Research Question(s):
The research team is recruiting 900 English- and Spanish-speaking parent-infant pairs from six primary care clinics. The team is assigning the pairs by chance to receive either Greenlight or Greenlight Plus for two years. At the start of the study and throughout the child's first two years of life, the team is interviewing families and reviewing medical records to see how each baby is growing. The team wants to know how Greenlight and Greenlight Plus compare in promoting healthy weight gain for different groups based on language, race, ethnicity, and health literacy.
