbian and bisexual (LB) women.

OBJECTIVES

To determine the likelihood of LB women becoming pregnant, naturally or assisted, in comparison with heterosexual women SEARCH STRATEGY: Systematic review of papers published 1 January 2000 to 23 June 2015.

SELECTION CRITERIA

Studies contained details of pregnancy rates among LB women compared with heterosexual women. No restriction on study design.

DATA COLLECTION AND ANALYSIS

Inclusion decisions, data extraction and quality assessment were conducted in duplicate. Meta-analyses were carried out, with subgroups as appropriate.

MAIN RESULTS

Of 6859 papers identified, 104 full-text articles were requested, 30 papers (28 studies) were included. The odds ratio (OR) of ever being pregnant was 0.19 (95% CI 0.18-0.21) in lesbian women and 1.22 (95% CI 1.15-1.29) in bisexual women compared with heterosexual women. In the general population, the odds ratio for pregnancy was nine-fold lower among lesbian women and over two-fold lower among bisexual women (0.12 [95% CI 0.12-0.13] and 0.50 [95% CI 0.45-0.55], respectively). Odds ratios for pregnancy were higher for both LB adolescents (1.37 [95% CI 1.18-1.59] and 1.98 [95% CI 1.85, 2.13], respectively). There were inconsistent results regarding abortion rates. Lower rates of previous pregnancies were found in lesbian women undergoing artificial insemination (OR 0.17 [95% CI 0.11-0.26]) but there were higher assisted reproduction success rates compared with heterosexual women (OR 1.56 [95% CI 1.24-1.96]).

CONCLUSIONS

Heterosexuality must not be assumed in adolescents, as LB adolescents are at greater risk of unwanted pregnancies and terminations. Clinicians should provide appropriate information to all women, without assumptions about LB patients' desire for, or rejection of, fertility and childbearing.

TWEETABLE ABSTRACT

Review of likelihood of LB women becoming pregnant: LB teenagers at greater risk of unwanted pregnancies.

Infectious Disease Issues in Underserved Populations

Infectious disease has a major impact on the health outcomes of underserved populations and is reported at significantly higher rates among these populations compared with the general population. Overcoming barriers and obstacles to health care access is key to addressing the disparity regarding the prevalence of infectious disease. Enhancing cultural competency and educating practitioners about underserved populations' basic health needs; optimizing health insurance for the underserved; increasing community resources; and improving access to comprehensive, continuous, compassionate, and coordinated health care are strategies for diminishing the burden of infectious disease in underserved populations.

Minority Stress and Safer Sex Practices Among Sexual Minority Women in Toronto, Canada: Results from a Cross-Sectional Internet-Based Survey

PURPOSE

Sexual stigma is a chronic stressor that enhances vulnerability to mental health disparities among lesbian, gay, bisexual, and queer people. Sexual stigma has also been associated with reduced uptake of safer sex practices, such as condom use, among gay and bisexual men. Scant research has examined the relationship between sexual stigma and safer sex practices among sexual minority women (SMW), including lesbian, bisexual, and queer women.

METHODS

We explored associations between sexual stigma and safer sex practices among SMW. We also tested the interaction between sexual stigma, social support, and resilient coping in this relationship. A cross-sectional internet-based survey was administered to SMW in Toronto, Canada.

RESULTS

Among 388 participants with complete measurement data, simple linear regression indicated both perceived and enacted sexual stigma were positively associated with uptake of safer sex practices. In multivariable analyses, significant interactions were found between perceived sexual stigma and resilient coping, and between enacted sexual stigma and social support. At low levels of resilient coping, higher levels of perceived sexual stigma were associated with fewer safer sex practices, while at high levels of resilient coping the relationship was reversed. At low levels of social support, higher levels of enacted sexual stigma were associated with fewer safer sex practices, while at high levels of social support the relationship was reversed.

CONCLUSIONS

These findings document complex relationships between sexual stigma dimensions, coping, social support, and safer sex practices. Understanding the role these variables play in uptake of safer sex practices can inform sexual health interventions tailored for SMW.

