U.S. adolescent suicidal behavior and digital media use prevalence have contemporaneously increased this decade in population-level ecological analyses. The purpose of study was to determine whether these two trends are directly associated by using multi-year person-level data test the association year with mediated use. Data were from Youth Risk Behavior Surveillance System (2009-2017), a nationally-representative biennial cross-sectional self-report survey students (N = 72,942). Mediation...
High smoking prevalence and low quit rates among African American adults are well-documented, but poorly understood. We tested a transdisciplinary theoretical model of psychopharmacological-social mechanisms underlying adults. This proposes that nicotine's acute attention-filtering effects may enhance smoking's addictiveness in populations unduly exposed to discrimination, like adults, because nicotine reduces the extent which discrimination-related stimuli capture attention, turn, generate...
Genome-wide association (GWA) genetic epidemiology research has identified several variants modestly associated with brief self-report smoking measures, predominately in European Americans. GWA not applied intensive laboratory-based measures of endophenotypes African Americans-a population disproportionately low quit rates and high tobacco-related disease risk. This study non-Hispanic Americans tested associations 89 previous exploratory GWAs 24 laboratory-derived tobacco withdrawal...
