Influence of hormonal contraceptive use and health beliefs on sexual orientation disparities in Papanicolaou test use

Socioeconomic Inequities in Pap Test Use Among Black Women in the United States: An Intersectional Approach

INTRODUCTION

Research investigating racialized inequities in cervical cancer screening has rarely considered the influence of socioeconomic position (SEP), a key social determinant of health that intersects with race/ethnicity and racism. Thus, data on socioeconomic inequities in Pap test use within racialized groups-including Black women, who are at elevated risk of cervical cancer morbidity and mortality-are limited.

METHODS

Using 2011-2019 data from the National Survey of Family Growth and guided by an intersectional framework, we used multivariable logistic regression to examine the association between educational attainment, employment status, and income and the adjusted odds of Pap test use in the last 3 years among Black U.S. women.

RESULTS

Compared to Black women with a bachelor's degree or greater, those with less than a high school diploma ([odds ratio] = 0.45; [95% confidence interval] 0.31-0.67) and a high school diploma/GED (0.57; 0.40-0.81) had significantly lower odds of Pap test use, adjusting for sociodemographic factors. Unemployed women had significantly lower adjusted odds of Pap test use compared to employed women (0.67; 0.50-0.89), and women living below 100% of the federal poverty level (FPL) had significantly lower adjusted odds of Pap test use relative to those living at or above 300% FPL (0.63; 0.45-0.88).

CONCLUSION

Low-SEP Black women had significantly lower adjusted odds of Pap test use relative to their higher SEP counterparts. Interventions that address both racism and economic barriers to care are needed to facilitate access to regular cervical cancer screening among low-SEP Black women.

Disparities in Mortality by Sexual Orientation in a Large, Prospective Cohort of Female Nurses

Importance

Extensive evidence documents health disparities for lesbian, gay, and bisexual (LGB) women, including worse physical, mental, and behavioral health than heterosexual women. These factors have been linked to premature mortality, yet few studies have investigated premature mortality disparities among LGB women and whether they differ by lesbian or bisexual identity.

Objective

To examine differences in mortality by sexual orientation.

Design, Setting, and Participants

This prospective cohort study examined differences in time to mortality across sexual orientation, adjusting for birth cohort. Participants were female nurses born between 1945 and 1964, initially recruited in the US in 1989 for the Nurses' Health Study II, and followed up through April 2022.

Exposures

Sexual orientation (lesbian, bisexual, or heterosexual) assessed in 1995.

Main Outcome and Measure

Time to all-cause mortality from assessment of exposure analyzed using accelerated failure time models.

Results

Among 116 149 eligible participants, 90 833 (78%) had valid sexual orientation data. Of these 90 833 participants, 89 821 (98.9%) identified as heterosexual, 694 (0.8%) identified as lesbian, and 318 (0.4%) identified as bisexual. Of the 4227 deaths reported, the majority were among heterosexual participants (n = 4146; cumulative mortality of 4.6%), followed by lesbian participants (n = 49; cumulative mortality of 7.0%) and bisexual participants (n = 32; cumulative mortality of 10.1%). Compared with heterosexual participants, LGB participants had earlier mortality (adjusted acceleration factor, 0.74 [95% CI, 0.64-0.84]). These differences were greatest among bisexual participants (adjusted acceleration factor, 0.63 [95% CI, 0.51-0.78]) followed by lesbian participants (adjusted acceleration factor, 0.80 [95% CI, 0.68-0.95]).

Conclusions and Relevance

In an otherwise largely homogeneous sample of female nurses, participants identifying as lesbian or bisexual had markedly earlier mortality during the study period compared with heterosexual women. These differences in mortality timing highlight the urgency of addressing modifiable risks and upstream social forces that propagate and perpetuate disparities.

Yet Again Conversations Matter: The Importance of Interpersonal Discussions, Educational Campaigns, and Advertising on Cannabis-Related Risk Perceptions, Attitudes, and Intentions in At-Risk Young Adults

The present study seeks to evaluate the relationships between cannabis-related communication and outcomes of interest such as cannabis-related risk perceptions, attitudes, and behaviors among young adults. Young adults who were at risk for cannabis use were surveyed online in 2020. Results showed that exposure to online educational messages was associated with higher intentions of engaging in peer intervention, while exposure to online advertising was related to higher intention to use cannabis. Anti-cannabis interpersonal discussion was associated with increased risk perceptions, less favorable cannabis attitudes, and a higher likelihood of peer intervention. More pro-cannabis interpersonal discussion was associated with decreased risk perceptions, more favorable cannabis attitudes, higher use intention, and decreased likelihood of peer intervention. In addition, pro-cannabis interpersonal discussion mediated the relationship between exposure to advertising and cannabis risk perceptions, intentions to use cannabis, attitudes about cannabis, and the likelihood of peer intervention. In contrast, anti-cannabis interpersonal discussion mediated the relationship between exposure to educational messages online and cannabis risk perceptions and the likelihood of peer intervention. These findings underscore the need to regulate online cannabis marketing and the importance of investing in online education campaigns to increase public understanding of the risks associated with cannabis consumption in young adulthood.

