The first year of the COVID-19 pandemic constituted a major life stress event for many adolescents, associated with disrupted school, behaviors, social networks, and health concerns. However, pandemic-related stress was not equivalent for everyone and could have been influenced by pre-pandemic factors including brain structure and sleep, which both undergo substantial development during adolescence. Here, we analyzed clusters of perceived stress levels across the pandemic and determined developmentally relevant pre-pandemic risk factors in brain structure and sleep of persistently high stress during the first year of the COVID-19 pandemic. We investigated longitudinal changes in perceived stress at six timepoints across the first year of the pandemic (May 2020–March 2021) in 5559 adolescents (50 % female; age range: 11–14 years) in the United States (U.S.) participating in the Adolescent Brain Cognitive Development (ABCD) study. In 3141 of these adolescents, we fitted machine learning models to identify the most important pre-pandemic predictors from structural MRI brain measures and self-reported sleep data that were associated with persistently high stress across the first year of the pandemic. Patterns of perceived stress levels varied across the pandemic, with 5 % reporting persistently high stress. Our classifiers accurately detected persistently high stress (AUC > 0.7). Pre-pandemic brain structure, specifically cortical volume in temporal regions, and cortical thickness in multiple parietal and occipital regions, predicted persistent stress. Pre-pandemic sleep difficulties and short sleep duration were also strong predictors of persistent stress, along with more advanced pubertal stage. Adolescents showed variable stress responses during the first year of the COVID-19 pandemic, and some reported persistently high stress across the whole first year. Vulnerability to persistent stress was evident in several brain structural and self-reported sleep measures, collected before the pandemic, suggesting the relevance of other pre-existing individual factors beyond pandemic-related factors, for persistently high stress responses. • The paper reports findings from the ABCD study® on U.S. youth across the first COVID-19 pandemic year: May 2020 – March 2021. • 5% of adolescents reported persistently high stress levels during the first year of the pandemic. • Persistent stress was linked to pre pandemic brain structure, sleep difficulties, and more advanced puberty stages. • The findings inform preventive and treatment approaches for persistent stress during major life stress events like pandemics.

Globally, as medical and mental health associations increasingly have expressed support for the gender-affirming care model for trans and gender expansive youth, this model has been paradoxically banned across the United States. Ban proponents have deemed the science behind gender-affirming care to be dangerously uncertain. Examining the first gender-affirming care ban for minors, Arkansas's Save Adolescents from Experimentation (SAFE) Act of 2021, we addressed the following two questions: 1) who are the scientists, clinicians, and political organizations that promote SAFE and similar bans?; and 2) what are the scientific arguments they make to defend SAFE in federal court? First, we developed a typology of the various "agents of scientific uncertainty" behind these bans, drawing on literature from the sociology and history of science and medicine as well as the political economy of scientific doubt. Second, we created and qualitatively analyzed a dataset featuring 375 unique citations referenced throughout federal litigation over SAFE to identify these agents of scientific uncertainty's arguments. We sorted these arguments into eight categories, which reveal how agents distorted scientific evidence and exaggerated real uncertainties and risks in gender-affirming care. This case study establishes a frame for understanding the growing prevalence and legal impact of scientific arguments against gender-affirming care. • Gender-affirming care (GAC) for minors has been increasingly banned in the U.S. • Despite growing medical support, ban proponents label GAC dangerously uncertain. • The paper outlines the scientists, clinicians, and political groups defending bans. • It also describes the scientific arguments used in litigation defending bans. • Scientific uncertainty arguments have been successful at unduly restricting GAC.
