Racial-ethnic, gender identity, and sexual orientation disparities in COVID-19-related social and health outcomes: A decomposition analysis

Despite the growing literature on racial-ethnic disparities during the pandemic, less is known about the explanatory mechanisms of these disparities and inequalities across other axes, such as gender and sexual identities. We studied the levels and sources of racial-ethnic, gender identity, and sexual minority disparities in social (i.e., unmet resource needs) and health (i.e., hospitalization) outcomes among individuals diagnosed with COVID-19, hypothesizing differential age structure, underlying health, and work and living arrangements as contributors to inequalities. Using large-scale administrative data from Chicago and adjusting for covariates, we found substantial racial-ethnic and gender identity disparities in both outcomes, and weak evidence of sexual minority disparities in unmet needs. Subsequent decomposition analyses revealed that living in larger households, having a higher share of non-adult cases, and facing higher burdens of chronic illness, obesity, and unemployment each statistically significantly drove racial-ethnic disparities in unmet needs, but these together explained less than 15% of the disparities. Similarly, about 20% of the Black-White gap in hospitalization resulted from disparities in underlying health and unemployment, whereas a higher proportion of non-adult cases or higher unemployment rates respectively proved the only significant pathways to partially explain transgender individuals’ disadvantages in unmet needs (12%) or hospitalization (6%). These findings highlight the importance of considering multiple dimensions of social differences in studying health disparities, the vulnerabilities of transgender and non-adult communities during the pandemic, and the valid yet quite limited roles of previously suggested sociodemographic factors in accounting for COVID-19-related categorical inequalities.

Sexual Orientation and Labor Market Disparities

This paper assesses labor market disparities against sexual minorities. My empirical strategy allows schooling, employment, and income to be endogenously determined relying on the identification of unobserved heterogeneity (skills and sexual orientation). I find that disparities are more prevalent at the employment margin than at the earnings margin. Sexual minorities are 10–20 percentage points less likely to be employed than comparable heterosexual adults. The results suggest that selection into employment contributes to the elimination of the observed income gaps among the employed as the average sexual-minority worker is more skilled than their heterosexual counterpart.

Sexual orientation disparities in developmental assets among youth: The mediating role of bullying victimization

BackgroundNavigating the developmental transition from adolescence to young adulthood while simultaneously integrating the emergence of a sexual minority identity can be overwhelming for lesbian, gay, bisexual, and questioning youth as the developmental tasks pose tremendous challenges to the cultivation of developmental assets, which are the building blocks necessary for fostering positive youth development and thriving. ObjectivesThe present study aimed to estimate the sexual orientation disparities in bullying victimization and developmental assets, investigate whether these sexual orientation differences varied by sex assigned at birth, and examine the mediating role of bullying victimization in the association between sexual orientation and developmental assets. MethodsThis study included a national sample of 3020 Chinese youth (51.5 % assigned male at birth; 48.5 % assigned female at birth) with a mean age of 15.71 years. They completed a self-report questionnaire on experiences of bullying victimization and developmental assets. ResultsSexual minority and questioning youth showed significantly lower levels of developmental assets than heterosexual youth. The sexual orientation differences in developmental assets did not significantly differ by sex assigned at birth. In addition, sexual minority youth were at heightened risk of relational bullying than heterosexual youth. The results obtained from the structural equation modeling indicated that bullying victimization mediated the association of sexual orientation with developmental assets. Compared to heterosexual youth, sexual minority youth were more likely to be subjected to bullying, which was linked to lower levels of developmental assets. ConclusionsThe study shows sexual orientation disparities in developmental assets among youth in China and reveals that the positive development of sexual minority youth may be hindered by their experiences of bullying victimization. The implications for positive psychological interventions and anti-bullying policies in Chinese educational settings are discussed.

