Adolescence is a period of intensive development in body, brain, and behavior. Potentiated by changes in hormones and neural response to social stimuli, teenagers undergo a process of social ...re-orientation away from their caregivers and toward expanding peer networks. The current study examines how relative relational closeness to peers (compared to parents) during adolescence is linked to neural response to the facial emotional expressions of other teenagers. Self-reported closeness with friends (same- and opposite-sex) and parents (mother and father), and neural response to facial stimuli during fMRI, were assessed in 8- to 19-year-old typically developing youth (
= 40,
age = 13.90 years old,
= 3.36; 25 female). Youth who reported greater relative closeness with peers than with parents showed decreased activation in the dorsolateral prefrontal cortex (dlPFC) during stimulus presentation, which may reflect lessened inhibitory control or regulatory response to peer-aged faces. Functional connectivity between the dlPFC and dorsal striatum was greatest in older youth who were closer to peers; in contrast, negative coupling between these regions was noted for both younger participants who were closer to peers and older participants who were closer to their parents. In addition, the association between relative closeness to peers and neural activation in regions of the social brain varied by emotion type and age. Results suggest that the re-orientation toward peers that occurs during adolescence is accompanied by changes in neural response to peer-aged social signals in social cognitive, prefrontal, and subcortical networks.
•Structural and functional differences found in right fusiform of preterm youth.•Both reduced gray matter and enhanced BOLD signal to faces was found.•A classifier using density, tractography and ...connectivity surpassed 95% accuracy.•Increased BOLD may be compensatory response for gray matter reductions.
Extremely preterm birth has been associated with atypical visual and neural processing of faces, as well as differences in gray matter structure in visual processing areas relative to full-term peers. In particular, the right fusiform gyrus, a core visual area involved in face processing, has been shown to have structural and functional differences between preterm and full-term individuals from childhood through early adulthood. The current study used multiple neuroimaging modalities to build a machine learning model based on the right fusiform gyrus to classify extremely preterm birth status.
Extremely preterm adolescents (n = 20) and full-term peers (n = 24) underwent structural and functional magnetic resonance imaging. Group differences in gray matter density, measured via voxel-based morphometry (VBM), and blood-oxygen level-dependent (BOLD) response to face stimuli were explored within the right fusiform. Using group difference clusters as seed regions, analyses investigating outgoing white matter streamlines, regional homogeneity, and functional connectivity during a face processing task and at rest were conducted. A data driven approach was utilized to determine the most discriminative combination of these features within a linear support vector machine classifier.
Group differences in two partially overlapping clusters emerged: one from the VBM analysis showing less density in the extremely preterm cohort and one from BOLD response to faces showing greater activation in the extremely preterm relative to full-term youth. A classifier fit to the data from the cluster identified in the BOLD analysis achieved an accuracy score of 88.64% when BOLD, gray matter density, regional homogeneity, and functional connectivity during the task and at rest were included. A classifier fit to the data from the cluster identified in the VBM analysis achieved an accuracy score of 95.45% when only BOLD, gray matter density, and regional homogeneity were included.
Consistent with previous findings, we observed neural differences in extremely preterm youth in an area that plays an important role in face processing. Multimodal analyses revealed differences in structure, function, and connectivity that, when taken together, accurately distinguish extremely preterm from full-term born youth. Our findings suggest a compensatory role of the fusiform where less dense gray matter is countered by increased local BOLD signal. Importantly, sub-threshold differences in many modalities within the same region were informative when distinguishing between extremely preterm and full-term youth.
Many transgender adolescents experience clinically elevated anxiety and depression. Testosterone (T), used as a gender affirming treatment, may reduce symptoms of anxiety and depression. We assessed ...the effect of gender affirming T treatment on internalizing symptoms, body image dissatisfaction, and activation patterns within the amygdala-prefrontal cortex circuit in transgender adolescent boys.
Symptoms of generalized anxiety, social anxiety, depression, suicidality and body image dissatisfaction were measured by self-report and brain activation was measured during a face processing task with functional MRI in a group of 19 adolescent transgender boys receiving T treatment and 23 not receiving gonadal hormone treatment (UT).
Severity of anxiety and depression was significantly lower in the T treated group relative to the UT group, along with a trend of lower suicidality. The T group also reported less distress with body features and exhibited stronger connectivity within the amygdala-prefrontal cortex circuit compared to the UT group. Finally, group differences on depression and suicidality were directly associated with body image dissatisfaction, and anxiety symptoms were moderated by amygdala-prefrontal cortex connectivity differences between groups.
T treatment is associated with lower levels of internalizing symptoms among transgender adolescent boys. T is also associated with greater body satisfaction and greater connectivity in a neural circuit associated with anxiety and depression. Satisfaction with body image was found to overlap with the association between T and both depression and suicidality, and amygdala-prefrontal co-activation moderated the role of T on anxiety.
