    Abstract:
    Background/Objectives: Very low birth weight (VLBW) infants may require enhanced nutrition, even during complementary feeding. However, there are limited data on macronutrient intake during this period, particularly concerning the individual timing of the introduction of solid foods in a representative VLBW infant population. Methods: This prospective observational study analyzed macronutrient intake in VLBW infants with a gestational age < 32 weeks based on whether solid foods were introduced early (<17 weeks corrected age (CA)) or late (≥17 weeks corrected age) Nutritional intake was analyzed using a 24 h recall at 6 weeks CA and 3-day dietary records at 12 weeks, 6, 9, and 12 months CA. Results: In total, 115 infants were assigned to the early and 82 to the late group. The timing of solid food introduction did not affect macronutrient intake, except for a lower fat and higher carbohydrate intake (% of energy) in the early group at 12 weeks and 6 months CA: early vs. late, fat-12 weeks: 47.0% vs. 49.0%, 6 months: 39.2% vs. 43.3%; carbohydrates-12 weeks: 44.9% vs. 43.2%, 6 months: 51.3% vs. 48.0%. Apart from docosahexaenoic acid (DHA) and arachidonic acid (AA), dietary intake recommendations were met in both groups. While nutrient intakes varied significantly between breastfed and formula-fed infants, those with comorbidities exhibited similar nutrient intake levels compared to those without. Conclusions: Our findings suggest adequate macronutrient intakes in VLBW infants irrespective of the timing of solid introduction. However, there is a notable need to enhance dietary intakes of DHA and AA. Future research is crucial to assess whether current nutrient intakes are sufficient for VLBW infants with comorbidities.
