RESUMO

Transgender and gender diverse (TGD) young adults experience elevated risk for eating disorders (ED), partially due to cissexist discrimination and victimization; less is understood about how socioeconomic determinants contribute to their ED risk. Qualitative data collected from 66 TGD young adults (18-30 years old; 29% self-identified as transgender women, 29% as transgender men, 39% as nonbinary people, and 3% as another gender identity (e.g., mahu)) in eight asynchronous online focus groups explored how socioeconomic determinants in conjunction with other dimensions of identity and lived experience shape disordered eating behavior (DEB) and ED risk. Participants described how economic barriers-including poverty and dependency on others (e.g. parents for health insurance)-and challenges produced by insurance and healthcare systems impeded healthcare access to the detriment of their overall mental health and risk for ED. In addition, participants shared different ways they leveraged financial resources to cope with stress, sometimes in ways that impelled disordered eating behaviors. Finally, participants described how poverty, socioeconomic advantage and disadvantage, and classism compound other systems of oppression (e.g. racism, ableism, weight bias) to adversely impact their general health and ED risk.

RESUMO

Long-acting injectable pre-exposure prophylaxis for HIV prevention (LAI-PrEP) was approved for use in the United States in 2021, yet little is known about perceptions of LAI-PrEP among transgender and nonbinary young adults, a group that faces substantial barriers to HIV prevention. We investigated US transgender and nonbinary young adults' perceptions of and attitudes toward LAI-PrEP and how perceived advantages and disadvantages of LAI-PrEP related to the PrEP continuum of care. We conducted semi-structured interviews with 31 transgender and nonbinary young adults who reported oral PrEP use or were PrEP-eligible. We analyzed responses using both a deductive RADaR approach, to identify LAI-PrEP perceptions relevant to the PrEP continuum of care, and an inductive thematic analysis to explore key themes. In this study, all PrEP-experienced and most PrEP-naïve participants indicated an interest in LAI-PrEP, citing advantages over daily oral medication (e.g., fewer adherence challenges). Three key themes emerged: (1) Some participants linked perceived advantages of LAI-PrEP to experiences with gender-affirming care (e.g., familiarity with needles via hormone use). (2) Participants weighed trade-offs and contextual factors that influenced their LAI-PrEP preferences (e.g., interest contingent on whether location for receiving injection was geographically accessible). (3) Participants envisaged alternative delivery methods that could enhance LAI-PrEP acceptability and uptake (e.g., home injection). HIV prevention programs should incorporate the insights of transgender and nonbinary young adults to ensure that emerging HIV prevention technologies are accessible and responsive to the needs and concerns of people of all gender modalities.

RESUMO

Early adolescence (ages 11-14 years) is a key period for the emergence of body image and eating concerns, and early identification and access to treatment are imperative for positive outcomes. Despite research identifying this critical developmental period, few prevention resources are available for early adolescents. Parents are key players for this age group and important socializing agents. As such, they are well positioned to help youth access resources or support where needed. However, programs to position and involve parents as interventionists are lacking. Our aims are two-fold. First, we review the evidence for the effectiveness of parents as body image interventionists and the existing data regarding parental needs. Second, we provide directions for future research and outline a framework for empowering parents as interventionists, identifying key domains in which parents may play a role in addressing body image and eating concerns among early adolescents. Based on the extent literature, these domains include facilitating engagement with or co-utilizing intervention content to decrease body image and eating concerns in at-risk children, which may also help to increase parents' effectiveness in their efforts to support youth. In addition, parents may deliver content to decrease or reverse risk-factors and early symptoms, or disrupt the early disorder phase of illness. To date, parents constitute an underutilized resource in eating disorder and disordered eating prevention, and efforts should be made to increase the evidence-based strategies to leverage their relationship with at-risk children.

