Vitamin D and youth blood pressure

Adults with high blood pressure (BP) are often low in vitamin D, raising the question, would low vitamin D levels at birth predict BP problems later?

In this study, doctors measured vitamin D levels and systolic BP in 775 children from birth through 18 years of age. Doctors defined low vitamin D as less than  11 nanograms per milliliter of blood (ng/mL) or  27.5 nanomoles per liter (nmol/L) at birth.

Compared to kids with adequate levels, those born with low vitamin D were 60 percent more likely to have elevated BP between the ages of six and 18. Kids whose vitamin D levels remained low through early childhood were twice as likely as kids with good levels to have elevated BP from ages three to 18. The findings may prompt the American Academy of Pediatrics to recommend screening all pregnant women and young children for vitamin D levels to reduce BP later in life.