Bisexual Invisibility and the Sexual Health Needs of Adolescent Girls

PURPOSE

The purpose of this study was to analyze bisexual female youth perspectives on their experiences accessing sexual health information and services provided by a doctor, nurse, or counselor. Specifically, we sought to: (1) understand how youth perceptions of providers' attitudes and behaviors affect their seeking and obtaining sexual health information and services; (2) examine how social stigmas within the family context might be associated with barriers to sexual health information and services; and (3) assess school-based sources of sexual health information.

METHOD

We utilized a mixed-method study design. Data from bisexual female youth were collected through an online questionnaire and asynchronous online focus groups addressing lesbian, gay, bisexual, and transgender health and HIV prevention. Data were analyzed with descriptive statistics and thematic analysis.

RESULTS

Barriers to sexual healthcare included judgmental attitudes and assumptions of patient heterosexuality among healthcare providers, and missed opportunities for HIV and sexually transmitted infections (STI) testing. Bisexual stigma within families was associated with restricted youth openness with providers, suggesting fear of disclosure to parent or guardian. School-based sexual health education was limited by a restrictive focus on abstinence and condoms and the exclusion of STI risk information relevant to sex between women.

CONCLUSION

We recommend that practitioners integrate nonjudgmental questions regarding bisexuality into standard contraceptive and sexual health practices involving female youth, including discussion of HIV and STI risk reduction methods. Further support for bisexual health among adolescent girls can come through addressing stigmas of female bisexuality, increasing sensitivity to privacy while engaging parents, and expanding the reach of school-based sexual health education.

Anxiety and Depressive Symptoms Among People Living with HIV and Childhood Sexual Abuse: The Role of Shame and Posttraumatic Growth

There is a critical need to examine protective and risk factors of anxiety and depressive symptoms among people living with HIV in order to improve quality of life. Structural equation modeling was used to examine the associations between HIV-related shame, sexual abuse-related shame, posttraumatic growth, and anxiety and depressive symptoms among a cohort of 225 heterosexual women and men who have sex with men (MSM) living with HIV who have experienced childhood sexual abuse (CSA). Higher sexual abuse-related shame was related to more anxiety and depressive symptoms for heterosexual women. Higher posttraumatic growth predicted less anxiety symptoms for only heterosexual women. Higher posttraumatic growth predicted less depressive symptoms for heterosexual women and MSM, but the magnitude of this effect was stronger for heterosexual women than MSM. Psychosocial interventions may need to be tailored to meet the specific needs of heterosexual women and MSM living with HIV and CSA.

A National Study of Lesbian, Gay, Bisexual (LGB), and Non-LGB Youth Sexual Behavior Online and In-Person

Online and in-person sexual behaviors of cisgender lesbian, gay, queer, bisexual, heterosexual, questioning, unsure, and youth of other sexual identities were examined using data from the Teen Health and Technology study. Data were collected online between August 2010 and January 2011 from 5,078 youth 13-18 years old. Results suggested that, depending on sexual identity, between 4-35 % of youth had sexual conversations and 2-24 % shared sexual photos with someone online in the past year. Among the 22 % of youth who had oral, vaginal, and/or anal sex, between 5-30 % met one of their two most recent sexual partners online. Inconsistent condom use was associated with increased odds of meeting one's most recent partner online for heterosexual adolescent men. For gay and queer adolescent men, having an older partner, a partner with a lifetime history of sexually transmitted infections (STI), and concurrent sex partners were each significantly associated with increased odds of having met one's most recent sex partner online. None of the examined characteristics significantly predicted meeting one's most recent sexual partner online versus in-person for heterosexual; bisexual; or gay, lesbian, and queer women. The Internet is not replacing in-person exploration and expression of one's sexuality and meeting sexual partners online appears to be uncommon in adolescence across sexual identities. Healthy sexuality programming that acknowledges some youth are meeting partners online is warranted, but this should not be a main focal point. Instead, inclusive STI prevention programming that provides skills to reduce risk when engaging in all types of sex is critical.

HIV Risk Among Men Who Have Sex With Men, Women Who Have Sex With Women, Lesbian, Gay, Bisexual and Transgender Populations in South Africa: A Mini-Review

BACKGROUND

The HIV epidemic in South Africa is characterized mainly by heterosexual transmission. Recently, the importance of targeting key populations and marginalized groups, including men who have sex with men (MSM) and transgender people, has been added to the national agenda.

