Clinical Trial Summary
The purpose of this study it to determine if a culturally appropriate, church based
intervention for African Americans with type 2 diabetes, will lead to improved glycemic
(blood sugar) control.
Description:
African Americans suffer disproportionately from diabetes and its complications. To reduce
this burden of suffering, innovative interventions are needed to improve self-care behaviors
including: dietary intake, physical activity (PA), self-monitoring, and medication adherence.
The goal of this study (A New DAWN) was to develop and test a culturally appropriate,
church-based intervention to improve diabetes self-management and glycemic control.
Twenty-four African American churches in central NC were recruited and randomized to receive
the special intervention (SI-13 churches, 117 participants) or the delayed intervention
(DI-11 churches, 84 participants). The SI included an 8-month intensive phase consisting of:
1 individual dietary assessment and counseling visit; 12 group sessions; monthly phone
contact with a peer counselor (church diabetes advisor (CDA)); and 3 printed encouragement
messages from the primary care clinician. This was followed by a 4-month reinforcement phase
including monthly phone contacts from the CDA. At 8- and 12-month follow-up, HbA1c was
assessed by high-performance liquid chromatography.
At baseline, 64% of participants were female and means were: age 59, years with diabetes 9,
HbA1c 7.8%, Systolic Blood Pressure 139, Diastolic Blood Pressure 76, and BMI 35.0. A total
of 174 (87%) participants returned for 8-month measures. Adjusting for baseline values and
randomization by church, the mean HbA1c level was 7.4% for the SI and 7.8% for the DI
(difference 0.4%, 95% Confidence Interval (CI) 0.1-0.6, p = 0.009). There were no
statistically significant differences between groups for BP or BMI. Of 82 (70%) SI
participants completing an 8-month follow-up questionnaire, 65 (79%) were very satisfied with
the nutritional component, 63 (77%) were very satisfied with the PA component, and 72 (88%)
considered the program to be very helpful overall.
In A New DAWN, the SI was acceptable and produced a modest, but clinically significant,
reduction in HbA1c. These findings support the acceptability and effectiveness of
self-management interventions given in a church setting for African Americans with type 2
diabetes.