The intersection of sexual orientation with race and ethnicity in cervical cancer screening

BACKGROUND

Cervical cancer screening is recommended for those with a cervix who are 21 to 65 years old, with specific timelines being dependent on individual risk. This study compared rates of ever undergoing Papanicolaou (Pap) testing at the intersection of self-reported sexual minority (SM) status and race/ethnicity.

METHODS

Data from the National Health Interview Survey (2015 and 2018) were used to examine cervical cancer screening disparities. Natal females without a history of hysterectomy who were 21 to 65 years old and had reported their sexual orientation and Pap testing history were included. Demographic and health characteristics were summarized with descriptive statistics. To adjust for differences in confounding variables between groups, propensity score-based inverse probability of treatment weighting (IPTW) was performed. IPTW-adjusted multivariable logistic regression models estimated odds of ever undergoing a Pap test by sexual orientation alone and with race/ethnicity (non-Hispanic White, non-Hispanic Black, and Hispanic).

RESULTS

SM persons (n = 877) had significantly reduced odds of ever undergoing Pap testing (odds ratio, 0.54; 95% confidence interval, 0.42-0.70) in comparison with heterosexual persons (n = 17,760). When the intersection of sexual orientation and race/ethnicity was considered, non-Hispanic White SM participants and Hispanic SM participants had reduced odds of ever undergoing Pap testing in comparison with non-Hispanic White heterosexual participants. No significant differences were observed between non-Hispanic White heterosexual participants and participants of non-Hispanic Black SM or Hispanic heterosexual identities.

CONCLUSIONS

SM participants were significantly less likely to have ever undergone a Pap test in comparison with heterosexual participants, with Hispanic SM participants having the lowest uptake. Future studies should further examine the roles of systemic discrimination and other key drivers of these disparities.

Human Papillomavirus Infection: Knowledge, Risk Perceptions and Behaviors among SMW and AFAB

Human papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) in the United States, and persistent HPV infection has been established as playing a major role in the development of cervical cancer. Providing HPV vaccination and regular screening tests have reduced the risk of developing cervical cancer or helped to detect the cancer at an early stage. Despite the above measures, cervical cancer still remains a major public health problem worldwide. Infection with HPV, and consequently cervical cancer, affects all people with an intact cervix, so not only heterosexual women, but also women from sexual minorities (SMW) together with people assigned female at birth (AFAB). These populations may be even more likely to develop cervical cancer, mainly because they are less likely to be aware of HPV transmission and prevention of cervical cancer. In our review, we summarized the current state of HPV knowledge, collected data assessing the orientation of this issue among SMW and AFAB, and indicated the causes of possible negligence in the prevention of cervical cancer.

Effects of the Affordable Care Act Dependent Coverage Mandate on Health Insurance Coverage for Individuals in Same-Sex Couples

A large body of research documents that the 2010 dependent coverage mandate of the U.S. Affordable Care Act was responsible for significantly increasing health insurance coverage among young adults. No prior research has examined whether sexual minority young adults also benefitted from the dependent coverage mandate despite previous studies showing lower health insurance coverage among sexual minorities. Our estimates from the American Community Survey, using difference-in-differences and event study models, show that men in same-sex couples aged 21-25 experienced a significantly greater increase in the likelihood of having any health insurance after 2010 than older, 27- to 31-year-old men in same-sex couples. This increase is concentrated among employer-sponsored insurance, and it is robust to permutations of periods and age groups. Effects for women in same-sex couples and men in different-sex couples are smaller than the associated effects for men in same-sex couples. These findings confirm the broad effects of expanded dependent coverage and suggest that eliminating the federal dependent mandate could reduce health insurance coverage among young adult sexual minorities in same-sex couples.

Contraceptive Care Disparities Among Sexual Orientation Identity and Racial/Ethnic Subgroups of U.S. Women: A National Probability Sample Study

Background: Sexual minority women may use contraception for various reasons but face notable barriers to contraceptive care, including stigma and discrimination. However, studies examining sexual orientation disparities in contraceptive care have largely relied on nonprobability samples of predominately White women and may thus not be generalizable to U.S. women overall or Black and Latina women in particular. Materials and Methods: Using data from the 2006 to 2017 National Survey of Family Growth, a large national probability sample of U.S. women 15-44 years of age (N = 25,473), we used multivariable logistic regression to estimate adjusted odds ratios for receiving a contraceptive method or prescription and contraceptive counseling from a health care provider in the past year among sexual orientation identity and racial/ethnic subgroups of heterosexual, bisexual, and lesbian White, Black, and Latina women relative to White heterosexual women. Results: Among women overall, 33.9% had received contraception and 18.3% had obtained contraceptive counseling. Black (odds ratio [OR] = 0.73, 95% confidence interval [CI]: 0.65-0.82) and Latina (OR = 0.73, 95% CI: 0.64-0.82) heterosexual women, White (OR = 0.80, 95% CI: 0.65-0.99) and Black (OR = 0.43, 95% CI: 0.32-0.58) bisexual women, and White (OR = 0.23, 95% CI: 0.13-0.43), Black (OR = 0.19, 95% CI: 0.09-0.40), and Latina (OR = 0.08, 95% CI: 0.03-0.22) lesbian women had significantly lower adjusted odds of receiving contraception compared with White heterosexual women. White (OR = 0.36, 95% CI: 0.15-0.85), Black (OR = 0.42, 95% CI: 0.18-0.98), and Latina (OR = 0.22, 95% CI: 0.09-0.53) lesbian women also had significantly lower adjusted odds of obtaining contraceptive counseling relative to White heterosexual women. Conclusions: Policies, programs, and practices that facilitate access to person-centered contraceptive care among marginalized sexual orientation identity and racial/ethnic subgroups of U.S. women are needed to promote reproductive health equity.

