Outcome Test Measurement
Primary Outcome Measures HbA1c/Fasting Lipid Profile Blood specimens will be obtained at baseline, 3-, 6- and 12-months visits.
Secondary Outcome Measures Laboratory Measurements Blood specimens will be obtained at baseline and 12-months visits.
  Physical Activity The seven-day physical activity recall (PAR) will be used to measure of physical activity [29, 30].
  Diet Dietary intake will be assessed using the Block 1998 Food Frequency Questionnaire [3136].
  Medication Adherence The eCAP® electronic compliance monitor (Information Mediary Corporation, Ottawa, Canada) will serve as the primary measure of medication adherence for this study.
  Self-monitoring of Blood Glucose Glucometer downloads will be used to assess self-monitoring adherence.
  Blood pressure measurements Blood pressure readings will be obtained at baseline, 3-, 6- and 12-months by a trained RA using automated BP monitors (OMRON IntelliSense™ HEM-907XL) with the patient seated comfortably for 5 minutes prior to the measurements.
  Resource Utilization & Cost The perspective of cost will be that of the payer. Previously validated questions on resource utilization will be administered as part of the baseline, 3-, 6-, and 12-month assessments.
