With awareness about sunshine exposure and vitamin D supplementation, vitamin D deficiency would have declined over the last two decades.

Cord-blood was drawn at delivery, and fasting maternal blood was drawn for serum total calcium, phosphate, alkaline phosphatase, 25(OH)D, and intact-PTH assessment. Serum 25(OH)D and PTH were measured by chemiluminescence assay.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The median (IQR) serum 25(OH)D of mothers and newborns was 11.8 (6.9-19.1) and 13.7 (7.9-24.7) ng\/mL, respectively.
