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.

Gender(ed) science: How the institutionalization of gender continues to shape the conduct and content of women's health research.

Gender refers to the socially constructed roles, behaviors, and attributes that a particular society considers appropriate for men and women based on assumptions about biological sex. It also operates as a major social organizing principle that confers unequal power, status, and resources to men and women, with direct consequences for health. Historic patriarchal and misogynistic beliefs and values are reinforced through social institutions, including health science, which reify gender inequities. This commentary examines two key domains in which the social organization and institutionalization of gender in scientific research affect the conduct of women's health research and, by extension, women's health outcomes. These domains are: 1) decisions about which topics are prioritized, researched, and funded and 2) the dissemination of research findings. Using the National Institutes of Health (NIH) as a case study to illustrate broader patterns in scientific research, we present evidence of gender-based inequities in what is prioritized, deemed fundable, and disseminated, and how this affects knowledge production and attention to women's health. We highlight efforts and progress made by the NIH and call for additional attention to further address gender-based inequities and their impact on women's health research. We conclude with a call for critical social science analyses-ideally supported by the NIH-of the social organization of health science research to identify points of intervention for redressing deep-seated obstacles to advancing research on women's health.

Structural heteropatriarchy and maternal cardiovascular morbidities.

The United States has some of the poorest maternal health outcomes of any developed nation. Existing research on maternal cardiovascular morbidities has focused predominantly on individual- and clinic-level drivers, but we know little about community- and structural-level factors that shape these outcomes. We use a composite measure of "structural heteropatriarchy" which includes measures of structural sexism and structural LGB-stigma to examine the relationship between structural heteropatriarchy and three cardiovascular-related maternal morbidities using the National Longitudinal Study of Adolescent to Adult Health (n = 3928). Results using multivariate regressions show that structural heteropatriarchy is associated with increased risk of reporting maternal morbidities. Our findings provide further evidence that sexuality- and gender-based stigma operate together to shape health disparities, including maternal 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.

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.

Structural stigma and alcohol use among sexual and gender minority adults: A systematic review.

Background: Sexual and gender minority (SGM) people are more likely than their cisgender, heterosexual counterparts to report negative alcohol-related outcomes. Although the association between individual- and interpersonal-level minority stressors and negative alcohol-related outcomes among SGM people is well-established, structural-level minority stressors are understudied. This systematic review examined structural-level stigma and alcohol-related outcomes among SGM people to inform future research, interventions, and policy. Methods: We used five electronic databases to search for studies published between January 2010 and May 2022 that examined associations between structural stigma and alcohol use among SGM adults in the United States. Peer-reviewed, quantitative studies available in English were included. We conducted quality appraisal using the Joanna Briggs Institute checklist. Results: The final sample included 11 studies. Overall, there was moderate to strong support for a positive association between structural stigma and negative alcohol-related outcomes among SGM people, with differences by gender, sexual identity, race, and ethnicity. All studies used cross-sectional designs, and nearly half utilized non-probability samples. Transgender and nonbinary people, SGM people of color, and sexual identity subgroups beyond gay, lesbian, and heterosexual were underrepresented. Structural stigma was most commonly measured as a state-level index. Alcohol measures were heterogeneous. Multilevel stigma and resiliency factors were understudied. Conclusions: Addressing structural stigma is critical in reducing negative alcohol-related outcomes and inequities among SGM people. Research is needed that includes probability samples, longitudinal designs, and samples that reflect the diversity of SGM people. Future studies should examine the influence of multilevel stigma and resiliency factors on alcohol-related outcomes.

Sexual Orientation-Related Nondiscrimination Laws and Maternal Hypertension Among Black and White U.S. Women.

