Overview
Brief Summary
The purpose of this study is to conduct a randomized controlled trial among 468 Non-Hispanic black mothers and their families to test the efficacy of MOTHERS AND OTHERS, a multi-component home visitation program, compared to an attention control (child safety) in promoting appropriate weight gain during infancy.
Detailed Description
Mothers and Others: Family-based Obesity Prevention for Infants and Toddlers will be one of the first to meet the unique needs of individual families by delivering anticipatory guidance on infant care, feeding and growth through multiple channels and to multiple caregivers. Primary modes of delivery for the Obesity Prevention Group (experimental arm) will include face-to-face counseling through 8 home visits (1 by a certified Lactation Consultant), 5 health newsletters, and approximately 160 cue-based text messages. The Injury Prevention Group (active comparator) will receive messages on child safety delivered through similar channels. Our main outcome is infant/toddler growth, captured by mean weight-for-length z-scores (WLZ) at 15 months, mean change in WLZ between 0-15 months, and likelihood of overweight (WLZ ≥ 95th percentile) at 15 months. Differences between groups are expected to be achieved through uptake of targeted health behaviors, including a greater likelihood of breastfeeding initiation, exclusivity and duration; after 6 months, higher dietary intakes of whole fruits and vegetables and lower intakes of energy-dense snack foods; age-appropriate durations of infant and toddler sleep; and, lower levels of television and electronic media exposure. We further hypothesize that these targeted health behaviors will be achieved through modifiable risk factors underpinning the intervention, namely more positive breastfeeding attitudes; higher levels of parenting and breastfeeding self-efficacy; higher levels of perceived social support; higher responsive feeding style scores; improved accuracy in perceiving infant/toddler weight status; and, diminished parental perceptions of infant fussiness.
