CHIME: Comparing Health Interventions for Maternal Equity

Description

The goal of this comparative effectiveness trial is to compare how three different approaches to overcome barriers to resources and provide nutrition and physical activity counseling improve maternal healthy weight in pregnancy and postpartum.

The main question it aims to answer is which of the two multi-level, multi-component interventions has greater effectiveness in reducing maternal postpartum weight retention at 12-months postpartum.

Hypothesis (primary): Both multi-level, multi-component interventions will have greater effectiveness reducing maternal postpartum weight retention at 12-months postpartum than the usual care group.

Hypothesis (secondary): The community-based intervention will have greater effectiveness than the self-management intervention.

Participants will be asked to participate in one of the study interventions from early pregnancy until 12 months postpartum and complete five research visits. General procedures include completion of:

* Questionnaires
* Dietary recalls
* In-depth interviews
* Anthropometric measurements
* Collection of blood via finger stick or blood panel
