Sexual Orientation-Related Disparities in Neonatal Outcomes.

OBJECTIVE: To evaluate whether disparities exist in adverse neonatal outcomes among the offspring of lesbian, gay, bisexual, and other sexually minoritized (LGB+) birthing people. METHODS: We used longitudinal data from 1995 to 2017 from the Nurses' Health Study II, a cohort of nurses across the United States. We restricted analyses to those who reported live births (N=70,642) in the 2001 or 2009 lifetime pregnancy questionnaires. Participants were asked about sexual orientation identity (current and past) and same-sex attractions and partners. We examined preterm birth, low birth weight, and macrosomia among 1) completely heterosexual; 2) heterosexual with past same-sex attractions, partners, or identity; 3) mostly heterosexual; 4) bisexual; and 5) lesbian or gay participants. We used log-binomial models to estimate risk ratios for each outcome and weighted generalized estimating equations to account for multiple pregnancies per person over time and informative cluster sizes. RESULTS: Compared with completely heterosexual participants, offspring born to parents in all LGB+ groups combined (groups 2-5) had higher estimated risks of preterm birth (risk ratio 1.22, 95% CI, 1.15-1.30) and low birth weight (1.27, 95% CI, 1.15-1.40) but not macrosomia (0.98, 95% CI, 0.94-1.02). In the subgroup analysis, risk ratios were statistically significant for heterosexual participants with past same-sex attractions, partners, or identity (preterm birth 1.25, 95% CI, 1.13-1.37; low birth weight 1.32, 95% CI, 1.18-1.47). Risk ratios were elevated but not statistically significant for lesbian or gay participants (preterm birth 1.37, 95% CI, 0.98-1.93; low birth weight 1.46, 95% CI, 0.96-2.21) and bisexual participants (preterm birth 1.29, 95% CI, 0.85-1.93; low birth weight 1.24, 95% CI, 0.74-2.08). CONCLUSION: The offspring of LGB+ birthing people experience adverse neonatal outcomes, specifically preterm birth and low birth weight. These findings highlight the need to better understand health risks, social inequities, and health care experiences that drive these adverse outcomes.

Mapping the scientific literature on obstetric and perinatal health among sexual and gender minoritized (SGM) childbearing people and their infants: a scoping review.

BACKGROUND: Evidence suggests sexual and gender minoritized (SGM) childbearing individuals and their infants experience more adverse obstetric and perinatal outcomes compared to their cisgender, heterosexual counterparts. This study aimed to comprehensively map obstetric and perinatal physical health literature among SGM populations and their infants and identify knowledge gaps. METHODS: PubMed, Embase, CINAHL, and Web of Science Core Collection were systematically searched to identify published studies reporting obstetric and perinatal outcomes in SGM individuals or their infants. Study characteristics, sample characteristics, and outcome findings were systematically extracted and analyzed. RESULTS: Our search yielded 8,740 records; 55 studies (1981-2023) were included. Sexual orientation was measured by self-identification (72%), behavior (55%), and attraction (9%). Only one study captured all three dimensions. Inconsistent measures of sexual orientation and gender identity (SOGI) were common, and 68% conflated sex and gender. Most (85%) focused on sexual minorities, while 31% addressed gender minorities. Demographic measures employed varied widely and were inconsistent; 35% lacked race/ethnicity data, and 44% lacked socioeconomic data. Most studies (78%) examined outcomes among SGM individuals, primarily focusing on morbidity and pregnancy outcomes. Pregnancy termination was most frequently studied, while pregnancy and childbirth complications (e.g., gestational hypertension, postpartum hemorrhage) were rarely examined. Evidence of disparities were mixed. Infant outcomes were investigated in 60% of the studies, focusing on preterm birth and low birthweight. Disparities were noted among different sexual orientation and racial/ethnic groups. Qualitative insights highlighted how stigma and discriminatory care settings can lead to adverse pregnancy and birth outcomes. CONCLUSIONS: Frequent conflation of sex and gender and a lack of standardized SOGI measures hinder the comparison and synthesis of existing evidence. Nuanced sociodemographic data should be collected to understand the implications of intersecting identities. Findings on perinatal health disparities were mixed, highlighting the need for standardized SOGI measures and comprehensive sociodemographic data. The impact of stigma and discriminatory care on adverse outcomes underscores the need for inclusive healthcare environments. Future research should address these gaps; research on SGM perinatal outcomes remains urgently lacking. TRIAL REGISTRATION: The review protocol was developed a priori in February 2023, registered on Open Science Framework ( https://doi.org/10.17605/OSF.IO/5DQV4 ) and published in BMJ Open ( https://bmjopen.bmj.com/content/13/11/e075443 ).

