The Role of Individual Discrimination and Structural Stigma in the Mental Health of Sexual Minority Youth.

OBJECTIVE: Sexual minority (SM) youth experience a greater mental health burden compared with their heterosexual peers. This study aimed to characterize mental health disparities among SM compared with non-SM youth, test main and interactive associations of SM identity and stressors targeting SM youth at the individual level (interpersonal SM discrimination) and structural level (state-level structural SM stigma) with youth mental health, and explore the contribution of interpersonal SM discrimination to the mental health burden of SM youth. METHOD: Participants included 11,622 youth (ages 9-13; 47.6% assigned female at birth) from the Adolescent Brain Cognitive Development (ABCD) Study. Linear mixed-effects models tested main and interactive associations of SM identity, interpersonal SM discrimination, and structural SM stigma with mental health measures (self-reported overall psychopathology, suicidal ideation, and suicide attempts), adjusting for demographics and other interpersonal stressors not specific to SM (other discrimination types, peer victimization, and cyberbullying). Longitudinal mediation models tested whether interpersonal SM discrimination mediated the associations between SM identity and mental health measures. RESULTS: SM youth (n = 1,051) experienced more interpersonal SM discrimination and overall psychopathology compared with their non-SM peers (n = 10,571). Adjusting for demographics, there were significant associations (main effects) of interpersonal SM discrimination and structural SM stigma with overall psychopathology. When further adjusting for other non-SM-related stressors, the main effect of structural SM stigma was no longer significant. Interpersonal SM discrimination was also significantly associated with suicidal ideation and attempt, accounting for demographics, while structural SM stigma was not. Accounting for both demographics and other non-SM stressors, there was a significant interaction between SM identity and structural SM stigma in association with psychopathology (p = .02), such that, compared with their peers, SM youth showed a greater association between structural SM stigma and psychopathology. Longitudinal mediation revealed that interpersonal SM discrimination was a significant mediator explaining approximately 10% to 15% of the variance of the pathways between SM identity and all mental health outcomes. CONCLUSION: Results delineate contributions of interpersonal discrimination and structural stigma targeting SM youth to their heightened mental health burden in early adolescence. These findings underscore the need to address microlevel and macrolevel SM discrimination and structural stigma when caring for this population.

Allostatic load in early adolescence: gene / environment contributions and relevance for mental health.

Background: Allostatic load is the cumulative "wear and tear" on the body due to chronic adversity. We aimed to test poly-environmental (exposomic) and polygenic contributions to allostatic load and their combined contribution to early adolescent mental health. Methods: We analyzed data on N = 5,035 diverse youth (mean age 12) from the Adolescent Brain Cognitive Development Study (ABCD). Using dimensionality reduction method, we calculated and overall allostatic load score (AL) using body mass index [BMI], waist circumference, blood pressure, blood glycemia, blood cholesterol, and salivary DHEA. Childhood exposomic risk was quantified using multi-level environmental exposures before age 11. Genetic risk was quantified using polygenic risk scores (PRS) for metabolic system susceptibility (type 2 diabetes [T2D]) and stress-related psychiatric disease (major depressive disorder [MDD]). We used linear mixed effects models to test main, additive, and interactive effects of exposomic and polygenic risk (independent variables) on AL (dependent variable). Mediation models tested the mediating role of AL on the pathway from exposomic and polygenic risk to youth mental health. Models adjusted for demographics and genetic principal components. Results: We observed disparities in AL with non-Hispanic White youth having significantly lower AL compared to Hispanic and Non-Hispanic Black youth. In the diverse sample, childhood exposomic burden was associated with AL in adolescence (beta=0.25, 95%CI 0.22-0.29, P<.001). In European ancestry participants (n=2,928), polygenic risk of both T2D and depression was associated with AL (T2D-PRS beta=0.11, 95%CI 0.07-0.14, P<.001; MDD-PRS beta=0.05, 95%CI 0.02-0.09, P=.003). Both polygenic scores showed significant interaction with exposomic risk such that, with greater polygenic risk, the association between exposome and AL was stronger. AL partly mediated the pathway to youth mental health from exposomic risk and from MDD-PRS, and fully mediated the pathway from T2D-PRS. Conclusions: AL can be quantified in youth using anthropometric and biological measures and is mapped to exposomic and polygenic risk. Main and interactive environmental and genetic effects support a diathesis-stress model. Findings suggest that both environmental and genetic risk be considered when modeling stress-related health conditions.

