BACKGROUND: At the turn of the 20th century, women commonly died in childbirth due to rachitic pelvis. Although rickets virtually disappeared with the discovery of the hormone vitamin D, recent reports suggest vitamin D deficiency is widespread in industrialised nations. Poor muscular performance is an established symptom of vitamin D deficiency. The current U.S. cesarean birth rate is at an all-time high of 30.2%. The researchers’ analyzed the relationship between maternal serum vD status, and prevalence of primary cesarean section.
METHODS: Between 2005 and 2007, we measured maternal and infant serum vD at birth and abstracted demographic and medical data from the maternal medical record at an urban teaching hospital (Boston, MA) with 2500 births per year. We enrolled 253 women, of whom 43 (17%) had a primary cesarean.
RESULTS: There was an inverse association with having a cesarean section and serum vD levels. They found that 28% of women with serum vD less than 37.5 nmol/liter had a cesarean section, compared with only 14% of women with vD 37.5nmol/liter or greater (P = 0.012). In an analysis controlling for race, age, education level, insurance status, and alcohol use, women with vD less than 37.5 nmol/liter were almost 4 times as likely to have a cesarean than women with vD 37.5 nmol/liter or greater (adjusted odds ratio 3.84; 95% confidence interval 1.71 to 8.62).
CONCLUSION: Vitamin D deficiency was associated with increased odds of primary cesarean section.
“A compelling story and ties in nicely with what we know about MS. The increased risk of MS in people born by C-section is an association and is not causal. Vitamin D deficiency may explain them both.”
Hmmm. I don't buy it. I would wager the majority of ppl w/MS were NOT a C-section.
Another diversion to keep the fear of the unknown high up. Medieval catholic church invented this method of mass manipulation through inventing of ubiquitous little dangers.And then went to sell indulgences (DMD drugs)
I don't understand this post. Someone earlier said that there are essential bacteria in the vagina that the baby swallows when the mother is giving birth. Is this true?
Cesarean delivery also increases the risk of type I diabetes which is another autoimmune disorder. http://www.ncbi.nlm.nih.gov/pubmed/18292986
Re: "I don't understand this post. Someone earlier said that there are essential bacteria in the vagina that the baby swallows when the mother is giving birth. Is this true?"Yes, there is evidence showing that the bacteria babies get exposed to is different depending on if they are born via C-section or the normal vaginal route. Proponents of the hygiene hypothesis will claim that this is the reason why c-section increases your risk of auto-immune disease. I am not sure if this is established and I wanted to point our that this could be confounded by low vitamin D levels.