Perspectives of Sexual and Gender Minority Youth on Anti-Vaping Messages in Social Media.

INTRODUCTION: Sexual and gender minority (SGM) youth have higher rates of nicotine vaping than other youth in the United States. While social media can be effective in reaching youth and discouraging vaping, informed cultural tailoring is necessary to ensure effective messaging to SGM youth. This study aimed to understand SGM youth perspectives on anti-vaping social media messages and tailoring approaches. METHODS: In-depth, qualitative videoconference interviews were conducted from February to July 2022 with 34 SGM youth recruited in the United States via social media ads. The interview guide addressed participants' beliefs about vaping, the context of vaping, perspectives on tailoring messages, and responses to examples of social media anti-vaping messages. Coding and thematic analysis followed a team-based approach. RESULTS: SGM youth perspectives fell into four categories - representation and diversity, facts and evidence, empowering messages, and source credibility. Participants stressed the importance of accurate, genuine representation of SGM youth in messages, but also noted that more overt representation may be seen as tokenizing. Participants recommended partnering with known LGBTQ+ influencers who can promote or share anti-vaping messages on social media platforms. They also recommended using culturally tailored language, including statistics specific to SGM youth, and invoking themes of empowerment to improve the relevance, reach, and effectiveness of anti-vaping campaigns. CONCLUSIONS: Findings can inform future efforts to develop anti-vaping messages for SGM youth with effective reach through social media. Nuanced perspectives on SGM representation in messages suggest a careful approach to tailoring. Concerns around inauthenticity may be minimized by ensuring SGM youth are included in message development and dissemination. IMPLICATIONS: This study describes the importance of being attentive to the tailoring preferences among the current generation of sexual and gender minority youth. Findings will inform social media-based messaging strategies that discourage nicotine vaping tailored for SGM youth in health campaign material design and evaluation, ensuring that tailored messages are designed in ways that avoid unintended consequences. The study also describes methods for effectively engaging SGM youth in research to improve the relevance of health education materials for this population and increase reach, which in turn can lead to reduction in vaping practices among SGM youth.

Effective and inclusive mentorship in the field of epidemiology.

Quality mentoring improves outcomes across career stages, including a sense of belonging, persistence, and productivity. However, the status quo in mentorship culture-including in epidemiology-is an ad hoc approach. This pervasive culture adversely affects individual mentees and the entire scientific research enterprise. Public health disciplines such as epidemiology bear a distinct responsibility to foster an inclusive mentorship culture, ensuring the next generation is equipped not only with methodological expertise but also with a commitment to diversity, equity, inclusion, and the principles of public health. In this commentary, we outline the primary attributes of effective mentors, core competencies, and the evidence base underlying how mentors can improve their skills with comprehensive training. We call on mentors, as well as institutional leaders, to make personal and structural changes, such as requiring mentor training, implementing evidence-based tools (e.g., individual development plans), and regularly evaluating mentorship quality. Institutional leaders can remove barriers (e.g., costs to enroll in mentor training) and facilitate mentorship in non-monetary ways, for example, by making it a formal part of the promotion process. Mentors and leaders must champion these changes, fortifying not only individual career trajectories but also advancing scientific integrity, inclusivity, and justice within the epidemiologic community.

