| Summary: | Background Raised blood pressure is an important risk factor for cardiovascular diseases and chronic kidney disease.
We estimated worldwide trends in mean systolic and mean diastolic blood pressure, and the prevalence of, and
number of people with, raised blood pressure, defi ned as systolic blood pressure of 140 mm Hg or higher or diastolic
blood pressure of 90 mm Hg or higher.
Methods For this analysis, we pooled national, subnational, or community population-based studies that had
measured blood pressure in adults aged 18 years and older. We used a Bayesian hierarchical model to estimate trends
from 1975 to 2015 in mean systolic and mean diastolic blood pressure, and the prevalence of raised blood pressure for
200 countries. We calculated the contributions of changes in prevalence versus population growth and ageing to the
increase in the number of adults with raised blood pressure.
