Genital human papillomavirus infection in women who have sex with women: a review

Human papillomavirus vaccination disparities among U.S. college students: An intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA)

We investigated how gender identity, sexual orientation, and race/ethnicity intersect to shape the social epidemiology of HPV vaccination initiation among U.S. college students. Cross-sectional survey data were from the National College Health Assessment (Fall, 2019-Spring, 2020; N = 65,047). We conducted an intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy by nesting participants within 36 social strata defined using gender identity, sexual orientation, and race/ethnicity. Bayesian multilevel logistic regression models with random intercepts for social strata were fit for HPV vaccination initiation. Intersectional models adjusted for the additive main effects to isolate intersectional interactions, controlling for age and geographic region. Social strata that included cisgender men, transgender women, and non-binary assigned-male-at-birth individuals and strata that included racial/ethnic minorities had a significantly lower likelihood of HPV vaccination initiation relative to strata including cisgender women and non-Hispanic White individuals, respectively, while strata including lesbian/gay and bisexual/pansexual/queer individuals had a significantly higher likelihood of HPV vaccination initiation relative to strata including heterosexual individuals. We also observed substantial between-stratum inequities in the predicted prevalence of HPV vaccination initiation, with estimates ranging from 59.2% for heterosexual, racial/ethnic minority, cisgender men to 87.1% for bisexual/pansexual/queer, racial/ethnic minority, non-binary assigned-female-at-birth individuals. That being said, the majority of the observed between-stratum variance was driven by additive rather than intersectional interaction effects and the discriminatory accuracy of intersectional stratification with respect to predicting HPV vaccination initiation was low. Collectively, our findings point to a need for more universal guidelines and clinician recommendations that promote HPV vaccine uptake for all adolescents, regardless of race/ethnicity, gender identity, sex-assigned-at-birth, or sexual orientation; however, utilizing an intersectional lens will ensure that resulting public health interventions address inequities and center the needs and experiences of multiply marginalized adolescents.

Cervical screening attendance and cervical cancer risk among women who have sex with women

OBJECTIVES

To describe cervical cancer screening participation among women who have sex exclusively with women (WSEW) and women who have sex with women and men (WSWM) compared with women who have sex exclusively with men (WSEM), and women who have never had sex and compare this with bowel (colorectal) and breast screening participation. To explore whether there is evidence of differential stage 3 cervical intraepithelial neoplasia (CIN3) or cervical cancer risk.

METHODS

We describe cervical, bowel and breast cancer screening uptake in age groups eligible for the national screening programmes, prevalent CIN3 and cervical cancer at baseline, and incident CIN3 and cervical cancer at five years follow-up, among 218,674 women in UK Biobank, a cohort of healthy volunteers from the UK.

RESULTS

Compared with WSEM, in adjusted analysis [odds ratio (95% confidence interval)], WSEW 0.10 (0.08-0.13), WSWM 0.73 (0.58-0.91), and women who have never had sex 0.02 (0.01-0.02) were less likely to report ever having attended cervical screening. There were no differences when considering bowel cancer screening uptake (p = 0.61). For breast cancer screening, attendance was lower among WSWM 0.79 (0.68 to 0.91) and women who have never had sex 0.47 (0.29-0.58), compared with WSEM. There were incident and prevalent cases of both CIN3 and cervical cancer among WSEW and WSWM. Compared with WSEM with a single male partner, among WSEW there was a twofold increase in CIN3 1.91 (1.01 to 3.59); among WSWM with only one male partner, this was 2.25 (1.19 to 4.24).

CONCLUSIONS

These findings highlight the importance of improving uptake of cervical screening among all women who have sex with women and breast screening among WSWM and women who have never had sex.

Cervical Cancer Screening and Human Papillomavirus Vaccination among Korean Sexual Minority Women by Sex of Their Sexual Partners

Cervical cancer-preventive behaviors in Korean sexual minority women (SMW) are underexplored. We aimed to assess the differences in cervical cancer screening uptake and completion of human papillomavirus (HPV) vaccination among Korean SMW by sex of their sexual partners. This cross-sectional study used data from the 2017 Korean Sexual Minority Women's Health Study; we included Korean lesbian and bisexual women aged ≥20 years. They were divided into three groups: SMW with more than one male sexual partner (male only/both), SMW with only female sexual partners (female-only), or no sexual partner (no partner). Among the 671 participants, 266 (39.6%), 294 (43.8%), and 111 (16.5%) belonged to the male-only/both, female-only, and no partner groups, respectively. Compared to the male-only/both group, the female-only group was significantly less likely to have undergone cervical cancer screening (Adjusted odds ratio (AOR) = 0.24, 95% confidence interval (CI) = 0.15-0.37) and to have completed HPV vaccinations (AOR = 0.58, 95% CI = 0.37-0.91). In conclusion, Korean SMW with only female sexual partners had lower cervical cancer screening and HPV vaccination completion rates than SMW who had male sexual partners. More extensive efforts are needed to improve cervical cancer-preventive behaviors among Korean SMW.