•Testosterone treated transgender youth have reduced internalizing symptoms.•Testosterone associated with improved body image satisfaction in transgender youth.•Testosterone associated with stronger amygdala-prefrontal cortex co-activation.
Transgender/non-binary (TNB) youth are at increased risk for anxiety, depression, and suicidality compared to cisgender youth. Gender affirming hormone therapy (GAHT, i.e., testosterone or estrogen) ...is a standard of care option for TNB youth, and we have recently shown that GAHT (testosterone) in transgender youth assigned a female sex at birth is associated with reductions in internalizing symptomatology. The current analysis explores: 1) whether these benefits are observed in both TNB youth assigned female at birth (TNBAFAB) and TNB youth assigned male at birth (TNBAMAB) and 2) the extent to which body image dissatisfaction and alteration in neural circuitry relate to internalizing symptoms.
The current study is an expansion of a previous publication from our lab that explored the association between gender-affirming testosterone and internalizing symptomatology. While participants in our previous study consisted of 42 TNBAFAB youth, participants in the current study included adolescent TNBAFAB receiving GAHT (n = 21; GAHT+) and not receiving GAHT (n = 29; GAHT-) as well as adolescent GAHT+ TNBAMAB (n = 15) and GAHT- TNBAMAB (n = 17). Participants reported symptoms of trait and social anxiety, depression, suicidality in the past year, and body image dissatisfaction. Brain activation was measured during a face processing task designed to elicit amygdala activation during functional MRI.
GAHT+ TNBAFAB had significantly lower rates of social anxiety, depression, and suicidality compared to GAHT- TNBAFAB. While there were no significant relationships between estrogen and depression and anxiety symptoms, longer duration of estrogen was related to less suicidality. Both testosterone and estrogen administration were related to significantly lower rates of body image dissatisfaction compared to GAHT- youth. No significant differences emerged for BOLD response in the left or right amygdala during the face processing task, however, there was a significant main effect of GAHT on functional connectivity between the right amygdala and the ventromedial prefrontal cortex, such that GAHT+ youth had stronger co-activation between the two regions during the task. Body image dissatisfaction, greater functional connectivity, their interaction effect, and age predicted depression symptomatology and body image dissatisfaction additionally predicted suicidality in the past year.
The current study suggests that GAHT is associated with fewer short-term internalizing symptoms in TNBAFAB than in TNBAMAB, although internalizing symptoms among TNBAMAB may diminish with longer durations of estrogen treatment. Controlling for age and sex assigned at birth, our findings indicate that less body image dissatisfaction and greater functional connectivity between the amygdala and ventromedial prefrontal cortex were both predictors of fewer levels of internalizing symptoms following GAHT.
•Gender-affirming testosterone was associated with fewer internalizing symptoms.•Longer duration of gender-affirming estrogen was related to fewer depressive symptoms.•Body image dissatisfaction and brain connectivity predict current depressive symptoms.•Body image dissatisfaction predicts suicidality in the past year.
The aim of the study was to examine reproductive health attitudes and behaviors related to contraception use, provider counseling, parenthood goals, and fertility preservation (FP) in TNB ...adolescents.
A 24-item survey was administered to 44 TNB adolescents aged 12–19 years.
Contraceptive use was variable even among the 46% who reported sexual activity. Half denied or were unsure if they had been offered options from their provider to prevent sexually transmitted infections, and more than one third denied or were unsure about the offer of pregnancy prevention options. Importantly, the majority did not desire more information about contraceptive options. Few used FP, although many thought their feelings about parenthood may change in the future.
TNB adolescents are at risk for sexually transmitted infections, unplanned pregnancies, and future infertility, yet many do not desire more information about contraception or FP. Tailored counseling strategies should be developed and researched to protect this vulnerable group of youth.
Youths with special healthcare needs face challenges transitioning from pediatric to adult health care. Understanding possible mechanisms contributing to poor healthcare transition could improve ...care. This study explores associations between health literacy (HL), transition readiness, and healthcare utilization.
Youths with special healthcare needs aged 12–18 years were recruited from a Medicaid accountable care organization (2012–2017). Outcome measures included transition readiness (Transition Readiness Assessment Questionnaire), and healthcare utilization (any well-check, hospitalization, emergency department ED visit, or ambulatory sensitive condition ED visit). Multivariate regression analyses examined whether HL (adequate vs. inadequate) predicted outcomes, after adjusting for covariates. Models were then created to examine whether the effect of HL on healthcare utilization was mediated by transition readiness.
Among 417 youths with special healthcare needs, 67.1% reported adequate HL. Relative to inadequate HL, teens with adequate HL had significantly higher average Transition Readiness Assessment Questionnaire-20 scores (β = .34, p < .001). Controlling for covariates, HL was a significant predictor of having an ambulatory sensitive condition ED visit and having any ED visits neared significance. There was a positive transition readiness mediation effect on having an ED visit, with higher transition readiness being associated with higher odds of having any ED visit in the mediation analysis.