Sexual Orientation-Specific Policies Are Associated With Prenatal Care Use in the First Trimester Among Sexual Minority Women: Results From a Prospective Cohort Study.

BACKGROUND: Previous research has shown sexual minority women (SMW) are more likely to report multiple maternal and infant health outcomes compared to heterosexual women and that these outcomes are moderated by the policy environment. Little is known, however, about prenatal care use disparities or the social determinants of prenatal care use for SMW. PURPOSE: To examine the relationship between sexual orientation-specific policies that confer legal protections (e.g., hate crime protections, housing discrimination, same-sex marriage) and prenatal care use among women using a prospective, population-based data set. METHODS: Using the National Longitudinal Study of Adolescent to Adult Health and logistic regression, we link measures of state policies to the use of prenatal care in the first trimester among women who had live births. The use of prospective data allows us to adjust for covariates associated with preconception care use prior to pregnancy (n = 586 singleton births to SMW; n = 4,539 singleton births to heterosexual women). RESULTS: Sexual orientation-specific policies that conferred protections were associated with increased use of prenatal care among pregnancies reported by SMW (OR = 1.86, 95% CI 1.16, 2.96). In fact, in states with zero protections, we found no differences in prenatal care use by sexual minority status; however, in states with two or more protective policies, SMW were more likely to access prenatal care in the first trimester than heterosexual women. There was no relationship between sexual orientation-specific policy environments and prenatal care use among pregnancies reported by heterosexual women. CONCLUSIONS: Recent research has documented that SMW are more likely to have adverse perinatal and obstetrical outcomes than their heterosexual peers. These findings suggest that Lesbian/Gay/Bisexual-specific policy protections may facilitate the use of prenatal care among SMW, a potentially important pathway to improve reproductive health among this population.

Previous studies have found that sexual minority women (SMW) are more likely to report adverse infant outcomes, particularly for women who do not live in states with anti-discrimination policies against lesiban, gay, bisexual, transgnder, or queer (LGBTQ) populations. This is the first to examine sexual orientation disparities in prenatal care use using a nationally representative, prospective data set. Additionally, we examined whether prenatal care use varied by the number of state-level policies that protect against discrimination based on sexual orientation. Our results show high rates of prenatal care use in the first trimester across all sexual orientations, however, in states with states with two or more policies that prevent discrimination by sexual orientation, sexual minority women were more likely to access prenatal care in the first trimester than heterosexual women. These findings suggest that more inclusive state-level environments promote healthcare-seeking behaviors during pregnancy for sexual minority women.

Sexual orientation disparities in gestational diabetes and hypertensive disorders of pregnancy.

BACKGROUND: Sexual minority (SM) individuals (e.g., those with same-sex attractions/partners or who identify as lesbian/gay/bisexual) experience a host of physical and mental health disparities. However, little is known about sexual orientation-related disparities in gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP; gestational hypertension [gHTN] and preeclampsia). OBJECTIVE: To estimate disparities in GDM, gHTN and preeclampsia by sexual orientation. METHODS: We used data from the Nurses' Health Study II-a cohort of nurses across the US enrolled in 1989 at 25-42 years of age-restricted to those with pregnancies ≥20 weeks gestation and non-missing sexual orientation data (63,518 participants; 146,079 pregnancies). Our primary outcomes were GDM, gHTN and preeclampsia, which participants reported for each of their pregnancies. Participants also reported their sexual orientation identity and same-sex attractions/partners. We compared the risk of each outcome in pregnancies among heterosexual participants with no same-sex experience (reference) to those among SM participants overall and within subgroups: (1) heterosexual with same-sex experience, (2) mostly heterosexual, (3) bisexual and (4) lesbian/gay participants. We used modified Poisson models to estimate risk ratios (RR) and 95% confidence intervals (CI), fit via weighted generalised estimating equations, to account for multiple pregnancies per person over time and informative cluster sizes. RESULTS: The overall prevalence of each outcome was ≤5%. Mostly heterosexual participants had a 31% higher risk of gHTN (RR 1.31, 95% CI 1.03, 1.66), and heterosexual participants with same-sex experience had a 31% higher risk of GDM (RR 1.31, 95% CI 1.13, 1.50), compared to heterosexual participants with no same-sex experience. The magnitudes of the risk ratios were high among bisexual participants for gHTN and preeclampsia and among lesbian/gay participants for gHTN. CONCLUSIONS: Some SM groups may be disparately burdened by GDM and HDP. Elucidating modifiable mechanisms (e.g., structural barriers, discrimination) for reducing adverse pregnancy outcomes among SM populations is critical.

