Lack Of Vitamin D Linked To Cesarean Section Rates
Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) found that pregnant women who are vitamin D deficient are also at an increased risk for delivering a baby by caesarean section as compared to pregnant women who are not vitamin D deficient. These findings currently appear on-line in the Journal of Clinical Endocrinology & Metabolism.
At the turn of the 20th century, women commonly died in childbirth due to "rachitic pelvis" rickets of the pelvis. While rickets virtually disappeared with the discovery of vitamin D, recent reports suggest that vitamin D deficiency is widespread in industrialized nations.
"In our analysis, pregnant women who were vitamin D deficient at the time of delivery had almost four times the odds of caesarean birth than women who were not deficient," said senior author Michael Holick, MD, PhD, director of the General Clinical Research Center and professor of medicine, physiology and biophysics at BUSM and Anne Merewood assistant professor of pediatrics at BUSM and lead author of the study.
According to Holick, one explanation for the findings is that vitamin D deficiency has been associated with proximal muscle weakness as well as suboptimal muscle performance and strength.
This study was funded by the US Department of Health and Human Services, Bureau of Maternal Child Health: R40MC03620-02-00, and by the US Department of Agriculture Cooperative State Research, Education, and Extension Service, Award.