RESUMO

Some researchers and clinicians may feel hesitant to assess sexual orientation and gender-related characteristics in youth surveys because they are unsure if youth will respond to these questions or are concerned the questions will cause discomfort or offense. This can result in missed opportunities to identify LGBTQ+ youth and address health inequities among this population. The aim of this study was to examine the prevalence and sociodemographic patterns of missingness among survey questions assessing current sexual orientation, gender identity and expression (SOGIE), and past change in sexual orientation (sexual fluidity) among a diverse sample of U.S. youth. Participants (N = 4,245, ages 14-25 years; 95% cisgender, 70% straight/heterosexual, 53% youth of color), recruited from an online survey panel, completed the Wave 1 survey of the longitudinal Sexual Orientation Fluidity in Youth (SO*FLY) Study in 2021. Current SOGIE, past sexual fluidity, and sociodemographic characteristics were assessed for missingness. Overall, 95.7% of participants had no missing questions, 3.8% were missing one question, and 0.5% were missing ≥ 2 questions. Past sexual fluidity and assigned sex were most commonly missing. Sociodemographic differences between participants who skipped the SOGIE questions and the rest of the sample were minimal. Missingness for the examined items was low and similar across sociodemographic characteristics, suggesting that almost all youth are willing to respond to survey questions about SOGIE. SOGIE and sexual fluidity items should be included in surveys and clinical assessments of youth to inform clinical care, policy-making, interventions, and resource development to improve the health of all youth.

RESUMO

INTRODUCTION: Weight stigma is widespread and exists across numerous domains including health care, educational institutions, workplaces, mass media, and interpersonal relationships. Weight stigma experienced during the college years may be particularly consequential because the college years are a period of increased vulnerability for the development of mental health concerns. The purpose of the present study was to examine how experiences of weight stigma relate to mental health concerns, including symptoms of eating disorders, anxiety, and depression, among college students. METHODS: Prevalence of interpersonal and anticipated weight stigma was examined among 2,707 students participating in the 2018-2019 and 2019-2020 Healthy Minds Study and tested for differences in prevalence across student characteristics. Logistic regression was used to explore relationships between measures of weight stigma and student mental health. Analyses were conducted in 2021-2023. RESULTS: Interpersonal and anticipated weight stigma were reported by 12.3% and 15.3% of students, respectively. Experiences of interpersonal and anticipated weight stigma were generally lowest among cisgender male students, heterosexual students, those with the fewest financial concerns, and those who did not perceive themselves to be "overweight." Both interpersonal and anticipated weight stigma were associated with elevated odds of high weight concerns, past-month binge eating, past-month purging, high eating disorder risk, moderate/severe anxiety symptoms, and moderate/severe depressive symptoms. CONCLUSIONS: Findings implicate interpersonal and anticipated weight stigma as potential risk factors for a range of mental health concerns. Weight stigma is an under-recognized and under-funded public health problem.

RESUMO

INTRODUCTION: There are documented inequities in eating disorders (EDs) by gender and race/ethnicity, yet, little is known about population-level prevalence of ED risk factors, symptoms, and diagnosis at the intersection of diverse gender and racial/ethnic identities. METHODS: Data from the Healthy Minds Study 2015-2019 (N = 251,310 U.S. university students) were used in a multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA). Participants were nested in 35 intersectional strata given by all combinations of 5 gender and 7 racial/ethnic categories. Multilevel logistic models with participants at level 1 and intersectional strata at level 2 were used to estimate stratum-specific predicted prevalence estimates for self-reported thin-ideal internalization, ED symptoms, and ED diagnosis. The variance partition coefficient (VPC) was calculated to quantify the contextual effect of the strata. RESULTS: There was considerable heterogeneity in the predicted prevalence of our ED outcomes across the strata (e.g., .3%-18.3% for ED diagnoses). There were large disparities in all three outcomes, with transgender participants of color having a higher predicted prevalence than expected based on the additive effects of gender and race/ethnicity. Moderation by race/ethnicity was also apparent, such that racial/ethnic disparities were wider within the cisgender groups relative to the transgender groups. VPCs indicated that ~10% of the total variance in ED outcomes was due to intersectionality between gender and race/ethnicity, over and above variance due to individual-level differences. CONCLUSION: Findings suggest that gender and racial/ethnic disparities in EDs are interrelated, underscoring the need to develop preventive interventions centering health equity. PUBLIC SIGNIFICANCE: Despite evidence that sexism, racism, and cissexism (i.e., anti-transgender prejudice) can impact EDs risk, little research examines the social patterning of EDs at the intersection of diverse gender and racial/ethnic identities. Using data from a sample of 250,000 U.S. university students, this study found that gender and racial/ethnic disparities in eating disorder risk are interrelated, highlighting the need to develop health equity centered preventive interventions.

