Automated Telephone Nutrition Support
The Use Of Automated Telephone Nutrition Support In Spanish-Speaking Latino Patients With Diabetes
The Automated Telephone Nutrition Support (ATNS) study investigates the effect of automated telephone nutrition support on diet and glycemic control among Spanish-speaking diabetics in Oakland.
The Automated Telephone Nutrition Support (ATNS) study is a joint effort between the University of California at San Francisco, La Clinica de la Raza, and patients living with diabetes in Fruitvale (Oakland). Our goal is to see if motivated people with diabetes are able to get their blood sugar under better control by choosing a healthier diet. Since it's hard to eat a healthy diet, one of the ways we are trying to help is by calling people, having them record what they've eaten, and reminding them of the right foods to eat. The innovative part is using an automated telephone system to call them to have them record their dietary choices and giving them feedback immediately regarding what to modify as appropriate.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Diabetes Mellitus
Behavioral: Automated Telephone Nutrition Support
See Intervention Group description.
Other Name: ATNS
  • No Intervention: Control Group
    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).
  • Experimental: Intervention Group
    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.