Reasons Lesbian and Bisexual Adolescent Girls Have or Might Have Sex with Females or Males: Implications for Discordance between Sexual Identity and Behaviors and for Prevention of Pregnancy and STIs

We examined reasons lesbian and bisexual adolescent girls have sex or, if sexually inexperienced, might have sex with girls or boys, and the role of internalized homonegativity in these relations and among lesbians. Girls were recruited online and classified as lesbian (n = 129) or bisexual (n = 193); the classification was validated. Love and pleasure were common reasons for having sex with girls, although more lesbian girls (LG) than bisexual girls (BG) endorsed love. BG, relative to LG, had sex with girls because they were curious or wanted to verify their sexual identity. Love and pleasure were motives for having sex with boys for BG. They were common reasons for potentially having sex with either sex among sexually inexperienced girls, but both were more likely for BG than LG for sex with boys. Internalized homonegativity did not mediate the relation between sexual identity and reasons for sex, but LG just with male partners were more homonegative than LG just with female partners. The findings indicate that LG and BG should not be combined into a single group, provide insights into the discordance between sexual identity and behaviors, and have implications for reducing risk for pregnancy and sexually transmitted infections among sexual minority girls.

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.

Cancer diagnoses among lesbian, gay, and bisexual adults: results from the 2013-2016 National Health Interview Survey

PURPOSE

The objective of this study was to compare cancer diagnoses by age, gender, and sexual orientation.

METHODS

This study used data on 129,431 heterosexual adults and 3,357 lesbian, gay, and bisexual (LGB) adults in the 2013-2016 National Health Interview Survey. Logistic regression models compared the prevalence of cancer diagnoses by sexual orientation while controlling for demographics, socioeconomic status, and health profiles. Then, using coefficients from fully adjusted models, we estimated average marginal effects to compare the probability of a cancer diagnosis by sexual orientation across five age categories.

RESULTS

After controlling for demographic and socioeconomic characteristics, gay men (odds ratio [OR] 1.54; 95% confidence interval [CI] 1.10-2.18) were more likely to have been diagnosed with cancer compared to heterosexual men, and bisexual women (OR 1.70; 95% CI 1.16-2.48) were more likely to have been diagnosed with cancer compared to heterosexual women. Gay men aged 65 years and older were 6.0% points (p < 0.05) more likely to be diagnosed with cancer compared to heterosexual men of the same age. Bisexual women aged 65 years and older were 7.6% points (p < 0.05) more likely to be diagnosed with cancer compared to women of the same age.

CONCLUSIONS

Some sexual minorities may be at greater risk for cancer (or having a personal history of cancer) compared to heterosexuals. More research on cancer detection, treatment, and survivorship in sexual minorities is critically needed. Health care providers and public health practitioners should be aware of the unique health care needs in LGB adults, including their elevated cancer risks.

Why Girls Choose Not to Use Barriers to Prevent Sexually Transmitted Infection During Female-to-Female Sex

PURPOSE

Using data from a national qualitative study of lesbian, bisexual, and other sexual minority adolescent girls in the U.S., this study examined their awareness of the risk of sexually transmitted infection (STI) and opportunities for barrier use.

METHODS

Online asynchronous focus groups were conducted with lesbian and bisexual (LB) girls ages 14-18 years. Girls were assigned to online groups based on their self-identified sexual identity and whether they were sexually experienced or not. Two moderators posed questions and facilitated online discussions. Interpretive description analysis conducted by multiple members of the research team was used to categorize the results.

RESULTS

Key factors in girls' decisions not to use barriers with female partners concerned pleasure, sex of sexual partner, lack of knowledge of sexual risk or of barrier use for female-to-female sexual activities, and use of STI testing as a prevention tool.

CONCLUSIONS

Addressing knowledge and access gaps is an important first step for improving sexual health. Prevention priorities should focus on helping LB girls understand their risk of STI transmission in both opposite and same-sex relationships. Tailoring messaging to move beyond heteronormative scripts is critical to engaging LB girls and equipping them with the skills and knowledge to have safer sex regardless of the sex of their partner.

