Vitamin D Council podcast 10: Carole Baggerly of GrassrootsHealth
Episode notes by Dr. Cannell of Vitamin D Council
Baggerly is the head of GrassrootsHealth, a fellow non-profit organization focusing on migrating vitamin D research into practice. Though faced with many challenges along the way, Baggerly and team found that pregnant women, their physicians and the institutions were ready to begin implementing vitamin D education, testing and supplementation into their prenatal regimen.
In this episode, Baggerly discusses the success of her vitamin D program for pregnant women in South Carolina and provides insight on a study in which she played an instrumental role in publishing regarding vitamin D status and premature birth risk.
Notes by Henry Lahore of Vitamin D Life
2012 study looked only at treatment groups
Baggerly re-analyzed to look at the vitamin D level actually achieved
Preterm birth rate reduced 57 percent by Vitamin D – Nov 2015 had the following
Most of the white women already had 30 ng of vitamin D, so not as much reduction in pre-term bith
Study at 40 ng was confirmed 2 ways – the data and March of Dimes
Liza Bodnar also found same thing – 3,000 women Feb 2015
Starting year of organizations: Viamin D Council 2001,. Grassroots 2007, Vitamin D Life 2009
She is training the full OBGYN staff – not just the OBGYN doctors
She has two continuing medical education courses online
She had started 500 women – but they expanded it to 2,000 women per year
Compliance: Phone encouragement does not seem to help, have online chat room
They do have texting to the women – 100% of them have cellphones
Vitamin D is now the standard of care at that institution – so physician is not at risk for law suits
Funding for South Carolina was by Managed Care Insurance
Cost of the 2 year project is $450,000 (for 500 women?)
Estimated cost benefit $8 million annually for 2000 women
Dr. Cannell would like to have children continue to be on vitamin D – but nothing is funded, or implemented
Dr. Cannell believes Vitamin D is needed by toddler, wherease 98% of researchers believe that Autisim is lack of D during pregnancy
Expansion of providing vitamin D during pregnancy outside of South Carolina
Generally the hospitals that are wanting to do it
- Missoula Montana – in process ,
- initial in Connecticut and Arkansas
Dr. Cannell: Probably should have only 1 claim – premature birth, will be easier for people to understand than 10 claims
She wants to tell journals that It is essential that Vitamin D analysis be done on outcome serum levels, not dosing levels
e.g. 40 ng, not 4,000 IU dosing
