CHIME Study Comparing Two Behavioral Health Interventions to Support Healthy Weight in Pregnant and Postpartum Women

What this Trial Is About

Researchers are evaluating how three different strategies to overcome barriers to resources and provide nutrition and physical activity counseling affect healthy weight in pregnant and postpartum women. The study focuses on which of two multi-level, multi-component interventions is more effective in reducing maternal weight retention 12 months after giving birth. The trial also compares these interventions to usual care, aiming to understand their impact on maternal postpartum weight and related health outcomes. Participants are randomly assigned to one of three groups a self-management intervention offering social needs supports like grocery and transportation help combined with self-directed behavior tools a community-based intervention involving detailed social needs assessments, active referral assistance, and group and individual physical activity support or usual care, which includes standard social needs screening and provider-based lifestyle counseling. The interventions start in early pregnancy and continue until 12 months postpartum. Throughout the study, participants complete five research visits that include questionnaires, dietary recalls, in-depth interviews, body measurements, and blood collection via finger stick or blood panels. Researchers monitor maternal postpartum weight retention as the primary outcome at 12 months postpartum, along with household social needs and perinatal health outcomes. The study includes ongoing assessments and supports to track progress and adherence over the intervention period.