Addressing Gaps in Access to LGBTQIA + Health Education Resources: A Novel E-Learning Platform.

OBJECTIVES: To reduce health inequities for lesbian, gay, bisexual, transgender, queer, intersex, asexual, and all sexually and gender diverse (LGBTQIA+) people, healthcare professionals need increased access to education and training resources on LGBTQIA + health. Web-based, asynchronous, electronic learning (e-learning) resources are critical for expanding the availability of LGBTQIA + health programs. This article presents the design and utilization outcomes of a novel e-learning platform for engaging healthcare professionals in LGBTQIA + health online continuing education. METHODS: As of December 2022, the e-learning platform consisted of 293 resources within 17 topic domains. Modalities included: learning modules, recorded webinars, publications, videos, and toolkits. We conducted a descriptive analysis of the e-learning platform's website traffic and user engagement data. Google Universal Analytics and event tracking were used to measure website traffic, user locations, and publication downloads. Learning module and webinar completions were exported from the learning management system and run as frequencies. RESULTS: Between January 1, 2020, and December 31, 2022, over 650,000 people from all U.S. states, 182 countries, and 31 territories visited the website. Platform users downloaded publications 66,225 times, and completed 29,351 learning modules and 24,654 webinars. CONCLUSION: The broad reach and high user engagement of the e-learning platform indicate acceptability of web-based, asynchronous online continuing education in LGBTQIA + health, and suggest that this platform is filling a need in health professional education. Remote, online learning opportunities may be especially important in jurisdictions with bans on medical care for transgender and gender diverse youth. Future growth of the platform, paired with in-person and other online learning opportunities, has the potential to reduce gaps in LGBTQIA + health training, and mitigate LGBTQIA + health inequities.

Prevalence of Gender-Affirming Surgical Procedures Among Minors and Adults in the US.

This cross-sectional study uses a national dataset to examine the prevalence of gender-affirming surgical procedures among minors and adults in the US.

Health Care Utilization and Care-seeking Behavior Among Vulnerabilized Sexual Minority Women: A Social-ecological Approach.

Sexual minority women (SMW) experience worse health than their heterosexual counterparts but have largely been omitted from health services research. To address this gap, we conducted 25 semi-structured, in-depth interviews with SMW. Transcripts were analyzed using thematic analysis, and findings were organized using a modified socioecological framework. Key themes at each socioecological level include (1) structural: stigma, sociocultural norms, health infrastructure; (2) organizational: stigma, patient-provider relationship, hours and location, linkage to care and co-location of services; (3) interpersonal: stigma and social support; (4) individual: internalized stigma, self-efficacy, socioeconomic status, health literacy, and intersecting identities. Stigma is the central theme affecting vulnerabilized SMW's experiences accessing care. Anti-stigma initiatives and factors that lead to personal resilience and can mitigate care access barriers were identified at each level. Interventions should focus on building inclusive policies/infrastructure and using SMW's unique social networks to empower and improve care access and health outcomes among vulnerabilized SMW.

Disparities in cancer incidence by sexual orientation.

