"In our study, more than 80 percent of African-American women and nearly half of white women tested at delivery had levels of vitamin D that were too low, even though more than 90 percent of them used prenatal vitamins during pregnancy," said Lisa Bodnar, Ph.D., M.P.H., R.D., assistant professor of epidemiology at the University of Pittsburgh Graduate School of Public Health (GSPH) and lead author of the study. "The numbers also were striking for their newborns ?92.4 percent of African-American babies and 66.1 percent of white infants were found to have insufficient vitamin D at birth."
A vitamin closely associated with bone health, vitamin D deficiency early in life is associated with rickets ?a disorder characterized by soft bones and thought to have been eradicated in the United States more than 50 years ago ?as well as increased risk for type 1 diabetes, asthma and schizophrenia.
"A newborn's vitamin D stores are completely reliant on vitamin D from the mother," observed Dr. Bodnar, who also is an assistant investigator at the university-affiliated Magee-Womens Research Institute (MWRI). "Not surprisingly, poor maternal vitamin D status during pregnancy is a major risk factor for infant rickets, which again is becoming a major health problem."
For their study, Dr. Bodnar and her colleagues evaluated data that was collected on 200 black women and 200 white women who were randomly selected from more than 2,200 women enrolled in the MWRI's Pregnancy Exposures and Preeclampsia Pre
