186 Exploring stress and inflammation in young children with type 1 diabetes

Abstract

OBJECTIVES/GOALS: The purpose of this mixed methods project was to gain a comprehensive understanding and generate data on factors, including stress and inflammatory biomarkers, that may negatively impact glycemic levels in children aged 8-12 years with type 1 diabetes (T1D) from underrepresented backgrounds. METHODS/STUDY POPULATION: This study employed a two-phase sequential QUAN -> qual mixed methods design. Children and their parents were recruited from a pediatric endocrinology clinic in the southeastern United States. In phase 1 (n=34), we used quantitative methods to measure perceived stress, diabetes distress, cortisol, inflammation (IL-1b, IL-2; IL-6; IL-8; TNF-a; CRP), and glycemic level (HbA1c). Both children and their parent/guardian completed surveys, and children provided salivary and blood samples to measure cortisol and inflammatory markers. Phase 2 qualitative interviews in a subset (n=20) of children and parent/guardians from phase 1 are ongoing; preliminary findings will be included in the presentation. RESULTS/ANTICIPATED RESULTS: Mean age of children was 10.47 (sd=1.44), 67.6% were male, and 41.2% were black. HbA1c ranged from 6.8%-15% and only 2 (5.8%) children met ADA recommendations for HbA1c of 7% or less. HbA1c was associated with child reports of perceived stress (r = .403, p < .05), but not parent reports of child perceived stress (r = -.011, p > .05). Parent reports of perceived stress and diabetes distress in children were not significantly associated with child self-report of perceived stress (r = .11, p > .05) or diabetes distress (r = .018, p > .05). Exploratory models with PROCESS suggest that cortisol slope and IL-8 moderate the relationship between child’s perceived stress and glycemic control. DISCUSSION/SIGNIFICANCE: Stressors are emerging that are unique to this population and may help highlight disparities in care. While the study is ongoing, findings may help health professionals identify and mitigate stressors in children with T1D to help maintain optimal glycemic levels.
