About this study
Official title: Family Diabetes Study (Family PALS (PArtners in Lifestyle Support)
NOTE: This study is in the trial-phase of a 5-year study that included a formative research phase (Phase 1 - IRB study # 07-1765 "Family-based Diabetes Self-management Training for African American Adults"). During the first phase, eight focus groups were conducted with 68 participants and a validation study with 215 African American patients with type 2 diabetes. The data gathered in Phase 1 informs the refinement of the intervention in this phase.
Purpose: The overall goal of this research is to evaluate, in a randomized controlled trial, a family-based diabetes self-management intervention for overweight/obese African American adults with type 2 diabetes (the "index participants") and a paired overweight family member (co-participant) who does not have diabetes. The primary outcome is weight change in the index participant.
Read the detailed description
Type 2 diabetes disproportionately burdens African Americans, and already excessive rates of diabetes are expected to increase even further as rates of obesity rise. While there is evidence that diabetes self-management training is effective in improving metabolic control, and modest weight loss can delay the onset of diabetes, the investigators have limited knowledge of the best approach to self-management training from a family perspective in high risk groups such as African Americans. Family remains a valued dimension of African American life and may be an important behavioral context for interventions to improve disease management and health outcomes. Nonetheless, there are no trials of family-based interventions to improve diabetes self-care and achieve weight loss that have involved adult families.
Participants: A total of 80 pairs (index participant + family member) or 160 adults will participate in this trial where a 20-session behavioral weight loss intervention will be tested. Participants include overweight or obese African Americans with type 2 diabetes and a paired co-participant identified as an overweight or obese adult family member without type 2 diabetes. Family members may self-describe as non-African Americans.
Procedures (methods): Study participants will be enrolled in a randomized controlled trial using a 2:1 random allocation to the special intervention (a 20-session family-based behavioral weight loss intervention) or a usual care group (controls). Following the trial, participants in the usual care group will receive a 6-session weight management intervention (over a 2-month period) based on the 20-session special intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Adult diabetes family-based weight loss interventionBehavioural
Also called intense weight loss intervention, family-based lifestyle intervention
Participants assigned to the experimental group will begin the 2o-week weight loss intervention, while delayed intervention controls will wait until the end of this period to begin their program. The weight loss intervention includes 20 weekly group-based sessions facilitated by a registered dietitian. Each group session will last about 120 minutes and include: weight check, group sharing and problem-solving, discussion of a weight control topics (nutrition, physical activity, or behavior change), physical activity and/or taste-testing. Ten sessions will include a brief component, focused on improving family relationships for better diabetes self-care. The study weight loss goal is ≥10 pounds (minimum rate-0.5 lb/week; maximum-2 lbs/week). While the control group waits, they will receive 1 newsletter with study updates and general health or diabetes information. The delayed intervention includes 6 sessions (4 weekly + 2 bi-weekly) following the same format as the experimental group.
| Study group | Role | What they receive |
|---|---|---|
| Family-based intervention | Experimental | Special intervention (20 weekly group-based sessions) to be compared with a delayed intervention control group. Receives: Behavioral: Adult diabetes family-based weight loss intervention |
| Delayed intervention controls | Other | The delayed intervention controls will continue with usual care (if patients with diabetes)and at the end of the experimental period (6 months), they will receive a 6-session weight loss intervention delivered over a 2 month period. Receives: Behavioral: Adult diabetes family-based weight loss intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in body weight
Change in weight from start to end of the 20-weekly group-based intervention. NOTE: Weekly sessions are not held during weeks where holidays occur on a scheduled session date (such that the duration of the intervention may be more than 20 weeks).
Measured: 6 months
Secondary outcomes (4)
Effect on Hemoglobin A1c
A1c change from enrollment to post-intervention.
Measured: 6 months (post-intervention)
Lifestyle behaviors
Diet and physical activity behavior changes (from enrollment or baseline to post-intervention)
Measured: 6 months
Blood pressure change
Change in systolic and diastolic blood pressure from baseline (enrollment) to post-intervention
Measured: 6 months
Change in psychosocial factors
Changes in measures of family functioning, social support and social relationships, self-efficacy, perceived barriers to diabetes self-care, and quality of life; comparing baseline to post-intervention.
Measured: 6 months
