Residential exposure to deadly gun violence and accelerated biological aging in a national sample of U.S. adolescents
Background: Gun violence is a traumatic and pervasive neighborhood stressor with far-reaching consequences for population health. However, less is known about how gun violence exposure becomes biologically embedded during adolescence, a sensitive period for shaping aging trajectories. We examined whether residential exposure to deadly gun violence is associated with accelerated biological aging in a diverse sample of U.S. adolescents. Methods: Th…
HIV Concealment and Victimization Among Adolescents with HIV (AWH): The Moderating Role of Emotional Social Support
Adolescents with HIV (AWH) often conceal HIV due to stigma and fear of rejection. Stress-buffering and social embeddedness theory suggest that HIV concealment can increase victimization due to a decline in emotional social support (ESS). Understanding the moderating role of ESS between HIV concealment and victimization may help inform interventions to reduce victimization among AWH. A cross-sectional survey including egocentric social network dat…
