A Pilot Study of the Effects of Diet and Behavioral Interventions on Health in Diabetics

University of California, San Francisco34 enrolled

Overview

The study is a small pilot, designed to provide data regarding the feasibility and acceptability of conducting such a study on a larger scale. The present study is a randomized controlled clinical trial comparing two mindfulness-based lifestyle modification programs to help people manage diabetes and lose weight, one using on a low-carbohydrate diet (LC) and the other using a moderate-carbohydrate diet promoted by the American Diabetes Association (ADA). Intervention content will include information about nutrition (carbohydrate restriction or American Diabetes Association recommended diet) and emotion regulation and mindful eating strategies.

Approximately 40 individuals with Type II diabetes or prediabetes will be randomized in a 1:1 ratio to treatment groups. Groups will meet for 12 weekly sessions, then approximately biweekly for 3 sessions, for a total of 15 1.5-2 hour sessions over 4.5 months. Participants will be evaluated at 0, 1 month, 3 months, and 6 months. Our outcome of interest is HbA1c (glycated hemoglobin, a measure indicative of blood glucose levels and tied to diabetes severity).

Outcomes

Primary Outcomes

Hemoglobin A1c

We test whether Hemoglobin A1c changes from pre-intervention to 3 months. The key outcome measure will compare the two diet groups, but we will also assess whether statistically significant changes occur within groups from pre-intervention to 3 months.

Time frame: Change from baseline to 3 months
