Study Arms (2)

Control Group

NO INTERVENTION

Patients in this (the control group) will be eligible to receive the intervention (see "Intervention Group") after 12 weeks (essentially when the trial is over).

Intervention Group

EXPERIMENTAL

Patients in the intervention group will receive automated telephone calls at regular intervals twice a week. The system will be programmed to call them at these intervals until contact. The ATNS system will solicit information from them in a culture specific manner, inquiring as to what foods they are eating each meal, each day, and each month. The ATNS system will then make proactive suggestions regarding low glycemic index foods, giving encouragement and feedback as appropriate.