Sexual and reproductive health information: Disparities across sexual orientation groups in two cohorts of U.S. women

INTRODUCTION

Limited research exists about how receiving/seeking sexual and reproductive health (SRH) information differs by sexual orientation. Our goal was to identify how sources and topics of SRH information differed by sexual orientation during adolescence in a sample of U.S. women.

METHODS

A sample of 8,541 U.S. women ages 22-35 years from two cohorts of the Growing Up Today Study completed a 2016 questionnaire measure about receiving/seeking SRH information before age 18 years. Adjusted log-linear models assessed differences in SRH information topics and sources by reported sexual orientation (completely heterosexual with no same-sex partners [reference]; completely heterosexual with same-sex partners; mostly heterosexual; bisexual; lesbian).

RESULTS

Compared to the referent, most sexual minority subgroups were more likely to receive/seek information from peers, media, and other sources (e.g., community centers). With the exception of lesbians, sexual minority subgroups were more likely to receive/seek information about contraception, and mostly heterosexual and bisexual women were more likely to receive information about sexually transmitted infections. Conclusions: Findings indicate women of diverse sexual orientations need access to SRH information from sources like schools, peers, and media. Sexual minority women receive/seek information about many SRH topics, which indicates that opportunities to tailor educational resources within and outside of schools are needed so SRH benefits to these populations are maximized.

POLICY IMPLICATIONS

Specifying sexual minority-sensitive educational materials in sex education policy can meet information needs and aid sexual minority women in making informed sexual health decisions.

Sexual Behavior and Contraceptive Use Among Cisgender and Gender Minority College Students Who Were Assigned Female at Birth

STUDY OBJECTIVE

Our objective was to describe sexual behavior and contraceptive use among assigned female cisgender and gender minority college students (ie, those whose gender identity does not match their sex assigned at birth).

DESIGN

Cross-sectional surveys administered as part of the fall 2015 through spring 2018 administrations of the National College Health Assessment.

SETTING

Colleges across the United States.

PARTICIPANTS

A total of 185,289 cisgender and gender minority assigned females aged 18-25 years.

MAIN OUTCOME MEASURES

Recent vaginal intercourse; number and gender of sexual partners; use of contraception; use of protective barriers during vaginal intercourse.

RESULTS

Both gender minority and cisgender students often reported having male sexual partners, but gender minority students were more likely to report having partners of another gender identity (eg, women, trans women). Gender minorities were less likely than cisgender students to report having vaginal intercourse (adjusted odds ratio [AOR]: 0.86; 95% confidence interval [95% CI]: 0.80, 0.93). Gender minorities were less likely than cisgender students to report using any contraceptive methods (AOR: 0.86; 95% CI: 0.73, 1.03), and were less likely to consistently use barrier methods (AOR: 0.72; 95% CI: 0.64, 0.81) or emergency contraception (AOR: 0.56; 95% CI: 0.48, 0.65). However, gender minorities were more likely to use Tier 1 and Tier 3 contraceptive methods than cisgender women.

CONCLUSIONS

Providers must be trained to meet the contraceptive counseling needs of cisgender and gender minority patients. Providers should explicitly ask all patients about the sex/gender of the patients' sexual partners and the sexual behaviors in which they engage, to assess sexual risk and healthcare needs.

Differences in Tobacco Product Use by Sexual Orientation and Violence Factors Among United States Youth

OBJECTIVE

To assess differences in the relationship between violence factor exposure and tobacco product pattern use (exclusive and poly), we hypothesized that compared with heterosexuals, sexual minority youth would be more likely to report exclusive-tobacco and poly-tobacco use patterns, and controlling for violence factors would attenuate these associations.

STUDY DESIGN

Data from 27 513 US high-school youth were analyzed from the Centers for Disease Control and Prevention's Youth Risk Factor Surveillance System from 2015 and 2017. We fit sex-stratified, weighted, adjusted log-Poisson models to compare past 30-day exclusive combustible, exclusive e-cigarette, and poly-tobacco use in across sexual orientation. Then, models were adjusted for past-year experiences of physical fighting, bullying, attempting suicide, and physical and sexual dating violence.

RESULTS

Compared with heterosexual girls with other-sex partners, sexual minority girls were more likely to use exclusive combustible, exclusive e-cigarette, or poly-tobacco products. When adjusting for violence factors, most tobacco use associations were partially attenuated for all sexual minority girls, and completely attenuated for exclusive e-cigarette use among all sexual minority girls.

CONCLUSIONS

Sexual minority girls have greater exclusive- and poly-tobacco use compared with heterosexual girls. Tobacco interventions for sexual minority youth should address the risks of poly-tobacco use as well as violence-based risk factors.