[Barriers to sexual health care in Argentina: perception of women who have sex with women]

Objective The objective is to describe the barriers to sexual health care of Women Who Have Sex with Women (WSW) in Argentina during 2013. Methods A cross-sectional, descriptive and quantitative study. An online survey was conducted using the Internet, in the period of April-July 2013, with homosexual and bisexual women over 18 living in Argentina, making use of the snowball methodology. Results A total of 161 women were surveyed. The results showed that 97.5 % had previously visited a doctor. The doctor did not ask about their sexual orientation in 82.8 % of cases. 93.6 % of the surveyed did not receive information about STDs; 83.8 % perceive little/no risk regarding STDs. 48.4 % are unaware of the methods of protection of STDs among women and 51.6 % obtained this information from websites and friends. 77.5 % reported not using protection methods. The main reasons were: stable partner, discomfort and the inability to acquire them. Discussion The results of this research allow for identifying the low perception among WSW regarding STDs, and the difficulty of approaching health professionals about this subject.

Sexual orientation and sexual health services utilization among women in the United States

Although sexual minority women are at risk of sexually transmitted infections (STIs) and cervical cancer, few nationally representative studies have assessed sexual orientation disparities in sexual health care among women. Using data from the 2011-2013 and 2013-2015 waves of the National Survey of Family Growth, which provide a national probability sample of U.S. women aged 15-44years (N=11,300), we used multivariable logistic regression to examine the associations between sexual behavior and sexual identity (modeled separately) and STI testing in the past year, Pap test use in the last 3years, lifetime HIV testing, and lifetime human papillomavirus (HPV) testing. Women with male and female lifetime sexual partners had higher adjusted odds of being tested for STIs ([odds ratio:] 1.61; [95% confidence interval:] 1.37-1.89), HIV (1.66; 1.29-2.14), and HPV (1.79; 1.41-2.25) and similar adjusted odds of obtaining a Pap test (0.98; 0.76-1.27) than women with only male lifetime sexual partners. Self-identified bisexual women had higher adjusted odds of obtaining an STI (1.43; 1.10-1.86) and HIV (1.69; 1.24-2.30) test but lower adjusted odds of obtaining a Pap test in the last 3years (0.66; 0.47-0.93) than heterosexual-identified women. Women with only female lifetime sexual partners had lower adjusted odds of receiving an STI (0.14; 0.07-0.28) and Pap (0.10; 0.03-0.27) test than women with only male lifetime sexual partners. Results comparing self-identified lesbian and heterosexual women were similar. Health care facilities should monitor and address sexual orientation disparities in women's sexual health care and ensure the provision of high-quality sexual health services to all women.

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.

Sex of Sexual Partners and Human Papillomavirus Vaccination Among U.S. Girls and Women

INTRODUCTION

Girls and women are at risk of human papillomavirus (HPV) infection and cervical cancer from male and female sexual partners throughout the life course. However, no study has assessed how sex of sexual partners, a dimension of sexual orientation, may relate to HPV vaccination among girls and women.

METHODS

In 2014, data from the 2006-2010 National Survey of Family Growth were used to conduct logistic regression analyses estimating the relationship between sex of lifetime and past-year sexual partners and HPV vaccine awareness and initiation among U.S. girls and women aged 15-25 years (N=3,253).

RESULTS

Among U.S. girls and women aged 15-25 years, the prevalence of HPV vaccine awareness and HPV vaccine initiation was 84.4% and 28.5%, respectively. Adjusting for sociodemographic factors, participants with only female past-year sexual partners had significantly lower odds of initiating HPV vaccination relative to those with only male past-year sexual partners (OR=0.16, 95% CI=0.05, 0.55). Similarly, respondents with no lifetime (OR=0.65, 95% CI=0.46, 0.92) or past-year (OR=0.69, 95% CI=0.50, 0.94) sexual partners had significantly lower adjusted odds of HPV vaccine initiation compared with those with only male sexual partners. No difference was apparent in the odds of initiating HPV vaccination between participants with male and female sexual partners and those with only male sexual partners.

CONCLUSIONS

Medical and public health professionals should ensure that girls and women with only female or no sexual partners are included in HPV vaccine education and promotion efforts.

Primary care of women who have sex with women. Recommendations from the research

Research on women who have sex with women has increased in the last decade. Attention has been brought to this group of women through the IOM report, which noted a lack of research related to their care. Most of the research has not been published in nursing literature. This article reviews this literature with recommendations for primary care practice.

