Abstract:
Introduction: Hypertension is the leading preventable cause of premature death worldwide. We aimed to examine the global disparities of hypertension prevalence, awareness, treatment, and control in 2010 and compare secular changes in these disparities from 2000 to 2010. Methods: We searched MEDLINE from January 1995 to December 2014 and supplemented with manual searches of references from retrieved articles. A total of 135 population-based studies with 968,419 individuals aged ≥20 years from 90 countries were included. Sex-age-specific prevalences of hypertension from each country were applied to population data to calculate the number of hypertensive adults in each region and globally. Proportions of awareness, treatment, and control from each country were applied to hypertensive populations to obtain regional and global estimates. Results: An estimated 30.2% (95% confidence interval, 30.1-30.4%) of the world’s adult population in 2010 had hypertension; 28.6% (28.3-28.9%) in high-income countries and 30.3% (30.1-30.5%) in low- and middle-income countries. An estimated 1.35 billion (1.34-1.36 billion) people had hypertension in 2010; 349 million (339-359 million) in high-income and 1.00 billion (0.99-1.01 billion) in low- and middle-income countries. From 2000 to 2010, age-standardized prevalence of hypertension decreased by 2.3% in high-income countries but increased by 6.1% in low- and middle-income countries. During the same period, the proportions of awareness (56.6% vs 68.8%), treatment (42.9% vs 56.1%), and control (16.6% vs. 28.9%) increased substantially in high-income countries, whereas awareness (34.7% vs 35.1%), treatment (23.4% vs 26.4%), and control (7.0% vs 7.8%) increased only slightly in low- and middle-income countries. Conclusions: Global disparities in hypertension prevalence, awareness, treatment, and control are large and increasing. Collaborative efforts from national and international stakeholders are urgently needed to combat the emerging hypertension burden in low- and middle-income countries.
