This study will evaluate the effects of screening for type 2 diabetes mellitus (T2DM) and brief counseling about screening test results on weight and key health behaviors among Veterans with risk factors for T2DM. Study participants will be randomly assigned to one of two study groups: (1) Blood Test Group or (2) Brochure Group. Participants in the Blood Test Group will complete a blood test called hemoglobin A1c (HbA1c) which measures average blood sugar levels. Participants will receive brief counseling about the results from their primary care provider or someone authorized to speak on their behalf. Participants randomly selected for the Brochure Group will review a handout from the VA National Center for Health Promotion and Disease Prevention (NCP) on recommended screening tests and immunizations. All participants will be asked to complete a survey prior to study group assignment, immediately after a Primary Care appointment, 3 months after enrollment, and 12 months after enrollment.
