Details and patient eligibility

About

The purpose of this study is to enroll approximately 450 subjects to see if a behavioral weight management program is successful in helping TRICARE beneficiaries who are pregnant or post-partum to manage their weight during and after their pregnancy.

Full description

Investigators will randomize 450 consented participants to 1 of 3 interventions: a) a gestational weight gain intervention (GWG-only); b) a postpartum weight loss intervention (PPWL-only), or c) a combined gestational weight gain and postpartum weight loss intervention (GWG+PPWL) to determine the efficacy of the interventions on GWG as well as PPWL.

Procedures: Interested individuals will be directed to call the study telephone number to learn more and determine whether eligibility criteria is met. Individuals who meet the telephone screening eligibility criteria will be invited to schedule a Screening Visit, during which written informed consent will be obtained. At this visit, eligibility will be assessed and measures will be administrated. The potential participant will also be asked to complete a one-week dietary and exercise self-monitoring run-in and receive medical clearance from their obstetrician to participate. Should she continue to be interested, she will return for a Baseline Visit and will be randomized.

Randomized participants will have 5 in person scheduled visits after their Screening Visit and Baseline Visit to the Wilford Hall Ambulatory Surgical Center (WHASC) or San Antonio Military Medical Center (SAMMC) Obstetrics (OB) clinic. These visits will be scheduled at gestational week 32, 36, as well as at 6- weeks, 6-months, and 12- month postpartum. At these visits, physical measurements will be collected and participants will complete various questionnaires.

430 participants in 3 patient groups

Gestational weight gain intervention (GWG-only)
Experimental group
Description:
The GWG intervention will begin upon randomization to the GWG-only or the GWG+PPWL arm, and continue until the birth of the participant's child.
Treatment:
Behavioral: Gestational weight gain intervention
Postpartum weight loss intervention (PPWL-only)
Experimental group
Description:
The PPWL intervention will begin at 6-weeks postpartum (when most women will be approved for weight loss and exercise by their obstetrician) for those participants randomized to the PPWL only or the GWG+PPWL arms, and will continue until 6-months postpartum.
Treatment:
Behavioral: Postpartum weight loss intervention
Combined
Experimental group
Description:
During the gestational phase participants will receive the same intervention as the GWG only group. During the postpartum phase participants will receive the the same intervention as the PPWL group.
Treatment:
Behavioral: Postpartum weight loss intervention
Behavioral: Gestational weight gain intervention