Racial/ethnic and sexual orientation disparities in adverse childhood experiences, marijuana use and subjective cognitive decline: A mediational approach

AbstractBackgroundAdverse childhood experiences (ACEs) have been shown to be positively associated with substance use and abuse, and have also been linked to subjective cognitive decline (SCD). However, studies examining potential pathways between ACEs and SCD are lacking. In addition, this relationship and related pathways may differ by race/ethnicity and sexual orientation. The aim of this study was to determine the mediational role of marijuana use in the association between ACEs and SCD. The secondary aim was to determine the potential disparities by race/ethnicity and sexual orientation.MethodData were obtained from the 2019 Behavioral Risk Factor Surveillance System (N = 14,248). Path analysis was used to determine the mediating role of marijuana use between ACEs and SCD. Overall analyses adjusted for gender, age, income, education, employment and race/ethnicity. Stratified path analyses by race/ethnicity and sexual orientation were also conducted.ResultOverall, there was a direct association between ACEs and marijuana use (B = 0.102, p = <0.001), marijuana use and cognitive decline (B = 0.119, p<0.001); and between ACEs and cognitive decline (B = 0.047, p<0.001). There was an indirect association where marijuana use mediated the association between ACEs and SCD (B = 0.005, p<0.001). Stratified analyses by race/ethnicity found that marijuana use mediated the association between ACEs and SCD among White (B = 0.003, p<0.001), but not Black, Other or Hispanic respondents. Stratified analyses by sexual orientation found that marijuana use mediated the association between ACEs and SCD among heterosexual (B = 0.002, p = 0.006) but not LGBT respondents.ConclusionDisparities by race and sexual orientation existed in the mediating pathway of ACEs and SCD. Intervention programs addressing early trauma and cognitive function should consider these disparities. Future research should examine additional pathways between ACEs and SCD, especially for racial/ethnic and sexual minority populations.

Childhood Sexual Trauma and Subjective Cognitive Decline: An Assessment of Racial/Ethnic and Sexual Orientation Disparities.

Prior studies examining the association between childhood sexual abuse (CSA) and subjective cognitive decline (SCD) are limited. The aim of this study was to examine the racial/ethnic and sexual orientation disparities in the association between CSA and SCD. Using data from the 2019 Behavioral Risk Factor Surveillance System Survey, crude and multivariable logistic regression models were used to determine the association between CSA and SCD adjusting for sociodemographic characteristics, diabetes, hypertension, and depression. There were statistically significant differences in CSA status by age, gender, income, education, employment, and health status (depression). Black and Hispanic/Latine respondents had a stronger relationship between CSA and SCD compared to White populations. Also, sexual minority populations had a stronger relationship between CSA and SCD compared to heterosexual populations. Health disparities exist in the association between CSA and SCD. Trauma-informed interventions should be implemented among affected populations.

Sexual Orientation Disparities in Early Adolescent Sleep: Findings from the Adolescent Brain Cognitive Development Study.

Purpose: The purpose of this study was to examine associations between sexual minority status (e.g., gay or bisexual) and sleep problems in a demographically diverse, national sample of U.S. early adolescents. Methods: We analyzed cross-sectional data from the Adolescent Brain Cognitive Development Study (Year 2, 2018-2020) to estimate associations between sexual orientation and sleep problems or disturbance, adjusting for confounders and testing potential mediators (depressive problems, stress problems, family conflict, and parental monitoring). Results: In a sample of 8563 adolescents 10- to 14-years-old, 4.4% identified as sexual minority individuals. Sexual minority status was associated with self-reported trouble falling or staying asleep (risk ratio [RR] = 2.24, 95% confidence interval [CI] = 1.88-2.68) and caregiver-reported sleep disturbance (RR = 1.50, 95% CI = 1.29-1.75). The association between sexual minority status and trouble falling or staying asleep was partially mediated by greater depressive problems, more family conflict, and less parental monitoring, whereas the association between sexual minority status and caregiver-reported sleep disturbance was partially mediated by greater depressive problems, higher stress, and greater family conflict. Conclusions: Our results indicate that sexual minority status may be linked to sleep disturbance in early adolescence. Depressive problems, stress, family conflict, and less parental monitoring partially mediate disparities in sleep health for sexual minority youth. Future research could test interventions to promote family and caregiver acceptance and mental health support for sexual minority youth to improve their sleep and other health outcomes.