COVID-19-related financial strain and adolescent mental health.

Background: The COVID-19 pandemic and associated responses have induced a host of crises worldwide, including an economic recession and a global mental health crisis. The specific effects of recession on youth mental health are understudied. We aimed to examine the mechanisms by which pandemic-related financial strain may affect mental health in a diverse sample of American adolescents. Methods: We analyzed data from the Adolescent Brain Cognitive Development Study (ABCD Study®), a large, longitudinal study of diverse US adolescents which collected data before and during the pandemic (N = 9,720, mean age 12.9 years, 18.2% Black). Linear mixed-effects models tested associations of financial strain (parent-reported household wage loss and youth-reported financial stress) with depressive symptomatology over time, covarying for multiple confounders including pre-pandemic socioeconomic status and psychopathology, and pandemic-related environmental factors. Longitudinal mediation analyses examined potential mechanisms leading from wage loss to youth mental health. Findings: Financial strain was highly prevalent, especially among low-income participants, with >70% of the total sample reporting lost wages. Both wage loss and subjective financial stress were associated with depressive symptomatology over time (Estimate = 0.04, P = 0.014; Estimate = 0.17, P < 0.001; respectively). The association between financial stress and depressive symptomatology was robust to the addition of multiple environmental confounders (Estimate = 0.16, P < 0.001). Both family-level (family conflict) and individual-level (financial stress) factors mediated the relationship between wage loss and depressive symptomatology. Interpretation: The financial effects of COVID-19 (and worldwide responses to it) have taken a significant toll on youth mental health. In families that lost wages, youth-reported financial stress and familial factors mediated the relationship between wage loss and mental health over time. Findings highlight financial stress as a key driver of youth mental health burden and identify familial factors as critical targets for intervention to mitigate mental health risks in periods of economic crises.

Association between Asthma and Suicidality in 9-12-Year-Old Youths.

PURPOSE: Suicidal ideation and attempts in youth are a growing health concern, and more data are needed regarding their biological underpinnings. Asthma is a common chronic inflammatory disorder in youth and has been associated with suicidal ideation and attempts in adolescent and adult populations, but data in younger children and early adolescents are lacking. We wished to study associations of asthma with childhood suicidality considering asthma's potential as a clinically relevant model for childhood chronic immune dysregulation. METHODS: Using data from the Adolescent Brain Cognitive Development (ABCD) Study (n = 11,876, 47.8% female, mean age 9.9 years at baseline assessment and 12.0 years at two-year follow-up), we assessed associations between asthma and suicidal ideation and attempts through baseline to two-year follow-up. RESULTS: Asthma history as defined by parent report (n = 2282, 19.2% of study population) was associated with suicide attempts (SA) (odds ratio (OR) = 1.44, p = 0.01), and this association remained significant even when controlling for demographics, socioeconomic factors, and environmental factors (OR = 1.46, p = 0.028). History of asthma attacks was associated with both suicidal ideation (SI) and SA when controlling for demographics, socioeconomic factors, and environmental factors (OR = 1.27, p = 0.042; OR = 1.83, p = 0.004, respectively). The association of asthma attack with SA remained significant when controlling for self-reported psychopathology (OR = 1.92, p = 0.004). The total number of asthma attacks was associated with both SI and SA (OR = 1.03, p = 0.043; OR = 1.06, p = 0.05, respectively). CONCLUSIONS: Findings suggest an association between asthma and suicidality in early adolescence. Further research is needed to investigate mechanisms underlying this relationship.
