Reducing Obesity in Underserved Postpartum African American Women

Not Applicable

Completed

• Conditions: Obesity
• Interventions: Behavioral: Nutrition and physical activity education

• Registration Number: NCT02448563
• Lead Sponsor: Boston Medical Center

Brief Summary

In this proposal, the investigators will develop a culturally-tailored, 8-week clinic-based weight loss program to reduce obesity among postpartum African American (AA) adult women that can be integrated into a postpartum care model within a clinical setting.

Detailed Description

The investigators proposal adapts The Diabetes Prevention Program (DPP) 16 session core curriculum to our 8 session model and in addition uses the cultural tailoring techniques of the DPP to address the needs of our AA population in several ways: 1) The reference materials and lesson handouts include information about the types of foods and cooking methods used by an AA culture (see Other Study Documents); 2) Topics are selected for group classes that are most appropriate for our participants such as Hip Hop or Salsa dancing for physical activity.

Participants will be randomized during the early postpartum period to either usual care or intervention. Usual care participants will be offered the weight management standard of care which is one visit with a dietitian in the Nutrition and Weight Management Center. Intervention participants will be assigned a Birth Sister for the postpartum period. They will also attend 8 weekly sessions for the weight loss program. All participants will complete study assessment visits at 6 weeks postpartum and 15 weeks postpartum.

Arm && Interventions

Group	Intervention	Description
Intervention	Nutrition and physical activity education	Weekly, in-person, support groups providing nutrition and physical activity education

Primary Outcome Measures

Name	Time	Method
Feasibility as Measured by Attendance at Group Sessions and Barriers to Attendance (Logs Kept by Research Staff)	Weekly up to 8 weeks

Secondary Outcome Measures

Name	Time	Method
Change From Baseline Weight to 8 Weeks	Baseline and 8 weeks
Participant Satisfaction as Measured by Questionnaire and Exit Interview	8 weeks
Changes in Baseline Eating Behaviors to 8 Weeks as Measured by Eating Behavior Patterns Questionnaire	Baseline and 8 weeks	Items were rated on a 5 point scale (1 strongly disagree, 2 disagree, 3 neutral or not applicable, 4 agree, 5 strongly agree). We summed the scores of the component items that comprised each scale (and higher scores are those where respondents are more likely to strongly agree). What is reported in the tables are the differences in raw scores computed by subtracting the summed scores at baseline from that measured at 8 weeks (difference = 8 weeks score - Baseline score).
Changes in Baseline Body Image to 8 Weeks as Measured by the 34-item Multidimensional Body Relations Questionnaire	Baseline and 8 weeks	The Multidimensional Body Relations Questionnaire (MBSRQ-AS) includes the following subscales: Appearance Evaluation, Appearance Orientation, Overweight Preoccupation, Self-Classified Weight, and the Body Areas Satisfaction Scale (BASS). We summed the scores of the component items that comprised each scale (and higher scores are those where respondents are more likely to strongly agree). What is reported in the tables are the differences in raw scores computed by subtracting the summed scores at baseline from that measured at 8 weeks (difference = 8 weeks score - Baseline score). Scale ranges from 1-5 (1=definitely disagree, 2=mostly disagree, 3=neither agree nor disagree, 4=mostly agree, 5=definitely agree) with higher scores reflecting better outcome. A positive value shows improvement in that subscale over time.
Changes in Baseline Physical Activity to 8 Weeks as Measured by the Kaiser Physical Activity Scale	Baseline and 8 weeks	Activity indices were created for each domain of activity (household/caregiving, occupational, active living, sports/exercise) by summing the domain-specific categorical responses and dividing by the number of items, giving an average value that ranged from 1 to 5. We summed the scores of the component items that comprised each scale (and higher scores are those where respondents are more likely to strongly agree). What is reported in the tables are the differences in raw scores computed by subtracting the summed scores at Baseline from that measured at 8 weeks (difference = 8 weeks score - baseline score).
Waist Circumference at 8 Weeks	8 weeks