HL is independently associated with higher transition readiness and lower ambulatory sensitive condition ED use, but pathways of action require further study.
We aimed to examine the concurrent associations of gender-affirming hormonal interventions (i.e., puberty blockers, testosterone, estrogen), as well as family and friend social support, on ...transgender and nonbinary (TNB) adolescents' reports of anxiety symptoms, depressive symptoms, nonsuicidal self-injury (NSSI), and suicidality. We hypothesized that gender-affirming hormonal interventions and greater social support would be associated with lower levels of mental health concerns.
Participants (n = 75; aged 11–18; Mage = 16.39 years) were recruited for this cross-sectional study from a gender-affirming multidisciplinary clinic. Fifty-two percent were receiving gender-affirming hormonal interventions. Surveys assessed anxiety and depressive symptoms, NSSI and suicidality in the past year, and social support from family, friends, and significant others. Hierarchical linear regression models examined associations between gender-affirming hormonal interventions and social support (i.e., family, friend) with mental health while accounting for nonbinary gender identity.
Regression models explained 15%–23% of variance in TNB adolescents' mental health outcomes. Gender-affirming hormonal interventions were associated with fewer anxiety symptoms (β = −0.23; p < .05). Family support was associated with fewer depressive symptoms (β = −0.33; p = .003) and less NSSI (β = −0.27; p = .02). Friend support was associated with fewer anxiety symptoms (β = −0.32; p = .007) and less suicidality (β = −0.25; p = .03).
TNB adolescents had better mental health outcomes in the context of receiving gender-affirming hormonal interventions and having greater support from family and friends. Findings highlight the important role of quality family and friend support for TNB mental health. Providers should aim to address both medical and social factors to optimize TNB mental health outcomes.
Gender identity is a core component of human experience, critical to account for in broad health, development, psychosocial research, and clinical practice. Yet, the psychometric characterization of ...gender has been impeded due to challenges in modeling the myriad gender self-descriptors, statistical power limitations related to multigroup analyses, and equity-related concerns regarding the accessibility of complex gender terminology. Therefore, this initiative employed an iterative multi-community-driven process to develop the Gender Self-Report (GSR), a multidimensional gender characterization tool, accessible to youth and adults, nonautistic and autistic people, and gender-diverse and cisgender individuals. In Study 1, the GSR was administered to 1,654 individuals, sampled through seven diversified recruitments to be representative across age (10-77 years), gender and sexuality diversity (∼33% each gender diverse, cisgender sexual minority, cisgender heterosexual), and autism status (>33% autistic). A random half-split subsample was subjected to exploratory factor analytics, followed by confirmatory analytics in the full sample. Two stable factors emerged: Nonbinary Gender Diversity and Female-Male Continuum (FMC). FMC was transformed to Binary Gender Diversity based on designated sex at birth to reduce collinearity with designated sex at birth. Differential item functioning by age and autism status was employed to reduce item-response bias. Factors were internally reliable. Study 2 demonstrated the construct, convergent, and ecological validity of GSR factors. Of the 30 hypothesized validation comparisons, 26 were confirmed. The GSR provides a community-developed gender advocacy tool with 30 self-report items that avoid complex gender-related "insider" language and characterize diverse populations across continuous multidimensional binary and nonbinary gender traits.
Public Significance Statement
Calibrated and validated in youth and adults, neurotypical and neurodivergent populations, and a spectrum of gender identities, the Gender Self-Report is a multidimensional gender characterization tool developed for use with diverse populations. Capturing gender profiles through simple, accessible language and characterizing simultaneously nonbinary and binary gender diversity across continuous spectra, the Gender Self-Report is designed for broad research, clinical, and services-based applications.
Executive function (EF) underlies broad health and adaptive outcomes. For transgender youth, navigating gender discernment and gender affirmation demand EF. Yet, factors associated with transgender ...youth EF are unknown. We investigate hypothesized predictors of EF: over-represented conditions among transgender youth (anxiety and depression symptoms, autism spectrum disorder ASD) and gender-affirming care. One-hundred twenty-four transgender 11−21-year-olds participated. Parents/caregivers completed EF and mental health report measures. ASD diagnostics and gender-affirming medication histories were collected. 21 % of non-autistic and 69 % of autistic transgender youth had clinically elevated EF problems. Membership in the gender-affirming hormone treatment group was associated with better EF. ASD, anxiety symptoms, and membership in the long-duration pubertal suppression group were associated with poorer EF. Given the importance of EF skills for multiple outcomes, and the unique and additional EF demands specific to transgender youths’ experiences, EF skill monitoring—and when appropriate, supports—should be considered for transgender youth.
