Community-based Obesity Treatment in African American Women After Childbirth

Community-based Obesity Treatment in African American Women After Childbirth: a Randomized Controlled Trial of Women Infant Children (WIC) Mothers

The purpose of this study is to determine the effect of the community-based obesity treatment (PP), compared to usual care (UC), on changes in maternal weight over 12 months.

Descrição detalhada

The investigators propose to randomize overweight or obese, African American postpartum WIC participants (n=300) to either usual care (UC) or a community-based obesity treatment (PP) arm. Recruitment will occur in 6 of Philadelphia Women Infants Children's (WIC) clinic sites in the early postpartum period (≤ 6 months after birth). Once enrolled, participants will complete surveys and baseline assessments of their weight, waist circumference, blood pressure, and height at The Center for Obesity Research and Education (CORE). Participants will also have a fasting blood sample taken. Study staff will administer a number of questionnaires assessing demographics, psychosocial factors, contextual factors, and behavioral targets via questionnaires prior to randomization. Participants will then be randomized to the 12-month postpartum weight loss intervention (PP) or usual care (UC). Additional assessments will be conducted at 6 and 12 months post baseline. The PP arm includes expanded obesogenic behavior change goals, tailored skills training materials, interactive self-monitoring text messages, video testimonials, and interpersonal counseling support through health coach calls and Facebook. Data will be analyzed using an intent-to-treat (ITT) approach where subjects are analyzed according to their treatment assignment at randomization, regardless of level of engagement. The primary outcome is weight loss at 12 months. If successful, the expected results could provide a sustainable, low-cost, postpartum weight loss intervention model for widespread dissemination to reduce disparities in obesity and cardiometabolic comorbidities.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Sem intervenção: Usual care (UC)
Usual postpartum WIC care
Experimental: Community-based obesity treatment (PP)
The PP arm includes expanded obesogenic behavior change goals, tailored skills training materials, interactive self-monitoring text messages, video testimonials, and interpersonal counseling support through health coach calls and Facebook.
Participants in the treatment (PP) arm will receive a 5-component intervention: 1)Behavior change goals; 2)Self-monitoring; 3)Tailored skills training; 4)Video testimonials & 5)Interpersonal counseling. Both treatment and usual care arms will receive the current standard of care offered to postpartum mothers at WIC.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Weight loss (kilograms)
Prazo: At baseline and 12 months
Weight will be measured using a calibrated scale at baseline and 12-month follow-up. Weight loss will be calculated as the difference between mean 12-month and baseline weight in kilograms.
At baseline and 12 months

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Obesogenic dietary behaviors
Prazo: At baseline and 12 months
Using National Cancer Institute's Diet History Questionnaire, the investigators will assess categories of sugary drink intake, fast/fried food intake, and snacking at baseline and 12-month follow-up.
At baseline and 12 months
Insulin Resistance
Prazo: At baseline and 12 months
Blood will be drawn to assess insulin resistance (insulin and glucose). The Homeostatic model assessment for Insulin Resistance (HOMA-IR) calculation will be used to quantify participant mean insulin resistance at baseline and 12-month follow-up.