RESUMO

Transgender and gender diverse (TGD) young adults face higher risk of eating disorder (ED) symptoms than cisgender peers. Evidence-based ED prevention programs exist but must be adapted to meet the needs of diverse TGD populations. We conducted eight asynchronous online focus groups in 2019 with 66 ethnically and gender diverse TGD young adults (18-30 years) living in the United States. Participants were recruited online; groups took place over four consecutive days. We conducted inductive thematic analysis of participant responses to three prompts about ED prevention needs and advice for program developers. Findings fell into three domains. In Domain 1: Developing Program Content, themes included (1.1) need to address multiple dimensions of gender; (1.2) intersectional representation matters; (1.3) limitations of ED research; (1.4) being responsive to trauma. Domain 2: Program Delivery Considerations, included preferences for (2.1) group composition, (2.2) intervention modality, and (2.3) program leadership. Domain 3: Cultivating Affirming Spaces included themes addressing the need for programs to (3.1) create judgment-free environments and (3.2) center lived experience. TGD young adults in this study described a range of needs and recommendations for ED prevention content and delivery, with relevance to clinicians, program designers, and ED prevention advocates.

RESUMO

Blueberries are rich in nutrients and (poly)phenols, popular with consumers, and a major agricultural crop with year-round availability supporting their use in food-based strategies to promote human health. Accumulating evidence indicates blueberry consumption has protective effects on cardiovascular health including vascular dysfunction (i.e., endothelial dysfunction and arterial stiffening). This narrative review synthesizes evidence on blueberries and vascular function and provides insight into underlying mechanisms with a focus on oxidative stress, inflammation, and gut microbiota. Evidence from animal studies supports beneficial impacts on vascular function. Human studies indicate acute and chronic blueberry consumption can improve endothelial function in healthy and at-risk populations and may modulate arterial stiffness, but that evidence is less certain. Results from cell, animal, and human studies suggest blueberry consumption improves vascular function through improving nitric oxide bioavailability, oxidative stress, and inflammation. Limited data in animals suggest the gut microbiome mediates beneficial effects of blueberries on vascular function; however, there is a paucity of studies evaluating the gut microbiome in humans. Translational evidence indicates anthocyanin metabolites mediate effects of blueberries on endothelial function, though this does not exclude potential synergistic and/or additive effects of other blueberry components. Further research is needed to establish the clinical efficacy of blueberries to improve vascular function in diverse human populations in a manner that provides mechanistic information. Translation of clinical research to the community/public should consider feasibility, social determinants of health, culture, community needs, assets, and desires, barriers, and drivers to consumption, among other factors to establish real-world impacts of blueberry consumption.

RESUMO

Although transgender and nonbinary (TNB) people can acquire human papillomavirus (HPV), research examining HPV vaccination in these populations is scarce. TNB individuals experience high levels of gender-related health care discrimination, which may undermine HPV vaccine uptake. Using data from a national online survey (N=716), we found a negative association between gender-related health care discrimination and HPV vaccination among transgender women and nonbinary individuals who were assigned male at birth (AMAB; odds ratio [OR]=0.52; 95% confidence interval [CI]: 0.29-0.93). Addressing gender-related health care discrimination may facilitate HPV vaccination and help prevent HPV-related cancers among transgender women and nonbinary AMAB individuals.

RESUMO

Purpose: Transgender and nonbinary (TNB) populations experience disproportionate rates of sexual assault. Despite evidence from cisgender samples linking sexual assault exposure to body image concerns and disordered eating behaviors, such as weight and shape control behaviors (WSCBs), little is known about these relationships in TNB people. The purpose of this study was to assess associations among past-year sexual assault exposure, body areas satisfaction, body weight esteem, and high-risk WSCBs in a sample of TNB young adults. Methods: A sample of 714 participants completed a cross-sectional online survey. Multivariable linear and logistic models were fit to determine associations between constructs of interest. Natural effects mediation analyses assessed for potential mediation of the relationship between sexual assault and WSCBs by body areas satisfaction and body weight esteem. Analyses were stratified by three gender identity categories. Results: Past-year sexual assault exposure was associated with significantly decreased body areas satisfaction, but only for nonbinary participants. No significant association was found between sexual assault and body weight esteem. Sexual assault was associated with significantly increased risk for WSCBs across gender identity categories. No mediation of these relationships by body areas satisfaction and body weight esteem was observed. Conclusion: Findings support clinical consideration of WSCBs in TNB survivors of sexual assault. Results suggest that multiple factors, including body image and sexual assault, may contribute separately to disordered eating behaviors in TNB young adults.

