ClinConnect Summary

The CHIME trial is studying different ways to help pregnant women and new mothers maintain a healthy weight during and after pregnancy. The main goal is to see which of two specific programs—both designed to offer support and guidance on nutrition and physical activity—works best in helping women reduce weight gained after childbirth. The trial will include women who are 18 years or older, currently pregnant with a single baby, and who identify as Black or Hispanic, or are on Medicaid.

Participants will be involved from early pregnancy until 12 months after giving birth and will attend five visits where they will answer questions, share details about their diet, and undergo some health measurements. This study aims to provide valuable insights into effective support for mothers, especially those facing barriers to healthy living. If you're interested and meet the eligibility criteria, you could play a crucial role in helping improve maternal health.