OBJECTIVES

This mini-review explores the current state of empirical research on HIV risk and MSM, women who have sex with women (WSW), lesbian, gay, bisexual and transgender (LGBT) populations in South Africa in order to assess the current state of research and identify gaps in the literature.

METHOD

Peer-reviewed empirical social and behavioral articles on HIV prevalence and risk focusing on MSM, WSW, and LGBT populations published since 2006 were included in this mini-review.

RESULTS

In total 35 articles were included: 30 on MSM, gay, and/or bisexual male-identified populations, three on WSW, lesbian, and/or bisexual female-identified populations, two on LGB youth, and none on transgender populations.

CONCLUSION

Despite South Africa being the country with the largest number of people living with HIV in the world, there is a limited amount of research in South Africa on HIV and non-normative gender identities and sexualities, especially WSW, lesbian, and/or bisexual female-identified populations, transgender populations, and LGB youth. Research with MSM, WSW, and LGBT populations should be prioritized in South Africa in order to appropriately inform HIV prevention strategies that meet the specific needs of these marginalized groups.

Women's Management of Recurrent Bacterial Vaginosis and Experiences of Clinical Care: A Qualitative Study

BACKGROUND

Few data are available on how women manage recurring bacterial vaginosis (BV) and their experiences of the clinical care of this condition. This study aimed to explore women's recurrent BV management approaches and clinical care experiences, with a view to informing and improving the clinical management of BV.

METHODS

A descriptive, social constructionist approach was chosen as the framework for the study. Thirty-five women of varying sexual orientation who had experienced recurrent BV in the past 5 years took part in semi-structured interviews.

RESULTS

The majority of women reported frustration and dissatisfaction with current treatment regimens and low levels of satisfaction with the clinical management of BV. Overall, women disliked taking antibiotics regularly, commonly experienced adverse side effects from treatment and felt frustrated at having symptoms recur quite quickly after treatment. Issues in clinical care included inconsistency in advice, misdiagnosis and inappropriate diagnostic approaches and insensitive or dismissive attitudes. Women were more inclined to report positive clinical experiences with sexual health physicians than primary care providers. Women's frustrations led most to try their own self-help remedies and lifestyle modifications in an attempt to treat symptoms and prevent recurrences, including well-known risk practices such as douching.

CONCLUSION

In the face of considerable uncertainty about the cause of BV, high rates of recurrence, unacceptable treatment options and often insensitive and inconsistent clinical management, women are trying their own self-help remedies and lifestyle modifications to prevent recurrences, often with little effect. Clinical management of BV could be improved through the use of standardised diagnostic approaches, increased sensitivity and understanding of the impact of BV, and the provision of evidence based advice about known BV related risk factors.

Women's Views and Experiences of the Triggers for Onset of Bacterial Vaginosis and Exacerbating Factors Associated with Recurrence

BACKGROUND

Bacterial vaginosis (BV) is the most common vaginal infection affecting women of childbearing age. While the aetiology and transmissibility of BV remain unclear, there is strong evidence to suggest an association between BV and sexual activity. This study explored women's views and experiences of the triggers for BV onset and factors associated with recurrence.

METHODS

A descriptive, social constructionist approach was chosen as the framework for the study. Thirty five women of varying sexual orientation who had experienced recurrent BV in the past five years took part in semi-structured interviews.

RESULTS

The majority of women predominantly reported sexual contact triggered the onset of BV and sexual and non-sexual factors precipitated recurrence. Recurrence was most commonly referred to in terms of a 'flare-up' of symptoms. The majority of women did not think BV was a sexually transmitted infection however many reported being informed this by their clinician. Single women who attributed BV onset to sex with casual partners were most likely to display self-blame tendencies and to consider changing their future sexual behaviour. Women who have sex with women (WSW) were more inclined to believe their partner was responsible for the transmission of or reinfection with BV and seek partner treatment or change their sexual practices.