Sexual Orientation Identity Disparities in Awareness and Initiation of the Human Papillomavirus Vaccine Among U.S. Women and Girls: A National Survey

BACKGROUND

Lesbians and bisexual women are at risk for human papillomavirus (HPV) infection from female and male sexual partners.

OBJECTIVE

To examine the association between sexual orientation identity and HPV vaccination among U.S. women and girls.

DESIGN

Cross-sectional, using 2006-2010 National Survey of Family Growth data.

SETTING

U.S. civilian noninstitutionalized population.

PARTICIPANTS

The 2006-2010 National Survey of Family Growth used stratified cluster sampling to establish a national probability sample of 12,279 U.S. women and girls aged 15 to 44 years. Analyses were restricted to 3253 women and girls aged 15 to 25 years who were asked about HPV vaccination.

MEASUREMENTS

Multivariable logistic regression was used to obtain prevalence estimates of HPV vaccine awareness and initiation adjusted for sociodemographic and health care factors for each sexual orientation identity group.

RESULTS

Among U.S. women and girls aged 15 to 25 years, 84.4% reported having heard of the HPV vaccine; of these, 28.5% had initiated HPV vaccination. The adjusted prevalence of vaccine awareness was similar among heterosexual, bisexual, and lesbian respondents. After adjustment for covariates, 8.5% (P = 0.007) of lesbians and 33.2% (P = 0.33) of bisexual women and girls who had heard of the vaccine had initiated vaccination compared with 28.4% of their heterosexual counterparts.

LIMITATION

Self-reported, cross-sectional data, and findings may not be generalizable to periods after 2006 to 2010 or all U.S. lesbians aged 15 to 25 years (because of the small sample size for this group).

CONCLUSION

Adolescent and young adult lesbians may be less likely to initiate HPV vaccination than their heterosexual counterparts. Programs should facilitate access to HPV vaccination services among young lesbians.

Women Who Have Sex with Women Living in Low- and Middle-Income Countries: A Systematic Review of Sexual Health and Risk Behaviors

Women who have sex with women (WSW) have long been considered at low risk of acquiring and transmitting HIV and other sexually transmitted infections (STIs). However, limited research has been conducted on WSW, especially those living in low-and middle-income countries (LMICs). We reviewed available research on sexual health and risk behaviors of WSW in LMICs. We searched CINAHL, Embase, and PubMed for studies of WSW in LMICs published between January 1, 1980, and December 31, 2013. Studies of any design and subject area that had at least two WSW participants were included. Data extraction was performed to report quantifiable WSW-specific results related to sexual health and risk behaviors, and key findings of all other studies on WSW in LMICs. Of 652 identified studies, 56 studies from 22 countries met inclusion criteria. Reported HIV prevalence among WSW ranged from 0% in East Asia and Pacific and 0%-2.9% in Latin America and the Caribbean to 7.7%-9.6% in Sub-Saharan Africa. Other regions did not report WSW HIV prevalence. Overall, many WSW reported risky sexual behaviors, including sex with men, men who have sex with men (MSM), and HIV-infected partners; transactional sex; and substance abuse. WSW are at risk for contracting HIV and STIs. While the number of research studies on WSW in LMICs continues to increase, data to address WSW sexual health needs remain limited.

Sexual orientation disparities in Papanicolaou test use among US women: the role of sexual and reproductive health services

We investigated sexual orientation disparities in Papanicolaou screening among US women aged 21 to 44 years (n = 9581) in the 2006 to 2010 National Survey of Family Growth. The odds ratios for lesbian versus heterosexual women and women with no versus only male sexual partners were 0.40 and 0.32, respectively, and were attenuated after adjustment for sexual and reproductive health (SRH) care indicators. Administering Papanicolaou tests through mechanisms other than SRH services would promote cervical cancer screening among all women.

Understanding cervical cancer screening among lesbians: a national survey

Background

Lesbians have low rates of cervical cancer screening, even though they are at risk of developing the disease. The aim of this study was to examine cervical cancer screening behaviors in a national sample of lesbians.

Methods

A standardized internet survey was sent to 3,000 self-identified lesbians to assess cervical cancer screening behaviors and barriers to screening. The sample consisted of 1,006 respondents.