Variation in diet quality across sexual orientation in a cohort of U.S. women

PURPOSE

Extensive prior research has shown that sexual minority women are more likely to have a number of cancer risk factors, thereby putting them at higher risk for cancer than heterosexual women. However, there has been little research evaluating the association between sexual orientation and diet quality.

METHOD

Data come from participants (aged 24-54 years) enrolled in Nurses' Health Study 3, an ongoing, U.S.-based cohort study (N = 15,941). We measured diet using recommendations from the Dietary Approach to Stop Hypertension (DASH) and American Health Association (AHA) 2020 Strategic Impact Goals.

RESULTS

We found limited evidence of differences across diet quality by sexual orientation. When examining predicted DASH scores, mostly heterosexual [predicted mean score (95% confidence interval), 24.0 (23.8, 24.3)] and lesbian [24.3 (23.8, 24.9)] women had healthier predicted DASH scores than the reference group of completely heterosexual women with no same-sex partners [23.6 (23.5, 23.7)]. Even though certain sexual minority women had overall healthier predict DASH scores, their consumption of certain food groups-low-fat dairy and fruit-was lower than completely heterosexual women with no same-sex partners. When measuring AHA scores, most sexual minority groups (completely heterosexual women with same-sex partners, mostly heterosexual women, and lesbian women) had higher diet quality compared to the reference group of completely heterosexual women with no same-sex partners.

CONCLUSION

Sexual minority women, particularly mostly heterosexual women and lesbian women, had healthier diet quality than completely heterosexual women with no same-sex partners. These data suggest that cancer risk factors (e.g., smoking, drinking, and inactivity) other than diet would drive higher cancer rates among sexual minority compared to heterosexual women. Nonetheless, it is critical for all women to improve their diet quality since diet quality was poor among participants of all sexual orientations.

Sexual orientation-related differences in contraceptive use: A brief report based on a cohort of adolescent and young women

OBJECTIVES

To examine contraceptive methods used by adolescent/young adult women of diverse sexual orientations.

STUDY DESIGN

We collected data from 12,902 females, born 1982-1995, from the longitudinal Growing Up Today Study.

RESULTS

Compared to heterosexuals, lesbians were half as likely to use contraceptives; other sexual minority subgroups (e.g., bisexuals) were more likely to use contraceptives, particularly long-acting reversible contraceptives.

CONCLUSIONS

Many sexual minority women use contraception throughout adolescence/young adulthood, though use is low among lesbians.

IMPLICATIONS

With limited contraception use, lesbians miss opportunities for care and need to be brought into the healthcare system in other ways.

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.

Sexual Minority Women's Sexual and Reproductive Health Literacy: A Qualitative Descriptive Study

Although sexual minority women (SMW) are at risk for cervical cancer and sexually transmitted infections (STIs), they may not seek preventative sexual and reproductive health care at the same rates as their heterosexual peers. We conducted a qualitative descriptive study of 22 adult SMW, a subsample of participants enrolled in the Chicago Health and Life Experiences of Women study. The aim was to describe the sexual and reproductive health literacy of this community sample based on qualitative themes, using an integrated model of health literacy. This model considers not only access to information but also understanding, appraisal, and application of information. We found that family of origin, health care providers, and school-based sexual education were the most important sources of sexual and reproductive health information. Participants described their understanding, appraisal, and application of sexual and reproductive health information as interdependent concepts. Pap test literacy and decision making were strongly independent, with SMW seeking various sources of information, or were driven by health care providers, with SMW following instructions and trusting provider advice. STI-related literacy hinged on whether the participant perceived SMW as at risk for STIs. Our findings reinforce that simply having access to information is insufficient to enact health behaviors that reflect full literacy. Findings have implications for health care providers, who should provide evidence-based recommendations for their SMW clients, and for public health practitioners and educators, who could make sexual health education more inclusive of and specific to the needs of SMW.

Racial/Ethnic Differences in Unwanted Pregnancy: Moderation by Sexual Orientation

OBJECTIVE

To explore sexual orientation disparities in unwanted pregnancy by race/ethnicity.

BACKGROUND

Previous research has documented that sexual-minority women (SMW) are more likely to report unplanned pregnancy than heterosexual women, and that Black and Latina women are more likely to report unplanned pregnancy than White women. No research has examined how pregnancy intention varies at the intersection of these two identities.

METHOD

Data come from the pregnancy roster data in Waves IV and Wave V subsample in the National Longitudinal Study of Adolescent to Adult Health. We used pregnancy as the unit of analysis (n=10,845) and multilevel logistic regression models to account for clustering of pregnancies within women. Per pregnancy, women were asked if they "wanted" to be pregnant at the time of pregnancy. We conducted models stratified by race/ethnicity, as well as models stratified by sexual identity.

RESULTS

Among White women, sexual-minority women were more likely to describe their pregnancy as unwanted than were their heterosexual counterparts. Conversely, among Black and Latina women, sexual-minority women were less likely to describe their pregnancy as unwanted than were their heterosexual counterparts. Results stratified by sexual identity underscore these contrasting patterns: Among heterosexual women, White women were less likely to describe their pregnancies as unwanted compared to Black and Latina women; among sexual-minority women, White women were more likely to describe their pregnancy as unwanted than were Black and Latina women.