Associations between sex differences, eating disorder behaviors, physical and mental health, and self-harm among Chinese adolescents

Background and aimEating Disorders (ED) result in impaired well-being, but there exist an insufficient number of studies that have focused on the influence of sex and sexual orientation disparities within ED behaviors. Thus, we aimed to investigate ED behaviors among male and female adolescents with different sexual orientations in a school sample to understand prevalence and correlates of different ED behaviors.MethodData was analysed from 11,440 Chinese school adolescents with a mean age of 14.74 years (SD = 1.46). Reported data was gathered on sociodemographic information including sexual orientation, ED behaviors, health factors (reported health, cognitive function), mental health factors (depression, anxiety, suicidal ideation, non-suicidal self-injurious behavior), and social functioning (school bully victimization, and school bully perpetration). Logistic regression models were used to estimate the associations with ED behaviors, using the heterosexual orientation as the reference group as they are the majority.ResultsCompared to female adolescents, male adolescents reported lower anxiety symptoms (t = − 12.39, p < 0.001, Cohen’s d = − 0.233), were more likely to be the perpetrator of school bullying (χ2 = 190.61, p < 0.001, φ = 0.129), and reported a lower likelihood of taking dietary restriction (χ2 = 290.08, p < 0.001, φ = 0.160). Overall, the prevalence of dietary restriction presented sex disparities. Adolescents who reported no sexual attraction were less likely to engage in ED behaviors. Using heterosexual orientation as the reference group, the group who reported no sexual attraction was associated with lower risk in dietary restriction and purging in both male and female adolescents. Using the heterosexual orientation as the reference group, female sexual minority groups were at high risk of ED behaviors, with bisexual orientation and gay/lesbian orientation having a higher likelihood of engaging in objective binge eating.ConclusionsThe results revealed significant sex and sexual orientation differences of ED behaviors. The study suggests that adolescents is a period of sexuality development and could be critical for understanding adolescents’ eating behaviors. It is important to guide adolescents to healthy eating during their development and considerations should be made by clinicians when creating interventions for ED behaviors among the different sex and sexual orientation groups.

Sexual Orientation Disparities in Depression and Substance Use Among Adults: Results from the Brazilian National Health Survey 2019.

Purpose: We compared the prevalence of depression, hazardous alcohol use, daily tobacco use, and hazardous alcohol and tobacco use (HATU) by sexual orientation and sex among Brazilian adults. Methods: Data were obtained from a national health survey conducted in 2019. This study included participants aged 18 years and older (N = 85,859). Adjusted prevalence ratios (APRs) and confidence intervals were estimated using Poisson regression models stratified by sex to examine the association between sexual orientation, depression, daily tobacco use, hazardous alcohol use, and HATU. Results: After controlling for the covariates, gay men showed a higher prevalence of depression, daily tobacco use, and HATU compared with heterosexual men (APR ranged from 1.71 to 1.92). Furthermore, bisexual men showed a higher prevalence (almost three times) of depression compared with heterosexual men. Lesbian women showed a higher prevalence of binge and heavy drinking, daily tobacco use, and HATU compared with heterosexual women (APR ranged from 2.55 to 4.44). Among bisexual women, the results were significant for all analyzed outcomes (APR ranged from 1.83 to 3.26). Conclusions: This study was the first to use a nationally representative survey to assess sexual orientation disparities related to depression and substance use by sex in Brazil. Our findings highlight the need for specific public policies aimed at the sexual minority population and for greater recognition and better management of these disorders by health professionals.

Violent victimization at the intersections of sexual orientation, gender identity, and race: National Crime Victimization Survey, 2017-2019.

Prior research has found that experiences with violence in the U.S. differ across individual demographic characteristics, including race, gender, and sexual orientation. However, peer reviewed studies have yet to examine the relationship between the intersections of race, gender, and sexual orientation, victimization risk, and characteristics of victimization. We use data from three years (2017-2019) of the National Crime Victimization Survey, the primary source of information on criminal victimization in the United States, to examine victimization at the intersection of sexual orientation, gender, and race/ethnicity. We test whether non-Hispanic Black, Hispanic, and non-Hispanic White sexual and gender minority (SGM) persons aged 16 or over are victimized at greater rates than their non-SGM counterparts and assess whether there are differences between sexual minority females and males of each racial group. We further document characteristics of victimization such as reporting to the police by SGM status and race or ethnicity. We find that SGMs are disproportionately more likely to be victims of violent crime than non-SGM people, and these disparities are present across the assessed racial and ethnic groups (non-Hispanic Black odds ratio [OR] = 3.3, 90% CI [CI] = 1.36, 5.16; Hispanic OR = 4.5, CI = 2.25, 6.71; non-Hispanic White OR = 4.8, CI = 2.25, 6.71). However, sexual orientation disparities are statistically distinguishable for lesbian or bisexual (LB) non-Hispanic White and Hispanic females but not for non-Hispanic Black LB females. Among LB females, the overall differences in victimization were primarily driven by bisexual respondents. We further find racial and ethnic differences among SGM victims in the likelihood of having the victimization reported to the police, in the utilization of community (non-police) resources, and in other aspects of victimization experiences, such as whether arrests occurred or in the suspicion that the violent incident was a hate crime. Our findings raise indicate a complex picture of how sexual orientation, gender identity, sex, and race and ethnicity interact in victimizations and their characteristics that should be further explored.