Results

Sixty-two percent of the weighted sample of respondents were routine screeners. Lack of a physician referral (17.5%) and lack of a physician (17.3%) were the most commonly-cited top reasons for lack of screening. Adjusting for age, education, relationship status, employments status, and insurance status, women who had disclosed their sexual orientation to their primary care physician (adjusted odds ratio [OR] 2.84 [95% confidence interval 1.82-4.45]) or gynecologist (OR 2.30 [1.33-3.96]) had greater odds of routine screening than those who did not. Those who knew that lack of Pap testing is a risk factor for cervical cancer were also more likely to be routine screeners (OR 1.95 [1.30-2.91]), although no association with screening was apparent for women who had more knowledge of general cervical cancer risk factors. Physician recommendation appeared to be a potent determinant of regular screening behavior. Routine screeners perceived more benefits and fewer barriers to screening, as well as higher susceptibility to cervical cancer.

Conclusions

Some women who identify as lesbian are at a potentially elevated risk of cervical cancer because they are not routinely screened. Evidence-based interventions should be developed to address critical health beliefs that undermine participation in screening. Given the value placed on physician recommendation, patient-provider communication may serve as the optimal focus of effective intervention.

Barriers to cervical cancer screening among lesbians

OBJECTIVE

To evaluate cervical cancer screening practices and barriers to screening in a sample of lesbians.

METHODS

Cross-sectional survey data were collected from 225 self-identified lesbians who completed an online questionnaire.

RESULTS

Of the respondents, 71% reported receiving a Pap screening test in the past 24 months (routine screeners), and 29% reported receiving a Pap screening test >24 months ago or never (nonroutine screeners). Routine screeners were more likely to be older (p < 0.01), white (p = 0.04), and college graduates (p < 0.01) than nonroutine screeners. Nonroutine screeners were more likely to delay seeking healthcare because of fear of discrimination (p < 0.01) and were less likely than routine screeners to disclose orientation to their primary care physician (p < 0.01). After adjusting for age, race, and education, nonroutine screeners perceived fewer benefits from (p < 0.01) and more barriers (p < 0.01) to Pap screening tests and were less knowledgeable about screening guidelines (p < 0.01) than routine screeners, but there was no difference in perceived susceptibility (p = 0.68), perceived seriousness (p = 0.68), or risk factor knowledge (p = 0.35) of cervical cancer.

CONCLUSIONS

Many lesbians do not screen for cervical cancer at recommended rates. Nonroutine screeners perceive fewer benefits, more barriers, and more discrimination and are less knowledgeable about screening guidelines than routine screeners.

Measuring cervical cancer risk: development and validation of the CARE Risky Sexual Behavior Index

OBJECTIVES

To develop and validate a risky sexual behavior index specific to cervical cancer research.

METHODS

Sexual behavior data on 428 women from the Community Awareness Resources and Education (CARE) study were utilized. A weighting scheme for eight risky sexual behaviors was generated and validated in creating the CARE Risky Sexual Behavior Index. Cutpoints were then identified to classify women as having a low, medium, or high level of risky sexual behavior.

RESULTS

Index scores ranged from 0 to 35, with women considered to have a low level of risky sexual behavior if their score was less than six (31.3% of sample), a medium level if their score was 6–10 (30.6%), or a high level if their score was 11 or greater (38.1%). A strong association was observed between the created categories and having a previous abnormal Pap smear test (p < 0.001).

CONCLUSIONS

The CARE Risky Sexual Behavior Index provides a tool for measuring risky sexual behavior level for cervical cancer research. Future studies are needed to validate this index in varied populations and test its use in the clinical setting.

Perceived risk for cancer in an urban sexual minority

Lesbians, gay men, and bisexuals are a sexual minority experiencing elevated cancer risk factors and health disaparites, e.g., elevated tobacco use, disproportionate rates of infection with human immunodeficiency virus. Little attention has been paid to cancer prevention, education, and control in sexual minorities. This study describes cancer risk perceptions and their correlates so as to generate testable hypotheses and provide a foundation for targeting cancer prevention and risk reduction efforts in this high risk population. A cross-sectional survey of affiliates of a large urban community center serving sexual minority persons yielded a study sample of 247 anonymous persons. The survey assessed demographics, absolute perceived cancer risk, cancer risk behaviors, desired lifestyle changes to reduce cancer risk, and psychosocial variables including stress, depression, and stigma. Univariate and multivariate nonparametric statistics were used for analyses. The sample was primarily white non-Hispanic, middle-aged, and > 80% had at least a high school education. Mean values for absolute perceived cancer risk (range 0-100% risk), were 43.0 (SD = 25.4) for females, and for males, 49.3 (SD = 24.3). For females, although the multivariate regression model for absolute perceived cancer risk was statistically significant (P < .05), no single model variable was significant. For men, the multivariate regression model was significant (P < .001), with endorsement of "don't smoke/quit smoking" to reduce personal cancer risk (P < .001), and greater number of sexual partners (P = .054), positively associated with absolute perceived risk for cancer. This study provides novel data on cancer risk perceptions in sexual minorities, identifying correlates of absolute perceived cancer risk for each gender and several potential foci for cancer prevention interventions with this at-risk group.

