Randomized controlled trial of an early child obesity prevention intervention: Impacts on infant tummy time.

Objective: To describe infant activity at 3 months old and to test the efficacy of a primary care-based child obesity prevention intervention on promoting infant activity in low-income Hispanic families.

Methods: This study was a randomized controlled trial (n = 533) comparing a control group of mother-infant dyads receiving standard prenatal and pediatric primary care with an intervention group receiving "Starting Early," with individual nutrition counseling and nutrition and parenting support groups coordinated with prenatal and pediatric visits. Outcomes included infant activity (tummy time, unrestrained floor time, time in movement-restricting devices).

Randomized Controlled Trial of a Primary Care-Based Child Obesity Prevention Intervention on Infant Feeding Practices.

Objective: To determine the effects of a child obesity prevention intervention, beginning in pregnancy, on infant feeding practices in low-income Hispanic families.

Study Design: The Starting Early randomized controlled trial enrolled pregnant women at a third trimester visit. Women (n = 533) were randomly allocated to a standard care control group or an intervention group participating in prenatal and postpartum individual nutrition/breastfeeding counseling and subsequent nutrition and parenting support groups coordinated with well-child visits.

Material Hardship and Internal Locus of Control Over the Prevention of Child Obesity in Low-Income Hispanic Pregnant Women.

Objective: To determine the relations between household material hardships and having a low internal locus of control over the prevention of child obesity in low-income Hispanic pregnant women.

Methods: We performed a cross-sectional analysis of baseline data collected during a third trimester prenatal visit from women participating in the Starting Early Study, a randomized controlled trial to test the efficacy of a primary care-based family-centered early child obesity prevention intervention. Using multiple logistic regression analyses, we determined whether 4 domains of material hardship (food insecurity, difficulty paying bills, housing disrepair, neighborhood stress), considered individually and also cumulatively, were associated with having a low internal locus of control over the prevention of child obesity.
