Maternal 25-Hydroxyvitamin D and Parathyroid Hormone Concentrations and Offspring Birth Size

Abstract

Low maternal 25-(OH)D in late pregnancy is associated with reduced intrauterine long bone growth and slightly shorter gestation. The long-term consequences for linear growth and health require follow-up. The positive relationship between maternal PTH and measures of infant size may relate to increased mineral demands by larger babies, but warrants further investigation.