[How did I contract human Papillomavirus (HPV)?]

More than 120 genotypes have been identified among the Papillomavirus (HPV) family. These viruses are ubiquitary with skin or mucous membrane tropism and cause various pathologies from wart to neoplasia. HPV family is classified according to their tropism. Genital HPV infection is considered as the most frequent sexually transmitted disease in the world. Seventy-five percent of women will be in contact with HPV at least one time in their life. HPV is usually transmitted through direct skin-to-skin contact, more often during penetrative genital contact. Other types of genital contact in the absence of penetration can lead to HPV infection, but those routes of transmission are much less common than sexual intercourse. However, virgins (<2 % of cases) and young children can present HPV infection, suggesting other routes of transmission than sexual intercourse. HPV infection could occur during delivery; vaginal deliveries appear to promote this transmission in comparison with cesarean section. But cesarean section do not completely protect against contamination risk. In utero, vertical transmission has been suggested by different studies but with lack of evidence. HPV infection can be detected on inanimate objects, such as clothing or environmental surfaces. However, transmission is not known to occur by this route. More detailed knowledges of the transmission route of HPV infection will enable to get prevention more effective.

[Access to sexual health care for women who have sex with women in São Paulo, Brazil]

This article focuses on the relationship between health care for women who have sex with women and representations of gender, sexuality, and the body. The study used ethnographic observation and in-depth interviews held from 2003 to 2006, with 30 women ranging from 18 to 45 years of age, belonging to different social segments, backgrounds, and sexual identities, living in Greater Metropolitan São Paulo. Analysis of the material pointed to greater difficulty in accessing gynecological care for lower-income women, those who had never had sex with men, or those with masculine body language. Not only the negative representations and experiences in relation to health services, but also identity constructions concerning gender and sexuality, are related to difficulties in accessing health care. Although a large share of the relevant international literature emphasizes the relationship between homophobia and decreased access to health services, the findings suggest that although situations involving discrimination are a reality, they were not considered impediments to the search for care, and were more associated with reporting of erotic practices and preferences at the services.

Understandings of Cervical Screening in Sexual Minority Women: A Q-Methodological Study

Discursive perspectives argue that cervical screening carries social and moral meaning. Overlooked by research into the health needs of sexual minority women, previous literature that has examined uptake of cervical screening has instead targeted increasing attendance via information and service provision. In order to explore the diversity of meanings that British sexual minority women have about cervical screening, the Q-sorts of 34 sexual minority women were factor analysed by-person and rotated to simple structure using Varimax. The five factors are interpreted and discussed relative to competing discourses on information provision within cervical screening. The five accounts are labelled ‘cervical screening is’: an essential health check that women have the right to refuse; a woman’s health entitlement; a vital test but degrading experience; a sensible thing to do; and an unnecessary imposition for some women. Critical approaches to informed choice are explored with attention to recent developments in cervical cancer prevention. Findings highlighting the need for affirmation of diversity within healthcare are considered in relation to existing criteria for UK national screening programmes.

Role of gender in sexual behaviours and response to education in sexually transmitted infections in 17-year-old adolescents

OBJECTIVE

to investigate gender differences in high school students with respect to sexual risk behaviours, and their perceptions of the effect of an educational programme on sexually transmitted infections (STIs). In addition, this study aimed to investigate differences between students in programmes preparing for university compared with vocational programmes. PARTICIPANTS, SETTING AND DESIGN: second-year high school adolescents from two communities in south-west Sweden were invited to participate in the study, and completed a questionnaire on sexual experience, sexual risk behaviours and the impact of the educational programme on STIs.

FINDINGS

males took less responsibility for STI prevention than females. Furthermore, males perceived themselves to be less influenced by the STI education than females. Females had more experience of same-sex sexuality than males.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

males take less responsibility for STI prevention than females. When planning STI education, it is important to consider gender, traditions and various learning styles. If STI education fails to reach males, the prevalence of these infections will continue to increase.

Comparing knowledge and perceived risk related to the human papilloma virus among Australian women of diverse sexual orientations

OBJECTIVES

The study compared levels of awareness of human papilloma virus (HPV) as a sexually transmissible infection (STI) between women of different sexual orientations. It also examined self-reported risk factors for HPV infection, perceived level of personal risk, and willingness to have the HPV vaccine.

