Background/Aim: Two retrospective studies of prospective cohorts showed doubled odds of birth asphyxia among women with low plasma vitamin D levels and one reported a 4-fold increase in the odds of stillbirth. It was not known if this was caused by low sun exposure or by vitamin D per se.

Patients and Methods: The stillbirth rate, including all pregnancies in Finland and Sweden between 1994 to 2021 (n>4 million), was analysed. Due to 50% of the population having low plasma vitamin D, Finland implemented an extensive National Vitamin D fortification program in 2003, which was doubled in 2009 due to an insufficient effect. After 2009, only 10% had low vitamin D levels. Stillbirth rates were compared using cross-tabulation with 95% confidence intervals.

Results: Stillbirth rate decreased from 4.1% before 2003 to 3.2% to 2.% after 2009. Meanwhile, the Swedish stillbirth rate remained constant at 3.9% untill 2018 when the Finish fortification was implemented in Sweden. Thereafter, it decreased to 3.2%. All results had p<0.001.

Conclusion: In our large study of National vitamin D fortification, improved vitamin D status was associated with a lower stillbirth rate in a dose-dependent manner.
