Background: Hypertension is the leading risk factor for the global burden disease and in 2016 was associated with 10.4 million deaths for all causes. In Portugal, hypertension is the first risk factor for death and there are not studies about the trend of hypertension on 21th century. Objectives: The aim of this thesis is to conduct a systematic review of population-based studies regarding hypertension prevalence in Portugal, published between 2000 and 2018, with meta-analyses. Methods: A systematic search strategy was conducted in Pubmed using selected keywords (population-based; hypertension; prevalence; Portugal). References of known authors, Portuguese Statistics Institute, Portuguese Health Institute and articles suggested by the advisors were also included in this review. Results: Hypertension prevalence on 21th century in Portugal is 33% (95% CI: 27.6% - 38.8%, I2: 45%) and did not have significant difference between men, 35.4% (95% CI: 24.3% - 48.3%), and women, 32.9% (95% CI: 27,1% - 38,4%). In studies with physical exam hypertension prevalence is 37.1% (95% CI: 31.8% - 42.8%) although in studies with self-reported hypertension is 28.6% (95% CI: 23.6% - 34.3%). There is a statistically significant decreasing among studies with physical exam between decades (2000-2010 e 2011-2018) in age-groups <35 years of age, from 16.3% (95% CI: 12.9% - 20.5%) to 6.3% (95% CI: 5.3% - 7.6%) and =65 years of age, from 80.4% (95% CI: 76.9% - 83.5%) to 73.2% (95% CI: 69.5% - 76.6%). Conclusion: Hypertension has a high prevalence in Portugal. Self-report hypertension under-estimate the hypertension prevalence and an increasing prevalence is demonstrated with aging. However, further studies are necessary to identify the trend of hypertension on 21th, as well policies to improve evaluation, control and prevention of hypertension.