INTRODUCTION: Cancer risk factors are more common among sexual minority populations (e.g., lesbian, bisexual) than their heterosexual peers, yet little is known about cancer incidence across sexual orientation groups. METHODS: The 1989-2017 data from the Nurses' Health Study II, a longitudinal cohort of female nurses across the United States, were analyzed (N = 101,543). Sexual orientation-related cancer disparities were quantified by comparing any cancer incidence among four sexual minority groups based on self-disclosure-(1) heterosexual with past same-sex attractions/partners/identity; (2) mostly heterosexual; (3) bisexual; and (4) lesbian women-to completely heterosexual women using age-adjusted incidence rate ratios (aIRR) calculated by the Mantel-Haenszel method. Additionally, subanalyses at 21 cancer disease sites (e.g., breast, colon/rectum) were conducted. RESULTS: For all-cancer analyses, there were no statistically significant differences in cancer incidence at the 5% type I error cutoff among sexual minority groups when compared to completely heterosexual women; the aIRR was 1.17 (95% CI,0.99-1.38) among lesbian women and 0.80 (0.58-1.10) among bisexual women. For the site-specific analyses, incidences at multiple sites were significantly higher among lesbian women compared to completely heterosexual women: thyroid cancer (aIRR, 1.87 [1.03-3.41]), basal cell carcinoma (aIRR, 1.85 [1.09-3.14]), and non-Hodgkin lymphoma (aIRR, 2.13 [1.10-4.12]). CONCLUSION: Lesbian women may be disproportionately burdened by cancer relative to their heterosexual peers. Sexual minority populations must be explicitly included in cancer prevention efforts. Comprehensive and standardized sexual orientation data must be systematically collected so nuanced sexual orientation-related cancer disparities can be accurately assessed for both common and rare cancers.

Adverse Obstetric and Perinatal Outcomes Among Birthing People in Same-Sex and Different-Sex Relationships in Louisiana.

Purpose: We investigated sexual orientation disparities in several obstetric and perinatal outcomes in Louisiana and examined whether these disparities differed among Black, Latine, and White populations. Methods: We analyzed cross-sectional vital records data on singleton live births in Louisiana (2016-2022). Same-sex relationships (SSR) vs. different-sex relationships (DSR) were classified based on the sex of the parents listed on the birth certificate. Using modified Poisson regression, we estimated adjusted risk ratios and 95% confidence intervals among birthing persons in SSR vs. DSR for preterm birth (PTB), low birthweight (LBW), spontaneous labor, Cesarean delivery, gestational hypertension, and gestational diabetes. We examined within and across group disparities in models stratified by sexual orientation and race/ethnicity. Results: In the total birthing population, those in SSR experienced higher risk of gestational hypertension and gestational diabetes and were less likely to have spontaneous labor compared with persons in DSR. The risk of PTB and LBW was two-fold higher among Black birthing people in SSR compared with White birthing people in SSR and DSR. Latine birthing people in SSR experienced higher risk of gestational hypertension and gestational diabetes compared with their peers in DSR and White people in DSR. Some of these disparities were partially explained by including socioeconomic and health risk factors. Conclusion: Sexual orientation-related disparities exist across and within racial/ethnic groups among birthing people in Louisiana. Adopting an intersectional approach that considers the mutually constituted nature of heterosexism and racism is critical to addressing sexual orientation-related inequities in reproductive and perinatal health.

Differences in medically assisted reproduction use by sexual identity and partnership: a prospective cohort of cisgender women.