METHODS

Recruitment occurred through community sampling and data was collected using a self-completion questionnaire.

RESULTS

A convenience sample of 349 women completed the questionnaire in early 2007, 309 were sexually active; 47.6% had lifetime sexual partners of both genders, 26.9% had only male partners, and 25.5% had only female partners. Women with partners of both genders were more likely to have ever had a pap test but were also more likely to report an abnormal result (OR 3.19) than women with only male partners. Only 68% of the sample had heard of HPV and women with partners of both genders were significantly more likely to be aware than women with only male partners (OR 2.56). Forty-four per cent did not know how HPV was transmitted and less than half correctly identified HPV-associated clinical problems, with no differences according to gender of partners. The majority of women had risk factors for HPV, however, few felt personally at risk.

CONCLUSIONS

The very low personal risk perception for HPV, particularly among women who have female and male sexual partners, suggests the need for targeted education for this group regarding HPV transmission and prevention.

IMPLICATIONS

Health promotion regarding HPV should be broadened to specifically include information about HPV as an STI between women.

Absent sexual scripts: lesbian and bisexual women's knowledge, attitudes and action regarding safer sex and sexual health information

Despite recent evidence demonstrating that lesbian and bisexual women are at risk of sexually transmitted infections (STIs), there is a common perception that STIs cannot be transmitted between women. This paper reports on a study in which a self-report questionnaire, completed by over 300 lesbian and bisexual women and a comparison group of heterosexual women, was undertaken to determine lesbian and bisexual women's levels of knowledge about the human papillomavirus (HPV) and their attitudes toward the HPV vaccine and cervical smear testing. Alongside this, a series of in-depth interviews with lesbian and bisexual women explored how they perceive their level of HPV risk, the reasons why they do or do not feel at risk and how they manage their sexual health in relation to their lesbian or bisexual identity. The study concludes that lesbians generally feel at low risk for STIs because they are excluded from dominant sexual scripts that inform the negotiation of safer sex practice. Lesbians are unlikely to engage with sexual health promotion targeted toward gay men or heterosexual women, yet lesbian-specific sexual health promotion does not adequately construct an alternate discourse on safer sex that lesbians can relate to their own sexual practice.

Lesbians and cancer: an overlooked health disparity

OBJECTIVE

To evaluate the breast, cervical, ovarian, lung, and colorectal cancer literatures using a novel application of the cancer disparities grid to identify disparities along domains of the cancer continuum focusing on lesbians as a minority population.

METHODS

Computerized databases were searched for articles published from 1981 to present. Cumulative search results identified 51 articles related to lesbians and disparities, which were classified by domain.

RESULTS

The majority of articles identified were related to breast and cervical cancer screening. Barriers to adequate screening for both cancers include personal factors, poor patient-provider communication, and health care system factors. Tailored risk counseling has been successful in increasing lesbian's mammography and Pap screening. Ovarian, lung, and colorectal cancer have been virtually unexplored in this population. An "Adjustment to Illness/Quality of Life" domain was added to capture literature on psychosocial aspects of cancer.

CONCLUSIONS

This review revealed a lack of research for specific cancers and for specific aspects of the cancer continuum. The limited number of studies identified focused on issues related to screening/prevention in cervical and breast cancers, with almost no attention to incidence, etiology, diagnosis, treatment, survival, morbidity, or mortality. We present implications for social and public health policy, research, and prevention.

Women who report having sex with women: British national probability data on prevalence, sexual behaviors, and health outcomes

OBJECTIVES

We estimated the prevalence of same-sex experience among women and compared women reporting sex with women and men and women reporting sex exclusively with women with women reporting sex exclusively with men, in terms of sociodemographics and sexual, reproductive, and general health risk behaviors and outcomes.

METHODS

We used a British probability survey (n=6399 women, aged 16 to 44 years) conducted from 1999 to 2001 with face-to-face interviewing and computer-assisted self-interviewing.

RESULTS

We found that 4.9% of the women reported same-sex partner(s) ever; 2.8% reported sex with women in the past 5 years (n=178); 85.0% of these women also reported male partner(s) in this time. Compared with women who reported sex exclusively with men, women who reported sex with women and men reported significantly greater male partner numbers, unsafe sex, smoking, alcohol consumption, and intravenous drug use and had an increased likelihood of induced abortion and sexually transmitted infection diagnoses (age-adjusted odds ratios=3.07 and 4.41, respectively).

CONCLUSIONS

For women, a history of sex with women may be a marker for increased risk of adverse sexual, reproductive, and general health outcomes compared with women who reported sex exclusively with men. A nonjudgmental review of female patients' sexual history should help practitioners discuss risks that women may face.

