Trends of the burden of hypertension in Saudi Arabia between 1990 and 2019: an analysis from the Global Burden of Diseases study

Abstract

Abstract Background: Hypertension is a widely prevalent condition associated with significant morbidity and premature mortality, primarily because it is a risk factor for CVDs. The aim of this study was to estimate the trend of the burden of hypertension in Saudi Arabia in the last three decades. Methods: We conducted a systematic analysis of secondary data obtained from the Global Burden of Disease Study (GBD). We estimated sex-stratified, age-standardised and age-specific rates (per 100,000) of prevalence, deaths, and disability-adjusted years (DALYs) associated with hypertension in adults aged 20-94 years in Saudi Arabia between 1990 and 2019. Results: In Saudi Arabia, the age-standardised prevalence of hypertension increased from 87.7 cases per 100,000 in 1990 to 94.9 per 100,000 in 2019. More women than men had hypertension throughout the past three decades. The death and DALYs rate, however, decreased during this time. In 1990, 9.2 deaths per 100,000 in women and 3.0 deaths per 100,000 in men were due to hypertension; the respective rates declined to 6.5 and 2.8 in 2019. While the rates of DALYs in women declined steadily from 211.7 to 151.8 per 100,000 DALYs between 1990 and 2019, the rate in males did not decline considerably. The burden of hypertension–prevalence, deaths, and DALYs–were greater in older people. Conclusion: The prevalence of hypertension has increased in Saudi Arabia during the last 30 years; however, death rates and DALY related to hypertension has decreased during this time. Age- and sex-specific strategies are needed to decrease the prevalence of hypertension in Saudi Arabia.
