Background Comorbidity between depression and type 2 diabetes is thought to arise from the joint effects of psychological, behavioral, biological processes. Studies monozygotic twins may provide a unique opportunity for clarifying how these processes inter-relate. This paper describes rationale, characteristics, initial findings longitudinal co-twin study aimed at examining biopsychosocial mechanisms linking risk in mid-life. Methods Participants Mood Immune Regulation Twins (MIRT) Study were recruited Mid-Atlantic Twin Registry. MIRT consisted 94 individuals who do not have baseline, representing 43 twin pairs (41 dizygotic), one set triplets, 5 whose did participate. A broad variables assessed including psychological factors (e.g., lifetime history major (MD)); social stress perceptions experiences); , indicators metabolic BMI, blood pressure (BP), HbA1c) immune functioning pro- anti-inflammatory cytokines), as well collection RNA. re-assessed 6-month later. Intra-class correlation coefficients (ICC) descriptive comparisons used explore variation social, across time within pairs. Results Mean age was 53 years, 68% female, 77% identified white. One-third had MD, 18 sibling sets discordant MD. MD associated with higher systolic (139.1 vs 132.2 mmHg, p=0.05) diastolic BP (87.2 vs. 80.8 p=0.002) IL-6 (1.47 0.93 pg/mL, p=0.001). HbA1c, or other markers. While characteristics co-twins significantly correlated, all within-person ICCs than within-pair correlations HbA1c ICC=0.88 ICC=0.49; ICC=0.64 within-pair=0.54). Among substantially markers, but positively stress. Conclusions studies potential clarify diabetes, recently completed processing RNA samples permits future exploration gene expression mechanism.