CONCLUSION

Findings from this study strongly suggest women believe that BV onset is associated with sexual activity, concurring with epidemiological data which increasingly suggest BV may be sexually transmitted. Exacerbating factors associated with recurrence were largely heterogeneous and may reflect the fact it is difficult to determine whether recurrence is due to persistent BV or a new infection in women. There was however evidence to suggest possible transmission and reinfection among WSW, reinforcing the need for new approaches to treatment and management strategies including male and female partner treatment trials.

Metronidazole vaginal gel 1.3% in the treatment of bacterial vaginosis: a dose-ranging study

OBJECTIVE

Metronidazole vaginal gel (MVG) 0.75% is a US Food and Drug Administration-approved, 5-day treatment for bacterial vaginosis (BV). This study tested the hypothesis that a shorter treatment course at a higher dose (MVG 1.3%) would yield similar efficacy to 5 days of MVG 0.75%.

MATERIALS AND METHODS

This phase 2, multicenter, randomized, controlled, investigator-blinded, dose-ranging study enrolled women with a clinical diagnosis of BV. Patients were assigned to MVG 1.3% once daily for 1, 3, or 5 days or MVG 0.75% once daily for 5 days. The therapeutic cure rate, requiring clinical and bacteriological cure, at the end-of-study visit was determined for the per-protocol population. A Kaplan-Meier analysis was used to estimate median time-to-symptom resolution.

RESULTS

In total, 255 women (mean age = 35 y) were enrolled. The per-protocol population included 189 patients. The therapeutic cure rate was higher in the 1-day (13/43, 30.2%), 3-day (12/48, 25.0%), and 5-day (16/49, 32.7%) MVG 1.3% groups versus the MVG 0.75% group (10/49, 20.4%). Median time-to-resolution of fishy odor was shorter in the 3 MVG 1.3% groups versus the MVG 0.75% group. The 5-day MVG 1.3% group had the lowest rate of symptom return. No clinically important differences were observed in adverse events across treatment groups; most events were mild or moderate in intensity and considered unrelated to treatment. Similar results were found in the modified intent-to-treat population.

CONCLUSIONS

Metronidazole vaginal gel 1.3% applied once daily for 1, 3, or 5 days showed similar efficacy, safety, and tolerability as MVG 0.75% once daily for 5 days.

Mycoplasma hominis and Gardnerella vaginalis display a significant synergistic relationship in bacterial vaginosis

Gardnerella vaginalis plays an important role in bacterial vaginosis (BV,) while the role of genital Mollicutes is less obvious. The diagnosis of BV by use of the current Gram stain Nugent score is also suboptimal for defining the role of Mollicutes that lack a cell wall. Since bacterial load and diversity is an important prerequisite for BV, real-time quantitative polymerase chain reaction (qPCR) assays enable these to be assessed. The purpose of this study was to define the role of genital Mollicutes and potential patterns of synergy with G. vaginalis in women with BV. Vaginal swabs from 130 women categorised by Nugent score as BV (n = 28), intermediate (n = 22) and non-BV (n = 80) were tested against four qPCR TaqMan assays targeting G. vaginalis, Mycoplasma hominis, M. genitalium, Ureaplasma urealyticum and U. parvum. Statistical analyses were used to compare bacterial prevalence and load between the three groups of women. Mycoplasma hominis and G. vaginalis co-infection was significantly more common in BV (60.7 %) compared to intermediate (36.4 %) and non-BV (8.8 %) Nugent scores (p < 0.001). Significantly higher loads of M. hominis (p = 0.001) and G. vaginalis (p < 0.001) were detected in women with BV and the respective loads in M. hominis and G. vaginalis co-infections displayed a significant positive correlation (p < 0.001; r = 0.60). No significant associations were seen with the other Mollicutes. The findings strengthen the evidence of a role for M. hominis in BV and a potential synergy with G. vaginalis. This synergy could be an important trigger of the condition and sexual contact the conduit for the transmission of an otherwise commensal bacterium that could initiate it.

Health Risk Behaviors in a Representative Sample of Bisexual and Heterosexual Female High School Students in Massachusetts

BACKGROUND

Differences in sexual health-related outcomes by sexual behavior and identity remain underinvestigated among bisexual female adolescents.

