OBJECTIVES/GOALS: Racial discrimination and its associated stress are well-documented contributors to health disparities among African Americans (AA).This feasibility study aimed to acquire methodological insights and build the infrastructure for a subsequent mindfulness interventional study to reduce the effects of racism-based stress. METHODS/STUDY POPULATION: 20 AA participants ( female 12, male 8 )ages 18-50 were enrolled, and clinical data (blood pressure, waist/hip, BMI, lipids, HbA1c, creatinine) for Allostatic Index were collected. Racism-based stress was measured using RBTSSS and the Everyday Discrimination Scale (EDS). Psychometric measures (Coping, resilience, mindfulness, social connection) and sleep (PSQI) were included. Bivariate analysis explored associations between psychological measures and stress biomarkers, supported by Spearman’s correlation analysis. RESULTS/ANTICIPATED RESULTS: Low discrimination (EDS) was associated with a lower Total cholesterol/HDL ratio (2.99 vs. 4.20, p=0.009) and higher HDL (62 vs. 52, p=0.001). Low EDS participants also had better sleep (mean=3, SD=1.33, vs. mean=5.8, SD=3.99, p=0.05*) but reported less coping through drugs and alcohol (p=0.022*) and higher resilience (p=0.047*). Mindfulness negatively correlated to sleep disturbance (r=-0.477 to r=-0.62), coping and resilience. . EDS correlated with overall life stress and drug and alcohol use. Sleep disturbance was negatively associated with social connection (r=-0.569**) and mindfulness. Sleep disturbance and discrimination correlated positively with drug and alcohol use and overall life stress (r=0.52 and r=0.0.59, respectively), while resilience was negatively correlated with sleep (r=-0.45). DISCUSSION/SIGNIFICANCE: Discrimination was associated with increased stress and unfavorable coping, while mindfulness may offer potential benefits for sleep, coping, and resilience. These preliminary findings provide a foundation for further exploring the potential of mindfulness interventions to address the biopsychological impacts of racism-induced stress.
