Sexual Orientation and Gender Identity/Expression in Adolescent Research:Two Decades in Review

There is a long history of research among adolescents who are minoritized and marginalized for their sexual orientation and gender identity/expression (SOGIE). However, it remains unclear how we can best conceptualize and assess SOGIE in adolescence, resulting in different subpopulations and findings across studies. Addressing this issue, we present a narrative literature review of the conceptualization and assessment of SOGIE, and provide recommendations for conceptualizing and operationalizing these concepts. Our review indicated that most research with adolescent populations still almost exclusively assesses isolated dimensions of sexuality and gender (e.g., attraction but not identity). We argue that to make research inclusive and equitable, scholars are required to make clear substantiated decisions and be transparent about the SOGIE dimensions and, thus, subpopulations they represent.</p

Disparities in Perpetrators, Locations, and Reports of Victimization for Sexual and Gender Minority Adolescents

Purpose Sexual and gender minority (SGM) adolescents are more likely to become victims of bullying and harassment than heterosexual, cisgender adolescents, but little is known about the contextual details of these victimization experiences. This study aims to examine by whom and where adolescents are bullied or harassed, to whom adolescents report such victimization, and whether these experiences differ between SGM and heterosexual, cisgender adolescents. Methods Participants in this nationally representative study were 29,879 students (mean age = 14.1) from 136 Dutch middle/high schools across grades 7–12 (14.5% sexual minority, 2.7% gender minority) who completed a survey about their school-based experiences. Results Perpetrators of victimization of SGM students were more often teachers and school staff compared with heterosexual, cisgender adolescents. Furthermore, SGM students experienced victimization in private locations (in the rest- or changing rooms/parking lots, at home), more often than heterosexual, cisgender students. Finally, SGM students felt less safe than their heterosexual, cisgender peers to report these experiences to teachers or parents, and were more likely to report their experiences to the police or the school janitor. SGM students who reported victimization experiences were less likely to receive support: the problems were less often acted on and persisted more often than those of heterosexual, cisgender students. Conclusions SGM adolescents are not only victimized more often, but also by different perpetrators (teachers, other school staff) and in more private places. Their victimization is also less likely to be recognized or acted on by those responsible for adolescent’s safety: teachers or parents

Sexual and Gender Identity-Based Microaggressions:Differences by Sexual and Gender Identity, and Sex Assigned at Birth Among Dutch Youth

Research describes several sexual and gender identity-based microaggressions that sexual and gender minority (SGM) people might experience. We aimed to examine the occurrence of different sexual and gender identity-based microaggressions among SGM youth and to identify differences by sexual and gender identity, and sex assigned at birth. Open-ended questions about daily experiences were coded for 16 types of sexual and gender identity-based microaggressions in two daily diary studies among Dutch SGM youth (Study 1: N = 90, M age = 17.64 SD = 1.78; Study 2: N = 393, M age = 18.36 SD = 2.65). Several types of microaggressions were identified, and there was sizable variability in the reported frequency. Overall, lesbian women and bisexual youth were less likely to report microaggressions than gay youth. Bisexual youth were less likely to report use of heterosexist or transphobic terminology than gay youth and youth assigned male at birth were less likely to report invalidation of LGBTQ identity than youth assigned female at birth. Last, gender minority youth were more likely to report familial microaggressions, invalidation of LGBTQ identity, and threatening behaviors than cisgender youth. Overall, this study provides empirical support using mixed qualitative and quantitative methods for theorized typologies of microaggressions among Dutch SGM youth

Disparities in persistent victimization and associated internalizing symptoms for heterosexual versus sexual minority youth

This study investigated whether lesbian, gay, and bisexual (LGB) adolescents were at higher risk for persistent victim- ization of bullying compared to heterosexual adolescents, and how victimization trajectories were associated with inter- nalizing symptom development across LGB and heterosexual adolescents. Data came from a five-wave study (MageT1 = 11.1 to MageT5 = 22.3; n = 151 LGB; n = 1,275 heterosexual) and informants were adolescents and their par- ents. Adolescents were classified in three victimization trajectories: persistent (5.6%), decreasing (28.1%) or low (66.3%) victimization. LGB adolescents reported more persistent victimization, relative to no (OR = 6.79, 95% CI [3.52, 13.13]) or decreasing victimization (OR = 3.09, 95% CI [1.53, 6.24]), compared to heterosexual peers. Further, persistent victim- ization was more strongly associated with anxiety among LGB than among heterosexual adolescents

Biomass Fuel Use and Cardiac Function in Nepali Women.

BackgroundExposure to household air pollution (HAP) from cooking with biomass fuel affects billions of people. We hypothesized that HAP from woodsmoke, compared to other household fuels, was associated with adverse cardiovascular outcomes, of which there have been few studies.MethodsA cross-sectional study was completed in 299 females aged 40-70 years in Kaski District, Nepal, during 2017-18. All participants underwent a standard 12-lead ECG, ankle and brachial systolic blood pressure measurement, and 2D color and Doppler echocardiography. Current stove type was confirmed by inspection. Blood pressure, height, and weight were measured using a standardized protocol. Hypertension was defined as ≥140/90 mmHg or prior diagnosis. Hemoglobin A1c (HbA1c) was obtained, with diabetes mellitus defined as a prior diagnosis or HbA1C ≥ 6.5%. We used adjusted linear and logistic multivariable regressions to examine the relationship of stove type with cardiac structure and function.ResultsThe majority of women primarily used liquified petroleum gas (LPG) stoves (65%), while 12% used biogas, and 23% used wood-burning cook-stoves. Prevalence of major cardiovascular risk factors was 35% with hypertension, 19% with diabetes mellitus, and 15% current smokers. After adjustment, compared to LPG, wood stove use was associated with increased indexed left atrial volume (β = 3.15, 95% CI 1.22 to 5.09) and increased indexed left ventricular end diastolic volume (β = 7.97, 95% CI 3.11 to 12.83). There was no association between stove type and systemic hypertension, left ventricular mass, systolic dysfunction, diastolic dysfunction, pulmonary hypertension, abnormal ankle-brachial index, or clinically significant ECG abnormalities.ConclusionBiomass fuel use was associated with increased indexed left atrial volume and increased indexed left ventricular diastolic volume in Nepali women, suggesting subclinical adverse cardiac remodeling from HAP in this cross-sectional study. We did not find evidence of an association with hypertension or typical cardiac sequelae of hypertension. Future studies to confirm these results are needed

Characterization of Tn6238 with a New Allele of aac(6′)-Ib-cr

Here, we report that the genetic structure of Tn1331 remained conserved in Argentina from 1989 to 2013 (72 of 73 isolates), with the exception being the plasmid-borne Tn1331-like transposon Tn6238 containing a new aac(6′)-Ib-cr allele recovered from a colistin-resistant Klebsiella pneumoniae clinical isolate. A bioinformatic analysis of aac(6′)-Ib-like gene cassettes suggests that this new aac(6′)-Ib-cr allele emerged through mutation or homologous recombination in the Tn1331 genetic platform. Tn6238 is a novel platform for the dissemination of aminoglycoside and fluoroquinolone resistance determinants.Fil: Quiroga, María Paula. Consejo Nacional de Investigaciones Científicas y Técnicas.
