Abstract

Exclusively breastfed preterm babies are dependent almost entirely on the available
vitamin D content of breast milk for their metabolic and physiologic needs. The
breast milk content of vitamin D correlates with the serum levels of vitamin D in the
mother. This study investigates the trend in plasma vitamin D levels of preterm neonates
who are exclusively breastfed between birth and 10 weeks of life. The proportion
of mothers with low plasma vitamin D levels at birth was 41.7%, while it was 50%
in the preterm babies. The plasma vitamin D levels in infants showed a strong positive
correlation with maternal plasma levels at birth. By the 10th week postnatal age, the
proportion of mothers with low plasma vitamin D had reduced slightly to 39.6%, but
the proportion of babies with low plasma vitamin D had increased significantly to
81.3% while being fed exclusively on breast milk. It is, therefore, recommended that
pregnant women should have vitamin D supplementation and that babies delivered
preterm should have vitamin D supplementation.