RESUMO

Middle-aged adults can start to be affected by some arterial diseases (ADs), such as abdominal aortic or popliteal artery aneurysms, lower extremity arterial disease, internal carotid, or renal artery or subclavian artery stenosis. These vasculopathies are often asymptomatic or paucisymptomatic before manifesting themselves with dramatic complications. Therefore, early detection of ADs is fundamental to reduce the risk of major adverse cardiovascular and limb events. Furthermore, ADs carry a high correlation with silent coronary artery disease (CAD). This study focuses on the most common ADs, in the attempt to summarize some key points which should selectively drive screening. Since the human and economic possibilities to instrumentally screen wide populations is not evident, deep knowledge of semeiotics and careful anamnesis must play a central role in our daily activity as physicians. The presence of some risk factors for atherosclerosis, or an already known history of CAD, can raise the clinical suspicion of ADs after a careful clinical history and a deep physical examination. The clinical suspicion must then be confirmed by a first-level ultrasound investigation and, if so, adequate treatments can be adopted to prevent dreadful complications.

RESUMO

BACKGROUND: Young adults who are transgender and/or nonbinary (TNB) experience discrimination, violence, and other social stressors as a result of cissexism, the system of power relations that marginalizes people whose genders diverge from sociocultural expectations for the sex they were assigned at birth. However, variation in TNB young adults' exposure to social stressors across gender groups, particularly specific nonbinary gender groups (e.g., agender, genderqueer), has not been well characterized. METHODS: We analyzed data from an online cross-sectional survey of U.S. TNB young adults (N = 667; ages 18-30 years; 44% White, 24% multiracial, 14% Black, 10% Latinx, 7% Asian, 1% another race/ethnicity), assessing gender non-affirmation; cissexist discrimination, rejection, and victimization; general discrimination; sexual assault victimization; and psychological, physical, and sexual abuse in childhood/adolescence. We used generalized linear models to test for variation in stressors across six gender groups (transgender woman [n = 259], transgender man [n = 141], agender [n = 36], gender fluid [n = 30], genderqueer [n = 51], nonbinary [n = 150]) and compare each group to the full sample. We performed similar analyses among nonbinary gender groups. RESULTS: Exposure to stressors was considerable in all groups. Several stressors (e.g., past-year cissexist discrimination) did not vary significantly by gender group. Compared to the full sample, transgender women reported greater lifetime cissexist rejection and lifetime and past-year cissexist victimization. Compared to the full sample, transgender men and women reported greater lifetime cissexist discrimination and lower past-year gender non-affirmation. No stressors varied significantly across nonbinary gender groups. CONCLUSION: Among TNB young adults, women, men, and nonbinary people experience distinct patterns of some (though not all) stigma-related stressors. Decisions about (dis)aggregating research participants by gender group, or providing gender-tailored services for TNB people, should account for patterning of pertinent stressors. Efforts to eliminate structural cissexism should address intersections with other systems of power relations, including sexism and binary normativity.

RESUMO

OBJECTIVE: Though prevalent, weight-based discrimination is understudied and has been linked to disordered eating behaviors (DEB) among adolescents and adults. Sexual minority populations experience elevated risk of DEB, but little is known about the role of weight discrimination in this elevated risk. METHODS: Participants were 1257 sexual minority women and men (ages 18-31 years) in the US Growing Up Today Study cohort. We examined cross-sectional associations between weight discrimination victimization and three DEB in the past year: unhealthy weight control behaviors, overeating, and binge eating. Generalized estimating equations, adjusted for potential confounders, were used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs). RESULTS: Three in 10 participants (31%) reported weight-based discrimination victimization. Sexual minority young adults who reported weight-based discrimination had greater relative prevalence of unhealthy weight control behaviors (PR [95% CI]: 1.92 [1.35, 2.74]), overeating (3.15 [2.24, 4.44]), and binge eating (3.92 [2.51, 6.13]), compared with those who reported no weight-based discrimination. Associations with overeating and binge eating remained significant after adjusting for BMI. DISCUSSION: The role of weight-based discrimination, and its intersections with other forms of stressors for sexual minority young adults, must be included in efforts to advance eating disorder prevention for this underserved population. PUBLIC SIGNIFICANCE: Three in 10 sexual minority young adults in this study had experienced weight-based discrimination, a common but understudied form of discrimination. Sexual minority young adults who experienced weight-based discrimination were at greater risk of disordered eating behaviors than those who had not experienced weight-based discrimination. These findings suggest that weight-based discrimination may be an important-and preventable-risk factor for disordered eating behaviors among sexual minority young adults.