CONCLUSION

Traditional race/ethnicity trends in pregnancy intention (i.e., greater unwanted pregnancy among Black/Latina than White women) are reversed among sexual-minority women.

Sexual Orientation Differences in Cervical Cancer Prevention among a Cohort of U.S. Women

BACKGROUND

Although much has been published in recent years on differences in Papanicolaou (Pap) tests across sexual orientation, other aspects of cervical cancer prevention remain underexplored, such as human papillomavirus (HPV) vaccination, HPV co-tests, or abnormal Pap tests.

METHODS

Data came from participants (aged 24-54 years) enrolled in an ongoing, longitudinal, U.S.-based cohort study, the Nurses' Health Study 3 (N = 12,175). Analyses were restricted to participants who met the current guidelines for care (e.g., ≥21 years of age for Pap tests).

RESULTS

Mostly heterosexual women were more likely to initiate HPV vaccination than completely heterosexual women with no same-sex partners. All other comparisons across sexual orientation for HPV vaccination initiation and completion and the age of initiation were not statistically significant. Compared with completely heterosexual women with no same-sex partners, mostly heterosexual and lesbian women had lower odds of having a Pap test within the past 2 years. Completely heterosexual women with same-sex partners, mostly heterosexual women, and bisexual women had their first Pap test at an earlier age, had higher odds of having an HPV co-test, and had higher odds of having a positive HPV or abnormal Pap test compared with completely heterosexual women with no same-sex partners. In contrast, lesbian women had lower odds of having positive HPV or abnormal Pap results (odds ratio, 0.65; 95% confidence interval, 0.49-0.86) than completely heterosexual women with no same-sex partners.

CONCLUSIONS

There are significant differences across sexual orientation groups in cervical cancer prevention for Pap test timing and positive HPV and abnormal Pap tests, but few differences in HPV vaccination initiation, completion, and age at initiation. Interventions should focus on increasing routine Pap testing among mostly heterosexual and lesbian women.

Dimensions of Sexual Orientation as Predictors of STI-Related Outcomes Among Women: An Examination of 2011-2017 National Survey of Family Growth Data

Background: To estimate sexual orientation associated disparities in sexually transmitted infection (STI)-related outcomes across multiple dimensions of sexual orientation. Methods: Using pooled 2011-2017 National Survey of Family Growth data (N = 16,854), we performed bivariate and multivariable logistic and multinomial regression analyses to estimate associations between sexual identity, behavior in the past 12 months, and attraction, and past-year STI treatment, receipt of the human papillomavirus (HPV) vaccine, and age at first HPV vaccination in cisgender women. Results: Bisexual-identified women (adjusted odds ratio [AOR] = 1.53, 95% confidence interval [CI] = 1.10-2.14) and who were sexually active with both men and women in the past 12 months (AOR = 1.64, 95% CI = 1.03-2.55) had significantly higher odds of past-year STI treatment, compared with their nonsexual minority counterparts. Lesbian-identified women (AOR = 0.44, 95% CI = 0.27-0.75) and women with female partners only (AOR = 0.32, 95% CI = 0.12-0.87) had significantly decreased odds of having initiated the HPV vaccine compared with their heterosexual counterparts. Women with both male and female partners who initiated the HPV vaccine had significantly higher odds of having received the vaccine during the latest age range, 18-25 years old (AOR = 2.32, 95% CI = 1.21-4.45) compared with women with male partners only. Conclusions: Sexual minority women continue to be at risk for poor sexual health outcomes, and these outcomes differ by specific components of sexual orientation.

Sexual orientation inequalities during provider-patient interactions in provider encouragement of sexual and reproductive health care

The human papillomavirus (HPV) vaccination, sexually transmitted infection (STI) tests, and Papanicolaou (Pap) testing rates vary by sexual orientation, which may be due in part to healthcare providers (HCP) recommending this care unevenly. Data (N = 17,675) came from the Growing Up Today Study (GUTS) (N = 8039) and Nurses' Health Study 3 (NHS3) (N = 9636). Among participants who met clinical guidelines to receive the care in question, we estimated the probability of an HCP encouraging participants to have the HPV vaccination, STI tests, or Pap test. Regardless of sexual orientation, participants whose HCP knew their sexual orientation were more likely to have been encouraged to get care compared to those whose HCP did not know the participant's sexual orientation. Sexual minority men and women were more likely to be encouraged to obtain HPV vaccination, STI tests, and Pap test than same-gender, completely heterosexuals with no same-sex partners, with some variation by gender and the care in question. Lesbian women were the sole sexual orientation subgroup that was less likely to be encouraged to receive care (HPV vaccination and Pap test) than their same gender, completely heterosexual counterparts with no same-sex partners (odds ratio [95% confidence interval]: 0.90 [0.80-1.00] and 0.94 [0.91-0.98], respectively). The differences across sexual orientation in HCPs' encouragement of care indicate a possible explanation for differences in utilization across sexual orientation. Across the US, HCPs under-encourage HPV vaccination, STI tests, and Pap test for all sexual orientation groups. Lesbian patients appear to be at high risk of under-encouragement for the Pap test.

Contraceptive use by women across different sexual orientation groups

OBJECTIVES

To examine contraceptive methods used across sexual orientation groups.