Health Care Recommendations for Lesbian Women

OBJECTIVE

To review research literature to provide clinicians with data-based recommendations for care of lesbians.

DATA SOURCES

Medline searches and references from selected articles with the search term "lesbian health."

STUDY SELECTION

Literature was selected whether lesbian or women who have sex with women was utilized as a category in the study and results were available on this population.

DATA EXTRACTION

Data were organized according to specific health problems noted frequently in the research articles.

DATA SYNTHESIS

Lesbians have previously been invisible in health services and research, but in several areas, data now exists on which to base care.

CONCLUSIONS

Lesbians are now more comfortable "coming out" to providers but continue to have lower screening rates than other women. Risk is especially high in this population for cancer, heart disease, depression, and alcohol abuse. Adolescent lesbians are especially at risk for smoking and suicide/depression.

Multisystem Factors Contributing to Disparities in Preventive Health Care Among Lesbian Women

Lesbians experience significant health disparities in preventive care utilization and health outcomes compared to heterosexual women. In this study, a multisystems ecologic approach is taken to identify barriers to access, treatment, and preventive care among lesbian women. Recommendations include increasing knowledge of lesbian health care needs, developing cultural sensitivity and competence in communication and care for lesbian women, and creating practice environments that convey respect, acceptance, and welcome to all women, regardless of sexual orientation.

Barriers to infectious disease care among lesbians

Despite the considerable number of women in the United States who identify as lesbian, few data exist that address lesbians' health needs. The Institute of Medicine emphasized that data on sexually transmitted infections, Pap smear screening, and cervical dysplasia among lesbians were needed to guide clinical practice, policy development, and patient education. Use of surveillance data for this purpose is limited because risk classifications exclude same-gender sex among women or subsume it under behavior considered as higher risk. However, sexual transmission of human papillomavirus, HIV, Treponema pallidum, and Trichomonas vaginalis between women has been reported. Data indicate that lesbians receive routine Pap smear screening less frequently than is optimal. Moreover, lesbians commonly report previous pregnancy, induced abortion, and hormonal contraceptive use. Education of lesbians and their care providers should counter assumptions that sex between women confers no risk for transmission of sexually transmitted infections, and lesbians should receive Pap smears according to current guidelines.

[Non heterosexual patients in gynaecology]

Visible or invisible? Despite a growing tolerance of homosexuality over the past 30 years, little research on lesbian health or lesbian healthcare behaviour has been conducted in France. We have reviewed American studies in an attempt to investigate the relationship between sexual orientation and general and gynaecological health. In this paper, we stress the importance of trust in the doctor-patient relationship.

Human papillomavirus infections: diagnosis, treatment, and hope for a vaccine

HPV infections are common, with millions of Americans infected. Common gynecologic manifestations of HPV infection include genital warts and cervical neoplasia. The CDC recently issued guidelines for the treatment of genital warts. Gynecologists should be familiar with these therapies and their potential short-comings. A recently reported clinical trial has raised hopes that HPV and its sequelae may be prevented by vaccination.

External genital warts: diagnosis, treatment, and prevention

External genital warts (EGWs) are visible warts that occur in the perigenital and perianal regions. They are due primarily to non-oncogenic human papillomavirus (HPV) types, usually types 6 and 11. Physical examination assisted by bright light and magnification is the recommended approach for primary diagnosis. Biopsy is indicated when EGWs are fixed to underlying structures or discolored or when standard therapies are not effective. Recurrences are common, and there is no single treatment that is superior to others. Among women with atypical squamous cells, molecular HPV testing may be useful in determining who should be referred for colposcopy. Condoms may provide some protection against HPV-related diseases and thus are recommended in new sexual relationships and when partnerships are not mutually monogamous. Because the efficacy of cesarean section in preventing vertical transmission of HPV infection from women with EGWs to their progeny has not been proved, it is not recommended.

Lesbian health research: a review and recommendations for future research

Prior to 1990 lesbians were "invisible" in health care research. Researchers who asked questions specifically about lesbian health concerns were rare, and the burgeoning research on women's health seldom included variables that measured sexual orientation or behavior. In the last decade, however, lesbian health has emerged as a major area of study. A 1999 Institute of Medicine (IOM) report on Lesbian Health has outlined the challenges and gaps in this area of research and has called for focus and funding on specific areas of need. In this article I review research on lesbian health, discuss methodological issues specific to this area of research, and summarize the recommendations of the IOM report.
