Early-Life Nutrition, Growth Trajectories, and Long-Term Outcome

Area of Science:

• Pediatrics
• Nutritional Science
• Public Health

Background:

• Nutrition during the first 1,000 days is critical for lifelong health.
• Infants at risk for later morbidity include very-low-birth-weight (VLBW) infants, those from developing countries with low birth parameters, and children in trials for obesity prevention.

Purpose of the Study:

• To review long-term anthropometric follow-ups of high-risk infants.
• To assess the impact of nutritional interventions on growth and health outcomes.
• To identify factors influencing growth trajectories and long-term health.

Main Methods:

• Review of long-term anthropometric follow-ups of VLBW infants receiving fortified breast milk.
• Analysis of growth data from breastfed infants in developing countries with low birth weight/length.
• Examination of randomized controlled trials (RCTs) on breastfeeding and formula protein content for obesity prevention.

Main Results:

• Intrauterine growth retarded (IUGR) infants showed slower weight gain and lower weight up to 24 months when given fortified breast milk.
• In developing countries, birth anthropometrics strongly predict growth, with WHO 0 z-scores as a benchmark.
• Low-protein formulas and breastfeeding are associated with slower early growth but lower BMI and obesity risk later in childhood.

Conclusions:

• IUGR infants require specialized attention and improved fortification for adequate weight gain.
• Maternal factors and early nutrition are crucial for preventing stunting and improving birth parameters.
• Breastfeeding and appropriate protein intake in infancy are key for healthy growth trajectories and reduced long-term obesity risk.