Background: Black women and sexual minority women are more likely to report adverse maternal health. Little research has investigated maternal health disparities at the intersection of race/ethnicity and sexual orientation or the mechanisms that contribute to these disparities. Materials and Methods: We analyzed data from the National Longitudinal Study of Adolescent to Adult Health. Our sample was restricted to Black and White women who had at least one live birth and were followed-up in Wave V of the data (n = 3,396). We used multivariable logistic regression to analyze the associations between race, sexual orientation identity, and a four-item state-level index of sexual orientation-related nondiscrimination laws. Results: We found that higher numbers of state-level sexual orientation-related nondiscrimination laws were associated with lower risk of maternal hypertension among U.S. women overall (odds ratio [OR] = 0.82, 95% confidence interval [CI] 0.73-0.93), and Black women had a higher risk of maternal hypertension relative to White women (OR = 1.32, 95% CI 1.00-1.79). Interactions between race, sexual orientation identity, and sexual orientation-related policies show that, regardless of sexual orientation identity, sexual orientation-related nondiscrimination laws were associated with a lower risk of maternal hypertension among White mothers (OR = 0.80, 95% CI 0.70-0.92). However, among Black women, these laws were associated with a lower risk of maternal hypertension among lesbian and bisexual women (OR = 0.18, 95% CI 0.05-0.68) only. Conclusions: Laws that prevent discrimination related to sexual orientation in various societal domains may play an important role in improving maternal health outcomes among White women in general and Black lesbian and bisexual women in particular.

Associations of adult roles and minority stressors with trajectories of alcohol dependence symptoms throughout adulthood among sexual minority women.

OBJECTIVE: In the present study, we sought to identify trajectories of symptoms of potential alcohol dependence (AD) among adult sexual minority women (SMW). Theoretical correlates were examined in relation to the empirically identified trajectories. METHOD: Data were collected at three time points between 2000 and 2012 from SMW drinkers (n = 434) enrolled in a longitudinal study (M Age = 37.49 at baseline, SD = 11.55). Using an accelerated-cohort longitudinal design, latent growth curve mixture models identified homogeneous patterns of any past-year symptoms of potential AD. Correlates of trajectories included alcohol-related developmental risk factors, adult roles, and exposure to minority stressors. RESULTS: Three trajectories were identified that captured risk of symptoms of potential AD over time, reflecting: (a) relatively consistent, low risk over time; (b) deceleration in risk throughout adulthood; (c) relatively persistent, high risk over time. Consistent with prior work, SMW drinkers who reported higher levels of perceived stigma or masculinity showed persistently high risk of reporting at least one past-year symptom of potential AD. CONCLUSIONS: Most SMW drinkers report deceleration in risk of AD symptoms over time. Findings have implications for prevention and intervention efforts tailored to SMW drinkers.

Adverse pregnancy and birth outcomes in sexual minority women from the National Survey of Family Growth.

BACKGROUND: Few studies have examined how multiple marginalized identities are associated with adverse pregnancy and birth outcomes, especially for Black and Hispanic sexual minority women. Sexual minorities are people who identify as lesbian, gay, bisexual or transgender (LGBT). The purpose of this study was to examine differences in adverse pregnancy (i.e., miscarriage) and birth outcomes (i.e., preterm birth, low birthweight, and stillbirth) in a national sample of women by race and ethnicity, and sexual minority status (LGBT identification and same-sex sexual behavior). METHODS: We conducted a cross-sectional analysis of the National Survey of Family Growth (NSFG). The unit of analysis was pregnancy, not participants. In this study, we examined pregnancies to participants who identified as heterosexual, lesbian, and bisexual, by race and Hispanic ethnicity. We also studied sexual behaviors to categorize participants as women who have sex with women (WSW) and women who have sex with men (WSM). Outcomes included preterm birth, low birthweight, miscarriage, and stillbirth. We employed logistic and linear regression analyses for analyses using STATA. RESULTS: We studied 53,751 pregnancies, and 9% of these occurred in people who identified as heterosexual, but had engaged in sexual activity with a female partner (heterosexual-WSW), 7% in those identifying as bisexual, and 1% to women who identified as lesbian. Pregnancies ended in preterm birth (10.7%) and low birthweight (9.0%), stillbirths (2-4%), and miscarriages (17-21%) in sexual minority women. We observed that pregnancies reported by Hispanic lesbian women had a higher birthweight (ß = 10.71, SE = 4.1, p-value = 0.01) compared to infants born to Hispanic heterosexual-WSM. Pregnancies to lesbian women were significantly more likely to end in stillbirth (aRR = 3.58, 95% CI 1.30,9.79) compared to heterosexual-WSM. No significant differences were noted in risk of adverse birth outcomes by sexual orientation for NH Black or Hispanic women. CONCLUSION: In this sample, preterm births were less likely to occur among heterosexual-WSW than in heterosexual-WSM. Pregnancies to lesbians and bisexual women were more likely to end in miscarriage or stillbirth than heterosexual WSM. Lesbian Hispanic women reported higher birthweights compared to heterosexual-WSM Hispanic women. More research should be done to further understand these findings.

