Outcome Measures

Primary Outcomes (4)

  • Diabetes. measured by HbA1c and Fasting blood glucose (FBG)

    We define type 2 diabetes (T2D) as either FBG 100-125 mg/dl or HbA1c of \>= 6.5%

    3 years

  • Lifestyle modifications by decreasing adiposity indicators

    We will evaluate this by : weight in Kg, height in mts. They also be combined to report BMI/m2, and waist circumference

    Will be evaluated every 3 months during the 36 month period

  • Caloric intake

    From food-frequency questionnaires.

    Every 3 months during the 36 month period

  • Physical Activity

    Expresses ad the average metabolic equivalents (METs)-hours/week

    Every 3 months during the 36 month period

Secondary Outcomes (4)

  • Implementation process outcomes at the clinic level. Using a questionnaire

    5 years

  • Implementation process outcomes at the clinician level. Using a questionnaire