RESUMO

Transgender and gender diverse (TGD) youth experience significant risk for negative health outcomes, yet few studies exist that address TGD youth's experiences of health care. This paper explores the equitable access and utilization of health care in a sample of TGD youth of diverse gender and racial/ethnic identities. Data for this analysis are from the TGD subsample (n = 1415) of the 2018 Survey of Today's Adolescent Relationships and Transitions (START) Project. We assessed five health care experiences: being insured, having a current health care provider, being out to one's provider, believing your provider was knowledgeable about transgender issues, and barriers to accessing care due to gender identity/expression. We examined the proportion of TGD youth who reported each of these outcomes and within-group differences by gender identity and race/ethnicity using descriptive statistics, logistic regression, and predicted probabilities. When differences were examined by gender identity, barriers to equitable care were consistently more present among transgender females than youth of other gender identities. There were few significant differences by race/ethnicity; however, dual referent models demonstrated barriers to equitable care were particularly evident among Black and Hispanic transgender women. We discuss these findings through the lens of intersectionality and highlight the importance of research and intervention work focused on reducing barriers to equitable care for TGD youth.

RESUMO

Estrogen-deficient postmenopausal women have oxidative stress-mediated suppression of endothelial function that is exacerbated by high blood pressure. Previous research suggests blueberries may improve endothelial function through reductions in oxidative stress, while also exerting other cardiovascular benefits. The objective of this study was to examine the efficacy of blueberries to improve endothelial function and blood pressure in postmenopausal women with above-normal blood pressure, and to identify potential mechanisms for improvements in endothelial function. A randomized, double-blind, placebo-controlled, parallel-arm clinical trial was performed, where postmenopausal women aged 45-65 years with elevated blood pressure or stage 1-hypertension (total n = 43, endothelial function n = 32) consumed 22 g day-1 of freeze-dried highbush blueberry powder or placebo powder for 12 weeks. Endothelial function was assessed at baseline and 12 weeks through ultrasound measurement of brachial artery flow-mediated dilation (FMD) normalized to shear rate area under the curve (FMD/SRAUC) before and after intravenous infusion of a supraphysiologic dose of ascorbic acid to evaluate whether FMD improvements were mediated by reduced oxidative stress. Hemodynamics, arterial stiffness, cardiometabolic blood biomarkers, and plasma (poly)phenol metabolites were assessed at baseline and 4, 8, and 12 weeks, and venous endothelial cell protein expression was assessed at baseline and 12 weeks. Absolute FMD/SRAUC was 96% higher following blueberry consumption compared to baseline (p < 0.05) but unchanged in the placebo group (p > 0.05), and changes from baseline to 12 weeks were greater in the blueberry group than placebo (+1.09 × 10-4 ± 4.12 × 10-5vs. +3.82 × 10-6 ± 1.59 × 10-5, p < 0.03, respectively). The FMD/SRAUC response to ascorbic acid infusion was lower (p < 0.05) at 12 weeks compared to baseline in the blueberry group with no change in the placebo group (p > 0.05). The sum of plasma (poly)phenol metabolites increased at 4, 8, and 12 weeks in the blueberry group compared to baseline, and were higher than the placebo group (all p < 0.05). Increases in several plasma flavonoid and microbial metabolites were also noted. No major differences were found for blood pressure, arterial stiffness, blood biomarkers, or endothelial cell protein expression following blueberry consumption. These findings suggest daily consumption of freeze-dried blueberry powder for 12 weeks improves endothelial function through reduced oxidative stress in postmenopausal women with above-normal blood pressure. The clinical trial registry number is NCT03370991 (https://clinicaltrials.gov).

