Dr. Eugenio Greco,
Treatment and control of hypertension are critically important for the prevention of consequent cardiovascular and kidney diseases.
Current estimates of the global burden of hypertension in high-income and low- and middle-income countries are needed to better understand this important public health concern. The proportions of hypertension awareness, treatment, and control that have been reported across many countries vary substantially. However, these data have not been systematically analysed to provide pooled estimates in world regions with diverse economic development.
The authors searched on MEDLINE the studies published from 1 January, 1995 to 31 December, 2014; additional studies were identified by manual review of references cited in reviews, meta-analyses, and original studies. Countryspecific searches of the World Health Organization Global Infobase were also conducted.
They included 135 population-based studies of 968.419 adults from 90 countries. Sex- and age-specific hypertension prevalences from each country were applied to population data to calculate regional and global numbers of hypertensive adults. Proportions of awareness, treatment, and control from each country were applied to hypertensive populations to obtain regional and global estimates.
The results of the study were:
The comments of the authors were that the study is the first systematic analysis of global health disparities in hypertension prevalence, awareness, treatment, and control. It provides novel insights into several aspects of the global challenge of hypertension:
The conclusions of the authors were that global hypertension disparities are large and increasing. Collaborative efforts are urgently needed to combat the emerging hypertension burden in low- and middle-income countries.