STUDY DESIGN

We collected data from 118,462 female participants in two longitudinal cohorts-the Nurses' Health Study (NHS) 2 (founded in 1989, participants born 1947-1964) and NHS3 (founded in 2010, born 1965-1995). We used log-binomial models to estimate contraceptive methods ever used across sexual orientation groups and cohorts, adjusting for age and race.

RESULTS

Lesbians were the least likely of all sexual orientation groups to use any contraceptive method. Lesbians in NHS2 were 90% less likely than heterosexuals to use long-acting reversible contraceptives (LARCs; adjusted risk ratio [aRR]; 95% confidence interval [CI]: 0.10 [0.04, 0.26]) and results were similar for other contraceptive methods and in the NHS3 cohort. Compared to the reference group of completely heterosexual participants with no same-sex partners, those who identified as completely heterosexual with same-sex partners, mostly heterosexual, or bisexual were generally more likely to use any method of contraception. Use of LARCs was especially striking across sexual minority groups, and, with the exception of lesbians, they were more likely to use LARCs; as one illustration, NHS3 bisexuals were more than twice as likely to use LARCs (aRR [95% CI]: 2.01 [1.67, 2.42]).

CONCLUSIONS

While certain sexual minority subgroups (e.g., bisexuals) were more likely than heterosexuals to use contraceptive methods such as LARCs, lesbians were less likely to use any method.

IMPLICATIONS

Many sexual minority patients need contraceptive counseling and providers should ensure to offer this counseling to patients in need, regardless of sexual orientation.

Maternal Factors and Sexual Orientation-Related Disparities in Cervical Cancer Prevention

OBJECTIVES

Our objective was to explore how mothers' attitudes and relationships with their daughters may impact the cervical cancer prevention behaviors of daughters with diverse sexual orientations.

METHODS

We examined 8,143 mother-daughter dyads from the Nurses' Health Study 2 and Growing Up Today Study. During the daughter's adolescence, each mother reported her beliefs about the importance of regular Pap testing for her daughter, the frequency of communication with her daughter about Pap testing, her beliefs about Pap testing and human papillomavirus (HPV) vaccines, and her acceptance of sexual minorities (e.g., bisexuals, lesbians). Mothers and daughters separately reported relationship satisfaction. Log-binomial models were used to examine the longitudinal association between maternal factors and daughter's receipt of a Pap test and HPV vaccination.

RESULTS

Nearly all maternal factors predicted the daughter's likelihood to have a Pap test and HPV vaccination. Higher levels of acceptance for sexual minorities and better relationship quality were also positively associated with these cervical cancer prevention behaviors. Yet, after adjusting for the maternal factors, there was little attenuation of the existing sexual orientation-related disparities in Pap tests or HPV vaccination.

CONCLUSIONS

Mothers can play an important role in their daughters' cervical cancer prevention behaviors through novel processes like being more accepting of sexual minorities and having a good relationship quality. However, in this study, maternal factors did not explain much of the sexual orientation-related disparities in cervical cancer prevention. Efforts to ensure a mother is accepting of sexual minorities and has a good relationship quality with her daughter may improve that daughter's reproductive health.

Predicting cervical cancer screening among sexual minority women using Classification and Regression Tree analysis

Cervical cancer screening is a critical preventive healthcare service for all women. Sexual minority women (SMW) in the United States experience multiple health disparities including decreased access to and use of cervical cancer screening. The mechanisms driving these disparities are not clear and SMW with multiple marginalized identities may be more likely to miss recommended cervical cancer screening. This study aimed to identify subgroups of SMW that are more and less likely to be screened for cervical cancer according to American Cancer Society guidelines. We used cross-sectional data from the latest (2010-2012) wave of the Chicago Health and Life Experiences of Women (CHLEW) Study (N = 691). Informed by intersectionality theory, we performed classification and regression tree (CART) modeling to construct a data-driven, predictive model of subgroups of SMW who were more and less likely to receive guideline-recommended screening. Notably, the CART model did not include commonly tested variables such as race/ethnicity or level of income or education. The model did identify subgroups with low likelihood of receiving screening and several novel variables that may be important in understanding SMW's use of cervical cancer screening; lifetime number of sexual partners, age at drinking onset, childhood physical abuse, and internalized homonegativity. Our results point to the importance of early life experiences and identity development processes in shaping patterns of preventive healthcare use among adult SMW. Our analysis also demonstrated the potential value of CART modeling techniques for evaluating how multiple variables interact in complex ways to predict cervical cancer screening.

Sexual Orientation and Pregnancy Among Adolescent Women in the National Survey of Family Growth, 2002-2015