Mothers' Sexual Identity and Children's Health.

Sexual minority women face a plethora of structural, socioeconomic, and interpersonal disadvantages and stressors. Research has established negative associations between women's sexual minority identities and both their own health and their infants' birth outcomes. Yet a separate body of scholarship has documented similarities in the development and well-being of children living with same-sex couples relative to those living with similarly situated different-sex couples. This study sought to reconcile these literatures by examining the association between maternal sexual identity and child health at ages 5-18 using a US sample from the full population of children of sexual minority women, including those who identify as mostly heterosexual, bisexual, or lesbian, regardless of partner sex or gender. Analyses using data from the National Longitudinal Study of Adolescent to Adult Health (N=8,978) followed women longitudinally and examined several measures of their children's health, including general health and specific developmental and physical health conditions. Analyses found that children of mostly heterosexual and bisexual women experienced health disadvantages relative to children of heterosexual women, whereas the few children of lesbian women in our sample evidenced a mixture of advantages and disadvantages. These findings underscore that to understand sexual orientation disparities and the intergenerational transmission of health, it is important to incorporate broad measurement of sexual orientation that can capture variation in family forms and in sexual minority identities.

Examining Differences in Alcohol and Smoking Behaviors between Parenting and Nonparenting Lesbian Women.

BACKGROUND: The transition to parenthood is a significant life event that has implications for health behaviors and health. Few studies have examined alcohol use and smoking by parenthood status (nonparent vs. parent) among women who identify as lesbian. METHODS: This study used data from two longitudinal studies, the Chicago Health and Life Experiences of Women Study (n = 135) and the U.S. National Longitudinal Lesbian Family Study (n = 116), to compare problem drinking and cigarette smoking trajectories among lesbian-identified women by parenthood status. We used mixed models to investigate differences in problem drinking and cigarette smoking in three waves of data in each study. RESULTS: Lesbian parents reported significantly less problem drinking, but not cigarette smoking, than nonparent lesbian women. When considering the interaction between parental status and time, problem drinking was significantly higher among nonparents than parents at each time interval. CONCLUSIONS: Parenthood was associated with positive changes in drinking among lesbian women; however, more research is needed to understand how to support smoking cessation among parenting lesbian women.

Gender self-concept and hazardous drinking among sexual minority women: Results from the Chicago health and life experiences of women (CHLEW) study.

OBJECTIVE: Sexual minority women (SMW; e.g., lesbian, bisexual) report substantially higher rates of hazardous drinking (HD) than heterosexual women.Yet, few studies have examined sub-group differences. In this study, we investigated the relationship between gender self-concept and HD among SMW. Research consistently shows a link between heavier drinking and masculinity. SMW are more likely than heterosexual women to be gender nonconforming, and masculinity among SMW is associated with increased minority stress, a key HD risk factor. METHODS: We used Wave 3 data from the Chicago Health and Life Experiences of Women study, a longitudinal study of SMW (N = 598), which assessed participants' self-perceived levels of masculinity and femininity and their perception of how masculine/feminine others viewed them. Using multivariable logistic regression, we examined the association between gender self-concept and past 12-month heavy episodic drinking (HED), drinking-related problems, and alcohol dependence. RESULTS: Controlling for demographics and minority stress, greater masculinity (both self-perceived and perceptions by others) was associated with higher odds of HED and alcohol dependence. Masculinity as perceived by others was associated with higher odds of drinking-related problems. Neither femininity measure was associated with HD. Additionally, minority stress (i.e., discrimination, stigma, internalized stigma) did not account for the relationship between gender self-concept and HD. CONCLUSIONS/IMPORTANCE: In this sample, masculinity, particularly SMW's beliefs that others viewed them as masculine, was associated with HD. This association was not attributable to differences in minority stress and may be related to differences in gendered drinking norms, which could be targeted in intervention studies.

State-Level Regulations Regarding the Protection of Sexual Minorities and Birth Outcomes: Results From a Population-Based Cohort Study.