METHODS

Data from girls (N = 875) who participated in the Massachusetts Youth Risk Behavior Surveillance survey were analyzed. Weighted logistic regression models were fit to examine sexual and psychosocial health by lifetime sexual behavior (behaviorally bisexual vs behaviorally heterosexual) and sexual identity (bisexual vs heterosexual) adjusting for grade and race/ethnicity.

RESULTS

Overall, 10.5% of girls reported lifetime bisexual behavior and 8.1% reported a bisexual identity. Behavior and identity were discordant for bisexual young women as 53.2% of behaviorally bisexual students had a bisexual identity and 46.8% had a heterosexual identity. Bisexual identity and behavior were associated with unprotected intercourse at last sexual encounter, early sexual debut, 4 or more lifetime partners, history of forced/unwanted sex, sexually transmitted infection testing history, past-year depression, and past-month drug use (all ps < .05).

CONCLUSION

Bisexuality, whether defined by identity or behavior, is associated with adverse sexual and psychosocial health outcomes in adolescent girls. Studies that explore wellness across the life span, and are designed to recognize developmental differences burgeoning in adolescence, may provide insights into the differential sexual risk outcomes observed among bisexual girls.

Women Who Have Sex with Women in Kenya and Their Sexual and Reproductive Health

PURPOSE

To describe sexual and reproductive health characteristics of women who have sex with women (WSW) in Kenya's three most populous cities: Kisumu, Mombasa, and Nairobi. Although the last decade has shown an upsurge of health-related research studies in African sexual minority populations, these studies have generally concentrated on the health status of men who have sex with men to the exclusion of WSW. This study presents the first findings on Kenyan WSW's sexual and reproductive health.

METHODS

A community-based, cross-sectional survey was conducted among 280 women who were at least 18 years old, had at least one female sexual partner in the past three years, and were Kenyan residents.

RESULTS

A significant proportion of participants reported that they had at least one male sexual partner in the past three years (38.9%), ever had an abortion (13.2%), been infected with at least one sexually transmitted infection (STI) in the past three years (33.9%), and been tested for HIV at least once (88.9%). Of the women who reported having been tested for HIV, 9.4% (7.5% of the total sample) received a positive test result. Some women noted that they were open with their doctors about their sexual orientation, and that their doctors had not reacted negatively to this information.

CONCLUSION

WSW in Kenya are at risk for negative sexual and reproductive health outcomes, including HIV, STIs, unplanned pregnancy, and unsafe abortion, positioning these women as a critical population for public health efforts. Some WSW actively exercise their agency in making important health decisions. Therefore, this study indicates a need to incorporate WSW's health concerns within Kenyan national health policy programming.

Chlamydia trachomatis infection in African American women who exclusively have sex with women

Little is known about whether Chlamydia trachomatis can be sexually transmitted between women or how often it occurs in women who have sex with women (WSW). We investigated Chlamydia trachomatis prevalence and serum Chlamydia trachomatis-specific antibody responses among African American WSW who reported a lifetime history of sex only with women (exclusive WSW) (n = 21) vs. an age-matched group of women reporting sex with women and men (WSWM) (n = 42). Participants completed a survey, underwent a pelvic examination in which a cervical swab was collected for Chlamydia trachomatis nucleic acid amplification testing (NAAT), and had serum tested for anti-Chlamydia trachomatis IgG1 and IgG3 antibodies using a Chlamydia trachomatis elementary body-based ELISA. No exclusive WSW had a positive Chlamydia trachomatis NAAT vs. 5 (11.9%) WSWM having a positive Chlamydia trachomatis NAAT (p = 0.16). Compared with WSWM, WSW were significantly less likely to be Chlamydia trachomatis seropositive (7 [33.3%] vs. 29 [69%], p = 0.007). Among Chlamydia trachomatis seropositive women, all were seropositive by IgG1, and the magnitude of Chlamydia trachomatis-specific IgG1 responses did not differ in Chlamydia trachomatis-seropositive WSW vs. WSWM. In conclusion, Chlamydia trachomatis seropositivity was relatively common in exclusive African American WSW, though significantly less common than in African American WSWM.
