An analysis that included 8.7 million participants finds that the rate of elevated systolic blood pressure (SBP) increased substantially globally between 1990 and 2015, and that in 2015 an estimated 3.5 billion adults had systolic blood pressure of at least 110 to 115 mm Hg, and 874 million adults had SBP of 140 mm Hg or higher, according to a study.
