Decreasing Stress in Diabetes

Purpose

The purpose of this study is to conduct a randomized controlled trial (RCT) to determine the effects of an online 6-month Mindfulness-based stress reduction (MBSR) intervention compared to an active control Stress Management Education (SME) on glucose control in adults with uncontrolled type 1 or type 2 diabetes. The study will randomize at least 290 adults with uncontrolled diabetes to a 6-month MBSR intervention or SME control. Both MBSR and SME will be delivered online by experienced instructors in a live interactive virtual classroom using videoconferencing. Outcomes will be assessed at baseline, a follow-up phone call after Class #4, and study visits at 2-months and 6-months.

Intervention Model Description
This is a randomized, parallel group two-arm trial that will determine the effects of an online 6-month Mindfulness-based stress reduction (MBSR) intervention compared to Stress Management Education (SME) (active control) on glucose control in at least 290 patients with uncontrolled diabetes. Both MBSR and SME will be delivered online by experienced instructors in a live interactive virtual classroom using videoconferencing.

Masking
Double (Investigator, Outcomes Assessor)
Masking Description
The PI, study coordinator, and all study personnel collecting outcomes, will be blinded from the treatment assignments. Only the MBSR and SME instructors and the study personnel who schedule the classes, videorecord the classes, and code the videos will have knowledge of the assignments, and these individuals will not be involved in the collection of outcomes. Subjects will be asked to keep their treatment assignment concealed from study personnel collecting outcomes. However, complete blinding may not be possible given the nature of this study.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Mindfulness Based Stress Reduction
  • Behavioral: Mindfulness Based Stress Reduction
    Subjects randomized to Mindfulness-Based Stress Reduction (MBSR) will receive the 8-week University of Massachusetts Authorized MBSR curriculum followed by monthly mindfulness boosters in Months 3 to 6. The University of Massachusetts MBSR curriculum was selected for the intervention, as it is the most standardized and researched mindfulness program that has been shown to reduce psychological distress in various patient populations.
Active Comparator
Stress Management Education
  • Behavioral: Stress Management Education
    Subjects randomized to Stress Management Education (SME) will receive health education on nutrition (adapted for the type 2 diabetes population), exercise as gentle stretching to match yoga in MBSR, and other general health topics that may be relevant to the type 2 diabetes population such as sleep, time management, etc. Stress Management Education does not have any mindfulness in it. Stress Management Education was specifically created as a control condition for MBSR studies so it matches MBSR for time, social support, homework, etc.

Detailed Description

Specific Aims are: 1) To conduct a randomized controlled trial to determine the effects of an online 6-month Mindfulness-Based Stress Reduction (MBSR) intervention compared to an active control Stress Management Education (SME) on glucose levels in at least 290 adults with uncontrolled type 1 or type 2 diabetes. Both MBSR and SME will be delivered online by experienced instructors in a live interactive virtual classroom using videoconferencing. The primary outcome will be hemoglobin A1c (HbA1c), a measure of the average glucose level over the past 3 months. We hypothesize that between the two groups, there will be a clinically significant 0.5% absolute difference in the mean change in HbA1c from baseline to 6-months. We will also look at the 2-month HbA1c, however it may be too brief a time period to fully capture the impact of MBSR. An absolute reduction in HbA1c of 0.5% would be expected to reduce the risk of any diabetes-related complication by at least 10%. Additionally, we will assess fasting glucose as a secondary outcome as it is linked with adverse health outcomes, and can be lowered with MBSR based on our pilot study; 2) To determine the effects of online MBSR compared to SME control on psychosocial, behavioral and physiological mechanisms potentially mediating the effects of MBSR and/or SME on glucose levels in adults with uncontrolled diabetes. Secondary outcomes include: diabetes-related distress, subjective stress, craving, the impact of COVID-19 on subjects' lives, subject expectancy, dietary intake, physical activity, and serum hsCRP as a marker of chronic inflammation. Adverse Childhood Experiences (ACEs) will be assessed at baseline. It is hypothesized that these measures may mediate the effects of MBSR and/or SME on glucose. The proposed study has the potential to transform current standards of care for diabetes by using a novel long-term MBSR intervention as a powerful adjunct intervention for diabetes. MBSR could impact the clinical picture of diabetes by empowering patients with skills for strengthening their own internal resources to promote self regulation and adaptive coping and reduce stress reactivity, which are all essential for implementing healthy behaviors and are expected to lead to improved glucose control and reduced risk of diabetes complications. This proposal is relevant to the mission of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to conduct research on diabetes to improve people's health and quality of life.
