Abstract
Background: Change in the prevalence of raised blood pressure could be due to bothshifts in the entire distribution of blood pressure (representing the combined effects ofpublic health interventions and secular trends) and changes in its high-blood-pressuretail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomenato the worldwide trends in the prevalence of raised blood pressure.Methods: We pooled 1018 population-based studies with blood pressure measurementson 88.6 million participants from 1985 to 2016. We first calculated mean systolic bloodpressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised bloodpressure by sex and 10-year age group from 20–29 years to 70–79 years in each study,taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specificmean blood pressure. We calculated the contributions of change in mean SBP andDBP, and of change in the prevalence-mean association, to the change in prevalence ofraised blood pressure.Results: In 2005–16, at the same level of population mean SBP and DBP, men andwomen in South Asia and in Central Asia, the Middle East and North Africa would havethe highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In mostregion-sex-age groups where the prevalence of raised blood pressure declined, one halfor more of the decline was due to the decline in mean blood pressure. Where prevalenceof raised blood pressure has increased, the change was entirely driven by increasingmean blood pressure, offset partly by the change in the prevalence-mean association.
