This randomized controlled trial investigated the effects of combined supplementation of vitamins A and K2 on the growth and skeletal development of 86 preterm infants. The intervention group, receiving additional vitamins A and K2, showed significant improvements in bone mineral density and height standard deviation score after 12 months compared to the control group.
Key findings
- The intervention group had higher lumbar spine and femur BMD after 12 months.
- Greater height standard deviation score (HtSDS) was observed in the intervention group.
- Serum levels of vitamins A, D, K1, K2, and 25-OH-D were significantly higher in the intervention group.
- No significant difference in adverse reactions was noted between the two groups.
Why it matters
The findings suggest that additional supplementation of vitamins A and K2 can enhance skeletal development and micronutrient status in preterm infants, which is crucial for their growth and long-term health outcomes.