Clinical psychological science must move beyond documenting disparities in LGBTQ health toward eliminating them.

Psychology and other disciplines have exceptionally documented sexual orientation and gender identity disparities in mental and physical health outcomes with psychological antecedents. Research on sexual and gender minority (SGM) health has seen impressive growth, including the launch of dedicated conferences, journals, and designation as a disparity population for U.S. federal research purposes. From 2015 to 2020, the number of SGM-focused research projects funded by the U.S. National Institutes of Health (NIH) increased by 66.1% (cf. 21.8% for all NIH projects). SGM health research has expanded beyond HIV (73.0% of NIH's SGM projects in 2015 down to 59.8% in 2020) into other domains, such as mental health (41.6%), substance use disorders (23%), violence (7.2%), and transgender (21.9%) and bisexual (17.2%) health. Yet, only 8.9% of projects were clinical trials testing interventions. The need for more research on later stages in the translational research spectrum (i.e., mechanisms, intervention, implementation) to eradicate SGM health disparities is the focus of our Viewpoint article. First, research to eliminate SGM health disparities must move toward multilevel interventions aimed at cultivating health, wellbeing, and thriving. Second, research to test how psychological theories apply to SGM people can inform new theories or extend existing ones, which can spur new areas of inquiry. Third, translational SGM health research would benefit from a developmental lens to identify protective and promotive factors across the life span. Finally, using mechanistic findings to inform, develop, disseminate, and implement interventions to reduce SGM health disparities is crucial at this time.

Women work-force in Agriculture and Rural Development: Issues and Challenges

The ILO assesses those rural women include a fourth of the total populace. Ladies additionally make up 41% of the world's rural workforce, a proportion which ascends to 49 percent for low pay nations. Rustic ladies fill in as ranchers, breadwinners and business people. They address a significant portion of the agribusiness labor force. Their social and financial strengthening can intensely affect usefulness and agribusiness drove development. Orientation disparities in the rural area are critical however hard to evaluate. As ladies are gathered in both neglected consideration and house hold work and their job in resource cultivating is regularly unremunerated, their commitment to the country economy is broadly underrated. Ladies from neighborhood, native and ancestral networks are regularly caretakers of conventional information that is key for their networks' occupations, versatility and culture. Their commitments are exceptional and essential particularly with regards to normal assets the executives, farming and ranger service areas that are basic for both moderation of, and variation to environmental change. Country ladies are gathered in low-gifted, low efficiency, and low or neglected positions with long working hours, helpless working conditions and restricted social assurance. They are bound to fill in as neglected contributing relatives which implies their work is to a great extent unnoticed or underestimated. They are most dynamic in the casual rustic economy and are definitely more outlandish than men to take part in provincial compensation business (both horticultural and non-rural). Whenever they take care of business for compensation, rustic ladies are bound to be utilized in low maintenance, occasional, and time-and work serious exercises. Present survey examination attempting to uncover the condition of ladies work-power in rural regions or semi-rural portions of the country. Paper is likewise zeroing in on the issues like Creating fair positions, business venture preparing and admittance to back, safeguarding provincial ladies from unsuitable types of work, upgrading social insurance, guaranteeing their voices are heard and shutting the portrayal hole are key components required for extraordinary activity.

Binocular viewing geometry shapes neural processing of slanted planes: Results from theoretical V1 modeling and human psychophysics

