Objectives: Examine very short sleep among adolescents across multiple intersecting social positions and experiences of sexual orientation-based bullying and cyberbullying in two statewide samples.
Methods: A harmonization of two large statewide school-based datasets from grades 9-12 (2019 Minnesota Student Survey, and 2018-2019 California Healthy Kids Survey) was utilized for the analysis (N = 379,710). Exhaustive chi-square automatic interaction detection (an approach for quantitative intersectionality research) explored variability in very short sleep (≤5 hours/night) among adolescents from multiple intersecting social positions (race/ethnicity, gender identity, sexual orientation, and sex assigned at birth), grade, state, and two types of bullying experiences (sexual orientation-based bullying and cyberbullying).
Objective: This study aimed to examine asthma disparities at the intersection of four sociodemographic characteristics, inhaled substance use, and bias-based bullying as metrics of stigma. We hypothesized that high prevalence groups for asthma would be those with marginalized social positions and those reporting bullying experiences, independent of inhaled substance use.
Method: The analytic sample ( = 90,367) included eighth, ninth, and 11th grade students who participated in the 2022 Minnesota Student Survey.
Purpose: Few reports include more than 1-2 social identities when examining organized sport and physical activity (PA) participation among adolescents. We used a quantitative intersectional approach to examine disparities in adolescent sport and PA lesson participation.
Methods: Ninth and 11th grade 2022 Minnesota Student Survey participants (N = 62,940) self-reported social identities and team sport and PA lessons.
Introduction: Globally 38.9 million children under age 5 have overweight or obesity, leading to type 2 diabetes, cardiovascular complications, depression, and poor educational outcomes. Obesity is difficult to reverse and lifestyle behaviors (healthy or unhealthy) can persist from 1.

This study examines disparities in consistent condom use, HIV testing, and PrEP awareness and use across assigned sex, gender identity, sexual orientation, and racial/ethnic identity in a large sample of sexually active LGBTQ+ youth (mean age = 16.5) who completed the 2022 LGBTQ National Teen Survey.

The current study assessed stigma experiences from peers at school, self-esteem, LGBTQ pride, and overlapping social positions as they relate to disordered eating behaviors among LGBTQ adolescents.
Method: Participants included 11,083 adolescents (M = 15.
Purpose Of Review: To synthesize differences in familial negative weight talk and health-related correlates across gender identities and to highlight gaps relevant to the unique experiences and health correlates of boys and transgender and gender diverse youth.
Recent Findings: Most of the studies included in this review observed no difference by gender in familial negative weight talk health correlates. Gender biases in existing measures, however, may have contributed to underreporting of health correlates in boys.
This study examines adolescents' self-reported school-based developmental assets and four intersecting social positions as they relate to prevalence of bullying involvement. Participants were 80,456 ninth and 11th grade students who participated in the 2019 Minnesota Student Survey (30.2% youth of color; 11% lesbian/gay/bisexual/pansexual/queer/questioning; 2.

To address this gap, this study explored the well-being of youth at the intersection of ethnic, racial, sexual, and gender identities in relation to mental health and bullying. Data were from a U.

Participants were 14,968 sexually active 9th and 11th grade students surveyed as part of the 2019 Minnesota Student Survey (15% lesbian/gay/bisexual/queer/pansexual/questioning [LGBQ] and/or transgender/gender diverse [TGD] or gender questioning). Exhaustive Chi-square Automatic Interaction Detection analysis was used to identify experiences (i.

The current study compared the prevalence and psychosocial correlates of family-based weight stigma among adult members of a weight-management program living in Australia, Canada, France, Germany, the UK, and the US.
Methods: Participants (N = 8100 adults who reported having ever experienced weight stigma; 95% female; 94% White) completed an identical online survey in their country's dominant language that assessed their experiences of weight stigma from 16 different family member sources, as well as internalized weight bias, body image, eating behaviors, perceived stress, and self-rated health.
Critical weight communication between parents and their adolescent children is prevalent and harmful. However, research on adolescent perspectives about parental weight communication is limited. The present mixed-methods study aimed to address this gap using inductive thematic analysis of 1743 adolescents' (M=14.

To inform identity-specific PrEP interventions, this study examined stigma in BSMM's lives relating to intersecting experiences of PrEP stigma. We conducted 32 virtual, semistructured qualitative interviews with BSMM residing in the southeastern United States between February and April 2019.

To identify potential risk and protective factors we examined LGBTQ + college students' disclosure of sexual orientation, gender identity, or both (SOGI) to mothers and fathers, living arrangements (whether or not students lived with mothers and fathers), social support from family and friends, and parent-child relationship quality and their association with stress, depressive symptoms, anxiety symptoms, and problem drinking during the pandemic. LGBTQ + college students ( = 366; = 20.

Here we describe a mechanistic link between Na/K-ATPase (NKA) inhibition and activity of the immune checkpoint protein indoleamine-pyrrole 2',3'-dioxygenase 1 (IDO1). We found that IDO1 was necessary and sufficient for production of kynurenine, a downstream tryptophan metabolite, in cancer cells.

Supplementing contact interventions with social-cognitive/emotional approaches may, instead, help facilitate positive contact.

In Experiment 1, rats were trained in an appetitive conditioning task with either a biconditional or a patterning discrimination using relatively brief CSs (10s) and differential outcomes as USs. In this study, rats learned the positive patterning task before they had learned negative patterning, and the biconditional task was the most difficult.

Objective: To investigate the effect of aging on phase transformation and mechanical properties of yttria-tetragonal zirconia polycrystal (Y-TZP).
Materials And Methods: Fully-sintered Y-TZP slabs, IPS E-max ZirCAD (ZC - Ivoclar) and Z-5 ceramic (Z5 - C5 Medical Werks), were artificially aged in autoclave for: 0, 30, 60 or 90min. Flexural strength (FS), crystalline changes (X-ray diffraction analysis - XRD) and surface topography were analyzed.
Road tunnels act like large laboratories; they provide an excellent environment to quantify atmospheric particles emission factors from exhaust and non-exhaust sources due to their known boundary conditions. Current work compares the High Volume, Dichotomous Stacked Filter Unit and Partisol Air Sampler for coarse, PM10 and PM2.5 particle concentration measurement and found that they do not differ significantly (p = 95%).