OBJECTIVE: We leverage state-level variability in social policies that confer legal protections for sexual minorities (e.g., employment nondiscrimination acts) and examine their association with birth outcomes among sexual minority women. METHODS: We link measures of structural protections (i.e., social policies) to a prospective, population-based cohort of US adults-the National Longitudinal Study of Adolescent to Adult Health ( n = 7913 total singleton births, n = 274 singleton births to bisexual women, n = 53 singleton births to lesbian women)-which includes measurement of key risk factors for birth outcomes over the life course. RESULTS: Lesbian, gay, bisexual (LGB) policy protections were associated with better birth outcomes for lesbian women. For example, among lesbian women, the predicted birth weight for infants in states with no policy protections was 3.01 kg (95% confidence interval = 2.71-3.30) but was 3.71 kg (95% confidence interval = 3.46-3.96) in states with three or four policy protections. In negative control analyses, there was no association between LGB policy protections and birth outcomes among the nonstigmatized group (i.e., heterosexual women), providing evidence of specificity. Furthermore, in states with the most LGB policy protections, lesbian women were at lower risk for preterm births and had infants with higher birth weights than heterosexual and bisexual women. These associations remained robust after adjusting for 13 risk factors, including demographics, prior and current indicators of socioeconomic status, preconception and perinatal risk factors, and neighborhood characteristics. CONCLUSIONS: These results provide novel evidence that sexual orientation-related policy protections, measured at the state level, are associated with a decreased risk for adverse birth outcomes among lesbian women.

Sexual Fluidity and Psychological Distress: What Happens When Young Women's Sexual Identities Change?

The sexual identities of young women today are less binary and more fluid than ever before. Several theoretical perspectives imply that this fluidity could be accompanied by distress. To examine this, we analyzed four waves of data from Australian women born 1989 to 1995 (n = 11,527). We found no evidence of a universal association between sexual identity change and psychological distress. Instead, psychological distress was elevated when women changed their identity away from the heterosexual norm and lowered when they changed their identity toward it. Social stress partly attenuated these associations. In addition, women unsure of their identity at multiple assessment points reported significantly greater psychological distress in the final assessment than women who were never unsure. Our findings suggest that greater support should be offered to women who are questioning their sexual identity or developing a minority identity.

Sexual Orientation Disparities in Experiences of Male-Perpetrated Intimate Partner Violence: A Focus on the Preconception and Perinatal Period.

INTRODUCTION: Compared with their heterosexual counterparts, sexual minority women (SMW), especially those with male partners, are at increased risk for intimate partner violence (IPV). IPV has been linked to a variety of adverse maternal, infant, and child health outcomes. However, to date, no research has examined SMW's experiences of IPV in the context of pregnancy. This study explored whether SMW were more likely than exclusively heterosexual women with only male sexual partners (WSM) to report a variety of forms of IPV perpetrated by their male partner before or during pregnancy. METHODS: Data are from the National Longitudinal Study of Adolescent to Adult Health (Add Health). Our sample size ranged from 10,081 to 10,328 pregnancies, matched with their male pregnancy partner, reported by 3,828 to 3,873 women. RESULTS: Logistic regression results indicated that compared with heterosexual-WSM, mostly heterosexual women and heterosexual-women who have sex with women (WSW) were more likely to report any IPV, mostly heterosexual women were more likely to report an IPV-related injury, and heterosexual-WSW were more likely to report sexual assault. CONCLUSIONS: Results suggest that mostly heterosexual and heterosexual-WSW are at increased risk of experiencing multiple forms of IPV with their male pregnancy partners, highlighting the need for additional screening and prevention efforts to reduce IPV and its negative sequelae.

Sex, poverty, and public health: Connections between sexual wellbeing and economic resources among US reproductive health clients.

OBJECTIVE: To document associations between socioeconomics and indicators of sexual wellbeing. METHODS: We obtained our data from the HER Salt Lake Initiative, a large, longitudinal cohort study of family planning clients in the United States who accessed free contraceptive services between March 2016 and March 2017. Baseline socioeconomic measures included Federal Poverty Level, receipt of public assistance, and difficulty paying for housing, food, and other necessities. Sexual wellbeing measures assessed sexual functioning and satisfaction, frequency of orgasm, and current sex-life rating. Among participants who had been sexually active in the last month (N = 2581), we used chi-square tests to examine bivariate associations between sexual and socioeconomic measures. RESULTS: We found strong and consistent relationships between sexual wellbeing and economic resources: those reporting more socioeconomic constraints also reported fewer signs of sexual flourishing. CONCLUSIONS: Financial scarcity appears to constrain sexual wellbeing. To support positive sexual health, the public health field must continue to focus on economic reform, poverty reduction, and dismantling of structural classism as critical aspects of helping people achieve their full health and wellbeing potential.