Purpose: Given elevated pregnancy rates, fluctuating sexual identity, and varying sexual experience among adolescent sexual minority women (ASMW; lesbian/bisexual identity, attraction to/sex with females), research should assess adolescent pregnancy by sexual attraction with identity and experience. This study examined associations of three aspects of sexuality-identity, attraction, and experience-with pregnancy among ASMW versus non-ASMW. Methods: Population-weighted data were drawn from the 2002 to 2015 National Survey of Family Growth (NSFG), 15- to 19-year-old female subsample (n = 5481). Multivariable logistic regression models (adjusted for age, race/ethnicity, and survey cycle) compared pregnancy among ASMW versus non-ASMW by sexual identity, attraction, and experience separately, and in a combined model in which interaction of aspects of sexuality and survey cycle was tested. The combined model was then stratified by survey cycle. Results: Although not significant in the combined model, sexual minority versus heterosexual identity (adjusted odds ratio [aOR] = 1.74, 95% confidence interval [CI] = 1.21-2.51, p = 0.003) and sexual minority versus exclusive male attraction (aOR = 1.49, 95% CI = 1.10-2.01, p = 0.011) individually predicted higher pregnancy odds. There was significant interaction between attraction and survey cycles. Sexual minority attraction predicted significantly decreased pregnancy odds (aOR = 0.59, 95% CI = 0.38-0.90, p = 0.014) in combined 2002 to mid-September 2013 NSFG data, but increased odds (aOR = 1.59, 95% CI = 0.63-4.02, p = 0.324) in the rest of 2013-2015. Conclusion: These results suggest the importance of measuring sexual attraction when examining pregnancy disparities among ASMW. Sex education and teen pregnancy prevention programs should reflect sexual diversity.

Do Sexual Minorities Receive Appropriate Sexual and Reproductive Health Care and Counseling?

CONTEXT

Sexual minority women (SMW) are less likely to use sexual and reproductive health care services and receive contraceptive counseling than their heterosexual peers. The role of recent sexual partners and the type of information provided when SMW access health services are unclear.

METHODS

The National Survey of Family Growth 2006-2015 was used to document sexual orientation disparities in the use of sexual and reproductive health services and counseling in clinical settings among 20,703 women. We incorporate data on sexual partners in the past 12 months to investigate whether recent sex with men was associated with health care seeking behavior and reproductive counseling.

RESULTS

Eight-seven percent of the sample reported a male partner in the past 12 months, including 83% of bisexual women and 17% of lesbian women. In clinical settings, 48% of women reported birth control counseling at pregnancy or Pap tests, 49% reported a condom consult at an sexually transmitted diseases (STD) screening, and 9% reported emergency contraception counseling at a Pap test. Logistic regression models show that lesbian women were less likely than heterosexual women to have been given a contraceptive prescription or received contraceptive counseling, but were more likely to have received an STD test. In clinical settings, lesbian women were less likely to receive contraceptive counseling at pregnancy tests, and lesbian women without male partners were less likely to have a counseling about condom use at STD-related visits compared with heterosexual women.

CONCLUSIONS

At least some women and providers adjust health care seeking behaviors and information provided to women based upon recent sexual behavior histories. More work is needed to understand why disparities in reproductive health services and contraceptive use persist among SMW who engage in sex with men.

Health Care-Related Correlates of Cervical Cancer Screening among Sexual Minority Women: An Integrative Review

INTRODUCTION

Sexual minority women (SMW; lesbian, bisexual, nonheterosexual women) may have lower rates of cervical cancer screening than heterosexual women. Health care-related factors may explain some of the variation in cervical cancer screening rates among SMW. We aimed to synthesize published evidence of health care-related correlates of cervical cancer screening among SMW.

METHODS

We searched PubMed, CINAHL, and PsycINFO databases for English-language studies published between January 2000 and March 2017 that 1) assessed sexual identity or the sexual partners of female participants, 2) included cervical cancer screening as a main outcome of interest, and 3) measured at least one health care-related variable in addition to cervical cancer screening. We excluded articles that 1) reported on non-US samples or 2) did not report original research. We reviewed the sample, methods, and findings of 17 studies. We then summarized current knowledge about health care-related factors across 3 categories and generated recommendations for clinical practice and future research.

RESULTS

Several health care-related factors such as previous contraception use, having a primary care provider, knowledge of screening recommendations, and disclosing sexual orientation to providers were consistently positively associated with cervical cancer screening. Three groups of factors-previous health care use, health care provider-related factors, and belief-related factors-account for a substantial part of the variation in cervical cancer screening among SMW.

DISCUSSION

Several gaps in knowledge remain that could be addressed by recruiting more diverse samples of SMW with improved generalizability. Clinicians and clinical institutions can address factors associated with low rates of screening among SMW by preventing sexual orientation-based discrimination, inviting sexual orientation disclosure, and offering cervical cancer screening to SMW at a variety of health care encounters. Future research should examine how the location of care and health care provider type affect SMW's cervical cancer screening behaviors and should test the effectiveness of health care interventions designed to address sexual orientation-related disparities.

Association of Pregnancy History and Cervical Cancer Screening in a Community Sample of Sexual Minority Women

BACKGROUND

Sexual minority women (SMW) face barriers to healthcare that may result in lower utilization of cervical cancer screening. Previous experiences with the healthcare system-specifically reproductive health-related encounters-have the potential to affect future use of screening services. This study aimed to examine the association between pregnancy history and cervical cancer screening in a diverse sample of SMW. Anderson's Behavioral Model of Health Services Use guided the selection of variables included in the study.

METHODS

We performed a secondary analysis of cross-sectional data from the third wave of the Chicago Health and Life Experiences of Women (CHLEW) Study, a longitudinal study of SMW in the Midwestern United States. We performed multivariable logistic regression to address the study aims, restricting the sample to women ages 21-45 (n = 430).