STUDY QUESTION: Does medically assisted reproduction (MAR) use among cisgender women differ among those with same-sex partners or lesbian/bisexual identities compared to peers with different-sex partners or heterosexual identities? SUMMARY ANSWER: Women with same-sex partners or lesbian/bisexual identities are more likely to utilize any MAR but are no more likely to use ART (i.e. IVF, reciprocal IVF, embryo transfer, unspecified ART, ICSI, and gamete or zygote intrafallopian transfer) compared to non-ART MAR (i.e. IUI, ovulation induction, and intravaginal or intracervical insemination) than their different-sex partnered and completely heterosexual peers. WHAT IS KNOWN ALREADY: Sexual minority women (SMW) form families in myriad ways, including through fostering, adoption, genetic, and/or biological routes. Emerging evidence suggests this population increasingly wants to form genetic and/or biological families, yet little is known about their family formation processes and conception needs. STUDY DESIGN, SIZE, DURATION: The Growing Up Today Study is a US-based prospective cohort (n = 27 805). Participants were 9-17 years of age at enrollment (1996 and 2004). Biennial follow-up is ongoing, with data collected through 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: Cisgender women who met the following criteria were included in this sample: endorsed ever being pregnant; attempted a pregnancy in 2019 or 2021; and endorsed either a male- or female-sex partner OR responded to questions regarding their sexual identity during their conception window. The main outcome was any MAR use including ART (i.e. procedures involving micromanipulation of gametes) and non-ART MAR (i.e. nonmanipulation of gametes). Secondary outcomes included specific MAR procedures, time to conception, and trends across time. We assessed differences in any MAR use using weighted modified Poisson generalized estimating equations. MAIN RESULTS AND THE ROLE OF CHANCE: Among 3519 participants, there were 6935 pregnancies/pregnancy attempts and 19.4% involved MAR. A total of 47 pregnancies or pregnancy attempts were among the same-sex partnered participants, while 91 were among bisexual participants and 37 among lesbian participants. Participants with same-sex, compared to different-sex partners were almost five times as likely to use MAR (risk ratio [95% CI]: 4.78 [4.06, 5.61]). Compared to completely heterosexual participants, there was greater MAR use among lesbian (4.00 [3.10, 5.16]) and bisexual (2.22 [1.60, 3.07]) participants compared to no MAR use; mostly heterosexual participants were also more likely to use ART (1.42 [1.11, 1.82]) compared to non-ART MAR. Among first pregnancies conceived using MAR, conception pathways differed by partnership and sexual identity groups; differences were largest for IUI, intravaginal insemination, and timed intercourse with ovulation induction. From 2002 to 2021, MAR use increased proportionally to total pregnancies/pregnancy attempts; ART use was increasingly common in later years among same-sex partnered and lesbian participants. LIMITATIONS, REASONS FOR CAUTION: Our results are limited by the small number of SMW, the homogenous sample of mostly White, educated participants, the potential misclassification of MAR use when creating conception pathways unique to SMW, and the questionnaire's skip logic, which excluded certain participants from receiving MAR questions. WIDER IMPLICATIONS OF THE FINDINGS: Previous studies on SMW family formation have primarily focused on clinical outcomes from ART procedures and perinatal outcomes by conception method, and have been almost exclusively limited to European, clinical samples that relied on partnership data only. Despite the small sample of SMW within a nonrepresentative study, this is the first study to our knowledge to use a nonclinical sample of cisgender women from across the USA to elucidate family formation pathways by partnership as well as sexual identity, including pathways that may be unique to SMW. This was made possible by our innovative approach to MAR categorization within a large, prospective dataset that collected detailed sexual orientation data. Specifically, lesbian, bisexual, and same-sex partnered participants used both ART and non-ART MAR at similar frequencies compared to heterosexual and different-sex partnered participants. This may signal differential access to conception pathways owing to structural barriers, emerging conception trends as family formation among SMW has increased, and a need for conception support beyond specialized providers and fertility clinics.

Trajectories of Mental Distress Among US Women by Sexual Orientation and Racialized Group During the First Year of the COVID-19 Pandemic.

