Summary

The First 1000 Days (conception to age 2) is a crucial period for the development and prevention of obesity and its adverse consequences in mother-child pairs and their families. The overall aim of the First 1000 Days program is to work across early-life systems to prevent obesity, promote healthy routines and behaviors, address social determinants of health, and reduce health disparities among vulnerable children and families at community health centers in the Boston, MA area. The study aims to simultaneously implement and evaluate an obesity prevention program across early life systems to reduce the prevalence of obesity risk factors within racial/ethnic minority families, close the gap in maternal-child health disparities, and assess and address social determinants of health.
