Diabetes Medical Nutrition Therapy in Southeastern African American Women
August 23, 2022 updated by: Stephania T. Miller-Hughes, Meharry Medical College
A two-arm randomized controlled trial design will be used.
Participants will include 291 African American women with type 2 diabetes that are at risk for development and/or progression of diabetes complications.
Both arms, diabetes medical nutrition therapy (MNT) and diabetes MNT plus motivational interviewing (MI), will include: 1) a 3-month active intervention period of six biweekly (every other week), group-based, trained nutritionist-facilitated sessions; 2) a 3-month maintenance intervention period, which will include one group-based maintenance support session; and 3) a 6-month inactive period (no contact).
The differences between arms is the integration of culturally-adapted MI exercises during the diabetes MNT plus MI active and maintenance intervention periods.