Objectives. To describe longitudinal trends in the prevalence of mental distress across the first year of the COVID-19 pandemic (April 2020‒April 2021) among US women at the intersection of sexual orientation and racialized group. Methods. Participants included 49 805 cisgender women and female-identified people from the COVID-19 Sub-Study, a cohort of US adults embedded within the Nurses' Health Studies 2 and 3 and the Growing Up Today Study. We fit generalized estimating equation Poisson models to estimate trends in depressive and anxiety symptoms by sexual orientation (gay or lesbian, bisexual, mostly heterosexual, completely heterosexual); subsequent models explored further differences by racialized group (Asian, Black, Latine, White, other or unlisted). Results. Relative to completely heterosexual peers, gay or lesbian, bisexual, and mostly heterosexual women had a higher prevalence of depressive and anxiety symptoms at each study wave and experienced widening inequities over time. Inequities were largest for sexual minority women of color, although confidence intervals were wide. Conclusions. The COVID-19 pandemic may have exacerbated already-glaring mental health inequities affecting sexual minority women, especially those belonging to marginalized racialized groups. Future research should investigate structural drivers of these patterns to inform policy-oriented interventions. (Am J Public Health. 2024;114(5):511-522. https://doi.org/10.2105/AJPH.2024.307601).

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.

Barriers to Cervical Cancer Screening by Sexual Orientation Among Low-Income Women in North Carolina.

We sought to examine cervical cancer screening barriers by sexual orientation among low-income women in North Carolina. The MyBodyMyTest-3 Trial recruited low-income women (< 250% of federal poverty level) aged 25-64 years who were 1+ year overdue for cervical cancer screening. We compared perceptions of cervical cancer screening among those who self-identified as lesbian, gay, bisexual, or queer (LGBQ; n = 70) to straight/heterosexual women (n = 683). For both LGBQ and straight respondents, the greatest barriers to screening were lack of health insurance (63% and 66%) and cost (49% and 50%). LGBQ respondents were more likely than straight respondents to report forgetting to screen (16% vs. 8%, p = .05), transportation barriers (10% vs. 2%, p = .001), and competing mental or physical health problems (39% vs. 27%, p = .10). Addressing access remains important for improving cervical cancer screening among those under-screened. For LGBQ women, additional attention may be needed for reminders, co-occurring health needs, and transportation barriers.

Development of a mentor training curriculum to support LGBTQIA+ health professionals.

While mentors can learn general strategies for effective mentoring, existing mentorship curricula do not comprehensively address how to support marginalized mentees, including LGBTQIA+ mentees. After identifying best mentoring practices and existing evidence-based curricula, we adapted these to create the Harvard Sexual and Gender Minority Health Mentoring Program. The primary goal was to address the needs of underrepresented health professionals in two overlapping groups: (1) LGBTQIA+ mentees and (2) any mentees focused on LGBTQIA+ health. An inaugural cohort (N = 12) of early-, mid-, and late-career faculty piloted this curriculum in spring 2022 during six 90-minute sessions. We evaluated the program using confidential surveys after each session and at the program's conclusion as well as with focus groups. Faculty were highly satisfied with the program and reported skill gains and behavioral changes. Our findings suggest this novel curriculum can effectively prepare mentors to support mentees with identities different from their own; the whole curriculum, or parts, could be integrated into other trainings to enhance inclusive mentoring. Our adaptations are also a model for how mentorship curricula can be tailored to a particular focus (i.e., LGBTQIA+ health). Ideally, such mentor trainings can help create more inclusive environments throughout academic medicine.

Restrictive abortion legislation and adverse mental health during pregnancy and postpartum.

PURPOSE: To determine the impact of abortion legislation on mental health during pregnancy and postpartum and assess whether pregnancy intention mediates associations. METHODS: We quantified associations between restrictive abortion laws and stress, depression symptoms during and after pregnancy, and depression diagnoses after pregnancy using longitudinal data from Nurses' Health Study 3 in 2010-2017 (4091 participants, 4988 pregnancies) using structural equation models with repeated measures, controlling for sociodemographics, prior depression, state economic and sociopolitical measures (unemployment rate, gender wage gap, Gini index, percentage of state legislatures who are women, Democratic governor). RESULTS: Restrictive abortion legislation was associated with unintended pregnancies (ß = 0.127, p = 0.02). These were, in turn, associated with increased risks of stress and depression symptoms during pregnancy (total indirect effects ß = 0.035, p = 0.03; ß = 0.029, p = 0.03, respectively, corresponding <1% increase in probability), but not after pregnancy. CONCLUSIONS: Abortion restrictions are associated with higher proportions of unintended pregnancies, which are associated with increased risks of stress and depression during pregnancy.

