mothers and caregivers investing in children study 2.0

Conditions: Childhood Obesity Prevention; Parenting Behavior; Infant Growth

Summary: the study will use a longitudinal, randomized control trial design to determine intervention impact on parent and child behaviors, and infant health. the two intervention groups include: 1) magic-feed+; and 2) magic-safe. this trial is an efficacy trial of the magic-feed and magic-safe program that has been successfully implemented with families as part of the magic 1.0 program trial (irb#: 2015040017). * the primary aim is to investigate each intervention's impact on infant bmiz at 13 months. * the investigators will also assess the effect of magic-feed on caregiver nutrition knowledge and feeding practices, responsive feeding, infant diet, and child self-regulatory abilities and assess how these factors impact child self-regulation of eating and adiposity. * finally, the investigators will determine if the interventions demonstrate the factors necessary to be a successful intervention as determined by the re-aim and prism frameworks.

obesity is a significant public health problem and risk begins early in life. in the us, over 19% of children ages 2-19 have obesity with 6% of these children classified with severe obesity. obesity prevalence is lower among 2- to 5-year-old children (13.4%); however, by age 6, one in 5 children has obesity. rapid weight gain over the first year of life is associated with overweight or obesity in toddlers and young children, which then tracks across the life course. it is critical to intervene on modifiable factors early in life to support healthy growth and prevent obesity. this trial is implemented across the first year in this population to support child diet quality, self-regulatory skills related to eating and growth to prevent obesity. interventions during the first year of life have been implemented to prevent child obesity. most focus on breast and bottle feeding during the first 6 months or feeding across infancy. few have demonstrated lasting effects beyond infancy on a relative body size measure that accounts for height such as bmiz, and none have reported effects on long-term adiposity measured with a sensitive assessment tool or have successfully impacted long-term relative body size or adiposity. further, prior rcts have predominately been conducted via home visits. magic 2.0 uses a virtual platform which will allows us to leverage the well-established effectiveness of home visiting to be accessible to caregivers with young children.
