Overview

Observational study reveals distinct stress reactivity patterns linked to NR3C1 methylation in adolescents, suggesting autonomic differences relate to loneliness without direct epigenetic mediation.

Key Points

To examine whether individual differences in stress reactivity mediate the relationship between NR3C1 gene methylation and loneliness in early adolescence.
Assessed an adolescent cohort (55.45% girls) exposed to a standardized social evaluative stressor using person-centered analyses.
Measured physiological stress reactivity across three markers: salivary cortisol, heart rate (HR), and skin conductance (SC).
Analyzed direct and indirect associations between NR3C1 methylation, physiological stress response subgroups, and self-reported loneliness.
Identified three distinct cortisol response subgroups: hyporesponsive (30.5%), moderate-responsive (44.2%), and hyperresponsive (25.3%).
Higher NR3C1 methylation was associated with a lower probability of belonging to the highest reactivity subgroups for cortisol and HR, and the high mean-level subgroup for SC.
Belonging to the low mean-level SC subgroup was associated with higher loneliness, but NR3C1 methylation showed no direct or indirect association with adolescent loneliness.
