Study Arms (2)

Intensive Life-Style Counseling

EXPERIMENTAL

Women with pre-diabetes randomized to the ILI will attend an intensive 12-week group program of nutritional education, diet, behavior modification and structured exercise, which is based on the published curriculum from the Diabetes Prevention Program (DPP) "Lifestyle Balance" program, but modified for a group format and to be more culturally and linguistically appropriate for this population.

Behavioral: Intensive Lifestyle Intervention

Usual Care Control

NO INTERVENTION

Women with pre-diabetes randomized to usual care will be offered 30 minute appointments with a medical provider to review their diagnosis, risk for diabetes, and stress the importance of lifestyle changes to prevent diabetes, including weight loss and exercise and setting individual goals for these. Usual care participants will be encouraged to achieve goals equivalent to the ILI group: to reduce their weight by 7%, and to increase their physical activity to approximately 150 minutes moderate intensity exercise per week. They will be offered a consultation with an FHCHC nutritionist to achieve dietary/weight loss objectives. Participants are offered printed educational materials which are language and literacy-appropriate.

Interventions

Women with pre-diabetes randomized to the ILI will attend an intensive 12-week group program of nutritional education, diet, behavior modification and structured exercise, which is based on the published curriculum from the DPP "Lifestyle Balance" program, but modified for a group format and to be more culturally and linguistically appropriate for this population.

  • Subjects must have had a 2 hour 75 gram Oral Glucose Tolerance Test (OGTT) with fasting glucose between 100 and 126, or 2 hour glucose between 140 and 200 mg/dl in order to participate in this study within the 4 months prior to enrollment.

  • Subjects must have no medical contraindications to exercise or dieting.

You may not qualify if:

  • Subjects will be excluded from the study if they have diabetes or other serious medical or psychiatric condition that would preclude participation in the ILI program.
