Reduction in preterm births during the COVID-19 lockdown in Ireland: a natural experiment allowing analysis of data from the prior two decades - June 5
Download the preprint from Vitamin D Life
"VLBW rate per 1000 live births for January to April, 2001-2019 was 8.18 (95% CI: 7.21, 9.29).
During January to April 2020, an unusually low VLBW rate of just 2.17 per 1000 live births was observed.
The rate ratio of 3.77 (95% CI: 1.21, 11.75), p = 0.022"
From Michael Cawley, Ireland Personalized Vitamin D3 For MS with Michael Cawley Facebook group
"According to the owner of Sona nutritional supplier in Ireland,
he sold a typical 6 months of D3 supplements every 7 days since March 2020.
The Government have not recommended Vitamin D3 supplementation (even in hospitals and care homes)
but everyone is ignoring their advice and taking it anyway."
Suspect that other places around the world will also find
COVID-19 ==> want to improve immune system
==>take more vitamin D ==> improved pregnancies, asthma, etc..
Approximately 25X increased sales of Vitamin D in a 3 month time period
Imagine how much better the pregnancies would have been if the women had been taking the VItamin D for 8, 9, or 10 months
