02 Jul 2019 --- Infants and young children with low levels of vitamin D may be at greater risk of high blood pressure later in childhood, according to a new study from the Boston Medical Center, US. The study, published in the American Heart Association’s (AHA) journal Hypertension, found that children born with adequate vitamin D levels, compared to children born with low levels, had about a 60 percent higher risk of elevated systolic blood pressure between ages 6 and 18. The researchers call for vitamin D testing and treatment during pregnancy in order to prevent high blood pressure later in life.
