Addressing obesity in the first 1000 days in high risk infants: Systematic review

Area of Science:

• Public Health
• Pediatrics
• Nutrition Science

Background:

• Childhood obesity is a significant public health concern requiring early intervention.
• Many preventive strategies do not target high-risk infants effectively.
• Identifying and intervening in early life is crucial for long-term weight management.

Purpose of the Study:

• To systematically review interventions delivered before two years of age aimed at reducing excess weight gain in high-risk infants.
• To evaluate the effectiveness of antenatal and postnatal interventions on infant weight trajectories.

Main Methods:

• Systematic review of interventions delivered before age two targeting high-risk infants.
• Searched six databases, identifying 49 papers from 38 studies meeting inclusion criteria.
• Interventions focused primarily on infant and/or maternal nutrition, with outcomes assessed beyond 28 days.

Main Results:

• Nine interventions showed some evidence of improved child weight trajectory, though effects diminished over time.
• Effective interventions often involved longer parent engagement and health professional support.
• Two low-quality studies reported worse weight outcomes in intervention groups.

Conclusions:

• Early-life interventions show potential for ameliorating excess weight gain in high-risk infants.
• Sustained engagement and professional support are key components of successful interventions.
• Further high-quality research is needed to optimize early obesity prevention strategies.