Measuring the Sexual Acceptability of Contraception: Psychometric Examination and Development of a Valid and Reliable Prospective Instrument.

BACKGROUND: People's sexual experiences have a strong association with contraceptive satisfaction and continuation, but no measures exist to specifically assess contraceptive-related sexual acceptability. AIM: This study developed and examined the psychometric properties of reliability, separation, and item fit of a new Contraceptive Sexual Acceptability (CSA) instrument. METHODS: Enrolled participants initiating a new contraceptive method from the HER Salt Lake longitudinal cohort study contributed baseline survey responses for scale development. The study included the Female Sexual Function Index, the New Sexual Satisfaction Scale, measures of physical and mood-related side effects, and self-reported perceptions of contraception's sexual impacts. Items from these measures' served as the basis for analyses. We analyzed responses using descriptive techniques and modeled using exploratory factor (EFA) and bifactor analyses (BFA). The Masters' Partial Credit Rasch method modeled reliability, separation, and item fit statistics. Here we evaluate (i) the reproducibility of relative measure location on the modeled linear latent variable, (ii) the number of statistically unique performance levels that can be distinguished by the measure, and (iii) the discrepancy between item responses and expectations of the model. Psychometric findings and theoretical models informed item reduction and final scale development. OUTCOMES: We developed a 10-item Contraceptive Sexual Acceptability scale that exceeded the thresholds and sufficiently covered domains for use in contraceptive research and clinical settings. RESULTS: Starting with data on 39-items from 4,387 individuals, we identified 10-items that best measured the CSA latent construct. The Rasch model included a total of 5 calibrations. We reduced items based on bifactor analysis and surpassed unidimensionality thresholds (OH = 0.84, ECV = 0.74) set a priori. The final items included questions with scaled responses about pleasure and orgasm (orgasm quality, orgasm frequency, giving partner pleasure), physical (arousal and function) and psychological (emotional connection, surrender) components, general questions of satisfaction and frequency, and a measure of perceived impact of contraception on sexual experiences in the previous 4 weeks. CLINICAL IMPLICATIONS: The 10-item CSA instrument covers physical and psychological aspects of contraceptive sexual acceptability and can be used in clinical settings. STRENGTHS & LIMITATIONS: The unidimensional CSA instrument offers a brief, yet comprehensive assessment of sexual acceptability. Given the limited diversity of the sample, implementation of this scale in contraceptive research and clinical interactions should be evaluated and validated in more diverse settings. CONCLUSION: Attuning to sexual acceptability could ultimately help contraceptive clients find methods that better meet their needs and preferences. Sanders JN, Kean J, Zhang C, et al.

Understanding the Link Between Adolescent Same-Gender Contact and Unintended Pregnancy: The Role of Early Adversity and Sexual Risk Behavior.

Past research suggests an apparent paradox: Women who engage in same-gender sexual behavior show higher rates of unintended pregnancy than women with exclusive other-gender sexual behavior. Such women also have disproportionate rates of early adversity (both harshness, such as abuse or neglect, and unpredictability, such as father absence). We used the Add Health data (N = 5,617 cisgender women) to examine the relative contributions of early adversity, adolescent same-gender sexual behavior, and general sexual risk behavior to women's risks for adult unintended pregnancy. Women who engaged in adolescent same-gender sexual behavior were more likely to report childhood adversity, and both childhood adversity and adolescent same-gender behavior made independent contributions to subsequent rates of unintended pregnancy. The association between adolescent same-gender sexual behavior and adult unintended pregnancy was partially attributable to the fact that women with adolescent same-gender sexual behavior engaged in greater sexual risk behavior more broadly. These findings suggest that same-gender sexual behavior in adolescence may relate to a broader set of sexual risk behaviors that augment future risk for unintended pregnancy, independent of sexual identity. We draw on life history theory to explain this pattern of results and suggest directions for future research.