An important component of real-world scene perception is the estimation of 3D surface orientation (slant and tilt). However, neither the neural circuits that compute 3D orientation nor the supporting computations have been fully uncovered. To help address that gap, we apply a projective geometry framework to the study of both the neural processing and perception of 3D orientation, building on recent work that suggests the mapping of the 3D environment onto the two retinae shapes both the tuning of neurons in area MT to motion-in-depth and corresponding patterns of perceptual errors in human psychophysics (Bonnen et al., 2020). The projection of slanted planes results in interocular disparities in retinal orientation, and interestingly, binocular V1 neurons can have different monocular orientation preferences (Bridge & Cumming, 2001), which could make them sensitive to orientation disparities. Therefore, we have constructed an encoding model that predicts responses of binocular V1 neurons to the orientation disparities produced by a stimulus plane with varying slant, given each theoretical neuron’s monocular orientation preferences and ocular dominance level. The resulting slant tuning curves are noncanonical in shape, do not tile slant evenly, and are strongly affected by viewing distance. Notably, at greater viewing distances, extreme slants (beyond approximately +/- 70 degrees) are encoded by steep portions of the curves, but moderate and low slants are encoded by relatively flat portions. As expected based on those observations, our model population decoder performs best at extreme slants, and performance degrades as slant approaches zero and as viewing distance increases. We additionally observed these patterns in human perceptual performance on a slant discrimination task. These results support the theory that the neural processing of 3D scene components is shaped by projective geometry and represent a step toward advancing understanding of the computations supporting 3D orientation perception.

A Nationally Representative Study of Sexual Orientation and High-Risk Drinking From Adolescence to Young Adulthood

PurposeTo determine whether peer drunkenness, parental knowledge about their adolescent's whereabouts and behaviors, and depressive symptoms contribute to sexual orientation disparities in high-risk drinking behaviors; if they do, they would be potential intervention targets. MethodsLongitudinal survey data from 2,051 adolescents who participated in the NEXT Generation Health Study were analyzed. Latent growth curve and longitudinal path analyses were used to test for indirect effects linking sexual orientation in 11th grade (3.4% males and 8.4% females were sexual minorities) to past 30-day heavy episodic drinking (HED) over 6 years and past year high-intensity binge drinking at 4 years after high school. ResultsSexual minority males were not more likely to engage in high-risk drinking than heterosexual males. In contrast, sexual minority females were more likely than heterosexual females to engage in HED when they were in 11th grade (Odds Ratio = 2.83, 95% confidence interval = 1.43, 5.61), in part because of lower parental knowledge. Sexual minority females also had higher depressive symptoms during the transition from adolescence to young adulthood, which in turn was associated with greater risk of high-intensity binge drinking in young adulthood. Peer drunkenness was a strong risk factor for HED and high-intensity binge drinking among both males and females. DiscussionSexual minority females reported lower levels of parental knowledge during adolescence and higher levels of depressive symptoms during the transition to young adulthood than heterosexual females. Both factors were associated with high-risk drinking behavior, suggesting developmentally sensitive opportunities to mitigate sexual orientation disparities in high-risk drinking.

Same-Sex Marriage and Common Mental Health Diagnoses: A Sibling Comparison and Adoption Approach

ABSTRACT We aimed to test whether the association between same-sex marriage and common mental health diagnoses was explained by shared genetic and environmental familial influences using sibling comparison and adoption analyses. For the sibling comparison analysis, participants (1,177,712 men and 1,266,917 women) were individuals born in Sweden between 1932 and 1994 and had ever been recorded as married (in opposite-sex or same-sex marriages). For the adoption analysis, participants were 147,164 and 1,298 female–female full sibling and adoptive sibling pairs, respectively. Based on medical records, prescribed medication, and death certificates, depression, substance abuse, and suicide (completed and attempted) from age 18 years were identified. For both sexes, being in a same-sex marriage was associated with greater risk of depression, substance abuse, and suicide, compared with being in an opposite-sex marriage. Controlling for shared familial confounding reduced this difference by less than 20% in magnitude, but overall mental health disparities for individuals in same-sex marriages remained statistically significant. Among women, only the genetic correlation between same-sex marriage and depression was statistically significant (r = .33). Same-sex marriage, as a proxy for sexual orientation, was associated with increased risk of certain mental health diagnoses and shared familial confounding explained a small component of this association, depending on the diagnosis. The findings indicate that sexual orientation disparities in mental health outcomes may involve unmeasured factors, and a relatively small proportion should be considered that may be due to shared familial confounding relevant to both sexual orientation and psychopathology.

