Prenatal and Pediatric Primary Care-Based Child Obesity Prevention Program: A Randomized Trial

Area of Science:

• Pediatric Health
• Public Health Interventions
• Nutritional Science

Background:

• Childhood obesity is a significant public health concern, particularly in low-income and Hispanic populations.
• Early life interventions, starting during pregnancy, show promise for preventing excessive weight gain.
• Primary care settings offer a valuable platform for delivering such interventions.

Purpose of the Study:

• To evaluate the impact of a primary care-based child obesity prevention program initiated during pregnancy.
• To assess effects on early childhood weight outcomes in low-income Hispanic families.
• To determine if the intervention influences weight-for-age z-scores, obesity prevalence, and weight gain trajectories.

Main Methods:

• A randomized controlled trial involving 566 pregnant women in their third trimester.
• Intervention group received the Starting Early Program with nutrition counseling and parenting support.
• Control group received standard care; outcomes measured from birth to age 3 years.

Main Results:

• Intervention infants showed lower mean weight-for-age z-scores at 18 months and 2 years.
• No significant group differences in obesity prevalence were observed by age 3.
• Higher program attendance correlated with decreased obesity rates at age 3.

Conclusions:

• The primary care intervention demonstrated a positive effect on weight outcomes through age 2.
• Sustaining intervention effects beyond age 2 requires further investigation.
• Program attendance is a key factor in achieving long-term obesity prevention success.