RESULTS

Reporting a previous pregnancy was consistently positively associated with past-year Pap testing. In the multivariable model, bisexual identity and disclosing one's sexual orientation to healthcare providers were also positively associated with past-year Pap test.

CONCLUSIONS

This analysis provides preliminary evidence that SMW who have been pregnant are more likely to receive Pap testing and that multiple sociodemographic factors are likely to impact screening in this population. Clinicians should screen all patients with a cervix for cervical cancer and should encourage screening for all SMW. Future studies should prioritize longitudinal analyses to examine the temporality of reproductive history and healthcare seeking, focus on where SMW seek care, and understand how intersecting components of identity may shape the healthcare utilization of this population.

Sexual Health Care Services among Young Adult Sexual Minority Women

Young adult sexual minority women (YSMW) are at elevated risk for negative reproductive health outcomes, yet are less likely than heterosexual peers to utilize preventive health care. Medical and public health policy organizations advocate sexual orientation disclosure ("coming out") to health care providers as a strategy for increasing service utilization among YSMW. Limited research explores relationships between disclosure and receipt of sexual health services. YSMW (N=285) ages 21-24 participated in an online survey assessing their health behaviors and care utilization. We employed multivariable logistic regression models to examine the association between receipt of sexual health services and sexual orientation disclosure to provider, after adjusting for sociodemographic covariates. Thirty-five percent of YSMW were out to their provider. Less than half the sample had received Pap screening or STI testing in the previous year; approximately 15% had received at least one dose of the HPV vaccination. Disclosure was associated with increased likelihood of Pap screening (OR=2.66, p<.001) and HPV vaccination (OR=4.30, p<.001), but was not significantly associated with STI testing. Promoting coming out to providers may be a promising approach to increase sexual health care use among YSMW. Future research should explore causal relationships between these factors.

Sexual Orientation Disparities in Human Papillomavirus Vaccination in a Longitudinal Cohort of U.S. Males and Females

PURPOSE

This study sought to examine how human papillomavirus (HPV) vaccination may differ across sexual orientation groups (e.g., bisexuals compared to heterosexuals)-particularly in boys and men, about whom little is known.

METHODS

Data were from a prospective cohort of 10,663 U.S. females and males enrolled in the Growing Up Today Study followed from 1996 to 2014. Participants were aged 11-24 years when the vaccine was approved for females in 2006 and 14-27 years when approved for males in 2009. In addition to reporting sexual orientation identity/attractions, participants reported sex of lifetime sexual partners. Log-binominal models were used to examine HPV vaccination across sexual orientation groups.

RESULTS

Among females, 56% received ≥1 dose. In contrast, 8% of males obtained ≥1 dose; HPV vaccination initiation was especially low among completely heterosexual males. After adjusting for potential confounders, completely heterosexual (risk ratio [RR]; 95% confidence interval [CI]: 0.45 [0.30-0.68]) and mostly heterosexual (RR; 95% CI: 0.44 [0.25-0.78]) males were half as likely to have received even a single dose compared to gay males. Compared to lesbians, no differences were observed for completely heterosexual or bisexual females, but mostly heterosexual females were 20% more likely to have received at least one dose.

CONCLUSIONS

HPV vaccination rates in the U.S. are strikingly low and special attention is needed for boys and men, especially those who do not identify as gay. Vaccinating everyone, regardless of sex/gender and/or sexual orientation, will not only lower that individual's susceptibility but also decrease transmission to partners, females and/or males, to help eradicate HPV through herd immunity.

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.

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.

At the intersection of sexual orientation, race/ethnicity, and cervical cancer screening: assessing Pap test use disparities by sex of sexual partners among black, Latina, and white U.S. women

Understanding how various dimensions of social inequality shape the health of individuals and populations poses a key challenge for public health. Guided by ecosocial theory and intersectionality, we used data from the 2006-2010 National Survey of Family Growth, a national probability sample, to investigate how one dimension of sexual orientation, sex of sexual partners, and race/ethnicity jointly influence Pap test use among black, Latina and white U.S. women aged 21-44 years (N = 8840). We tested for an interaction between sex of sexual partners and race/ethnicity (p = 0.015) and estimated multivariable logistic regression models for each racial/ethnic group, adjusting for socio-demographic factors. The adjusted odds of Pap test use for women with only female sexual partners in the past year were significantly lower than for women with only male sexual partners in the past year among white women (odds ratio [OR] = 0.25, 95% confidence interval [CI]: 0.12,0.52) and may be lower among black women (OR = 0.32, 95% CI: 0.07,1.52); no difference was apparent among Latina women (OR = 1.54, 95% CI: 0.31,7.73). Further, the adjusted odds of Pap test use for women with no sexual partners in the past year were significantly lower than for women with only male sexual partners in the past year among white (OR = 0.30, 95% CI: 0.22,0.41) and black (OR = 0.23, 95% CI: 0.15,0.37) women and marginally lower among Latina women (OR = 0.63, 95% CI: 0.38,1.03). Adding health care indicators to the models completely explained Pap test use disparities for women with only female vs. only male sexual partners among white women and for women with no vs. only male sexual partners among Latina women. Ecosocial theory and intersectionality can be used in tandem to conceptually and operationally elucidate previously unanalyzed health disparities by multiple dimensions of social inequality.