Breast and cervical cancer screenings across gender identity: results from the Behavioral Risk Factor Surveillance System before and during the COVID-19 pandemic.

PURPOSE: Although national medical organizations often neglect to include trans and gender diverse (TGD) people in their breast and cervical cancer screening recommendations, the World Profession Association of Transgender Health recommends that TGD people who are at risk for these cancers follow existing guidelines for cisgender women. Despite WPATH's recommendations, TGD people are less likely to get screened in large part due to discrimination. The COVID-19 pandemic has limited access to cancer screenings among cisgender people, but it is unknown how this has impacted TGD people. METHODS: Using national survey data from the Behavioral Risk Factors Surveillance System (BRFSS), we examined differences in cervical and breast cancer screening noncompliance across gender identity at two time points: before and during the COVID-19 pandemic. RESULTS: Screening noncompliance increased during the COVID-19 pandemic among cisgender and TGD people (e.g., transgender men, gender non-conforming people). Compared to cisgender women, transgender men and gender non-conforming respondents had higher odds of breast cancer screening noncompliance before and during COVID-19. Transgender men had lower odds of cervical cancer screening noncompliance than cisgender women before COVID-19, but higher odds during the pandemic. Gender non-conforming respondents also had lower odds of cervical cancer screening noncompliance during COVID-19 compared to cisgender women. CONCLUSIONS: Screening noncompliance for breast and cervical cancer was more common among TGD people than cisgender women; while these disparities existed before the COVID-19 pandemic, they were exacerbated during the pandemic. Future work should move beyond descriptive statistics and elucidate underlying causes to inform interventions.

The association between preconception cannabis use and gestational diabetes mellitus: The Preconception Period Analysis of Risks and Exposures Influencing health and Development (PrePARED) consortium.

BACKGROUND: The metabolic changes that ultimately lead to gestational diabetes mellitus (GDM) likely begin before pregnancy. Cannabis use might increase the risk of GDM by increasing appetite or promoting fat deposition and adipogenesis. OBJECTIVES: We aimed to assess the association between preconception cannabis use and GDM incidence. METHODS: We analysed individual-level data from eight prospective cohort studies. We identified the first, or index, pregnancy (lasting ≥20 weeks of gestation with GDM status) after cannabis use. In analyses of pooled individual-level data, we used logistic regression to estimate study-type-specific odds ratios (OR) and 95% confidence intervals (CI), adjusting for potential confounders using random effect meta-analysis to combine study-type-specific ORs and 95% CIs. Stratified analyses assessed potential effect modification by preconception tobacco use and pre-pregnancy body mass index (BMI). RESULTS: Of 17,880 participants with an index pregnancy, 1198 (6.7%) were diagnosed with GDM. Before the index pregnancy, 12.5% of participants used cannabis in the past year. Overall, there was no association between preconception cannabis use in the past year and GDM (OR 0.97, 95% CI 0.79, 1.18). Among participants who never used tobacco, however, those who used cannabis more than weekly had a higher risk of developing GDM than those who did not use cannabis in the past year (OR 2.65, 95% CI 1.15, 6.09). This association was not present among former or current tobacco users. Results were similar across all preconception BMI groups. CONCLUSIONS: In this pooled analysis of preconception cohort studies, preconception cannabis use was associated with a higher risk of developing GDM among individuals who never used tobacco but not among individuals who formerly or currently used tobacco. Future studies with more detailed measurements are needed to investigate the influence of preconception cannabis use on pregnancy complications.