RESUMO

OBJECTIVES: To examine fluidity in sexual orientation identity and behavior among cisgender youth. STUDY DESIGN: Data were analyzed from 5 survey waves of the longitudinal US Growing Up with Media Study (2010-2019). Participants were 989 cisgender youth, aged 13-20 years at baseline, who completed online surveys assessing sexual orientation identity and behavior (gender of sexual partners). Amount of change (mobility) and patterns of change across waves were assessed for identity and behavior. RESULTS: Consistently heterosexual was the most common sexual orientation identity (89%-97% for boys, 80%-90% for girls), followed by gay (3%) for boys, and bisexual (8%) for girls. Sexual minority identities increased (3%-11% for boys, 10%-20% for girls) over time, same-gender sexual behavior also increased. Girls had more identity mobility than boys; no gender difference was found for behavior mobility. Movement from heterosexual to a sexual minority identity occurred for 9% of girls and 6% of boys; movement from different-gender sexual behavior to same-gender sexual behavior occurred for 2% of girls and boys. CONCLUSIONS: Findings highlight the need to assess multiple dimensions and patterns of change of youth sexual orientation in research and clinical care. Recognizing and creating space for conversations about changes in sexual identity and behavior over time will help providers accurately and effectively address the health needs of all patients.

RESUMO

BACKGROUND: Identifying sex-related differences/variables associated with 30 day/1 year mortality in patients with chronic limb-threatening ischemia (CLTI). METHODS: Multicenter/retrospective/observational study. A database was sent to all the Italian vascular surgeries to collect all the patients operated on for CLTI in 2019. Acute lower-limb ischemia and neuropathic-diabetic foot are not included. FOLLOW-UP: One year. Data on demographics/comorbidities, treatments/outcomes, and 30 day/1 year mortality were investigated. RESULTS: Information on 2399 cases (69.8% men) from 36/143 (25.2%) centers. Median (IQR) age: 73 (66-80) and 79 (71-85) years for men/women, respectively (p < 0.0001). Women were more likely to be over 75 (63.2% vs. 40.1%, p = 0.0001). More men smokers (73.7% vs. 42.2%, p < 0.0001), are on hemodialysis (10.1% vs. 6.7%, p = 0.006), affected by diabetes (61.9% vs. 52.8%, p < 0.0001), dyslipidemia (69.3% vs. 61.3%, p < 0.0001), hypertension (91.8% vs. 88.5%, p = 0.011), coronaropathy (43.9% vs. 29.4%, p < 0.0001), bronchopneumopathy (37.1% vs. 25.6%, p < 0.0001), underwent more open/hybrid surgeries (37.9% vs. 28.8%, p < 0.0001), and minor amputations (22% vs. 13.7%, p < 0.0001). More women underwent endovascular revascularizations (61.6% vs. 55.2%, p = 0.004), major amputations (9.6% vs. 6.9%, p = 0.024), and obtained limb-salvage if with limited gangrene (50.8% vs. 44.9%, p = 0.017). Age > 75 (HR = 3.63, p = 0.003) is associated with 30 day mortality. Age > 75 (HR = 2.14, p < 0.0001), nephropathy (HR = 1.54, p < 0.0001), coronaropathy (HR = 1.26, p = 0.036), and infection/necrosis of the foot (dry, HR = 1.42, p = 0.040; wet, HR = 2.04, p < 0.0001) are associated with 1 year mortality. No sex-linked difference in mortality statistics. CONCLUSION: Women exhibit fewer comorbidities but are struck by CLTI when over 75, a factor associated with short- and mid-term mortality, explaining why mortality does not statistically differ between the sexes.

