This study will examine the impact of providing genetic CHD and T2D risk information, with or without a supportive behavioral intervention, on promoting risk-reducing behaviors and improving clinical outcomes. In short, using a 4-group (2X2) randomized controlled trial (RCT) design, this study will determine whether incorporating multiple-marker genetic testing into risk counseling for CHD and T2D, coupled with a health coaching intervention will lead to greater changes in physical fitness, health behaviors, risk status and clinical outcomes in active-duty Air Force (ADAF), beneficiaries or dependents and AF retiree patients (N=400).