Sexual orientation and mental health disparities in US pre-teens: A longitudinal mediation study

Abstract Background Sexual minority children are at increased risk for psychopathology compared to their heterosexual peers, but longitudinal studies are needed to determine whether sexual minority identification precedes (rather than co-occurs with) mental health disparities and what may drive these disparities during childhood. The current study examined the longitudinal associations between sexual orientation and mental health over two years in a cohort of U.S. pre-teens with two potential mediators (increased social problems and decreased perceived school safety). Methods We used data from Waves 1-3 (2016-2020) of the U.S. Adolescent Brain Cognitive Development study. Multiple linear regression and auto-regressive cross-lagged mediation models were used to examine longitudinal associations and mediation. Analyses accounted for customized sampling weights to correct for attrition and missing data. Results The analytic sample included 5,574 children (46.0% assigned female at birth, 55.1% non-Hispanic White). Across waves, beginning to identify as gay/bisexual (0.6-2.7% of sample) was associated with increased internalizing and externalizing problems, and consistently identifying as gay/bisexual (3.4-5.0% of sample) with increased internalizing problems, compared to consistently identifying as heterosexual. For those who consistently identified as gay/bisexual, the widening disparities in internalizing problems were partially explained by increased social problems and decreased perceived school safety. Conclusions The health disparities affecting sexual minority children include internalizing and externalizing problems, and are partially explained by increased social problems and decreased perceived school safety. These findings demonstrate that sexual minority identification precedes increases in mental health problems relative to heterosexual children, driven by peer difficulties and feelings of unsafety at school experienced by sexual minority children.

Three Dimensional Printing of Bioinspired Crossed-Lamellar Metamaterials with Superior Toughness for Syntactic Foam Substitution.

Biological materials such as conch shells with crossed-lamellar textures hold impressive mechanical properties due to their capability to realize effective crack control and energy dissipation through the structural synergy of interfacial modulus mismatch and lamellar orientation disparity. Integrating this mechanism with mechanical metamaterial design can not only avoid the catastrophic post-yield stress drop found in traditional architectural materials with uniform lattice structures but also effectively maintain the stress level and improve the energy absorption ability. Herein, a novel bioinspired design strategy that combines regional particularity and overall cyclicity is proposed to innovate the connotation of long-range periodicity inside the metamaterial, in which the node constraint gradient and crossed-lamellar struts corresponding to the core features of conch shells are able to guide the deformation sequence with a self-strengthening response during compression. Detailed in situ experiments and finite element analysis confirm that the rotated broad layer stacking can shorten and impede the shear bands, further transforming the deformation of bioinspired metamaterial into a progressive, hierarchical way, highlighted by the cross-layer hysteresis. Even based on a brittle polymeric resin, excellent specific energy absorption capacity [4544 kJ/kg] has been achieved in this architecture, which far exceeds the reported metal-based syntactic foams for two orders of magnitude. These results offer new opportunities for the bioinspired metamaterials to substitute the widespread syntactic foams in specific applications required for both lightweight and energy absorption.

Neuroticism and Sexual Orientation-Based Victimization as Mediators of Sexual Orientation Disparities in Mental Health.

This study tested whether elevated risk of poorer mental health outcomes among nonheterosexual adolescents compared with heterosexual adolescents is plausibly explained by neuroticism and sexual orientation-based victimization. The Millennium Cohort Study, a large British prospective birth cohort, was used (4566 heterosexual boys, 77 bisexual boys, 129 homosexual boys, 96 asexual boys, 4444 heterosexual girls, 280 bisexual girls, 158 homosexual girls, and 182 asexual girls). We analyzed the following measures assessed at age 17years: sexual orientation based on sexual attraction, neuroticism, sexual orientation-based victimization, self-harm attempts, and psychological well-being. Mediation analysis was undertaken separately by sex and yielded the following statistically significant findings: for both sexes, we found that bisexual and homosexual adolescents scored higher than heterosexual adolescents on neuroticism; for both sexes, bisexual and homosexual adolescents reported more negative psychological well-being scores and self-harm attempts compared with heterosexual adolescents, with total effects (standardized regression coefficients) ranging from .58 to .91; those associations were mediated through sexual orientation-based victimization and neuroticism scores, with the indirect effects (standardized regression coefficients) through sexual orientation-based victimization and neuroticism scores ranging from .09 to .26 and .16 to .55, respectively. Asexual adolescents did not differ significantly from their heterosexual counterparts in psychological well-being and self-harm attempts, with the total effects ranging from -.02 to .21. Sexual orientation-based victimization and neuroticism may both contribute to the sexual orientation-related disparities in psychological well-being and self-harm attempts. However, neuroticism appears to the more powerful factor.

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

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. 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. 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. 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.