RESUMO

PURPOSE: This study examined sociodemographic patterns of retrospective fluidity in sexual orientation identity (i.e., any change from one identity to another) and attractions (i.e., any change in attractions to one or more gender(s)) in a large sample of US youth. METHODS: Participants were 4,087 youth (58% cisgender girls/women, 38% cisgender boys/men, 5% transgender or nonbinary individuals), ages 14-25 years, from across the United States, who were recruited from an online survey panel. Sexual and gender minorities and people of color were oversampled. Participants completed the Wave 1 survey of the longitudinal Sexual Orientation Fluidity in Youth study, which assessed sociodemographic characteristics and retrospective fluidity in sexual orientation identity and attractions. RESULTS: Across the sample, 17% reported a retrospective change in identity and 33% reported a change in attractions. Participants who were most likely to report identity change were in the younger age group (14-17 years), were transgender or nonbinary, had a plurisexual identity (pansexual, queer), and reported attractions to more than one gender. Participants who were most likely to report attraction change were nonbinary, had a plurisexual identity (pansexual, queer, bisexual), and reported attractions to more than one gender. DISCUSSION: This study found retrospective changes in sexual orientation identity and attractions were common in this sample of youth, with the prevalence of these changes differing by sociodemographic characteristics. Results from this study inform future research on adolescent health and have implications for supporting and caring for this age group, for whom sexual fluidity is common.

RESUMO

Recognizing the historical grounding of sexual identity development, we examined the spontaneous narration of the internet's significance among a diverse sample of three distinct birth cohorts of sexual minority adults (n = 36, ages 18-59) in the United States. Thematic analysis revealed two structural barriers and four roles of the internet in sexual identity development. Structural barriers were being in a heterosexual marriage (exclusive to members of the older cohort), and (2) growing up in a conservative family, religion, or community (which cut across cohorts). Roles of the internet included: learning about LGBQ+ identities and sex; watching pornography (which appeared only in narratives of the younger cohort); finding affirming community; and facilitating initial LGBQ+ romantic and sexual experiences (which appeared mostly in narratives of the younger cohort). Most participants who described the internet as playing a role in sexual identity development were members of the younger (ages 18-25) and middle (ages 34-41) cohorts. We discuss how the internet has assumed a unique role in history in the development of sexual minority people. Further, our findings highlight that sexual identity development occurs across the lifespan, and how that process and the roles of the internet vary by generation and structural realities.

RESUMO

BACKGROUND: Sexually transmitted infections (STIs) cause a major burden of disease in the United States (US)-especially among structurally marginalized populations, including transgender and nonbinary people, individuals assigned female at birth (AFAB), Black and Latinx/e individuals, and young adults. Although screening can help detect and prevent STIs, research on STI testing among populations at diverse intersections of multiple forms of structural marginalization, including Black, Latinx/e, and other racially/ethnically minoritized transgender men and nonbinary AFAB US young adults, is extremely scarce. METHODS: We conducted a national cross-sectional online survey of transgender and nonbinary US young adults from February to July 2019. Using Poisson regression, we estimated prevalence ratios (PR) and 95% confidence intervals (CI) for the associations between race/ethnicity-which we conceptualized as a system of structural inequality that shapes individuals' and groups' exposure to racism-and lifetime and past-year STI testing among transgender men and nonbinary AFAB US young adults aged 18-30 years with at least one-lifetime sexual partner (N = 378). RESULTS: Approximately 74% of participants had received an STI test in their lifetime, and, among those, 72% with a past-year sexual partner had been tested for an STI in the last 12 months. We observed no statistically significant association between race/ethnicity and lifetime STI testing among transgender and nonbinary AFAB young adults with a lifetime sexual partner. In contrast, Black (PR = 1.32; 95%: 1.03, 1.68) and Latinx/e (PR = 1.39; 95% CI: 1.11, 1.75) transgender men and nonbinary AFAB young adults who ever received an STI test and had a past-year sexual partner were significantly more likely to have received an STI test in the last 12 months relative to their White counterparts, adjusting for demographic factors. Further adjustment for lifetime STI diagnosis and health insurance status did not appreciably attenuate these observed adjusted differences; however, the adjusted difference in the prevalence of past-year STI testing between Black (but not Latinx/e) and White transgender men and nonbinary AFAB young adults was no longer statistically significant upon further adjustment for educational attainment and employment status, possibly due to small sample sizes. CONCLUSION: The higher adjusted prevalence of past-year STI testing among Black and Latinx/e compared to White transgender men and nonbinary AFAB US young adults may reflect racist and xenophobic sexual stereotypes about Black and Latinx/e people among health care providers and institutions, the history of hyper-surveillance of Black and Latinx/e people by public health institutions in the context of infectious disease containment, and/or agency and resistance among Black and Latinx/e transgender men and nonbinary AFAB young adults with regard to sexual health promotion in the face of multiple compounding systems of oppression.
